Hello. I've got a problem with old laptop. I am botting with nomodeset by default, booting without results in screen artifacts like these - tty spawns in weird place and top of the screen has a piece of startup info:

Running startx with nomodeset does not work, and without it it clogs the laptop. I am pretty sure it is a hardware problem (getting bios boot error "data configuration read error") but i have no clue how to debug it and find out the faulty component. I thought the graphics card is broken but both bios and lspci shows the geforce G 105M card. What steps should i take to resolve the issue or at least know the source of the problem?

tgq,

Is this with your install media or have you booted into your install already and the problem you describe is with your own Gentoo install?

This is on the install. I've had similar problems with debian on this laption before so it's a broader issue i guess

tgq,

Please post or pastebin tho output of
Code:
lspci -nnk
so we can see the hardware on the PCI bus.

Running Xorg, twice, once with nomodeset and once without, then putting the corresponding /var/log/Xorg.0.log files onto a pastebin will be useful too.
These logs are too big for a post.

From your image, its not possible to rule out a hardware problem but the image fragments are too good to make it likely.
I'm tempted to say boot up, configure and start ssh, then install remotely and we will sort this later but it could be a waste of time if it is a hardware problem.

lspci --nnk

Xorg.0.log from startx with nomodeset

https://pastebin.com/i6pwbSmf

without nomodeset, laptop stops responding, that's the log after restart (there is a bunch of NULs at the end of logfile, like 50 of ^@^@^@^@^@ in vim)

tgq,

Code:
[    55.310] (EE) [drm] Failed to open DRM device for pci:0000:01:00.0: -19
[    55.310] (EE) open /dev/dri/card0: No such file or directory


That's a bit missing from your kernel, or a bit extra that stops direct rendering from starting.

The nouveau wiki page tells what you need but omits to say to turn off all the frame buffer drivers except VESA Framebuffer and Simple Framebuffer. They will only be used as fallbacks. Once direct rendering works, you will get a framebuffer console provided by the nouveau kernel module.

A kernel build will take a while on that system. Pastebin your kernel .config file if you want it looked over before your build.

From your lspci
Code:
00:05.0 IDE interface [0101]: Silicon Integrated Systems [SiS] SATA Controller / IDE mode [1039:1183] (rev 03)
    Subsystem: CLEVO/KAPOK Computer SATA Controller / IDE mode [1558:0802]
    Kernel driver in use: sata_sis
    Kernel modules: sata_sis, pata_acpi, ata_generic
Do not use IDE mode. Its crippled performance wise.
Its original purpose was to allow Windows Vista and XP users to install Windows, then add the SATA driver later, then switch out of IDE mode for good.
In IDE mode, SATA chipsets are often restricted to PIO mode, which forces the CPU do do all the data transfer. That's slow.
Less important on a laptop, the number of drive ports that can be used is restricted too.
