This is what I see at bootup, some "errors" that appeared "now" after installing the kernel.

I reinstalled the windows in order to upgrade the BIOS, then I installed the generic 64 bit kernel
(the: linux-image-3.19.0-031900rc5-generic_3.19.0-031900rc5.201501180935_amd64.deb)

This is what I see - again:
https://www.dropbox.com/s/2c2h0wj06anj0tx/20150128_001849.mp4?dl=0

output of the:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
is:

Sándor Iorgu Weisz-Cucoli, given this works in Skype, but not in Cheese or in browser/flash, this would indicate an issue with the respective programs, versus a driver bug.

Hence, let the scope of this report focus on how it doesn't work in Cheese. Hence, could you please provide the error message verbatim?

The error that I get in Cheese:

"Hiba történt a webkameráról történő videó lejátszása közben." Which would translate to something like: "Error occurred playing the video from the webcam"

Here, there is no error message, and the screen is "black-blank": http://webcamtoy.com/
in Google+ Hangout the image appears but distorted with lines, no error message, but at the start it appears good.
I'm attaching what I see.

Sándor Iorgu Weisz-Cucoli, could you please test http://cdimage.ubuntu.com/daily-live/current/ (live environment is fine) and advise to the results?

Still, the error is present.

And at the entrance/log-in I can't see the password field. Some translations are missing as well.

Sándor Iorgu Weisz-Cucoli, the screenshots you are providing aren't terribly helpful, as they don't provide any further information regarding what error specifically is occurring.

Could you please run cheese from a terminal to see if it logs something more verbose?

As well, regarding the password field and translation issues, those are not scoped to this report. If you want those addressed, please file a new report about those, one per issue.
