I am new to ubuntu so I don't know any information to provide to help me, so let me kno what you need.

When I am trying to connect to external display on my laptop, mirroring the display is hit or miss, sometime it will entirely except that launcher disappears. When I try to extend displays I get an error saying it can only support up to 2048X2048 pixels, is there any way to increase this limit, I know that when this laptop ran windows it could support higher resolutions than that. My laptop has a ATI Radeon X1250 video card.

Thanks for any help, and sorry for the lack of information.

Welcome to Ask Ubuntu! What driver are you using for your graphics card? Please provide the output of lspci -nnk | grep -iEA3 "(vga|graphics)". And does "Additional Drivers" list any additional drivers to install for your graphics card? –  gertvdijk Jan 30 '13 at 23:55
