I'm guessing I need to replace my video card, but would appreciate
confirmation, or guidance from anyone with knowlege of this stuff.
There's a lot I don't know about devices and their drivers, but I
think I have a failing video card.
Everything looks good on-screen, except that for the last few days
things have been a bit slow.
I didn't pay much attention to it until I noticed that my root
directory is full.
/home is not on the root partition, fortunately, so the impact is
minor. So far. But I tracked it down to kern.log and syslog. They
had grown to 40 GB between them. There were a huge number of
essentially identical entries, up to dozens per second. They looked

[IO_PAGE_FAULT device=01:00.0 domain=0x0014 address=0x0000000000256000
This is pretty cryptic, but the device=01:00.0 seems to match this
line of output from lspci(1)

One further bit of evidence. These lines are added as long as the GUI
is on my monitors (I have 2). They stop being added if I Ctl-Alt-F1
to a console login.
This seems like a fair bit of evidence, but it's clear outside my expertise.
