Hi, there! ✌️
I'm Elias* and this is my GitHub profile. (bit messy, don't look too closely 😉)
Description
Expose another http endpoint for temporary displaying a URL for given amount of seconds and then it goes back to the previously displayed URL.
Possible Solutions
Expose endpoint /display_temporary with get params url and 'duration'. The duration param gets integer value specifying the duration of seconds. After these number of seconds are passed, it loads the previously loaded URL, the one before the /display_temporary request occurred.
Additional Context
This feature would be very useful in cases like:
After some time passes, displays return to their previously displayed page.
I opened the code and saw that arg description is mostly copy/paste from the window's width and height ones.
Description
When running it I get a blank screen and this error on the terminal:
Overriding existing handler for signal 10. Set JSC_SIGNAL_FOR_GC if you want WebKit to use a different signal
This error seems to be a because of a bug in webkit2gtk-4.0 versions above 2.32. The current version is 2.36.3.
I tried to understand how to workaround it and got here - a fix in Wails for exactly this issue:
wailsapp/wails@e015517
And here is the thread: wailsapp/wails#658
How To Reproduce
apt-get install webkit2gtk-4.0 (install latest version, e.g. currently that is 2.36.3-1)
Expected Behavior
Show the webpage
Actual Behavior
Blank screen
Do we need a full-blown Gnome? I'm trying to setup DashD on Armbian without GUI. I see that we can use xX.Org Server for a window manager. I'm unable to install gtk-3 however on the Debian Bullseye Armbian (it says there's no such package). Can you please state minimum software requirements?

From what I understand, this issue could be because of multithreaded CPU. Go runs the http on another goroutine.
This is a thread with more info: golang/go#26698
How To Reproduce
Just run on a multithreaded CPU.
Description
How To Reproduce
Run
sudo /usr/local/sbin/dashdon non-raspberry arm board and no ws2811 hardware.
Any way we can disable Lighting if it's not used?
The DashD project seems exactly what I'm looking for to put on my armbian boards around my home and turn them into proper kiosks. I'm really excited about the HTTP control (make a request to a particular display to load a web page). However I have no idea how to use the DashD binary. There's no documentation available. I tried to wild guess it, but so far unsuccessfully. Can you please provide such information in the README, plus an example? Really, really thank you!
