[SOLVED] Screen tearing on multi-monitor setup....

HI Guys..

I have really bad screen tearing on a multi-monitor setup running XFCE. I have my main monitor plugged into my nvidia cards vga port & my vertical monitor plugged into my on-board intel vga port. I have tried creating both /etc/X11/xorg.conf.d/20-nvidia.conf & /etc/X11/xorg.conf.d/20-intel.conf with the code below, but my desktop fails to load when either file is present. I simply get dumped to a blinking cursor, but can switch to another TTY & remove both of those files to boot back into my desktop once again. I've tried also loading the nvidia-setting gui app & enabling Force Composition Pipeline there, but that only helps for the nvidia monitor & I still need to open the app & re-tick the option again after every reboot. I've also enabled nvidia-persistenced, but that didn't seem to help with anything....

NVIDIA....

Section "Device"
    Identifier "Nvidia Card"
    Driver     "nvidia"
    Option    "metamodes" "nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}"
    Option    "AllowIndirectGLXProtocol" "off"
    Option    "TripleBuffer" "on"
EndSection

INTEL....

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"    "true"
EndSection

Re: [SOLVED] Screen tearing on multi-monitor setup....

You shouldn't have either of these files and you shouldn't have xf86-video-intel installed. What you'll want to test instead is whether you can enable PRIME Sync by enabling KMS on nvidia: https://wiki.archlinux.org/title/NVIDIA … de_setting

FWIW can you post

xrandr --verbose

and a xorg log from your current setup?

Okay so I don't have xf86-video-intel installed on my system & here's the output for xrandr --verbose....

Yes try enabling KMS, any particular reason you are splitting things this way? You'll get more deterministic behaviour plugging all screens into the same card.

Re: [SOLVED] Screen tearing on multi-monitor setup....

So I just added added nvidia_drm.modeset=1 to /etc/default/grub & then ran sudo grub-mkconfig -o /boot/grub/grub.cfg. Rebooted & still got screen tearing on both monitors. Hmmm yes I should really just plug both monitors into the nvidia card. The only reason I have done it this way is because my nvidia card only has 1 vga port. Would it matter at all if I bought a dvi cable & connected my other monitor to the dvi port on the nvidia card ??

Mmm... For what my experience is: no, not at all. But let's wait for the some experts here

Consider running the server on the intel chip.

Thanks for the link. Reading it now. Also I just ordered a dvi cable from amazon so I may wait & see if that works first....

Re: [SOLVED] Screen tearing on multi-monitor setup....

HI Guys. Sorry for the late reply. Amazon messed up my package, but it finally arrived last night. Both monitors are now plugged into the nvidia card & everything works perfectly. There is no screen tearing or funky business....
