Hello,
I am experiencing an issue with my HDMI connection through a docking station on my Arch Linux system running on an ASUS TUF Dash F15 with a dual GPU setup (NVIDIA GeForce RTX 3060 Mobile / Intel Alder Lake-P GT1). The connection works fine initially;
however, after the computer wakes up from sleep, one of the HDMI displays (connected via the docking station) is not recognized. Replugging the docking station seems to resolve the issue temporarily.
System Information:
OS: Arch Linux x86_64
Host: ASUS TUF Dash F15
Kernel: 6.1.53-1-lts
DE: GNOME 44.5
GPU: NVIDIA GeForce RTX 3060 Mobile / Intel Alder Lake-P GT1
Output of xrandr when it works:
""
Screen 0: minimum 320 x 200, current 4920 x 1920, maximum 16384 x 16384
eDP-1 connected primary 1920x1080+1080+373...
DP-1-0 connected 1920x1080+3000+373...
HDMI-1-0 connected 1080x1920+0+0 right...
""
(Note: After wake up, the "DP-1-0" is listed as disconnected.)
Output of lsusb:
""
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Output of dmesg | grep -i display:
""
[ 0.245204] ACPI: USB4 _OSC: OS supports USB3+ DisplayPort+ PCIe+ XDomain+
[ 0.245204] ACPI: USB4 _OSC: OS controls USB3+ DisplayPort+ PCIe+ XDomain+

All other ports in the docking station continue to work as expected (e.g., speakers and mouse). The two external monitors I am using are of the same model from Samsung.
What I have tried:
Unbinding and rebinding all the USB ports to refresh them, without success.
Updating the system and drivers using pacman -Syu.
I am need guidance or suggestions to resolve this issue. Has anyone encountered a similar problem or have insights on potential fixes?
Thank you in advance for your assistance!
