I've been installing Ubuntu 5.04 on one of my PCs (a P II 400MHz with 384Mb RAM which previously has SuSE 8.1 installed).
The install ran pretty smoothly, the hardware is pretty vanilla. Sound isn't working, it doesn't report any errors and seems to try to play the sound but nothing comes out of the speakers. That said, I've never managed to install any distro on any PC and have the sound work without a lot of fiddling and downloading of additional drivers.
I am finding that I'm having problems in that I'm having to fight the operating system to get it to do what I want rather than what it thinks I want.
I can access shared drives on my Windows XP boxes through the file browser app by entering the URI in the address box (i.e. smb://machine/drive) but it won't mount them (it doesn't have smbmount and the package manager doesn't list it as being in any of the available packages, I have all the Samba packages installed). Also whilst the installer found the second hard drive (and it would partition and format the drive) it won't let me create or mount any file systems on it. The box has a 6.2Gb drive (IDE master) and a 10.2Gb drive (IDE slave). It installed on the 10.2Gb drive to give me about 9.6Gb of file system space plus about 500Mb of swap.
The struggles will continue.
