Using 4.4.0-24-generic from 16.04, I still have the issue. $ DRI_PRIME=1 glxgears
gives black screen and $ DRI_PRIME=1 glxinfo|grep "OpenGL renderer" OpenGL renderer string: Gallium 0.4 on AMD OLAND (DRM 2.43.0, LLVM 3.8.0) I have a Radeon R7 M265. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1581270 Title: Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on resume Status in xorg package in Ubuntu: Confirmed Bug description: dmesg shows issues with being able to use the discrete graphics card (relevant dmesg lines attached). Grub does pass "radeon.modeset=1" but it doesn't seem to make a difference. If I pass both "radeon.modeset=1" and "radeon.startpm=1"to the kernel, then it does not error (except for the VCE error -110, which is probably harmless). Running `DRI_PRIME=1 glxgears`: - with "radeon.modeset=1" and "radeon.startpm=1", no error but only a black window with a visible top bar. - with just "radeon.modeset=1", error (attached as 'glxgears'). Results are similar on Ubuntu GNOME 16.04, except with "radeon.modeset=1" and "radeon.startpm=1" set. It works, but lots of screen tearing. Attached are relevant dmesg lines, grep'd with 'drm'. I'll also be attaching entire contents of dmesg, /var/log/syslog, etc., but TLDR: [ 22.916285] [drm] ring test on 0 succeeded in 2 usecs [ 22.916289] [drm] ring test on 1 succeeded in 1 usecs [ 22.916292] [drm] ring test on 2 succeeded in 1 usecs [ 22.916299] [drm] ring test on 3 succeeded in 3 usecs [ 22.916304] [drm] ring test on 4 succeeded in 3 usecs [ 23.092271] [drm] ring test on 5 succeeded in 2 usecs [ 23.092276] [drm] UVD initialized successfully.
