Unity 14.04 Lock button sometimes takes 30~60s to enter lock screen

[Franz Hsieh]

[Impact]

When the power button is pressed, the shutdown dialog will be displayed. Then clicks the 'Lock' button in the shutdown dialog and it sometimes takes about 30~60s to lock screen. This happens on many Intel-only platforms.

PS: If user moves the cursor out of the dialog window after clicking the 'Lock' button, it will switch to lock screen immediately.

[Test Case]

See description under "Impact' above.

[Regression Potential]

The fix for this problem involves releasing the grab on the input devices earlier in the sequence, allowing the animation sequence to begin immediately without a grab-release timeout. It is unlikely that this could introduce any regressions.

[Other Info]

This fix was cherry picked for Ubuntu 14.04 LTS from the Ubuntu "Vivid Vervet" dev release where it has been in test for some time without incident.

What you mean for HUD?

[Franz Hsieh (franz-hsieh)]

@Andrea

I do not know its exactly name, I posted the screenshot.

[Andrea Azzarone (azzar1)]

I managed to reproduce it but just not every time. Do you have a reliable way to reproduce it?

[Andrea Azzarone (azzar1)]

Btw this is due to the way nux animation and compiz work. Basically can happen that an animation start later because the screen is truely idle. In this case the grab will be released later and the lockscreen will be delayed. The best way to fix this bug is to call cscreen->damagePending() as soon as we start a nux::animation.

I've only checked it in VirtualBox but Franz Hsieh the original bug reporter mentioned earlier in comment #9 that this was fixed.

The locking isn't immediate but it happens after about 5 seconds so it's a good response time from GUI.
