 Posted: Tue Feb 18, 2014 9:11 am Post subject: Nvidia Optimus and X server configuration still failing |
 |
|
Hello everyone,
in my laptop I have an optimus setup. When trying to start the x-server without using a xorg.conf, everything works more or less fine - of course, just the intel card is recognized. (xrandr just lists intel as a provider)
When I try setting up the xorg.conf according to a lot of websites dealing with the same issue, I can't get the x-server to run.
I get the following message: Screen 0 deleted because of no matching config section.
The Xorg.0.log:
http://paste.org.ru/?qd3uwn
My xorg.conf:
http://paste.org.ru/?700nrc
lspci output:
http://paste.org.ru/?mlb5cj
lsmod output:
http://paste.org.ru/?djvuvv
Setting in make.conf
VIDEO_CARDS="nvidia intel modesetting"
I already tried running nvidia-xconfig and uncommenting Option "UseDisplayDevice" "None" but to no avail, searching the internet up to now wasn't successful either.
I hope it just is a trivial issue where I am just missing something but still - help would be really appreciated 
Thank you very much in advance!

Are you sure you don't want intel driver for intel ?
Also, are you sure BusID is correct for the card ? |

If I understood correctly I need to use modesetting in order to be able to utilize the concept of using the intel card as "sink" for the nvidia card. I took the xorg.conf I wrote directly from this site: http://us.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html
Also I am pretty sure the BusID is correct unless I made a spelling mistake in the xorg.conf I am not aware about right now (I can't review the files right now as I am at work now and paste.ru is blocked here)
I also think the intel driver is installed correctly as I am able to use the x-server without problems when I delete the xorg.conf. But if I do that, the x-server will only use the intel card. |

Hi,
I have laptop with optimus. all working well. I end with this configuration is needed:
I have also a switch script witch does switch the nvidia - intel GPU for powersave - PM if you want it.
This is my xorg.conf
| Code: |
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"
Option "IgnoreEDID" "1"
#Option "AllowEmptyInitialConfiguration"
EndSection
Section "Device"
Identifier "intel"
Driver "modesetting"
BusID "PCI:0:2:0"
EndSection
Section "Screen"
Identifier "intel"
Device "intel"
EndSection
|
and my /usr/share/config/kdm/Xsetup
| Code: |
#! /bin/sh
# Xsetup - run as root before the login dialog appears
if [[ "$( head -1 /root/nvidia)" == "1" ]]; then
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
fi
|
Hope it helps. |

Hello,
I have tried the proposed solutions but those weren't successful. The problem still persists with the same error message. I think the problem lies within x.org and not the driver.
Solutions tried:
- xorg.conf from phnx12 (I put the xrandr commands in the xinit file but the effect should be the same - anyway, since I can't start the x-server I can't use xrandr anyway)
- exchanging modesetting driver for intel driver
- rechecking the BusID and adding the BusID for the Intel card.
Any other ideas maybe? |
