If the problem gets worse over time then it might be memory related. Please run:
ps auxw | grep gnome-shell and tell us what you see when it is (a) fast and (b) slow. If that's the problem then it is likely an extension is to blame. So make sure you have uninstalled ALL of them, at least temporarily as a test. ** Tags added: nvidia -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1869568 Title: Unlock takes a long time Status in gnome-shell package in Ubuntu: Incomplete Bug description: I searched and found related bugs #1774188 and #1847566, but one of those is against 19.04, which is end-of-support, and the other was abandoned with no feedback from the OP. So, let's try again. When unlocking my screen, it takes progressively longer to unlock. After a fresh restart, it's pretty quick. After about a day, it takes about a second. After a longer period, it takes up to 5 seconds. When I press Enter at the lock screen to get to the password entry, the "wipe" effect commonly stalls as it gets near the top of the screen; not sure if this is related. After correctly entering my password, it takes several seconds before my desktop is visible. It's _there_, because moving the mouse around changes the mouse pointer according to what's under it (e.g. it turns into an I-bar on the Firefox search/address box and a finger icon on a link). It just takes several seconds to actually draw the screen.
