I have an iMac with a ATI 2600 which runs with the proprietary driver. Since that day, the boot screen is not the nice one but a simple 800x600 textual screen.
Is there some way to set the resolution to 1920x1200? Is there a way to get the graphical screen back?
I use Ubuntu 10.10, but it was the same with Kubuntu 10.10 before.
