Public bug reported:
I have a laptop computer with hybrid graphics : 'Intel Onboard IGD' and
'Nvidia GeForce GTX 1050 Ti Mobile'.
The 'Intel Onboard IGD' correctly manages the onboard monitor with
resolution 1920 x 1080.
But I need the Nvidia card to manage an external monitor with resolution
4K2K connected to DisplayPort.
At the beginning, the 'nouveau' module of the Linux kernel seems to be
correctly loaded :
$ lsmod | grep '^nouveau'
nouveau 1601536 0
But XORG does NOT load its 'nouveau' module. So, I force it with following
file :
$ cat /usr/share/X11/xorg.conf.d/20-module-nouveau.conf
Section "Module"
Load "nouveau"
EndSection
In the attached 'Xorg-with-nouveau.0.log' file, you can see :
- Lines 58-59 : XORG correctly finds both Intel and Nvidia graphics
hardware.
- Lines 61-66 : XORG loads its 'nouveau' module.
- Lines 94-108 : The list of the Nvidia chipsets known by the
'nouveau' module does NOT contain 'GTX 1050'. Is this meaningful ?
- Line 123 : Message ending with 'cannot open kernel arbiter, no
multi-card support'.
Is this meaningful ? If yes, is it possible to activate
the 'kernel arbiter' ?
- Lines 124-226 : The 'modesetting' module of XORG (perhaps with the
help of the 'glamoregl' submodule) correctly reports the 4 available
graphics outputs, in particular 'eDP-1' connected to the onboard
monitor.
- Lines 233-234 : XORG unloads its 'nouveau' module, which has NOT
reported any graphics hardware or outputs
If necessary, I am able to test :
- the latest version of the 'xserver-xorg-video-nouveau' package from a PPA
- the latest upstream kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline
Finally, I wonder where this issue has to be solved :
- inside configuration files in '/usr/share/X11/xorg.conf.d',
- inside the 'xserver-xorg-video-nouveau' package,
- inside the 'nouveau' module of the Linux kernel,
- inside the 'kernel arbiter'.
Thank you in advance for your help.
