[Bug 2027631] Re: [ASUS EXPERTBOOK B9400CBA] No signal to external monitor from HDMI port
The kernel is only seeing the built-in display as "connected": /sys/class/drm/card0-DP-1/status:disconnected /sys/class/drm/card0-DP-2/status:disconnected /sys/class/drm/card0-eDP-1/status:connected If we assume one of those DP ports is actually the HDMI port then the problem would be a connector or cable issue. If however those DP ports are the USB-C ports then the HDMI port seems to be missing at the kernel level :( If the laptop has two GPUs then the second one would own the HDMI port, but I don't see a second GPU here. Unless it exists and is disabled in the BIOS? ** Package changed: mutter (Ubuntu) => linux-hwe-5.19 (Ubuntu) ** Changed in: linux-hwe-5.19 (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2027631 Title: [ASUS EXPERTBOOK B9400CBA] No signal to external monitor from HDMI port To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.19/+bug/2027631/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Daniel above are the txt files you've requested. Have tried 6.2 6.4 kernels in my previous installation with no success. That's when decided to reinstall and report the bug on clean system with supported kernel. Have also tried reinstalling gpu drivers with this guide no success, either https://dgpu-docs.intel.com/installation-guides/ubuntu/ubuntu-jammy-arc.html -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2027631 Title: [ASUS EXPERTBOOK B9400CBA] No signal to external monitor from HDMI port To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2027631/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
