Created attachment 97517 [details] nouveau debug log with PDISP=debug,DEVINIT=debug Good time of day. I have MacBook with ArchLinux installed. When resuming after suspend, there is minor screen corruption. It looks loke small dashed line, approximately half of screen height, fading to transparent at both sides. It is oriented vertically, moves from top of the screen to the bottom, then appears again. I'm attaching here Xorg log and nouveau.debug dmesg log with normal boot -> suspend -> wake. My versions of packages: local/xorg-server 1.15.1-1 (xorg) local/xf86-video-nouveau 1.0.10-2 (xorg-drivers xorg) local/mesa 10.1.0-5 local/linux 3.14.1-1 (base) I also can bring any information you need. Really want to help.

Why do you disable PCE0 ? (You seem to have a nouveau.config=PCE0=0 somewhere.) Are there other options set? Is the resume issue a new one? (i.e. did it work OK with older kernels?)

With kernel 3.10 it was worse - dashed line persisted even on clean boot (without suspend -> wake).

I checked the code... there's a bool enable = (nv_device(parent)->chipset != 0xaf); So that's probably the reason why it's disabled. No idea why that's the case on NVAF, but I'm guessing that the person who put that in knew what they were doing. It also shouldn't cause problems for it to be disabled, I was just curious why it was. > > > Are there other options set? > > Where can I look at the list? /etc/modprobe.d/ is empty now > > > Is the resume issue a new one?

Sorry, no great advice from me :(
Don't worry about it. Just wanted to help you a little. All the other video issues were fixed, so I finally can feel comfortable. I really appreciate your work. Thanks for answer!
