==================

|
|
Graphics
|
|
--------
|
|
|
|
The kernel crashes frequently with graphical glitches. Add the following
|
|
to the kernel command line to prevent this:
|
|
|
|
i915.enable_psr=0
|
|
|
|
|
|
Crashes when locking or sleeping
|
|
--------------------------------
|
|
|
|
Still working out the cause for this one. Current troubleshooting steps
|
|
have been:
|
|
|
|
- Using X11 instead of Wayland: FAILED
|
|
- Using KDE Plasma instead of Gnome: FAILED
|
|
- Using XDM instead of GDM: FAILED
|
|
- Masking rtkit-daemon.service: FAILED
|
|
- Using newer kernel from Debian Backports: FAILED
|
|
- Using Fedora instead of Debian: FAILED
|
|
- Adding i915.modeset=0 to the boot line: TESTING
|
|
- Adding i915.enable_dc=0 to the boot line: TESTING
|
|
- Adding acpi=off to the boot line: TESTING
|
|
- Adding MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 to /etc/environment: TESTING
|
|
- Adding MUTTER_DEBUG_FORCE_KMS_MODE=simple to /etc/environment: TESTING
|
