Ubuntu 18.04 mouse behaves weird after login

cw flag

When I start Ubuntu and before login the mouse behaves normally. After login the mouse behaves weird. I can move the mouse in just a tiny area after stopping the movement the mouse pulls to the middle of that small area. The keyboard behave (as far as I can see) normally. I did not take any specific actions, like installing or configuration software, before this weird behavior started.

What I tried: Login in as a different user makes no difference. Switching to another mouse makes no difference. Unplugging the mouse before login and plugging it in after does not make any difference.

I searched on Ask Ubuntu and the closest I came was: Ubuntu 18.04 desktop frozen after login (mouse doesn't move, keyboard unresponsive) The behavior here is quite different.

Try reinstalling the mouse driver.

Because I waited a log time, Ubuntu ask me to update. I did, but no difference. I waited longer, and was ask to Upgrade to 20.04. I did. Bu tno difference. I assume this upgrade to 20.04 was also a upgrade of the mouse driver.

And it is, in the GUI for me impossible to reinstall the mouser driver, because ... I can not use the mouse. By the way, the mouse is correctly installed, because before login, I can normally use it. After login the use of the mouse get corrupted.

Do ```sudo do-release-upgrade``` to upgrade. if not try upgrading again. The newer kernel should have better patches for your system.

Rebooting again solved the problem. So it was indeed the update /upgrade. Comments given in this thread helped my to give a direction to the solution. I would like to marked this as solved. I could answer and solve my own question. But I feel then the value of the contributes who helped me is lost.

The update and upgrade to 20.04 and an extra reboot solved the problem. Thanks to all who contribute to come to this solution.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
