By default, "Log File Viewer" is not launched from Unity as root in Ubuntu 11.04. This is pretty useless, as most of the log files are only readable by root.
How can I change this behavior so that it launches as root?
Backup and modify /usr/share/applications/gnome-system-log.desktop; change line:
Downside is that it will now always ask for a password.
You could also install a similar utility called glogg - It would make it easier to run as sudo
