I have just installed slackware 10.2 (please, do not start with 14.0, I beg), typed startx and, once in the GUI, I see neither the keyboard nor the mouse get any response. When the installer asked for me to choose a desktop environtent, I do not remember what I chose. Doing 'ps -e' I see an instance of xterm is running and, in the GUI, I can see a window with a prompt.
In the console where I ran startx, I see this message:
Could not init font path element /usr/X11R6/lib/X11/fonts/CID/, removing from list!
In /etc/X11/xinit/, I do not know how X chooses among the several xinitrc.* that there is there. Tell me if you need some console output to help find what is happening. I have no more elements of diagnostic for the moment.
