Hello again Daniel, Thank you very again much for your help and again, my apologies for being unable to reply to your sooner. I have found recently that my laptop, the Lenovo V145-15AST has stopped suffering from a flickering screen. I have used the laptop extensively for normal work and the problem has disappeared. There have been two updates during the course of our discussion. Although I'm finding it difficult to give you any detailed information as typing "lsb_release -a" at the terminal only results in;
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.4 LTS Release: 22.04 Codename: jammy I'm not sure how to let you know what was installed during the two updates, as I'm sure that would help. Many thanks again for all of your help in this matter, Nick. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2055037 Title: [amdgpu] My screen randomly starts flickering Status in linux-hwe-6.5 package in Ubuntu: Incomplete Bug description: 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.
