Xmanager FAQ

Desktop environment (Gnome, KDE, CDE) is slow when started from Xstart

Desktop applications such as Gnome, KDE and CDE use windows management application to manage its application windows. When Xmanager is set to use 'local only' for window manager, it may cause conflict with the remote application's window manager settings and cause delays or fail to open properly. 

To avoid this, use Xconfig profile manager to set the window manager to 'Automatic' or 'Remote Only' mode.

It takes too long to login or logout from Gnome. How do I fix this?

Gnome uses Esound system to transfer sound data. If you access Gnome with Xmanager, Gnome requests Esound service to the X server (Xmanager) machine. If TCP 16001 is blocked on your PC, login/logout may take a while due to delay of handling sound service request.

Note: In Windows Vista, we do not recommend using Esound daemon of Gnome system because even if the port is open, access to the port is blocked unless there is a service daemon running on the port.

How to disable Esound daemon on Linux
  1. After login to Gnome, System-> Preferences -> Hardware -> Sound -> Sounds tab
  2. Unselect 'Enable software sound mixing (ESD)'
How to disable Esound dameon on Solaris
