This may seem like overkill, but I wanted two kiosks to be available on our
ltsp clients on different screens, one for a web browser kiosk, another for a
vmware view kiosk. The vmware view account is also required to be a member of
audio, pulse and pulse-access. We're using the VMWare Horizon View client
(VMware-Horizon-Client-3.5.0-2999900.x64.bundle) supporting PCOIP and USB
redirection - there may be some library dependencies to be installed and at
least one library soft link to create.
Add the following three (3) files to the LTSP server (they were copied from
/usr/share/ltsp/screen.d/kiosk and /usr/share/ltsp/kioskSession, respectively:
(1) /etc/ltsp/screen.d/vmware-view:
* All VIEW* environment variables can set in /var/lib/tftpboot/lts.conf.
* Added VIEW_MESSAGE for echoing a "Please wait"
* Add qoutes around the gecos data ,,, in the adduser line - it may work in the
script, but it doesn't always work from the command line.
* Add $VIEW_USER to the audio, pulse and pulse-access groups.
* Escaped quotation marks were added to pass VIEW_OPTIONS for su statement in
vmware-view (and the eval in vmware-view-Session) to work properly
