I too can confirm that scaling doesn't work with radeon. On a laptop with intel driver, the following works fine, except the mouse pointer is confined to the mode area, but I believe that is a known xorg-server bug: xrandr --fb 1920x1080 --output eDP1 --mode 1600x900 --scale-from 1920x1080
The same command, adapted to the radeon output device doesn't work. Same software configuration (xorg-1.15.99.903, libdrm-git, mesa-git, xf86 -video-ati-git, various kernel versions (at the moment 3.15.2)). Screen rotation does work, though. -- 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/883319 Title: xrandr --scale restricts area in which mouse moves Status in X.Org X server: Incomplete Status in “xorg-server” package in Ubuntu: Fix Released Status in “xorg-server” source package in Precise: Fix Released Status in “xorg-server” source package in Quantal: Fix Released Status in “xorg-server” source package in Raring: Fix Released Bug description: 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 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 To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/883319/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
