update-manager (1:17.10.15) artful; urgency=medium
* Block style context changed signal while enforcing the main window's
constant size. Thanks to Thomas Waldmann and Sebastien Bacher for the
initial analysis
Verification-done on artful, using update-manager 1:17.10.15:
Verified that the application does not take 100% CPU while waiting for
input at the "computer needs restart" dialog; and the expected code
changes are applied on the python modules on disk. Applying updates
completed without issues.
Hello Giuseppe, or anyone else affected,
Accepted update-manager into artful-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/update-
manager/1:17.10.15 in a few hours, and then in the -proposed repository.
Please help us by testing this new package.
This bug was fixed in the package update-manager - 1:18.04.11.2

update-manager (1:18.04.11.2) bionic; urgency=medium
* Fix my embarassing typo that makes update-manager report crashes, when
instanciating the "reboot" dialog and mangling signals. (LP: #1774131)
Verification-done with update-manager/1:18.04.11.2 on bionic:
Verified that the restart CPU does not show 100% CPU usage, and it does
show without crashing update-manager. AFAICT this is fixed correctly.

Hi,
Unfortunately I'm still on 16.04, waiting for 18.04.1 to upgrade, so I
can't test the proposed right now...
Thanks for all the effort at fixing this annoyance!

This issue has priority "high" and is now over one year old.
A fix is known (see my post above) - I apply this diff each time a
update-manager update overwrites the patched version on my laptop and it
works ok for me since I wrote it.
So, can we have this finally fixed, please? In all supported

some guessing work/suggestion here, resize_to_standard_width() does
ctx = self.get_style_context()
size = ctx.get_property("font-size", Gtk.StateFlags.NORMAL)
that's likely to create a "changed" event and trigger the loop
the usual way to fix those is to call

Hi Brian,
do you know some way to get a good backtrace for your purpose? Note that
this is 100% reproducible, just run update manager, and even if it tells
you that the system is up to date, switch window focus to somewhere else
to trigger the 8-10% CPU usage.
A quick gdb -p PID and bt doesn't
I meant backtrace not stacktrace.

Thomas if you could get a stacktrace of update-manager so we can figure
out what it is doing that would be helpful. If we can fix it then yes
we would fix it in stable releases, including Ubuntu 16.04.

@brian I also have intel gfx (haswell generation integrated gfx) in my

update-manager waits for my final click - which is kind of superfluous
anyway for cases where updates worked flawlessly).
So I am wondering whether this gets

I tried recreating this on zesty with update-manager version 1:17.04.3
and I did not notice update-manager using CPU. One other difference from
the original reporter is that I am using an Intel graphics adapter. I'll
keep testing though.

I found out something interesting right now:
- when the update manager dialogue box is the selected window, it does
not suck a lot of cpu
- but when you select something else (an icon, another window, does not
matter), cpu usage of update-manager, compiz and xorg jumps upwards (see
screenshot in
In that case, X usage goes down, and of course compiz isn't there any
more, but the dialog is still eating CPU. I don't know anything about
GTK nor python, so I don't really know how to track this down, otherwise
I would've already done that...

Could you try disabling compiz, if it has an effect?

Yes. It's likely caused by some broken code calling update() in a loop
or something like that. Yet, we're looking at a 30-40% aggregated
between the app, X and compiz.

Do CPU usage of Xorg and compiz decrease a lot, too, when you close the
dialog?

Attached a screenshot with proof.
When I close the dialogue, the cpu usage seen on the screenshot
vanishes, so it is definitely the update-manager dialogue causing this.
This is a real annoyance and I am asking myself how many kWh get burned
down every day without reason due to this.

I do not notice CPU usage of "computer is up to date" dialogue box.
Maybe it is some hardware driver that uses the CPU power?

Also affects me and is not limited to the "needs to restart" dialogue

It also happens for the "computer is up to date" dialogue box shown

Maybe for ANY such dialogue box?
Please fix, this is a real annoyance to having to click on "OK" just to
stop the CPU fan
