This question has been mentioned indirectly alot on the website, but there has always lacked:
- a complete solution
- an up-to-date approach
- a solution matching my situation (which might be common)
So the problem is that after installing the latest ati proprietary drivers following the steps given here and then opening up the catalyst center to setup the second monitor and rebooting, the second monitor appears blank with a X (or cross) instead of the mouse pointer. If I enable xinerama in the catalyst center I get a dual desktop but I lose all 3D acceleration effects and there other weird effects that bother me.
fglrxinfo in the terminal gives me this:
display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Radeon HD 5700 Series OpenGL version string: 4.2.11318 Compatibility Profile Context
display: :0 screen: 1 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Radeon HD 5700 Series OpenGL version string: 4.2.11318 Compatibility Profile Context
How do I get both the dual monitor setup and the 3D acceleration?
