Can't log into Desktop

[JoeS]

Using Debian Squeeze
Using KDE

I can't login to my Desktop. I type in my password and press Enter. The login screen goes away like the Desktop is loading and then it stops, and comes back to the login screen.

This is my xorg.conf

I tried to configure

Xorg: Xorg -configure

and got this message:

(EE) Failed to load /user/lib/xorg/modules/drivers/nvidia_drv.so
(EE) Failed to load module nvidia (loader failed, 7)
(++) Using config file: /root/xorg.conf.new
(==) Using system config directory /usr/share/X11/xorg.conf.d
(EE) [drm] No DRICreatePCIBusID symbol

Configuration failed

I was able to log into the Desktop, but lost it and don't know what happened. Thanks for any help in resolving this.

Did Package Manager upgrade kernel recently? Was it working fine earlier?
You have to re-install Graphics Card driver on every kernel upgrade. Try replacing "nv" with "vesa" in Section "Device" (Card0) of xorg.conf file.

Yes it was working. I don't know if I upgrade the kernel or not. I tried the vesa driver. Didn't work either. I reinstalled the nv driver; it didn't solve the problem. Why couldn't I reconfigure Xorg. I thought that might help, but it gave me error message?

Have you tried to rename xorg.conf file using mv command?

[Dapper Dan]

You may be going through what I just spent many hours trying to solve. Run:

X -version

Is it version 1.10.0? If so, there is an incompatibility with this latest version of xorg-server and most existing Nvidia 3d drivers. For me, the fix was to use NVIDIA-Linux-x86-270.30.run which is built for ABI 10. I hope this helps...

[JoeS]

I can't use the NVIDIA-Linux-x86-270.30.run. My Nvidia card is Vanta LT which is an old card; none of the drivers from Nvidia support it.

This is my X version:

X -version
X.Org X Server 1.7.7

        Before reporting problems, check http://wiki.x.org
        to make sure that you have the latest version.

Was the Package: xserver-xorg-video-nv upgraded; does it not work with Xorg or the Nvidia Vanta Lt card?
Thanks

Your xorg-server is not the latest so wouldn't be affected by this. Have you tried the Nvidia legacy drivers?
