My Notebook with Ubuntu 18.04 freezes after resuming from suspend. How to debug?
My Notebook with Ubuntu 18.04 freezes after resuming from suspend. It shows a weird pattern on the screen:
No mouse pointer visible. No keys have any effect. Ctr+Alt+F? doesn't work either.
Before the upgrade to 18.04 suspend and resume worked fine.
My notebook is a DELL PRECISION M4800. Config-About shows the following graphics: Quadro K2100M/PCIe/SSE2.
