You can verify this incorrect transform using 'xinput map-to-output 7
LVDS-0' followed by 'xinput list-props 7' and examine the values of the
input transformation matrix.

[Bug 1613708] Re: Some Xapps buttons are not responding

2016-08-17 Thread Stephen M. Webb
The problem is caused by commit d19641fc01f77420b4ec5d6db6723f519f8f8272
which fixes bug #1602561.

That commit deletes the code that removes the XRandR outputs associated
with the XMir screen after a resize.  That means that whatever XRandR
configurations are created at XMir startup remain in place for the
lifetime of the process even if they do not correspond to the actual
size after an X11 resize and rotation (XRandR) and input events get
transformed through a matrix corresponding to the original size of the
screen.  When all the outputs were deleted previously, the identity
matrix is assumed for input remapping.

Here is the debdiff between the version of xmir in the overlay (working)

Update:

So I tried rotating the tablet into portrait mode as suggested, and the
buttons suddenly work!

I'm not sure where the bug lies in this case, but wherever the bug is,
the version of xmir that is currently in the overlay is not affected by
it whereas the overlay candidate is.

2016-08-17 Thread Christopher Townsend
Hey Daniel,

I do not see this issue on Yakkety xmir on desktop, nor do I see it on
Xenial+overlay using a locally compiled xmir made from the head of the
xmir git tree.

However, I can reproduce the issue described in the bug on my frieza
using the version of xmir found in the Vivid overlay candidate at
https://launchpad.net/~ci-train-ppa-
service/+archive/ubuntu/landing-053/+packages.

Perhaps the patch was not fully applied or something else is missing?

2016-08-16 Thread Daniel van Vugt
I can think of two more reasons why buttons would become unclickable:

1. One of your modifier keys (Alt/Shift/Ctrl) are either physically or
logically (in software) stuck down. Try tapping all the Alt/Shift/Ctrl
keys. This is definitely a problem for X apps under the Mir demo servers
after you Alt+Tab but not a problem under Unity8 AFAIK.

2. Try rotating the tablet to a different orientation. You might be
experiencing a problem similar to bug 1502805.

Sorry, ignore bug 1590553... Both its description and its fix apply to
-rootless mode only, which we don't use in Unity8.

[Bug 1613708] Re: Some Xapps buttons are not responding

2016-08-16 Thread Daniel van Vugt
I've been trying and can't seem to reproduce any such bug with the
latest Unity8 and the latest Xmir in yakkety. Everything is clickable in
LibreOffer and Firefox.

It's possible your vivid image is missing the most recent Xmir fix that
was bug 1590553 (like what you describe).

It's also possible matchbox-wm is misplacing windows as looks like the
case in your video (the dialog should not appear on the right hand
side). It also seems that matchbox-wm will ignore mouse input in the
non-focused window without making it obvious which one that is. So try
clicking around to see what is responding.

Sorry, I also don't have an M10 to test with. But I can at least say
that I can't reproduce this with the latest Xmir.

Sounds like bug 1590553, but the PPA you refer to seems to have that fix
already.
