Camorama Webcam Viewer performs flawlessly


sudo apt-get install libv4l-0

Then run:

sudo updatedb; locate v4l1compat.so

What is output?

Also, have you tried a different USB port?

(1) Have tried out all available USB ports problem persists (2) Used GUI to activate Cheese after getting above output,not even flash of image,only black screen.Have reported Camorama works OK

Ok now run:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese

Is it better?

kesava@kesava-Desktop:~$ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese
NO BETTER , Saw something like a " few spokes on a wheel flash by" then all is dark.(CHUCKLE)

Strange how there is no output in termnal. Have you tried a different USB port?

kesava (chandran-kesava) said : #9

Have Six USB ports , tried all result is same,interestingly another HDD with Ubuntu10.04 Lucid has Cheese really "Cheesy"Kindly go through my just sent mail with attachments of Screen Shots.Lets get to the root of the problem,will get back after Lunch.If you have time I have the patience

kesava (chandran-kesava) said : #10

I tried a work around suggested by MREDDING in http://ubuntuforums.org/showthread.php?t=1745517.viz edit >preferences trying out 320x240,picture was steady got back to 640x480 with similar result but in my next trial the picture flashed by leaving same dark screen.This time i had got cheese via Terminal$cheese and have got an interesting output likekesava@ubuntu:~$ cheese
The program 'cheese' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 377 error_code 9 request_code 133 minor_code 19)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
As i can't make head or tail of it this should give the break to actonparsnip who initially was my guide/mentor and to marcobra

Before i could add a word of thanks to MREDDING and the quoted forum, the earlier message got through???

kesava (chandran-kesava) said : #12

I have got into a new positive development.Cheese will function normally but only for the default output of $sudo cheese --sync meaning every time you have to use terminal and go by the command line mentioned.This is admittedly only a workaround.The Bug persists,will have to be remedied appropriately

kesava (chandran-kesava) said : #13

Some thing more to add $sudo -V clear gdk_x_error will enable start cheese /run cheese with all applications such as full screen etc with the following terminal command as root like $ sudo cheese ENTER.

Great testing dude. I admire you tenacity. If you run:

ubuntu-bug cheese

It will start the bug reporting sequence. I suggest you use the link near the top of this page to link to the bug number too. Sounds like a regression to me. Possibly group related.

kesava (chandran-kesava) said : #15

Thanks actionparsnip, that solved my question.

kesava (chandran-kesava) said : #16

Thanks, got a similar compliment years back from Jean Simon Durant, Technical Expert, Linuxant ,Canada.It was a task to fashion the Beta driver with Conexant Hard Modem on Red Hat 8 with success of Dialup connection.Only soft modems could be used before this successful experiment As a memento have the original LINUX HSF softmodem driver version 5.03.27 lnxtbeta 03042700 and the email note from Mr. Durant.
