I've managed to lock myself out of X. I need help!!

Ok well I was trying to get my mousewheel to work under X and tried to edit my X86config file. I did and managed to not be able to get back into X. All I can access is the window where you initialy log on. I tried typing startx but it just gives me an error. Is there anyway I can go change my X11/X86Config file back from this screen. I could try VI or Emacs but have no idea what to do. Maybe just a format and fresh install???

BTW the only thing I changed was mouse1 to mouse0 and then something at the bottom of the mouse input device section. I still have the old file saved in there on the desktop of X as root user.:smash:

If you have old config, no problem. Log as root. If you know exactly where your file is use
cp SOURCE /etc/X11/XF86Config-4
where source is the old config with its path.
If you don't know where is your old config, use
find / -name NAME
where NAME is the name the old config has. If there was no name change, it will be just
find / -name XF86Config-4
You'll get all XF86Config-4s there are in your system, so you can copy the right file beck to its place.

Good luck

Hey thanks for the help. I tried the find and all it found was the same file in /etc/X11 that is messing me up. When I firsted went to edit it as root in X I made a backup and put it on the desktop but it doesn't find that one. Also, when I went to edit it I noticed there was a file called XF86Config old. Can I use that?

I can't beleive all this headache just to get my mouse wheel to work. Never again.

Oh and one other thing. I think I renamed the file on the desktop to something other than XF86. Is there a way I can see what's on the desktop? Yeah I know I should have wrote it down but it's late and I'm and idiot.

That would depend on your window manager. If you do a "ls -al" in your "/root" dir (you did say it was on root's desktop?) you should see a ".<something>-desktop" dir. from there you should be able to hunt down your file.
Remember to log in as root or you won't see anything.

Is there not an old copy in the /etc/X11 directory?

Most editors will save a pre-edited copy of the original in the same directory? If you edited /etc/X11/XF86Config-4, try looking /etc/X11/~XF86Config-4 (or something). If it exists, then try copying it in place of the XF86Config-4 file (i.e. copy over the one without the tilde) and test.

Ok thanks for the replies I'm off to try again. Is there not a command that will like display all the files in a directory? Like say if I wanted to know what files are on the desktop of"root" then it would show like home,trash and then the file I saved there?


Woohoo success. I cd to the X11 directory then ls and it showed me all the files in there. There was a XF86Config-4~ so I just did a cp with that one over the one I changed and presto, I have X back. The greatest feeling is that I didn't let the machine beat me.

Ok so one last question. Is there a "safe" way to get a mousewheel working with KDE?

Thanks again for the replies.

well you "should" be able to use mouseconfig safely, but editing XF86Config-4 directly is ususally the clearest, easiest way to do it.

the basic wheel mouse config is

Section "InputDevice"

Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/psaux"
Option "Buttons" "5"
Option "ZAxisMapping" "4 5"


so you should only need to change (or add) the last two lines. just back up your file and edit it. i know linux can seem very flimsy and breakable at first, but you'l probably find that you'll see it as very robust. like that file controls X, if you screw it up, copy a backup over it, and it'll work.. bosh.

Yeah see I thought if the axis mapping was in there the button would work. Anyway here's what mine looks like

identifier mouse1
driver mouse
option protocol mousemanplusPS/2
option /dev/mouse
option zaxismapping 4 5

#chordmiddle is an option for 3 button logitech mice

#option chordmiddle

When I go to control center and then mouse, in the test area I can push the scroll button down and it works but in web pages it won't scroll the page up and down.
