I figured out what seems to cause the problem and I can reproduce it. It has to do with the new network-manager and/or restricted-manager The delay is caused because my wireless needs to connect first to the access point, but before it does that it first needs to work out that there is an access point, wpa, etc.
I'm using a Dell M90 x64 dual core laptop with an NVidia card and ipw3945ABG wireless drivers To reproduce the delay (and it is really a delay 1-4 min depending from boot to boot) boot a laptop without being connected to a wired network login .. start waiting -- desktop loads incredibly slow after todays upgrade and wireless doesn' t come up automatically https://launchpad.net/bugs/92997 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
