We should mention the arch of the media as in the past problems sometimes affected just one type.
My KDE live CD was 64bit, and now for the Gnome 64bit live CD being tested here:
It made a lot of noise on my DVD writer, and seemed to take ages to load! The first splash was in English, immediately followed by the French “computer startet”, continuing in French until Gnome appeared, how odd. The “something of the night” theme continues from Gnome 3 on 12.2, on 12.3 its Gnome 3.6.2, but hoping KDE does something different for the final release.
Just my opinion, I think the dark theme works better on Gnome 3 where the desktop is more controlled, and desktop elements are fixed in place. The opposite on KDE where the desktop is freer flowing and the black theme seems to add nothing apart from eye strain. Of course, on KDE you can change almost everything.
Again no issues on real hardware, and once loaded the operation was stable, smooth, responsive and swift. Network instantly available, and Firefox worked flawlessly while posting these comments.
Gnome’s notifier/updater did not appear (maybe in anticipation of pending updates for packagekit). So I fired up YOU and 4 updates appeared, including the two packagekit updates that installed first. YOU restarted itself, to enable installation of the other two. That was different on KDE, where a logout/re-login was requested. I then fired up Software Management, but this Gnome version of YaST had “No changes to perform” (KDE version had an Installation Summary screen full of stuff to go). The Gnome version did show three extra groups (left-hand panel) of packages: Suggested (74), Recommende (43 ), Recent, uploaded last 7 days (3243). So you could select packages to install from those lists. Maybe that’s different once you install to disk, but I didn’t go that far.
Another well performing liveCD, if anything a bit snappier once loaded, than the KDE version.
