Hi, all. Like the subject says, are there any known issues with Nvidia that might have cropped up in the last few days with Fedora 42?
I’ve been using a custom build of aurora-dx-nvidia:latest (i.e. Fedora 42) since last week. The build is done with Blue Build and only adds a few packages (Bitwarden, NordVPN, Emacs), so nothing fancy. I just updated my main laptop from a base of latest-42.20250415.1 to latest-42.20250420, and now my external monitor is seen as “Nvidia DP-2-0x0000” with only one resolution (640x480!). Until rebooting (and the week or so before that when it was on aurora-dx-nvidia:stable) it was seen correctly as a Dell monitor with its correct resolution options. I’ve tried a few things like plugging it into a different port (USB-C) and even rebooting again with no change.
Any tips on how to troubleshoot this? I’m not sure what to even look for in the logs.
Update: I just rebooted into my previous latest-42.20250415.1 build and I’m still having the same issue, so that’s really strange. I haven’t even used this laptop in the last few days, but last week I was doing some dev work and some gaming and everything was working great.
Any tips on how I might debug this, or how I might get back to a working configuration? Since the older build is having the same problem, it must be related to configuration somehow. Though I haven’t changed anything at all myself, so I’m not even sure what could have caused this.
Some messages in dmesg made me wonder about the monitor cable, and after reseating it at the monitor end it came back fine. It was already connected tightly, and hasn’t been changed or moved in maybe a year, so who knows.
That’s way better than an unknown lol, glad you got it sorted out. You’ll likely want to move to the open driver with your hardware but there’s plenty of time to do that later and in a non-stressful situation, heh.
I did see some quick web searches earlier and saw some Reddit conversations related to the open driver. Some people seemed to think the open driver was better in some ways, and others thought it was still too buggy. The discussions I saw were from 1-2 years ago, so presumably the open driver is a lot better now.
Is there a general consensus these days that the open driver is better (for reasons?) and as stable as the non-open driver?
Gamer’s Nexus has done some research on it,
If you’re interested in game compatibility.
I’d like to know if there is any effect on CUDA. Nvidia is recommending the open driver for their high end data center cards, so The issues reported to, and tested by, Gamer’s Nexus might be isolated to game play/content creation, rather than crunching numbers (AI/ML). I don’t know.
