Ubuntu: Stuck at 800 x 600


Today there was updates for my Ubuntu 16.04 (x64).

The updates were installed and it asked me to reboot.

After reboot I was unable to log into the graphic environment. It just looped to the login screen (Not the first time I have this problem)

After doing these steps:

service lightdm stop  sudo su -  cd /usr/local/bin  wget -Nc smxi.org/sgfxi  chmod +x sgfxi  sgfxi  

I was able to login into graphic but I am stuck at 800 x 600. I was in 1080p before the update.

Please help.


Just had a little similar issue. For some reason it was not blacklisting the nouveau drivers. Remember to install the nvidia drivers before doing this.

Try this:

cd /etc/modprobe.d  ls  

Now look if there is an nvidia or nouveau file there, if not:

sudo nano /etc/modprobe.d/blacklist.conf  

paste this at the bottom of the file:

blacklist vga16fb  blacklist nouveau  blacklist rivafb  blacklist nvidiafb  blacklist rivatv  

Save with Ctrl+X and press Y to save.

Now run:

update-initramfs -u  sudo reboot  

See if that works.


I want to apologies in advance but this might not be accepted as an answer.

I was not able to fix that problem. I want to add that I got a similar issue when I upgraded from 15.04 to 15.10.

In both case I was unable to boot all the way to the GUI and ended up burning a DVD and re-installing from scratch.

When I install from scratch the resolution is correct and I can boot into the GUI using the Nvidia driver.
