I am running a GTX 970, and any time I try to use kernel 4.7, the screen just goes black.
If I use opensuse with an older kernel, nouveau works fine. If I use fedora with an older kernel, it also works fine. So I know its not a distro problem.
As soon as I use kernel 4.7..............nothing. I have to switch to the cpu graphics to get any video at all.
I would love to use the opensource drivers, but the opensource drivers can't even play youtube videos smoothly. Soooo yeahhhh.
I am thinking about filing a bug report, but I wanted to see if anyone else was running into issues to make sure it is not just my computer acting up.
I made a post about a similar issue. I've seen A LOT of issues with the new kernel and the 970M. I had to install by adding "nomodeset" at the grub menu. After that I got OpenSUSE installed, but had issues getting the graphics drivers working properly.
Oooooooohhh. I get that over DP or HDMI on my a409u, but not on my acer 1080 over DVI. I figured it was some fuckery with nouveau being derpy with the a409u in particular... I even have trouble with the 970 and a409u on Windows.
Guess I didn't read the post well enough.
two things: What's your display setup (resolution, connection type, etc...) and did you ever have proprietary drivers installed?
Its a 25 inch 1440p monitor and I am using display port.
And the answer to your question about the drivers is both yes and no. I have tested both ways to see what would happen.
And let me be clear. I can actually switch back to my CPU graphics and load the 4.7 kernel just fine. Once I get the system up and running, I can install the nvidia driver and then reboot with my gpu graphics and everything works just fine.
I will see if HDMI or DVI makes a difference and get back to you.
If you have a second computer, SSH into your desktop after it's booted into a black screen and run dmesg
If there is anything odd about nouveau, paste it here so I can see if I can help.
See amdgpu has this problem with DP, which may be present in nouveau as well. Basically, it can't pull data for proper clock configuration of displays that are over 1080p, so it errors out and gives up, rather than falling back to 1080. This is all just conjecture at this point though.
For the record, it sounds like it may be a distro issue. Fedora had some issues when they moved to 4.6 as well.
The only thing I have is my moms macbook pro. If I get bored, I suppose I could run something in a virtual machine and then SSH into my PC, but god damn that would be a pain.
You could be onto something because I seem to remember that there were some reclocking improvements made to the 4.7 kernel for nvidia cards.
And I seriously doubt it is a distro problem. Opensuse, fedora, and arch all have the same issue with the 4.7 kernel.
Oh and I just tested DVI and HDMI. Same issue. But nomodeset actually does work.
Grub has been very autistic on Arch Linux with this new kernel as well. I had to reinstall the kernel twice and regenerate the grub config for Grub to recognise the kernel..
I know this is VERY late to the game, but I just re-installed Ubuntu with 4.7 kernel, and I too am having the same issue. Was this solved?
My GTX 970 is a reference card, if that helps. But I was fine on 4.6 I'm assuming that was what I was on. But I reinstalled to the most recent kernel because I had read somewhere that it might help with my NIC card issues I was having with dropping internet connection.
Now, I can only get display through my onboard motherboard video once I restart and take the Nvidia card out.
Nice. Yeah i might take a new close look at open suse or gecko linux aswell again. Last time i didnt had much luck with leap 42 kde. But i think that was more an issue with kde then suse itself.
Leap's software is too old. I really don't like leap TBH. I wish they would go back to their old model or better yet adopt fedoras model.
And if you are going to just play around, I would totally go with geko. If/when you decide to do a full install, I would use the official tumbleweed ISO.
