xrandr trap the mouse

[joe343]

Hi,

I have a Asus eeePC 1001PX with a maximum screen resolution of 1024x600. I tried using xrandr to scale the screen so I can fit a 1024x768 screen on my display using:

xrandr --output LVDS1 --mode 1024x600 --scale 1.00x1.28 --panning 1024x768

The problem is that the mouse is trapped by invisible boundaries at the bottom of the screen. It's like the display is now 1024x768 but the mouse is constrained in the original 1024x600 region - I cannot move the mouse to the bottom of the screen.

Do you have any idea why this is happening?

Thanks.

PS Running Mint 12 (gnome 3)

I found the same thing when running "xrandr --output LVDS1 --scale 1.25x1.28" to compress the screen in Mint 12 and Ubuntu 11.10. It worked in Mint 11...

I have a similar issue on LM 12 not with scaling but just setting the native resolution for my monitor. I used cvt to generate a modeline and then xrandr to add and switch to the new mode.

From glxinfo:

Code: Select all

 OpenGL renderer string: Mesa DRI Intel(R) 945G x86/MMX/SSE2

I looked around a bit and found that this graphics solution isn't terribly well supported on linux. Any ideas would be appreciated.

Slight update: I "fixed" this by downgrading. However the problem returned when I installed the latest stable synergy package from the project website, after downgrading that as well things returned to normal.

It's a bug: https://bugs.freedesktop.org/show_bug.cgi?id=39949

Has patch for a partial solution, only for panning but not for scaling: http://patchwork.freedesktop.org/patch/6488/

Arch users have the same problem: https://bbs.archlinux.org/viewtopic.php?id=118999

Hope the bug gets solved...

Edit:
There is a new patch: https://bugs.freedesktop.org/attachment.cgi?id=56408
Mint 12 LXDE has the same problem...

Hi,

How do you apply these patches?

Or, how can we switch to a newer or older xrandr version? 1.2 seems to have problems.

Thanks

I'll move my post elsewhere as this thread seems dead.
