Hi Gentoo masters,
I have a Gentoo on my Dell XPS 9350. I followed the instructions at
https://wiki.gentoo.org/wiki/Uvesafb
with all kernel options set and v86d installed.
I first tried to compile uvesafb into the kernel with the kernel options
video=uvesafb:1920x1080-32,mtrr:3,ywrap,
then I get the following error
| Code: | # dmesg | grep -i vesa
uvesafb: Getting VBE info block failed (eax=0x4f00, err=1)
uvesafb: vbe_init() failed with -22
uvesafb: probe of uvesafb.0 failed with error -22
|
Then I tried to compile uvesafb as a module, and load it by adding it
to /etc/modules-load.d/uvesafb.conf and related options at /etc/modprobe.d/uvesafb.conf
Then I get exactly the same error, However, before this error I got
| Code: | # dmesg | grep v86d
v86d: EBDA too big (17c00), truncating.
v86d: Video BIOS not found at c0000.
v86d: v86 memory initialization failed.
|
Do you have any ideas on how to fix this? |

Why do you want uvesafb anyway? Intel is with KMS (kernel modesetting) and you get full resolution console from there. I don't see what uvesafb would give you, if it could even work in any way (well, I guess it can, as long as you don't want to run any graphics like xorg-server whatsoever)

Right Leio,
I just focused on what sunk wanted to do. But with Vesafb and Uvesafb you can use the Vesa and the Fbdev Xorg modules. They do not use material acceleration. For this the kernel must use the Intel framebuffer support i915 and the Xorg Intel module.
