I've done some googling, and have read (and experienced) about the bug
with kcheckpass in kde 4. I'm currently have version 4.3.1 installed,
snv b121. I've found notes at <a href="http://techbase.kde.org/Projects/KDE_on_Solaris/OpenSolaris/Status#Broken_screen_lock" target="_blank">http://techbase.kde.org/Projects/KDE_on_Solaris/OpenSolaris/Status#Broken_screen_lock</a>.
I've navigated to the location to make the configuration changes
suggested, however I'm not seeing the appropriate options to change.
Could someone please elaborate on how their configuring kde to invoke
xlock, instead of kcheckpass? I'm currently invoking xlock via command
line, until I resolve this issue.
