kwin randomly crash with zeroing (or resetting) graphics message

On my son’s laptop, an asus vivobook pro N552VW-FY204T, i7 6700HQ Processor, 16Gb RAM, graphic intel HD Graphics & NVIDIA GeForce GTX 960M with 2G/4G GDDR5 VRAM (I suppose that intel HD is used, becouse I unstalled bumblebee that worked badly), running leap 42.2, plasma5.9.5, kde framework 5.33.0, kernel 4.4.62-18.6-default, libreoffice 5.2.5.1,
often (using libreoffice but not only) kwin crashes with this message:
http://paste.opensuse.org/view/download/81817255
that translated from italian sound approximately:
title_________________________|description
zeroing (or resetting) graphics
| a zeroing (or resetting) graphics error has occurred
composition has been suspended_| another application has requested to suspend the composition

is there a way to solve this??
manythanks, ciao, pier :slight_smile:

What you show here is no error or crash dialog.

It’s the configuration dialog for kwin’s notifications…

did you try setting uxa as the proffered acceleration method?
create /etc/X11/xorg.conf.d/20-intel.confI

kdesu kate /etc/X11/xorg.conf.d/20-intel.confI 

and paste this

    Section "Device"
        Identifier  "Intel Graphics"
        Driver      "intel"
        Option      "AccelMethod"  "uxa"
    EndSection

don’t have an optimus rig but I do think bumblebee (with the propitiatory nvidia driver not noveao) is needed
another option would be to replace kwin with openbox or disable all compositing and use software rendering but that would degrade performance

…but this is what appear when everything is blocked for few seconds :slight_smile:

yes I did, but it doesn’t works at all :expressionless:

well, I don’t know if it is optimus, but, I tried to install bumblebee but it doesn’t works at all… so I uninstalled it.

it’s probobly optimus as all intel+nvidia laptops are optimus now days
how did you install bumblebee did you install the nvidia drivers or did you keep noveau?
I’d say retry to install bumblebee according to the new wiki
https://en.opensuse.org/SDB:NVIDIA_Bumblebee
including the propitiatory nvidia codecs

if not sure it’s optimus go in bios and see if you can switch off intel’s graphic an older helpful video

did you maybe install nvidia driver the hard way as mixing may cause issues

I just remembered Skylake had issues with the Linux kernel
according to the arch wiki the best bet is to disable hardware acceleration on skylake chips
https://wiki.archlinux.org/index.php/intel_graphics#Skylake_support
edit the above file /etc/X11/xorg.conf.d/20-intel.conf to

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option        "DRI"    "false"
EndSection

afaik TW has better skylake support a switch to TW might be a better choice

edit
another option is to add

i915.enable_rc6=0

to the boot parameters you can do this with yast

yes, I followed the new wiki installing the nvidia proprietary driver from bumblebee repo as described in the new wiki, but at that time resulted very better the behaviour without bumblebee

as soon as I have the laptop in my hands I will try.
so, as I understood, I can have as my primary card the nvidia card and then install the nvidia driver from the leap 42.2 repo in the classical way??

no, no hard way nvidia install…

manythanks, as soon as I have the laptop in my hands I will try also this
