Bug ID: 90355 Summary: DRI_PRIME+radeon+steam=problems + crash Product: Mesa Version: 10.5 Hardware: Other OS: All Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: higuita@gmx.net QA Contact: dri-devel@lists.freedesktop.org

I'm using ubuntu 15.04 on a thinkpad s440 laptop.

This laptop uses a Intel Haswel card and a AMD HD8670M and i'm the distro default mesa driver (10.5.2)

i' doing this to enable DRI_PRIME support:

xrandr --setprovideroffloadsink radeon Intel xcompmgr & DRI_PRIME=1 steam

please note that i'm using fluxbox and if i don't enble xcompmgr i don't seen anthing (DRI_PRIME=1 glxgears will only show up a "empty" windows, where with xcompmgr i can see the glxgears running)

So first problem is this, i require xcompmgr to enable DRI_PRIME. Also check this bug report: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1430888

If not dupe, i can open a new bug for this problem.

Anyway main problem...

A few seconds after starting steam i get a crash, with this dump:
