On my laptop with Mdk 10.0 CE, when I run with the laptop panel I use a screen res of 1280x1024, when I use an external monitor I set it to 1600x1200 and switch off the internal panel (by closing the lid).

I change res using Xdrakres followed by a logout - not using kde's screen resize and rotate.

I have set KDE not to use a screensaver, and in my autostart folder I launch xscreensaver

well, xscreensaver runs using the "small" resolution - so covering just a rectangluare portion of the whole screen.

any clues ?

xscreensaver runs as a daemon in the back ground, it starts when you start the x server, which is before you log on.
Logging out/in wont restart the saver. To do that you are going to have to stop the xserver and restart it again.

Make your changes with Xdrakres.
log in a text terminal with su
init 3
init 5

which is a lot of messing just to get a screen saver working.
Personally I would just live with 1280 X 1024. works fine for my on my 20" monitor.

thanks MunterMan
the problem is the problem happens even if I (change res and) log out and do a ctrl-alt-bkspc which restarts X
and even if I (change res and) shut down the pc and restart !!!

basically, my xscreensaver NEVER ran at 1600x1200
so somewhere it reads a different screensize and uses that.

this is my /etc/X11/XF86Config-4 ... if that may help.
I notice that there is no mention of the defined modes in the screen section, just that 'virtual' ....

On my laptop, XScreenSaver doesn't fill the whole screen!


This is a bug in the X server, not xscreensaver: the XF86VidModeGetViewPort() function is full of lies, and I don't see any way to work around it.


I believe this only happens on certain laptops, and possibly only on systems that have a docking station or external monitor that runs in a different resolution than the laptop's screen.


There is discussion of this bug in the Red Hat and Debian bug systems; the buck was finally passed upstream to XFree86, where it is bug 421.


The XFree86 developers have closed the bug. As far as I can tell, their reason for this was, "this is an X server bug, but it's pretty hard to fix. Therefore, we are closing it."


So how about that. If you'd like them to actually fix this, you'll have to convince them that it matters, I guess...
