I've run linux on my laptop for several years now and it's always been a complete drag to setup. Of course, once it's up and running, it is up and running for good.
Unfortunately, it's a laptop and that means it goes to a lot of hostile places that I just don't trust. I would like the ability to reinstall the machine without too much trouble. I also use my laptop as a testbed for new libraries and such. Also, I run a dual boot of windows on it so I can play starcraft with my boys. Needless to say, it'd be nice to be able to reinstall it about once a month without too much grief.
Gentoo on the desktop and server is WONDERFUL but gentoo on the laptop is just sad. :( With that, I've tried a couple of different distros lately. Fedora Core was ok, but I just can NOT handle it. Too thick too bloat too much. I even thought of just going knoppix and living on a fat32 on my hdd, but that's not there either. Right now, I am running ubuntu on it and the install was great. It just setup everything perfectly, including the display at 1400, wireless, sound, etc. As a matter of fact, it detected my Linksys WPC11 wireless card and used that for the install. It really seems tied to gnome (i like fluxbox) but if I can live with that, I'll be ok. If I could get it to use fluxbox, and then rsync my whole homedir to my lanserver to save all my prefs, etc, that would be wonderful.
