To make use of the graphics driver, I update the kernel from 5.4 to 5.13. The computer is booting up, the LM splash screen apprears and then the screen gets funky with a random assignment of pixels. It seems each pixel gets a random assigned color (white, red, blue, green?, black). The pixels change color roughly every 200-500 ms. This happens with 5.13.0-28 and 5.13.0-23. The laptop is not responding to anything. Using 5.11.22 works without any flaws. AMD gpu drivers are installed correctly. Mandatory information 1st: This one is running: Ubuntu 5.11.0-43.47~20.04.2-generic 5.11.22 Description: Linux Mint 20.3 Release: 20.3 description: Notebook product: 82LM (LENOVO_MT_82LM_BU_idea_FM_IdeaPad 5 14ALC05) vendor: LENOVO version: IdeaPad 5 14ALC05 serial: MP1XXXXX width: 64 bits To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.13/+bug/1960159/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
