Using tmpfs for Security and Speed

I have 3.9GBs of RAM of which Ubuntu 10.04 (Lucid Lynx) hardly touches more than 512MBs so I'm going to move all my temporary files to RAM. This will result in 2 things:
  • Reading and writing temporary files will be much faster.
  • Temporary files will be more securely removed on shutdown.

nvidia-current Driver Failing to Load

I've had a really odd issue bothering me the entire time that I've been running Ubuntu 10.04 (Lucid Lynx). About half the time when I start up my computer I get a message that Ubuntu has failed to load the proprietary nvidia driver and is running in low graphics mode.
