I have a fresh install of arch on a thinkpad t410, and I am having a problem with trying to get the system to suspend when I close the lid. I've been trying to debug it for days and can't figure out whats wrong, even after reading the wiki and trying multiple different things, so I am asking here.
I have bspwm, light-dm with the gtk greeter, and slock.
When I close the lid and open it, I am met with a black screen, no backlight or nothing. I also see on the lid that the wifi led indicator is off, which is normally blinking, and the caps lock key led does not toggle on and off when pressed, which leads me to believe that the problem is a little deeper than just the display. I've tried fruitlessly to get a tty or end X or something, the only think I can do is hold down the power button and reboot.
If I close the lid and wait, eventually I think the laptop goes into hibernate or at least tries. If anyone has owned a t410, you will know that when the lid is closed, eventually when it goes into hibernation the LED crescent moon indicator turns on (on the back of the lid next to the battery indicator), and the fans stop. If I close the lid and wait for this, and then open the computer again, I get a black screen with backlight. If I move the mouse or hit a key, the screen turns blue. if a hit another key, it usually turns red. it will continue switching colors between red and blue when keys are pressed. I have been able to get to a tty from here, but I don't really know what to do after this. I'm not new to linux but i'm new to arch.
I tried switching to the LTS kernel, which went flawlessly, but didn't change the problem whatsoever. One thing that I suspect might be related to the problem is that when I run
journalctl -b -0 -p err..alert
I see that there is an error logged that says
failed to get backlight or LED device 'backlight:acpi_video0': no such device
my backlight is called nv_backlight, and I know from looking at other logs that right after looking for "acpi_video0", it looks for "nv_backlight" and finds it. I have been able to successfully change by brightness and everything, my backlight is definitely on, accept if I close my laptop and open it. I don't know if this error is a related to my suspend problem or if it is a red herring.
Sorry for the long-winded post. I'd be more than happy to post any other logs or output from commands that might help the diagnosis, but I don't really know which ones would help at the moment, if any.
