Problem with NVIDIA graphics driver: no login screen


[Log in to get rid of this advertisement]
I have a GForce FX 5200 128MB, but when I try to activate either of the installed drivers, after I restart, my login screen doesn't show up. I tried a few times Ctrl+Alt+F1 and them Ctrl+Alt+F7. It appeared and I could log in, but them the driver wasn't working. If I boot in recovery mode and try to fix the X server, the driver gets dis-activated and xorg.conf is reconfigurated as it was before driver activation.

I'm running Ubuntu 8.10 and I have an AMD Sempron 3100+ (1.8 GHz).
NVIDIA accelerated graphics driver versions are 173 and 96. The newer versions are not compatible with my graphics card.
I've searched a lot, tried to change some options in the xorg.conf file, but nothing worked.
I've also found that it could be related with the AGP, so I changed some options in the BIOS (setup), but with no results.
I don't think the problem is related to my GForce because when I was using windows, the driver was ok.

Here it's my current xorg.conf file:

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24Problem with NVIDIA graphics driver: no login screen
Option "AddARGBGLXVisuals" "True"
EndSection

Section "Module"
Load "dri"
Load "GLcore"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "nv"
EndSection

Please help me. Thanks.

Are you saying that the FOSS nv driver (the one referenced in your xorg.conf file, above) does not work, or just that replacing the nv with nvidia doesn't work? If it's the later problem, have you looked for a nVidia "legacy" driver in the "non-free" repositories? (As you remarked, the later nVidia drivers no longer support the old FX cards.)

My recollection is that the nv driver you're using includes the full functionality of the "official" nVidia driver for older cards, but doen;t support newer ones.

I think nv must be nvidia. Just change it and try again.

Well, it doesn't work when I replace the nv with nvidia.
I searched for other drivers in the repositories and I tried to install a version for older cards, though the installed version 173 I referenced, according to its description, supports GeForce FX 5200. I had the same problem with the earlier version.

Neither it works if I select and activate version 96 in System>Administration>Hardware Drivers (version 173 is recommended there).

Another thing I found was an error message in the text mode (after I tried again to activate the 173 driver and restarted):
* nvidia (173.14.12)...
/etc/rc2d/S20kde-guidance: 31: /usr/share/python-support/guidance-backends/displayconfig-hwprobe.py: not found

I'm not sure if it's related with the trouble, since I'm kind of new to Linux, but in fact the file doesn't exist.

Obs. Although I'm running Ubuntu, I have Kubuntu desktop installed (you might have noticed the "S20kde"), but the problem is not related with it, since it appeared before I installed Kubuntu desktop.

I finally found the solution for the problem! It was related with my graphics card. I've found it in a Brazilian forum. According to the post, GeForce FX 5200 has caused several trouble, but there is a simple solution: after the activation of the driver, it's necessary to edit xorg.conf (sudo gedit /etc/X11/xorg.conf) and and the following line:

PHP Code:
Section "Device"
    
Identifier     "nVidia Corporation NV34 [GeForce FX 5200]"
    
Driver         "nvidia"
    
Option         "NvAGP"     "1" #this line must be added
EndSection 
Here is the link, but it's in Portuguese: http://www.vivaolinux.com.br/dica/Re...eForce-FX-5200

Anyway, thanks for the info posted.
