hi

i want to make the KDE konsole transparent, but when i choose that option i only get a piece of my background in the konsole (it moves very slowy)
I want real transparency like in gnome.
Is that possible in KDE?

Mine works fine using KDE 3.4.2 though I am not sure if KDE uses real transparency. What graphics card are you using?

If i select the option i just get a piece of my background which moves very slowly

The transparency option in konsole is pseudo-transparency. It just makes the background translucent based on the desktop background wallpaper. It shouldn't move at all. When you move the konsole window around, it will periodically update the background, but not often enough to appear to be "motion". Pseudotransparency is all that's supported by konsole, and it does NOT require hardware graphics acceleration.

AFAIK, Gnome's terminal doesn't support transparency at all--true or otherwise.

With Xorg, the window manager can provide true transparent windows, but this isn't a function of the application software. This transparency essentially requires hardware graphics acceleration (otherwise, EVERYTHING becomes super sluggish).

Xorg's hardware accelerated transparency is very resource intensive, and is of limited usefulness since the entire contents of the window become semi-transparent, not just the background. In contrast, pseudotransparency like in konsole will have opaque foreground text over a semi-transparent background wallpaper.

Someday, true transparency will be supported on an application level, so you can get the best of both worlds (opaque foreground text/graphics over a true semi-transparent background). Don't hold your breath for this in GNOME. KDE will probably head in that direction.

but i have seen transparency in the gnome terminal! Very beautiful, in my KDE terminal it's just a piece of the background that moves very slowly ...
So it is only possible in gnome?

I really don't understand what you mean by "a piece of the background that moves very slowly". Your background shouldn't be moving at all. What do you mean? What does it look like if konsole is the only program on the screen? In other words, it should just be the background wallpaper (which does not move) and konsole (which isn't moving either).

Also, are you using KDE? Konsole is designed to be used with KDE. While it will run under other window managers, it may not render the background properly.

Hmm...now that I think about it, I used to have intermitent problems with konsole's background transparency where the tinting effect wouldn't work and the text was thus rendered pretty unreadable. I "solved" the problem by running another instance of konsole and closing the messed up one until I got one which was fine. I haven't had this problem pop up in a long time, though (not since I switched to Debian stable, at the very least).

i mean this:

i run KDE 3.4 and the latest Konsole.
If i set transparency on, then I move my konsole over my background to test the transparency. The only thing that happens is that the konsole "copies" a part of the background and sets this as background in the konsole. If i move the konsole the piece of background stays the same for some 3 seconds and then it copies again the part of the background where the konsole is located now. In gnome i saw transparency but i dont have that effect in kde ...

I am using KDE 3.4.2 and I don't have the sluggish response when moving or resizing konsole. Maybe you are using resource intensive apps and konsole is a bit slow as a result. As stated above, GNOME and KDE terminal emulators don't use real transparency, they just mimic it by taking a snapshot of your background every so often and updating it at certain intervals or when you move or resize them.
