hi.. gonna try to be accurate with this description.
my distro is a minimal one -zipslack, so I put by my own (with the invaluable help of the people here in lq) every single package containing all of the X11 and kde stuff.. and it works just fine..
with a little detail: the screen (when I run startx) is a little displaced to the right, about 1 - 2 cm. (that's maybe 10 px) so, when I trigger, 4 example, a web browser, I can't see the scroll bar. and, in the other hand, I've got a black vertical bar in the left side.
You'll think it's just matter of adjusting the monitor with its controls.. yes, I can do that, but it solves the problem..just for kde: when I go back to command line I cannot see the shell! -of course: it's displaced to the left... same think for windows. ..so: windows and bash shell are ok;
x11 and kde aren't.
does anybody know how to fix it? (from software I mean, not using the monitor's controls )
thanks in advance.

I had something similar happen to me once. The screen could be set up to be aligned OK for text mode, but the graphics would be screwy; or set up for the GUI to be OK, but then text mode went bang.

The problem was, my monitor was dying. Something inside had broken, and the settings could be adjusted for text or graphics, but not both.

If you have access to another monitor, see if the problem goes away with a different monitor.

The text mode has different resolution from the X screen. My monitor for example, remembers the positions for every resolution, beacuse every resolution uses different geometry. This means also I have first to set it up for every single resolution I use. I don't use software tools for this.

However you can try xvidtune (just type xvidtune in the command prompt in X). It allows you to move the image left/right/up/down. In windows your VC might have a tool for this (mine does)

Hey, iZvi ... you were right! your recipe fix the whole problem
(that xvidtune was new to me) ..just pressing a few times
the "move-to-the-left-the-damned-screen" button, and.. that's it!
thank U, pal.
