This shajt ain't working and i'm losing my mind over it on vacation..

Hardware:
https://www.asus.com/us/ROG-Republic-Of-Gamers/ROG-G750JS/specifications/

Me crying

1. Look at the Nvidia page on wiki https://wiki.gentoo.org/wiki/NVidia

2. Find out that Open-source drivers are for plebs so you use Nvidia closed-source.

3. https://wiki.gentoo.org/wiki/NVidia/nvidia-drivers#Hardware_compatibility my driver is not legacy so i don't need to `Masking drivers with version higher than 174`

4. On gentoo x11-drivers/nvidia-drivers package is used to get closed source Nvidia drivers.

Kernel Configuration

5. Kernel Enable loadable module support is included
MTRR (Memory Type Range Register) support is included
VGA Arbitration is included
IPMI top-level message handleris included
/dev/agpgart (AGP Support) is not configured my system doesnt have it i believe.

KERNEL Disable support for the in-kernel driver.. IS SET

For (U)EFI systems, uvesafb will not work.

.config has:

# causes intermittent problems with the initialization of the NVIDIA drivers. There is no known alternative framebuffer for (U)EFI systems. https://wiki.gentoo.org/wiki/NVidia/nvidia-drivers
CONFIG_FB_EFI=n

6. kernel 4.19.0 is used

stub title

7. VIDEO_CARDS="nvidia" is in make.conf

8. zgrep "CONFIG_MODULES=" /proc/config.gz outputs CONFIG_MODULES=y

9. /etc/modules-load.d/nvidia.conf contains nvidia

10. rc-update add modules boot outputs * rc-update: modules already installed in runlevel `boot'; skipping.

11. /usr/share/doc/nvidia-drivers-343.36/README.bz2 is not present less /usr/share/doc/nvidia-drivers-343.36/README.bz2 outputs sh: /bin/zsh: No such file or directory /usr/share/doc/nvidia-drivers-343.36/README.bz2: No such file or directory

12. http://us.download.nvidia.com/XFree86/Linux-x86_64/343.36/README/optimus.html is useless.

EDID

I have no idea what EDID is.. Google+Wiki is not helpful.

Ensure the currently running kernel has CONFIG_I2C_CHARDEV enabled and the resulting i2c-dev module loaded or compiled monolithically for read-edid to work. -- https://wiki.gentoo.org/wiki/NVIDIA/Optimus#Using_a_specific_monitor_via_EDID

  1. CONFIG_I2C_CHARDEV is not set >> CONFIG_I2C_CHARDEV=y

and the resulting i2c-dev module loaded or compiled monolithically for read-edid to work. -- https://wiki.gentoo.org/wiki/NVIDIA/Optimus#Using_a_specific_monitor_via_EDID

No idea what that means.. Added stub to wiki entry.

Some laptops/notebooks may benefit from saving the EDID screen information to a file so it can be passed to the Intel modesetting driver. The EDID information can be saved using the read-edid utility. -- https://wiki.gentoo.org/wiki/NVIDIA/Optimus#Using_a_specific_monitor_via_EDID

Invoked emerge --ask x11-misc/read-edid i guess?

/etc/default/grub has

# Note that you can use only modes which your graphic card supports via VBE.
# You can see them in real GRUB with the command `vbeinfo'.
GRUB_GFXMODE=1920x1080

EDID Xorg.conf

EDID Xorg.conf Example https://wiki.gentoo.org/wiki/NVIDIA/Optimus/EDID_Xorg.conf_Example

I have no !@#$% idea what to do with it..

Before starting X

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

is required.. added to /home/kreyren/.xinitrc

NOTE: If you get a black screen with no back-lighting from the previous steps, creating .xsessionrc and placing the xinitrc commands in there COULD fix it.

Use the xrandr command to find the appropriate graphics device: root #xrandr --listproviders

Noted..

Display manager configuration

Added CONFIG_PROTECT="/usr/share/sddm/scripts/Xsetup" to make.conf

Issues

using dwm after startx is invoked the tty returns following error:

Noticed that nvidia-drivers didn't pull the USEFlags.. emerging (special thanks to Mysic on IRC)

New result https://imgur.com/a/anRIyBh

none wants to help me trying to downgrade to stable.

Suspect bug..

Created bug #669826

Give up for today.. spend 3 days with it so far.
