Xfce compositor causes freezes after reopening my laptop lid

Hello everyone,

I am new to this forum, so I apologize if I ask any silly questions. I have recently installed Gentoo Linux on my ThinkPad T480. With it, I installed Xfce as its desktop environment. While it seemed at first like there weren't any issues, I found one, and a major one at that. When I closed my laptop lid and reopened it, it, for some reason, defaulted to a blank screen, with no way to escape it aside from Ctrl+Alt+F4. After restarting, I went to the Power Manager and switched the "When the laptop lid is closed:" option from "Lock screen" to "Suspend." Once I closed and reopened my laptop lid, I wasn't met with a black screen. The lock screen didn't open (I had the lock screen enabled), and I couldn't interact with my desktop, except for my mouse cursor. I am unsure of what's going on or why. Does anyone have any ideas why this is happening, or maybe even know a solution?

Here's the output of inxi -Fxxxrz, since I saw someone else in the forum do that:

Thank you in advance for any help!

UPDATE:

As it turns out, the problem seems to stem from the compositor. Has this been a problem before with the compositor? While I can settle without it, I do like it and would prefer to get it fixed. Any additional help is appreciated!

Re: Xfce compositor causes freezes after reopening my laptop lid

My first guess would be that it's a LightDM issue, unrelated to Xfce.

Also, your swap partition is 16GB, should be at least 64GB.

Maybe also try disabling the compositor.

After doing a few tests. I am 99% sure it's the compositor, like you said. But then, that opens another question: Why is the compositor doing this?

Re: Xfce compositor causes freezes after reopening my laptop lid

For testing you can disable the compositor in the settings.

There was a similar problem with the xscreensaver. Switching to xfce4-screensaver fixes it. Also, there was an issue a while back with lightlocker, xfce4-screensaver fixed that too.

Lightdm can also handle screen locking easily.

I couldn't tell you, but it seems like every single freezing issue with Xfce comes down to compositor. Since you don't have an nvidia card, maybe try just disabling vsync instead of the entire compositor.
