loss of window controls

[klaus2008]

I think that you should try to start the window manager openbox in a command line. Open a terminal and issue

/usr/bin/openbox &

If there is already a window manager running, you will get an error message. Otherwise you should get the controls.

You might also try control-alt-backspace.

In any event, I would like to know what conditions caused your problem.
Please keep us informed.

Since you have a backup, you might try to see if just a
reboot solves a temporary X problem. It's your call on this.

<span style="background-color: #99FF99;">Tried the reboot both warn and cold. no effect. i did notice that the comp-z splash screen no longer appears during the boot up process. I believe that that may be the root cause (pardon the pun) of the failure. If so, how do I get comp-z working again?</span>

Tired both ideas. The first one gave the error message and said that a manager is urnning; the second appeared to restart xorg, but still left off the window controls. If I can't resolve this in a few days, I will erase the USB drive that my Knoppix runs off of and reload it from the CD. Hoping that 6.4 comes out in a DVD format first.

Hello, again, railrider1972.

We don't have many clues to help you with.
Did your USB ever work right? When was this? (K!6.4.4 came out in Feb 2011)
Did you make a copy of knoppix-data before things went bad?
Do you know how to rejuvenate your set-up using knoppix-data?
What were you doing when things went from good to bad (if ever)?
Where does your DVD comment fit here, anyway?
