Default display manager should not be gdm3
On my netbook I'm running a pretty vanilla install of squeeze,
although my personal desktop session is very different to usual.
I wanted to add a command-line option to my X server. I spent 15 mins
trawling through docs and grepping for config options with no luck.
So I asked a search engine.
It turns out that:
* There is no way to do this without patching the gdm source code
or using dpkg-divert to wrap the X server with a shell script
* Such a feature was requested in a bug in the RH/Fedora bugzilla
in June 2008 . It's also in our BTS . And in the upstream
BTS multiple times with patches (September 2009, October 2010) .
Despite a lot of demand, it still seems that this simple and
essential feature simply wasn't on anyone's radar.
* Worse, in September 2011 one of the upstream authors seems to
poo-poo the idea ! It looks like they are resistant to sanity.
gdm3 also has the crazy XAUTHORITY bug , which was reported
to upstream  who inserted a completely crazy "fix"  showing they
totally fail to understand how all this stuff is supposed to work.
That bug was fixed in Debian by the X maintainers adding a workaround
to the core X session startup scripts. Madness.
We should not still be using this software.
I don't have much of an opinion about the rest of gnome because I
don't use it. But we should be "considering our position" as they
