Debian's blank screen after suspending on Thinkpad T495

tl;dr: sudo apt install firmware-amd-graphics

After working on a huge legacy project that demanded a beefy desktop at the company I can finally work from my laptop through Virtual Machines. These are the specs for it:

CPU: AMD Ryzen 7 PRO 3700U
RAM: 40GB
DISK: 1TB NVMe SSD

It’s not news that I love NixOS and run it on all my devices. However, for some reason I can’t really explain or reason upon, I prefer to run Debian on my laptop. I went ahead and installed it but… after letting it sit for a few minutes I faced an issue: resuming from Suspend gave me a blank screen with no option out of it other than force rebooting.

After a long research and multiple attempts testing some GRUB_CMDLINE_LINUX1 arguments, I finally found the solution:

sudo apt install firmware-amd-graphics

  1. Did you know that setting splash on GRUB_CMDLINE_LINUX_DEFAULT gives you a cute splash screen instead of a tty asking for your password to unlock your encrypted partition? ↩︎
