Looks like I lucked out on avoiding the blanking problem. I had an old
laptop that used s3-virge earlier and it bloomed instead of blanked.
Thanks for the additional information. I figured one vendor, similar
hardware.

This is the first real 2.6 kernel that I used. I'll have to get the
synaptic program and do the unzipping, ... installing, manual
configuration, as descried. The 2.6 kernel does seem a bit quicker. The
added work won't hold me back from FC2 final.
Thanks,
Jim
PS - Sorry Jason, I figured HP laptop = hp laptop. Does the blanking
problem happen at all resolutions on exit?
