Scott, could we get python3-virtkey updated to 0.62.0 in the Nexus 7 PPA too? This would allow Onboard to show proper key labels for the number block and fix the action of the NumLock key. Raring has it already (0.62.0-0ubuntu1), though I've only now updated Onboard's version requirements.

Hi Scott, Thanks for making the package available in your PPA. The next release superseeding the 0.98.2+tr1071 package that you are going to upload to your PPA will be 0.99.0. Onboard 0.98 is our current stable branch. It is not excluded that some day a 0.98.3 version with bug fixes for the 0.98 branch will appear. But it will not contain the improvements for the Nexus 7 that are currently in trunk. These will be available from the 0.99 branch, which will be created from trunk, when the changes for the Nexus are going to be released.

It's barely usable even with the simplest themes, where just a plain filled and stroked rectangle is drawn per key. A cairo-perf-trace of Onboard starting up shows the Nexus 7 to be ~200x slower than a Sandy Bridge i3 laptop, but single-threaded CPU performance differs just by a factor of roughly 4.5 (see Attachment). Also the cairo image backends are vastly faster than the xcb/xlib one's, which is the reverse of the i3's results.

Good news, I've been able to squeeze some more performance out of Onboard, with a lot of optimizations and a little bit of corner cutting. A warm start with Compact+Ambiance is down to around 6 seconds. The other themes a second or so less. Most typing has become more fluid too, the delays on modifier presses and layer switches are shorter most of the time. The splash-screen like empty frame on startup is gone, Onboard just pops into existence when it's ready. I'll mark the Onboard part as committed, but more speed improvements will likely come over time. ** Changed in: onboard Status: Confirmed = Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1070760 Title: 1st time running onboard with default theme is painfully slow To manage notifications about this bug go to: https://bugs.launchpad.net/onboard/+bug/1070760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've opened an upstream bug here: https://bugs.freedesktop.org/show_bug.cgi?id=56891 CPU performance isn't that bad, almost a quarter of the i3 per thread. It's apparently just cairo rendering to the xlib/xcb backends that takes the big hit. I'm not sure why, either the intel driver on the i3 accelerates cairo really well or the tegra driver does extremely poorly. The weird thing is, cairo rendering to image backends is almost 10 times faster than to the x backends. I would try and exploit this to speed up Onboard, but then it would be the reverse on intel... Perhaps we need something closer to OpenGL for rendering, that's where the Tegra shines.
