 Posted: Wed Nov 13, 2024 2:47 pm Post subject: No video output from secondary Nvidia RTX 2050 card |
 |
|
I have installed gentoo on an Acer aspire laptop, which has a builtin Intel video card
| Code: | | 0000:00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P GT2 [Iris Xe Graphics] (rev 0c) |
and Nvidia video card
| Code: | | 0000:01:00.0 3D controller: NVIDIA Corporation GA107M [GeForce RTX 2050] (rev a1) |
with kernel 6.6.58-gentoo and nvidia drivers 550.127.05-r1 (other version do not work either).
The laptop has no BIOS option to switch the video cards.
Nouveau drivers do not support this nvidia card.
Relevant kernel parameters:

When X is started without xorg.conf, or with xorg.conf selecting the builtin intel card,
video works:
| Code: | Section "Device"
Identifier "intel"
# Driver "modesetting"
# Option "AccelMethod" "none"
# Option "UseEdidDpi" "FALSE"
# Option "DPI" "100 x 100"
BusID "PCI:0:2:0"
EndSection
#Section "Device"
# Identifier "nvidia"
# Driver "nvidia"
# VendorName "NVIDIA Corporation"
# BusID "PCI:1:0:0"
# Option "AllowEmptyInitialConfiguration"
#EndSection
Section "Screen"
Identifier "intel"
Device "intel"
Monitor "Monitor0"

However, I would prefer to use the more powerful Nvidia video card. When that is selected in the xorg.conf (uncommenting the above and selection Device "nvidia" in Section Screen,
the X server runs, without reporting an error, but I get a black screen (and no signal on HDMI).
Additionally, when running through the intel card, and trying to run selectively something
on nvidia e.g. 'prime-run glxgears' that runs but the window is black-empty.
If I disable all I915 options in the kernel, X also runs without errors, but with a black screen.
So I suspect that somehow the output of the Nvidia card does not pass through whatever
internal switch to get to the screen and have no idea how to solve this. Any help?
Steps to Reproduce:
1. configure xorg.conf to use nvidia card
2.start X server
3.
Actual Results:
running X server, but black screen and no HDMI signal
Expected Results:
video output on the screen from the running X server and Nvidia card
