Dell Latitude 7490
==================
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: FAILED
- Adding intel_idle.max_cstate=1 to the boot line: FAILED
- Adding acpi_osi='Windows 2018' to the boot line: TESTING
- Adding i915.enable_dc=0 to the boot line: TESTING
Currently the "acpi_osi='Windows 2018'" kernel option seems to be
working.
