new at this, sorry

[Brian Murray (brian-murray)]

Could you give some more information about the exact problem you ran into? Based of the title of this bug it sounds like compiz crashed and the core file isn't the size that was expected. This can happen if your system ran out of memory when writing the core dump. If that's the issue then this just happens sometimes and the bug should be invalid.

[Brinstar (brinstar)]

Gives me the same error just after boot to desktop

[Brinstar (brinstar)]

I have 8gb ram, pretty sure it's not running out unless there is a serious memory leak going on

[Terry Relph-Knight (tarki)]

I get the same problem (truncated core) every time, a few seconds after I boot 17.04.

[Brinstar (brinstar)]

How are we supposed to report this if the core dump is getting truncated and apport doesn't let us proceed to send the report?

[Brinstar (brinstar)]

This happens at boot-up after starting Ubuntu 17.04.

I'm running the official Nvidia driver (340.xx) if that has any impact.

[Benjamin Wynne (bwynne)]

I have this bug too. First time I checked the message it was just complaining about some out-of-date dependencies and told me to run apt-get update. I did (sorry, didn't record what was installed) but now I get this "truncated core" bug instead.

There is 32GB of RAM available, so I'm very sure it's not running out!

Just encountered this after upgrading from 16.04 to 17.10
