Apologise if it has been raised before... A search for kde or kdm didn't seem to show anything related.
I installed 5.9 standard and 5.9 deluxe in a toshiba sattelite 2450-101 laptop (about 5 or 6 years old), with 256Mb Ram and a Pentium 4, 2.66GHz.
With both versions, kdm completely locks (after the nvidia driver logo shows up). The cursor doesn't blink, the buttons cannot be pressed, but the mouse moves!
Ctrl + Alt + F1 does not work, the keyboard seems completely unresponsive. Booting into textmode and doing startx goes into the desktop normally and it is working fine, so it seems to be a kdm problem.
Reinstalling kdm-small (the version in the 5.9 repo has 5.8 as a version... that's strange) makes it work, but with the 5.8 "looks".
Starting k3b makes the computer hang again, while the command line information tells me that it is drawing the main window. The main window does show up, together with the splash screen. The same thing happens: mouse moves, but no buttons can be pressed (even on the panel) and keyboard does not do anything (including Ctrl + Alt + Backspace).
Amarok gives an error about missing libkhtml (if I'm not mistaken).
Reinstalling k3b, amarok, and kdelibs, seems to solve the amarok problem, but not the k3b one (still crashes).
The same cd's have been used afterwards to install VL on two desktop computers and do not show any of these problems, and I checked the installation files during install.
Thank you very much!
