Greeter crashes when using Dummy Xorg monitor (` xf86-video-dummy`) and Vulkan on Linux #159

Closed adamency closed 4 months ago

adamency commented 4 months ago

I have a headless Arch Linux system which I access remotely via LightDM and remote desktop software. The setup is Xorg dummy monitor (xf86-video-dummy) + lightdm + lightdm-gtk-greeter + i3.

It has always worked well until several weeks ago. Now lightdm-gtk-greeter is always crashing at boot and thus prevents me from using LightDM on my system which I generally can only access remotely.

Here is the only explicit error message I get (having looked at lightdm logs lightdm-gtk-greeter logs, i.e. all logs in /var/log/lightdm and journalctl logs Lightdm):

ERROR:             ICD associated with VkPhysicalDevice does not support GetPhysicalDeviceCalibrateableTimeDomainsKHR

Btw, It only happens when using the dummy monitor and works correctly with a real physical screen.

lightdm-gtk-greeter -> 1:2.0.8-3

Actually an update to 1:2.0.9-1 was uploaded to the repos some days ago and seems to have fixed the issue*. I'm leaving this issue here for visibility to other people having the same problem, and if maybe it is possible to discuss what was the cause of the issue because I can't seem to find anything related in the changelog for the new version.

*but I also switched from dbus-broker (new Arch Linux default since 2 months ago) to original dbus at the same time so can't be sure if it's the only cause or I needed both the greeter update and this
