Ghost Mouse coursor images on multiple monitor setup

[the Goat]

I'm using Ubuntu 9.04 beta. I have three monitors (two nvidia 7800GT graphics cards) set up with Xinerama spanning one desktop acrost all three monitors. I am using the ubuntu package nvidia binary driver (version 180).

When I drag the mouse pointer from one monitor to the next monitor it leave a "ghost image" of the mouse pointer on the first monitor.

So I always have three mouse pointers. One pointer on each screen. Only one moves with the mouse. Also if I take a screen shot <shift><pntScn> only the one "real" mouse pointer shows up.

I tried disabling hardware mouse acceleration in xorg.conf. That caused the mouse pointer to leave a courted ghost trail (the background was not correctly drawn after I moved the mouse over a given location). But that only happened on the two auxiliary monitors. The Mouse worked fine on the primary monitor.

Got about the same with nvidia 9800GX2 and dual monitor. I think it does not come from the nvidia driver, I use the 180.44, as I did on Ubuntu 8.10 where there was no problem.

I have that "ghost" pointers, but it's not the only problem I have ; when I start a program, until it is completely started, the mouse can't go on the second screen. It stays on the left screen and if I try to put it on the right screen, the pointer comes back at the left of the left screen.
I tryed to take a screenshot and on the screenshot we can see only the real pointer.

I have the same issue after upgrading to Jaunty. Three screens running on two nvidia 7800GTs with the nvidia driver 180.44. I get exactly the same behavior with respect to the ghost images of the pointer.

[mattm591 (mattm591)]

I can confirm this issue also.

Just upgarded from 8.10 where the issue wasn't present to 9.04.

I have an nvidia card and am using the version 180 propietary driver as installed by Ubuntu on 8.10

My dual monitors are set to have a different desktop on each.

I can also confirm this.

No "ghost" pointer in 8.10 using nvidia driver 180.44 on a 7600GS, but after upgrade to 9.04 yesterday they exists.

Running a dual screen setup with separate X screens, no Xinerama or TwinView.

I can confirm this behavior as well. No problems at all with 8.10 fully patched, but the upgrade caused the behavior described. I noticed that my xorg was modified by the upgrade to comment out the mouse and keyboard sections in favor of HAL.

Same problems as @m3ta-x (ghost pointer and unable to get mouse to second screen) with Ubuntu 9.04 and ATI Linux Driver, while in 8.10 all worked ok.

[Colin Norris (sirrontm)]

I'm on 9.04 amd64 now, upgraded from 8.10 using Update Manager. I'm using version 180 of the Nvidia driver with my GTX 260. I've got two monitors configured as separate X screens, and if I move the mouse pointer from one screen to the other it always leaves a ghost behind.

[Shimmy (ramsom)]

I can confirm this, after upgrade from 8.10 to 9.04 using the fglrx driver.

[gmh04 (gmh04)]

I can confirm this also upgrading from 8.10 to 9.04 using the fglrx driver.

This is the same as 364983 ( Xorg mouse artifacts when moving between displays using ATI's driver).

[sperlyjinx (jgbaum)]

It is not the same bug, as it is also happening when using Nvidia's driver.

I tried a new installation, not an upgrade. And the problem is still the same.

[malder (malder-gmx)]

I have a new installation of Ubuntu 9.04, 3 monitors, 2 nvidia graphic cards, using nvidia driver version 180. Same effect here. This bug is really new. I never had similar problems in previous versions.

[Bastien Scher (bastien0705)]

I have this bug too, with NVidia proprietary driver 180.44 downloaded from their website.

I also have a bug with Xinerama and my laptop's touchpad, appeared when I upgraded to 9.04. Maybe is it linked ?

[m3ta-x (ubuntu-addict)]

Bastien Scher, no it does not come from your Nvidia drivers. It affects every materials, ATI and Intel too.

[Marius B. Kotsbak (mariusko)]

Same as https://bugs.launchpad.net/bugs/357901 (which has a solution)?

[gmh04 (gmh04)]

I've applied the patch and it works!

Great thanks!

[m3ta-x (ubuntu-addict)]

It works a half. The ghost cursor is ok now for me. But I still have the problem that when I launch an application, my cursor can't go on the other screen

[Marius B. Kotsbak (mariusko)]

That is maybe another bug. Similar to this one:?

[m3ta-x (ubuntu-addict)]

Well, not really. When I launch an application, my cursor can't quit the left screen.
If i try to move the cursor to the right screen while the application is launching, it jumps at the left of the left screen. But, the cursor acts on the right screen, even if it's still visible and moving on the left screen.
Everything comes back to normality when the application is completely loaded and ready to use.

I don't speak english very well so if you don't understand, tell me :)

[Bastien Scher (bastien0705)]

I have about the same bug as m3ta-x.
It can happen on left screen as on right screen.

Most of the time, I have Firefox launched in the right screen (entirely), and the cursor is in the left one. Suddendly I can't move the mouse to the right screen (it goes to the left border of the left one). But I noticed that I could move it to the title bar of Firefox. When I try to move it down, the cursor teleport itself to the left screen. :o
It happens even if Firefox is loaded, and not only with Firefox (sometimes with aMSN, which is in the left screen).

As m3ta-x, I'm not English-native, so sorry if I made mistakes. ^^

[dododge (dododge)]

I've also seen the same issue as m3ta-x. While an application is starting up, mouse movement between screens (or at least the location of the visual pointer) goes haywire. Once the application is ready, it goes back to normal. Of note is that I saw this behavior while using the xfce desktop, but not (so far) while using the lxde desktop. Granted, I just upgraded to 9.04 about an hour ago so maybe the cause just hasn't triggered yet on lxde.

[m3ta-x (ubuntu-addict)]

I confirm that this bug does not affect LXDE.
Why..? I don't know!
