I have attempted to get a misbehaving X windows system to restart
without rebooting the machine. In the past, as I recall,
ctrl-alt-backspace would do this. This evidently has been disabled with
the current X windows releases on Linux, including SL 6 . What is the
current equivalent (perhaps a shell command), or how does one reactivate
a control sequence to force the X server to exit and
restart/reinitialize, with a fresh login screen?
I have found some references using a web search to this issue for a
number of current Linux distributions, but none of the offered "cures"
seem to work with SL 6 (or presumably any RHEL 6 variant).
