Hello, sorry for late reply. I forgot about this and never got notification of your replies.
Anyway, it appears this has been reported in bug #1565846 and has nothing to do with BIOS, but is a known GNOME issue as mentioned in that bug. I'll be soon upgrading to 16.04 and can then confirm if that fixed the issue, as bug #1565846 suggests. -- 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/1523086 Title: Ubuntu 15.10: GNOME Terminal window loses mouse cursor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1523086/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
