I've hit most of the issues in this thread.
I hit the Evolution segfault mentioned here
. Strangely, when running with strace it didn't segfault and subsequently ran perfectly normally. The conversion to maildir might well be worth mentioning in the release notes for the update (if you mention software not a part of the default install). From a user perspective you end up with another email account login@localhost which can be removed and .local/share/evolution/mail/local_mbox with the original pre-migration version of mail taking up disk space.
I did an install of 201109-gnome-dvd-64bit on two boxes. After removing mono-runtime, libgdiplus and pidgin, I did a full update and added the new sources at the head of this thread. On one box the update ran smoothly through mintupdate, on the other box it crashed repeatedly and I just dist-upgraded from a shell. I installed the gnome package with gnote. I'm mostly using Gnome Shell. These are the issues I haven't seen mentioned.
I've hit this
pulseaudio bug, which requires removing everything after line 20 in /usr/share/alsa/pulse-alsa.conf.
Network manager is requiring administrator access to alter network interfaces and only allowing access to global settings rather than per user settings. Both dbus-daemon and polkitd appear functional. Adding the user to the netdev group doesn't seem to help. Admin access shouldn't be required for a locally logged in user to mod interfaces (unless you run Suse
Font rendering seems particularly bad and gnome-tweak-tool doesn't allow control/querying of sub-pixel rendering status. I don't know where that is stored in gnome3. Is it possible that libfreetype6 is the debian build with all the patent troubling hinting code switched off? Changing levels of hinting does seem to make a difference but fonts still look blocky in comparison to update pack 3.
Using an nvidia card, I had to install the binary drivers as the nouveau drivers simply didn't work with gnome shell. I hit the same problem with Sabayon 7, so I guess it's a stage the nouveau drivers are going through.
The nvidia drivers are giving me a UBB warning, which is meaningless to me.
[ 14071.282] (WW) NVIDIA(0): UBB is incompatible with the Composite extension. Disabling
Currently it's not allowing xrandr styley changes of display resolution but that might be to do with my xorg.conf monitor section not giving enough detail.
I think that's about all the problems I've hit, which makes it pretty smooth all in all. Cinnamon is shaping up nicely and it's nice to get to see it on LMDE. It's a pity that both Cinnamon and Gnome shell are less accessible than Gnome 2. If anyone has knowledge of a clutter magnifier that works like compiz ezoom, I'd love to know.
