That didn't work either. Using the "intel" driver with:
Option "AccelMethod" "UXA"
still resulted in the following GPU HANG:
[drm] GPU HANG: ecode 9:0:0x85dffffa, in compiz [3398], reason:
Hang on rcs0, action: reset
i915 0000:00:02.0: Resetting rcs0 after gpu hang
[drm:gen8_reset_engines [i915]] *ERROR* rcs0: reset request timeout
i915 0000:00:02.0: Resetting chip after gpu hang
[drm:gen8_reset_engines [i915]] *ERROR* rcs0: reset request timeout
[drm:i915_reset [i915]] *ERROR* Failed to reset chip: -5
After all these tests, my current guess is that the hardware
acceleration in my Web browsers (Firefox and Chromium) is triggering the
error in the graphics driver or firmware.
I disabled the hardware acceleration in Firefox and Chromium. I also now
avoid running anything that uses Electron, such as the Skype and Signal
desktop snap packages, because I don't know how to disable the hardware
acceleration in an Electron app.
After about a week, the problem occurs now only if I forget and leave
Skype running for an afternoon. I'm hoping this can continue to function
as a simple work-around.
