12.04 login screen resolution wrong

[sebastian.s]

After i updated to 12.04 the resolution at the login screen is wrong, the resolution at login is to low. When i login to the desktop the resolution adjusts to the one i want. So how do i change the resolution for the login screen?

Thats normal. On login on most computers the resolution is not good. It should get fixed with some updates that should come in package manager.

So all i can do right now is to wait?

Section 9 worked for me.

It happened to me also, the problem is not grub starting, the problem is in the login screen (welcome screen) inside ubuntu, where usernames are, sessions, etc... It seems that login screen and inside my session have different screen resolutions, making impossible to switch from users because is hidden on one side of the screen...:(:confused:

Followed the steps but it's not working.

Running.


xrandr -q

I got this.


Screen 0: minimum 320 x 240, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 50.0* 51.0
1680x1050 52.0 53.0

512x384 89.0 90.0
400x300 91.0
320x240 92.0 93.0


So my script looked like this.


#!/bin/sh xrandr --output Screen-0 --primary --mode 1920x1080


The wrong resolution is not a big issue, but i would be nice to get it right. I don't like to give up! :D

@ sebastian.s

Shouldn't your output be "default"?

#!/bin/sh xrandr --output default --primary --mode 1920x1080

@ sebastian.s

Shouldn't your output be "default"?

#!/bin/sh xrandr --output default --primary --mode 1920x1080

My new script looks like this.


#!/bin/sh xrandr --output default --primary --mode 1920x1080

Still won't work.

[sebastian.s]

thought i would post an update on this problem, it sorted itself as soon as i upgraded to 12.10. I have no idea what was causing the problem but I'm glad it's fixed now :)

Should i mark this thread as solved now?

I've just been through this with a 13.04 install. http://www.ashwinraon.com/2012/05/how-to-change-lightdm-resolution-in-ubuntu/ does have the answer, but there is a slight error corrected in the comments below it. ie a missing newline after the interpreter directive so:

#!/bin/sh
xrandr --output default --primary --mode 1920x1080

would have worked. I added a --rate 75 to my xrandr line for the refresh.
But then after getting a beautiful login screen I found my own login was reverting back to 60Hz refresh.
The answer to that was in ~/.config/monitors.xml where I found a refresh of 60 specified and easily altered.
Finally - job done :)
