Use the computer for anywhere between 2 min and 20 min, eventually applications freeze
Symptoms: Screen flickers and applications freeze after resuming from suspend. Eventually the machine locks up.
NOTE: this error only occurs when I have HDMI plugged into an external monitor.
I will paste the output of dmesg the next time I reproduce it. If there are any other commands to run, let me know. Ya’ll should really put a big old button about “how to submit an issue”, fwiw.
Some workarounds, from System76 support (seems to apply to all recent Ubuntu, though). YMMV.
We’ve been tracking this problem on this hardware with this 1060 video card. It’s related to the NVIDIA driver and just the particular hardware, and it’s not completely consistent.
Trying different versions of the NVIDIA driver may help, but we haven’t narrowed down the fix quite yet. We will soon! Until then, if you turn off hardware acceleration in Chrome that will help. Also, in the NVIDIA control panel, in the OpenGL tab, turning off ‘Flipping’ will fix this issue, but introduces video tearing at times. Until we track this down, that’s what we recommend.
