 Posted: Sun Nov 26, 2023 9:03 am Post subject: [SOLVED] Black screen after loading i915 on Dell D630. |
 |
|
I'm trying to run Gentoo with Bcachefs on Dell D630. Using Live GUI I prepared basic system with Bcachefs support on a thumb drive with Bcachefs support (kernel from kernel.org) and using it I installed Gentoo on Bcachefs into Dell's SSD. My main problem is black screen moment after boot. After a little of investigation I found that loading i915 causes black screen. Right now kernel command line is:
| Code: | | BOOT_IMAGE=/vmlinuz-6.7.0-rc2 root=/dev/mapper/vg_nugget-gentoo ro rootfstype=bcachefs modprobe.blacklist=i915 video.allow_duplicates=1 console=ttyS0,115200 |
When I try to modprobe the module using serial console I get blackscreen and this:
| Code: | root@nugget ~ # modprobe i915

PS in Live GUI i915 works correctly.
#EDIT
I connected external monitor, in case there is a signal, but signal wasn't detected.

I was missing CONFIG_FB_VESA. It was hidden because CONFIG_FB was set to module, instead of built-in and CONFIG_X86_INTEL_LPSS, but it didn't help. I also tried to built i915 in.
config: https://pastebin.com/dEmuS0Q0 |

I would try:
1. Only to be on a safe side enable: # CONFIG_FB_SIMPLE is not set
2. Its okay to enable this static: CONFIG_DRM_I915=m
3. Remove: modprobe.blacklist=i915 video.allow_duplicates=1 console=ttyS0,115200
4. I have seen this is a very old Intel Notebook without EFI and without USB 3 having an old PCH, so you will need (this is maybe a / one reason of your problem) the first option, and maybe one of the others; Enabling (static) all 3 doesnt hurt:
# CONFIG_LPC_ICH is not set
# CONFIG_MFD_INTEL_LPSS_ACPI is not set
# CONFIG_MFD_INTEL_LPSS_PCI is not set
5. Maybe you will need also those enabled:
# CONFIG_INTEL_IOMMU_DEFAULT_ON is not set
# CONFIG_IRQ_REMAP is not set
-------
Not related to your problem:
I would enable both static:
CONFIG_BCACHEFS_FS=m
# CONFIG_BCACHEFS_POSIX_ACL is not set
Think about:
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
# CONFIG_INTEL_IDLE is not set
CONFIG_DEFAULT_MMAP_MIN_ADDR=4096
(You know that this kernel version has no support from Gentoo because it is a rc-kernel?)

| I did everything from your post one by one to know what is the problem, but it still doesn't work. I know this is rc kernel, I many times use them strait from kernel.org to test new features and never had problems with them. I tried sys-kernel/gentoo-kernel-bin-6.6.3 and it loads i915 correctly. Also, my USB to serial converter died, so I can't temporarily use serial console. |

| Found it! I was missing CONFIG_DRM_FBDEV_EMULATION. |

Ouch ... I must admit that I did not check this section in your .config (because this parm is normally enabled by default) ...
