However, I let the screen time out for a long time while I went checking for stuff. When I went to Ctrl-Alt-F1 to get back to command mode, a proper X display appeared. I rebooted (Had to power off owing to <a class="bz_bug_link bz_status_NEW " title="NEW - System fails to reboot after Ctrl-Alt-Del" href="show_bug.cgi?id=108464">Bug 108464</a>). This time I tried touching keys as soon as I noticed X had timed out but nothing would wake it up (like the "oddity" mentioned in <a href="show_bug.cgi?id=108577#c32">Comment 32</a>). Trying again, last time for tonight. Have taken the precaution of starting an xterm using my desktop's DISPLAY before starting X. Am following /var/log/debug (set up to log everything).
