On Fedora 17 and 18 I sometimes get a display like nothing else I
know. It's made up of short horizontal lines, some in color, arranged
into long diagonals that cover the screen, with about the angle of a
backslash. The little lines in each group are parallel, and there's
always a little space between every group and the next.
It comes up suddenly, on a key press or a mouse click.
Once it comes up, it owns the machine -- nothing the mouse or
keyboard can do (that I know of, anyway) has any effect, and I have to
hit the reset button.
I have yet to discover any correlation with any user action :
afaict, some power of darkness arms the trigger, apparently randomly, and
the next thing I do brings on the crash.
Has anyone else seen this? Diagnosed it? Found any prevention or
cure??

Yep I get the same particularly with Firewalld and
NetworkManager/Connections. Its only on one machine, all my others are fine.

I should have mentioned that this screen arises on at least three
machines, running F17 fully updated, built for me by two different alpha
technoids, years apart.
I suppose it could still be a cooling problem, because I do much
the same things on two of them; but my spouse uses the third very
differently. (I have a couple more F17 machines, but use them less, and
one currently has an (I think) unrelated problem.)

I know. However, you can always put it at one end, so that it's not
stuck between two other cards.

Would'nt help me because there's only one card with nothing around it
for miles, it still got v.hot

One of my friends is a hardware geek. He recommends leaving one slot
open between each two cards whenever possible to improve ventilation.
Not sure if this would have helped in your case, but it's worth
mentioning.
This would be particularly important for the video card, especially if
it has its own fan. But modern mobos don't have that many slots anymore,
so that could be a problem! (I wonder if anybody makes a "slot
extender?" I guess it would plug into an existing slot and run by a
cable out
the back of the computer. It would make for some ferocious RFI!)

I had this once, or many instances over a certain period of time, and
am still using the same graphics card. I don't think ours
heat-related; I can't remember what I did to fix it.
Probably unrelated but this reminds me, I had graphics/display issues a
year or two ago and put set up a huge fan on the graphics card blowing
on the heat sink. Not a problem with graphics ever since.

Probably, your graphics card is dying. If you have a separate card, get a
new one.
If it's part of the motherboard, get a new motherboard.

Probably heat related. The card gets to a certain temperature, then dies.

or

I've seen similar crud on a laptop with a dying video card. A new
motherboard
fixed it until that, too, died.

Can you login from the machine remotely and look at xorg.0.log, dmesg, or any of the
users .x* files to see if there's anything
interesting there?
Kevin
That would be "login *to* the machine remotely".

Sounds like a graphics crash, whether that be a hardware problem, or a
driver fault.
The suggestions about cooling have merit, and it *might* be easy enough
to aim a fan at your card to see if it helps. If your graphics card has
its own fan, or cooling fins, it'd pay to check that they're in a good
condition.

I was given a card with a seized fan, and it runs fine for me, with a
case fan blowing air across the cards heatsink (with its own seized fan
removed). If anything, my jury-rigged solution cools the entire card
better than the original fan that just barely cooled one small part of
it.

And probably not work... The crosstalk between wires, the changes in
inductance and capacitance, would probably make a right mess out of the
whole bus, never mind the card on a cable extender.
Back in the ISA days, it wasn't unusual to see a daughterboard that
plugged a series of ISA cards into one socket. I've got an old
low-profile 486 PC that did that to place the cards parallel to the
motherboard. But that's a straight card, with simple track design,
inside the box, on a lower speed bus.
