"xrandr -s 1024x768" sets the resolution to 1024x768, but LCD display 
still shows 1280x1024 when I press its "Show info" button. Beamer 
doesn't work in that resolution.

Also, I can see black stripes (1 cm or so on a 19 inch LCD) below and 
above the image, where I can't move the mouse.

I think the problem lies somewhere else.
