 |
|
Hello guys, i encountered some problem when mannully compiling the linux kernel.
Issue
The kernel can be booted successfully (I can find the dmesge log when i using livecd to find what happended) but No console and display . I think it might be framebuffer qeustion . like:
[url] https://forums.gentoo.org/viewtopic-t-1164907-highlight-loading+init.html [/url].
But I also set CONFIG_FB_* in my config file like below:
| Code: |
livecd /gentoo/usr/src/linux # cat .config | grep ^CONFIG_FB_
CONFIG_FB_VGA16=m
CONFIG_FB_UVESA=m
CONFIG_FB_VESA=y
CONFIG_FB_EFI=y
CONFIG_FB_VIRTUAL=m
CONFIG_FB_CORE=y
CONFIG_FB_NOTIFY=y
CONFIG_FB_DEVICE=y
CONFIG_FB_CFB_FILLRECT=y
CONFIG_FB_CFB_COPYAREA=y
CONFIG_FB_CFB_IMAGEBLIT=y
CONFIG_FB_SYS_FILLRECT=m
CONFIG_FB_SYS_COPYAREA=m
CONFIG_FB_SYS_IMAGEBLIT=m
CONFIG_FB_SYS_FOPS=m
CONFIG_FB_IOMEM_HELPERS=y
CONFIG_FB_MODE_HELPERS=y[/b]
|
I aslo set the CONFIG_*CONSOLE
| Code: |
livecd /gentoo/usr/src/linux # cat .config | grep ^CONFIG_*CONSOLE
CONFIG_CONSOLE_TRANSLATIONS=y
CONFIG_CONSOLE_LOGLEVEL_DEFAULT=7
CONFIG_CONSOLE_LOGLEVEL_QUIET=4
|
My Desktop Hardware Information
1. CPU: Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz
2. GPU0: Intel Corporation UHD Graphics 620
3. GPU1: NVIDIA Corporation GM108M [GeForce 930MX] (When config kernel i doesn't configure nvidia gpu driver)
4. SCREEN: eDP screen , xorg info : https://pastebin.com/5EaeGifQ
Things I have tried
1. Try to configure I2C driver
2. Switch EFI to BIＯS boot
3. Add framebuffer config copyed form genkernel config file.

I would add you don't need the agp stuff. Last I remember nvidia legacy driver 340.108 modified by shibotto needed it purely for compilation reasons and I don't think it was fixed. If that's not the case, you don't need it. It's ancient. AGP was a thing late 90's and early 2000's. It was something similar to PCI Express but it only had accelerated data flow in one direction - to the GPU, which was then called graphics accelerator because you couldn't program it.
Best Regards,
Georgi |
