[Bug 1207776] New: External monitor ceased working in the middle of an X11 session and cannot be reactivated
http://bugzilla.opensuse.org/show_bug.cgi?id=1207776 Bug ID: 1207776 Summary: External monitor ceased working in the middle of an X11 session and cannot be reactivated Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: screening-team-bugs@suse.de Reporter: rainer.klute@gmx.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have been using an external monitor on my notebook (Lenovo Thinkpad P50) under openSUSE Tumbleweed) for years. However, this has now come to an abrupt end. In the middle of an X11 session, at the same moment I started a (third) VLC instance, the external monitor went dark and all windows of my X11 session were moved to the internal notebook screen. The external monitor was, and still is, not recognized by the machine, not even after a reboot. This does not only happen on the X11 level, but already further down on a lower level. The ���inxi��� command only shows the internal monitor, no longer the external one. Udev correctly creates all the devices for all the display ports of the notebook, but when I connect the external monitor to the HDMI-1 port, the kernel does not create a uevent. Consequently, no udev event is issued, both according to ���udevadm monitor���. Here are the devices and their states: /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-1/status: disconnected /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-2/status: disconnected /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-1/status: disconnected /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-2/status: disconnected /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/status: connected Yet, in an X11 session, the notebook somehow recognizes that a monitor is connected: An OSD screen is displayed asking how to configure the new monitor. Clicking on any of the alternatives has no effect, however. I am ruling out any hardware error. Why? Because the external monitor works fine on a second notebook. And when I boot a Linux live system on my first notebook, the external monitor is recognized and used without any problems. On the other hand, if I use my notebook with the actual operating system with a different external monitor, it doesn���t work either. I test booted the older kernel version 6.1.1 instead of the (as of this writing) current 6.1.8 kernel. I also tried an older version of the i915 driver. Both measures showed no effect. Now I ran out of ideas what else to try or where else to look. And as far as I am aware of, the status of connected hardware isn���t stored anywhere where it survives a reboot ��� or is it? -- You are receiving this mail because: You are on the CC list for the bug.

When the system is booted up, attach the external monitor and then capture the dmesg output and upload it here. That way we can see in detail what is happening when you attach the external monitor. -- You are receiving this mail because: You are on the CC list for the bug.

I would suspect the external connector is attached to the nvidia gpu. And it seems you have the "open" nvidia driver installed which doesn't support your gpu: [ 14.121892] nvidia 0000:01:00.0: enabling device (0006 -> 0007) [ 14.126777] nvidia 0000:01:00.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=none:owns=none [ 14.126802] NVRM: The NVIDIA GPU 0000:01:00.0 (PCI ID: 10de:13b0) NVRM: installed in this system is not supported by open NVRM: nvidia.ko because it does not include the required GPU NVRM: System Processor (GSP). NVRM: Please see the 'Open Linux Kernel Modules' and 'GSP NVRM: Firmware' sections in the driver README, available on NVRM: the Linux graphics driver download page at NVRM: www.nvidia.com. [ 14.126870] nvidia: probe of 0000:01:00.0 failed with error -1 [ 14.126906] NVRM: The NVIDIA probe routine failed for 1 device(s). [ 14.126909] NVRM: None of the NVIDIA devices were initialized. Adding Stefan to CC. Stefan, should this card be supported by the new nvidia driver? -- You are receiving this mail because: You are on the CC list for the bug.
