fedora Core 5 test 3
A few problems I've had:
1) doesn't recognize QNX software
2) desktop settings not carried over from Gnome to KDE
3) K3B burner failed
4) Grub only recognizes 2 of 3 partitions
5) monitor not autodetected for refresh and display rates
A few good points
1) quick boot
2) impressed with packages and user tools
I'll probably uninstall FC5 T3, install debian, then reinstall FC5 stable release.
Personally, I like the linux distros.
