I’m having a blank screen issue on Ubuntu 21.10 with a GTX 1650.
I’ve tried the nvidia-driver-470 and nvidia-driver-495 packages, both from the distro and the graphics-drivers PPA.
This setup worked previously with an earlier version of nvidia-driver-470 or possibly 460, but I can’t remember the exact version that worked. I’m currently on version 495.46.
If I connect the display to the DisplayPort output via a KVM, I get a blank screen at startup. If I connect the display directly without the KVM, it works.
However, I don’t think the KVM is the issue, because it works using the nouveau driver with the KVM, and I’ve tested the KVM with nvidia cards on other computers.
This is the bug report with the display connected via KVM: nvidia-bug-report.log.gz (295.1 KB)
This is the bug report without the KVM (i.e. the working setup): nokvm_nvidia-bug-report.log.gz (280.1 KB)
I’ve tried changing the
nvidia-drm.modeset parameter in
/etc/default/grub and it didn’t help. I’m not sure if I should be blacklisting nouveau or not.
Thanks for reading, I’d appreciate any suggestions.
