[nvidia][Xorg] One (cloned) monitor remains black on startup or resume from sleep

[Lsdp]

when the pc starts up or comes out of sleep mode the primary screen remains black. To reactivate it I have to go through screen clone apply and redo join the screens and apply.

Thanks

Ps: have done several research and attempt, without success, on the internet including in your forums.

Is it the IBM or the LG monitor that remains black?

I can't see any hints of a problem in the log. It sounds like maybe GNOME can't uniquely identify one of the monitors and so can't remember its preferred setting.

[Daniel van Vugt (vanvugt)]

Maybe try enabling Wayland and then see if logging into 'Ubuntu on Wayland' avoids the problem.

To enable Wayland you will need to change the kernel parameter:

  nomodeset

to:

  nvidia-drm.modeset=1

and then run:

  sudo update-grub

and reboot.

Thank you very much for your help.
It is the LG on Displayport or Hdmi that stays black. I have noticed
that when in a dual monitor there is a VGA port connected it is always
the VGA port that is recognized in both Linux and Window; I think that
this is the characteristic of the X86 architecture.
I will try to install Wayland.
Thanks

RESOLVED
Hello
I applied your recommendation by placing nvidia-drm.modeset=1 in
etc/default/grub
and confirmed with
cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.13.0-35-generic
root=UUID=c8e08c76-0308-495c-8c5a-83f9aa24b1a0 ro nvidia-drm.modeset=1
I replaced the Nvidia 470 driver with the override 510 driver.
Also, I did put the video card from PCIE 2 to PCIE 1.
Everything works perfectly in X mode and this after a standby or a reboot.
DP monitor 1 and VGA monitor 2

I tried the Wayland and had several bugs; general crash or severe screen
corruption.

Thanks a lot for your help
PS if you have ideas for the Wayland mode I'm willing to try.
