Hello there, For a few months I've been experiencing occasional freezes of the X11 display on my QubesOS RENOIR laptop. The setup is pretty much standard for QubesOS, with both GPUs attached to dom0 and XFCE running there (and the dGPU being mostly not used). Kernel is QubesOS' kernel-latest-6.15.4.
Those freezes most often occur while the screen is blanked by xscreensaver (suspend options fully deactivated here, as suspend is broken on this platform): in this case moving the mouse does not get the unlock banner displayed, the screen stays black... except the mouse pointer is visible. I can also switch to other virtual consoles and interact with the system, but was never able to collect any evidence of something wrong being detected. Occasionally it also happens (like yesterday) while I'm working, and the X11 display just seems frozen, no clue if the input devices trigger anything in there. I guess something goes wrong but gets undetected by the driver. Any suggestion as to extra logging/debug features to enable? Best regards, -- Yann
