After last days drivers update (both intel & nvidia) I have such error on the screen after typing 'startx' from the console:

Have the same problems with xorg-server-1.18.2 and nvidia-drivers-364.12-r1. Blackscreen without blinking cursor instead of sddm login screen. "[ 8.398] (WW) NVIDIA(0): Unable to get display device for DPI computation." in the Xorg.0.log

It used to work with 1.18.1 (or .0, i don't remember) and one of older version of nvidia-drivers though.

If I remove nvidia.conf and change opengl to xorg-x11 I'm able to login to plasma and everything works without problems. But with nvidia/opengl only blackscreen istead of login screen.

nvidia.conf

I did rebuild system without xinerama, did not help.
I will try to rebuild all the system to see if it help.

Full rebuild with or without xinerama didn't work for me as well

All right I made nvidia+opengl work at last. GeForce 730M, Thinkpad T540p laptop.

x11-drivers/nvidia-drivers-358.16-r5 #downgrade
x11-misc/sddm-0.13.0-r3
sys-kernel/gentoo-sources-4.4.1

Great news! I will try this config, but at the moment I am in the middle of rebuilding all the system. 744 out of 1274 files so far

Right, I wrote on Nvidia forum, maybe they will help.

But I would like to check something.

Nvidia says: A Linux kernel with CONFIG_DRM enabled and the appropriate driver interfaces present
http://us.download.nvidia.com/XFree86/Linux-x86_64/361.28/README/randr14.html

Where should I find those drm_gem_prime_export, drm_gem_prime_import... ?

I finally got it working.

I have the latest programs.

x11-base/xorg-server-1.18.2
x11-drivers/nvidia-drivers-364.12-r1
x11-misc/lightdm-lightdm-1.17.5
sys-kernel/gentoo-sources-4.5.0

I recompiled intel with uxa after i read this thread ( thanks for the tip Xywa) [url] https://forums.gentoo.org/viewtopic-t-1042216.html

I create two xorg.conf-files one for intel and one for nvidia and they look like this.

xorg.conf.intel

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
Option "TearFree" "true"
EndSection

-------------------------------------------------------
xorg.conf.nvidia

/etc/X11/xorg.conf
Section "Module"
Load "modesetting"
EndSection

Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:4:0:0"
Option "AllowEmptyInitialConfiguration" "on"
EndSection

And i eselect opengl set xorg-x11.

I also have in grub.
GRUB_CMDLINE_LINUX="root=/dev/sda3 quiet nvidia_drm modeset=1"

glxgears show 60.425 FPS

Hello. Same issue here.

xorg.conf
xorg.log
dmesg
.config
lspci
grub.cfg

After xorg starts I see only black screen with back lighting. I tried different configurations but still can't get what's wrong.

I'm confused with lines

FINALLY got my optimus working again for the first time since -- sheesh I can't even remember, same story, worked, upgrade, broke.

I had the black-no-blacklit screen problem, accompanied by the no space left on device problem with the /etc/X11/xorg.conf.d/20-nvidia.conf file from the Gentoo Optimus Wiki page.
Setting xrandr --listproviders > xrandrproviders and xrandr --listmonitors > xrandrmonitors in ~/.xinitrc would reveal both providers and 0 monitors.

(credit where do, big thanks go out to the guys on tis list) ... From this list post: https://bugs.freedesktop.org/show_bug.cgi?id=94577

Enabling te glamor USE flag in make.conf and doing an emerge --deep --newuse @world did the trick! Finally hybrid graphics again yaay I would be happier If I had slept better since I decided to work on this old problem of mine again

TURNS OUT IT WAS IN THE WIKI HOLY COW - that light blue note was just completely invisible to me for some reason. There go a few days of my life for no good reason. Lol

My versions:

Tried to enable glamor. Still get the black screen, but found some interesting things.

First. If I make startx from user, it starts! But xrandr says I have only two possible resolutions (640x480 by default):

I had the same issue, but for another reason.

In my case, I used a display manager with an Xsetup config file not under /etc (but under /usr). The display manager's update caused the (previously working) Xsetup file to be silently removed, which caused the xrandr commands not to be executed anymore. The result was the described black screen at login and the

Also enabling aggresive PCIe power management on Optimus systems can result in blank screen even if the rest of the configuration (xorg.conf, gdm/xdg autostarts) are OK.
"pcie_port_pm=off" kernel parameter can help.

I've written an article on how to configure bumblebee on gentoo linux on my website and I'm constantly updating it (hopefully will add it to the gentoo wiki once I confirm it's 100% working), you may want to check it out:

https://www.dotslashlinux.com/2017/06/04/setting-up-bumblebee-on-gentoo-linux/

A couple of users have found it helpful, give it a shot and tell me what went wrong

Good Luck
