I have an ATI Radeon HD 5770 graphics card in my computer. I want to install its driver in Ubuntu because I want to run Steam and play Team Fortress 2 while using Ubuntu without having to reboot my entire machine into Windows to do it. (I have 2 harddrives)
However, trying to install the drivers onto my Ubuntu system has been the worst yet from my history of using Ubuntu. If I install it, and it says it's complete, when I reboot the system, I get no Unity desktop. When I download the drivers from its offical site and run it in Terminal, I keep getting error messages saying in the picture below.
Any help will be thanked.
PS: I made an thread about what my next graphics card should be, it'll be an Nvida; This will be the last ATI card I buy.Screenshot from 2013-03-18 21:47:56.png
