I have a few Dell Latitude 7490 i7 laptops.
On most Leap 15.4 install, updates, reboots and works.
On some Leap 15.4 installs, updates, reboots, get the gui and panics with the caps lock blinking (kernel panic).
After a lot of searching the internet and lots of bad and incorrect info, I added 2 of the “fixes” to the bootup kernel parameters and no kernel panic - up for 12 hours now.
I had to add i915.modeset=0 nomodeset to the startup line to get it stable.
I am not sure why that fixed the problem. Have I disabled the i915 driver doing that?
Yes. You should open bug report.
Why does windows 10 and 11 have no problems on the same laptops that Leap panics on?
Here is what I changed to make it work.
LLRB:~ # head /etc/default/grub # If you change this file, run 'grub2-mkconfig -o /boot/grub2/grub.cfg' afterwards to update # /boot/grub2/grub.cfg.
