Can't switch to Radeon rendering

[Guillermo Lo Coco]

After playing a lot, I can't swith from integrated Intel to Discrete Radeon VGA.

vgaswitcheroo:

0:DIS-Audio: :Off:0000:01:00.1
1:DIS: :DynOff:0000:01:00.0
2:IGD:+:Pwr:0000:00:02.0

If: "echo DIS > ...../switch" display turn off.
I tried make an script, switching to DIS and after launching a modified xorg.conf. But even that, none seem to happend. Screen still off.

GLXHEAD show rendering with INTEL instead of discrete Radeon:
root@labPC:/tmp# glxheads
glxheads: exercise multiple GLX connections (any key = exit)
Usage:
  glxheads xdisplayname ...
Example:
  glxheads :0 mars:0 venus:1
Name: :0
  Display: 0x1302010
  Window: 0x4400003
  Context: 0x13134f0
  GL_VERSION: 2.1 Mesa 10.3.2
  GL_VENDOR: Intel Open Source Technology Center
  GL_RENDERER: Mesa DRI Intel(R) Ironlake Mobile

Any openGL rendering app run slow.

My question is, How can I enable Discrete Radeon GPU ?

Thanks in advance!

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 failed: No such file or directory"

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 http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1406222

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.

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 message:
"intel_do_flush_locked failed: No such file or directory"

Recently added "LIBGL_ALWAYS_SOFTWARE=1" variable and seems to launch Bricscad in 3D.

I will 3D test more with this laptop. If something new appear, I will write here.

[Guillermo Lo Coco (glococo)]

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.

[penalvch (penalvch)]

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

[Guillermo Lo Coco (glococo)]

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.

[penalvch (penalvch)]

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?

[Guillermo Lo Coco (glococo)]

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.
