Mepis was my first distro that I actually got to learn before I went off on a tangent and did distro hopping. Recently, I installed it again along with my Windows & Ubuntu partitions & I think that's where I'm staying.
If you're still curious, PCLinuxOS is another good distro to look at. I prefer deb over rpm because it installs faster, but it's still worth checking out.
While the partitioner didn't hang in Ubuntu 6.10, I noticed that it paused for a little at 50% before it went to the next step. Mepis is based on mostly dapper(6.06) & a few breezy(5.10) packages, which is more stable than edgy (6.10).
I find it strange that Fedora gave you errors about your cpu because it uses the newest kernel. I didn't have any issues with it until its flood of updates came in, along with whole new kernels, which broke my wifi & nvidia drivers.
With openSusE, I had to give a "maxcpus=0" at start & a noapic when it was installed. It worked fine, but it was too slow for me.
--On a side note, if you have a modern nvidia card (geforce 3 & newer), synaptic will try to install version 8776 of nvidia-glx. Don't do this because the kernel is built around 8762. Instead, get this file:
http://security.ubuntu.com/ubuntu/po....11-1_i386.deb
and install that. Next, under synaptic, search for nvidia-glx, select it, click package, lock version, and choose 8762. That way, synaptic won't update it.
Anyway, enjoy using mepis!
