DVI to LCD does not work without nvidia Driver

flysideways · 02-24-2005, 12:47 AM

OK, so I finally got an LCD monitor and using the DVI connection on my FX5200 is giving me fits. With the monitor connected to the DVI port all I get is a blank screen when X starts in FC3. It works fine in a virtual console for the command line. Booting the computer with Knoppix, X works. I spent a bit of time flailing about in xorg.conf with no luck. Finally I broke down and tainted my kernel with that nvidia driver, but......

Any ideas?

When I installed the Nvidia driver the only changes that I made to xorg.conf were to comment out Load "dri" and changed driver to "nvidia" and it worked.

Thanks.

Arg!!!! Now it doesn't reboot!!

Well, reducing the resolution in xorg.conf to a maximum of 1024x768 in 16 or 24 bits gets it booting with the "nv" driver.

Must sort out the proprietary driver booting issue. It would be best if I could figure out how to get the "nv" driver up to my monitor's native resolution of 1600x1200

An update, thanks to ilikejam in another thread, I figured out that the nvidia module was not loading during boot. I did an lsmod and it was not there. X starts after doing modprobe nvidia. I edited /etc/rc.d/rc.local and added modprobe nvidia and now X comes up with the nvidia driver during boot. It's nice to have the native resolution with the DVI connection. Now, if I could only figure out how to get that without the proprietary driver.

Cheers.

Hi,

Would you mind posting your config file (XF86Config or whatever)? It might help me with a similar problem.

Thanks,
Mike

I'm using the the analog input now so that I can use my kvm switch. I never did get the nv driver up to the 1600x1200 resolution through the dvi connector, the nvidia driver worked though.

Cheers.
