Hi Christopher,
Exactly, if I force with vgaswitcheroo to DIScrete (radeon), display goes off.
I think, since it is a muxless system, Radeon GPU have no populated display
port. Only works as gpu coprocessor.

Guillermo Lo Coco, would you have an option in BIOS allowing the use of
only the AMD card?

Title:
Can't switch to Radeon rendering
Status in xorg
Hi Chris,
No option. Running latest Bios.
I think this muxless config is like a rendering coprocesor with no pin
to external display. Radeon coprocess data and use DMA to Intel FB to
connect to display. Something new for me.

Guillermo Lo Coco, while I don't consider myself a vgaswitcharoo expert,
as per https://help.ubuntu.com/community/HybridGraphics muxless systems
are not supported for it. Would this coincide with your research of
this?

Hi Christopher,
I'm running kernel 3.19 + oibaf ppa
(https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers)
Beside that, I added DRI_PRIME=1 variable to /etc/enviroment to make it
default.
Even with that variable, latest kernel+mesa+, Bricscad fail to inicialize in 3D
with this ugly
I was trying to draw some 3D objects with Bricscad in 3D and was
useless. Fail after few minutes (in the best cases) with segmentation
fault.
So I launch Kicad/pcbnew to check if something has improved in 3D
rendering, and seems to faster nothing.

Guillermo Lo Coco, could you please provide the full computer model as
noted on the sticker of the computer itself (not from the Bug
Description)?

Guillermo Lo Coco, this bug was reported a while ago and there hasn't
been any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
I found that my notebook HP G62 is a Muxless GPU system, with an IGP
i915 + DIS Radeon 54xx.
The way I can run an app in accelerated mode is with DRI_PRIME=1
glxgears
But I cannot enable it by default.
Also an important app for me fail to start with this silly message:
intel_do_flush_locked
12 matches
