Hello, I'm having the same bug. Me too I have to switch to the console with Ctrl-Alt-F1 to revive the graphical console. I found that the following is sufficient to revive the display from the blank screen:
chvt 7; DISPLAY=:0 xrandr --auto The second part of the workaround was found in the logs of this bug, but the first part is easier than the previously proposed hack: delaying the xrandr and manually switching to the vt 7. My settings: $ dpkg -l xfce4 upower light-locker nvidia-kernel-dkms|grep ii; uname -a; lspci |grep -i nvidia ii light-locker 1.8.0-3 amd64 simple screen locker for lightDM display manager ii nvidia-kernel-dkms 470.141.03-1 amd64 NVIDIA binary kernel module DKMS source ii upower 0.99.20-1 amd64 abstraction for power management ii xfce4 4.16 all Meta-package for the Xfce Lightweight Desktop Environment Linux cafuron 5.18.0-4-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.16-1 (2022-08-10) x86_64 GNU/Linux 01:00.0 3D controller: NVIDIA Corporation TU117GLM [Quadro T1000 Mobile] (rev a1) Thanks,
