I've searched the archives, Googled elsewhere, and read every FAQ, HOWTO, and man page I could find. This is a weird one. The situation: Dual-boot Dell laptop, running SuSE 8.2 and Win XP. Under XP, the monitor resolution is set to 1024x768, 60 Hz, 24 bit colour. The best SaX2 is able to do is 640x400, 16 bit colour. I can put up with 16 bit colour, but the resolution is not particularly good. The Hardware: $ sax2 -p Chip: 0 is -> Intel 855 GM 00:02:0 0x8086 0x3582 PCI i810 This has been attempted as an Intel 855 GM (i810 driver) and as a frame buffer device (vesa driver). The monitor is described in the manual as '14.1" XFT. I've configured is as both "Dell 1024x Laptop Display Panel" and "LCD 1024x768@60Hz". The XF86Config file has the following lines for modes...

It's the "no mode of this name" that's puzzling me. It may be a red herring, and the problem may be elsewhere (clock freqs?), but I'm really stuck. Probably from staring at the problem too long. I would be happy to sumarise all direct responses, and put them back to the list in a nice, easy-to-digest form. Help.
