[Bug 1394977] [NEW] Slow unity panel loading during first login

 

Public bug reported:

It takes about 10 to 15 seconds to display the menubar, the unity
starter and desktop icons during the first login. It usually took half a
second, so this looks like a bug. Right before these show up, a short
black frame indicates some component crashed and was restarted. After
this delay the performance is fine as usual.

I tried to debug the performance drop during these 10 seconds with top
in the terminal, but did not know what to look for. Unsurprisingly most
active processes were sysvinit, xorg, compiz and unity, but all about 1%
CPU usage at maximum.

First occurance has been about one week ago, it did not happen directly
after the fresh installation of the 14.04.1 image .

I don't use proprietary drivers and didn't mess with xorg edgers if I
remember correctly. Could be a bug of unity or compiz, too.
