fatal IO error 11 (Resource temporarily unavailable) on X server ":0"

[AndreasBackx]

Whenever I use i3lock -f my monitors blur for about 1 second, then unblur, and then it seems like it's frozen for a while. I cannot use my mouse, I cannot enter my password to unlock it, nothing seems to be giving any feedback. After a while it "unfreezes" and throws the following error:

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 4920 requests (4920 known processed) with 0 events remaining.

The amount of requests (4920) differs sometimes. Note that using i3lock by itself works just fine.

Some information about my machine:

• Arch Linux 4.11.9-1
• GPU: Nvidia GTX 1070
• GPU driver: Nvidia proprietary driver 318.22.
• 2 monitors, 1 in landscape, 1 in portrait, both 1440p.

If there's anything else you'd like to know, I can provide that.

This was tested on the master branch and on the version that's on AUR as of writing this issue which is 2.9-1.

Bump

I suggest to use the -o flag for now. This is available in the master branch. This does the blurring only once at the startup. The blurring still uses OpenGL and is fast.

Still same problem.

      after 1121 requests (1121 known processed) with 0 events remaining.

There is also issue #6. To summarize the discussion there: Please try to use --nofork.

[faurehu]

--nofork works one or two times before it freezes on the blurred screenshot and I can only restore my system with a hard reboot.

[karulont]

I can only restore my system with a hard reboot.

Can't you use CTRL+ALT+FX to switch to a different tty and then issue sudo killall i3lock?

[faurehu]

@karulont yes I can, just learned about this thanks :)
