Ubuntu – Fix resolution on Ubuntu 12.04 (1440×900)

resolution

I'm pretty new to Ubuntu and I'm trying to get the correct resolution on my monitor. I have Ubuntu 12.04 so it has xorg 7.5 which is not supported by ATI anymore for my ATI Radeon Xpress 200 graphics as far as I can tell. I was told to go to the software center and download ATI binary X.Org driver, so I did that and it gave me a couple more resolution options, but none of them are the correct 1440×900 resolution of my monitor. Is there any way to get the correct resolution to show up?!

Xorg works with the blob driver and the ATI OSS driver.

To list your available resolutions check xrandr.

Your maximum resolution is determined by the card, not the monitor.

Ubuntu – Ubuntu 12.04 is changing resolution / refresh rate after login

This is with my experience :

I've installed Ubuntu and other distros on my macbook 6,1 many times and ran into the same issue.

I always have to edit the /etc/default/grub file to account for resolution.

Once you update grub and reboot, the resolution seems to stay where you want it.

Screen Resolution – Can’t Find Optimal Screen Resolution

Try first to define a VIRTUAL1 display:

xrandr --newmode "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync

And use it to set the profile of VGA-1:

xrandr --addmode VGA-1 1440x900_60.00
