@vanvugt 1. By lagging I mean that the cursor doesn't move in a continuous motion. Rather it shows up and stays in spots along the line I move it. Kind of like a video shot at a low framerate but not as consistent. As explained in my original post, it's only a graphical glitch. (e.g: When I try to move the mouse pointer over the left menu in settings, the boxes become highlighted even though the pointer is lagging behind.)
2. The problem persists when using Ubuntu on Wayland after selecting 'intel' mode in 'nVidia X Server settings'. Wayland is unavailable when using nVidia drivers (I think because they only support Xorg?). Notably, there is no issue on the lock screen using either driver. 3. During a quick test with the mate desktop, I experienced no issues. Other things that might be useful: I already stated that connecting a second monitor makes things better sometimes. I have now concluded that both connecting and disconnecting can usually fix things, at least temporarily. I have also experienced logging in without issues a few times. Even then, I experience some sporadic lag, but it's quite managable. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1877686 Title: Mouse lags since 20.04 update Status in xorg-server package in Ubuntu: Incomplete Bug description: After installing ubuntu 20.04, I have an issue with my mouse pointer lagging a lot. It happens on my trackpad, physical mouse, wacom tablet, and trackpoint. It's only a graphical issue (ie: The underlying whatever is actually moving. The visible pointer just isn't). Other mouse moving related actions do not exhibit the same behaviour. Window dragging is smooth. Applications that use custom mouse pointers, such as krita, work smoothly. The issue persists both on nVidia graphics and intel integrated graphics. I am using a lenovo thinkpad p50. The issue persists constantly when I am using the in built laptop screen. However, when I connect a second monitor, it only happens occasionally. I installed ubuntu 20.04 from a usb drive, keeping my home partition from 18.04.
