After installing ubuntu 20.04 on my windows device Lenovo IdeaPad 320 I face multiple problems like hangs and system crashing.
It works normally but suddenly it hangs and I have to restart the computer. Sometimes during boot, it shows up some weird message.
One thing to note, it does not appear every time. Also sometimes it gets worse and when I try to restart it start noising.
How to fix this problem? Why Ubuntu is not compatible with my device?
