Bug ID: 108030 Summary: Does not work discrete graphics CERAR (6370M) Product: Mesa Version: 18.1 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: ilya@ilya.pp.ua QA Contact: dri-devel@lists.freedesktop.org

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?
