*** This bug is a duplicate of bug 389519 *** https://bugs.launchpad.net/bugs/389519 I agree that it would be difficult to fix the mouse grab issue within X. I find that the only issue is when I click the mouse, so I don't click the mouse. I find the edge first, without the mouse clicked, then I click the mouse and move away from the edge. It would be nice to handle the action directly, but again, I don't think X provides any notification to the window when it is entered while the mouse is attached to another window (the clicked in window). Anyhow, I tweaked the code further. However, I left in 'modes' for those that want that behavior, but I changed the default (no mode specified) to block on all edges. I also fixed the need to specify a void that doesn't exactly match the offscreen size. It is still possible to sneak the mouse past the edge, but it is much less likely now, and the simply solution is to just drag the mouse horizontal or vertically (depending on the void orientation) and the mouse will come back (not actually stuck, just lost...). Making the void bigger in the negative space may help too (I didn't try it because I found it very difficult to lose the mouse anymore). I added a makefile, just type 'make' to build (or 'make debug' if you want more verbose output from the executable...). I think there is already a mouse capture project under SourceForge, and that may provide a more robust solution, but I stuck with XCreateMouseVoid because it is so small...and I'm providing my tweaks because it appears to work better on my machine now... ** Attachment added: XCreateMouseVoid.tar.gz https://bugs.launchpad.net/ubuntu/+source/libxrandr/+bug/373367/+attachment/1968593/+files/XCreateMouseVoid.tar.gz -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxrandr in Ubuntu. https://bugs.launchpad.net/bugs/373367 Title: Pointer goes offscreen on non-rectangular dual-head ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

@Jeffery To: I don't know enough about X programming to fix the menu issue (and my limited knowledge suggests that it's not possible for an application like XCreateMouseVoid - it really does not receive events when other window does active mouse grab; one would have to use XTest, I imagine (and I remember seeing an app doing exactly this to fix the same issue that's being discussed here (but it was KDE-dependent, so I was too lazy to try it))). As for the 'mouse stuck at the edge' problem: try creating a largish void with the top-left corner far away in the negative coordinates; for best results - with the _center_ in the negative coordinates; i.e. if your invisible zone is from 0,0 to 1024,400 - do smth like XCreateMouseVoid -1100 -500 2124 900 That should make it impossible for the mouse to enter the zone where it's being pushed away from the screen (usuccessfully); just '-1 -1' isn't enough as the first event seen by XCreateMouseVoid may be well inside the window due to mouse acceleration and/or system load. -- Pointer goes offscreen on non-rectangular dual-head https://bugs.launchpad.net/bugs/373367 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxrandr in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

@Alexey A. Kiritchun: If I position the blank window at x=0, y=0 (my void is in the top-left corner of the virtual desktop), I can still move my mouse cursor between the window and the screen edge (into the void). If I position the window at x=-1, y=-1, the mouse cursor gets stuck at the edge and I need to kill the program to release the cursor. Can this be fixed? Also, if I click open a menu (the main menu, any application or context menu), my cursor can then enter the void. (Perhaps the window stops getting events if a menu is open?)

Slightly reworked nZain's XCreateMouseVoid.c: no more 'modes', just 'edge resistance' all around; also fixes the slightly annoying mouse jumping. For best results create a window slightly larger than 'void', like this: +++ |screen1 |screen2 | | | | | ++-+ ++XCreateMouseVoid | | | +---+ This should disallow mouse 'sliding under' the void.

Compiz has a plugin that can prevent windows from getting offscreen. It does not restrict the cursor though, and I don't know about desktop icon placement. Activate the Put window plugin, go to Misc. Options and enable Avoid Offscreen. It would be nice if this functionality could be implemented for the cursor (and icons) too.

@Helge #27: That's not entirely accurate. The Avoid Offscreen option prevents the Put Window plugin for using the offscreen area. It only works when you use the Put command to move the window.

[Ubuntu-x-swat] [Bug 373367] Re: Pointer goes offscreen on non-rectangular dual-head
I have written a qt tray-icon based background app that basically keeps the mouse in the screen by polling for when its gone out of the screen, but this is a very suboptimal solution since it has to poll many times a second and eat cpu. It sometimes reaches 1% cpu even! And X is still getting the events, so it kind of bounces at the edges, not a great solution (but better than nothing). A proper solution would be to somehow get the driver or the X system involved, because we'd want to intercept these pointer events before they reach X or at least before it sends them on to client applications. If someone has information on where to start looking if I wanted to mess around with this at a higher level (X or driver or something) please let me know - I have the means, but I'm kind of lost in the architecture here.

I think this problem is more generic. I have an ATI x1400 using the radeon driver on Ubuntu Karmic and I see the same problem.Right screen is laptop 1920x1200. Left screen is 1280x1024 LCD.

If I place the screens so that they join at the top corner I can't see icons (and desktop applets) that are at the bottom. Vice versa if I join the screens at the bottom corner. The WM thinks I have a 1280x1200 desktop with a 1280x1024 fixed view. Further, if I unplug the external display, the WM continues to operate as if the display was attached and new applications are frequently launched on that display and I have no access to them.

You can avoid this problem by placing the left monitor at the top. Furthermore, you only need one void then. Is there any reason, why you require the left monitor vertically centered?

[Ubuntu-x-swat] [Bug 373367] Re: Pointer goes offscreen on non-rectangular dual-head
Why is this set as Wishlist? If the mouse pointer could be moved outside the display area on a single monitor, that's a clear bug. I don't see how this is different, except that it's more technically challenging. A suggestion for the fix: Make sure the physical displacement of the mouse pointer when moving from one screen to the other is minimal, based on the layout and resolutions specified in the GNOME display preferences. -- Pointer goes offscreen on non-rectangular dual-head https://bugs.launchpad.net/bugs/373367 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxrandr in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 373367] Re: Pointer goes offscreen on non-rectangular dual-head
Same problem with my ATI card on Karmic, especially annoying since my desktop has the smaller screen (of 2) on the left side, and any icons that are automatically placed on the desktop will be placed in the 'virtual desktop void' on top of the screen, where I can't see them. So it's not just the mouse cursor being able to go there, but also desktop icons (I think the same also goes for menus and such). Would be nice for xorg/ubuntu's multi-head support if this got fixed :) -- Pointer goes offscreen on non-rectangular dual-head https://bugs.launchpad.net/bugs/373367 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxrandr in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 373367] Re: Pointer goes offscreen on non-rectangular dual-head
** Description changed: Binary package hint: xserver-xorg-video-intel On a non-rectangular multi-monitor layout (e.g. when using monitors with different resolutions) the mouse pointer can be positioned outside the areas displayed by the monitors. For example, with a configuration like Screen 0: minimum 320 x 200, current 3200 x 1200, maximum 3200 x 1200 VGA connected 1920x1200+1280+0 (normal left inverted right x axis y axis) 518mm x 324mm LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 304mm x 190mm The mouse pointer and some graphics part like dropdown menus can go in the non-visible area below LVDS. It is the same symptom as bug #119417. However this bug is for the Intel chipset.

[Ubuntu-x-swat] [Bug 373367] Re: Pointer goes offscreen on non-rectangular dual-head
I can confirm this problem on my Laptop+ext.VGA combination (Intel onboard graphic). Due to another problem with the notify-osd (positioned in the non- visible area of the virtual screen, see https://bugs.launchpad.net/bugs/367947), I'm currently forced to align the top of primary with the top of the secondary screen - resulting in a non-visible area at the bottom of the second screen. Hitting the window- list on the bottom gnome-panel is quite tricky with the mouse leaving the screen. Thus, I'd be really happy if the non-visible area is not accessible for the mouse. By converting affected mouse coordinates (vertical ones in my case) to the corresponding screen height (width for horizontal screen setups), this problem should be resolved. On screen change (from sc0 to sc1): mouse.curPos= (mouse.prevPos - sc0.visMin) / (sc0.visMax - sc0.visMin) * (sc1.visMax - sc1.visMin) + sc1.visMin where visMin and visMax is the visible area of the screen. best Patrick -- Pointer goes offscreen on non-rectangular dual-head https://bugs.launchpad.net/bugs/373367 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
