Cheese works intermittently on LTS 12.04

[John Berkhout]

Problem reproducable?
Yes, just start cheese. It displays the program window. The part where the webcam should work is black.
Sometimes it works, but there seems te be no pattern.

My problem looks like Bug #991430
So I always start cheese via the Unity icons. This mostly results in a non functional cheese.
When is start cheese via a terminal I see this:

[John Berkhout (jfberkhout)]

after upgrading to kernel 3.2.0-24-generic-pae the cheese window remains black, so no image.

There is also another error. type "cheese" in a terminal:

Status changed to 'Confirmed' because the bug affects multiple users.

[John Berkhout (jfberkhout)]

Can we have an update on this one, please?

[Xolotl Loki (xoloki)]

I just got my webcam plugged in on 12.04.1, and cheese hangs on startup. Here's the stack:

So the problem appears to be that

  gnome_desktop_thumbnail_factory_generate_thumbnail()

does an exec(), and cheese gets blocked in waitpid() waiting for the thumbnail to complete.

Interestingly, I don't see any hung gnome-* processes:

ps auwx | grep gnome

I'm about to download the source so I can figure out what's going on...

[John Berkhout (jfberkhout)]

Hi Loki,

Any luck?

[terryK9 (terry-kemmerer)]

I have the same warning on the commandline as the others above. When I launch cheese, I see only an empty white window and my resources climb until the process self aborts.

I hope someone solves this, as I am kind of committed to 12.04. Apparently 12.10 works fine...

Thanks!

[Tony Dalmeyer (tdalmeyer-gmail)]

This is one of the many bugs i have come accross.I can confirm it also doesn'twork in Cinnamon Mint.
Wtf
I have persisted with Ubuntu for years and finally had 12.04 running sweetly untill I was forced to update.
Switched to Mint and still have numerous bugs to fix.
A computor is supposed to save time,right?
I think its time to return to Windows or at least ios.

[John Berkhout (jfberkhout)]

This bug is still present in 13.04.

[John Berkhout (jfberkhout)]

But the errornotification changed. Open terminal and type cheese:
