I forgot to say that this problem is only with the external mouse. With the touch pad, i have no issue.
I have an RTX 2060 Max-q in my notebook with Nvidia driver installed but it is deactivated as on demand. But even if I enable this card, it has no effect. I believe that because of the fractional scaling, the reading of the input device gets somehow mixed up. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1902436 Title: Mouse slow in fractional scaling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1902436/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
