  • System is unusable after upgrade to ubuntu 20.10

    https://askubuntu.com/questions/1288395/system-is-unusable-after-upgrade-to-20-10-i915-gpu-hang

    Having updated to 20.10, it now boots okay and the login screen appears normal. The desktop is fine until I try to open any application. The application name appears at the top, and then the desktop completely freezes. In some cases the app icon in the dock becomes pixelated. Sometimes a portion of the desktop flickers to solid black.

    The mouse still moves occasionally, and I can CTRL+ALT+F3 to a command line.

    Various searches suggest a graphics driver problem. It's an Intel Haswell graphics chip.

    I've tried both the Ubuntuand Ubuntu on Wayland options at log in, both give the same results.

    这个问题直到linux内核5.9版本都没有解决!
