Comment 84 for bug 1068404

There are actually 2-3 issues in this bug:
a) There is the incompatibility between the fglrx and the intel
driver. In order to get around that, the workaround for now is to
patch the intel driver (reverting a commit)
b) The fglrx driver did not included some paths and this prevented
applications needing direct rendering from functioning
Both fixes are now included in my PPA.

Muxless hybrid systems with fglrx/intel drivers should work by now if
they select the dgpu.
For issues when using the igpu there is the separate Bug: #1088220

Personally, I have a muxless based on 6630M .

> @Nick: I noticed that Freedesktop's bug 56494 affects a system based on AMD Radeon HD 6550M which uses PowerXpress 3.0/Switchable graphics and not PowerXpress 4.0/Dynamic Switchable graphics. It is likely that the bug is not the same.
> To clarify the version of PowerXpress supported by the various supported AMD cards, I'll post this short list based on information on AMD site (names are based on information available on AMD site and on the slides which can be viewed on http://www.slideshare.net/AMD/amd-enduro-technology):

> PowerXpress 3.0/Switchable Graphics: HD 6300M series, HD 6500M series.
> PowerXpress 4.0/Dynamic Switchable Graphics: (HD 6300M series), HD 6400M series, HD 6600M/6700M series, HD 7300M series, HD 7400M series, HD 7500M/7600M series.
> PowerXpress 5.0/Enduro: HD 7700M series, HD 7800M series, HD 7900M series

> The HD 6300M series is reported as being based both on PowerXpress 3.0

> (http://www.amd.com/us/products/notebook/graphics/amd-radeon-6000m/amd-
> radeon-6300m/Pages/amd-radeon-6300m.aspx), we need to see the report of
> an user with a GPU based on HD 6300M series to clarify this (apparently
> the muxless version of PowerXpress 3.0 is not supported on Linux, so if
> a HD 6300M series GPU uses the muxless version of PowerXpress 3.0 it
> should have the same issue reported on bug 56494 of Freedesktop).
