PostPosted: Fri Nov 21, 2014 6:21 pm    Post subject: problems setting up hybrid graphics Reply with quote

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

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:

I also tried this xorg.conf out

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"

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 :D, 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

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

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:
Code:
 ~ $ optirun glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: Quadro K2100M/PCIe/SSE2
276.954538 frames/sec - 309.081264 Mpixels/sec
282.511501 frames/sec - 315.282835 Mpixels/sec
277.820893 frames/sec - 310.048117 Mpixels/sec
 ~ $ primusrun glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: Quadro K2100M/PCIe/SSE2
392.034528 frames/sec - 437.510533 Mpixels/sec
406.329255 frames/sec - 453.463449 Mpixels/sec
399.765486 frames/sec - 446.138282 Mpixels/sec
As this is a laptop, I am using the nvidia card only for wine applications, steam apps and vmware workstation when on AC power.

But: If you use primusrun and your application/game uses VBLANK, then primus shouldn't blank, too. In that case (highly degraded performance is an indicator) you should start your game with:
Code:
 $ vblank_mode=0 primusrun <your game here>
I had this with Mass Effect 1. Only ~10 FPS with nvidia and ~40FPS with intel. Now I am on ~60 FPS with nvidia. (Full screen 1920x1080, full details, full effects, anisoptric filtering enabled)

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

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:

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

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

It does utilize it or it would not work at all. My bet is a vblank conflict. Both primus and the application wait for vertical blank. Try with "vblank_mode=0" and with deactivated vertical blank in your application. And maybe take a look into driconf.

Try the following:
Code:
LIBGL_ALWAYS_SOFTWARE=1 glxgears

That shows how fast glxgears runs when your driver setup is broken, as software rendering ignores vsync. You can compare other things to that to know when it's working right.

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.

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.

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