https://bugzilla.kernel.org/show_bug.cgi?id=153121 --- Comment #29 from Michel Dänzer <michel@xxxxxxxxxxx> --- (In reply to Kontantin Ivanov from comment #28) > DRI_PRIME=1 glxinfo | grep -i opengl | egrep -i '(version|renderer)' > > OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile [...] > DRI_PRIME=1 glxgears > > Running synchronized to the vertical refresh.

Presumably because Xorg couldn't initialize the Radeon GPU. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
