Crashed, crashed, crashed. Exactly the same TQString::TQString(TQString const&)
as from your 2017-08-06 20:57 (UTC+0100) thread post every time? Are there no
logged clues in journalctl, dmesg, .xsession-errors, Xorg.0.log or elsewhere?

The PC I mentioned 2017-08-06 18:58 -0400 is i586. TDM works to login and get a
TDE session working, but if I try without TDM running via startx, startx gets
Xorg running, but it immediately terminates.

Which *tqt* packages are installed? Does anything among

look related?

If you log onto IRC irc://freenode/trinity-desktop maybe SlavekB could help more
than mere users here? trinity-devel list likewise at this point seems likely
better suited to actually solving your problem. Indicate exactly which NVidia
device you have. Better help may result from keeping the NVidia driver
uninstalled until the problem is resolved.

Another thought, since you're apparently not averse to reinstalling on a
separate HD: try a different TDE supported RPM distro, PCLinuxOS, CentOS,
openSUSE or Fedora. If no crash there, probably not a(n unsolvable) hardware issue.
