Muxless video card

[makoto]

I have dual video card in my laptop, Intel HD 3000 and ATI Radeon HD 6630M. Intel video card is the integrated one, which works well. However, ATI video card is discrete, and I fail to make it work in TCL. Although I know it is possible to switch two video cards by editing xorg.conf, it is said that this method is only useful for MUX cards. My ATI video card is muxless, which means it can only render, and its output needs integrated video card. I have read a post in gentoo forum and the author solved the problem by starting two X servers. But I failed in that method. The second server is definitely started, and glxinfo can give the information of the ATI card if I specify the display parameter. But it cannot render, just consuming power. Can anyone resolve? I heard that nVidia muxless card can be solved by bumblebee, while there is no solutions to ATI so far.

I gather you do not want to, or have not tried the closed src driver from AMD allegedly such a beast exists when I went to AMD site. I suspect this site is commercial so I can't link to it under forum rules, but I guess you know how to find it eh?

AMD Catalyst™ 13.4 Proprietary Linux x86 Display Driver   116 MB   13.4      4/24/2013

However I noticed a number of links to some forums around that AMD site appear to be broken so I can't link to them.

I have not tried to build a closed src driver under TC so not sure if the xserver is at the right version.

Others will know I am sure

good luck
