Hello everyone.

I run Ubuntu 10.04 and once in a while I stumble upon the following error message on startup:

Ubuntu is running in low-graphics mode

The following error was encountered. You may need
to update your configuration to solve this.

(EE) NVIDIA: Failed to load the NVIDIA kernel module.
Please check your
(EE) NVIDIA:   system's kernel log for additional error
(EE) Failed to load module "nvidia" (module-specific error, 0)
(EE) No drivers available.
Reinstalling the driver does make it go away but only temporarily. After a while (2-3 weeks usually) the error gets back and it really bothers me to reinstall the driver every time. It's been happening for months now, regardless of the kernel I use or drivers version, and under no special circumstances. Any ideas as to what might go wrong here?

Thanks in advance.
