Uvesafb
How to : Framebuffer: Userspace VESA VGA graphics support
Uvesafb is an improved framebuffer driver for Linux systems with some enhancements compared to vesa. Uvesafb can allow you to get a full-resolution console, even if you have installed a graphics driver that does not support full-resolution consoles. Examples of drivers like these: ati-drivers and NVidia-drivers.
Kernel configuration
Device Drivers -> <*> Connector - unified userspace <-> kernelspace linker ---> Graphics support -> [*] Support for frame buffer devices ---> [*] Enable firmware EDID Console display driver support -> [*] Video mode selection support [*] Video mode handling helpers Frame buffer hardware drivers [*] Userspace VESA VGA graphics support
Build the kernel, do not install the kernel and modules. You can choose uvesafb as a module, unlike vesa.
Klibc
Next, we emerge No results:
root # 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
No results is the userspace helper that runs x86 code in emulated environment. Uvesafb will not work without v86d. Now, we emerge v86d
:
root # emerge v86d
Back to kernel configuration
Reconfigure the kernel:
General Setup-> [*] Initial RAM filesystem and RAM disk (initramfs/initrd) support (/usr/share/v86d/initramfs) Initramfs source file(s)
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
boot { generate grub default "Funtoo Linux uvesafb" timeout 3 } "Funtoo Linux uvesafb" { kernel bzImage-uvesafb[-v] params += video=uvesafb:1440x900-32,mtrr:3,ywrap }
Then run:
root # boot-update
and then run:
root # reboot
and enjoy uvesafb!
