That didn't work either. Using the "intel" driver with:

      Option "AccelMethod" "UXA"

still resulted in the following GPU HANG:

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.
