I have the problem that I installed (Ubuntu 12.05) the Nvidia CUDA drivers 285.05.33
and everything worked fine



but after an update of the kernel via the update manager



to



uname -v 

**Linux zfmgpu 3.2.0-24-generic #38-Ubuntu SMP Tue May 1 16:18:50 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux**


I have the problem that on boot I only see corrupted graphics. I tried to reinstall the driver (which builds the kernel module) which worked but -> I can only boot the new kernel and have lightdm start perfectly by setting "nomodeset" in the GRUB menu. Without this I see corrupted graphics output and it does not start.



What can I do to correct this? I am not a pro! I am a bit lost what I can do



Can somebody explain why I need this "nomodeset" which was previously also not in the grub menu...

Nouveau is a attempt to replace the NVIDIA obfuscated driver and put it in the kernel. No modeset tells the kernel, not to attempt to set the screenmode. Nouveau would have to do that. However, my experience with an NVIDIA 690 is that nouveau starts to panic at my card and the boot system hangs. A sign to me, that nouveau is still not mature, because the 690 has been around for a while now.



About the driver: nouveau is a kernel component that you can not deactivate through ' additional drivers / restricted drivers' because these drivers are the ones you use for X windows.



what I did, is I added NOMODESET in the list of kernel parameters in grub, permanently.
When the system boots the kernel checks this setting and reacts accordingly.



For Ubuntu 12.04 the setting is stored in /etc/default/grub . You add it to the line titled GRUB_CMDLINE_LINUX_DEFAULT. If the line says: 



GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"


you would change it to: 



GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"


After adding NOMODESET to this line you should run sudo update-grub to allow grub2 to see it the next time you boot.
