John,
Thanks for the response. However I still cannot get it to show a "/dev/fb"
device. The command "cat /proc/fb" is size 0.
When I add "vga=xxx" to the grub (v1.97.2) boot command, I get the following
response from grub, input first:
- Input:
- insmod ext2
- set root=(hd0,3)
- linux /boot/vmlinux-2.6.32.8-lfs-6.6 root=/dev/sda3 ro vga=789
- boot
- Output when the "linux" line is entered
- vga=789 is deprecated. Use set gfxpayload=800x600x24,800x600 before
linux command instead.
And after the boot the "/dev/fb" device is not present. So I tried the
following grub command:
- Input:
- insmod ext2
- set root=(hd0,3)
- set gfxpayload=800x600x24,800x600
- linux /boot/vmlinux-2.6.32.8-lfs-6.6 root=/dev/sda3 ro
- boot
Still no luck. Here are my kernel .config settings related to FB
CONFIG_FB=y
CONFIG_FB_BOOT_VESA_SUPPORT=y
CONFIG_FB_CFB_FILLRECT=y
CONFIG_FB_CFB_COPYAREA=y
CONFIG_FB_CFB_IMAGEBLIT=y
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_TILEBLITTING=y
CONFIG_FB_VGA16=m
CONFIG_FB_UVESA=y
CONFIG_FB_VESA=y
CONFIG_FB_EFI=y
CONFIG_VT_HW_CONSOLE_BINDING=y
Anyone have other words of advice? Thank you in advance,
Ian
