How do I make XFree86 version 3.x- or XiG Xaccel 5.0.3- work with Solaris 8?
You can’t. X servers for previous versions of Solaris rely on /dev/vt* virtual terminals, which have been of end-of-life-ed in Solaris 8 (see an earlier question). You’ll get an error message similar to: xf86OpenConsole: Cannot determine current VT. You must upgrade to XFree86 version 4.x or better which is currently (7/2000) available only in source. XiG released 5.0.4 as a binary patch for its commercial X server. See http://www.xfree86.org/ and http://www.xig.
