Well, I had to install xbase-clients by hand, otherwise there's no X11-forwarding via SSH. This is not in any way related with ROOT, but it made me ask myself whether some dependency might have been missed because some packages are always there by default on a normal desktop install. Up to now it looks fine :-)

Without the Qt plugin it gave no errors, but with it I got

rkuhn_at_rk:~$ root

Make sure your local "~/.fonts.conf" or "/etc/fonts/fonts.conf" file points to "$ROOOTSYS/fonts" directory to get the proper support for ROOT TLatex class

To check e.g. library loading I tried 'gSystem.Load("")' and got again two Errors with qt and none without. The library seems to work, though.

Keep in mind that they've been built on testing, not unstable. Should work, but I thought I'd mention it.

I'm doing some stress tests now. Don't look too much at the performance, I've only got a xen virtual machine on a single CPU host system and memory is quite limited.

I've not noticed any failures (stressGraphics seems to require the creation of a file which I cannot write as non-root, stressHepix seems to want to call only the other stress tests, which fails because I don't have '.' in my PATH, and I shouldn't be forced to).
