I have Backtrack 5R2 KDE. The error resulted from a hard-reset (hard-reboot). After that, I cannot load the KDE manager when I enter the startx command after logging in.
Whenever I do a startx command (as root), the result resembles the following:
This is not the actual output (I just drew this with MS paint because I cannot do a printscreen). The screen is just black with the icon in the upper left corner. The other pop-up menu appears when left-clicking the mouse.
I tried the
cp xorg.conf.failsafe xorg.conf advice from other websites with no luck.
I have also tried the 'reconfigure option(s)' form the recovery mode with no success.
