W. Pepperdine, Debian User list might be the best place for raising your issue. I tried to find your post in Debian User but was not able to, which might be why people did not respond.
If it helps, I use XFCE on Debian bookwork myself without any issues (and have a number of PCs running KDE too). I really like XFCE. I do not have the issues you mention. Maybe this can give you hope that Debian XFCE should work well. I would assume that if you run the below command from a terminal as root, it will display an Intel GPU is being used? # lspci -k | grep -A 2 -E '(3D|VGA)' While not particularly powerful I have found the Intel GPUs that are within i5 and i7 processors to work effectively and are well supported in Linux thanks to Intel's video driver. If you are doing a standard Debian Bookworm installation, then sadly I suspect that your M920q has a hardware fault. I am only guessing but maybe memory? Maybe CPU. After looking up the M920q I assume it does not have a slot for adding a Video Card, but relies on the internal GPU of the CPU. Not that this should cause an issue. I have used the Internal GPU on Intel CPUs before, and for XFCE/LightDM too. I find this command useful for checking the display manager. $ env | grep -E -i 'x11|xorg|wayland|plasma' You could try Gnome or KDE instead of XFCE, but I doubt they will work any better. Maybe you can test memory by installing Memtest86+ and rebooting to select and run Memtest86+. I cannot recall clearly, but I think I had issues being able to do this due to UEFI? Maybe the free version from memtest86's web site will work? Install it to a bootable USB memory drive. https://www.memtest86.com/ I do no think my comments help that much, I hope you find a solution.
