Cage crashes when HDMI output is requested

enolp commented 3 years ago

Sorry for the title of this issue but I don't know how to name it.

Ok, so I 've debugged a big bug which causes cage to crash over a HDMI connection. Here are the results:

Pausing cage process and switching off/on my monitor, cage process does not crash and I can get it working after resuming it.
Un/plugging HDMI cable and switch my monitor on/off when cage is running, makes cage crash. Logs from various applications by using cage APP 2> log.log method:

Firefox (wayland mode): Log Chromium (Xwayland mode): Log Kodi (wayland build): Log VLC (Xwayland mode): Log

I'm using Arch Linux under UEFI and the the screen resolution is set by KMS. My packages are: acpi acpi_call base cage cpupower ethtool intel-ucode kodi-wayland libva-intel-driver linux linux-firmware mesa upower vulkan-intel xf86-video-intel xorg-xwayland. Cage version is 0.1.4-646b3e8

Is this not just Cage shutting down due to the last display being disconnected?

After seeing https://github.com/Hjdskes/cage/issues/208 and https://github.com/Hjdskes/cage/pull/213 I'll wait for changes on this behavior. VGA output seem to be unaffected.

Is there any way to workaround this until this behavior changes?

It seems the described issue is the same than #208, now fixed. I think this issue can also be closed.

@enolp, could you give it a try with current version of Cage?

I've tested the last git revision of cage and now everything works as expected. No more crashing when I turn my TV on or off. I'll close this issue right now
