 Posted: Fri Nov 08, 2024 8:54 pm Post subject: Not getting a Framebuffer to use during boot |
 |
|
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,
Screen shot of the frame buffer settings:

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? |

If you enable this:
| Code: | General setup --->
[*] Configure standard kernel features (expert users) ---> |
there is a little trap 
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
(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
