Eclipse doesn't shut down the process after exit

Another issue that I solved today was regarding closing Eclipse. After migrating to 64bit Ubuntu, my Eclipse (newly installed) didn't want to close. After closing, eclipse continued to run in background. In fact when I noticed it, I had 3 or 4 running eclipse processes since plugin installation requires restarts and each restart added one process eating all swap space. There was no evidence in GUI of running processes, but process manager did show them running. Then i came across this bug in launcpad and it did solve the problem.

Solution: Disable assistive technologies: System > Preferences > Assistive Technology Preferences > "Enable assistive technologies"

Dual monitors in LXDE

Trying out LXDE as my desktop environment on ubuntu box (Gnome is getting easy to use, but too heavy). There were some problems with dual monitor support (couldn't find a config app), but this line solved everyting:

xrandr --output VGA-0 --auto --left-of DVI-0
