I have noticed this issue since in last update (.69) of kernel, I have apt-mark hold the upgrade of the kernel and hopefully the issue can be fix on .73.
As I spot a new issue of kernel I try to unhold and upgrade but the x11 server cannot start.
My graphic card is old GTX960 and my system is Debian 13.
When the issue happened, I use timeshift in text mode and restore back to .63 and X11 work fine.
update : I have resolved myself
