Yeah but you could trim it ((-:. (II) I810(0): VESA VBE Total Mem: 1024 kB (II) I810(0): VESA VBE OEM: Intel810(TM) Graphics Chip Accelerated VGA BIOS If I am right, this says you have 1MB video ram. This is not enuf to do much. Then it gets upped (II) I810(0): I810CheckAvailableMemory: 151548k available (==) I810(0): Will alloc AGP framebuffer: 8192 kByte So now you have 8MB video ram. Still not much. Now looking at the highest 640x480 resolution available: (**) I810(0): *Default mode "640x480": 36.0 MHz, 43.3 kHz, 85.0 Hz (II) I810(0): Modeline "640x480" 36.00 640 696 752 832 480 481 484 509 -hsync -vsync the frequencies available are just too low. If I am correct, you will have to up the video ram to at least 16MB. Try to use (==) Depth 24 pixmap format is 32 bpp is asking for too much. I have never used the Intel 810 chip, so someone more knowledgeable than me will have to take over.
