Linux

In (K)ubuntu, only sudo is allowed by default. To enable su, execute:

sudo -s -H

To enable graphical root login, edit /etc/kde3/kdm/kdmrc:

AllowRootLogin=true

1. Run as root cvs update -Pd in the gallery2 directory
2. Once your files have been updated, open up your Gallery 2 in your web browser and it will take you right to the upgrader automatically
3. More info if needed on the Gallery site

Sometimes the reboot, shutdown or halt command fail. Then this is the answer:

echo 1 >/proc/sys/kernel/sysrq echo b >/proc/sysrq-trigger
