Package with backported fix uploaded to precise-proposed for processing by the SRU team.
** Description changed: + SRU Request: + + [IMPACT] + A bug in the version of xorg-server in precise prevents users from scaling screen resolution. When attempting to do so, as was possible in Natty and earlier, and which is possible in Quantal+, the mouse pointer remains locked inside the old resolution. This prevents users of small screens such as netbooks from scaling to a greater screen resolution. + + [Test Case] + - On a netbook with intel chipset, such as a Dell Mini 9 or 10, scale the display by using the following command: + + xrandr --output LVDS1 --panning 1280x750 --scale 1.25x1.25 + + See if the mouse moves correctly to all screen extremities, and is not + confined by a transparent border at 1024x600 + + [Regression Potential] + This is fixed with a patch backported from the xorg-server version in Quantal. In theory it should just affect screen which are scaled and panned, which is uncommon. If so, the patch can be backed out. + + + + Original Bug Description: in kubuntu (and ubuntu) 11.04 i used to enlarge my laptop screen like so xrandr --output LVDS1 --scale 1.2x1.2 this worked fine: the desktop scaled to larger size correctly . After upgrading to 11.10, in kde the desktop still resizes correctly, but the movement of the mouse is restricted to an area equal to the screen size *before* issuing the scaling command. .. Ie let's say the mode is 1366x768 and I do xrandr --output LVDS1 --scale 1.2x1.2 the screen size changes to 1640x922 but the mouse moves in an area the size of 1366x768 in the top left of the screen and then 'hits a wall' preventing - it to move. I also tried ubuntu 11.10 with gnome: here the screen also + it to move. I also tried ubuntu 11.10 with gnome: here the screen also resizes, but I have the same issue with the mouse, and the extended area of the desktop is black... Some time ago there was a similar issue, which was resolved later. Now it seems to be back... jos@samsungsucks:~$ lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 jos@samsungsucks:~$ xrandr --version xrandr program version 1.3.5 Server reports RandR version 1.3 -- 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
