Hello, I bought a new flatscreen. Changed Horizontal and Vertical refresh in xorg.conf. Made a copy of the original in case of.. Reboot. Now I can't get back in. It hangs at X11. I thought I could 'cp' the old file back to /etc/X11/.. but no reaction; I'm stuck here. I need a way in. Slackware 10.2. Thanks. Gr.F.

By "hangs at X11" you mean...?
If you are at the console (black) screen, try ALT+(F2, F3)...one of them should pop up a console login.
Otherwise, ALT+CTRL+F1 should bring you *back* to the console, where you can try the above.
If not, there's always the cd you installed from, boot into rescue mode, copy the file back there.

Good luck.

Try <Alt>-<Ctrl>-<BkSp>
Should drop you out of X completely. Do your copy then try startx.

In case your computer is booting into runlevel 4 (the KDM or GDM graphical login manager) the way to force a switch to runlevel 3 (plain console) is to do the following when the computer boots:

* When LILO shows the boot menu, press <SHIFT> and then <TAB>

* Type the name of the label you want to boot into (usually this is "linux") followed by a space, followed by the digit "3"; then press enter

* This will cause the computer to boot into console (non-graphical) mode, enabling you to edit /etc/X11/xorg.conf and testing your changes by running X using the "startx" command... which in case of a "hang" you can always exit through "<CTRL> <ALT> <BackSpace>"

Hello Wildcat, yes, ALT+F6 gave me the console; so simple. With 'cp' I put the backup in '/etc/X11/' and REBOOT. Thanks.

Thanks to Wildcat22, Syg00 and Alien Bob for their 'input'. I'm back on the slack.
Gr. F.
