I have made a reinstall form clean install on my 80GB hd with kernel 3.16.5-gentoo.
When I setup the grub.conf have I normally used the setting from my other gentoo pc there run amd64 x86_64 and a kernel there is older than 3..x.x kernel
And I have both a kernel 3.14.14-gentoo and 3.16.5-gentoo on it.
Here is the grub.conf setup with :
root (hd0,1)
kernel /kernel-genkernel-x86_64-2.6.39-gentoo rootfstype=ext3 real_root=/dev/sda3 ramdisk=8192 init=/linuxrc root=/dev/ram0 vga=0x317 video=vesafb:mtrr:3:ywrap spalsh=silens
This can boot with the newer amd kernel but the kernel of newer is use to much mem for some programs.

But it is not the first problem, it is the new clean install i have done
on the new clean gentoo install have I tried to use the same line for the kernel in grub.conf and it make the install to halt and give errors.
so I have this line in grub.conf
root (hd0,0)
kernel /boot/kernel-genkernel-x86_64-3.16.5-gentoo rootfstype=ext4 real_root=/sda3
all of the other commands and functions in the line makes gentoo to halt by errors.

It Work but when gentoo is running is it with normal monitor and vga fonts
I like gentoo here to use smaller font for the monitor so I on this monitor can see ting by 0x317 or 791 pixels or some smaller but not so small that I have problem to see Things on the monitor.

So how can i make this be done?

What video card are you using?

I think you have to compile a kernel with framebuffer support and then pick a mode that is supported by your video hardware. If I've read you right, you wanted to get 1024 x 768 @16 bpp.

I ended up compiling uvesafb into the kernel (no initrd necessary).

hwinfo --framebuffer gave me the framebuffer modes my card supports. I chose one and specified it in my rEFIind.linux.conf file (I don't use a bootloader)

Hope this helps.

Sorry if I've misread you somewhat. English is obviously not your first language. You're doing much better than I would in Danish, though.

You might get more help if you moved this to the Kernel and Hardware forum above, BTW.
