Bug Description
After upgrade from Ubuntu 18 to 20, touch-pad and display stop working correctly. touchepad works only from time to time, but I can't find pattern why. On the other hand display just after upgrade worked correctly, but lately I have to work in recovery mode because on normal drivers refreshing is terrible and from time to time display turn black and it is impossible to switch it to normal mode.
