Low Graphics mode is a message you get in certain Desktop Environments when X is unable to properly load hardware accelerated GPU drivers. It means that all icons, windows, drop shadows, and animations associated with your window manager are rendered by the CPU, not the GPU.
This typically occurs when a proprietary driver installed manually conflicts with files used by the open source driver. the X200 uses and Intel GPU so I'm not sure why you would be getting that message. There is only 1 driver and it typically doesn't decide to stop working. I would guess 1 of the following 3 things is happening 1) hardware failure 2) corrupt files in your installation 3) Ubuntu sucks There are a lot of little files that can get screwed up during an upgrade so I'm leaning towards #2. It's actually a very common problem in Ubuntu.
