Ummm... the error message asked a pretty simple-seeming question: "Is svgalib_helper module loaded?" So as far as that goes, it does seem to be something you can check, and --if the answer turns out to be "no"-- to fix, by loading the module (it's a kernel module created during the install of svgalib, and if you haven't rebooted since you installed svgalib, it won't be loaded). If the module fails to load, what is the error after modprobe svgalib_helper? HTH, Holly -- gentoo-user@gentoo.org mailing list
