For well over a week I've been first testing the success of panning for various combinations of gfxcard, monitor and fb size in servers prior to the changes resulting in this bug report and then same for installations to which I've updated using the 94929 patch applied by Tobias Klausmann in the openSUSE build-service. Initially the only recording I did of my testing I reported here. After while I began recording in the form of screenshots accompanied by the Xorg.#.log associated with each one. These are available for perusal at http://fm.no-ip.com/SS/Xorg/ . Among them is one instance of a scaling test, 1.2x1.2 applied to a 1440x900 screen. The largest fb size I tested was 3840x2400. The newest gfxchip used was a Intel 4000 series (G41). Others used are nv11, G84, rv200, rv250, rv380, i865G, i915G & i945G. The highest resolution used was 1920x1080. Total "success" pairs there currently is 31, of which 14 are pre-bug and 17 are server 1.16rc1. KDE3 & KDE4 dominate the DEs represented. A few are IceWM and Lxde.
The only outright failure so far was on i945G and 1.16rc1 on both openSUSE 13.1 & 13.2, but after another system/xorg updates round those inexplicable failures apparently solved themselves. Among the overwhelming number of "successes" are many instances of various forms of painting and mouse pointer trouble among the configurations with the largest panning areas that always goes away if panning is disabled. However, such problems are common to both old servers and DEs as well as current ones. The painting problems don't show up in any of the screenshots. Except for the comment 44 reported failure of xorg.conf* to produce expected results, WRT to bounds and sizes at least, the 94929 patch seems to be doing what it needs to do. -- 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: Confirmed 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
