Trying to install nvidia-driver (the proprietery one), and following this guide to the letter:
https://wiki.gentoo.org/wiki/NVIDIA/nvidia-drivers

However, when I reboot my machine, Grub (or what comes after grub) does not manage to use or find a framebuffer, so the last thing that is updated to the screen is EFI Stub:
The machine does continue to start, and I assume it is fully up and running (newly installed system, so I know I can ping it, and SSH to it, but I cant get to a terminal via SSH, as I get the following error message:
PTY allocation request failed on channel 1

I've tried to rebuild the kernel a few times, and I think I've singled out the issue, as soon as I turn of the Simple FB
Quote:
Device Drivers --->
Graphics support --->
< > Simple framebuffer driver


And enable
Quote:
Device Drivers --->
Firmware Drivers --->
[*] Mark VGA/VBE/EFI FB as generic system framebuffer
Graphics support --->
Frame buffer Devices --->
<*> Support for frame buffer devices --->
[*] VESA VGA graphics support
[*] EFI-based Framebuffer Support
<*> Simple framebuffer support


This is when I seem to loose the ability to boot, or use a frame buffer after boot to be more precise, I've attached my kernel config if anyone has any suggestions,

OK, the kernel configuration file is to long to post...

The machine is a:

ASUS TUF GAMING B650-PLUS WIFI
AMD RYZEN 5 7600
ASUS 4060 TI DUAL OC EVO 16G


Anyone else faced this issue?

vrghost,

you can use wgetpaste ( https://wiki.gentoo.org/wiki/Wgetpaste ) for your kernel .config. Maybe check before if you have enabled "Framebuffer Console support" and "Enable legacy fbdev support"

(see here: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_Configuring_Kernel_Version_6.6#Part_3_-_Must_Haves )

Amazing pietinger

Thank you so very much for that tip, should have checked that first

Also, I did notice that technically I think the EFI framebuffer does start, as its started at a higher resolution all of a sudden:

The strange resolution is because it uses half of a 49-inch screen

If you enable this:
Code:
General setup  --->
    [*] Configure standard kernel features (expert users)  --->

there is a little trap :lol:

You must re-enable block layer (already done) AND:
Code:
Device Drivers  --->
    Character devices  --->
        [*] Enable TTY
        [*]   Virtual terminal

Without TTY you have really a problem :lol:

(see also: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_Configuring_Kernel_Version_6.6#Part_1_-_Main_Menu )

And framebuffer console depends on VT (and FB_CORE). Now try again to enable it ;-)
Code:
Device Drivers  --->
    Graphics support  --->
        Console display driver support  --->
            [*] Framebuffer Console support



BTW: It should be safe to enable also # CONFIG_AMD_IOMMU_V2 is not set

Thank you Pietinger

There is a chance that I, by mistake turned off TTY, it makes an awful lot of sense now that I see it. It is what we would all call a pretty silly idea :)

Thank you so very very much, both for the help and the great resources, going through your kernel wikis now, great stuff
