How to : Framebuffer: Userspace VESA VGA graphics support

Uvesafb is an improved framebuffer driver for Linux systems with some enhancements compared to vesa.

Kernel configuration


Build the kernel, do not install the kernel and modules. Note, that you can choose uvesafb as module, unlike vesa.

Klibc

Next, we emerge dev-libs/klibc (package not on wiki - please add):

# emerge klibc

This step is necessary because klibc has to be compiled against a kernel that includes uvesafb. You need to do it only once.

v86d

sys-apps/v86d (package not on wiki - please add) is the userspace helper that runs x86 code in emulated environment. Uvesafb will not work without v86d. Now, we emerge v86d:

# emerge v86d

Back to kernel configuration

Reconfigure the kernel:


Rebuild the kernel: make and install it, install the modules

Bootloader configuration

add video=uvesafb:1440x900-32,mtrr:3,ywrap (or similar) to your kernel command line, like in example boot.conf

{{{name}}}
{{{body}}}

Then run:

# boot-update

and then run:

# reboot

and enjoy uvesafb!
