I'm sorry for spamming this bug report, I should've make all my tests before posting anything.
I made a clean install today but, this time, without installing the proprietary drivers during setup. I installed the Nvidia driver after the first batch of updates, via the Additional Drivers application. And I can't reproduce this issue anymore. It's working as it should. It unfortunately means that installing the proprietary drivers during setup isn't working well. For instance, I had to manually install the nvidia-dkms-440 package, which was missing. I can't say for sure that this bug is also caused by a faulty Nvidia driver installation, but it looks like it. If someone can tell me where I can report this issue, I'll gladly make it (if it hasn't been reported yet). Once again, sorry for spamming this bug report. Feel free to delete some of my comments, as I don't feel they're really useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877727 Title: Nvidia dGPU active despite prime-select set to Intel card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1877727/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
