Priority: medium Bug ID: 70409 Assignee: dri-devel@lists.freedesktop.org Summary: Radeon 7730M discrete GPU use crashes DRI PRIME, appears to be using r600 driver Severity: normal Classification: Unclassified OS: Linux (All) Reporter: calcprogrammer1@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
I am trying to get DRI PRIME working on my AMD dual-GPU laptop.
hp dv6z-7000 AMD A10-4600 APU with Radeon HD 7660G (ARUBA) AMD Radeon HD 7730M (VERDE) discrete GPU, 2GB VRAM Ubuntu GNOME 13.10 Custom-built kernel 3.11-rc7 from drm-next-3.13-wip branch (for DPM)
I'm using the Ubuntu-provided xorg, mesa, glamor, and libdrm packages. I had to compile my own xserver-xorg-video-ati/radeon packages with glamor acceleration support enabled. With this I can confirm glamor acceleration is being used with the 7660G on r600 and it works well.
Now, I want to enable DRI PRIME to use the 7730M with games.

When I run that third line, X crashes immediately with a segfault and automatically restarts GDM to the login screen. I will attach a Xorg log to this bug report after I post it and run the commands.
