Public bug reported:
Hello,
I recently installed Ubuntu 22.04.4 on a Lenovo V145-15AST laptop.
Randomly, the screen will start flickering. I have found that pulling
the power cable out sometimes solves the issue ! But even so, with the
power cable out the screen can still start flickering. It's completely
random, but very distracting.
I am treating this as a bug as I have looked at the options in "Settings
> Screen Display" and non of those seem to make any difference.
Also I previously tried to install Linux Mint 21.3 and in that case, while
booting from the usb stick, I got the welcome to linux mint menu which allows
me various options and I select "Start Linux Mint"
After that the spinning mint logo appears, then a small mouse pointer on a
black screen then the screen goes into some sort of error, a black screen with
a few lines at the top.
Selecting "Start linux mint in compatability mode" does boot to mint but then
the trackpad does not work.
I have included this reference to Linux Mint as I believe mint is based
on Ubuntu.
Many thanks,
Nick.
