https://bugs.freedesktop.org/show_bug.cgi?id=91333 --- Comment #16 from Mark Cave-Ayland mark.cave-ayl...@ilande.co.uk --- Ben - thanks for the patch! I managed to find a few minutes to test the patch at comment #11 today and unfortunately it didn't fix the issue for me. I'll post the updated information back over at bug #56615 so it's all in one place. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

Completely untested patch attached. Ok, I will see if I can build the code with this patch. Thanks :) Well, I was able to apply the patch to the kernel and build it, but after I installed the new kernel, and rebooted, I wasn't able to get past the luks disk decryption. So I don't know what I did wrong, but in any case that kernel will not boot. I'm sure it's not related to the patch; it's that I don't know how to correctly build the kernel. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

Tonight I will see if I can use just the integrated video (i915, I guess) for both external displays. I tried using just the integrated driver, and it seems to only know about the LVDS display.

https://bugs.freedesktop.org/show_bug.cgi?id=91333 --- Comment #8 from Mark Cave-Ayland mark.cave-ayl...@ilande.co.uk --- Apologies for jumping in on another bug report, however this sounds exactly like the problem I've been struggling with for years on my Lenovo T420s: https://bugs.freedesktop.org/show_bug.cgi?id=56615 I see the same symptoms in that the kernel hangs with an external DisplayPort connected in discrete mode when trying to use the internal LVDS with the external monitor. It seems the message I get in the kernel log is similar too: nouveau E[ PDISP][:01:00.0] chid 1 mthd 0x0080 data 0x 0x5080 0x000 -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=91333 --- Comment #10 from Ilia Mirkin imir...@alum.mit.edu --- A few people who have had these PDISP errors were due to gnome toggling cursor state when a CRTC had not been enabled, and nouveau not properly protecting against it. There was a (lost) patch that fixed it, unfortunately I don't remember where the place was. Ben should be able to come up with that patch fairly easily. However for the user in question, while the PDISP error dumps went away, the underlying problems remained. Just a thought. [As an aside, Corey, with reverse-prime you should also be able to get all 3 screens up... see http://nouveau.freedesktop.org/wiki/Optimus/ . Of course nothing is perfect, this also introduces tons of problem for some people. But not others.] -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=91333 --- Comment #2 from Ilia Mirkin imir...@alum.mit.edu --- While going crazy is rarely the right thing to do, I'd like to point out that a GF108 only has 2 CRTC's and thus can only ever power 2 different screens at a time. (There might be a way to drive 2 identical screens at once from a single CRTC, not sure.) I suspect a negative interactions with gnome which might get confused about such a restriction. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

(There might be a way to drive 2 identical screens at once from a single CRTC, not sure.) Yeah, I realize that. Just as a reference point, two external monitors works fine with Windows 7, even with just the Nvidia chip enabled (discrete graphics). With Optimus enabled, I can actually drive all three monitors simultaneously. I suspect a negative interactions with gnome which might get confused about such a restriction. Maybe so.

https://bugs.freedesktop.org/show_bug.cgi?id=91333 --- Comment #5 from Corey Ashford cjash...@us.ibm.com --- (In reply to Ilia Mirkin from comment #4) I bet it works if you first disable one of the screens before plugging a third one in. I had tried that experiment before, but I just now tried it again. Same bad result. Here are the steps I took. 1) Boot laptop with no external monitors connected. 2) Attach Displayport-connected monitor. All is well. 3) Disable internal monitor. All is still well... now using only the external monitor. 4) Plug in VGA monitor. 5) Nothing happens. 6) I bring up the Gnome Displays setting (not clicking anything yet), then the system starts with its display resetting (or whatever it's doing), and becomes unresponsive to keyboard input. 7) The only way to get back to a usable system is to disconnect the VGA display, which after 5-10 seconds gets me back to the Gnome login, and after logging in I was able to capture the dmesg output (will attach). -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
