I am the owner of an ACER Aspire TimelineX 3820 TG featuring a core i5-480M +
Radeon HD6550M.
Configuration (32 bits ONLY installation) :
- kernel 3.4.14
- glibc 2.14.1
- gcc 4.6.1
- Xorg 7.7 with xorg-server 1.12.1 / xf86-video-intel 2.20.10
- Slim 1.3.2
- fglrx 12.10 or 12.11 beta
X works fine with :
- the dGPU only ("discrete" selected in the bios)
- the IGP only ("switchable" selected in the bios and dGPU NOT declared in the
ServerLayout section).
X crashes at startup when :
- "switchable graphics" is selected in the bios
- only the dGPU is declared in the ServerLayout :

- both dGPU (Radeon HD 6550M) and iGPU (Core i5 IGP) are declared in the

Created attachment 69191
Xorg log when unsupported muxless platform is reported
Bug already reported to AMD, but since it seems to involve Intel driver, I thought it might be a good idea to report here as well.
Actually two similar bugs have been reported to AMD : ati.cchtml. com/show_ bug.cgi? id=634 (reported by me) ati.cchtml. com/show_ bug.cgi? id=580
