I'm sorry for posting this bug two times (I messed something up with my browser).
Hi Vincent Looking at your launchpad bug it seems that you're using old version of xserver-xorg-video-nouveau(1.0.7), amongst others. Can you update to: * libdrm 2.4.52 * Mesa 10.0.3 * xserver-xorg-video-nouveau 1.0.10 Additionally does the pink line appear in VT or is it present only within X ?
I wonder if playing with xrandr settings will make the line go away. Take a look at "xrandr --props". Things like "scaling mode" and the various "underscan" stuff.
Line is visible in VT. No changes with xrandr.
(In reply to comment #7) > Line is visible in VT. No changes with xrandr. Ubuntu 14.04 versions: mesa = 10.1.0~rc1-1ubuntu3 xserver-xorg-video-nouveau = 1:1.0.10-1ubuntu2 libdrm = 2.4.52-1

Created attachment 95180 [details] dmesg with nouveau debug info This debug output was created by adding 'nouveau.debug="PDISP=trace,I2C=trace,VBIOS=trace"' to the kernel commandline.
Same problem here, with my K1000M. It actually doesn't happen after startup, just when I lock and unlock. I have been able to fix the problem by switching terminals, starting X, killing it and switching back to my normal session.
I can confirm i have this happening with my GeForce GTX 780 Ti (GK110B) connected over HDMI to my Asus PB278Q monitor running Arch linux (3.16.1-1-ARCH). xf86-video-nouveau 1.0.10-3 nouveau-dri 10.2.6-1
I just posted a tentative fix on nouveau mailing list: http://lists.freedesktop.org/archives/nouveau/2014-September/018654.html Beware, it hasn't been reviewed yet, values may be specific to my card/setup. Also, I only enabled my change on nve0 cards, so GTX 780 is likely to see no change.
Looks like Ben made a more complete fix, now available as part of http://cgit.freedesktop.org/nouveau/linux-2.6/log/?h=linux-3.18 More specifically http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?h=linux-3.18&id=a522946174b5ae389af0856c422d865a63c70316 Please test & confirm.

I built & ran, but I hit a panic - which may not be related to nouveau: I booted with blob and got a panic ending with "recursion stopped but you need to reboot" or so message. With nouveau it booted just a past nouveau initialisation before panic'ing again (I had the time to see at least 3 panic/oops messages scroll by, like 500ms from each other), so I could at least see the HDMI initialising properly on HDMI-1 in console. I didn't test other outputs, HDMI audio, and different resolution. I'll be away for 3 weeks starting tomorrow, so sadly I won't have much time to test further until then. BTW, isn't "ret" returned uninitialised in the "else" branch of "if(nvif_unpack(args->v0, 0, 0, false))" ? Or is there some macro magic ?
Hello, this issue is closest to the one I'm experiencing. There is a pink line at the left of the screen. But it appears as soon as X starts and additionally the rest of the screen seems to be shrinked by just those few pixels. This means alternating regions of sharp and blurry image (just horizontally). Just up front, my graphics card is an AMD Radeon R280. And I see this only with latest kernel version. So maybe the guys who work on the radeon driver just introduced a similar issue. There are no error/warn/fail messages in dmesg and playing with xrandr won't change anything. Even restarting X doesn't change a thing.
found the solution to my issue. seems to be a bug with HDMI audio enabled by default. see https://bugzilla.kernel.org/show_bug.cgi?id=93701 sry for the distraction
This bug should have been fixed in ~3.18 or so. Re 'ret' being special, it is, see nvif_unpack macro definition. Feel free to reopen if you're still seeing pink lines on Kepler GPUs.
