Sometimes, usually when updates are installed, after booting, I get a gdm screen similar to this - http://lippolweblog.files.wordpress.com/2009/09/gdm.png. It uses the same animations as the new black gdm, but it just has the plain white layout as of the old gdm 2.x. Has anyone experienced this? What is the cause?
The "older" UI is shown when detection that your graphics card has the necessary OpenGL support fails. That includes a timeout. If your machine is starting a lot of services at boot, and if your hard drives are too busy loading stuff to run the test tool as quickly as they should, this may happen. It likely won't be shown if you get a faster hard disk. Clearly a bug though.
I'm not sure the speed of the HDD makes much difference. I've got a SSD and on occasion I get it as well. I also occasionally get a fall back to the old style dialog when logged into the desktop. One minute I'll get the new one when I need to unlock a ssh key, the next the old one when I need to put in some network details and then back to the new one (not saying it's network, that's an example, can be any dialog) when it's running g-s fine. Tends to happen more when the machine has been up for longer.
