I have been using Fedora (39 and 40) over the past few months and have been experiencing a recurring issue. On my system (HP Elitebook 845 G9), it seems that whenever I leave the system idle for a significant amount of time (and presumably go into sleep mode) the entire desktop experience is extremely sluggish after wake from sleep. This is always solved with a restart. This impacts every single application, and affects app startup times, response times with UI elements (dragging windows around, minimizing, opening context windows, etc.), and results in a very sluggish browsing experience with Firefox (which is typically the only program open in the foreground at any given time). As I’m typing this, I even experience lag in the words showing up on screen. I’ve made sure AMD P-State and EPP have been enabled following this guide and I’ve enabled fingerprint support by modifying the login to allow a second step if the enter key is pressed, but other than that, I haven’t made any odd modifications to my system. I setup my install using LVM during initial setup if this changes anything as well.
To describe the issue simply, using my laptop in this state feels like I’m running an Intel Atom CPU from 10 years ago. It gets to the point where the laptop is almost unusable, despite the fact that CPU usage never goes above 30% in daily use (even now while I’m experiencing massive lag, the CPU is sitting at 15%. I’m also sitting at 7.5/30.7 GB memory use, etc. Here is the output of top:

Mesa is updated to the latest version, as is my BIOS and kernel.

Thank you for reading this and I appreciate your support! I wouldn’t be surprised if the cause was something simple and silly…
(Edit: I should probably add that I don’t believe the issue is hardware related - I bought this laptop new and when running Windows on dual boot it has no problems with idle and stays at max performance. I have tried all AMD EPP profiles (balanced, powersave, maxperf) to no avail.)
