really appreciate it @tinko
Hi there,
Thank you for providing the detailed information about your system. I am running a similar setup with V23 RC2 and dual monitor, though I only have one graphics card - Nvidia and the multi-monitor works OK for me, so I trust we'll be able to resolve this, so please bear with.
Could you please provide the following additional information?
Current Xorg Configuration: Please share the contents of your /etc/X11/xorg.conf file, if it exists. You can do this by running the following command in the terminal and copying the output:
中文 
cat /etc/X11/xorg.conf
Check NVIDIA Configuration: Open the NVIDIA X Server Settings by typing nvidia-settings in the terminal and check if both monitors are detected. A screenshot of this window would be helpful.
Logs for Errors: Check and provide any recent errors from the Xorg log by running:
cat /var/log/Xorg.0.log | grep '(EE)'
System Information: Additionally, please provide the output of the following command to get more details about your system's graphics setup:
inxi -G
Once I have this, I can look at provide more targeted advice to resolve the issue.
Thank you for your cooperation and patience.
Best regards,
deepin Hi Tinko,
Thank you for your response and for sharing your experience with a similar setup. It's reassuring to know that the dual monitor setup works for you with just the Nvidia card. I'm hopeful that we can resolve this issue together.

Hi and huge apologies for the radio silence.
Thank you for providing the additional information. Based on the details you've shared, there are a few steps that can help resolve the multi-monitor issue:
Please note that these steps involve modifying system configurations, which could affect system boot. Since this is a Release Candidate (RC) version, it is not recommended for use on a production machine.
Ensure you have backups or you are okay to reinstall in case of boot issues.
Now let's try and fix this.
Xorg.conf
Since there is no xorg.conf file, let's create one to explicitly configure both GPUs and set up PRIME correctly. Open a terminal and run:
sudo nano /etc/X11/xorg.conf
Add the following configuration and save the file:
ection "ServerLayout"
Identifier "layout"
Screen 0 "nvidia"
Screen 1 "amd" RightOf "nvidia"
EndSection
Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "AllowEmptyInitialConfiguration"
EndSection
Section "Device"
Identifier "amd"
Driver "amdgpu"
BusID "PCI:5:0:0"
EndSection
Section "Screen"
Identifier "nvidia"
Device "nvidia"
EndSection
Section "Screen"
Identifier "amd"
Device "amd"
EndSection
PRIME Configuration
Ensure PRIME is correctly configured for using the NVIDIA GPU. Run the following command to set NVIDIA as the primary GPU:
sudo prime-select nvidia
sudo reboot
GRUB Configuration
Add the nvidia-drm.modeset=1 parameter to ensure NVIDIA DRM modeset is enabled. Open a terminal and run:
sudo nano /etc/default/grub
Modify the GRUB_CMDLINE_LINUX_DEFAULT line to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1"
Save the file and update GRUB:
sudo update-grub
sudo reboot
NVIDIA Settings
After rebooting, open the NVIDIA X Server Settings by typing the following command in the terminal:
nvidia-settings
Check if both monitors are detected. If the issue persists, please provide a screenshot of this window.
Thank you for your patience.
Best,
Tinko

I found out that while using live cd test Deeping, multi monitor is working in any mode (Duplicate, extend). However after setup the Deepin the multi monitor is not working.
