When I first installed Ubuntu 12.04 Desktop on this machine the auto login worked fine. Now it does not. I've run some Google searches and I've seen plenty of the typical go to Settings and unlock and ... to enable auto login. But the setting is enabled and was working.

I suspect the issue has to do with having logged into KDE Plasma as the login screen is now the Plasma login instead of the original Unity one. Originally the machine was running Unity3D (the default) but I couldn't get my VNC viewer to work so it was recommended that I use Unity2D. However, before going to Unity2D I decided to try KDE Plasma. I believe this is when the auto login stopped working - I wasn't paying attention to exactly when the auto-login stopped working because I was attempting to solve another more pressing problem.

From what I remember of the KDE install instructions it isn't as simple as apt-get purge kde to get rid of the KDE desktop.

Any thoughts on how to get the auto-login to work again? I have crons running under that user that could be made root crons but I'd rather not.

I've had this issues across multiple machines and multiple versions of Ubuntu desktop (all 10.04 or later). Usually it happens with an old laptop I've put Ubuntu on but now it's happening on my primary dev machine (a quad-core PC recently upgraded to Ubuntu 12.04 desktop). The problem is this - I can connect to the machine and login with the password, the initial screen looks fine but never refreshes. I can see the monitor for the machine across the room and can see the mouse move and the menus pop up but the image of the screen on the PC in front me running the VNC viewer never updates. So the mouse and keyboard commands are working.

• Ubuntu 12.04 Desktop
• Ultra VNC Viewer (also seen with RealVNC's free VNC viewer)
• Desktop Sharing Static IP on eth0; Dynamic ID on eth1

I think it is an Ubuntu config issue because this PC used to work just fine with 9.04, 10.04, and 11.10 (over the past couple of years). I've also had a couple of laptops that used to have this issue with older Ubuntu's but don't with 12.04.

Additional info:

The Win7 PC I'm trying to use to control the Ubuntu PC is connected via 2 DLink 8-port gigabit routers. The Ubuntu laptop I usually control via VNC is typically only connected to the network via wireless. The screen refresh is choppy but usable. I've repeated the issue on a Win7 laptop which was connected via ethernet and wireless.
