May 15th, 2018, 01:22 PM
Hi! i've just instaled xubuntu 16.04 and it works perfect but there is a problem with the display resolution. It only show me default option and the only screen resolution available is 640x480 73Hz but before installing xubuntu i tried it and the screen resolution was the original for my screen 1280x1024 60Hz.

Note: I'm actually using xubuntu 18.04 and there is still the problem.

Have you tried going into Settings -> Additional Drivers to see if it finds anything?

Are you using xserver-xorg-video-openchrome driver ?

im not sure.. How to see it?

I solved it!! thanks dino99.

The driver wasn't installed so i did this in terminal:

sudo add-apt-repository ppa:xorg-edgers/ppa

sudo apt-get install xserver-xorg-video-openchrome

Then Reboot and it detects my Screen!
