Description Thomas Sailer 2011-11-14 16:57:21 UTC 
Description of problem:
The nouveau kernel module no longer recognizes a GeForce 7300GT card. When modprobing nouveau, the driver is loaded but is silent (no dmesg output). No /dev/dri/card0 or /dev/dri/controlD64 device node is created.

Version-Release number of selected component (if applicable):
kernel-3.1.0-7.fc16.x86_64
kernel-3.1.1-1.fc16.x86_64


How reproducible:
always

Steps to Reproduce:
1.rmmod nouveau
2.modprobe nouveau

  
Actual results:
nothing happens

Expected results:
some dmesg output, device nodes /dev/dri/card0 and /dev/dri/controlD64 created


Additional info:
It used to work throughout several fedora releases, including 14 and 15.

On the bright side, nv recognizes the card and drives the LC panel using its native resolution (1600x1200). This never worked so far, nv always chose a smaller resolution.

Can I see your dmesg output please.
Comment 3 Thomas Sailer 2011-11-15 11:33:00 UTC 
It turned out that the problem was the nomodeset kernel parameter. I added it in the fedora14 timeframe (because it wouldn't work otherwise). Removing it now makes nouveau work as expected.

Ah, that's pretty much what I was expecting  Glad to hear that nouveau works properly now without it :)

Thanks!
