Screen tearing in XFCE

buntolo · 2014-08-20 01:16:24

I have screen tearing when scrolling pages, it is more noticeable when scrolling Google's search result in Firefox.
I have read: https://bbs.archlinux.org/viewtopic.php … 8#p1251858
And tried installing xfwm4-vsync (https://aur.archlinux.org/packages/xfwm4-vsync/) but it does not seem to work.

Then I have read: https://bbs.archlinux.org/viewtopic.php … 8#p1259058
And tried with:

$ xfconf-query -c xfwm4 -p "/general/sync_to_vblank" -s true

but it says that «/general/sync_to_vblank» does not exist in «xfwm4». it suggest to create a new property with --create
If I try with:

$ xfconf-query -c xfwm4 -p "/general/sync_to_vblank" -s true --create

but it then asks for a value to assign to --create and I do not know what to do.

What could I do now?

What version of xfwm4 are you running? The sync_to_vblank feature made it into the 4.11 version - the gui setting is located on the Compositor tab in Window Manager Tweaks.

There is an xfwm4-devel 4.11 version in the AUR that should have the fix included.

If by "I have vsync" you mean screen-tearing, I use compton-git from the AUR to good effect (Intel HD4600):

compton --backend glx --vsync opengl-swc

If you decide to use this, disable the native xfce compositing first...

Yes I have screen tearing issues, it was late and I wrote badly, I am going to correct the opening post right now.
My problem: http://en.wikipedia.org/wiki/Screen_tearing

I have xfwm4 version 4.10, this should explain why vsync is not working:

$ pacman -Qi xfwm4

I have read this: https://wiki.archlinux.org/index.php/Ar … Repository
But still I do not understand something...
Now xfwm4 is in extra: https://www.archlinux.org/packages/extra/x86_64/xfwm4/
If I install 4.11 from AUR what will happen when it will be included in official repository? Will xfwm4 come in extra? Do I need to remove the AUR package and re-install it from the official package?

To get the commands to output in English, use:

LC_ALL=C <command>

If you have intel graphics you can always use TearFree option (see intel graphics in Arch Wiki). Compton-git is good for tearing only if you need compositor.

Already done:

$ cat /etc/X11/xorg.conf.d/30-intel.conf 
#/etc/X11/xorg.conf.d/30-intel.conf

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

Are the only solutions available installing xfwm4 4.11 or using compton as window manager?
If I install xfwm4 4.11 from AUR what willl happen when it will be stable and come in official repository?

Compton is a standalone compositor that can be used instead of the built-in xfce compositing system.

You are doing it wrong. This should be 20-intel.conf not 30-intel.conf. Check wiki again. TearFree option is also faster than using compton. This is how suppose to conf file look like:
https://wiki.archlinux.org/index.php/In … free_video
Also EndSection is missing.
Edit. Almost forgot, Vsync has to be enabled, but it is enabled by default so unless you haven't changing anything than it should be enabled.

EndSection is correctly placed in the .conf, I just made en error copying it here.

Naming it 20 or 30 change nothing, it will only influence the executing order of the .conf in xorg.conf.d.
