Strange behaviour with 2 screens and linux & nvidia update

whizzo · 2015-09-28 21:39:22

Hello, sorry about my bad english.

I update my system with:
[2015-09-28 08:59] [ALPM] upgraded linux-firmware (20150722.e10097a-1 -> 20150904.6ebf5d5-1)
[2015-09-28 08:59] [ALPM] upgraded linux (4.1.6-1 -> 4.2.1-1)
[2015-09-28 09:00] [ALPM] upgraded nvidia-libgl (352.41-1 -> 355.11-1)
[2015-09-28 09:00] [ALPM] upgraded nvidia-utils (352.41-1 -> 355.11-1)
[2015-09-28 09:00] [ALPM] upgraded nvidia (352.41-1 -> 355.11-2)

And now, in my dual screen system, the left screen (DVI) is ok, but the right one (VGA) has a strange resolution, and when no pointer and no windows on that screen it darkens, when I move the pointer at right screen, lights again.

I downgrade to old versions in thats aplications.

Same here. There's a problem with the Nvidia update that came yesterday and people with 2 screens.

persy89 · 2015-09-29 11:30:26

I have the same issue: 2 vertical black bars in the secondary (VGA) monitor even if nvidia-settings has set the right resolution

Seyaku · 2015-09-29 12:58:52

Having the same issue. First monitor is OK, second monitor (VGA) output is stretched and misaligned. Lowering the resolution shows black bars. Was working before the update.

mauritiusdadd · 2015-09-29 16:02:53

It happens also here with two nvidia GTX 550 in SLI mode, with only one monitor connected to the VGA port of the first card: using a resolution higher than or equal to 1680x1650 at 59.95Hz (the monitor native resolution) the display area goes outside of the screen (screenshot). If I override the refresh rate with any other value than the default one, the screen is displayed correctly but it has a resolution different from the one specified by xrandr. I tried to rebuild the nvidia packages manually but nothing has changed, so it appears to be an upstream bug which affects only the VGA output. Everything works fine with the same monitor using the HDMI port.

Yeah I have the exact same thing on my second screen which also happens to be connected via VGA.

Same here, my second screen have an output, but the image is really ugly and text appears broken, I'm at 1366x768.
Can't downgrade, I'm waiting for a solution.

hexdsl · 2015-09-30 21:49:46

same issue here. i have 4 monitors, every one except primary are ugly now (black bars at sides) - tried BETA drivers, does not fix problem

edit: Only appears to effect monitors at native resolutions. I lowered resolution on other screens, looks okay, will do until fix

Hi,

Having same issue since my latest system update from yesterday (see bellow) multi monitor is not working anymore (I tried VGA + DVI output), I was simply using gnome preferences and just worked until yesterday.
Any idea ?

It happens to me exactly the same WITH JUST ONE MONITOR too, a VGA monitor. My monitor just have VGA input so I can't check the HDMI port or anyone else.

The nvidia 355.11-2 --> 355.11-3 update haven't solved anything.

hexdsl · 2015-10-01 07:45:17

does anyone know if this 'bug' has been reported?

ambro · 2015-10-01 09:51:41

I had the same problem with 1 monitor connected with VGA. I use ck kernel.

I downgraded kernel and nvidia packages and the problem disappeared!
I downgraded to these versions:

pacman -U linux-ck-bulldozer-4.1.8-1-x86_64.pkg.tar.xz linux-ck-bulldozer-headers-4.1.8-1-x86_64.pkg.tar.xz

pacman -U mesa-10.6.7-1-x86_64.pkg.tar.xz

pacman -U nvidia-utils-352.41-1-x86_64.pkg.tar.xz nvidia-libgl-352.41-1-x86_64.pkg.tar.xz lib32-nvidia-utils-352.41-1-x86_64.pkg.tar.xz nvidia-ck-bulldozer-352.41-2-x86_64.pkg.tar.xz opencl-nvidia-352.41-1-x86_64.pkg.tar.xz wayland-1.8.1-1-x86_64.pkg.tar.xz

I wait for solution. If yuo need tests I'm available.

It seems that the problem could affect also the monitors connected to the DVI port (see: https://bbs.archlinux.org/viewtopic.php?id=203074). I don't know if there is an official bug report, but there is a thread on the Nvidia forums which describe a similar issue https://devtalk.nvidia.com/default/topi … itor-setup.

oxhak · 2015-10-02 04:30:30

I think we need to say that to nvidia, I'm going to post on the devs forum, this is a screenshot of my strange issue, my screen is an automatic adjustement screen so no black borders, but you can see the text appears in a bad resolution or aliased text, but that's not normal and just happen with linux nvidia 355.11 driver.

I've created an nvidia topic here

yupi · 2015-10-02 09:11:47

Hi guys!

This does not seem to be nvidia-only problem (as fguerout's comment already suggests).
I have DELL LATITUDE E7450 and a ViewSonic monitor connected via VGA (in fact to a dock) and
I have the blank external monitor problem with the new kernel (4.2.1). (That is, external monitor gets detected but stays blank.)

Downgrading kernel back to 4.1.6 helps.

The graphics is Intel® HD Graphics 5500 (Broadwell GT2)

Hello!

Lately I've upgraded my Antergos to 4.2.1 kernel and my nvidia driver to 355.11. I'm using a single monitor that is connected to my PC via VGA. When my PC rebooted I've noticed that I have 2 black bars on left and right when using my native resolution(1440x900) at 60Hz refresh rate but when I switch to 75Hz the black bars disappear and my screen looks normal.

hexdsl · 2015-10-03 14:44:41

has anyone found more information? is there a solution to this yet? I don't really want to downgrade, that's not a long term solution

fguerout · 2015-10-03 15:23:06

try upgrading (kernel has been updated), it worked for me

What kernel are you using? I'm using 4.1.9-1-ck and the stock 4.2.2-1 and neither of the two works. Also do you actually have a nvidia card?

fguerout · 2015-10-03 15:34:39

linux 4.2.2-1 with intel integrated chipset works now ok

mauritiusdadd · 2015-10-03 17:20:17

Sorry, I missed your post above where you told you were using an Intel card. However, I'm glad that linux 4.2.2 works for you and I hope that also the nvidia developers find a solution too.

lukasm · 2015-10-04 08:12:07

Hi all

I also have the same problem. My monitors are both VGA, but with an adapter attached to my GPU with the mentionned upgrade. The left screen is shifted to the left and I cannot shift it back. Sometimes there are parts of the screen missing at the right border of the left screen, but then suddenly this gap is filled again.

I have installed the latest linux, so I will just downgrade again.

Kind regard
Lukas

I am having the same issue. Nvidia 560Ti with a Viewsonic VX2025wm on a VGA connection. Ran an update last night and it upgraded to kernel 4.2.2-1 and Nvidia 355.11 and I ended up on 1680x1050 resolution but with black large bars down the sides and it all squashed up. I can also confirm that it is only my native resolution which is affected and changing to any lower resolution gets rid of the black bars but leaves me with a significantly lowered resolution. The only way I have been able to sort this out is to go into the Nvidia X Server settings GUI utility and in the X Server Display Configuration tab change my selection from my Viewsonic display to "X Screen 0". That now has me back onto my 1680x1050 with no black bars.

Thanks Supay. Your workaround is great.
I'have saved X configuration file in /etc/X11/xorg.conf.d/99-nvidia.conf and all is ok. The login screen of sddm too.
Waiting for a bugfix by nvidia developers it's a great workaround that permit to continue upgrading packages.
