hi all. i've installed the nvidia drivers with success, but glx has this weird flicker problem. it's noticeable while running glxgears (which reports around 850 fps), and is highly noticeable in q3a (which i can't actually play as the game ALWAYS locks on one menu or another). in both glxgears and q3a, it appears as colored or garbled blocks or shapes that flicker randomly in the window. and immediately after it happens, quake locks up... sort of. it'll freeze for a minute or so, then pick up again for a second, then freeze again. at first i thought the problem was quake, and ran it while forcing per frame updates to kill the lag, and that solved my problem of it freezing immediately after loading, but now it's doing it again. i ran the nv_check script to confirm that i had installed the nvidia drivers properly and it gives me all green flags. i've posted the output of glxinfo in this post because, frankly, i have no clue what to make of it (though it appears okay to me).
for reference, i'm running slackware 9.1, kernel 2.4.22 on a 500mhz p3. vid card is an agp nvidia geforce2 mmx. any ideas?
