Both svgalib 1.3.1 and pre1.4.0 do not restore all the required VGA registers when exiting a graphic mode. Only a reset helps :-) The hardware which gives this problem is the following: An IBM MB with an onboard Matrox video which is disabled and a ATI Charger 3D 4M which is the active card. The same ATI card on a different computer works fine. So I suspect that SVGAlib is somehow tricked in believing that it has an Matrox card. All programs that need SVGAlib behave in the same way i.e. they function well until a return to a text mode is required. Details of the video cards: Video Chipset: Matrox MGA-1164SG Video Card: Matrox MGA Mystique 220 Video Memory Size: 4,096 KBytes of SGRAM Video Card Bus: PCI Video BIOS Manufacturer: ATI Technologies VESA Manufacturer: ATI MACH64 VBE2 Vendor: ATI Technologies Inc. VBE2 Product: MACH64GT -- Regards, Liste -- A common mistake that people make when trying to design something completely foolproof was to underestimate the ingenuity of complete fools.
