Ubuntu stuck in low resolution after UNinstalling / disabling NVidia drivers
Solution 1
Make sure your nouveau driver is not black-listed.
I had the same problem as you after installing the NVIDIA driver manually and removing it after not enjoying it.
You need to take a look in your /etc/modprobe.d folder. You may well find a file named something like "nvidia-installer-disable-nouveau.conf". You will need to be root to delete this so fire up a terminal and punch in:
sudo rm /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
Obviously change this to whatever your file is called, if different. After that reboot and you should be good to go! I didn't use the restricted driver installer though, I downloaded the driver straight from NVIDIA so the file may be different or the lines:
blacklist nouveau
options nouveau modeset=0
May well be in a different file, so have a nosey around the modprobe.d folder.
Hope that helps.
Solution 2
i've removed nvidia drivers and had the same low resolution on one of monitors. surprisingly it helped to delete /etc/X11/xorg.conf file.
Solution 3
if your laptop has another onboard vga, use it instead of nvidia card...
Use bumblebee to solve the problem... it will automatically diagnose and solve your probs.
steps: open terminat and type:
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia

Solution 4
I have a w510. unity(ubuntu 14.4) hangs intermittently.
I installed the bumblebee software and that made it worse.
Xorg would fail to start completely. I then tried a lot of things, installed nvidia-331
, reinstalled the nouveau driver(which was the initial issue with the intermittent hangs).
The solution above worked for me. It turns out, the bumblebee
stuff made a bumblebee.conf
file in /etc/modprobe.d/
which black listed nouveau and nvidia drivers. I removed the file, rebooted. then installed nvidia-331
, rebooted (a lightdm
would prbably do the trick too) and all is well again. :)
cheers

Tried the Nvidia driver, installed using the Additional Drivers panel. Didn't like it much; the CPU seemed to overheat more and the brightness controls stopped working. Also selecting a second display is a pain using that horrible NVidia settings thing.
So wanted to disabled it again.. problem is, UBuntu is then stuck in either 640x480 or 800x600 (second time I tried to install it back and then remove again).
How can I get this back the way it was? The original Ubuntu drivers worked just fine, allowing me to run Unity and games properly. I tried a xserver-xorg reconfigure but this didn't do anything. (No xorg.conf file either).
This is on a Lenovo Thinkpad T410i

Caesium over 12 yearsCan you check if your
xserver-xorg-video-nouveau
package is still installed? This is what it should be using (if not the NVidia binary driver).dpkg -l xserver-xorg-video-nouveau
should have a line at the end startingii
if it's installed. -
Han Cnx over 12 yearsThanks; this doesn't solve the problem. The Nouveau driver was still installed. To be sure I removed it using the --purge option and then installed it again. I get teh right resolution now but still I get random behavior of the display: flashes, flickering, random artifacts appearing and disappearing everywhere.
