XORG - xrandr scale traps mouse

[Simon]

Xrandr reports this;

Screen 0: minimum 320 x 200, current 1360 x 768, maximum 2720 x 1536
DFP1 disconnected (normal left inverted right x axis y axis)
DFP2 disconnected (normal left inverted right x axis y axis)
CRT1 disconnected (normal left inverted right x axis y axis)
CRT2 connected 1360x768+0+0 (normal left inverted right x axis y axis) 16mm x 9mm
   1360x768       60.0*+
   1280x768       60.0  
   1280x720       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9

When I use this command for my virtual 2720x1536 screen;
$ xrandr --output CRT2 --scale 2x2

It traps the mouse in the upper left quad of the screen and is restricted. I did some research on this minor issue. I found most solutions point at the xserver needing to be "upgraded" but I have the latest and greatest according to apt-get. Some solutions suggested rolling back to an earlier version.
I currently have;
xrandr program version 1.3.5
Server reports RandR version 1.3

Any clues on how to upgrade xrandr or will that just cause more issues?

Try:

xrandr --output CRT2 --panning 2720x1536 --scale 2x2

No same results, but thanks for the support.


Sorry.

What version of Kubuntu/xorg are you using? Mine shows "Server reports xrandr 1.4"

[oshunluvr]

Tested it here and got jumbled video, but the mouse traps correctly. I have dual monitors using twinview so the command scrambled the video, but the mouse cursor went over the whole screen and was quite a bit smaller than usual. It appears to have worked - at least as far as the mouse goes.

Kubuntu 12.04 using the kdm manager. My xrandr is 1.3.5 but I understand there is 1.4.0 and 1.4.1 available. No luck in finding a download.

According to my package manager I have;

xorg (1:7.6+12ubuntu2) precise-proposed; urgency=low
x11-xserver-utils (7.6+3) unstable; urgency=low
xserver-xorg-video-ati (1:6.14.99~git20111219.aacbd629-0ubuntu2) precise; urgency=low

My GPU is a 1 GB ATI Radeon HD 5450, I know this is an Xrandr problem one only need to search "Xrandr Mouse Restricted" and you will see and read all sorts of info about patching, downgrading or upgrading. I am just looking for the clear path to take.

Thanks to everyone for their attention on this minor issue.

Edit: Just found this --> http://cgit.freedesktop.org/xorg/app/xrandr/
Anygood? Can I eat this? Should I eat this?

Don't mean to be a nuisance, but so far this has lead me to one dead end after another...

I downloaded both compressed files for 1.4.0 and 1.4.1 ... I am not PC geeky enough to know how to use them. Because they are C source and not the compiled binaries, I ran the autogen bash and came up with an error message telling me not to mess with stuff that is not in my field of expertise.

This topic (https://bbs.archlinux.org/viewtopic.php?id=118999) came to my attention and was started on May 2011 and ran to Oct 2012 without a real solution in sight.
This one (http://forums.linuxmint.com/viewtopi...337f793ef4c3f5) for Mint began Dec 2011 and ended March 2012 with the last poster asking how to apply patches.
Red Hat Bugzilla seems to ignore it all together: (https://bugzilla.redhat.com/show_bug.cgi?id=655212)

Like I said, this is not very important to me, but it seems to be linked to several unanswered questions. I am still seeking the answer.

Not much new here.

But I refreshed my xorg edgers ppa, reinstalled xorg, and made certain everything was updated. Still Xrandr reports the same as before. Highest version available is 1.3.5. I found 1.4.1 for compiler. Currently looking into what else I need to compile the source. "Dammit Jim! I am a doctor not a computer programmer!"

Most of these modes are not supported by my monitor. The only reason I use Virtual mode is to take higher resolution screen shots. But mouse being able to reach all sections of the screen would be nice too. I also toyed with the notion that the mouse is not set up correctly in the xorg.conf?

I am no xorg expert but I don't see anything locking my mouse into the box...
I suppose I can play with getting 1.4.1 on my system next weekend.

I had a minor break through on this issue...

I shut down my AMD Catalyst Control Server, by removing the driver using Addition Drivers option. I don't see this as a victory, it just tell me my "proprietary" driver is most likely to blame. For the time being when I need a bigger (higher resolution) snapshot without the mouse getting trapped, I just need to temporarily knock out the AMD drivers. If any driver guru has a way to turn the drivers on and off without the install/uninstall I would love the help.

Oh BTW...
This is my most current and up to date xorg.conf
