Mouse pointer gets stuck on the rightmost X screen

[vivia]

Binary package hint: xorg

Hello,

I am having the bug described in http://bugs.freedesktop.org/show_bug.cgi?id=12145 .

I am trying to use a dual-monitor setup on a laptop. As soon as I move the mouse pointer to the rightmost screen, I can only take it back to the leftmost one using the USB mouse. The touchpad doesn't work, I really need to have my USB mouse connected.

I don't understand the internals of Xorg well enough, but I think the bug report means that there is a patch released. I would like to see this packaged in Karmic.

Thank you.

I was playing around with a second screen yesterday and experienced the exact same problem. However, it isn't specific to the 'right most' screen, it's whatever the second screen is, independent of relative positions. I configured the second screen with the ATI Control Center app that comes with the fglrx drivers, and the bug showed up with separate X screens, or with xinerama, but not with one unified screen (which makes sense). I also tried configuring the screens with the gnome display properties app, but got the same results.

I can also verify that hooking up a usb mouse allows you to move the pointer back to the main screen.

Because my apport-collect was run without the second screen attached, I've manually added one of the dual-head xorg.confs that was causing me the problem.

[Aarons-freedesktop (aarons-freedesktop)]

With a dual-head setup with separate screens (with or without xinerama) the pointer when controlled with the ALPS trackpad on my laptop can move to the second screen, but not back to the first screen. The cursor can be moved back to the first screen with a USB mouse.

This downstream bug has more information:

https://bugs.launchpad.net/bugs/444154

that bug was originally filed against the nvidia driver, but I have ATI, so problem is either in the server or input driver, I assume.

[aarons (aarons-ubuntu)]

I noticed that this bug is within the nvidia graphics driver, but I have ATI graphics, so I think the bug is in the xserver.

[Hassanakevazir (hassanakevazir)]

Same issue here, using a Dell inspiron 1520. After updating the nvidia driver from 180.00 to 195.22 this issue persisted, I cannot move the pointer from the the screen on the right back to the left screen without attaching a USB mouse to my laptop.

[mrej (mrej-junk)]

Exact same behavior on Asus F9s, after my upgrade to Karmic.

[joecarter (joe-carter)]

Same issue with an Asus 4350 (ATI). Interestingly I could get my mouse to the other screen with the menus if I created a file, kicked off an editor and dragged it right. At that point the mouse was working properly. Dragging was partially broken as it would only drag to halfway across the problem screen. Enabling/disabling one screen fixed the problem.

[Jean (alessandro-lai85)]

Same bug on Toshiba Satellite Pro P100, nVIdia 7600. It seems to affect both ATI and nVidia, maybe is X11 or Gnome's fault.

[Hassanakevazir (hassanakevazir)]

https://bugs.freedesktop.org/show_bug.cgi?id=25182 upstream (not my report)

[Jean (alessandro-lai85)]

So it seems that the bug is on just when the mouse is controlled by a touchpad, and not when a usb mouse is in use?

[Jean (alessandro-lai85)]

I'm also getting full-system freeze after enabling the two separated x screens, just after the automatic logon. That's really weird.

[themuddler (mike-udall)]

Still a problem on Lucid RC. Could this be fixed before the final release? Any ideas whether there is work in progress upstream?

[Dav Clark (davclark)]

Affects me on a Lenovo ThinkPad T510 with the nvidia discrete graphics chip (NVS 3100M / GT 218 core). Interestingly, the trackpoint cursor control gets me across the screen boundary either direction, while the touchpad only works in one direction. (i.e., the trackpoint yeilds the same behavior as a USB mouse - full functionality)

[Sree Harsha Totakura (sriharsha-totakura)]

From the following links, I suspect the bug to be in xserver-xorg-input-synaptics package.

[Peter Hutterer (peter-hutterer)]

Server bug, affects all absolute devices.

Problem is simply that when we scale an axis range into [0..screen width], the latter is actually one past the highest possible coordinate and triggers the screen crossing. 0 is still part of the screen and does not trigger the screen cross. Hence you can only change screens to the right/bottom.

    input: change pointer screen crossing behaviour for multiple ScreenRecs

This is a large change, so I don't expect it to be back-ported to 1.11.
