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.
