Ubuntu 8.04 has been installed, and I’m pretty much committed to it. Everything seems to be working fully with no issues at all.
My refuge where I was considering abandoning Ubuntu was Arch Linux, but a bug with X regarding stuck and repeating keys has not seen a fix there, and it kept biting me hard, especially during games — enough where I had to do something quite drastic, like, say, install Ubuntu.
So no worries now. Everything looks cheery and rosy again, and many of the issues and fears I had with Ubuntu 8.04 have melted away and I’m successfully using it again. Though I did have to install the Firefox-2 package, since the 3 beta kept thrashing the disk, getting terribly slow, and giving me all kinds of headaches. I would stick with SeaMonkey, but dealing with the plugin issue where one has to install as root every time there’s an update gets a little tiring. I am hoping this issue will be resolved in SeaMonkey soon (by all reports, it will), but meanwhile, I can deal with Firefox Version 2 Point SomethingOrTheOther quite nicely.
