 Posted: Thu Oct 14, 2021 1:08 pm Post subject: Trouble setting up NVIDIA Optimus |
 |
|
I come once again, a humble student of the Gentoo, to seek guidance from the repository of knowledge known as the Gentoo Forums. (I am a little sleep deprived from fixing my install)
As the title reads, I have been having a lot of trouble trying to get NVIDIA Optimus to work on my MSI GS65 laptop. I have pretty much followed the wiki page NVIDIA/Optimus to the letter, including the section on using the EDID of the monitor. I have also looked at the documentation provided by NVIDIA, but to be frank their documentation hasn't been too uesful.
Currently, when I run startx the screen briefly flashes to a black screen before the X server terminates itself. There was an error message of sorts that just read
For clarity, I have twm and xterm installed, so the X server does have something to do when booted. Furthermore, I have added the necessary xrandr commands to ~/.xinitrc.
Here, is the log file from running the X server:
https://dpaste.com/F97B4JE3H
From reading through the log file, I am fairly certain both the NVIDIA GPU and Intel integrated GPU connected to the laptop monitor from the lines:
| Code: |
[ 2925.870] (--) NVIDIA(GPU-0): Sharp LQ156M1JW03 (DFP-0): connected
[ 2925.870] (--) NVIDIA(GPU-0): Sharp LQ156M1JW03 (DFP-0): Internal TMDS
[ 2925.870] (--) NVIDIA(GPU-0): Sharp LQ156M1JW03 (DFP-0): 165.0 MHz maximum pixel clock
|
| Code: |
[ 2925.928] (II) modeset(G0): glamor X acceleration enabled on Mesa Intel(R) UHD Graphics 630 (CFL GT2)
[ 2925.928] (II) modeset(G0): glamor initialized
.
.
.
[ 2925.937] (II) modeset(G0): Monitor name: LQ156M1JW03
[ 2925.937] (II) modeset(G0): EDID (in hex):

[ 2925.937] (II) modeset(G0): 004c513135364d314a5730330a2000e4
|
The one interesting I did notice is that it seems like the NVIDIA GPU connects to the monitor or at least brings up the monitor twice:
| Code: |
[ 2925.870] (--) NVIDIA(GPU-0): Sharp LQ156M1JW03 (DFP-0): connected
|
| Code: |
[ 2926.522] (--) NVIDIA(GPU-0): Sharp LQ156M1JW03 (DFP-0): connected
|
The error that seems to kill the X server is:
| Code: |
[ 2926.525] randr: falling back to unsynchronized pixmap sharing
|
but I have no idea what that means, and a quick Google search yielded no fruitful results.
Just in case, below are the links to my kernel config file and 10-nvidia.conf file:
Kernel Config: https://dpaste.com/A2R5M5W32
Xorg Config (10-nvidia.conf): https://dpaste.com/2WLJK8DGK
I would appreciate any guidance on this issue. Thank you in advance.

| Are you working to run the X server with Nvidia GPU only? if yes, why not disable the intel GPU in BIOS? It should make the Nvidia work properly even without the manual configuration. |

| Thank you for the reply. I would prefer to switch between my iGPU and NVIDIA card for battery reasons. Just out of curiosity, do you have suggestions regarding the pixmap thing? I'm not even too sure if that is the issue. |

Not sure I can be of much help, but are you sure you need to specify the EDID explicitly? I just did the following in Gentoo amd64 on my Clevo W230SS laptop:
1. Deleted the file /etc/X11/xorg.conf
2. Created the file /etc/X11/xorg.conf.d/01-nvidia-offload.conf containing the following:
| Code: | Section "ServerLayout"
Identifier "layout"
Option "AllowNVIDIAGPUScreens"
EndSection |
3. Performed the usual ‘emerge -uvDN @world‘ to update and upgrade any packages.
4. Removed all references to the libglvnd USE flag from /etc/portage/make.conf. The only place libglvnd is declared explicitly is in the file /etc/portage/package.use/world because I have a multilib installation:
| Code: | # grep libglvnd /etc/portage/package.*/*
/etc/portage/package.use/world:>=media-libs/libglvnd-1.3.1 abi_x86_32 |
5. I use LightDM and KDE so I deleted the line 'display-setup-script=/etc/X11/Sessions/plasma' in the file /etc/lightdm/lightdm.conf, and I deleted the script /etc/X11/Sessions/plasma because the xrandr commands in it are no longer necessary.
The command 'xrandr --listproviders --verbose' lists both the NVIDIA and Intel video devices:
| Code: | $ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x47 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 4 associated providers: 0 name:Intel
Provider 1: id: 0x203 cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:NVIDIA-G0 |
The default is to use the Intel IGP:
| Code: | $ glxinfo | grep -E 'OpenGL (vendor|renderer)'
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 4600 (HSW GT2)
user $ __NV_PRIME_RENDER_OFFLOAD_PROVIDER=Intel __GLX_VENDOR_LIBRARY_NAME=mesa glxinfo | grep -E 'OpenGL (vendor|renderer)'
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 4600 (HSW GT2) |
unless I use environment variables explicitly to specify that the NVIDIA GPU be used for a specific application:
| Code: | $ __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep -E 'OpenGL (vendor|renderer)'
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTX 860M/PCIe/SSE2 |
Performance is reasonable:
| Code: | $ __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia __GL_SYNC_TO_VBLANK=0 glxgears
27197 frames in 5.0 seconds = 5439.292 FPS
27332 frames in 5.0 seconds = 5466.274 FPS
27857 frames in 5.0 seconds = 5571.184 FPS
27553 frames in 5.0 seconds = 5510.447 FPS
27128 frames in 5.0 seconds = 5425.556 FPS
^C |
To run a program such as LibreCAD using the NVIDIA GPU I do the following:
| Code: | | $ __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia librecad |
I can connect an external monitor to the laptop via either VGA cable or HDMI cable and both methods work, and I can switch between the laptop monitor and the external monitor using KDE Plasma’s ‘System Settings’ > ‘Display Configuration’.

Thanks for you reply Fitz! Just for clarification, is the following code:
| Code: |
Section "ServerLayout"
Identifier "layout"
Option "AllowNVIDIAGPUScreens"
EndSection
|
all you have in your 01-nvidia-offload.conf file?
I will definitely try what you have done to see if that works. |

| Unless you want to use multiple monitor, you could simply run X with intel GPU and run program with "prime-run xxx" for better performance. Per my understanding, prime-run work the same way as Prime offload command as mentioned previously |

Yes, that is all the file contains.

| I would preferably use multiple monitors as I normally use an external monitor with my laptop at home. Does this set-up require the NVIDIA card handling the graphics? |

No, it does not require the NVIDIA GPU handling the graphics. See my first post for how to launch specific applications to use the NVIDIA GPU.
I also use an external monitor with my laptop at home and in the office. I normally have the display on the external monitor mirroring the display on the laptop's monitor and the laptop monitor disabled (i.e. turned off), but I can use both monitors simultaneously if I want, either with identical content displayed or with separate content displayed (i.e. a dual-monitor setup).

Is your laptop's HDMI wired to Nvidia card? The HDMI in my laptop is wired only to Nvidia card and connected monitor cann't be found by xrandr. Is it the same in your case? How did you fix it? Thanks |

Are you sure? My understanding is that the point of the NVIDIA Optimus design is that the NVIDIA GPU outputs via the Intel IGP display memory. Anyway, the following command outputs are from my NVIDIA Optimus laptop (Clevo W230SS, with both VGA and HDMI ports):

If I plug both the VGA and HDMI connectors from my external ViewSonic VX2363Smhl monitor into the VGA and HDMI ports on the laptop:
| Code: | $ xrandr --listmonitors
Monitors: 2
0: +*DP1 1920/510x1080/290+0+0 DP1
1: +HDMI1 1920/510x1080/290+1920+0 HDMI1 |
I can then switch between the two ports:
| Code: | $ xrandr --output HDMI1 --auto # Enable the HDMI output.
$ xrandr --output DP1 --off # Disable the VGA output.

I agree. But my xrandr only shows integrated LCD (eDP), if I load both AMDgpu driver and Nvidia driver. No other ports can be found in the output of xrandr. However, if I choose discreted GPU only in the BIOS. Then Nvidia GPU is used for both rending the display and other calculate. When I run xrandr, I can see other ports like HDMI, DP, etc... |

Looks like someone with your model of laptop would be more help. Have you tried the Arch Linux Wiki article on your laptop?:

Thanks. I saw this too. Unfortunately, my Laptop doesn't have thunderbolt. Both Type-C and HDMI are wired to Nvidia. I assume there is no other solution unless to use the nouveau or Nvidia can do something in their propriety driver. I am not sure if it is also the similar case for the dchoi2464 |
