I got my modem working in Slackware in 1997 - but the PPP driver (equivalent of WinSock - which worked in Windows quite well at the time) would only work during the first boot of the system. After a reboot, PPP would never return, and the best I got out of the internet about it at the time (mostly using my Windows PC) was "real men connect to the internet through ethernet."

Between that an the useless (unless you enjoy frustration) sound drivers, I declared Linux "not ready for prime time," and left it to others until starting back in via Cygwin in 2003, then Gentoo (for 64 bit access you couldn't get any other way) in 2005.

Similar story but I just installed slackware on one of the University PCs (they just had a handful of PCs in the general computer room for the students and nobody actually watched over us) since I did not have a PC yet (only had a ZX Spectrum at the timback then).

Trying to get X-Windows to work in Slackware was interesting, to say the least: back then you had to manually create your own video timings configuration file to get the graphics to work - which means defining the video mode at the very low level, such as configuring the number of video clock cycles between end-of-line-drawing and horizontal-retrace - and fortunatelly I didn't actually blow up any monitor (which was possible if you did the configuration wrong).

At least we had some access to the Internet (most things were blocked but we had Usenet and e-email and one could use FTPmail gateways to download stuff from remote servers) via Ethernet, so that part was easy.

Anyways, my first reaction looking at the OP's post was like: yeah, if they're running X it's probably a too powerfull machine.
