Installing Ubuntu 7.04 (Feisty Fawn) on a ThinkPad T60
Ubuntu Feisty Fawn is still under development (alpha status) and works fine on a T60 UT-049GE.
The installation worked without any problems. The new network manager is great as it now supports a useful roaming mode. The system runs stable since 3 days of work. No crash, no severe bugs. I would recommend it for experimental systems lovers. :)
Some might expect problems. I don't know, if this is fixed: In particular, on a 2007-72U the installer crashed - see bug report. The next beta releases are planned for February 1st and 15th, respectively (see Feisty Release Schedule). The final release is planned for April 19th 2007.
