Hi
For the past 2 weeks, I’ve experienced random freeze about once per day. When this occurs:
- The entire screen is frozen.
- Cannot even move the mouse pointer
- Cannot switch to another tty Using Ctrl+Alt+F3
- It’s possible to connect on the affected computer using SSH on another computer
- Using
htop
using SSH shows a process related to x11 using 100% of 1 CPU - The affected x11 process doesn’t respond to
SIGTERM
orSIGINT
(usinghtop
) - Using
SIGKILL
does shut down the x11 process, and the CPU usage returns to normal, but the screen remains frozen. - Using
sudo reboot
reboots the computer but it takes like 2 minutes before it restarts (normally it takes less than 10 seconds)
The freeze don’t seem related to an app in particular. I remember them happening while using Shotcut, Firefox, Thunderbird, etc…
My setup:
- Fedora 37
- The computer is an Alienware X51 R2 with a Nvidia GTX 1060 graphics card.
- nvidia drivers are installed
- I’m dual booting. The other OS is Windows 10.
Unfortunately, I didn’t think of noting the full name of the x11 process. I’ll update this post when the next freeze occurs.
