Hi: For (1): The NVIDIA GPU cannot be disabled in the BIOS, only switched to the "hybrid" mode. The outputs are shown as attached to the GPU with these commands: $ cat '/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/vendor' 0x10de $ ls '/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0' card0-DP-1 card0-DP-2 card0-DP-3 card0-eDP-1 card0-HDMI-A-1 dev device power subsystem uevent
As you can see, the vendor of this PCI device is NVIDIA and the outputs are attached directly to it. For (2), I have tried with 4.19 on Debian 10 and it produced the same issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876534 Title: ThinkPad P72 - Very serious issues with external monitors on Thunderbolt dock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1876534/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
