Display socket is taken but lock file is missing about headless HOT 14 CLOSED

This fixed this issue for me on macOS El Capitan:

mkdir /tmp/.X11-unix
sudo chmod 1777 /tmp/.X11-unix
sudo chown root /tmp/.X11-unix/

from headless.

Had this problem too.

Needed to just run Xvfb and/or quartz-wm once and that solved the issue.

Apparently, that created the /tmp/.X11-unix/ folder, not sure if it created something else.

from headless.

This is an issue on every reboot. My assumption is that /tmp is clearing and I have to recreate the file each time. macOS Sierra 10.12.4, XQuartz 2.7.11. (Edit: also worth noting -- this is the only thing i use XQuartz for)

from headless.

The manual fix is described here.

Are you doing something else with the XQuartz? And please post your Headless.start arguments.

The manual fix (pkill Xvfb) is a no-op for me - I can't even find a running process named Xvfb (ps aux | grep -i xvfb doesn't show anything).

My arguments to Headless.start:

Headless.new(display: 100, reuse: true, destroy_at_exit: true).start

I also tried it with no options at at all (Headless.new.start) to see if using the defaults was all I needed to do. I get the same exception.

Let me know if I can provide more info or help in any way.

from headless.

I see this consistently using the Ubuntu 14 environment on Circle CI. My Headless settings are: Headless.new(reuse: true, destroy_at_exit: false)

☝️ This worked for me using Capybara with Sierra.

from headless.

on osx EI Capitan (10.11.6)
Xfvb version: from XQuartz 2.7.9
ruby version: 2.3.1

gem uninstall capybara-webkit
brew tap homebrew/versions
brew install qt55
brew linkapps qt55
brew link --force qt55
gem install capybara-webkit

Works fine for me: Headless.new(reuse: false).start

from headless.

any updates on this? I also have the same issue on every reboot. Sierra 10.12.6, xquartz 2.7.11

from headless.

Does this happen every time? If it's a one time situation, there's a manual fix, but it shouldn't be a recurring thing.

from headless.

This error is recurring for me. I also get it while running tests. What's the manual fix?

headless version: 2.1.0
Xfvb version: from XQuartz 2.7.9
ruby version: 2.3.1
OS: OSX 10.11.4

from headless.

Unfortunately, I can't solve this issue because it's a fundamental X server requirement to have a /tmp/.X11-unix directory and have it owned by root. In addition, since macOS does clean /tmp on reboot, you need to set the directory up every time.

Fortunately, XQuartz.app will do that for you, so a simple solution is to add XQuartz.app to login items.

The only thing I can do is improve the error message, and document the solution here: https://github.com/leonid-shevtsov/headless#tmpx11-unix-is-missing

Installing chromedriver fixed this for me (on a mac brew install chromedriver).

@btucker 's fix worked for me.
