This morning, hardworking Debian developers pushed the remaining pieces of the brand new X.Org 7.3 to Debian sid (unstable) distribution. And it must be said, a well done job!

ii x11-common 1:7.3+2 X Window System (X.Org)
ii x11-session-utils 7.3+1 X session utilities
ii x11-utils 7.3+1 X11 utilities
ii x11-xfs-utils 7.3+1 X font server utilities
ii x11-xkb-utils 7.3+1 X11 XKB utilities
ii x11-xserver-utils 7.3+1 X server utilities
ii xbase-clients 1:7.3+2 miscellaneous X clients - metapackage
ii xorg 1:7.3+2 X.Org X Window System
ii xorg-dev 1:7.3+2 the X.Org X Window System development
ii xserver-xorg 1:7.3+2 the X.Org X server
ii xutils 1:7.3+2 X Window System utility programs
I'm pretty convinced that X.Org 7.3 will work well for people, unless you're using proprietary display drivers, that is. I feel forced to use Nvidia drivers, because open source ones are quite slow (nv) or not yet ready for general usage (nouveau). Even though 100.14.11 is the latest published version of Nvidia drivers, it is not ABI compatible with X.Org 7.3. So, until Nvidia officially supports X.Org 7.3 (which should happen soon), here's what you can do to get them running together in the meantime. Edit your
/etc/gdm/gdm.conf and add this small chunk of configuration just below [servers] section at the bottom of the file:
command=/usr/bin/X -audit 0 -ignoreABI
Even with this workaround, if you peek into server log file (
/var/log/Xorg.0.log) you'll find some verbose errors/warnings, but from what I can tell (after few hours of working on this setup) everything's working just fine.

Let me just add that I don't use any 3D compositing manager (compiz-fusion or similar) at this time, so your mileage may vary if you have more modern setup. I just got tired with lots of bugs in compiz-fusion 0.5.2, so I decided to wait a little bit for things to stabilize, before I give it another chance.
