Check your refresh rates: sounds like they're set low. Other than
that guess, you'll need to supply more info, for instance *which* Trident
and what sort of monitor.

1. Trident 9680 flicker

I installed XFree86 release 3.2 yesterday with a Trident 9680 card, and
I am getting a fair bit of flicker at 1280x1024 when I move the mouse.
It's not just regular flicker across the entire screen that you normally
get with a low refresh, but white lines flickering across the screen
while the mouse is moving.  Is this the result of slow RAM?  I have a
2 meg DRAM card.  Would and EDO card fix this?

There are other issues, actually.  I am running at a bus speed of 83MHz,
so the PCI bus is running at a little above 40MHz.  Would that be a
possible case?  My Diamond Viper works much better at a 75MHz bus speed,
but it refuses to boot with 83MHz, which is why I tried the Trident card
(perhaps not the best idea overall).

Any suggestions?

I don't necessarily want to get my machine working with the Trident card
at 83MHz, but I'd like to know what to look out for if I want to buy a
new video card.  Incidentally, the Trident card works fine in Windows
95 and NT at 83 MHz (and 1280x1024x256), so I am inclined to think that
it's not the bus speed that causes the flicker.

Any suggestions will be much appreciated.
