@Seth Forshee Is this what you're looking for? I'm using an HP ENVY 14 with a switchable graphics (Radeon HD5650 and integrated HD Intel graphics.)
I have attached a kern.log file with 3 boots: 1st boot - Bad. Black screen occurs on boot when trying to use Radeon driver without radeon.modeset=0 2nd boot - Good. Boot with radeon.modeset=0 3rd boot - Good. Blacklisted radeon driver. Booted using integrated intel driver ** Attachment added: "kern.log" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/727620/+attachment/2134375/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
