I recently decided to give FreeBSD 14.2 a try on an old ThinkPad, figuring that, given its age and its popularity, it would be well supported. I was able to install FreeBSD 14.2 with a ZFS mirror and KDE; however, I'm experiencing issues with sleep mode and I'm not sure where to go from here. When I close the lid, the laptop does not enter sleep mode (the sleep indicator light on the lid does not turn on). Strangely, when I open the lid, the system then enters sleep mode with the lid open. If I press the power button, it resumes from sleep and SDDM briefly displays the login screen, but then the system immediately goes to sleep again. Pressing the power button a second time brings it out of sleep, and the SDDM login screen appears as expected.
