Brightness and sleep don't work after update

Hi! I recently switched to linux59 and I’ve started to notice that my laptop isn’t waking up from sleep (my keyboard lights up, but the screen remains black) and that my screen brightness controls have stopped working (I get the pop up whenever I adjust the brightness, but it doesn’t seem to have any effect). This only seems to happen when I’m using linux59 (I tried to replicate it with linux54 and linux58 unsuccessfully), so I’m guessing it has something to do with that.
I’m a bit new to manjaro, so I’d greatly appreciate any help.
Thanks!

Here’s the output from inxy -Fazy:

Hello,

Hi,

I have been using Manjaro for a little while now and I am seeing a lot of problems with upgrading and kernel upgrades above the LTS. The newest kernel 5.9.10 and the first one before it 5.9.8? sleep does not work for me. If you put it to sleep or it does itself after time, my screen opens to black and the only thing I could do was it ctrl-alt-delete, maybe. it would shut down. or I just had to hold the power button for 10 seconds to kill it and then restart. It is unusable. I had to go back to the LTS 5.4.x kernel and that works.

other problems I have had with newer kernels are that suspend does not even suspend. I close the lid and the system keeps running. I have had my laptop get extremely hot which also seems to be a kernel version issue.

I generally like to upgrade when they come, but I find that is just not safe with Manjaro.

If you upgraded a kernel and need to back out/change the one used you can add or remove kernels
in Manjaro Settings, pick kernels. then install/remove

then to set your boot up defaults; install and run: grub-customizer
