I have now done further testing and can confirm that this is more than just upgrade issue.
I have done the following tests: A) Fresh 19.04 Desktop Install A.1) Boot - Ubuntu 19.04 Desktop CD-ROM image via USB - Mouse / Cursor ok A.2) Do clean disk install of 19.04 Desktop (Minimal Install Option selected) & Reboot. On reboot - Mouse / Curser ok A.3) Disable Wayland and reboot - Mouse / Cursor ok A.4) Do in place upgrade to 19.10 & reboot - Mouse / Cursor - Stopped Working B) Attempt Fresh 19.10 Desktop Install B.1) Boot - Ubuntu 19.10 Desktop CD-ROM image via USB - Mouse / Cursor not visible So I have unable to proceed with clean 19.10 install as there was no mouse cursor visible. So problem is to upgrade related but a general one for 19.10 release. Both my testing and Paul Bundt's was on server boxes: Dell Server with Matrox G200 and Lenovo x3650 with Matrox G200. -- 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/1851340 Title: Ubuntu 19.10 upgrade results in invisible mouse cursor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1851340/+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
