Yes, there is a USB-C "port extender" (dock) attached to this Lenovo laptop. The model is the MUC-0501B. It is this exact device : https://amzn.to/3XA5u5N -- "USB C Adapters for MacBook Pro/Air,Mac Dongle with 3 USB Port,USB C to HDMI, USB C to RJ45 Ethernet,MOKiN 9 in 1 USB C to HDMI Adapter,100W Pd Charging, USB C to SD/TF Card Reader USB C Hub".
I also have noticed occassional flickering. What's interesting is that either the display controlled via this, or via the direct HDMI port will "drop out" for a second or 2 when the mouse moves between the screens. If I move the mouse back to the alternate screen, the display comes back. ** Attachment added: "video of a related(?) problem." https://bugs.launchpad.net/linux/+bug/2003031/+attachment/5642054/+files/PXL_20230117_204102229.mp4 -- 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/2003031 Title: gnome-shell crashes in the kernel at drm_atomic_check_only and the kernel says "adding CRTC not allowed without modesets: requested 0x4, affected 0x7" To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/2003031/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
