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.
