NVidia driver crashes forever after Alt+PrtSc+K

[dragonheart]

Hi again,

I tried to install Nvidia drivers (to play a small game) from one tutorial who was saying after installation to restart the xserver, so i pressed Alt+PrtSc+K and the xserver returned to a resolution of 640x480.
I tried lots of things but i have no idea how to change back to the normal resolution i had.
Also i have no idea how to configure the nvidia drivers. :-[

Thanks in advance.

Hi,

I don't know why you have this problem. I use nvidia GT430 without problems. To install drivers :

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current nvidia-current-modaliases nvidia-settings

But before remove old drivers : sudo apt-get --purge remove nvidia-*

Then reboot and all was ok for me. To set screen size, go to menu>settings>settings manager>display.

so i pressed Alt+PrtSc+K

That "magic SysRq key" can be used to kill X and svgalib programs, not to restart!

Does anyone know how to properly configure Nvidia in /etc/X11/xorg.config?
The problem is that i installed the NVidia drivers but are not enabled! I have somehow to adjust xorg.config.
I tried sudo nvidia-xconfig and after that i made a reboot and the screen had a resolution of 640x480... Also i have to mention that if i install NVidia drivers through synaptics, compiz doesn't work. Somehow they are partially installed and creating a mess.
As a matter of fact if i run glxinfo in terminal it shows multiple errors and the most common of them is
