Body:
Hi everyone,
I am experiencing a severe and frustrating issue with my Fedora installation (KDE Plasma) where my display completely cuts off (Black Screen / No Signal), forcing me to hard reset the system. I would appreciate any help or guidance on how to properly diagnose and fix this.
My Hardware & Environment:
- OS: Fedora Linux (KDE Plasma desktop environment)
- GPU: NVIDIA GeForce RTX 3060 Ti (Using proprietary drivers)
- Triggers: The crash happens randomly but frequently during hardware-accelerated web browsing and when running 3D applications/games (such as Roblox via Wine/Proton or Besiege).
The Problem Description:
When the crash occurs, the monitor suddenly loses the video signal entirely and goes black. The PC components stay powered on, and background audio sometimes continues for a moment, but the GPU completely stops outputting any display.
What I Have Attempted During the Crash:
- TTY Switching: I tried switching to a virtual terminal using
Ctrl + Alt + F3(and other F-keys) to kill the offending processes, but the monitor remains completely black with “No Signal”. The display pipeline seems entirely frozen. - Display Manager Restart: I attempted to blindly restart the display manager, suspecting a Wayland/X11 session crash using:
Bashsudo systemctl restart sddmHowever, because the display output is completely dead, this does not recover the monitor signal. - Magic SysRq (REISUB): In some instances, the system is so heavily locked up that even the REISUB key combination fails, forcing me to use the physical power button to hard reset, which I want to avoid to prevent data corruption.
Troubleshooting & Context:
- I suspect an issue with the current kernel module integration or a severe conflict between the proprietary NVIDIA driver and the display server (especially under Wayland configuration parameters).
- I’ve tried switching sessions and keeping configurations clean, but heavy GPU tasks consistently trigger this driver kilitlenmesi (lockup).
Could anyone guide me on which log files to inspect (e.g., specific journalctl flags or Xorg/Wayland crash logs) right after a forced reboot to catch the exact error line? Are there known kernel parameters or stable driver rollbacks recommended for the RTX 3060 Ti on Fedora right now?
Thanks in advance for your support!
