Ubuntu
linux package

Freezes of the environment for 5-10 seconds.

Asked by topgunbg

From time to time my ubuntu freezes and i can't select or click anything, sometimes the mouse is moving, sometimes it's not. It happens for 5-10 seconds. One of my friends has the same problem and we've spotted that it happens only with the newest kernels. Last year we used ubuntu 9.10, and we've had no problem, but now we do.
We both use the gnome environment with compiz.
I'm not sure what should i present you as log, but ask and i'll do it xD.

Hold shift at boot and select the memtest to make sure your RAM is healthy. If it is ok then let us know and we can continue diagnosing.

!offtopic it's ok but i do a tonne of IRC using AndChat which doesn't really lend itself to the small screen, specially on busses etc. 2.1 ROM

Try:

sudo nvidia-xconfig

Then reboot, may help

> happens only with the newest kernels

Reinstall nvidia driver and check if nvidia-common is installed.
If it still doesn't work with newest kernel, but with previous one, consider to report a regression against it.
Comment on nvidia.

Or
- try nouveau
- disable visual effects (compiz)

I purged all nvidia packages and then install them again. It works fine now.

Thank you, all! :)
