I think there is another bug report very similar to this one, but can't find it for now.

As I mentioned on 1579481: The commit below (also from upstream) fixes this for me. Hadn't noticed the one mentioned above... I only cherry- picked this one on top of current xenial git source.

@ R.Becke I only did the update, nothing else. The system only has an APU, no discrete card. lspci output can be found in post #2 I do want to point out that your system has an additional error, which i can't remember to have seen on my system: "VCE init error (-110)" Perhaps you have a slightly different bug on your hands. If so it is probably smarter to open up a separate bug report, so it gets the attention it deserves. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573648 Title: 16.04 -> AMD APU via VGA gives blank screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573648/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1573648] Re: 16.04 -> AMD APU via VGA gives blank screen
The same happened to me. I did the upgrade 15.10->16.04 while my laptop was docked into the "HP 2013 UltraSlim-Dockingstation" and at some point during the upgrade my screen went black and so I decided to reboot. And from this point on I could not get my 16.04 system working anymore so I decided to do a 16.04 installation from scratch. Now I can at least work on my laptop standalone but as soon as I try to dock I get the exception in syslog shown above. The weird thing is that in the Display Manager dialog my external Acer Monitor is detected but no output gets displayed. One further "famous" error I get in syslog is: "radeon :03:00.0: VCE init error (-110)" - so hopefully this gets solved as well with the upgrade. Will try the kernel upgrade asap. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573648 Title: 16.04 -> AMD APU via VGA gives blank screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573648/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Dear Joseph, In response to your questions: The issue started after an upgrade from 15.10 to 16.04. The prior version of the kernel without the problem was the one from 15.10 (4.2.0-35) I will try to test as soon as possible. Some additional observations regarding this bug. * It is also present in the installation iso. * Booting via recovery mode partially fixes/circumvent it.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
