It may be time for you to ask for help from the devs, using the debian-devel mailing list or one of the freedesktop.org Xorg mailing lists, or by filing a Debian bug.
Yes, perhaps, if I can pluck up enough courage...
The problem has returned here. Xorg.0.log keeps terminating with an empty backtrace, and nothing in dmesg unless adding drm.debug= to cmdline. C-A-D doesn't do anything. openSUSE Tumbleweed still works. Nothing I can think of has changed overnight. Maybe this is come kind of timing issue, consistently bad for your machine, occasionally OK for mine.
Last night and this AM before my last post here I was reliably getting into Xorg after a lot of trial & lockups. So, a bug filing is apparently needed. I'd like you to file it. You're using XFCE4, so presumably only standard repos, while I'm using Trinity, meaning non-standard repos, plus having a related issue you haven't mentioned. TDM is trying to start even though the target is multi-user, so ATM at least I can't get a chance to even try startx.
Once you've filed and shared a bug I'll subscribe and add comments. Bug filing instructions I just used for an installation problem are here:
