AfterStep in Android WebTop
Setting up WebTop environment
You have to have your phone rooted and SU installed. There are number of exploits and tools available depending on the phone.
It is recommended that you do not modify the WebTop environment in phone's own flash, but instead create a partition on SD card and use webtop2sd utility to copy phone's WebTop. webtop2sd will then mount this partition ontop of the phone's own stuff and if it get's screwed up you'll be able to go back to the blank slate and use your phone's WebTop again.
Get webtop2sd and instructions here.
In my experience running webtop configurator to install lxterminal did not work the first time. I had to reboot the phone one more time, and upon running webtop configurator again - lxterminal installed fine.
Package management is horribly broken in webtop due to manufacturers doing weird things to it, and possibly breaking it on purpose. To fix stuff, so that apt-get works again - use webtopscripts. Download from Google Code and follow the instructions. Setup script walks through all of the fixes - there is no need to run individual scripts.
After this you get Ubuntu Jaunty in more or less usable state. Time to install packages and tweak.
The first thing you want to do is disable (or possibly re-configure) xscreensaver. By default it will show nasty looking day-glo colored waves on the screen in colors that hurt eyes like acid. Open LXTerminal - (there should be a button for it on the dock at the bottom of the screen) and run <math>kill $(ps -ef | grep 5000 | grep xscreensaver | cut -c10-15)</math>.
