Hi Christopher, I'm running kernel 3.19 + oibaf ppa (https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers)
Beside that, I added DRI_PRIME=1 variable to /etc/enviroment to make it default. Even with that variable, latest kernel+mesa+, Bricscad fail to inicialize in 3D with this ugly message: "intel_do_flush_locked failed: No such file or directory" Recently added "LIBGL_ALWAYS_SOFTWARE=1" variable and seems to launch Bricscad in 3D. I will 3D test more with this laptop. If something new appear, I will write here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1406222 Title: Can't switch to Radeon rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1406222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
