I downloaded the development version of 14.04, one issue that I've experienced so far is that the fade in of the greeter after resume from suspend is very slow. I have opted out on the fade in/out effects in compiz configuration settings, why do I get fade in/out for the greeter and is it possible to increase the speed of the fade?
It also is a noticable delay for visual feedback (*) when entering a password character in the password prompt.

I tried to install the linux performance tool - perf -. to get an idea of what's happening. While in the unity-greeter I ran in a console
sudo perf record -a -g
then holding the 'a'-key in the password field for 10-15 seconds
and then
sudo perf report

it seems like much time in used by compiz process and r300_dri.so?

In the compiz setting manager for openGL plugin I disabled "FrameBuffer object"/"Vertex Buffer object" and "Always use Buffer swapping" options. And the fade in/out is faster now. |

----
This testing was based on a 32-bit 14.04 running on a 64-bit processor
*-cpu
product: Intel(R) Core(TM)2 CPU T5600 @ 1.83GHz
vendor: Intel Corp.
I've no upgraded my system to 64-bit Ubuntu 13.10, and its noticable more performant (e.g video rendering in fullscreen). So lesson learned: if available run 64-bit OS on 64-bit processor. |
