@Timo: No, it only hangs with amdgpu-pro. I initially tried changing to amdgpu and the issue went away. I also tried the current amdgpu-pro 17.10, which also fixed this issue. Unfortunately both drivers don't work as they should on my system, so installing them isn't a long-term solution for me. But yeah, the problem is definitely related to the amdgpu-pro drivers in version 16.40 (me) and 16.50 (Robert).
@LocutusOfBorg: I tried your ppa and could upgrade to libepoxy 1.3.1-1ubuntu1 without observing the black screen on boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1698233 Title: New libepoxy0 causes hang at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libepoxy/+bug/1698233/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
