[SOLVED] Black Screen, Plasma 5 & Nvidia Optimus

[Xywa]

Hi,

Since I have moved into Plasma 5 (beginning of February 2016) I cannot run Plasma 5 with Nvidia Optimus (as I can only use Intel). With Nvidia I have infamous black screen.

I have tested many xorg-servers, nvidia & intel drivers (older & newer) - nothing works

I posted a bug Xorg buglist a month ago - no answer:
https://bugs.freedesktop.org/show_bug.cgi?id=94577

I posted a bug on Nvidia list a month ago - no answer:
https://devtalk.nvidia.com/default/topi ... a-optimus/

I have consolekit with runleveldefault:
https://forums.gentoo.org/viewtopic-t-1 ... ight-.html

The only error I have looks like Gentoo related (no other Linux distros had such error):

Code: Select all

(EE) modeset(G0): failed to set mode: No space left on device

[asturm]

It looks like a problem with your configuration...

[Xywa]

It looks like a problem with your configuration...

Right, but everything is like should be to the many (not only Gentoo) guides.

Where do you think I should ask for help if nvidia & xorg developers cannot fix it? Looks like something with modesettings, which is part of the kernel I think? So maybe on the kernel bugzilla, so someone could says what that error means:

Code: Select all

(EE) modeset(G0): failed to set mode: No space left on device

Or is there any website with linux specialist, so I could pay them for help to fix the problem? I know Red Hat has professional support, but I am not sure if there such service for Gentoo.

Just in case anyone flying by here would be able to help you, they'd need the full log to see what's going on and not just that one line, anyway.

@Xywa,

You're randomly posting on other peoples threads all over the place I notice!! However clearly Yamakuzure knows how Bumblebee works and has a working configuration. In fact I bookmarked this thread (you made a guest appearance on!!) about Bumblebee - as a useful overview of how the technology works... Just for my "academic reference" - as my laptop only has a Nvidia GPU available (the Intel Haswell GPU is not wired up/disabled).

I didn't take me much Google'ing to find that the xinerama is essential for dual-monitor setups (you only want disable Xinerama / not enable it in your /etc/X11/xorg.conf* files - as this X feature is obsolete)...

Why don't actually try following the suggestions Yamakuzure made in the thread I've linked to above??!! Communication is a two-way process - not just about asking your questions - it's about listening / reading / absorbing the replies!! Instead of scatter gun trying lots of different package versions - try to work to/ base off someone else's working setup... Bumbleebee / Primus setups are known to be very fragile and break easily (during updates)...
Yamakuzure referenced an old/ stable branch Nvidia driver x11-drivers/nvidia-drivers-358.16-r1 - so why not use this?

If you're not a naturally methodical person - then write down/ type-up notes as you go along... You mentioned using Bumblebee before - but admitted you couldn't remember much about your original set-up...

Also what's the output from:

Code: Select all

lsmod | egrep "(drm_i915|nvidia)"

Are you compiling the intel gpu kernel driver (drm_i915) as a module? Are you building the additional nvidia_drm and nvidia_modeset modules - if you are using the newer x11-drivers/nvidia-drivers package versions?

However I wouldn't recommend using bleeding-edge anything if you want to get a working Bumblebee/Primus setup working... You've got both a bleeding edge x11-base/xorg-server version and a bleeding edge x11-drivers/nvidia-drivers driver version in that Xorg log. Fine if you want to just use either an Intel graphics card or a Nvidia graphics card - just not together!! Also you probably don't want to be rolling on a such a new kernel version... Use an older one - so you've got more flexibility about what x11-drivers/nvidia-drivers you install (yes those unsupported kernel warnings are important)... Once you get a working Bumblebee setup you'd probably want to update the related packages step-by-step (gradually unmasking each one) - e.g. x11-base/xorg-server / media-libs/mesa etc. - to determine what is causing the inevitable breakage...

Also I'd definitely not recommend using the eselect-opengl implementation in my Overlay - which you asked about (on yet another - unrelated - forum thread)... That will (no doubt) break a Bumblebee-based setup (purely because I don't have the required dual-gpu hardware to test against).

You're randomly posting on other peoples threads all over the place I notice!!

Yes, I have got a graphic card I cannot use with Gentoo for the 3rd month now (which used to work for over 2 years), is it strange enough I am trying to find a solution?

Bumbleebee

I used to use Bublebee for over a year, but from December 2014 I managed to use Nvidia propriety driver – which was very useful eg. for packages with vdpau USE flag (video editing). OK, bumblebee was enough for gaming, but with Nvidia driver I have more advantages. As Bumblebee was not updated for a long I could not run it after February 2016 (I had no such problems in 2014). It used to work for me (Nvidia driver) for over a year till February 2016, so what the point not to use it anymore?

referenced an old/ stable branch Nvidia driver x11-drivers/nvidia-drivers-358.16-r1 - so why not use this?

This is the clue! I was testing everything back to xorg-server 1.17.4 with nvidia-drivers-358.16-r5 instead of nvidia-drivers-358.16-r1. I could not test xorg-server 1.16.4-r5 as there is a bug during compilation, but looks the light at the end of the tunnel.

With nvidia-drivers-358.16-r1 and xorg-server 1.17.4 - after startx command, I could see (and move) for 1 sec mouse coursor and the for abou 2 sec I can see KDE starting screen like this: http://www.techrapid.co.uk/wp-content/u ... _Right.png
When blue bar is in the middle, then I have infamous black screen.

The strange thing is, there are no errors or warnings in Xorg.0.log, so why I have a black screen?

Are you compiling the intel gpu kernel driver (drm_i915) as a module?

No, I compile intel driver as part of kernel.

Are you building the additional nvidia_drm and nvidia_modeset modules - if you are using the newer x11-drivers/nvidia-drivers package versions?

No, I don't think so. Should I? Is there any info about that?

Also you probably don't want to be rolling on a such a new kernel version... Use an older one

Which one do you recomend? I was testing back to 4.4.6 without a success, maybe I will try again with nvidia-drivers-358.16-r1.

Hi,

Apart of previous post, I have some update.

When I create a new user with only .xinitrc in /home/newuser directory

Code: Select all

$ cat .xinitrc 
xrandr --setprovideroutputsource modesetting NVIDIA-0 
xrandr --auto 
exec startkde 

and after typing startx from the console
[1] I could see a working mouse pointer for a few seconds
[2] then KDE Plasma starting screen
[3] then KDE Plasma desktop - mouse and touch-pad doesn't work, but keyboard does. I could use start menu through Alt+F1, but after chosing any aplication I could see it on the task bar on the bottom, but I do not know how to open a window with it - so I could see through eg. konsole - so I could test if opengl nvida is working (by glxgeras or glxinfo command).

a) Does anybody know how to maximize such program from the task bar in KDE?
b) Or how to do mouse (or touchpad) working in my case?

When I reboot the computer, after typing startx, after KDE starting screen can only see black screen, with working mouse pointer only on the egde of the screen about 1 px (up and down). Removing all the old files from the account makes KDE working as in example above...

[Xywa]

Ladies and Gentelman,


After 4 months nearly at the end, ONE more things to resolve - but Plasma 5 works finally with Optimus (on 1 account only), but I need your help with last problem (bellow).

Bellow are also my tips (apart from previous posts) for other users struggling with Optimus and what I did:

[1] Try it on new user account:
There was a clue on Arch forum called "Clean cache (KDE) to resolve upgrade problems".
https://wiki.archlinux.org/index.php/KD ... e_problems
- As I described in post above, in main account, after "startx" I could see only KDE login screen for few seconds, and then infamous black screen.
- Also in previous post I said, that with new account, I could finally start KDE, but I did not see mouse-pointer. In reality, the mouse-pointer was on the righ edge of the screen, looks like there was another "virtual" screen, next to right-side of my laptop screen. I could see it for a moment on the edge (when I was moving a mouse), and sometimes I could even move a window from this area outside a laptop screen into a screen.

[2] Check user groups
- So I decide to make a video, as explanation above looks bit complicated, so I decided for video purpose to create another new user (by 'useradd') just for video purpose. After that I could not a start KDE, so I though maybe I need to check the groups. So I added this user after 'useradd' to such new groups: wheel, audio, video, cdrw, users, portage, polkitd, gamestat. After 'startx' I had... !!!working KDE Plasma5 with Optimus!!! Tested with games on Steam

But in my case...
I would like to check it and replicate on my 2 old user accounts, so I did changes in groups of one of old user, startx... and again I could see desktop and mouse-pointer only on the egde...
So for the test purpose, I created a new user, replicated everything and the same
I was trying to remove everything inside such testing user /home/directory apart .xinitrc - the same So I thought, what I did before so on ONE account it works? I switched into X11 Open GL, started KDE, chenged settings [Dispaly Monitor] > [Compositor] > [Rendering Backend] from 2.0 into 3.1 (like in working account), switched into Nvidia Open GL, and the same

So for another test, I copied all the files form working account into the any other, renamed it, 'startx' and... KDE Plasma 5 works just fine

^^ So looks like I press something on keyboard or a mouse (when this working account for a moment had no mouse-pointer), did something for this one account it works. Any old one, any any new one does't work... Any idea for the fix this really last problem?

Also pay attention to this bug https://bugs.gentoo.org/show_bug.cgi?id=571358
Every time after sddm gets reinstalled your Plasma5 with optimus won't be able to start, as /usr/share/sddm/scripts/Xsetup is not protected and gets rewritten.

Thank for the info.
For luck, I do not use sddm

Some update, May 28th, 2016 - after long battle (4 months) I decide on the same laptop with Optimus to check stable Gentoo AMD. On my other hard drive with 4 old ~amd64 I did manage (only on 1 account) to run Plasma 5, on others I cannot see mouse-pointer >> this is not resolved yet (see 2 posts above). On my new hard drive, I have fresh just installed Gentoo amd64, the same packages (kernel, xorg-server, nvidia-drivers, settings) and... black screen

Hi,

Today's experiment.

- The same laptop
- 2 identical hard drives, one with 4 old ~amd64 Gentoo, second with new amd64 gentoo
- the same kernels, the same kernel's config & drivers, the same X related files (and versions): xorg-server, xorg-drivers, xf86-input-evdev, xf86-video-intel, nvidia-drivers
- the same groups

In one case plasma 5 works, in second case "black screen".

Maybe you can find the reason? Both listings of configuration in 2 posts above.

The only difference I can see is;
- plasma 5.5.5 and plasma 5.6.4
- lspci -v (in working case shows)

Code: Select all

Kernel driver in use: nvidia
        Kernel modules: nvidia_drm, nvidia

in not working case:

Code: Select all

Kernel driver in use: nvidia
        Kernel modules: nvidia 

[Xywa]

Some update,

In my case (new amd64), I needed missing:

Code: Select all

*  x11-apps/xrandr
      Latest version available: 1.4.3
      Latest version installed: 1.4.3

Thanks to that, Plasma 5 startx with Nvidia Optimus but
1) The same problem like in old ~amd64 Gentoo, mouse-point out of screen, a little bit on the edge, but this time all the windows are on the desktop, so using keyboard, I have check Nvidia works just fine - only problem mouse-pointer out of screen.
2) I was trying to copy those one working account form ~amd64 and newer Plasma into a new system, this time Plasma crashed, but I could see mouse-pointer.
3) I cannot replicate working Plasma 5 on new system to any other user, I could see some windows but black screen instead of desktop. I think I should switch rendering from XRender into OpenGL but I cannot:
https://forums.gentoo.org/viewtopic-t-1 ... ight-.html
I did manage for one of the account but I cannot replicate it to another accounts

Many thanks to any ideas.

Another problem SOLVED - mouse & windows (Plasma 5.5.5 & Plasma 5.6.4) out of desktop.
Problem description: https://www.youtube.com/watch?v=J3IazDO ... e=youtu.be

Thanks to this post from to 2013:
https://devtalk.nvidia.com/default/topi ... tor-setup/

I added:

Code: Select all

Option "ConstrainCursor" "no"

To the Screen or Device section of /etc/X11/xorg.conf

Thanks to that, I finally had mouse on the screen, but clicking any aplication form KDE menu, open this application in the window outside laptops screen.... The same happed for my old ~amd64 Gentoo with Plasma 5.6.4 and a fresh amd64 Gentoo with Plasma 5.5.5, so definitely is not my config related, rather Gentoo or KDE related.

But I found a workarround.
Go to [System Settings] >> [Dispaly and Monitor] >> [Display Configuration] and the clinck on [Unify Outputs] and [aplly] - that's it! Clicking later on [Break Unified Output] and [Unify Outputs] again do not broke the system again.
!!! ^^ As any new windows eg. [System Settings] go outside laptops screen, as second workaround you have to drag and move by mouse an [System Settings] icon into desktop, then click that icon so new window will open on visable screen (so you could do above workaroud), clicking [System Settings] from KDE menu will open window in unvisable desktop. !!!

There is sometimes strange behavior with activities, but I need some more test.

Anyway, Nvidia Optimus and KDE Plasma 5 thanks to that works!!!!!!!!
The only unsolved problem for Today (30.05.2016) is this:
https://forums.gentoo.org/viewtopic-t-1 ... ight-.html
^^ as KDE accout has to be set to any OpenGL and GLX, without that Plasma crashes.

appendix:

Option "ConstrainCursor" "boolean"

When this option is enabled, the mouse cursor will be constrained to the region of the desktop that is visible within the union of all displays' panning domains in the current MetaMode. When it is disabled, it may be possible to move the cursor to regions of the X screen that are not visible on any display.

Note that if this would make display's panning domain is inaccessible (in other words, if the union of all panning domains is disjoint), then the cursor will not be constrained, so that it is still possible to move the cursor to each display.

This option has no effect if the X server doesn't support cursor constraint. This support was added in X.Org server version 1.10 (see “How do I interpret X server version numbers?”).

Default: on, if the X server supports it. The cursor will be constrained to the panning domain of each monitor, when possible.

[EXPERIMENT no.3]
[31.05.2016]

As my KDE Plasma 5 finally works with Nvidia Optimus with this minimum requirement bellow and without glamor USE flag (as Nvidia says so):

x11-base/xorg-server
Latest version installed: 1.17.4
* x11-base/xorg-drivers
Latest version installed: 1.17
* x11-drivers/xf86-input-evdev
Latest version installed: 2.9.2
* x11-drivers/xf86-video-intel
Latest version installed: 2.99.917-r2
* x11-drivers/nvidia-drivers
Latest version installed: 358.16-r1
* x11-apps/xrandr
Latest version installed: 1.4.0

I started (as I had some problem with few games from steam) testing some newer parts. So in my case, system also works with: x11-drivers/nvidia-drivers 361.28 and 364.19 and: x11-apps/xrand 1.5.0

So looks like, to have working Plasma5 & Optmus when you have minimum requirement above, the first step is to go into KDE setting (urgent >> in xorg-x11 OpenGL mode at the moment), check if you have in KDE [System Settings] >> [Dispaly and Monitor] >> [Compositor] >> [Renedring backed] into OpenGL (NOT XRender), and OpenGL interference into GLX (NOT EGL). If you have NOT, please switch into those options >> [Aplly], close [System Settings] window and the open again, if you see those changes, you could log off, switch into Nvidia OpenGL, startx again and it should work. If you cannot do changes, track this post: https://forums.gentoo.org/viewtopic-t-1 ... ight-.html

When you finally start KDE Plasma 5 with Nvidia Optimus OpenGL, and you have mouse pointer out of desktop, you have to add:

Code: Select all

Option "ConstrainCursor" "no"

to the Screen or Device section of /etc/X11/xorg.conf, and read more in few post above.

In any problems, send me a message or post here, as after 4 months my Plasma5 & Optimus finally works, and I have spent loots of time to sort it out

[EXPERIMENT no.4]
[13.06.2016]

Different nvidia-drivers tested.

Hi,

During last weekend I tested different x11-drivers/nvidia-drivers
From stable: 355.11-r2 To latest unstable: 367.18

With all of them my Nvidia Optimus system works fine (configures in post above). So as on my other user account plasma crashes during start, it looks like this is some king of config reason. Probably default settings in [System Settings] >> [Dispaly and Monitor] sections make this problem, as I manage (but only on one account) to have fully working Nvidia Optimus system. Other users (just created by adduser), with the same groups like working user, cannot use Nvidia Optimus and Plasma 5 (plasma crashes).

[Xywa]

I am much closer to solve mysterious black screen & Plasma 5

What we know. It affects only laptop users with Nvidia Optimus. As I found few post before, switching off VGA-0 and keeping Laptop Screen make the Plasma works. But as few games froem steam do not work with Plasma 5 (80% works just fantastic with Nvidia support with newest drivers), so I started to watch what is going on on console.

Code: Select all

displaymanager : xrandr version warning. 1.4
client has 4 screens
displaymanager screen (0)(LVDS-1-0): 1600 x 900

It looks like apart laptop screen, there is another virtual or more which is messing with the system. There is a button on my laptop Fn + F7, when I could switch into external VGA? probbably (so the screen is black on my laptop), another switch gives me Plasma 5 desktop but differnt on with differnet wallpaper. So i somone has a black screen and proper configuration, try to switch VGA <-> laptop screen button, maybe there is everyting fine, just default KDE configuration is sending the output into external VGA not laptop screen

client has 4 screens
^^this problem affect linux palyers with different distro but only with Nvidia Optimus

I could confirm, this is not because Nvidia Drivers. I tested all of them and now use 367.27 = no problem at all with working games (+ few more options in few games in compare to stable.

I have Dell XPS 15 (Intel and Nvidia GTX 9600) and usually I use nvidia for CUDA and for OpenGL Intel gpu. But tried to switch OpenGL, rebooted and viola I am in the same situation, black screen, just curzor blinking in top-right corner.
