Bug ID: 99679 Summary: DRI PRIME doesn't always work with intel/radeon Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: lev258@freemail.hu

Hello. I am running Ubuntu 16.04, with MATE installed later on it, using the latter currently. Beside normal system updates, I am using the Mesa stable ppa. Recently I started using DRI_PRIME=1 in some cases, to make the AMD videocard working. I found that it doesn't always work and the Intel one is used instead, like DRI_PRIME didn't even matter to it. This happens with Unigine Heaven, Steam and even glxinfo. Strangely, glxgears is not affected, it always does what it should be. I cannot reproduce this behaviour, it just happens sometimes. And it seems to solve itself after a reboot. Tell me, what you need to look into it. Thanks. 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
