--start here --
I recently bought an nvidia gt520 1 GB graphics card. To my surprise it turned out to be a bit of a pain to actually get it working properly.
Sadly, we don't always document all the steps when trying to get something to work, but here's roughly what I remember.
The problem:
I plugged the nvidia gt520 into the pci express slot, connected the vga cable to the vga socket on the new graphics card and started my computer. My setup autostarts gdm3. Everything went fine -- the boot messages were flashing by as per normal, then gdm3 started. And got stuck. I experience two different types of hanging -- either just a black screen, or a black screen with a single cursor indicator (a single _ in the top left corner).
Logging in remotely (had ssh server running) and looking at top I could see that gdm3 was using up 50+% cpu power. Leaving the system for half an hour didn't allow for any progress.
Also, even when I did ctrl+alt+f1 to bring up tty1 I would be forcibly returned to tty7 over and over again. Trying to fix anything was thus difficult. After doing ctrl+alt+f1 a few times and being thrown around it would stop responding and strange symbols would appear on the screen when trying to use the keyboard.
One last piece of information: my onboard graphics is nvidia as well, but this probably isn't relevant.
Logging in remotely I tried using the excellent smxi / sgfxi scripts (http://smxi.org/) to install the proper graphics drivers. I tried nouveau, debian-nvidia and nvidia-current . I also tried just deleting /etc/X11/xorg.conf and hoping for the best
Diagnosis:
First I made sure gmd wasn't starting anymore so that the computer wouldn't hang and I'd be able to work in peace:
sudo vim /etc/default/grub
Then to make the changes take effect,
sudo update-grub
and reboot
Second I tried unloading any modules
sudo rmmod nouveau
sudo rmmod nvidia
I edited /etc/modules and commented out nvidia, and made sure nouveau was there. I also edited etc/modprobe.d/nvidia-kernel-common.conf and commented out blacklist nouveau.
I then tried installing the nouveu driver a last time
sudo sgfxi -N nouveau
and rebooted
After the reboot had completed dmesg| grep nouv gave me the clue I needed -- the drivers had failed to load! I don't remember what the exact message was, but it was all about failure.
Solution:
(also see first post below)
I removed the xorg.conf
sudo rm /etc/X11/xorg.conf
then
startx
The desktop started! But I found myself in fallback mode -- the graphics acceleration obviously wasn't working -- but that wasn't a surprise since the drivers had failed to load.
I then ran
sudo rmmod nouveau
sudo apt-get install nvidia-kernel-dkms nvidia-settings nvidia-smi nvidia-xconfig
sudo nvidia-xconfig
startx
It worked!
My autogenerated /etc/modprobe.d/nvidia-kernel-common.conf now looks like this again:
alias char-major-195* nvidia
options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44 NVreg_DeviceFileMode=0660
# To enable FastWrites and Sidebus addressing, uncomment these lines
# options nvidia NVreg_EnableAGPSBA=1
# options nvidia NVreg_EnableAGPFW=1
# see #580894
blacklist nouveau
Remember to remove any mention of nouveau in /etc/modules.
You can change your /etc/default/grub back to the way it was again to make gdm start again every time.
Edit: Reading between the lines it seems that Squeeze may not have the proper drivers available for GT520 -- binary installation using smxi might be a good idea in that case: http://forums.debian.net/viewtopic.php?f=17&t=72876
