Similar problem in Ubuntu 16.04.1 (Unity), with AMD APU (AMD A4-7210 APU with AMD Radeon R3 Graphics "MULLINS") + AMD GPU (AMD Radeon R5 M330) on a Lenovo Yoga 500-14ACL.
Everytime I launch a 3D game application with DRI_PRIME=1, the system hangs and returns to the lightdm login screen. I also tried to use a xubuntu session (installing xubuntu-core package) with xfwm or compton, but the problem persists. ** Tags added: xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1430888 Title: DRI_PRIME with radeon/intel windows do not draw To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1430888/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
