The Issue: Since March 11th, i've noticed that when trying to wake my pc from a "suspended" state i'm met with a black screen, mouse pointer is present. Clicking mouse buttons or keyboard keys causes the "digital keyboard" to pop up for a split second then disapear again.

here is the current:

I've run an update while writing this post. however, I've updated several times since experiencing this issue to no avail.

That’s an interesting clue; the on-screen keyboard has been set up in the default screensaver configuration. I have never had the issue you are describing, but then again the screensaver lock screen is disabled in my XFCE installation.

Try turning it off in the screensaver settings and see if it has any impact on the issue:

a quick & very brief test suggest this work around should avoid the problem. However, doesn’t really solve the issue. I wounder if switching to Xscreensaver and removing the default would be an alternative “fix”?

5

Can you explain what you mean by that?

Specifically: how does the issue present itself when the screensaver lock screen is disabled?

6

The issue isn't just with the lock screen apparently. I've been gone for a few hours only to find that the screen saver didn't run. As for the issue, I would like to have a lock screen with screensaver simply because family is a problem atm. with out it I have other issues, with it I have to reboot; i'm still to new to figure out how to get a terminal prompt up, login and get all the nice gui stuff back up.

Gotcha, that's fair enough.

Test if changing to the s2idle suspend mode allows a normal resume from suspend. You can do it right from the Garuda Boot Options app.

Find the line that says "Kernel parameters" and the value mem_sleep_default=s2idle. Add it at the end of the line, after whatever is already on there. Then click Apply at the bottom.

After that, I would go back to your screensaver settings and re-enable the lock screen since you noted you will need to use that.

Reboot, then in the fresh reboot test if you get a different result waking from a suspend state.

Hi @Ichino, it turns out this is a known issue with the XFCE screensaver which was very recently fixed, see here:

It sounds like an updated package with the fix should land some time this week or next.

If you would like a temporary workaround until then, consider installing a replacement screensaver:

sudo pacman -Rsu xfce4-screensaver
sudo pacman -S light-locker
