xterms broken in unity

[Fabien Tassin]

In Natty, when i start an xterm while in unity, i get a transparent window (unexpected), with decorations, and it's totally unresponsive and unusable (it's not accepting inputs).

I can't grab it or move it, it seems to let some events pass through to nautilus in the background, like if the xterm is over a file or a folder, even if it does do anything when i click on it, i can drag "something" and if i drop it in.. say a gnome term, i get its filename.

As i use xterms instead of gnome terminals (faster & lighter), unity is totally unusable for me at the moment.

It's totally reproducible here.

(moving back to Classic, i revisit Unity periodically)

still unusable with 3.2.14-0ubuntu2. it's probably just a z-axis issue as an xprop of the xterm shows it's in fact nautilus.

[Fabien Tassin (fta)]

slightly more usable with 3.4.0-0ubuntu2, but it's still impossible to resize xterms.
The decorations are resized, but not the content.
Also, only the top border is usable to resize the window, and not even the full width (a click on the right part of the decoration title bar passes through to nautilus).

Can't find the right branch to push to ... attaching a patch instead

[Fabien Tassin (fta)]

I tried the patch, it works fine for the xterm itself, but there's a new problem: the xterms are moving unexpectedly when switching workspaces.

It's easy to reproduce:
open an xterm on a workspace, move to the next workspace and back. the xterm moved a few pixels upward. Do that several times and the title bar goes underneath the top panel, making the xterm unmovable (except with Alt+F7).

[Mikkel Kamstrup Erlandsen (kamstrup)]

xterms works perfectly well for me and I can't reproduce any of the symptoms. Would be most odd if this was GPU related (i have an i945 here).

@Fabien: Do you have some non-standard xterm config or something that may trigger this?

[Fabien Tassin (fta)]

@kamstrup: no, and i can reproduce at will on different boxes. iirc, smspillaz said he knew what the new problem is.

hm, not completely fixed. See #4 and #6

[Fabien Tassin (fta)]

Here is a patch fixing the regression I mentioned in #4 and showed in #7.
wfm now.

[David Barth (dbarth)]

Hi Fabien,

Here is the additional branch i just merged earlier today: https://code.launchpad.net/~unity-team/compiz/trunk.fix-xterms/+merge/56144

Could you review it as well (even if it's already merged in) and confirm that does fix the problem in your context as well. It seems to be a more general version of your patch, but I'd like to ensure the "extra bits" don't create regressions elsewhere.

David

[Fabien Tassin (fta)]

David, just by reading the patch in the merge proposal, i see the regression is still there.
I can try it tomorrow if you want but i doubt it will work.

[David Barth (dbarth)]

Sam says you're right ;) So i'll apply the patch, considering that this thread is equivalent to a code review. Thanks!

[Stephen M. Webb (bregma)]

Looks like this has been in trunk and released for the last several releases.
