I'm running openSUSE Tumbleweed with an Intel UHD Graphics 630 (Desktop) and
the modprobe i915 driver.  I use Plasma as my desktop environment, and this had
been working without significant problems since I first set up the machine
around April 2019.  But for the last month or two, I've been experiencing a
problem whereby my entire desktop (both screens on a dual-monitor setup) go
completely black.  I can't reliably reproduce the problem, though it happens
several times a day, usually (but not always) when I'm using the mouse to
drag-select.  Sometimes the display stays blank for only a second, but
sometimes it freezes that way until I press a key on the keyboard.

On the assumption that this is a graphics driver issue, here's the output of
hwinfo --gfxcard:
