** Summary changed:
- Blank screen with only mouse pointer after mesa driver update; display does
not switch to tty7 upon lightdm start; Xorg.0.log quickly grows
+ Blank screen with only mouse pointer after 7.10 radeon driver update; display
does not switch to tty7 upon lightdm start;
This issue has a workaround:
Download 7.9 radeon driver Ubuntu package (xserver-xorg-video-radeon-
hwe-16.04_7.9.0-0ubuntu1~16.04.1_amd64.deb) from:
https://launchpad.net/ubuntu/xenial/amd64/xserver-xorg-video-radeon-
hwe-16.04/1:7.9.0-0ubuntu1~16.04.1
Execute the following on the downloaded
Line 3039 in the source can also cause the message:
if (flip_sync == FLIP_ASYNC) {
if (!drmmode_wait_vblank(crtc,
DRM_VBLANK_RELATIVE |
Okay, a little code inspection leads to one of these two function calls
failing at line 3062:
if (crtc == ref_crtc) {
if (drmmode_page_flip_target_absolute(pRADEONEnt,
drmmode_crtc,
I'll "gdb attach" the Xorg process next and see if I can't get some
runtime data.

I think something is hosed with the radeon driver in mesa 17.2.8, but I
can't find the 17.2.4 pkgs to roll back and test the theory. The 17.2.4
