Description of problem:
When using the console in vesa framebuffer mode, the boot logo apears all weird.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.add vga=0x303 to the kernel line of grub.conf
Actual Results: The boot logo appears all weird (striped).
I don't know if it's supposed to look that way, but it really looks awful to me.
Yep, happened to me too.
I was booting with vga=773 (1024x768x8bpp) and video=vesa:ywrap, and the logo
Some investigation has uncovered that RH changed the logo file
(include/linux/linux_logo.h), but failed to update LOGO_H and LOGO_W in
drivers/video/fbcon.c. The results are that the new logo (looks like it's
supposed to have a res of 2400x20) are not in sync with fbcon.c expected size
The other possibility is that the junk in the new linux_logo.h file has been
corrupted somehow, because I'm still trying to figure out why RH wants a bootup
logo with a width of 2400 - seems too big for me.
I think you can workaround this ugly logo by doing one of two things:
1. Grab linux_logo.h from RH 7.3, replace it, and rebuild the kernel.
2. Grab linux_logo.h and fbcon.c from kernel-2.4.19, replace em both, rebuild
the kernel, then see a TUX logo instead of RH's. :)
Basically, the bitmap for the logo in linux_logo.h must be EXACTLY synchronized
with the #defines of LOGO_H and LOGO_W in fbcon.c - and they are NOT sync'd in
