I love “listening” to ‘gurus’ arguing back and forth about the best ways to solve my problems.
I learn so much it’s ridiculous.
I actually managed to go ahead and do a FULL KDE4 install with just 128 MB of RAM (though, I DO have a nasty habit of setting a 2-4GB swap space by default). It did run horridly, but I know that opensuse is rather heavy on the resources…especially in the VRAM dept. It’s just too ****ed pretty not to be. 
I’m pretty sure that the notebook is on it’s way down. It was originally owned by a corporate VP and they have a nasty tendency to not care properly for their machines…especially notebooks.
I’ve been rather busy lately so I haven’t had a chance to take a stab at seeing how much better running xfce as opposed to KDE/Gnome would be, so, unfortunately, no reports on that.
I would like to run openSUSE, but, so far, I’ve managed to get away with Slackware.
I’m not afraid of doing things via command line, but I am a recently converted windows user/guru, so, TBH, I kind of NEED a gui for stupid things like music playing and such. I’m sure, with time, I’ll be able to run about 90% of my apps and such through terminal or what-have-you, but (right now, at least) I would feel more comfortable with a gui (specifically, KDE…just because I like it more than Gnome [or I’d just run Debian on this beast]).
Slackware seems slowest when I try to use the internet for anything. Mayhaps my NIC is screwed. Wakarimasen desu. I’m not opposed to using Konquorer for my web/file browsing; I’m just used to firefox, though it DOES eat resources for breakfast.
The fact that I managed to install openSUSE 11.1 on half the “required” RAM gives me hope. Especially knowing now that there is an X that is lighter on the footprint. If it comes down to it, I’ll just keep Slackware 12.2 and call it a win that I could even get this thing running again (about $200 and twice as many hours later). I just REALLY like openSUSE. And, since I got it to run pretty well on my P3/900MHz/512 machine, I have faith that it will run on my notebook as well.
Essentially, my plan (at this juncture) is to try to see how xfce runs on 128. If there is marked improvement over performance and xfce isn’t too cumbersome for a noob like me to get the hang of, then I’ll go ahead and buy the two 256MB sticks and see how it works. Since openSUSE runs fine on my primary machine, it will still be my favorite/perfered OS, but, since the majority of major distribution command lines are the same [within a reasonable margin of error], I’ll just use Slackware since it is, probably, the lightest footprint of major distributions for the power of the OS.
*I WILL keep this thread alive with updates once I get to the middle mark (384MB RAM). It just might be a while.]
