Title:
Latest kernel breaks LCD screen
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi,
I just installed Lubuntu 22.04 on a brandnew notebook, and everything
was working well until rebooting after update:
Both the boot splash and the X11 screens are jumping and appear
instable afer a few seconds, as out of sync and running through. It
absolutely looks like a hardware problem like a broken LCD connector
cable, but it isn't: booting fresh from the Lubuntu usb stick and
evernything works. I have a second machine, exactly same model and
installation procedure, which was working well for some weeks and had
exactly the same problem after upgrading.
disabling the boot splash did not help.
But booting into the older vmlinuz-5.15.0-25-generic , that came with
the Lubuntu installation iso file, instead of the latest
vmlinuz-5.15.0-41-generic solved the problem. With the older kernel,
everything is stable and fine.
So between the 25 and the 41 revision of the kernel there came
something in which reliably breaks the screen configuration on both my
two notebooks of identical hardware.
Both the X11 login screen and the desktop do work normally for about
five seconds and then start running through like one of these old days
analog screens when out of sync or a cable not plugged in correctly.
