Memory usage after resume

Ask Fedora
1

Hi, guys. I Have a lenovo laptop with 8 gb ram (vram 2gb vega3 gpu and 6gb avaible) and newest version of kerne and Fedora 33 running on Wayland with GNONE, but something strange was going on. Laptop works fine after boot i have 5gb of free ram, no apps is running, and while session is active i have 5gb of free ram, when all apps is closed. After closing lid laptop going to suspend mode, but after resume i have 4.4 free ram.

Sometimes ago i have a bug with amdgpu, when laptop randomly cannot awake from suspend, but after update to kernel 5.9.11-200.fc33.x86_64 all works fine. But have this strange “memory leak”. What can i do for finding “memory hole”?

Check the column “available” instead of “free”:

free -m

Little comment: bug with new kernel is still present after long suspend, black screen when resume :crazy_face:

Use downgraded kernel 5.7.0-1.fc33.x86_64
