No graphics after update to 2010.12 KDE / Nvidia GS 8400 [SOLVED]

[rethymnon]

Hello everybody.

After an update yesterday my PCLOS with KDE 4 ( installed on April 2010 and constantly updated since ), the system does not boot into the graphic Desktop anymore, or at least, I can see a black screen only. But I can hear the introductory sound of KDE. Instead a see a terminal-like info : "Looking for new hardware........". That's it.

Trying a startx from a terminal shows the following output :

 " # startx
xauth: creating new authorityfile /root/ .serverauth.4534

Fatal server error:
Server is already active for display 0. If this server is no longer running, remove /tmp/.X0-lock and start again.

Please consult the X.Org Foundation support at  http://pclinuxos.com for help.

Invalid MIT-MAGIC-COOKIE-1 keyring giving up.

Xinit: Resource temporarily unavailable (errorno 11): unable to connect to X server

Xinit: No such process (errorno 3): server error.

The same result with a newly downloaded PCLOS 2010.12 KDE LiveCd. Only VESA works with a not acceptable Resolution.

The Nvidia video drivers are closed source drivers provided to the users of PCLinuxOS through a redistribution agreement with Nvidia Corporation. The latest drivers available from Nvidia are provided through our software repository. It appears to me that you have 3 options available at this time.

1. Upgrade your video card to one that works with the latest Nvidia drivers from Nvidia.

2. Post a bug report with Nvidia detailing the make, model and brand of your Video card in hopes a future driver update will be compatible with your video card.

3. Download and install an older working version of the driver from http://ftp.riken.go.jp/Linux/pclinuxos/apt/pclinuxos/2010/RPMS.nonfree/ Please remember there are two parts to this driver. The dkms-nvidia-current-xxxx package and the  x11-driver-video-nvidia-current-xxxx.

Good luck.

Hello everybody,

thanks to you all for your readiness to help me solve my problem.

The good news is, I fixed the problem yesterday with the help of a fellow German user from www.pclinuxosusers.de.

The solution was:

"apt-get remove --purge x11-driver-video-nvidia-current dkms-nvidia-current

apt-get install x11-driver-video-nvidia-current dkms-nvidia-current"

HURRAY !!!!

The strange thing is that I downloaded the freshly released PCLOS 2010.12 LiveCD and booting it always ends up with the same problem as with my installed system after Saturday's update.  
Something special with my hardware ? I don't understand that.

But I understand that nvidia is closed source and this is not the right place for such problems.

Anyway, thanks a lot for your help

The main culprit with the latest "x11-driver-video-nvidia-current 260.19.29-1" - package seems to be:

Enabling 3d-Desktop effects !!!!!!!!!!!!!!!!!!! This definitely ends up with a malfunction of my graphics ( see my original posting ).

Running "drakx11" in a Terminal, reconfiguring my graphics with DISABLING compositing ( 3D-effects ), then restarting the system, and almost everything goes well again, except for, you guess, those 3D-effects.....

And, by the way, I also tested this with LinuxMint 10. Downloading and installing the proprietary-drivers resulted in exactly the same problem: No graphics after a reboot....

Even trying to start the latest PCLOS 201.12 livecd ends up this way. "No input signal" on STRG-CTRL-F8 and of course a Konsole on STRG-CTRL-F1 !!
Is COMPOSITING enabled by default The only way to get started is with the VESA-drivers.

I wonder if this is just a problem with my GeForce 8400 GS or other Nvidia cards, too !?

Greetings and a really happy, succesful and healthy New Year to you all....

Hi, i have a GeForce 8400 GS but i have had no problems whatsoever either with the live cd or after installing, with and without 3D desktop effects.

Lots of posts elsewhere too mentioning some issues with the 8400 and newer drivers...not for nothing, but I noticed Newegg had a whole lot of them on sale cheap, another red flag.

It is a down dirty shame Nvidia makes graphic drivers that are not compatible with their video cards!

but where?    where?     where did i heard that before?

with another name on it...  ati!  that was     

honestly latest ati/amd seems better than nvidia, especially with this very old 8400 that should be perfectly supported, almost 2 years on sale

[rethymnon]

So, my hope is, the Nvidia people are going to fix the problems with an update anytime soon.....too much to hope ?
