On version 1.4.2 of xorg-server, in an Xdmx session, the mouse flies to the top left corner of the screen as soon as you touch the mouse. I didn't find a way to "un-stuck" it. Noteworthy fact: I can start an Xdmx session from one host like this Xdmx :1 -display localhost:0.0 -display:host2:0.0 Say I have two computers, this works on both of them, even of the xorg server version is different (that means: Xdmx starts up correctly). But, the problem occurs only if the command is ran on the host with version 1.4.2. If I start the same command on host2 with an older xorg version, the problem doesn't occur. The order of the -display parameters also doesn't seem to matter. I can even reproduce this locally on host1.
Any chance on this being hal/evdev problem ? Does mouse device gets any input ? Perhaps you should attach your xorg log.

I once experienced this problem when I accidently used the wrong mouse protocol for my mouse. Looking at your xorg logfile it seems like you chose "auto" as protocol for your mouse. Maybe putting a specific mouse-protocol into your xorg.conf fixes this problem?

I tried ImPS/2 and Microsoft, didn't solve the problem.
Please post your `emerge --info' too.

xorg-server-1.4.2 is no longer supported. Please upgrade to 1.5.3-r5. Thanks
I did. See #265544.
This happens with 1.5.3-r6 too, after having applied the patch from #265544 Btw. this also happens on a single monitor xinerama setup. To reproduce: xhost + (make sure your X is listening for TCP) xinit /usr/bin/xterm -- /usr/bin/Xdmx :1 -ac -display localhost:0.0 +xinerama
I'm guessing this patch: xorg-server (2:1.6.0-0ubuntu11) jaunty; urgency=low * Add 175_set_pointer_screen_in_xtestfakeinput.patch: Fixes issue when using Vino, mouse cursor can get stuck in the upper left corner of the screen. The POINTER_SCREEN flag must be set explicitly for XTest core events to avoid out-of-range events when the lastSlave was an SD with an explicit axis range. Device events sent through XTest don't need this flag, they are expected to be in the valuator range of the device anyway. (LP: #337926) Will fix it.

Could you try with xorg-server 1.6 ? Thanks
Hi Remi, I have just tried 1.6.1.901-r3. My feeling is that that version does indeed fix the Xdmx mouse pointer issue, but that release has issues with geode. (I already made an ebuild for xf86-video-geode-2.11.2) but X keeps segfaulting with the geode driver in function xf86RandR12CreateScreenResources. (fbdev works fine, but I can't get xinerama to work on that).
This describes what I am currently experiencing https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/348553
about comment 15: it was not geode that makes it segfault, it is xinerama itself. Just enabling it causes X to segfault
Apparently, the segfault in starting X.org 1.6 with xinerama enabled has something todo with this patch: http://osdir.com/ml/fedora-extras-commits/2009-04/msg04653.html The geode driver apparently confuses X when it comes to whether Xrandr is enabled. My guess is that on a non-geode system 1.6 should start fine with xinerama. Now I'll start testing whether this bug is actually solved in 1.6
If I understand, the Xdmx bug is solved. Feel free to open another bug for the geode issue if you want it looked at by Gentoo devs or feel free to open a bug in FreeDesktop's bugzilla. Thanks
