Ran linux in an 8 mb 486 in the 90s. X ran in 256 color mode and twm or mwm were the window managers. It was so hard to use though. Had to setup modelines settings for your monitor in a textfile and theoretically could damage it with wrong iputs. Programming X fuggedabout it - I was from turbo borland msdos land where everything was neatly documented and designed with clear examples to make programming easy. I was lucky to get an x program to even compile. Hard to find books back then. Pre Amazon. Xv image viewer probably the only thing i used X for. Actually used the machine most of the time in the text mode terminals using alt function keys and used lynx as a browser (before javascript… but gopher was becoming obsolete at that point… ftp still popular though ) with random assortment of svgalib programs for any graphical stuff. Still there was something magical about seeing that black and white check pattern come up and the little X mouse cursor appear.. like there were… possibilities.
Yes, I remember making my 12" IBM monitor scream as I put the wrong mode information in the config file for X. I think I was on RedHat 5.0 from a cover CD, on a 486 DX2 with 64 MB of RAM (I was poor; everyone else was on Pentium IIs or IIIs and I was using computers the school threw out, scraping together motherboards and RAM).
Yeah, it was a different world. I worked at a company using X + Motif on SCO Unix back in the early 90s. I had a 386sx with 8mb ram + 6 MB on an ISA expansion card! When you changed a header file constant (like a label string) and had to recompile the ~1 MB(!) executable, it really was coffee break time - compile time was ~1 hour for a full rebuild. Strangely enough, our current project on a 16-core VM also takes nearly an hour for a full rebuild - but we have parallel build options that go much faster.
I also ran Linux+X11 on my 486 (for some grad work) with 32 MB, IIRC. ATI Mach32 graphics card, Nec 5FGe monitor (loved that one!), etc..
