You have been subscribed to a public bug: I have relatively recently loaded Ubuntu 20.04 to dual-boot on a Packard Bell with Windows 10 Home 64-bit already installed. The mouse-pointer moves and clicks perfectly when the PC has a single-monitor. However, for work as a developer, I should like to use a dual-monitor setup.
The problem I have is, if I plug in to the PC tower a second monitor and follow the steps to Connect Another Monitor To My Computer (https://help.ubuntu.com/stable/ubuntu-help/display-dual-monitors.html), and after I confirm "join Display", the mouse-pointer jumps about and a second stationary mouse-pointer appears in the bottom right of my primary screen. This behaviour stops immediately I confirm "Single Display", but now the second screen is now turned blank. $ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ USB Wired Keyboard Consumer Control id=12 [slave pointer (2)] ⎜ ↳ PixArt USB Optical Mouse id=13 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ USB Wired Keyboard id=10 [slave keyboard (3)] ↳ USB Wired Keyboard System Control id=11 [slave keyboard (3)] ↳ USB Wired Keyboard Consumer Control id=14 [slave keyboard (3)] $ sudo dmidecode -t 1 # dmidecode 3.2 Getting SMBIOS data from sysfs.

I do need a dual-monitor set p for work. Currently, I can use Windows10 with dual-monitors, on the same machine, without a glitch. ** Affects: gpm (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment -- Multiple-monitor Set Up Makes Mouse-pointer Jump About in 20.04 https://bugs.launchpad.net/bugs/1884536 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gpm in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
