Redraw problems with Twinview GeForce FX 5200

guardian653 · 07-16-2004, 10:43 PM

Hey, I hope someone here at LinuxQuestions will be able to solve this problem... I tried...

Alright, my basic setup is Slackware 10 with Xorg. I'm using the NVidia 1.0-5336 drivers because their latest (1.0-6106) doesn't support TV-out with the res 1024x768. I use the TwinView setup to get a clone image of my main monitor to my TV. I got TV-out working, but theres a catch.. when TwinView is enabled, windows do not properly redraw themselves. For example when I work in gnome-terminal, the becomes unreadable unless I move the window offscreen. Or when I maximize Totem (or better yet full screen it) I get part of the old window next to the video (say I have a video and there are bars at the side, when I maximize it with TwinView on, instead of getting black spaces I get part of the window, once again this can be cleared by moving the window off screen).

Anyone have a solution to this problem?

Review specs:
Slackware 10
Xorg
Using TwinView to Clone the one monitor to the next (in my case: Monitor -> TV)
Using NVidia driver: 1.0-5336

My xorg.conf:

I don't have an nVidia card, nor do I use Dual Head/Twin View, so I could be completely wrong, but if your second "monitor" is a television, these settings do not seem correct. Aren't there special settings for a TV?

They are considered generic settings for a TV as stated in the NVIDIA docs. 60 Hz is the same setting used in Windows with TwinView.

The problem is that windows don't properly redraw themselves when resize or "update" (e.g. make output in gnome-terminal going really fast)

I was able to get a screenshot of one of the redraw problems....

Anyone got a idea how to fix this?
