Comment 22 for bug 1798961

I have the same problem very often during a day on a Lenovo ThinkCentre M900 (see specs below).

Often this problem is preceded by Chrome tabs blinking or blacking out but I can't be sure it is a related problem. In those cases, the only solution is to kill Chrome and restart the application.

When Ubuntu freezes it starts with either a frozen cursor or unable to use the cursor anywhere. Other times Ubuntu becomes very slow before freezing.
