Many of my applications stops working after upgrade from karmic to Lucid. First and very important GUI is not starting. It just drops me on CLi after throwing lots of error then i have to login via CLI then run STARTX to get the GUI. Tomboy is not working even i have tried with the diff user.

Thanks & Regards
