I applied the attached patch, modified from wvengen's patch in comment #112 and built against xserver-xorg-core 2:1.17.1-0ubuntu3 on Ubuntu 15.04.
This fixes the scaling behaviour on an external monitor and my cursor is now able to move within the bounds of the scaled monitor. Compared to the version against which wvengen's patch was applied, there is some additional logic in the file to be patched concerning rotation. I do not know if this patch handles rotated cases properly. ** Patch added: "randr_scaling_ubuntu1504.patch" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/883319/+attachment/4399679/+files/randr_scaling_ubuntu1504.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/883319 Title: xrandr --scale restricts area in which mouse moves To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/883319/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
