hybrid graphics

[Russel Winder]

Hi,

My Lenovo T500 boots with switchable graphics. This means both radeon and i915
driver are loaded. By default it seems the integrated (Intel) graphics are
used.

0:DIS: :DynOff:0000:01:00.0
1:IGD:+:Pwr:0000:00:02.0

By default ME TV tries to create a GL-based pipeline, but it crashes.  If I
boot the machine in either the integrated or discrete graphics modes
everything is fine.

Has anyone any experience of GStreamer GL pipelines in this selectable
situation?

I mishandled the test. :-)

The GL pipeline fails in integrated graphics mode (i915 driver), it only
actually works in discrete graphics mode (radeon driver).
