Description Levente Abrok 2017-02-04 17:43:53 UTC 
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.

Please attach the corresponding Xorg log file, and the output of the following from when the problem occurs:

* dmesg
* LIBGL_DEBUG=verbose glxinfo 2>&1
* LIBGL_DEBUG=verbose glxgears -info 2>&1

It might sound lame, but since then I haven't encountered the situation. Maybe it was an update or I don't really know.
For now, let's call this solved, hopefully it was truly something already fixed.
Sorry for wasting your time, but when I decided to report, it was really annoying and happened every 1-2 days.
