This morning I updated my Ubuntu distribution to 8.10: Intrepid Ibex. It took a fair amount of time on the hotel's wireless connection to download all the necessary packages, but after that the actual install was pretty quick. Upon restart, my tablet pen no longer worked. A quick peek at the xorg.conf file showed me why. Ubuntu 8.10 uses HAL (Hardware Abstraction Layer) to control a lot of the input devices (such as my trackpad) and it therefore commented out a lot of the device specifications in the config file. I removed the comment symbol (#) only from the sections dealing with my tablet pen (detailed in a previous blog) and restarted. Now everything seems to be happy and I once again have a working tablet pen. The hibernate function also seems to be working now, which is something I never did get figured out in 8.04. It takes a few seconds to go into and come out of hibernate (long enough to make you wonder), but it does indeed work.
The only weird thing I have discovered so far is again related to the function keys. After installing the acerhk module in 8.04, the mail client would open whenever I hit the web browser button and nothing would happen when I hit the mail button. Under 8.10, the web browser button still opens my mail client, but now mail button opens my web browser. At some point I should figure out what file controls how these keys are mapped and reconfigure it.
