work and the issue appears when a external monitor is connected when login

For your crt/lcd monitor - maybe this issue depends on the resolution
of the external screen.
Does appear that issue if you have connected your screen at boot-time,
then disconnected when the lightdm login screen is showing and you
logged in (without connected external screen)?
Today I had the
Okay, I did a few more tests...
- the external monitor is connected at boot time, I disconnected it when
the login screen is displayed, logged in, no high cpu usage
- logged out, connected the monitor, logged in, HIGH CPU USAGE

A note for all those commenting on this, my understanding is that if the

different bug.

I'm not sure if this fits into this particular bug, but maybe it helps
to locate the problem...
I have a netbook with Intel Atom N455 and GMA3150. The netbook has an
external monitor attached to it via a KVM switch (USB mouse and
keyboard, VGA) and has run Ubuntu since 11.10 (13.10 upto yesterday
@Stephan you are now the 3. or 4. who has this issue when an external
screen is connected at booting. That seems to call for a new ticket. But
I installed todays updates (14.04), rebooted and all good. Currently
compiz does not use 50% of cpu power any longer.

Good to hear it's solved for you!
The strange thing is that I just replaced that broken CRT with the new
LCD monitor. Just disconnected the old monitor and connected the new
one. Boom, high CPU usage :-(. I didn't install any new software, etc.
I never had this before in 2,5 years and as I said
nope, I must correct myself. Same problem as described by Marco in #70.
The issue remains when a external monitor is connected at startup even
it isn't used and the Mesa environment variable is set.

My bug turned out to be a different one, but it manifested itself similar to

Olibaf: the new driver is a great improvement, but it is still not good
enough I am afraid. For example, with the new driver the Dash still
takes about 4 seconds to show, coming up in several steps. With the

than 0.5 seconds.

is a big help on restoring desktop action. This netbook + external monitor has
been running ubuntu fine since 10.10.
The downgrade to 1.4 workaround causes a different code path in Unity
to be executed, and that uses a much simpler blur function. It looks
OK, but to the expert eye it doesn't look near as good. Don't ask me
what the difference is: it all looks blurry to me even with my bifocals
