# Ubuntu – Screen resolution stuck at 1024×768

display-resolutionintel graphics

I just updated from Ubuntu 10.10 to 11.04 and have an issue regarding the screen resolution. I have Intel integrated gfx chip and my monitor supports resolutions larger than 1024×768. (in 10.10 I've been using 1280×1024) But as soon as I upgraded, I'm stuck with 1024×768 resolution and seems I can't change it. running

xrandr

In terminal yields the following results,

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096

v: height 1024 start 1027 end 1034 total 1063           clock   59.9Hz


What maybe the problem? Is it a bug? What kind of steps I should take in order to get a higher resolution? (changing xorg.conf maybe?) Any insight is highly appreciated. Thanks in advance.

UPDATE

Screenshot after running

xrandr --addmode VGA1 1360x768

As you can see, side bar is not completely visible and Ubuntu logo at the task bar is missing. Also when you open an application, the Task bar of the application (where it should go to the top panel) is missing as well..

• I solved the problem by running:

xrandr --addmode VGA1 1366x768


I also added new modes to the change resolution drop down by using,

xrandr --newmode "mode line"


Where mode line replaces the supported resolutions. You can find the supported resolutions by running:

xrandr


Currently, it's working all right.
