I'm having a bit of a problem on my laptop. I run FreeBSD, just upgraded from 14.3 to 15 yesterday. So both systems run kde/plasma 6.5.x on X11 (just upgraded from 6.5.3 to 6.5.4 last night).
or
On my desktop, (Ryzen 7 5800x, 64GB RAM, nVidia RTX3060Ti), everything runs perfectly. The problem occurs on my laptop, which is a Lenovo Thinkpad W520, with the i7-2760QM, 32GB of RAM, and although it has an optimus setup, the intel GPU is enabled and the nVidia discrete GPU is disabled in bios. I also made sure the nvidia drivers were removed.
So what I am seeing is that while I am using the laptop, it is fine. However, when I stop using it, either closing the lid, or running an errand, when the screen blanks and comes back, I am able to move the mouse, but the the mouse buttons and keyboard are inoperative within the X session, and clicking a terminal window, mouse tab, etc., does not shift focus...The system, when it is working as expected, is using about 5MB (16%) of RAM. However, after running with the lid closed over night, idling, and the memory usage goes above 65%.
The problem can be fixed by jumping to one of the VTs and restart the login manager. I have tried switching that between SDDM and SLIM, and it occurs in both. As far as I know, plasmashell continues to run, but most times I get two core dump files in my home directory:
and the one on the drkonqi core:
Unfortunately, I am a sysadmin, and not a programmer, so I have no experience with debugging core dumps.
Has anyone got any suggestions on a possible cause? Note that I did not see this problem when running 14.2, however when I upgraded to 14.3 and then 15.0, it has been happening with regular frequency.
Thanks
