List of things I have to Inform you what I have tested.I am Computer Science student but new to linux so I have tested many things.
1. I have used both x-org and nvidia GPU. After fresh installation and on reboot I got into many problem my touchpad and brightness controller were not working and screen glitch so i fixed my brightness and touchpad using ubuntu community posts. But glitch were all same I have tried many solution but not solved. so I posted ubuntu-bug. 2. I have changed setting from bios to disable NVIDIA but glitch problem not solved. And on using NVIDIA Driver there were not glitch performance were perfectly fine but on restart i got stucked on boot menu screen were blank so i ran into recovery and change my driver to x-org intel. 3. Before bug submission I have tested around 10 popular linux distro all were having same problem screen glitches. 4. only two distro have not occoured a display glitch problem one was ubuntu 20.04 LTS and ubuntu budgie 21.04 but that distro causes same touchpad and brightness controll problem that was so frustating. So I came to conclusion that my intel driver is buggy and on reboot my device alwaay fail to recognise touchpad and display driver. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1937072 Title: Incomplete screen redraws To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1937072/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
