In the login screen, press the F1 key and change to a different window manager before loging in. For example, min-jwm or min-icewm (or something else). If it logs in properly without the same error message we know that the Window manager is the one responsible for the high resource use OR a startup command in ~/.desktop-session/startup.
So, the order of things to do to find out what the problem may be is:
0. Log in to a desktop session without desktop icons or autostart programs using a different window manager to your default (Any min-<window-manager> session, for example minimal-jwm or minimal-fluxbox).
Result A: Logged in OK -> The System is OK. Proceed to step 1.
Result B: Same result -> The issue may be Xorg relatd or something else. We will explore this if needed.
1. Switch to a session with program autostart different with same window manager as step 0 (example jwm or fluxbox) using Other Desktops menu or logging out and logging in.
Result A: Switched OK. The problem is NOT related to autostart programs. Proceed to step 2.
Result B: Terrible performance and error -> The issue may be related to a program that is trying to start from ~/desktop-session/startup. Go back to step o that worked and edit the startup file and comment all startup commands. Go back to test 1. If it works, then you can start exploring one command at a time from startup until you find the culprit.
2. Switch to a session with Desktop icons with same window manager as step 1 (example, rox-fluxbox, spacefm-jwm).
Result A: Switched OK. The problem is NOT related to the file manager that manages the desktop. Proceed to step 3.
Result B: Terrible performance and error -> The issue may be related to the file manager that manages the desktop icons. Take not of which it is and try Step 2 again with same window manager but different Desktop icon handler. If that also fails, then the problem is the desktop-session program. We will explore this if it comes up.
3. Switch to the original window manager you had as default, but without a desktop icon manager (example: if your default was rox-icewm, you switch to the simple icewm session instead).
Result A: Everything OK. You can now test the default session and see if it related to the desktop icon manager ONLY for your default window manager.
Result B: Shit gets loose. The window manager has a problem and may need to be reset and even reinstalled. Go back to a working desktop session and change the ~/.icewm (if this is the window manager that is giving problems) to ~/.icewm-backup with the command:
mv ~/.icewm ~/.icewm-backup
cp /etc/skel/.icewm ~/.icewmThis will restore the icewm configuration to the default. Try step 3 again and if it fails again, try reinstalling the window manager
sudo apt install --reinstall icewm
