dude.. this is wrong.. just reinstall the drivers of intel:
$ sudo apt-get remove xserver-xorg-video-intel
$ sudo apt-get install xserver-xorg-video-intel
the problem is that when u remove the nvidia drivers.. the files in
/usr/lib/xorg/modules/ are removed... but if you reinstall the intel driver it will copy the files back again and everything will be fine! :)
(https://launchpad.net/~bumblebee i am now using bumblebee for using the nvidia card whenever i want, and it works very fine! :D )
if you want to try again to install bumblebee, first we have to remove any old crap you may still have installed:
$ sudo apt-get --purge remove ironhide bumblebee
(check out this issue: I can't uninstall Ironhide, or install any other packages)
after successfully removing this packages we have to make sure nouveau driver is blacklisted to do that:
we add the text:
blacklist nouveau
to the file
/etc/modprobe.d/blacklist.conf
to open the file do
$ sudo gedit /etc/modprobe.d/blacklist.conf
now we edit the file:
/etc/default/grub
We look for the line that says:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
and we change it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash rdblacklist=nouveau"
OK! now we have no nouveau anymore :D epic win!! now we have to install the nvidia proprietary drivers
$ sudo apt-get install nvidia-current
(I'm not 100% sure about it, because i installed it using the additional drivers tool!! )
ok, now we have everything set up for installing bumblebee.
first we add the ppa of bumblebee
$ sudo ppa-purge ppa:mj-casalogic/bumblebee
then
$ sudo apt-get update && sudo apt-get install bumblebee
after this... we can check if everything is setup by running:
$ glxgears
this will use the intel HD card... but if you add optirun before the command it will use the nvidia card
$ optirun glxgears
good luck!
