problems setting up hybrid graphics

[Adel Ahmed]

I'm using a lenovo b5400 with:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/820M / GT 620M/625M/630M/720M] (rev a1)

I have successfully setyp the intel drivers and can start xfce
I have been trying to setup the hybrid graphic rendering to use nvidia's opengl and opencl, I have been using this document:
http://wiki.gentoo.org/wiki/NVIDIA_Driver_with_Optimus_Laptops
and
http://us.download.nvidia.com/XFree86/Linux-x86_64/331.38/README/randr14.html

I've tried both xorg.conf files, created the .xinitrc but all I get is a black screen, with and without slim(startx manually)
I've installed the nvidia-drivers package; I get this error all the time though:
ACPI Warning: \_SB_.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20140424/nsarguments-95)
don't know if this is related

thanks

[Adel Ahmed]

here's my /home/adel/.xinitrc:
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

my first xorg.conf:
Section "ServerLayout"
Identifier "layout"
Screen 0 "nvidia"
Inactive "intel"
EndSection

Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
EndSection

Section "Screen"
Identifier "nvidia"
Device "nvidia"
Option "AllowEmptyInitialConfiguration"
EndSection

Section "Device"
Identifier "intel"
Driver "modesetting"
EndSection

Section "Screen"
Identifier "intel"
Device "intel"
EndSection


the second one:
http://pastebin.com/zET9E0HY

[Adel Ahmed]

I also tried this xorg.conf out
Section "ServerLayout"
Identifier "layout"
Screen 0 "nvidia"
Inactive "intel"
EndSection

Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
EndSection

Section "Screen"
Identifier "nvidia"
Device "nvidia"
# Uncomment this line if your computer has no display devices connected to
# the NVIDIA GPU. Leave it commented if you have display devices
# connected to the NVIDIA GPU that you would like to use.
Option "UseDisplayDevice" "none"
EndSection

Section "Device"
Identifier "intel"
Driver "modesetting"
BusID "PCI:0:2:0"
EndSection

Section "Screen"
Identifier "intel"
Device "intel"
EndSection

but no dice

[Adel Ahmed]

help anyone?

[Adel Ahmed]

I'm giving up this method, ill be relying on switcheroo and bumblebee

bumblebee is great, I got 1200 FPs on glx gears instead of 60, I cannot run wine games however; says 32 bit opengl is not installed
I've also tried out nouveau, I'm getting 6k fps at the cost of not seeing the gears themselves , I'm working on it at the moment

I'll try nouveau first and then go back to bumble bee

I still need all the help I can get

[Adel Ahmed]

I have fixed nouveau rendering by enabling compositing, I'm getting 1500 FPS now, games are running with degraded performance!!!!!
I'll try getting back to nvidia-drivers

[Adel Ahmed]

help anyone?

[Yamakuzure]

nouveau can not handle 3D acceleration on new(er) cards and falls back to software rendering. Although I guess that your card should be supported.

However, the proprietary driver is much more painless with hybrid laptops.

If you use bumblebee, then try primusrun, too. (x11-misc/primus from the bumblebee overlay)

On my system with nvidia K2100M (quatro) I get:

[Adel Ahmed]

thanks, I've tried primus application;
primus can indeed run wine games but here's the problem:
$primusrun glxspheres64
Polygons in scene: 62464
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: GeForce GT 720M/PCIe/SSE2
62.419087 frames/sec - 53.947569 Mpixels/sec
60.007769 frames/sec - 51.863514 Mpixels/sec

$optirun glxspheres64
Polygons in scene: 62464
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: GeForce GT 720M/PCIe/SSE2
138.040458 frames/sec - 119.305607 Mpixels/sec


the same applies for game fps
did you have this problem too

[Yamakuzure]

No... That's weird. Are you running compiz?

Maybe some of the ideas here can help: Worse performance with nvidia gpu than with integrated intel.

Basically I used the archi linux guide on bumblebee to set up things and went the virtualgl way.

Oh, and I am using only the live ebuilds from the bumblebee overlay:

[Adel Ahmed]

Ok I unmerged my original bumblebee in favour of the layman one
the guide helped a little
I was looking at nvidia-config with optirun vs primusrun
optirun gpu utilization is 70%~ while the primusrun gpu utilization is 25%

at least that gives me a hint on where to look

I appreciate your help, any further help would be even greater

[Adel Ahmed]

I still have no idea why primus run cannot utilize the GPU, help anyone?

[Yamakuzure]

[Adel Ahmed]

now I get nothing when I run optirun glxgears:
adel@localhost ~ $ optirun -v glxgears
[ 56.338490] [INFO]Configured driver: nvidia

[Ant P.]

Try the following:

[Yamakuzure]

I just had a weird experience.

As I wrote, the performance in Mass Effect 1 was abysmal until I started with vblank_mode=0. Yesterday I tried a game and the performance was down the drain again. It appears that primusrun ignored the vblank setting, or something else enforced a vsync. I had to disable vsync in Mass Effect to get to the old performance.

There is either something wrong with my setup, but I didn't really change anything, or something in the bumblebee/primusrun/wine path is enforcing "outside" vertical sync no matter what.
I haven't figured out, yet, what it is.

sometimes I get this error in journalctl:

Huh? I got this too before I set my laptop to unload nvidia_nvu module before going to sleep. Do you hibernate your machine? removing the nvidia module and re-inserting it should fix that issue.

Oh, and I prefer glxspheres64 (comes with virtualgl) over glxgears.

[Adel Ahmed]

you're right, removing and reinserting the moddule helped, now back to debugging the primus run performance
