Thanks for the bug report. It sounds like the HDMI connection isn't getting the full display info (sometimes). Next time it happens, please run:
journalctl -b0 > journal.txt and attach the resulting text file here. It might be helpful to do the same also when the bug is NOT happening. ** Package changed: ubuntu => nvidia-graphics-drivers-530 (Ubuntu) ** Changed in: nvidia-graphics-drivers-530 (Ubuntu) Status: New => Incomplete ** Tags added: lunar multimonitor nvidia -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-530 in Ubuntu. https://bugs.launchpad.net/bugs/2025585 Title: Nvidia 530 kernel driver monitor resolution problem Status in nvidia-graphics-drivers-530 package in Ubuntu: Incomplete Bug description: I have managed to install the drivers and nvidia-smi shows output but it does NOT detect my external monitor which used to work with previous version of the driver.
