XScreenSaver in Solaris 10
It seems to be that XScreenSaver won’t load for regular users in Solaris 10 (update 6, 10/08) using JDS.
This means that a regular user can’t lock their workstation screen or have the screensaver come on. Typically, an error message along the lines of “XScreenSaver failed to load” pops up when the user logs in.
Pretty annoying all round.
Happily, it’s an easy fix. Edit your .profile and add /usr/openwin/bin to your $PATH variable.
Log out. When you log back in, you should see a “Lock Screen” option on your menu and screensavers should kick in.
