I have an IBM thinkpad 760el with a Trident Cyber9385 (as reported by SuperProbe; I think it has other names like TGUI9660). It has 1024Kb video ram. That's enough for 800x600x16.
I am trying to get framebuffer running so that I can get 800x600 text mode and use the full 12.1 in display. It does not work when I compile it into the kernel. On boot up it merely says VGA 80x25. I suspected my bios is not vesa 2.0 compliant, but when I set kernel to vga=ask, it says VESA somewhere in there (not sure exactly where). When I probe for more modes, it finds none. Entering standard vesa modes returns "invalid mode." I talked to IBM and the technician told me that vesa 2.0 is a very old standard. My laptop was made in 1993. If I compile the VGA framebuffer (16 color), I get a boot logo :) (which, at the end of the boot process, changes to messed up colors??). But I cannot get to 800x600 using fbset. It says "ioctl FBIOPUT_VSCREENINFO: Invalid argument" When I change fb.modes to use 4 bit color instead of 8, then it "works." I guess that makes sense because VGA 16 wouldn't support 8 bit color.... So in 4 bit, things happen, but I get a corrupt screen, I see the very left edge three and a half times. I am using my converted X-modeline. X runs fine in 800x600x(8|16). Is it possible to use vesa framebuffer on this laptop/video card? Am I doing anything wrong? -- Pat Mahoney <[EMAIL PROTECTED]> For children with short attention spans: boomerangs that don't come back.
