Question Centos 5.3 not able to use a framebuffer?


I don't really understand what is going on. I added vga=### or vga=0x???? to the kernel line but when I boot up I get prompted to select a video mode. In that I can select even a 1440x900x32 setting yet I cant get the thing to be set in the menu.lst for grub.

I've check the wiki and tried what they said with no luck.
http://wiki.centos.org/HowTos/Laptop...01bca5f7930e32

I wanted to know if anyone got this working with centos or not?

A list of vga codes (this is also what I get prompted with when the code is wrong and I can select the 1440x900x32 with no problems). I don't know why it cant pass the code through.
/questions/blog/lifeforce4-30748/a-more-complete-vga-resolutions-list-for-grub-and-lilo-2000/

I have tried on the kernel line the following:
vga=791
vga=0x0365
vga=791 video=intelfb

Thank you,
Kyle

Weird. "menu.lst" is just a symbolic link to grub.conf. Adding "vga=792 video=intelfb" to the /boot/grub/grub.conf kernel line works OK.

I have not had time to try it again I will do so today but I was having other issues with video because of the Xen kernel. That might have been causing the framebuffer issue as well.

I'll update this reply with an answer if it works or not.

Thanks,
Kyle

Yeah so it was the xen kernel that was the issue. I was having nvidia driver issues with it and once I went to the regular kernel with out xen the fb worked just fine.
