Black screen after unlocking Linux

Hello everyone.

I have a problem with the screen unlocking. When I close the laptop lid, it locks. When I open it, and enter the password, the screen turns off, but it still works. I know this because I turn it off by opening a terminal and entering the command "init 0", then the screen turns on and shows the distro logo. When I turn it back on it works perfectly.

Thanks if anyone can give me information on how to fix this problem.

I'm using Linux Lite 5.6, with Xfce4 v4.14

Re: Black screen after unlocking Linux

Which screensaver/locker are you using?
Which video card and driver?

Re: Black screen after unlocking Linux

I already solved the problem by installing "xscreensaver", but if you have any idea of the cause, I would like to know anyway.

I'm using these

light-locker (1)     - screen locker
light-locker-command (1) - controls light-locker
xfce4-screensaver (1) - The Xfce Desktop Screensaver and Locker

and the video card is

VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (re>
        Subsystem: Lenovo 2nd Generation Core Processor Family Integrated Graphics Controller
        Flags: bus master, fast devsel, latency 0, IRQ 26
        Memory at e0000000 (64-bit, non-prefetchable) [size=4M]
        Memory at d0000000 (64-bit, prefetchable) [size=256M]
        I/O ports at 3000 [size=64]
        Expansion ROM at 000c0000 [virtual] [disabled] [size=128K]
        Capabilities: <access denied>

I've seen numerous reports about issues like this caused by light-locker.
