|
|
Hi all, I'm installing Gentoo with EFI (first time in EFI).
I configured all my system and GRUB2 and it starts at the boot but when I select the boot option it freeze the display on "Loading Linux 3.17.7-gentoo"
I read of similar issues about nvidia cards, efi and grub, but I don't solved trying several things (video=efifb, nomodeset, etc).
However I can log into my system via ssh.
It seems to appear that kernel doesn't load efifb driver so it can't create a vga console.
Anyone can help me?
My GPU is Nvidia 750
Here is the dmesg output: http://paste2.org/_v3cMBXgx
Here is my .config: http://paste2.org/_g7pzG23w |

uvesafb instead of efifb? That's what worked for me. _________________ MSI MAG B550 Tomahawk

I "solved" converting gpt label into mbr, so without efi. And it doesn't use framebuffer... If I boot via vga=ask and select anyone of available resolutions it became blank and boot.
I tried with vesafb, not uvesafb. |

My (older) Nvidia card didn't work with vesafb either, except for 640x480, and with some kernels, not even that. Uvesafb worked fully and enabled me to select a nice dense console resolution. _________________ MSI MAG B550 Tomahawk
