Hello, I tried playing Kerbal Space Program for the first time in 2 years today on my desktop. I had abysmal performance despite having a newer video card. I realized I had the selected opengl to xorg-x11. I changed it to nvidia, logged out and restarted xdm and when the screens came back, they were blank, except I DO have a cursor moving around all 3 screens.

I tried using nvidia-xconfig to create an xorg.conf file and while it works as expected with xorg-x11, it has the same effects as no xorg.conf file with nvidia OpnGL setting.

I have had zero differences in log files between the working and non-working opengl setting, EXCEPT when opengl is nvidia Xorg.0.log shows the loading of the appropriate nvidia modules.

Ideas to troubleshoot?

@BlueFusion,

Hi I'm trying piece together why my SDDM setup and Plasma 5 don't play nice with the Nvidia proprietary drivers... I've found I have to enable gles2 and the egl USE flags on the Qt5 toolkit. That only got me a working SDDM - not Plasma 5 - with only EGL graphics acceleration support - not GLX. I've a Nvidia 970M graphics card with nvidia-drivers version 361.18. SDDM requires GL acceleration 2.0+ ... Basically something funky is going on - that is Gentoo specific...

What is the output from:
Code:
equery l -f -F'=$cpv:$slot' '^dev-qt/.*$' | awk '{ if ($0 ~ "\:5$") printf("%s\0", $0) }' 2>/dev/null | xargs -0 emerge --color=n -pv 2>/dev/null

Code:
eselect profile list

When run on your system?

Ta
Bob

I had the same issue, adding the sddm user to the video group fixed it until i restarted KDE then it just went blank again and wouldnt come back. I never bothered to try and resolve it (other than trying different driver versions), just installed lightdm. It is definately an issue with the nvidia drivers, though no version from 352->361 made a difference. It works fine on my laptop which uses the ati-drivers (fglrx).

That command needs to be run as root (cough, cough) 8)

Does Lightdm work with the nvidia/OpenGL? If so, I might switch to that.

I've no problem with you switching to LightDM... But I should point out that most other major distros (with a Plasma 5 spin) have working GLX acceleration and non-blank SDDM - when using the Nvidia proprietary drivers!! Thinking OpenSUSE Tumbleweed and Arch - both of which are also installed on my laptop. It's a definitely a Gentoo- specific problem!

Surely Plasma 5 will still limp along on EGL (only) acceleration - on your system - even if you switch to LightDM?

True, I will try to get SDDM working.

As if this isnt annoying enough as it is, another desktop of mine running almost identical software except older nvidia-drivers because it's an older nVidia card, runs SDDM with opengl in nvidia mode. I only use it for Kodi as an HTPC in my living room. Specs on that device as follows:

Core 2 6700
3GB RAM
Old ASUS mobo (forget model w/o cracking it open)
nVidia GeForce 8400 GS Rev. 3
4.1.12 kernel as 4.4.0 has an issue with routing tables which this device needs using OpenVPN

Note: All packages except nvidia-drivers are built on a single VM and all of these other devices use these packages, so other than nvidia-drivers, they are IDENTICAL between machines.

I should add, that from the SDDM greeter page, I log directly into a Kodi session as Plasma remains a blank screen upon login. But this is still better than what my other desktop can do...which doesn't even display the SDDM greeter (login) page.

I opted to just move away from nVidia proprietary drivers again and see how Nouveau has come over the past year since I've tried it.

Good news and bad news.

Good news: I can use Plasma on my HTPC with Nouveau. Everything seems to work fine. Cool!

Bad news: My main rig which is the topic of the original issue, loads SDDM login screen, but as soon as a press a key on my keyboard, SDDM freezes. The mouse works and I can click on stuff up until I press any key. I have to login via SSH to killall -9 X, sddm, sddm-greeter, and sddm-helper at which point it dumps some data. Here's a tidbit:

Since this is no longer specifically nVidia related, I'm going to open up a new topic to further investigate this issue and try to get it working. It's probably relating to the multi-head setup I have (2 screens and a projector)

@BlueFusion

OK,

So I've made some progress. Overriding the media/libs/mesa libGL.so with the x11-drivers/nvidia-drivers libGL.so library gets us much further forwards!! Very exciting times (IMHO) 8)

See my updated Gentoo bug report for further info!!

The media/libs/mesa libraries mask the x11-drivers/nvidia-drivers (as the Nvidia libraries are buried in a sub-directory)... However Qt5 depends on dynamically linking against the appropriate libGL.so.1 library!!
Code:
readelf -d libQt5Gui.so.5.5.1

Dynamic section at offset 0x4a0280 contains 34 entries:

I can post a little BASH script to change the library links - if you require and want to test this??!! Let me know!

Sure, I'd like to give it a try. Nouveau isn't working as well as I had hoped, either. The HTPC does have issues after all....

EDIT:

Dumb question, but regarding those libraries....you did run eselect opengl set nvidia right? I figure that's what should correct those libraries, but I can see how if it's not built against it, there could be issues....

@BlueFusion,

Code:
eselect opengl set nvidia

is quite limited in scope...

Take a look at:
Code:
equery files eselect-opengl
# Basically only this script file...
cat /usr/share/eselect/modules/opengl.eselect


The only files the module touches are:
Code:
/etc/env.d/000opengl
/etc/X11/xorg.conf.d/20opengl.conf


The Qt5 toolkit ignores the LDPATH env variable!! The media-libs/mesa GL libraries are not affected by the module either...

Interesting, I didn't look into it that much before, but definitely good to know.

Any other progress? I just got home from a trip and am going to see if I can get Nouveau to work. If not, than back to nVidia drivers and keep hacking away at that, I suppose.

@BlueFusion

I've got a fully working Plasma 5 Session - with all the associated bugs - but thankfully less of the Kwin 5 related ones I have previously (i.e. I now have full GLX compositing)!!

If you are feeling brave you could try testing the following (pre-patched) packages:
media-libs/mesa::bobwya
app-eselect/eselect-opengl::bobwya

from my Layman Overlay bobwya ...

Please also see the Gentoo Bug report "app-eselect/eselect-opengl with media-libs/mesa with x11-drivers/nvidia-drivers-361 - GLX not working(?)" (the name gets changed every few hours - not by me!! 8) ) for more information on the working USE flags for my system, etc.!!

Just remember to rebuild all packages depending on media-libs/mesa::bobwya !! Or the good ol'
Code:
emerge -uDN --with-bdeps=y --keep-going --backtrack=100 @world


I also am convinced that dev-qt/*:5 should have USE flag -egl (for the packages that have that USE flag). Otherwise they will statically link against the media-libs/mesa headers and break GL acceleration when using the x11-drivers/nvidia-drivers. To test this I'll need to re-emerge all these packages (plus Plasma 5 ones) with USE +egl to see if everything breaks again!! I do plan to try this today/ tomorrow (ish)...

Bob

I'm going to give this a test spin. Working on getting Nouveau removed and this stuff all installed again. I'll update after some testing.

Actually when I checked I've actually got the egl USE flag globally enabled with only the following override...
Code:
dev-qt/qtgui:5   -egl


So I'll try breaking my system again - by re-enabling that USE flag!! Hah hah 8)

Is there any good reason to have EGL support if gles/gles2 isn't used? From what I can conclude, EGL is just an API layer for GLES, which is primarily for embedded systems.

No of course not! In fact I think it's time to expunge that USE flag me thinks... 8)
It would be OK to enable that USE flag with FOSS graphics drivers that will render through mesa though - me thinks...

I also had forgot the hard (circular) dependency on GLESv2 opened up by enabling the +egl USE flag on dev-qt:gui5 (reference: dev-qt/qtmultimedia:5).
That's going to bugger up Qt5 GL handling for sure, see:
Code:
-opengl $(usex gles2 es2 desktop)

from the ebuild for dev-qt:gui5. So when the +gles USE flag is enabled the GL library search mode (for cmake) switches from a desktop profile to a mobile ES2 profile.

So I guess that's that (in terms of further testing). Good luck fixing your system - you've definitely got the right approach if you're not enabling the +egl USE flag!

At the moment, I have EGL enabled except for the package you mentioned above, as that's what I had previously anyway. I'm going to change that to a global -egl USE flag.

Currently, I finally have GPU rendering on Kerbal Space Program and Kodi in a Plasma session with your workaround!!!! Amazing difference in performance and CPU load.

What I'm still missing is things like the KDE desktop cube effect.

At the moment, I have EGL enabled except for the package you mentioned above, as that's what I had previously anyway. I'm going to change that to a global -egl USE flag.
Currently, I finally have GPU rendering on Kerbal Space Program and Kodi in a Plasma session with your workaround!!!! Amazing difference in performance and CPU load.
What I'm still missing is things like the KDE desktop cube effect.


@BlueFusion,
Well I'm fussy that way... I'm one of these shallow people that like all the Kwin Bling-Bling ... So that means Window Cover Switch, Blurred Transparency, etc. 8)
In fact I'm so anal about this stuff that I've processed all the stock Breeze theme widgets with Inkscape - to give them near full transparency :roll: Hey I can't help it! 8)

Now for the bad news... I don't normally use the Desktop Cube Effect - but enabling doesn't do anything - I'm "stuck" with the Desktop Slide effect... I bet if I logged into my Arch or Opensuse Tumbleweed installs (multi-boot) they would perform identically - it's possibly something that Martin Gräßlin hasn't yet fully baked... I'm doing all this testing on my laptop - which has a Nvidia Geforce GTX 970M graphics card - so if it's going to work...

It might help push things forward if you mention on my Gentoo bug report... app-eselect/eselect-opengl with media-libs/mesa with x11-drivers/nvidia-drivers-361 - GLX not working(?)
- that the "proof of concept" media-libs/mesa and app-eselect/opengl packages appeared to help with Plasma 5 GLX acceleration on your system... Nobody else has bothered / been able to do that yet - but my bug report has been renamed a few times... :cry:

I, too, love using the transparancy and wobbly windows and whatnot. I just wish wobbly windows and the desktop cube would work on my two nvidia-powered desktops. My Intel HD Graphics laptop has all of the working great.

I added my confirmation of the working patches to bugzilla.

That's odd - because wobbly windows are working or me... I'll double check whether the cube effect is working under Arch - a bit later on... Perhaps running the beta version of the x11-drivers/nvidia-drivers (358.18 I think) package would help you?

Thanks for commenting on the bug.... 8)

I found a useful blog post by Martin Gräßlin on this very issue (OpenGL vs OpenGL ES support in Kwin 5)...
