I'm having a video display problem with my monitor. It's
an old Gateway VX700, purchased 11/1999. My graphics card
is an Nvidia GeForce 6100, purchased around 2006. Both
Until recently, my computer was a dual boot,
with Slackware64 13.1 and Windows XP.
For the first year of the dual boot system, there was no
problem. Then I think I botched up my system in someway,
trying to update, and had to reinstall software packages.
That's when the display problems started. I fiddled
around with it a month or so, to no avail. The problem
manifested while running xscreensaver; at some point, the
monitor would freeze up, displaying horizontal or diagonal
lines of different colors. I had to turn off the computer
to unfreeze it. I never had the display problem in XP,
although I rarely ever used it anyway.
I recently installed Slackware 14.0 as a single boot system.
The problem remains, although on two occasions, the monitor
freeze has occurred while on the internet.
The horiz/vert settings are exactly as specified in the
monitor's user guide. At this stage, I think it is either
the monitor or graphics card, with a weak possibility that
it's a software problem. I would like to narrow it down
to the exact problem, rather than start buying hardware to
rule out possibilities. Any help greatly appreciated!
