Apparently this is an “Optimus” laptop. Is switcheroo-control installed?

zypper se -si switcheroo-control

and if so, what does switcherooctl list display?

23

It shows this:

Device: 0
  Name:        IntelÂŽ UHD Graphics 630
  Default:     yes
  Environment: DRI_PRIME=pci-0000_00_02_0

No NVIDIA. Ideas?

Your *ERROR* [nvidia-drm] Failed to allocate NvKmsKapiDevice indicates a resource conflict during the handover from the boot-framebuffer to the NVIDIA driver. Even though openSUSE typically sets modeset=1 in /usr/lib/modprobe.d/50-nvidia.conf, adding it explicitly to GRUB ensures it’s active from the very first second of the boot process.

1. Disable SimpleDRM / EFI Framebuffer Conflicts Modern kernels use simpledrm to show a boot logo, which often blocks the NVIDIA driver from ‘grabbing’ the display resources. You should try to combine the NVIDIA modeset parameter with flags that disable the conflicting framebuffer. Add these to your GRUB kernel parameters:

nvidia-drm.modeset=1 video=simplefb:off initcall_blacklist=simpledrm_init

(Alternatively, try sysfb.modeset=0 if the above doesn’t work.)

2. Check for Hybrid Graphics Conflicts In your log, I see i915 (Intel) taking over fb0 very early. On some Legion Y740 models, the ACPI refuses to hand over the KMS (Kernel Mode Setting) capability to NVIDIA if the system is in Hybrid mode.

  • Test: If your BIOS allows it, switch from ‘Hybrid Graphics’ to ‘Discrete Graphics’ only and see if the driver loads successfully.

3. ACPI Backlight Handling Sometimes the way the kernel handles display connectors on Legions interferes with the DRM allocation. You could also try: acpi_backlight=vendor

The NvKmsKapiDevice failure basically means the NVIDIA DRM layer couldn’t initialize because the hardware resources were already ‘locked’ by the generic system framebuffer."

25

Apologies, where do I add acpi_backlight=vendor? Sorry again where is Grub located in Opensuse Leap 16? I only see Grub2 and it does not contain entries when I used VIM to edit it. Further, will I do sudo update-bootloader afterwards and reboot?

As to BIOS, I tried to switch to Discrete Graphics but the screen becomes unusable due to white lines and flickering so I went back to “switchable graphics” settings.

Thank you and so sorry for being a hassle and asking for steps on how to update Grub. Thank you.

26

@donmarcos Is this correct:

GRUB_CMDLINE_LINUX_DEFAULT="mitigations=auto quiet security=selinux selinux=1 rd.driver.blacklist=nouveau ia32_emulation=1 nvidia-drm.modeset=1 video=simplefb:off initcall_blacklist=simpledrm_init acpi_backlight=vendor"

I edited Grub via vim /etc/boot/grub. If the above is correct, what do I do after? Do I run sudo update-bootloader and reboot? Thank you.

27

Try the setting first before changing grub.cfg:

In the boot menu hit ‘e’ and look for the line beginning with linux /boot/vmlinuz...
At the end of this line add acpi_backlight=vendor (or the other suggested settings). Then hit F10 to continue booting.

If you find a working configuration, then you can edit the grub2 boot setings. I suggest using “YaST Boot Loader” found in the System Menu, there you’ll find the tab Kernel Parameters

28

I tried all the above suggestions including sysfb.modeset=0 and it does not solve the issue - sadly. Here is my current inxi -GSaz:

Do I reinstall NVIDIA? or format the laptop and do it again? Thanks.

29

YaST is deprecated and the main application got removed from Leap 16. Only single modules can be installed (not the default).

To add or remove kernel command line parameters, nowadays update-bootloader is used.

To add a parameter permanently:

sudo update-bootloader --add-option xxxxxxxx
sudo update-bootloader

To remove a parameter permanently:

sudo update-bootloader --add-option xxxxxxxx
sudo update-bootloader

For more information, see man update-bootloader.

30

Apparently the nvidia driver is loading, so reinstalling is not the first option. There is something preventing the system to access the interface. Gaming laptops like yours may have highly customized BIOSes, especially in the graphics area.
Maybe the Nvidia chip is disabled, powered down, suspended or whatever: check all related settings (anything else beyond “Switchable graphics” and “Discrete”?) or power save and related settings (there might be something powering down the Nvidia to save battery life?), then use mains power, not battery (just in case…)

31 
sudo update-bootloader --del-option xxxxx

And just to rule out the obvious, please post:

sudo lspci -nnk |grep -EA3 "VGA|3D|Display"
33

My apologies. On my fresh tumbleweed-Install its still there, so I thought it would be a convenient way to edit boot settings. On Leap its probably gone.

@BLP: Did you look into journalctl -b | grep drm` after changing the boot settings? Is the error still there or other errors? As OrsoBruno mentioned it could be that the GPU is in a powered down state.

34

It’s either a hardware issue or some cruft leftover from previous driver installs. Best way would be to purge all the nvidia rpms, setting and configurations etc and drop back to nouveau to see if that works.

35

@OrsoBruno this is the result:

@malcolmlewis I am open to do this. So, what are the steps? Thank you in advance.

38

Your laptop is no ordinary “Optimus” laptop where the Nvidia is automatically engaged when needed, but there should be something to switch from one to the other GPU.
That is consistent with the “Switchable Graphics” setting in the BIOS.
Normally switcherooctl is used to do such switching, but if it doesn’t list the Nvidia I’m out of ideas.
Apparently the Nvidia works with the “Discrete” setting (even if with artifacts)?
Or is there something else in the BIOS?

39

No, there is nothing in the Bios - I went through it deeply. It is very strange. Do I go install prime-select and remove switcherooctl?

40

No, prime-select is deprecated and I don’t know if it does even work with recent drivers…
Maybe the Nvidia is engaged only when an external display is connected? Anything interesting in the user manual for your laptop?
(Ahhh the usual joy of gaming laptops…)
