I have agp radeon HD 3450 graphic card. I've tried using proprietary driver but i couldn't do a bunch of stuff, movies stuck, etc.. Anyway now i use open source driver from ubuntu repositories, the one that is installed with system.

My problem is this. Resoluton of the screen that best fits me is 1152x644. But in monitor properties i can't set this resolition. Only 1024x768 and 1280x1024. I could set this in catalyst control panel with proprietary driver, but with this open source driver not.

Is there a way to set this resolution with radeon open driver?
