Just upgraded my system and the problem seems to be solved. But I'm a bit confused regarding the package versions. Is there a -1ubuntu2 and -1ubuntu2.0? Because later is what is installed now:
$ apt-cache policy xserver-xorg-core xserver-xorg-core: Installed: 2:1.18.3-1ubuntu2.0 And the log shows that it was upgraded: 2016-05-17 10:08:54 configure xserver-xorg-core:amd64 2:1.18.3-1ubuntu2.0 <none> 2016-05-17 10:08:54 status unpacked xserver-xorg-core:amd64 2:1.18.3-1ubuntu2.0 2016-05-17 10:08:54 status half-configured xserver-xorg-core:amd64 2:1.18.3-1ubuntu2.0 2016-05-17 10:08:54 status installed xserver-xorg-core:amd64 2:1.18.3-1ubuntu2.0 Either way, I'm not affected by this issue anymore. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1580123 Title: xrandr --scale (again) confines mouse to native solution Status in xorg-server package in Ubuntu: Triaged Bug description: This might be a regression where the original issue is: https://bugs.launchpad.net/xorg-server/+bug/883319 It can be easily reproduced by doing something like: xrandr --output DP1 --scale 1.25x1.25 The mouse will be still constrained to the native solution (aka you can't move the mouse outside a box of whatever DP1 had as resolution before. $ lsb_release -rd Description: Ubuntu 16.04 LTS Release: 16.04 $ xrandr --version xrandr program version 1.5.0 Server reports RandR version 1.5 $ apt-cache policy xserver-xorg-core xserver-xorg-core: Installed: 2:1.18.3-1ubuntu2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1580123/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
