Description:

Sometimes after waking the screen or similar instead of the password prompt, a completely white screen is shown. That screen doesn't allow you to unlock the screen, you have to switch to another tty and kill the light-locker.


Additional info:
* Version: 1.6.0
* Desktop environment: XFCE 4.12
* Downstream distro: Antergos (it doesn't modify the package in question, though)


Steps to reproduce:
1. Wait for the screen to lock and go to sleep
2. Wake it with a mouse or keyboard
3. Sometimes a white screen will be shown
This task depends upon

This is more likely your X driver. Which one do you use? What do the logs say when this happens?

nvidia-340xx.

Which logs should I watch when this happens?

The journal would be the most important, but you can watch dmesg as well, there could be something there.

I found an interesting thing in the dmesg:

[39117.412289] WebKitWebProces[31966]: segfault at 1c8 ip 00007f09071d67ee sp 00007ffe409e9960 error 4 in libGL.so.340.96[7f0907128000+c7000]

So the greeter is causing problems. That greeter doesn't exist in Arch, it's done by Antergos. This is why derivatives are not supported here.
