Public bug reported: I have just upgraded from 16.04 to 16.10. The installation has dm-crypt installed in the whole hard drive.
If I try to boot up the computer with kernel 4.8.0-26, most of the time (probably 9 out of 10) the computer gives a black screen instead of prompting for the dm-crypt passphrase. I try to remove "quiet splash" from grub (I can see the grub boot menu every time) but this does not help. Even I am lucky when the system prompts me for passphrase and the computer comes up successfully, the screen goes completely black again if the screen turns off once I idle the computer for a few minutes. The computer is still running (I can login to the computer remotely), just the screen becomes unavailable no matter what key I press. I still have the old kernel 4.4.0-45 from 16.04 installed and this kernel allows me to boot up the computer every time. My computer is a HP Elitebook 745 G3 notebook with AMD PRO A10-8700B R6 APU. Please let me know if I need to provide other information. ** Affects: xserver-xorg-video-amdgpu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637646 Title: Black screen when booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/1637646/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
