Public bug reported: I ran into this bug on Xenial LTS which left xorg unable to start.
It was fixed upstream in 6.10.1, so when I installed the the hwe package, it worked just fine. Perhaps LTS needs to be updated to the hwe? This bug is particularly frustrating because xorg fails without an obvious problem. There wasn't much to search for, so it took me days before I happened across the bug report at netbsd.org. I'd say that makes for an even more compelling case to update the LTS package. What happens is that xorg immediately exits. Xorg.0.log shows a normal startup, finds a bunch of modes, and then exits with the message, "(EE) Screen(s) found, but none have a usable configuration." without any indication of modes being rejected. I tried all sorts of workarounds vaguely related to mode detection, but none of them would work. Here's the mailing list discussion surrounding the bug. The Xorg.0.log excerpts in the discussion were exactly what I saw here, so I'll just refer to that: http://gnats.netbsd.org/50599 Let me know if I need to use ubuntu-bug xserver-xorg-video-r128 Failed: xserver-xorg-video-r128_6.10.0-1build2 Works: xserver-xorg-video-r128-hwe-16.04_6.10.1-1~16.04.1 lsb_release -rd: Description: Ubuntu 16.04.2 LTS Release: 16.04 lspci -kv: 03:02.0 VGA compatible controller: Advanced Micro Devices, Inc.
