I managed to recreate the problem (more on that in a bit). The kern.log
indicates again that a crash dump was saved in /sys/class/drm/card0/error (like
before), however a listing of that location shows:

$ ls -l /sys/class/drm/card0/
total 0
drwxr-xr-x 4 root root    0 Nov 26 00:15 card0-LVDS-1
drwxr-xr-x 3 root root    0 Nov 26 00:15 card0-VGA-1
-r--r--r-- 1 root root 4096 Nov 26 00:15 dev
lrwxrwxrwx 1 root root    0 Nov 26 00:15 device -> ../../../0000:00:02.0
-rw------- 1 root root    0 Nov 26 00:15 error
drwxr-xr-x 2 root root    0 Nov 26 00:15 power
lrwxrwxrwx 1 root root    0 Nov 26 00:15 subsystem -> ../../../../../class/drm
-rw-r--r-- 1 root root 4096 Nov 26 00:15 uevent

So maybe it didn't save anything. The machine is still in it's "darkened"
state.

I recreated the issue by selecting a particular icon on the MS Outlook
website... In Google Chrome. When I select the icon that is supposed to show me
the contact list, the graphics driver goes into this state and the screen goes
blank.

I have seen the same issue on other occasions, so I know there are other
interactions that can cause the same. However this "contact list" function
seems to recreate the issue consistently - at least it did so twice in a row.
