Boot up from the Manjaro install medium — USB stick, CD or DVD, whichever you have — in live mode. Then, open up a terminal and issue the following commands…
sudo su -
manjaro-chroot -a
After that, it depends on which path you wish to go. For removing the package ignore on the Nvidia driver, edit the file /etc/pacman.conf
and remove the ignore
line. You do this with nano
…
nano /etc/pacman.conf
You save the file with Ctrl+O followed by Enter, and you exit the editor again with Ctrl+X. After this, you need to update your system again…
pacman -Syu
Switching to nouveau
is a bit trickier, and I myself don’t really have any experience in that — I have an integrated Intel graphics processor — but I suspect that you should be able to get away with the following command…
mhwd --pci -r video-nvidia
… whereby you replace video-nvidia
by the correct driver package, because there are different versions, depending on the driver.
After removing the Nvidia driver, you have to install the Free/Open drivers, like so…
mhwd --pci --install video-linux video-modesetting
You’ll also have to remove any blacklist file for the nouveau
driver from /etc/modprobe.d/
.
Whichever option you choose, don’t forget to exit the chroot
environment again before rebooting. You can do this by typing…
exit
… at the command prompt or by pressing Ctrl+D on your keyboard.
Then, reboot and cross your fingers…
