Can't move/resize onboard with touchscreen

Bug Description

Since a few days (maybe a week or two) I have the problem, that I can't move Onboard with a touchscreen. I can still type, but if I try to move or resize, Onboard moves only a few pixels.

I am using Precise 32 Bit without the Onboard PPA on a Viewsonic Virtualpad 10

Weird, I have no idea what could cause this.

Some questions:
- When moving/resizing, do the handles still directly follow the pointer?
In other words, is there an invisible limit where dragging suddenly stops?

- Is it always the same distance where dragging stops?

- Are frame handles and touch handles equally affected?

- Is the floating icon affected too?

As a shot in the dark, try this (default is -1 for system drag threshold):
gsettings set apps.onboard.universal-access drag-threshold 0

Ok, some more informations. I made a video.

Thanks, great video, I could see what happens very well. What this reminds me of is the times when I had my system running for a long time. Somehow moving onboard around then becomes choppy, but it never quite stops like in your video. I've put the blame on compiz so far, as restarting the session always fixed it.

I don't remember, are you using unity-2d? With or without compositing enabled?
Does it get better right after rebooting?

Onboard currently moves and resizes itself if window decoration is disabled. I've been planning to give that task back to the window manager whenever possible. This would allow for the less straining rubber band mode in compiz for example. I'll have to look into that.

Unity-3D does not work at all with a touchscreen. I am using Unity-2D. Not shure if compositing is on or of (can't check this right now). I made a full fresh install a few days ago and I did not change the default settings.

And it's not better after reboot

Asus T101MT, onboard unmaximized on start (Gnome Classis, Ubuntu 12.04).
Please maximize it at all width of the screen.

Norbert, I believe Bug #405034 and duplicates are a better match for what you're asking.

marmuta (marmuta) wrote :

I've made some progress on this bug. Trunk has "system resizing" now. Depending on the window manager and its settings, this may be less straining than Onboard's homegrown resizing. No change for moving yet, though.

Norbert (nrbrtx) wrote :

Thank you marmutta. I'm ready to test the Trunk version.
I removed old version with sudo apt-get purge onboard;
I downloaded the tarball, installed its dependency python-distutils-extra with sudo apt-get install python-distutils-extra
and after sudo ./ install.

But the onboard is still oversized, see screenshot.

Norbert, I misunderstood what you were asking for, but I still don't believe this is the right bug report for your problem. Please be so kind and create a new one. I'll try to help you there.

Okay, marmuta, I'm sorry. The bug for my problem now is available at

I believe this bug is finally fixed. Onboard trunk now has initial multi-touch support and moving/resizing works with the touch screen of the Nexus 7.
