Version:           4.7 (using KDE 4.7.3) 
OS:                Linux

i have searched the bugzilla with "lock screen netbook workspace" keywords but it returned 0 results, so i'm posting the problem i have.

(in Kubuntu 11.10 32bit - KDE 4.7.3 Netbook workspace mode) Clicking the LOCK BUTTON(on-top-bar) to lock the screen does not work ; neither does right clicking(near widgets)+lock screen and ctrl+alt+L ; i found it strange and tried also other shortcuts like ctrl+esc to bring up the system activity.

None of these seemed to work for me, i'd like to specify that i encountered this problem on a very fresh install of kubuntu (both before & after updating the packages).

Checked the daemon for the keyshortcuts too and it was up and running.

As final test (in the same session) i have switched from netbook workspace mode to classic workspace and confirmed it was working perfectly in the classic workspace.

thus i think there should be some problem related to the netbook workspace mode that somehow hinibits these functions.
i'm currently using the classic workspace to avoid that.

i hope my report will be of any help to solve this for the sake of all :-)

Reproducible: Always

Steps to Reproduce:
1) fresh install kubuntu 11.10 32bit
2) log in with the netbook workspace mode
3) click the lock screen button on the top bar OR ctr+alt+L OR right click+lockscreen
4) screen lock does not work

Actual Results:  
it actually happens nothing at all

Expected Results:  
the screen should have locked

no additional information, very standard computer o.s. setup, out of the box
