nixos / nixos-hardware Goto Github PK

When following the README to add this repo as a channel, I get the following error at the next nixos-rebuild switch:

warning: Nix search path entry '/nix/var/nix/profiles/per-user/root/channels/nixos' does not exist, ignoring

This is consistently the case for me. It does not seem to happen, if I add the channel with a name not starting with nixos

Would be nice to automatically check that PRs are syntatically correct.

I added <nixos-hardware/lenovo/thinkpad/t410> to my configuration, and then got the error below.

warning: Nix search path entry ‘/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs’ does not exist, ignoring

Hi,
Im brand new to nixos, but trying to import the <nixos-hardware/dell/xps/13-9360> package.

  [ # Include the results of the hardware scan.
    <nixos-hardware/dell/xps/13-9360>
    ./hardware-configuration.nix
  ];

But im getting

The option `console.font' has conflicting definitions, in 
`/etc/nixos/hardware-configuration.nix' and 
`/nix/var/nix/profiles/per-user/root/channels/nixos-hardware/dell/xps/13-9360'.

The issue is that my hardware-configuration got autogenerated with

 # High-DPI console                                                                       
 console.font = lib.mkDefault "${pkgs.terminus_font}/share/consolefonts/ter-u28n.psf.gz"; 

And xps/13-9360 package also sets mkdefault on that attribute.

console.font = lib.mkDefault "latarcyrheb-sun32";

I use nixos stateVersion = "20.03"

Shouldn't services.fprintd.package also be set to fdprintd-thinkpad? (Introduced in NixOS/nixpkgs#61546)

The files under /sys/devices/virtual/dmi/id/ should allow most laptops, and probably brand-name pre-built computers too.

This could probably be used to detect available hardware configuration in some way, and the values could be used to help categorize the files in a way that is automatically searchable. Some of that information (modalias) is used in the udev hwdb to detect hardware and apply quirks to them.

I have attached a dump of the data in different classes of machines I own. This will help kickstart discussion and discovery of the helpful attributes.

The ArchLinux wiki is a wonderful source of information. It has a great deal of information on hardware support and is actively kept up2date. Let's piggy-back on it.

I can think of two things that could be useful:

• profile naming: there exists a lot of hardware out there. When in doubt with the profile name, that the name of the ArchLinux wiki page.
• profile info: link back to the ArchLinux wiki page. This will be useful to motivate various configuration decisions.

I think that we should piggy-back on it. For example if there is an ArchLinux wiki page for a specific hardware.

What do you think?

Does anyone know how to check if deep sleep is properly being forced on the XPS 9370? I'm seeing large battery drains while it's suspended again, and it resumes from suspend faster than I remember when I first enabled this "Fix".

Thanks.

It doesn't happen often, but sometimes when my laptop is really busy it will decide to shut down completely:

Nov 16 09:26:47 wmertens-nixos kernel: thermal thermal_zone3: critical temperature reached (80 C), shutting down

This is no fun obviously. Is there a way to have it instead throttle?

Has someone an idea for fixing or helping debugging the issue ?

I am new to NixOS Community, finally made my jump from manjaro to nix. I am not able to find a profile ready to be used with my laptop Thinkpad A485. I am using Thinkpad T495 since they beling to same lineup. I am facing the problem where once the system is put to sleep, it will not wake up. It is a request to add one config for A485.

Today I leaned that there is another driver from Intel that works with libva for accelerated video.

IF you add intel-media-driver to opengl packages, you can do this
LIBVA_DRIVER_NAME=iHD vainfo and see that a different driver is being used.

I don't really understand the pro/cons or any differences between using i965 and iHD, but I wanted to mention it since it doesn't seem widely documented/known.

I documented this on the related wiki page: https://nixos.wiki/wiki/Accelerated_Video_Playback

Regularly, to bind hardware ID ports to proper devices, if there are no ALSA mode supported - there can be a patch supplied.

[codec]
0x10ec0668 0x10431ced 0

[pincfg]
#Pin 12 is Internal Mic
0x12 0x90a60160
#Pin 14 is Internal "front" speakers
0x14 0x90170110
#Pin 15 is "Line Out" according to the manual, But Pin 15 won't work
#Trying to use this as an output will have a constant tone too.
#Using this as an output breaks the front speakers working correctly with detection
0x15 0x40f000f0
#Pin 16 is the headphone jack.
0x16 0x0321403f
#Pin 18 is the external Microphone jack.
0x18 0x03a19020
#Pin 19 is nothing.
0x19 0x411111f0
#Pin 1a is the internal subwoofer.  (Set the sound system to Stereo 2.1)
0x1a 0x90170151
#Pin 1b is nothing.
0x1b 0x411111f0

2. And then (/etc/modprobe.d/alsa-base.conf) sound.extraConfig =

options snd-hda-intel enable=1 index=0 enable_msi=1 model=asus-mode5 patch=asus-g752vt.fw

When I would get the setup working - I would submit it here.

But I do not know how to properly supply a patch, so I am asking in the best place possible - here.

I've added a test to see if the tree evaluates properly: fc9b7ae.

Evaluation should be fixed for all profiles in the tree.

Hi,

(First of all, this is my first time using NixOS on a physical machine - as opposed to VM or container - so I'm sorry if this is not the right way/place to report this!)

I just installed NixOS on a Dell XPS 13 2-in-1 (apparently that's the "7390" model). I used the minimal installation CD (from here). The WiFi interface (a "Killer Wi-Fi 6 AX1650i 201NGW") wasn't recognized. I installed over Ethernet, and after rebooting on the newly installed system, I noticed the following message in the kernel log:

[    3.829133] iwlwifi 0000:00:14.3: Collecting data: trigger 15 fired.

(Full kernel log in an attached file.)

After looking around, I found a few messages (here, here, here) suggesting that this is a regression in 5.4 kernels, but supposedly fixed. The kernel that I was running was 5.4.46 (nixbld@localhost) (gcc version 9.2.0 (GCC)) #1-NixOS SMP Wed Jun 10 18:24:58 UTC 2020.

Since this looks like a recent 5.4 kernel, I thought it would include the fix mentioned above; but just in case, I wanted to try to downgrade to a 5.3 kernel. I couldn't find how to do that, however I saw 5.5 and 5.6 kernels on NixOS, so I added boot.kernelPackages = pkgs.linuxPackages_5_6; in my /etc/nixos/configuration.nix, reconfigured, rebooted, and lo and behold, now the WiFi interface is recognized correctly (and after fiddling with wpa_supplicant, I got it to connect to my network).

I see this directory with configuration for this specific laptop. Would it make sense to add something there to use the 5.6 kernel? Or, since I expect that the "main" kernel will eventually work, should it be a note in the README there instead?

(For what it's worth, when I ordered that laptop, there was no way to get another WiFi interface with it, so I think it's the only WiFi interface that can be installed in it, but I'm not 100% sure either.)

Thank you!

kern.log

tp_smapi is not specific to this particular model, but works with ThinkPads in general: http://www.thinkwiki.org/wiki/Tp_smapi#Model-specific_status

hdapsd should be used for all laptops that have a hard drive, and any ThinkPad model might use SSD instead of a hard drive since it's not soldered in.

fprintd is commented out and thus not available if profile is read-only (#29). Fingerprint reader might or might not be available depending on laptop configuration.

Whether to use EFI boot or legacy boot and which bootloader to use should not be coupled with hardware configuration, in my opinion, for all devices except where it's explicitly coupled, like Raspberry Pi.

https://github.com/NixOS/nixos-hardware/blob/440088677b4e6f9527466cbc5b02abf2bf3f863d/lenovo/thinkpad/t410.nix#L35-89

Either POWERTOP or tlp should handle this.

This should be on for all hardware that uses Intel processors, unless user explicitly opts out.

Some options seem to be too aggressive, which goes against README saying that stability should be favored above all else.

This should be on for every machine that has a modern Intel processor with integrated GPU.

Larger problem is that ThinkPads don't usually warrant a per-model hardware profile. I still think it is useful to have a per-model hardware profile in case if things have to be fixed later on, but most configuration in these profiles could be just moved to common.nix.

Intel CPUs from Skylake onwards have a GPU microcontroller that can be used to offload certain tasks to the hardware.

More info:

• https://www.kernel.org/doc/html/latest/gpu/i915.html#guc
• https://wiki.gentoo.org/wiki/Intel#Feature_support
• https://wiki.archlinux.org/index.php/Intel_graphics#Enable_GuC_/_HuC_firmware_loading

Follow-up to #131.

I have a Lenovo C940 and it's pretty similar to the X1 but still different, and I want to build my own. However, I can't use flakes for that, I can't reach the intel, ssd etc modules.

@Mic92 ?

The generated hardware-configuration.nix files still use the now deprecated i18n.consoleFont attribute (it should now be console.font). Because of this you get warnings such as below

trace: warning: The option `i18n.consoleFont' defined in `/etc/nixos/hardware-configuration.nix' has been renamed to `console.font'.

First off, I really like the idea behind this repo.

We should abstract a bit more to find good optimizations that work for every thinkpad (or at least a category of them).

e.g. I factored out some in vuizvui:

{ lib, config, pkgs, ... }:

with lib;

let
  cfg = config.vuizvui.hardware.thinkpad;

in
{
  options.vuizvui.hardware.thinkpad = {
    enable = mkEnableOption "thinkpad support";
  };

  config = mkIf cfg.enable {
    # read acpi stats (e.g. battery)
    environment.systemPackages = [ pkgs.acpi ];

    # for wifi
    hardware.enableAllFirmware = true;

    hardware.trackpoint = {
      enable = true;
      emulateWheel = true;
      speed = 250;
      sensitivity = 140;
    };

    # TLP Linux Advanced Power Management
    services.tlp.enable = true;
  };
}

This piece of code also uses the power options give (e.g. I then use vuizvui.hardware.thinkpad.enable in my config). vuizvui is a bit special though, I don’t know if it’s viable to do with a drop-in module. @aszlig could tell us more.

In the hardware configuration file for Lenovo Thinkpad x1 6th generation, there are some configuration regarding charging thresholds.
As these are personal preference, shouldn't these be removed?

https://github.com/NixOS/nixos-hardware/blob/master/lenovo/thinkpad/x1/6th-gen/default.nix#L18-L19

See: https://github.com/yegortimoshenko/overlay/blob/0a861a7302e18c9ec88bb33139903ae67a930c03/modules/profiles/devices/macBookAir6x.nix

I also have a ThinkPad profile, but I'll open another issue about that.

System: Nixos 20.03

Output when importing this configuration:

<nixos-hardware/dell/xps/15-9500> works well

Don't know if it's possible but there should be a way to do something like <nixos-hardware/auto-detect> which would automatically include the right config for the device, which could enable including the right config in an automated fashion.

Otherwise a tool that just returns the right path or nothing if no hardware-quirk conf is needed would be cool

Hello, I've been using NixOS for a week, but I still have a problem: my touchpad seems to stop working from time to time for almost 3 minutes, and I have this problem like 7 times a day and all I can do is wait until he reworks again. I specified services.xserver.libinput.enable = true; in my /etc/nixos/configuration.nix, but I still have the same problem. I'm actually using an Asus FX504GD.
Did anybody encouter this issue and knows how to solve the problem ? I would be glad, thanks.

nixos-rebuild switch fails after first boot.

It's quite ridiculous that something mentioned during the installation phase of nixos doesn't even survive the installation phase...

Do you think we need a separate profile or we can use this one:

https://github.com/NixOS/nixos-hardware/tree/master/lenovo/thinkpad/t14s/amd/gen1 ?

It's very hard for new users to discovers this repository. Also, it belongs into the organization from a structural point of view.

https://github.com/NixOS/nixos-hardware/blob/master/lib/hardware-notes.nix#L21

Needs a description, it’s not very obvious what this is for (apart maybe from searching for examples).

I don't have a lot of experience with trackpoints, but coming from a mac I couldn't get the touchpad into a shape where I felt comfortable so I turned it off and rely on the trackpoint entirely.

Optimal configuration
(1) is there a consensus that the default trackpoint config is good? In https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/tasks/trackpoint.nix I can see that the default sensitivity is 128 and the default speed is 97. The Lenovo configs in this repo don't configure that.

I found that my finger started to hurt and the trackpoint seems to require a lot of pressure. I'm running libinput 1.9.4. Lots of users online say that the Linux Thinkpad trackpoints are not ideal - see a bunch of threads https://www.reddit.com/r/thinkpad/search?q=trackpoint+linux&restrict_sr=on&include_over_18=on

I bumped mine to 255 for speed and sensitivity in hardware-configuration.nix - but it didn't seem to be noticeable. cat /sys/devices/platform/i8042/serio1/serio2/{speed,sensitivity} showed the same values even after reboot. echo 255 | sudo tee /sys/devices/platform/i8042/serio1/serio2/speed" from the same thread clearly increased the speed, but did not persist on reboot. Is anyone else seeing this bug, or is it user error? I confirmed that the proper value was set with nixos-option hardware.trackpoint.speed.

In a thread from last week https://www.reddit.com/r/thinkpad/comments/8ea9eh/how_to_make_touchpad_and_trackpoint_work_nicely/ people suggest libinput 1.10.0 so I added the unstable nixos channel and just tried it (using nixos-rebuild test). Don't notice much different so far.

Other problems - hardware, worn out rubber, skill, expectations
Aside from configuration, I imagine that thinkpads have varying trackpoint hardware? Possibly different ideal sensitivities apply.

I'm hoping that I'll just get better with a trackpoint over time and it will be less painful.

I'm using a slightly worn trackpoint so I have fresh ones on the way https://www.amazon.com/gp/product/B072PQ7NT3/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Anyone out there super-happy with their trackpoints speed / sensitivity?

Other workarounds: I end up relying even more heavily on vimium in chromium and vim mode in editors since scrolling is so painful.

It would be nice to have information included in the modules such as

• The problems solved, and their symptoms
• Maintainers
• Which models are known to be covered

When I try to add Thinkpad T410 to my config i get the error: error: undefined variable ‘mkDefault’ at /nix/var/nix/profiles/per-user/root/channels/nixos-hardware/lenovo/thinkpad/intel.nix:2:24

I see that the variable is defined in the file common.nix but it doesn't look like this file is included in the profile or in intel.nix that uses the variable.

Please note, I don't have hard data for any of this, I can't say if these things are guaranteed improvements -- its more that I trust the Arch Wiki's XPS13 page and have been running these settings for sometime.

In my kernel params, I have some extras that aren't included via the xps-13-9370 file in this repository.

        "i915.modeset=1"       # entirely absent in nixos-hardware
        "i915.enable_guc=2" # entirely absent in nixos-hardware
        "i915.enable_gvt=1" # entirely absent in nixos-hardware
        "i915.enable_psr=1" # entirely absent in nixos-hardware
        "i915.fastboot=1"     # entirely absent in nixos-hardware

        "i915.enable_fbc=1" # set to 2 in nixos-hardware

I think I checked everywhere those could be getting set, but I could be incorrect about all of those being missing.

Thoughts from other XPS 13 users?

When I try to list available packages with nix-env -qaP the evaluation breaks in nixos-hardware/default.nix and I don't know what's wrong. The following logs are taken as root but it behaves the same with an unprivileged user.

The nixos-rebuild operations work as expected.

intel-hybrid-driver adds accelerated VP8/VP9 decoding to systems that normally don't have it, such as Bay Trail devices: https://github.com/01org/intel-hybrid-driver

I have included the hardware setup for T480s in my config like so:

    <nixos-hardware/lenovo/thinkpad/t480s>

But when I check using acpi I can see only one battery:

 > acpi
Battery 0: Discharging, 77%, 02:04:23 remaining

Same goes for the sys filesystem:

 > ls /sys/class/power_supply/   
AC  BAT0

But the device clearly has two:

The ThinkPad T480 comes standard with built-in Power Bridge technology. This innovation is the answer to 'low battery' warnings, especially if you are on the road or without a nearby power outlet. It allows you to swap out a battery and replace it with a fully charged one—without having to turn your machine off.

I also know because both were visible on Debian.

Hi there

I've been using the Lenovo X1 Extreme with NixOS and ran into a lot of problems regarding the hardware support.
Especially the hybrid graphics (Intel and Nvidia) including the HDMI outlet and the webcam don't seem to be working.

The ArchLinux people seem to have figured out most of the problems:
https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X1_Extreme

I would love to continue using NixOS on this device.
Are there any plans to extend this overlay for the X1 Extreme?

Thanks a million

Everyone who sees this page will know where it is ;)

At least, assuming it's generally valuable.

I had no idea this existed, and just ran into it by accident. For bonus points, have nixos-generate-config propose the profile addition.

NixOS/nixpkgs#69150 holds an info on a hardwire-related issue, solution was:

"
ideapad_laptop module created a 2nd brightness device in addition to intel_backlight. Moving the slider made ideapad/brightness change which meant that the actual brightness didn't change. The fix:

boot.blacklistedKernelModules = [ "ideapad_laptop" ];

"

I'm not fully sure of all of the implications, but the last cause of problems with CPU scaling on my XPS 13 9370 was tracked down to weird combinations of my USB Type C Hub and various Type C power supplies that I have around.

Using msr-tools and executing sudo wrmsr -a 0x1FC 2 "fixes" this problem.

I don't fully understand the implications of this, so I'm not going to send a PR right away, but I thought I'd offer it for consideration (and as a potential warning to others in the future).

Also, in the interest of potentially helping other XPS users, the Nov 2018 firmware update has been a big improvement to performance and consistency.

Hi there,

cc @Alecktos @Mic92 as you seem to have this laptop model, too (deducing that from your collaboration on this file https://github.com/NixOS/nixos-hardware/blob/master/dell/xps/13-7390/default.nix)

I have frequent screen freezes in pretty random situations/frequency. (Yesterday with a specific USB c hub it was a freezing screen roughly every minute for 1 second).
After going through some forums and finding experiences/fixes of other users, i got this fixed by setting:

boot.kernelParams = [
  "intel_idle.max_cstate=1"
  "i915.enable_dc=0"
];

With this setting the freezing is gone and the whole laptop feels much more responsive.

Is that something that other 7390 users experienced (on linux / NixOS), too, or is my experience here completely odd?
If it's not just me i'd open a pull request on that file adding this setting.

I'd like to get up and running on a new system without remembering to add the channel beforehand. Is there a way to do this with, for example an overlay?

I think this is related to move to "throttled" to fix the intel throttling issue on various laptops.

While trying to use undervolt last night, I realized that something is still overriding the temperature target. Watch:

[cole@xeep:~/code/nixcfg]$ sudo undervolt --temp 97

[cole@xeep:~/code/nixcfg]$ sudo undervolt --read
temperature target: -3 (97C)
core: -99.61 mV
gpu: -75.2 mV
cache: -99.61 mV
uncore: -99.61 mV
analogio: -99.61 mV

# wait a second

[cole@xeep:~/code/nixcfg]$ sudo undervolt --read
temperature target: -5 (95C)
core: -99.61 mV
gpu: -75.2 mV
cache: -99.61 mV
uncore: -99.61 mV
analogio: -99.61 mV

And yet:

not sure what to add here, but wanted to at least file an issue as a todo item.
