**Table of Contents** [[!toc ]]
If you have problems with [[Cygwin/X|CygwinX]] then you can try to find a solution on this page. Much more is covered in the [[FAQ|http://x.cygwin.com/docs/faq/cygwin-x-faq.html]] but the sections here will be filled in the next weeks.
If you have found a solution to a problem, feel free to add it to the appropriate section.
# General
## Installation
### cygX11-6.dll not found after installation or upgrade
Reinstall the `xorg-x11-bin-dlls` package. Make sure not to reinstall any `XFree-*` packages. Check if `/usr/X11R6/bin/cygX11-6.dll` does exist. Check if `$PATH` contains `/usr/X11R6/bin`.
## Clipboard
## Keyboard
If your keyboard layout is not configured correctly (eg you only get the us layout) please contact [[the Cygwin/X mailinglist|mailto:cygwin-xfree@cygwin.com]] and send your `/tmp/XWin.log` or at least the lines similar to these:
[[!format txt """
(--) winConfigKeyboard - Layout: "00010407" (00010407)
(--) Using preset keyboard for "German (Germany, IBM)" (10407), type "4"
"""]]
With this information it is possible to add that entry to the list of known keyboard layouts. If you already know which is the correct XKB layout code for your layout please state it in the mail. This will make things quite easy me.
## Cygwin/X Startup
### Cygwin/X freezes right after startup
Zone Alarm (esp version 5) was reported to break Cygwin/X. Check the log file. The last line will say something about keyboard layouts. remove Zone Alarm to get rid of this.
make sure /tmp is mounted in binmode
### Duplicate invocation error
Most likely you have started XWin twice with startxwin.bat or startx or a similar script. You can't do this. You can only start XWin once. If you want another terminal window (which in fact is just a convenient side effect of running startxwin.bat) you should do this by starting `xterm` from the cygwin shell or from the startmenu entries.
### Multiple Users, Multiple XWin
If you want to start XWin multiple times, you have to assign each of them a unique display number eg `XWin :0 $OPTIONS` (this is the default) or `XWin :1 $OPTIONS`.
If you start XWin with different users and get access proplems in `/tmp/.X11-unix` then disable the unix sockets connection scheme by starting the xserver with `XWin -nolisten unix $OPTIONS`. The `$DISPLAY` variable `:0.0` will not work anymore but can be replaced with `localhost:0.0`.
### The root window is not shown when starting XWin
This is a small problem with run.exe. If you start XWin with -nodecoration, -multiwindow or -fullscreen the window will come up normally.
## Appearance
### X as default pointer in multiwindow mode
To workaround this add the command `run xsetroot -cursor''name left''ptr -fg white -bg black` to `startxwin.bat`
## XTerm
### Resizing XTerm does not change linewidth in bash
Try starting *resize*. See [[mail|http://cygwin.com/ml/cygwin-xfree/2004-05/msg00171.html]] for details.
## Networking
### Personal Firewalls
[[Cygwin/X|CygwinX]] requires properly working TCP/IP even for local connections. It listens on port 6000 + display number (eg. 6002 for display :2.0). If you use the internal clipboard manager or the multiwindow feature it creates network connections even if no other client is connected.
If you are running a personal firewall make sure you set a rule which allows XWin.exe to connect to the port and a rule which allows it to accept connections on the port.
If you are still experiencing problems try disabling the Personal Firewall.
#### Zone Alarm
There have been reports that programs are experiencing network problems when running [[Cygwin/X|CygwinX]] with Zone Alarm installed. This is because cygwin creates a new socket everytime select is called and the Zone Alarm networking stack will then kill connections which are already running on that port.
# Remote Usage
## SSH X11 Forwarding
### Programs report strange errors
See [[FAQ Entry|http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-ssh-no-x11forwarding]]
## Cygwin/X reports AUDIT: client 1 rejected from IP ''remotehost''
By default remote connections are not allowed (security). You can work around this by either of:
1. add `-ac` to your Xwin.exe arguments (e.g. in `\cygwin\bin\startxwin.bat`)
1. use the xhost program (you may need to run cygwin setup to install it) to allow access.
1. `xhost +` to allow all hosts
1. `xhost +yourappserver` to allow just clients on _yourappserver_.
If you're using XDMCP then the problem may be wrong DNS resolution. Make sure your windows host has a hostname which is valid from linux too and an IP address which linux can resolve to that hostname.
If you add a line
`192.168.26.1 myhost`
to `/etc/hosts` on the XDMCP server containing the IP address and the hostname of your windows host the name resolution should work.
## Unix flavours
### Keys or mouse buttons not working on AIX, SUN Solaris, HPUX
Disable NumLock. Some programs treat NumLock as a modifier like Control.
A small program which will do this is available [[here|http://cygwin.com/ml/cygwin-xfree/2004-04/msg00307.html]]
### No keyboard input in Java
Disable NumLock. Same problem as above.
### Mouse buttons not working in Motif applications on SUN Solaris
This is a bug in the Motif libraries from SUN. See [[details|http://support.wrq.com/techdocs/1717.html]]. There is a patch available from SUN: :[[Patch 108940|http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fpatches/108940]].
