Comment 104 for bug 1310489

I can confirm this Bug is indeed the reason my 4 Desktop machines can't enable the second ATI graphics card. I made the "a)" changes mentioned here, <http://askubuntu.com/questions/453902/problem-in-setting-up-amd-dual-graphics-trinity-radeon-hd-7660g-and-thames-ra/477006#477006>, copied my xorg.conf file from my working 12.04.5 machine to the 14.04.1 HDD, deleted all the rest, and upon Boot both my Cards were enabled. Both cards appear in clinfo, and I can issue commands in aticonfig without receiving an Error. What other, if any, problems will this Edit create?

I suspect if my 4 machines are suffering from this Bug then it's very probable that many more are also effected. I'd hate to generalize, however, I would guess that Most machines running some version of 14.04 are effected. This week I downloaded and installed the latest version 14.04.3 and it too has this Bug with my machines.

It would be nice if this were fixed, and I could run kernel 3.13.xxx without having to make this Edit.
