Don't use xmodmap fix to Alt+Tab with RDP Clients
By ThinGuy on Jul 02, 2007
I've seen a few CAM scripts here and there that use the following command in order to fix an issue with Alt+Tab:
xmodmap -e "clear mod1"
This command is for only for CAM scripts that call the Citrix client, and only when using dtsession to send the alt+tab to windows rather than the local window manager (CDE) since the Solaris version of the ICA client does not have the option (yet) to grab the whole keyboard.
This command does bad things when used with the Sun Ray Connector for Windows or RDesktop (both of which do grab the whole keyboard) such as messing up normal alt+function key behaviors.
There really is no need to use dtsession for any full screen windows deployment, even if using xvkbd to lock the screen. See the following entry for more details on using xvkbd without dtsession.
