XFCE4 - lightdm - light-locker - No cursor after unlock

I installed xfce4 recently, using lightdm as display manager and login manager, and light-locker to manage locking
I have an issue with my mouse cursor, if I let my laptop to lock automatically or use command

 light-locker-command -l 

To lock, when I come back i have no mouse cursor, i have mouse but it is invisible, i can see icons reaction by moving the mouse, but no cursor

If I logout manually (not locking) and login again, i have cursor again!

It is really annoying! Can anyone help me?

Re: XFCE4 - lightdm - light-locker - No cursor after unlock

I don't have a solution, but you might mention what video hardware you are using and which driver you are using for it.

Re: XFCE4 - lightdm - light-locker - No cursor after unlock

I have exactly the same issue on my Lenovo T460 with an Intel integrated GPU.

00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 07) (prog-if 00 [VGA controller])
    Subsystem: Lenovo Device 5053
    Flags: bus master, fast devsel, latency 0, IRQ 127
    Memory at f0000000 (64-bit, non-prefetchable) [size=16M]
    Memory at e0000000 (64-bit, prefetchable) [size=256M]
    I/O ports at e000 [size=64]
    Expansion ROM at <unassigned> [disabled]
    Capabilities: <access denied>
    Kernel driver in use: i915
    Kernel modules: i915

No cursor after lock is annoying, but I also get frequent crashes/freezes coming out of standby.

This is a problem with xorg-server 1.18.2. It is reported (with a workaround) here: https://bugs.freedesktop.org/show_bug.cgi?id=94677

Re: XFCE4 - lightdm - light-locker - No cursor after unlock

I've uninstalled xf86-video-intel and removed /etc/X11/xorg.conf.d/20-intel.conf; let's see if this changes anything.

This works like a charm! No more freezes, and always a cursor

Re: XFCE4 - lightdm - light-locker - No cursor after unlock

I've uninstalled xf86-video-intel and removed /etc/X11/xorg.conf.d/20-intel.conf

when i remove them, i have screen flickering on startup and on scrolling web pages

Re: XFCE4 - lightdm - light-locker - No cursor after unlock

Same stuff is disabled/software, plus this on the Intel driver:

Multisampling is buggy in Intel IvyBridge: 116370
Applied Workarounds: disable_chromium_framebuffer_multisample

Raster is using a single thread.
Disabled Features: multiple_raster_threads

I'm staying Intel-driver-less

Scrolling works perfect here; I did disable that sluggish "smooth scroll" nonsense.

I also don't feel the need for a boot animation/graphic, so I disabled that too

Okay, but...   What video driver are you using?   fbdev?

You might check the output of glxinfo  (part of mesa-demos).  You might be less than thrilled with the results.
tl;dr  This is fine for troubleshooting, but no a good solution.

Probably the "modesetting" driver, which has some support for OpenGL too.

And glxinfo has an output of 379 lines, of which I only understand "direct rendering: Yes"
