Xorg black screen with nvidia optimus

deathangle908 · 2015-12-06 11:27:28

I just bought msi gs40 6qe. This laptop has skylake core i7 6700hq (which means integrated graphic HD 530) and discrete GTX 970. I'm struggling to start xorg. I wanna setup nvidia driver with modesetting as it's written on wiki Here's my xorg.conf As far as I understand modesetting should be provided by nvidia driver, but it's not there. Here're my xorg.log and dmesg

$lsmod |grep modesetting
#nothing
$pacman -Qs nvidia
libvdpau
nvidia
nvidia-libgl
nvidia-utils

What package should I install to get modesetting ?

I also tried intel driver but xorg can't find screens or it just writes "Waiting for connections" to output without even creating xorg.log.
I also tried nouveau with intel but it can't find screens too.
p.s. I'm running the latest archlinux with 4.2.5-1 custom kernel with this patch and no kernel params

[   292.977] (II) LoadModule: "modesetting"
[   292.977] (II) Loading /usr/lib/xorg/modules/drivers/modesetting_drv.so
[   292.977] (II) Module modesetting: vendor="X.Org Foundation"

Modesetting is an X11 module ( provided by the xorg-server package ) not a kernel module and the xorg.log shows it loading

Hm, right, but xorg exits right after start with "Server terminated successfully" I expected xterm to start, shouldn't it? If I start sddm it just hangs out with black screen.

How are you starting X when you expect the xterm to appear?

"Server terminated successfully"

Was not in the xorg.log you linked was the log truncated or was this in a different instance of xorg.log?

Finally make it work with intel drivers. Nvidia is still in blackscreen with desktop manager and quits right after start with startx

startx

I expect something to show because there's a default /etc/X11/xinit/xinitrc that should draw xclock and xterm.

It's printed to syserr (to tty)

I just got confused "modesetting" is in xorg logs indeed.

When I strart laptop and type "startx" for the first 2 times it exist and tells me that there's no provider with name modesetting. On 3rd time and other it doesn't show it. However xinit show everytime that there's no provider with name modesetting. As far as I understand modesetting is fine. It's another thing, I just don't know where to start. no errors in xorg, no errors in dmesg... I couldn't imagine that optimus is so hard to setup when I was told not to by nvidia laptop for linux.

Can you please post the console output from one of the failing runs of startx?
Also is anything being logged to ~/.xsession-errors?
Are xorg-twm, xorg-xclock and xterm installed?

Lone_Wolf · 2015-12-08 17:56:35

That error probably comes from an xrandr command like "xrandr --setprovideroutputsource modesetting" .

sometimes using names in those commands fails,and you need to use the numeric id instead.
when you got X started succesfully, run "xrandr --listproviders" to find out the id, then replace modesetting with the correct id and try if that solves the problem.

Well, starting X first and then setting provider from another tty changed everything. Now Screen goes totally black(no backlight), until I set provider from tty2, btw replacing it with ids listproviders has no affect Here're tty output and xorg.log At least I got something....
Here's xorg.log If i set modprovider in ~/.xinitrc and startx. Xorgs terminates with 0 right after start
Here's xorg.log with sddm and modeset in sddm/Xsetup - Scren goes black without backlight

deathangle908 · 2015-12-08 22:22:06

Hm, xinit doesn't tell anything about missing modesetting provider now, I have no idea what is changed....

Nope, there's no such file ;(

Yep

Please checkout the response I've written above.

Please don't do that.

There're mine configurations with the last archwiki update :

xorg.conf
As far as I understood modesetting is automatically loaded so I don't event need to put anything in ~/.xinitrc
I got xorg.log
And dmesg

Still getting the black screen without backlight with this configuration. Maybe this could be related with:

[  194.091495] [drm:intel_dp_aux_ch [i915]] *ERROR* dp_aux_ch not done status 0xad40001f

Lone_Wolf · 2016-01-04 13:22:36

Do those messages appear before or after X is started ?

After I type startx

Lone_Wolf · 2016-01-05 13:29:35

Did you add the xrandr commands to ~/.xinitrc as described in the wiki ?

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

Sure, I tried:

to start xorg and then set provider from another tty
put lines to ~/.xinitrc and start xorg
inject lines to sddm/gdm conf or another dm according wiki and run dm

Every attempt just ends up with blackscreen.

I've had the same issue since xorg-server 1.18 was released. I had to downgrade to 1.17 and IgnorePkg it as no suggestions yet have resulted in anything but a black screen.

mrunion · 2016-01-07 20:24:25

Is it this: https://bugs.archlinux.org/task/47151

This one is biting me. I had to go back to not using the nVidia card as the only card. I hate Optimus if the machine doesn't have the choice to shut off the Intel card.

So do I. But it didn't help,

tancrackers · 2016-01-28 17:35:13

Have you tried linux-lts with the paremeter:

i915.preliminary_hw_support=1

Also, linux-mainline helped me before, on kernel 4.4rc8
The new linux-mainline 4.5rc1 reinstroduced my problems, however.

NOTE: Linux-lts and skylake struggle with Plasma 5. Try another DE if you're a KDE user

EDIT: Note that I am now able to use bbswitch in combination with the blacklist to allow dynamic switch of GPU. More info on the forum post I link below.

I have the same laptop as the OP and was able to get two different configurations to MOSTLY work.

I first tried using Bumblebee following the wiki's guidelines. I eventually found that installing bbswitch would break the system and cause X to hang on boot.

This was an ok solution BUT it would keep the discrete GPU on and waste loads of power.

I next tried to experiment with a bunch of different setups. In the end I found that following the advice of the PRIME wiki page and Intel Graphics pages allowed me to (in a hacky way) disable the GPU when desired. I have more info on this setup here.

I am still on the lookout for a better solution as this still has its problems. (currently if I disable the GPU after X loads I can't shutdown gracefully.)

If someone comes up with a better approach for this system I would love to know more.

BTW. I haven't tried it yet but apparently there is a new BIOS update for the system. You can find it on the MSI website.
