2.6 kernel and framebuffer

2.6 kernel and framebuffer
I've installed both 2.4 and 2.6 kernels. With 2.4 I don't have any problems with the framebuffer coming up at 1024x768. With 2.6 though it always seems to default to 800x600 no matter what I set it to in grub. I know it's more of a cosmetic thing, but has anyone else run into this issue and know how to resolve it?
I'm using whatever the standard framebuffer driver that comes from using an initial compile using genkernel. I'm in the process of reinstalling the whole os right now, but the grub.conf should look something like:
default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.10-gentoo-r6
root (hd0,0)
kernel /kernel-2.6.10-gentoo-r6 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3 video=1024x768-16@60 splash=verbose
initrd /initrd-2.6.10-gentoo-r6
At one point I even changed the video statement back to the vga=788 statement that kernel 2.4 uses and it made no difference, still showed up at 800x600.

Actually I didn't know that command existed. I just emerged and tried it. Assuming the proper syntax is
fbset -xres 1024 -yres 768
It reset it to 1024x768, but it then abended the system completely locking it up. Had to hard reboot it.

It depends on the vesa driver which you use.
If you use the old Vesa you should go with the old "vga=7xx"; otherwise if you set up the new vesa-tng you can set your modes in the kernel configuration to: (for example) 1024x768@60 and set the grub command line to "video=vesafb"

Yeah, line in grub should read video=vesafb vga=0x318 for the vesa framebuffer at 1024x768, 16 million colors (0x317 for 64k). With vesa-tng, you set the resolution in the kernel config, or you can do it in the command line as well, depending on what suits you.

Also, incase you know what your vid card is (dmesg) here are a few option on the kernel level:
Then you can use radeofb etc (this an example of my grub.conf kernel line):

You use the in kernel radeon support? I use the ATI drivers ebuild and load the drivers as a module. Then again I have a newer card, that only works with the latest drivers. However I don't think it's really ever a good idea to use in kernel support when it comes to graphics cards.

It's an older laptop, so the chances of changing graphics cards in it is a bit slim, plus it doesn't cause gensplash graphics to go corrupt when switching from silent to verbose during boot when I compile it into the kernelSith_Happens wrote:You use the in kernel radeon support?
