<pre>Only integrated graphics Intel works.
When running graphics applications with DRI_PRIME=1, this application or
segfault or show a black screen (sometimes playing a sound).
Sometimes, with some probability, this leads to crash Xorg.
In the logs there is nothing suspicious or any errors, only segfault.
I attached some logs, if this is not enough, then tell me which file or output
of which command I have to attach.
I want to either with DRI_PRIME=1 worked discrete graphics or worked all the
time only discrete graphics.
Is this possible on the open drivers with the latest software?
