I ran alpha 2 all day on another hard drive. This is what I found out!
Pros: Base system has a stable feel.
Xorg 7.3 seems to work well.
Gimp updated to 2.4.2 (More features, red eye remover, etc.)
The 18.104.22.168 kernel seems solid.
Network Manager works properly.
Gnome 2.21.4 seems to have fixed the GDM error problems and has introduced a better looking Resources tab in System Monitor.
Cons: OpenOffice Base will not install because of an unmet dependency. (Should see a fix soon.)
Can not add wallpaper! (Eye Of Gnome can be used to set the wallpaper for a work around.)
Logon and logoff sounds are not working by default. (Workaround here http://www.pulseaudio.org/wiki/PerfectSetup
) Multimedia sound worked with all apps.
Background color at logon is tan and has to be manually edited to change.
Some screensavers will not run and the Floating Ubuntu screensaver is missing.
For an alpha release the problems found are very minor. All of the bugs mentioned here have bug reports filed. I am looking forward to the next release to see what progress has been made.Quite nice for an alpha release!
Thought some might be interested since LinuxMint is based on Ubuntu.
