xrandr --scale restricts area in which mouse moves
|||X.Org X server||
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.
- 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
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
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...
