I'm installing Ubuntu for the second time. The first time I got frustrated and installed Windows over it :)
Follwing advice I read here I followed the instruction on the following page to install ATI graphics drivers for the 780G integrated graphics:
http://wiki.cchtml.com/index.php/Ubuntu_Gutsy_Installation_Guide
After I did this I had two problems.
1) I have connected an analog LCD monitor with resolution 1024x768. After installation of Ubuntu but before installation of the ATI drivers, Ubuntu only allowed a screen size of 800x600 (or smaller). After installing the drivers the screen was fritzed, like it was using a resolution the monitor couldn't handle. I had to take the machine to a monitor with a DVI input, and that worked fine and auto-detected the resolution.
Question 1: How do I prevent it from doing this? I want to use the 1024x768 monitor. After installation of the ATI drivers I'd like the screen resolution to be no more than 1024x768. It can be less, and I'll work on fixing it, but I need to be able to see it.
2) A 3D application (Second Life) told me I did not have the minimum spec to run and the display strobed (flashed quickly). I suspect I did not have 3D acceleration enabled.
Question 2: How do I enable 3D acceleration once I've installed the drivers? And is there a simple way to test it?
Thank you kindly,
Amy
