How to : Framebuffer: Userspace VESA VGA graphics support
Uvesafb is an improved framebuffer driver for Linux systems with some enhancements compared to vesa.
Build the kernel, do not install the kernel and modules. Note, that you can choose uvesafb as module, unlike vesa.
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.
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
# emerge v86d
Back to kernel configuration
Reconfigure the kernel:
Rebuild the kernel: make and install it, install the modules
video=uvesafb:1440x900-32,mtrr:3,ywrap (or similar) to your kernel command line, like in example
and then run:
and enjoy uvesafb!
