Subject: [Bug 117131] vga_switcheroo does not switch IGP -> DIS ( IGP == i915 , DIS == radeon )
Date: Tue, 26 Apr 2016 15:26:25 +0000 [thread overview]
Message-ID: <bug-117131-2300-oHwe65FfAD@https.bugzilla.kernel.org/> (raw)

--- Comment #18 from Jason Vas Dias <jason.vas.dias@gmail.com> ---
I think FGLRX is evidently able to run my laptop's display in
dual-driver mode whereby the Intel IGP card runs the LCD in some sort of
"slave" mode under the control of the fglrx Radeon 8970M controller module,
to display frames produced by the Radeon card.
It would be nice if Linux would either
A) fully support this configuration
OR
B) detect that this configuration is not supported and refuse
to attempt to go into graphics mode at all on the radeon card.
- this would include things like vga_switcheroo complaining
/ returning an error when asked to switch without a MUX .
Linux is evidently not doing either yet .
I'm not convinced the intel driver can "go it alone" either in this
scenario -
