I had a problem with guvcview on 14.04 except it was a segmentation fault. The fix for me was to clone the newest version using git.

First uninstall guvcview:

sudo apt-get purge guvcview

Then, install some dependencies:

sudo apt-get build-dep guvcview

Now, install git:

sudo apt-get install git automake build-essential

Clone the latest repo:

git clone http://git.code.sf.net/p/guvcview/git-master guvcview-git-master

Now, build and install:

cd guvc*
autoreconf -i -f
./configure
make

If there are no errors (ignore warnings), run the following command to install:

sudo make install

To run guvcview, run the following command:

guvcview &

To make a launcher for this application, run the following command:

sudo nano /usr/share/applications/guvcview.desktop

Then, copy and paste the following into the file:

Finally, press CTRL + o and then press ENTER to save the file. Press CTRL + x to exit nano.

Please post any errors.

Comment out line beginning with GRUB_CMDLINE_LINUX_DEFAULT="quiet...." and put the below instead. Afterwards, run sudo update-grub and reboot.

sudo gedit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 acpi_enforce_resources=lax"

In case it doesn't work, run this command in a terminal:

sudo bash -c 'echo -1 > /sys/module/usbcore/parameters/autosuspend'

Reboot. Good luck.
