@Timo Aaltonen (tjaalton): after reading your comment, I decided to install kernel 4.4.0-23.41, but it isn't available on the repo anymore, so I installed kernel 4.4.0-24 (if "that revert is already in the xenial kernel since Ubuntu-4.4.0-23.41", then installing kernel 4.4.0-24 shouldn't be a problem). Then I ran some tests and my system "froze". I had to press the power button of my laptop to shut it down (hardware power off).
First I executed "DRI_PRIME=1 glxgears" on the shell: all I got was a black screen. Then I executed "xscreensaver-demo" and previewed the "Molecule" screensaver, twice: at the first time, nothing happened (as usual. This is normal), but at the second time the screen locked and I had to use the "Ctrl Alt F1" combo to switch to TTYS1 and restart lightdm (with the command "sudo service lightdm restart"). Then I returned to TTYS7 (Ctrl Alt F7) and hit the "Power off" (software) button, but the system hanged, so I had to press the physical "power" button of my laptop. If someone builds some 4.4.X kernel with the "good commit" e9bef455af8eb0e837e179aab8988ae2649fd8d3 (mentioned in comment #33) applied/patched, I can test it and confirm if the bug is still there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1608042 Title: 64-bit XUbuntu 16.04 "Xenial" hybrid graphics (Intel + AMD): AMDGPU crashes / freezes / hangs entire system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1608042/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
