Video Driver Problems

[chenriques]

Hi,

I've been using Ubuntu 13.04 for two weeks and it was running great.
Yesterday I had the stupid idea of installing nvidia-310 drivers and everything went bad.
I managed to access the terminal and I ran these commands to uninstall nvidia-310 and install nouveau:

sudo apt-get remove --purge nvidia-*
sudo rm /etc/X11/xorg.conf #if file does not exit is OK#
sudo apt-get install nvidia-common ubuntu-desktop
sudo apt-get install --reinstall xserver-xorg-video-nouveau
sudo dpkg-reconfigure xserver-xorg

After this my laptop was at least usable, my it's not like it was before the nvidia driver installation.
Mostly I have some mouse pointer flickering that is really annoying.

How can I configure Ubuntu video drivers like it was in the original setup?

PS: I'm in a laptop with Intel integrated HD4000 and a nVidia GT650M.

Thanks.

I think the problem is with my xorg.conf file.
Anyone knows the correct config?

I'm using the nouveau driver, nvidia GT650M, 1920x1080 resolution.

You do not need a xorg.conf file nowadays anymore.

For reference, installing the nvidia driver directly on an Optimus system is much more likely to result in borkage than 3D bliss. Here's how you do it (but PPA is not made for Raring yet, so don't do this now): https://wiki.ubuntu.com/Bumblebee

Can you post /var/log/Xorg.0.log ?

But the system is still processing this file, because if I change it's content something happens..

Before installing nvidia-310 (with RR fresh install) everything was working perfectly.
When I get back to home I'll post that file. Thanks.

I didn't say the system would not be using it.
It does use it, if it exists. And if there are errors in that file, the system will suffer.
But, the system will automatically detect drivers and use appropriate settings without the xorg.conf file too.

Attached Xorg.0.log (compressed in zip file).

It's using a generic frame-buffer driver when it should be using intel. Quite frankly, I'm not sure what you did to get it to behave like that. You did delete the /etc/X11/xorg.conf file, correct?

Also, is there a reason you're using Ubuntu 13.04? It would be a lot easier for you if you used Ubuntu 12.10 and followed the bumblebee instructions...

On my Lenovo laptop which I dual boot, I ended up disabling Optimus. Seems to be more trouble than its worth. Even Windows seems to be better off running the Nvidia driver all the time.

Running everything with the nvidia GPU will decrease battery life...
