Dear Maintainer,

I have installed Debian Trixie with KDE/Plasma 6.3.5 on a HP Pavilion laptop.
After I close the lid the laptop suspends to ram succesfully.
Then when I open the lid to wake up the laptop all goes well, except that the touchpad is turned off.
Not only is it turned off, but in KDE/PLasma systemsettings the touchpad is then also disabled (the checkbox to enable the toucpad is not checked).

Since I had this problem too on Opensuse Tumbleweed with simular KDE/Plasma version and kernel version.
And this does not happen when I suspend and wake up using Icewm and not KDE/Plasma.
So I think that this is a problem with KDE/Plasma.

This problem happens on both a X11 and wayland session, and running on ac-power and on battery.
And it never did for years on multiple Linux distros including Debian Bookworm running KDE/Plasma 5.x.

So it seems like a regression in KDE/Plasma 6.x
My appologies that I can not be more specific as I really do not know what is causing this.

Thank you for your time,
Chris Maaskant.

I'd say this must have something to do with your specific hardware. At least it's not a widespread issue for sure and it's the first time I hear about this.

That you see it now may be related to Plasma 6 but it may also come from newer kernels and Plasma triggering some issue with these.

If you could share the bits of the system logs before sleep / after wake that would probably be useful.


Happy hacking,

I have installed Opensuse Tumbleweed now on my laptop.
I have reported these 'problems' on discuss.kde.org since it does not
seem to be distribution specific.
But if there is a solution posted there, I will report that here also.
