Okay, I got rid of the Nvidia card. The drivers were so cranky I couldn't put up with it anymore. I got a nice Radeon 9000, and DRI is enabled. Looks great.

However, there is still an issue that I thought was tied to the Nvidia card: the screen twitches -- that is, for just an instant, the display shrinks a millimeter of two on all sides, then jumps back up to full size. I'm certain it's not the hardware, because it never happened while I was running SUSE 9.0, nor 8.2.

Does anyone know of anything that would cause this sort of thing? Running 4.9, BTW. If this keeps up, I'll have to do something different. It really breaks my concentration when I'm trying to write, and writing is my job (such as it is). Help me solve this or I have to go back to SuSE (not 9.0; it was kinda messed up).

My monitors twitch like that right before they die. It may also be something wrong in your XF86Config - make sure the Linemodes are appropriate for your monitor/video card.

I have strong doubts the monitor is dying; it's almost new. Not unheard of, just very unlikely. As for modelines: I don't have any --

[code:1:c420679563]
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
[/code:1:c420679563]


I have the modes listed, but never use anything except the obvious default. The monitor specs are right out of the book for the hardware:


[code:1:c420679563]
Section "Monitor"
Identifier "Monitor0"
HorizSync 30.0 - 95.0
VertRefresh 50.0 - 120.0
EndSection
[/code:1:c420679563]

Any other possibilities?

Try turning your vertical refresh down. You don't even need it that high for 1600x1200. Give 50 - 90 a shot.

Thanks, but no help. I suppose it's something in the way FreeBSD relates to 3D. At any rate, I'm running Mandrake 9.2 and the twitching is vastly reduced, both in incidence (only during the first few minutes after "wake up"), happens rarely, and much smaller in size.

But I'm not going anywhere. I'm still a fan of BSD, and if I ever get different hardware (mobo mostly) I'll run it again. For now I'm working on a set of tutorials on spammer-chasing.
