I was forced to try Ubuntu Hardy in the new university pool. The setup includes one Linux server dedicated for the pool, one Windows AD for Kerberos authentication, one Windows fileserver with user data and 20 clients. The clients are new HP machines with a Radeon Xpress 200 card.

First problem was nasty, the X server turned the display black and then crashed, leaving an unusable console behind. Even a blacklist of the radeon module does not work. Somehow the Xorg radeon driver loads the module on its own, ignoring the modprobe blacklist. Only a hard blacklist using install radoen /bin/false in the modprobe config was able to prevent this. Lets hope that the endeavors to remove much priviledges from the X server goes good.

For the homes two setups was tested:

• Homes on the Windows server via cifs, mounted via pam_mount using NTLM password.
• Homes on the Linux server via nfs version 3.

The first one just produced an error that some Gnome component was unable to lock ~/.ICEauthority. This could be worked around in the Xsession. Otherwise it was usable to slow, which may be a problem with the Windows server.

The later, plus a reinstallation with fglrx, produced first unresponsive OpenOffice.org windows and then a complete unusable Gnome desktop. I would not completely vote against a problem with fglrx or even a broken installation, but the amount of problems exceeded the threshold.

Now we will try Lenny and see if this also happens there. Especially home via nfs is not that uncommon that we can let it broken in a release.
