-- Information about the crash:
Kubuntu Netbook Remix installed from usb. Installed on HP Mini 110-1000. everything seems ok, more or less. I was trying to get the newspaper look(plamoids side by side) but it is not working. Plasmoids taking entire length of screen. I enabled 4 desktops in order to use cube. Effects working ok. Wireless is good after installing proprietary drivers. Maximizing of window is good, but problem is all windows are maximized, even the ones that are supposed to be little. Mini has n280 chip and 2gb of ram. Hope you can pass any info. that you can not use forward to proper channels.
