Comment 0 for bug 1750664

Even after clean installation, the system is crashing randomly and logs out, everything not saved is lost. No proprietary drivers, no extensions, nothing installed from outside Ubuntu Store (only Chrome), no applications messing with GNOME or UBUNTU itself.

Ubuntu Bionic Beaver 18.04
Samsung ATIV Book 2
Intel Core i5
Intel HD Graphics
Nvidia G-Force GT710M 2GB
