Ubuntu upgrade to 9.04 Jaunty Jackalope

Finally upgraded to 9.04 Jaunty, here's some times might help:

1. ATI Technologies Inc RS480 [Radeon Xpress 200G Series] xorg-driver-fglrx is not supporting this card, so after upgrade, you have to manually remove fglrx packages:
dpkg -r fglrx-amdcccle xorg-driver-fglrx fglrx-modaliases fglrx-kernel-source xorg-driver-fglrx-dev
   after that, reconfigure xserver-xorg:
dpkg-reconfigure -phigh xserver-xorg
2. Root terminal is not working Here's the problem:
$ gksu /usr/bin/x-terminal-emulator Failed to contact the GConf daemon; exiting.
$ gksu -d /usr/bin/x-terminal-emulator No ask_pass set, using default! xauth: /tmp/libgksu-yesezF/.Xauthority STARTUP_ID: gksu/|usr|bin|x-terminal-emulator/5328-0-hkaihp_TIME1041381 cmd[0]: /usr/bin/sudo cmd[1]: -H cmd[2]: -S cmd[3]: -p cmd[4]: GNOME_SUDO_PASS cmd[5]: -u cmd[6]: root cmd[7]: -- cmd[8]: /usr/bin/x-terminal-emulator buffer: -Failed to contact the GConf daemon; exiting.- brute force GNOME_SUDO_PASS ended... No password prompt found; we'll assume we don't need a password. Failed to contact the GConf daemon; exiting.xauth: /tmp/libgksu-yesezF/.Xauthority xauth_env: /tmp/.gdmPSJQUU dir: /tmp/libgksu-yesezF
   I'm not a guru on GNOME or GConf, so here's how I solved it without changing anything:
   1. use xterm: change the command to gksu /usr/bin/xterm
   2. use xfce4-terminal gksu /usr/bin/xfce4-terminal
   You can also use other terminals of course. That just a lazy programmer's solution.
