Updated last week to latest unstable version of Ubuntu, which is currently in it’s alpha 4 stage.  So far everything seems to be working well, minus a few tweaks which I’ll list here in case it might help out someone in the future.

Xorg compositing seemed much slower than Gutsy on first install, using the Intel x-server.  It was most noticeable when dragging large windows or scrolling pages in Firefox.  There are a few issues with the Intel x-server at the moment, but adding the environment variable “INTEL_BATCH=1” to your /etc/environment should give you a speed up.

After an update on Friday, my system was giving a “cannot resolve hostname” error anything I tried to do something using root permissions (sudo).  Since I wasn’t able to elevate my permissions and poke around in my network configs in /etc, I rebooted into my SysRescue live disk, and commented out the 127.0.1.1 alias to my hostname, then realiased it to 127.0.0.1 (in /etc/hosts).

I’ve read some debates on this method of aliasing the localhost on various mailing lists and I’m not sure the reasoning behind it.  As for now, it fixed my sudo issue and I’ll leave it as is.
