Kubuntu 6.06 is most suited for the Acer 2428 laptop but Ubuntu 6.10 live gives a gnome crash error on run but still loads the desktop very slowly. However on clicking 'Install' it just shows non-stop HDD activity and does nothing. The lappy has to be forced shut-down. The same CD works and installs very fast on my PC which is older than the laptop and I am currently using this system. In both cases the distros come from the same company. Again, in Kubuntu 5.10, I was able to play VCDs after installing win32 codecs.
Did you make a swap partition before loading the live CD?? It makes the whole process a hell lost faster! Maybe your PC has a swap partition from a previous linux install.
