Hi all,
I am trying to get FreeBSD running one of my Thinkpads, the X201. I can get the machine to suspend but upon resume the screen is black. I can SSH into the machines just fine so it does come up, but I can't get the screen to come alive.
Looking on the forum some people recommend to run "sysctl hw.acpi.reset_video=1", so I tried this and suspended a second time. It goes to sleep ok, but upon resume the machine is completely unresponsive (can't SSH, not even the caps/scroll/num lock LEDs turn on when buttons are pressed) requiring a hard reboot.
This seems to be a common fault across all my machines. I've also tried with a T490 laptop and my Desktop (see here) all of which seem to have this issue
According to the FreeBSD laptop compatibility wiki, both the T490 and X201 entries state that suspend/resume works. So I must be doing something wrong. Is there any specific configuration I need to do to get it to work on the X201?
All I've found so far is on https://wiki.freebsd.org/SuspendResume, where they say if resume does not work to reset my BIOS and try again, which I've done with no change.
