Giving you, if you were lucky, VESA graphics and maybe a mouse pointer because XFree86 somehow insisted on being told whether you have a PS/2 or USB mouse. 3d acceleration only with nvidia and that required manual installation because nvidia never provided anything but blobs. IIRC ATI drivers were simply non-existent (didn't have an ATI card back then), that only changed when AMD bought them. Whippensnappers won't believe it but once upon the time, nvidia was actually the company to go with when running linux. And Epic didn't hate Linux yet, UT2004 came with linux binaries on the dvd.
