Comment 0 for bug 1591260

Hi,

I have been investigating and trying to find a solution to this problem, and since I didn't find an existing bug report, I figured I'll do on.

The problem is that I am experiencing screen tearing/lag/pixeling with my new Dell Precission 5510 Laptop which is using this configuration:

artur@pandaadb:~$ lspci -k | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06)
 DeviceName: Onboard IGD
 Subsystem: Dell Skylake Integrated Graphics

 Kernel modules: nvidiafb, nouveau, nvidia_361
02:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)

artur@pandaadb:~$ uname -a
Linux pandaadb 4.4.0-22-generic #40-Ubuntu SMP Thu May 12 22:03:46 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

A bit more info maybe on this:

I have been trying drivers with these versions:

367.18
361.45
364.19

All of those have the same problem:

* Video tearing when watching video on netflix/youtube
* Scrolling in browsers appears laggy. I am unsure how to best describe it, but it appears like the redraw of the screen is too slow and you can see the redraw like a wave.
* Terminal can't keep up with typing, neither can the browser (this actually is better in 367 which I am aware is not officially supported yet)

I also believe that the driver/gpu causes a similar bug crashing the entire system randomly. However I am not sure how to confirm that.

I created a related post with some info here: http://ubuntuforums.org/showthread.php?t=2327162&p=13500945#post13500945

I tried as a workaround several "fixes" found online, non of which have any effect other than sometimes crashing the entire system and the system not starting up anymore.

E.g. I did:

nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceCompositionPipeline = On }"

I tried several other fixes that are documented here: http://www.iwillfolo.com/finally-nvidia-tearing-issue-fix-found/

they also did not work.

This is a rather frustrating problem and I don't know if there is a workaround. If there is something you would like me to try, I will be happy to do so. Any workaround would make my day :)

Thanks!
