KL2 - wake from sleep not working with no sleep cover when screenshots are enabled

ajkessel · 09-26-2025, 10:31 AM

I recently did a factory reset on my KL2, updated to latest firmware (4.38.23429 8/18/25), and installed KOReader, Nicklemenu, and KFMon. I also set screenshots=true in Kobo eReader.conf.

Ever since then, I was unable to wake the device from sleep. I'm not using a sleep cover and have sleep cover disabled in settings. The only way I could get the device to work from sleep mode was to long-hold the power button until it rebooted.

I finally figured it out when I noticed that I had dozens of screenshots stored on my device that I had not intentionally created. The screenshots all showed the sleep screen. I disabled screenshots and then wake-from-sleep started working fine again.

So apparently what was happening is pressing the power button while sleeping was taking a screenshot rather than waking the device.

Has anyone else seen this? Is this a reportable bug? Is there some workaround short of just disabling screenshots?

It's how it's meant to work. The Screenshot is created by sleep/power button. Thus you need to have a sleep cover, or connect to PC and edit it off when you are done with screenshots.

Or use NickelMenu to toggle the setting...

This is one of the nice things about the KLC; the front buttons can also wake the device...
