[SOLVED] openSUSE 15 and dual GFX

Hungry ghost · 01-18-2019, 07:54 AM

Hi guys,

I recently upgraded to openSUSE 15 (fresh install) on my RV510V laptop. It has dual graphics cards (Intel and Nvidia); however, the laptop is using the Intel card with a low resolution (1024x768) and I would prefer it would use the Nvidia card.

These are the relevant entries after running lspci -k:

Code:

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
        Subsystem: ASUSTeK Computer Inc. Device 1130
        Kernel modules: i915

01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 950M] (rev a2)
        Subsystem: ASUSTeK Computer Inc. Device 1130
        Kernel driver in use: nvidia
        Kernel modules: nouveau, nvidia_drm, nvidia

I installed the "x11-video-nvidiaG05" package from the Nvidia repository (https://download.nvidia.com/opensuse/leap/15.0). However, when I run nvidia-xconfig and restart the system, I can't get into graphics mode and have to delete xorg.conf in order to use the Intel card and graphics mode again (with low resolution). It's the same if I use the "x11-video-nvidiaG04" driver.

By the way, I already specified "nomodeset" on Grub and ran grub2-mkconfig -o /boot/grub2/grub.cfg.

Does anyone has a clue about how to solve this issue?

Thanks for your help!

Not from a hands-on approach, since I have no laptops and thus no Optimus hardware, but this subject does come up a lot in the openSUSE forums, where the routine includes pointing to the following URLs:
https://en.opensuse.org/SDB:NVIDIA_Bumblebee
https://en.opensuse.org/SDB:NVIDIA_SUSE_Prime
https://wiki.archlinux.org/index.php/NVIDIA_Optimus

First thing to note is that by default openSUSE installs Plymouth, which is usually incompatible with the proprietary NVidia drivers. Thus removing Plymouth is a good choice of first move when resolution is low, or screen is black, or both.

Also note that all competent FOSS X drivers are incapacitated by the presence of nomodeset on kernel cmdline. This may or may not apply to recent NVidia driver versions, which, at least in the past, depended on its presence. The incapacitation typically causes fallback to FBDEV or VESA drivers, which usually present 1024x768 mode or worse, unless NVidia is fully and correctly installed.

Hi mrmazda, thank you for your answer and sorry for the late reply. I've been quite busy lately. I will give it a try when I have some time and post back my results.

Cheers!

Well, I finally ended up installing Linux Mint 19 and fixed the dual graphics card issue installing the Nvidia driver and nvidia-prime, besides editing /etc/default/grub following the instructions in this link.

Thanks for your help!
