Hi there, it's my first post in this forum. I've searched for my question before creating a new topic. Actually, there is a topic that mentioned a problem after suspension. But the problem is different from mine. Because of that, I decide to open a new topic.
I've just installed Zorin 16 in my EliteDesk 805 G6 and it’s working great in general. But there is a problem when I resume after a suspension, the system is unusable, with problems in rending the screen, mouse and keyboard are almost unresponsive. The combination ALT+F2 works and I could execute a reboot. I’ve tried some workarounds, like increasing the swap file and checking if the video card driver installed is correct. As you can see in the output of commands bellow, the driver that Zorin 16 installed automatically is a amdgpu
My system is a AMD Ryzen 7, with two SSDs (one with Windows 11 and another with Zorin 16), 16 GB RAM, video card AMD Radeon RX550/550 Series (POLARIS12), version 4.6 (Compatibility Profile) Mesa 21.0.3.
