I'm trying to figure out if the problem I'm having with XFCE is local configuration or more general. We usually run GNOME or ICEWM, and KDE seems to be installed by default. On one test workstation I'm trying out XFCE, or would be if I could get it to work. I basically did yum groupinstall xfce This completed. I rebooted the workstation and used the gear icon to switch from KDE to XFCE on my login. When I logged in, the wallpaper came up fine. The desktop icons and launcher blinked a few times, and then went away, leaving me with a mouse and a wallpaper. Logging in at the CLI as root gave me a notice to run abrt-cli list --since 1438605607 so I did: id e9c3ab355ae415d99e7b3c7ec308f60adae4c1f0 reason: wrapper killed by SIGTRAP time: Mon 03 Aug 2015 09:08:35 AM EDT cmdline: /usr/lib64/xfce4/panel/wrapper /usr/lib64/xfce4/panel/plugins/libactions.so 2 14680098 actions 'Action Buttons' 'Log out, lock or other system actions' '' uid: 1994 Directory: /var/spool/abrt/ccpp-2015-08-03-09:08:35-23138 Reported: cannot be reported id f875f7a88ea4fc44173f80d5ad1d35915224f5df reason: wrapper killed by SIGTRAP time: Mon 03 Aug 2015 09:08:35 AM EDT cmdline: /usr/lib64/xfce4/panel/wrapper /usr/lib64/xfce4/panel/plugins/libsystray.so 6 14680097 systray 'Notification Area' 'Area where notification icons appear' '' uid: 1994 Directory: /var/spool/abrt/ccpp-2015-08-03-09:08:35-23136 Reported: cannot be reported id 94c381491027f9eaef3ef9cdd993ac12ebdaec12 reason: xfdesktop killed by SIGSEGV time: Mon 03 Aug 2015 09:08:35 AM EDT cmdline: xfdesktop --display :1.0 --sm-client-id 282b012db-663e-4f98-8696-5992d1e4b880 uid: 1994 Directory: /var/spool/abrt/ccpp-2015-08-03-09:08:35-23163 Reported: cannot be reported id 19830963ababd77418bacf7a4e4a1538a3133b3d reason: xfce4-panel killed by SIGSEGV time: Mon 03 Aug 2015 09:08:34 AM EDT cmdline: xfce4-panel --display :1.0 --sm-client-id 2edda8ad9-738d-4a9b-a7b9-792dd6c1e6a2 uid: 1994 Directory: /var/spool/abrt/ccpp-2015-08-03-09:08:34-23131 Reported: cannot be reported id b90d98c9a1120a215adce7929b2196e3de3426c7 reason: wrapper killed by SIGTRAP time: Mon 03 Aug 2015 09:08:34 AM EDT cmdline: /usr/lib64/xfce4/panel/wrapper /usr/lib64/xfce4/panel/plugins/libactions.so 2 27263010 actions 'Action Buttons' 'Log out, lock or other system actions' '' uid: 1994 Directory: /var/spool/abrt/ccpp-2015-08-03-09:08:34-23112 Reported: cannot be reported id f6335de65e2286d905dfb72acf7b55f06fee2642 reason: xfdesktop killed by SIGSEGV time: Mon 03 Aug 2015 09:08:34 AM EDT cmdline: xfdesktop --display :1.0 --sm-client-id 282b012db-663e-4f98-8696-5992d1e4b880 uid: 1994 Directory: /var/spool/abrt/ccpp-2015-08-03-09:08:34-23135 Reported: cannot be reported And so on. I'm assuming this is in fact the xfce parts getting killed. So then I googled and my googlefu is apparently weak - I can find lots of instructions on installation such as: http://unix.stackexchange.com/questions/181503/how-to-install-desktop-environments-on-centos-7 and they all suggest echo "exec /usr/bin/xfce4-session" >> ~/.xinitrc so I've done that with no change I can tell. I believe the issue may have been my first run of XFCE was when my home directory was full. I have since cleaned it up, but cannot find a .xfce or anything obvious in my home directory to delete to "re-set" XFCE so it asks me to run initial setup again. I'm not at all sure how to debug further. -- James Pulver CLASSE Computer Group Cornell University
