Citrix: Freeze at Logout

Symptom

A user tries to log out from a Citrix session but the session does not respond.

Example: Once you connect to a Citrix session, everything works. After having reconnected and disconnected several times, you log out. The window freezes while the logout screen is shown.

Solution

Workaround

As a less recommended alternative, you can configure a hotkey to force a logout in such situations. Note, however, that this workaround can cause issues with hung sessions on the Citrix servers.

To configure a logout hotkey:

  1. In IGEL Setup, go to System > Firmware Customization > Custom Application. 

  2. Click  10966.png to create a new Custom Application and name it e.g. "Kill Citrix Sessions".

  3. Disable all Starting Methods for this session.

  4. Enable Hotkey.

  5. Choose e.g. Ctrl|Alt as Modifiers and define C (for "Citrix) as Key.

  6. Go to System > Firmware Customization > Custom Application > Kill Citrix Sessions > Settings.

  7. Enter an Icon name.

  8. Enter /tmp/kill_citrix as Command.

  9. Go to System > Firmware Customization > Custom Commands > Desktop. 

  10. In the field Desktop initialization enter following command in one line: 
    echo -e "#! /bin/bash\n\nps -eo comm,pid | grep ^wfica | while read c p tail; do echo \$p; done | xargs -r kill -TERM" >/tmp/kill_citrix; chmod 755 /tmp/kill_citrix

  11. Click Apply and reboot the device.

To configure the hotkey for a group of devices, you can alternatively create a profile or use this one: Unknown Attachment.
