Hello i just installed lubuntu on my friend laptop. the installation went smooth and not any error shown But after installation finished when system trying to shutdown / restart the display freezes. i did try to access tty but to no avail so i ended up using REISUB to reboot the computer somewhat forcefully

installed OS runs fine and everything works fine so far. but every time i try to shutdown / reboot the pc display freezes again and wont shuttdown after waiting more than 3-4 minutes.

i tried to access tty upon starting the system normally but to no avail and the display freezes again.

is there anything i can do to fix this problem it seems weird to give installed OS with freezing display upon rebooting/shutdown.

the only modification i did upon installation is apt update && apt upgrade and also installing mesa-utils to find which display driver used.

feel free to ask again if my explanation isnt clear enough
