[Ubuntu-x-swat] [Bug 1073724] Re: Pointer barriers have gaps along the edge of the screen

2014-01-06 Thread Christopher M. Penalver
Tim, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p xorg-server REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is
already available, doing this on a release prior to the development one
would not be helpful.

Thank you for your understanding.

And a pointer barrier at the location labelled X, its possible to mouse
underneath the barrier from left to right and onto the second monitor.

Reproduced with xorg-x11-server-Xorg-1.12.0-2.fc17.x86_64

(Using GNOME 3 you can reproduce by setting up two monitors like this
with the primary monitor on the left - a pointer barrier will be set up
at position X to make the hot corner at the bottom left. Try mousing
along the bottom row of pixels on the left monitor. This leak is not
observed if the two monitors are the same size, indicating that the
pointer barrier is correctly positioned.)

Reproduced, but the conditions are narrow. The barrier must align with the edge 
of a monitor and the movement _vector_ must not overlap with the barrier.
e.g. if you're in that corner, moving by 1/1 will block, moving by 1/2 won't 
block.

Cause is that the fixes code that calculates whether a barrier is
blocking doesn't know about screen edges. So the picture the fixes code
sees for a movement a to b is

a X
 \X
  \
   b
Which is permitted since the movement goes just past the barrier. The RandR
code to clamp to monitors sees this picture:

 ++-+
 || |
 || |
 || |
 |  a | |
 +---\+ |
  \ |
  |b|
  +-+

Which too is allowed since the destination exists in RandR space. The two
operations are quite separated in the server, merging them is tricky.

As a workaround for now, I suggest either extending the barrier to the
bottom of the second monitor like this:

 ++-+
 || |
 || |
 || |
 |X |
 +X |
  X |
  X |
  X-+

or, alternatively, to create a horizontal barrier in that corner that shares
the same endpoint with the vertical one.

[Ubuntu-x-swat] [Bug 1073724] Re: Pointer barriers have gaps along the edge of the screen

2012-11-08 Thread Tim
here are excerpts from my IRC conversation with Jasper re this bug.

 darkxst, it's entirely possible that it will break it on monitor edges
 the barrier_find_nearest() function definately breaks on the monitor 
edges when using the unclamped values
 darkxst, I'm quite sure it will break BarrierNotify behavior, to be 
honest

 I know exactly what the issue is: since we're using the unclamped 
positions, they're not clamped to the screen edges
 if I hit the top edge I the screen it almost always slides past

 darkxst, we have three pieces of information: where the mouse came 
from, where the mouse is going to unclamped to the screen edges, where the 
mouse is going to clamped to the screen edges
 darkxst, between those three it should be possible to figure something 
out, but I can't figure anything out
 darkxst, the issue that RAOF was talking about was what happens when 
clamped and where the mouse is coming from end up to be the same thing -- that 
is, when we're bumping against a barrier on the screen edge
 so we switched to unclamped to allow for screen edges there
 now what's happening is that the unclamped mouse position is outside 
the bounds of the monitor, which the barrier doesn't reach to, so it doesn't 
consider it blocked
 darkxst, feel free to copy/paste this conversation onto the LP bug -- 
whatever solution RAOF comes up with is really interesting to me, because I'm 
turning his patches into a core X feature for 3.8.

[Ubuntu-x-swat] [Bug 1073724] Re: Pointer barriers have gaps along the edge of the screen

2012-11-01 Thread Tim
** Description changed:

- I have a multiple monitor setup and the pointer barriers seem to have a
- small (~1px) gap at the edge of the screen. For example in gnome-shell,
- the panel has barriers on either end, If I move the mouse towards the
- hot corner (top-right corner of screen) it inevitably just slips over
- the top of the barrier and onto the next monitor.
+ [Impact]
+ On a multiple monitor setup there is a small gap above the pointer barriers, 
that allows the mouse to slide through past the barrier, via the edge of the 
screen.
+ 
+ This a particular issue on gnome-shell, since the pointer barriers are
+ used to trap the pointer inside the panel/tray when activating hot-
+ corners.
+ 
+ [TESTCASE]
+ 1. run gnome-shell with atleast 2 montiors in horizontal configuration, 2nd 
monitor to the right of the primary
+ 2. move mouse towards top-right corner of primary monitor.
+ 
+ Pointer should get trapped in the corner of the primary monitor, however
+ it will actually just side over the top of the barrier.
+ 
+ With fix in the attached branch, the pointer is correctly trapped.
+ 
+ [Regression Pontential]
+ Should be minimal, I have tested under gnome-shell and unity and all 
hot-corners/sticky edges appear to be working correctly. 
+ 
+ 
+ === Original Bug Report ==
+ I have a multiple monitor setup and the pointer barriers seem to have a small 
(~1px) gap at the edge of the screen. For example in gnome-shell, the panel has 
barriers on either end, If I move the mouse towards the hot corner (top-right 
corner of screen) it inevitably just slips over the top of the barrier and onto 
the next monitor.
  
  This bug introduced by the '500_pointer_barrier_thresholds.diff' patch.
  I have rebuilt the xserver without this patch, and the barriers behave
  as expected blocking/trapping the mouser pointer in the top corner of
  the screen.

Passing in the unclamped x,y values to barrier_find_nearest(), fails to
find nearest blocking barrier in some cases. Since we are measuring
distance and not velocity I think its fine to use the clamped values in
*x,*y, as per my patch in the linked branch. This fixes the issues in
gnome-shell and does not appear to have any adverse affects in Unity.
