No Intel HD driver after deleting Nvidia Optimus driver

[gronater]

Hi,

I'm currently running Ubuntu 12.04 and I'd like to disable my Nvidia 520M graphic card because it doesn't work well on Ubuntu as it is an Optimus card, but after I deleted my drivers for it my resolution is stuck at 640 x 480 and I can't get it to work properly on my Intel HD Graphics Family card.
How do I get this to work?

Can you run these commands in the terminal (Unity Dash -> Type in "Terminal") for me please?

cat /etc/X11/xorg.conf
lsmod

Your xorg.conf still uses the Nvidia config.

Perhaps

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

and restarting would help. (you could also kill lightdm, and start it again, .etc .etc)

I'm also running Ubuntu 12.04 with the nvidia gt 520m optimus graphics card. Gave me quite some trouble to make the graphics work after the installation. But it's working very good now with Bumblebee https://wiki.ubuntu.com/Bumblebee. It keeps the card turned off at startup. To use the card for an application is simple, just put "optirun" in front of the executing command (add it to the desktop launcher) and the card is activated. Saves a great deal of power too. To install it follow the link.
To see the nvidia config tool use

optirun nvidia-settings -c :8

BUT do NOT save anything in the default file, you'll mess up X11.
Use this path to save the settings

/etc/bumblebee/xorg.conf.nvidia

Test it

glxspheres
optirun glxspheres

@Marric

There is no need to add a bbswitch command to rc.local. The bbswitch module disables the nvidia GPU when not in use.
Also it is no problem to redirect nvidia-settings output to /etc/bumblebee/xorg.conf.nvidia since you have that option before saving changes to file.

[Marric]

Thanks, the startup script only makes sense when you use bbswitch standalone to turn off the graphics card without installing bumblebee.
Edited my last post.

Thanks for your replies!

The renaming of the xorg.conf to xorg.conf.bak worked! But when I try to run any program with optirun my screen turns black, although I can still use the pointer and the command line.

So I installed the nvidia driver:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get upgrade

but now I got a new error.

philip@philip-PC:~$ optirun glxgears
[   32.330568] [ERROR]Cannot access secondary GPU - error: Could not
load GPU driver

[   32.330613] [ERROR]Aborting because fallback start is disabled.
philip@philip-PC:~$ optirun nvidia-settings -c :8
[   58.982016] [ERROR]Cannot access secondary GPU - error: Could not
load GPU driver

[   58.982046] [ERROR]Aborting because fallback start is disabled.

Searched google, found this:

[ERROR]Cannot access secondary GPU
In some instances, running optirun will return:
[ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected.

[ERROR]Aborting because fallback start is disabled.
In this case, you will need to move the file /etc/X11/xorg.conf.d/20-intel.conf to somewhere else. Restart the bumblebeed daemon, and it should work.

It could be also necessary to comment the driver line in /etc/X11/xorg.conf.d/10-monitor.conf.

So I tried and I get this error:

philip@philip-PC:~$ sudo mv /etc/X11/xorg.conf.d/20-intel.conf
/etc/X11/xorg.conf.d/20-intel.conf.bak
[sudo] password for philip:
mv: cannot stat `/etc/X11/xorg.conf.d/20-intel.conf': No such file or directory

What am I doing wrong?

EDIT:

When try glxgears withouth optirun, I also get an error:

philip@philip-PC:~$ glxgears
Error: couldn't get an RGB, Double-buffered visual

Well, you said in your first post that you wanted IntelHD working. The way I did it - you can only use one or the other.

Lemme do a small explanation -

The xorg.conf controlls which display driver is loaded, and the monitor configuration, .etc .etc . By removing it, the nvidia driver stops loading because Ubuntu simply detects the intel card.

As a result, you have to generate a new xorg.conf to tell Ubuntu (Xorg actually), to load the nvidia driver.

You can do this by running

nvidia-xconfig

I don't know how to do the rest, because I never had, or will have hybrid graphics.

[Marric]

Make sure you really have those ppa's in your software sources:

 
ppa:bumblebee/stable
ppa:ubuntu-x-swat/x-updates

Update, upgrade and reboot.
Test.
Then try this

 sudo apt-get install nvidia-current

Reboot.
If still not working reinstall bumblebee.
