I'm trying to use the DVI output on my GeForce3 Ti 200 with a refurbished ViewSonic VG171 LCD. After I messed around with the settings a bit, I got X working, displaying a beautiful, crisp picture. I am still annoyed by two serious problems -

1) When the screen blanker activates after 10 minutes, instead of getting a blank screen (or even better a suspended LCD) the screen displays some strange pattern of lines and boxes, apparently using colors from the images that were previously displayed. When I hit a key the display comes back flickering at 10 or 30 Hz. I have to power-off the panel and let it rest for a while before the flickering goes away. Scary!

2) I can't use the text console after the first time X is successfully started. My monitor just displays "OUT OF RANGE" on a black screen if I press ctrl-alt-F1. This makes debugging X a big pain.

Relevant configuration information is here: http://deconfusion.org/tmp/nv/

Any ideas? Anyone *not* having these problems? DVI support was the main reason I bought this card and it seems to be handled pretty badly in 3123.

Thanks

For 2), is the "rivafb" module loaded? It shouldn't be, check with lsmod.

I don't know about 1, but power management hasn't always been high on the list of features to get working right. Part of the problem is that not much of it is documented very well for the driver people to refer to, of course.

Nope, no rivafb. Just NVdriver. The README says not to use them together.

Right, that was why I was asking. Some people don't see that part of the README, and others read it but try it anyway.

Well, I don't really know then. Hmm.

I should have made it clear that I'm pretty sure this is a DVI problem. With analog out on a normal monitor I never had this problem.

Hmm, im using an 15" TFT monitor thru DVI from a Ti4200, and I have no problems with blank screens and such. It comes up as it should be from "standby".

31.23 complied from SRPMS
Redhat 8 with default kernel
GF4 Ti4200 (Leadtek)
