The screen of my laptop goes black when it wakes up from suspend. I don't think that the laptop freezes because I can do REISUB. I suppose it's a problem with the brightness, but I could be wrong.
Some of the things I've tried include turning up the brightness via the corresponding shortcuts, booting using nomodeset, pressing the Ctrl+Alt+F1-F12 shortcuts, and uninstalling Redshift. But, none of them did anything.
I guess I could try going into TTY, but I don't know what I'd enter.
A few things that might be worth noting is that I have Redshift installed and I'm on Lubuntu 21.04.
Regarding my graphics card and drivers, I hope that the output of lspci -nnk | grep -i vga -A3 [1] provides enough information:
00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 500 [8086:5a85] (rev 0b)
DeviceName: Onboard IGD
Subsystem: Intel Corporation HD Graphics 500 [8086:2212]
Kernel driver in use: i915
Any ideas?
