Ubuntu 11.10

Tips
- Use Alt left click to move the screen around to expose the offscreen buttons.
- Use Ctl Alt T to open a terminal
- xterm is under dash home - System
- Important At login time - select the gear and choose 2D - This will clear up display problems. Otherwixe on 12.04 mouse clicks won't work and it with eventually die with a Compiz closed unexpectedly.

Install from Scratch
Mount /usr
The 702 has only 8GM of SSD. As shown above the ROS Installation Hydro, 3.8G is used in /usr. The result is 86% disk usage. Here, /usr in moved to an SD card and mounted at boot. Warning - mistakes can result in an un-bootable system.
Don't start the display manager (dm) at the login window . Instead <CTL> <ALT> <F1> to initiate a terminal. As a result, there will be a less likelyhood of any dependencies on /usr.
sudo is in /usr/bin. We can't use it when we break ties to /usr. We must log into root to do this setup.
sudo passwd root su -
See Linux Maintenance for SD card preparation.
cp -rp /usr/* /media/2ff2af82-3efd-4ce8-a768-a7055c5035a7 cp fstab fstab.org cp fstab fstab.new emacs fstab.new
Add to the end fstab.new
/dev/sdb1 /usr ext4 defaults 0 1
cp fstab.new fstab mv /usr /usrorg
Could do a umount /media/2f..., then mount /dev/sdb1 on /usr just for safety before reboot.
reboot
Got some errors during reboot. Check the mounts.
df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 6537352 2574324 3607908 42% / udev 499508 4 499504 1% /dev tmpfs 203328 876 202452 1% /run none 5120 0 5120 0% /run/lock none 508316 200 508116 1% /run/shm /dev/sdb1 15073280 1853092 13203804 13% /usr
All is good. Now I feel safe to remove the original /usr
rm -rf /usrorg df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 6537352 673724 5508508 11% / udev 499508 4 499504 1% /dev tmpfs 203328 876 202452 1% /run none 5120 0 5120 0% /run/lock none 508316 200 508116 1% /run/shm /dev/sdb1 15073280 1853092 13203804 13% /usr
My 8G SSD now has some breating room.
gnome
sudo apt-get install gnome

gnome display manager
sudo dpkg-reconfigure gdm
Also of interest before window start up
<ctl><alt> F1 sudo stop lightdm sudo start gdm
