Lock Screen Button and Keyboard Shortcut?

I hope this is the right place to ask my quesiton.

I'm using RHEL 5 Desktop (no support subscription). I'm just trying out KDE for the first time. In Gnome, there is a nice little lock screen icon and it is possible ot make a keyboard shortcut to engage the password protected screensaver. I'm wondering how to create such a button in KDE on the main panel and how to make a similar shortcut.

The panel in RHEL's KDE was very Spartian. Only a RH menu and OO apps. I've not had any problems adding new apps to it. I just can't find the lock screen app to add to the panel.

Finding keyboard shortcuts was a little more difficult. The RH menu didn't have the kcontrol app anywhere on it. I had to google to find that that was the app to run to change keyboard shortcuts. However now that I've found out to do it, I don't see anything to engage the screensaver or lock the screen. Searching for screen only turns up only screenshots and make window full screen. Searching for lock comes up with lock session and block global shortcuts.

Hitting Ctrl+Alt+L does disable all input, however the stuff I'm working on remains visible to anyone who might pass by. This isn't going to work for me, since a lot of confidential info might be on my screen and only I should be looking at it.

Can anyone help?

Thanks in advance.

1. Right-click on the panel, select Add Applet to Panel and look for the Lock/Logout Buttons applet.

2. Ctrl+Alt+L turns the screen black and locks it. I don't know why you can still see your desktop contents.

Thanks for the info. I found the Lock/Logout Buttons applet. However the lock button does the same thing as Ctrl-Alt-L it just prevents input but keeps everything on my screen visible.

I think the problem might be screensaver related. I tried the "blank screen" screensaver and that did blank the screen. Testing all of the screensavers, the only ones that work are the ones not listed in a category. So anything listed undre OpenGL Screen Saver, Gadgets & Simulations, Fyling Things, Banners & Pictures, or Visit to Flatland, don't seem to work. Using the test button they seem to work fine, but when it comes to actual activation they don't. What could I be doing wrong?

Thanks

Probably this has to do something with graphic drivers, what video card do you have?

I've got an ATI Video Card ATI Radeon X1300 Series. I downloaded and installed the newest drivers right after I installed RHEL.

Try:

Source code

glxinfo | grep direct

to see if you have direct rendering

Sorry, but drivers are not installed correctly. Please refer to ati install guide (or google, which is better).
