It sounds like hardware. You might like to test the video card in a
different machine, or test a different video card in the one in question.
Or maybe re-seat it.
Chances are, of course, that it’s onboard. But i’ve got no way of knowing
that, as you haven’t provided any information about your setup at all.

It seems hardly likely to be hardware as the Mandriva bootup sequence
displays perfectly. It is only when it switches to X that the problem
As it happens I use pluggable drive caddies. I shall plug in another drive
and boot on that. That should prove whether it is the hardware.
Unfortunately, I shall be unable to do that until tomorrow. Thanks for your

Not sure what that is but when I press “CTRL ALT -” or “CTRL ALT +” that
changes the resolution one of them shifts the display left about 3″ so
you may have inadvertently done that. All it does is change the screen
If its not broke must be Linux

Why do you say this?
Changing the screen resolution generally changes the frequency at which
the display must run!
This can cause the display to be shifted.
Unless you have a REALLY unusual monitor, it MUST compensate for this.
Because computers will use a few different resolutions — one for the
splash screen, another for X, another when running Planet Penguin
full-screen — monitors can record settings for each resolution separately.
It sounds like the monitor is set correctly for the splash screen, but
not for your X settings.
Alan secker 2012-08-05 23:56:52
Because the controls can only handle up to around a centimetre.
I believe i used the wrong term by saying ‘Splash screen’. I meant the image
that sits under the text that scrolls up if one presses ESC during boot-up.
Whereas the same term is also used for the KDE start up graphic. The screen
is filled by the former but not by the latter.
As I have said elsewhere, by unplugging the Mandriva drive and plugging in
one currently holding PCLinuxOS (I didn’t rate it), KDE comes up perfectly
so it isn’t the hardware anyway.
I have tried # Xorg -configure.
xvidtune told me I was trying to go too far.
CTRL-ALT-Minus made all the icons bigger (and the resolution lower). KDE was
now larger than the screen but did use all of it
If the X-Server uses different frequencies, I would love to know the name of
the configuration file that holds it.
It is a puzzle.

Try running the command krandrtray, which adds a icon to your system tray,
which allows to select the resolution, and for resolutions that support it,
the refresh rate frequency.

Did you video driver or monitor get accidently changed?
I get about a 1/2″ off-center difference between Nvidia free and
Nvidia proprietary driver when the desktop loads, I’ve seen it
happen when my driver got switched for whatever reason.
The screen is centered OK during boot process until X starts and video
driver loads and that’s when the screen went off-center.
It seems like I had a lockup and had to reset and on the reboot the
video driver switched back to open source driver and I started seeing
what it sounds like your seeing.

Well of course it can still be hardware. I’ve had any number of systems
go through the boot cycle with Mandriva, Ubuntu, DSL (or pick one) only to
c*** out at the desktop because of buggy drivers or incompatible
hardware. Some information about your affected system might help.

No it wasn’t, it was the driver. I uninstalled the ATi driver and downloaded
and installed the the latest ATi proprieory driver for my Radeon X300SE.
After rebooting not only did kde fill the screen again but my webcam images
could now display on kdetv!
Thank you everyone for some great info. Bound to come in useful in the

I don’t know what replies you have received so far but xvidtune may give
you some idea of what your screen is doing. It also allows you to move
the screen and then print out the ModeLine for your x config. I know it
looks pretty ghastly and comes with a fatalistic warning 🙂
