Tim, set the root password on Ubuntu was necessary only for replacement for sudo using sudo-trinity? With 3.5.13.1 this is not necessary. Sudo-trinity is updated, so it serve as a complement to sudo from the system. It appears that it is possible to remove the information about the known problem with libart - is also updated. I also propose to remove the instruction to add my PPA. http://www.trinitydesktop.org/wiki/bin/view/Documentation/UbuntuBinaryInstallation Slavek --
