> Again, the issue is present using Nouveau too in 6.5.
I assume you mean the main bug here and not those log messages because
'nvidia-drm' is the proprietary driver meaning Nouveau shouldn't be
loaded.
** Summary changed:
- [mantic] New 6.5.0.2 kernel + Intel GPU = no HDMI
+ No HDMI in Nvidia
Using 6.5 (hybrid graphics "on-demand" mode), I get these errors in logs:
[drm:nv_drm_load [nvidia_drm]] ERROR [nvidia-drm] [GPU ID 0x0100] Failed to
allocate NvKmsKapiDevice
[drm:nv_drm_probe_devices [nvidia_drm]] ERROR [nvidia-drm] [GPU ID 0x0100]
Failed to register device
I do not
HDMI works with 6.3.13.

Ok, in 6.3.13 with nvidia-535 *I get* this "launch with dedicated gpu"
app menu item and both intel + nvidia gpu are listed in g-c-c system
details. So I suppose hdmi is working (I did not test this).
So there's a kernel-related issue.

Oh mainline kernels probably don't support the Nvidia driver. Or perhaps
just don't have the nvidia kernel driver built for them. So your GPU
missing is expected in that case. I was hoping you still had the
official Ubuntu kernel 6.3 installed from before the upgrade to 6.5
where nvidia was still
Any kernel 6.3 will do, so long as you're still using libmutter >= 45.0

Ok I tested 6.3.13 from Ubuntu mainline ppa.
There's no "launch with dedicated gpu" app menu option, Nvidia is not listed in
g-c-c system details.
So there's another point. That's why I reported another bug against GNOME Shell.
Please remind that my nvidia gpu is listed by lspci:
01:00.0 VGA
"on-demand" is the Nvidia Prime profile, it is dynamic graphics, Intel GPU is
used but I can launch any app with Nvidia GPU through GNOME app's menu.
I can select dynamic graphics or discrete graphics in BIOS.
Please note that there *is* a bug since I cannot launch an app using
nvidia, when
Also are you sure it's a kernel issue and 6.3 *still* works?
I fixed a bug in mutter this week that would have previously kept the
discrete GPU awake even when it wasn't being used. That was a bug
though.

I don't agree:
1) this was working using kernel 6.3 (or maybe another software cause?)
2) this is working using Windows 11 that I have use too on my laptop
So I cannot see why no-hdmi is the right behaviour.

I don't think this is a bug. When the Nvidia GPU is disabled it is
expected that the ports wired to it will also be disabled.

Forgot to mention: in Windows 11, on-demand is working with hdmi
monitors.

Same issue using 6.6 from Unstable PPA.
Using intel session in current 6.5 kernel (on-demand mode in Nvidia params),
the Nvidia GPU is simply not detected. I cannot launch an app using Nvidia gpu
in GNOME app menu.
And maybe some ports like hdmi are linked to the Nvidia GPU.
Using Intel
Additionally, without any monitor connected:
- using dynamic graphics and Nouveau and 6.5.0-6 kernel does not boot (hang
after disk pwd prompt was ok)
- using dynamic graphics and Nouveau and 6.5.0-5 kernel does boot but GNOME
does not offer me to start an app using dGPU (and GNOME settings
At the moment, with latest 6.5 Ubuntu kernel:
- dynamic graphics: hdmi or usb-c (then hdmi and dp) monitors are not detected,
whatever I use Nouveau or Nvidia 535
- discrete graphics: all is ok, Nouveau or Nvidia
In GNOME settings/display, when I use dynamic graphics (Intel here), I
don't see
I'm confused by this report. What exactly is working as expected and
what is not?

Tested with Nouveau, so no Nvidia 535 driver.
HDMI screen is not even detected. Same behavior using an USB-c dock (hdmi + dp

Hi,
Legion laptop with Nvidia.
- Nouveau : no hdmi
- Nvidia 535 dynamic graphics : no HDMI (screen not detected)
- Nvidia 535 discrete graphics : HDMI is detected
So I suppose
