http://bugs.winehq.org/show_bug.cgi?id=59568 --- Comment #4 from Bernhard Übelacker <bernhardu@mailbox.org> --- I did a few tests. First the regular Linux desktop's Xauthority file is outside of the cygwin home directory. Unfortunately pointing the environment there did not work for me: $ wine 'c:\cygwin64\bin\bash.exe' --login -i -c \ "DISPLAY=:0 /usr/bin/xlogo" Error: Can't open display: :0 $ wine 'c:\cygwin64\bin\bash.exe' --login -i -c \ "DISPLAY=:0 XAUTHORITY=/cygdrive/z/home/benutzer/.Xauthority /usr/bin/xlogo" Error: Can't open display: :0 Therefore tried to go through the network path. But nowadays distributions may have by default the TCP port switched off. In my case for the slim login manager I switched it on this way: # nano /etc/slim.conf -xserver_arguments -nolisten tcp -deferglyphs 16 +xserver_arguments -deferglyphs 16 # systemctl stop slim # systemctl start slim Now the TCP port is open: # netstat -anp --tcp | grep -E "tcp.*$(pidof Xorg)" tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN 9941/Xorg tcp6 0 0 :::6000 :::* LISTEN 9941/Xorg And allow access to anyone (!): $ xhost + access control disabled, clients can connect from any host Now following worked for me: DISPLAY=:0 wine 'c:\cygwin64\bin\xlogo.exe' Therefore I guess this bug should be closed either worksforme or invalid? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
