I have a dell optiplex gx 260 desktop box with Pentium 4 chip.
Installed 10.04 - same issue - random black screen freezes.
It is purely random, **but I have a way to reproduce it.**
Run the:
System > Admin > System Tests>
Check only the Video Tests checkbox and run through the series of tests.
For me this always crashes (6 times out of 6 attempts), but not at the same
point each time.
I've configured grub to boot the 2.6.22-21 kernel which seems to exhibit the
problem much less (2.6.22-23 is the killer for me)
In fact I'm not sure I've seen it happen on 2.6.22-21 at all.
If I run "lspci -vv" I see the following video card info:
...
Intel Corp 82845G/Gl[Brookdale-G] GE Chipset Integrated Graphics Device
Don't know if there is any other info I could provide to help get a
reproducible test case but perhaps others who have this problem could
run the Video Tests to see if it happens for them.
I've never tried to ssh into the box after a black scren
