I just got internet service back after an interruption of almost two months. (A major earthquake and two major typhoons including the biggest one in history. Yes, I'm in the Philippines.)
Ubuntu Updater immediately told me that there were 228 updates pending. I told it to go right ahead. After a couple hours it said it was done and requested a reboot. After the boot the display was significently screwed up.

The trash left behind can be cleared by going to the Workspace Switcher briefly and returning. When you do this the first time the wallpaper disappears, along with the trash, and from then on the desktop is black. The smear from the launcher when on autohide does not clean up.
Everything inside an active window is normal.
I tried cold boot and a different login.
I rebooted and backed up to older kernal versions.
I tried apt-get autoclean, purge, etc. in case there were remnants of some update left around causing trouble.
I have a fairly vanilla Ubuntu 13.04 with Unity.
Hardware is a Gigabyte 880GM-DH2 mb with Athlon II X2 240 and 4 GB of DDR3/1333. It's all been working fine for six months.
Display is on board. I don't remember what it is and a quick Google didn't tell me. ATI something I'm pretty sure. "Software and Updates" tells me I'm NOT using any propriatary drivers.
I could use some help. After being internet starved for two months I've got a lot of catching up to do. Please don't tell me I need a clean install. Last time it was weeks before I got everything right again.
