Where can I get the right version of the loader?

http://bitbucket.org/ahixon/r5u87x/get/32a27008b8b9.bz2

Which is a .tar.bz2 file

Sorry but the problem persists.
I have checked the patch and the file is not the right one!

Sorry,

You are completely right, the patch I've provided should be applied on top
of this one:
http://people.fedoraproject.org/~jwr...are_path.patch

Whicc moves the firmware files to the standard /lib/firmware directory.

So download:
http://bitbucket.org/ahixon/r5u87x/get/32a27008b8b9.bz2

And then apply:
http://people.fedoraproject.org/~jwr...are_path.patch

Followed by:
http://people.fedoraproject.org/~jwr...der-flip.patch

And then do the usual ./configure, make, make install

Also if your distro (Ubuntu I guess) provides packages of the loader, please consider filing a bug with a link to the flip patch and ask them to
include this.

Sorry for not providing proper instructions before,

Regards,

Hans

Hi, thanks to all for all the info in the thread.

I´ve tryied many options till I reed about the update of libv4l. I'm trying that now, but I don't know what to do after compile I reed the info in the text files in the root of the lib source but didn't find any there... I suppose maybe that's to basic to include there, but I had no lucky searching for "install libv4l"... BTW, I dowloaded this file: libv4l-33606f40c9ca.tar.bz2

The compiling seems to be ok, just a few warnings here and there, but I'm sttuck...

Hans, I didn't send you the info becouse I don't know if it's already in the table (becouse I could not prove it) I'll copy it here, if it's better for you have it in your mail just say it and I'll send it.

Ok,

So for those who wish to try and see if libv4l fixes their upside down
issue (it has a list of 40 + laptop models included now, so should work
out of the box on most machines), do the following:

Download:
http://people.fedoraproject.org/~jwr....3-test.tar.gz

Then to make sure no old versions get in the way (only needed if you've
tried to install libv4l manually before):
rm -fr /usr/lib*/libv4l* /usr/local/lib*/libv4l*

And then follow these instructions to install the new version:

Thanks a lot! I've just tested it with cheese and it works perfect. Tell me if some other info is usefull for you, I would be pleased to be of some help!

Best regards

Hans, that's great, thanks much! For anyone else, I'm using an Asus G50VT-X5. Spent alot of time fishing around--it's such a common problem, that's there's a lot different approaches. For me, this approach worked well. I use the *0.6.2 version and followed your directions you noted on http://hansdegoede.livejournal.com/7622.html.

Thanks again!

Sorry, I spoke too soon...the image has been corrected in Cheese, but is still upside down in skype which will be all of my use. The skype version is 2.1.0.47. Any ideas?

[cj4linux]

I'm getting this when I'm trying to use LD_PRELOAD with skype:
ERROR: ld.so: object '/usr/lib64/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored.

I'm using the 64-bit beta version of skype, version number noted above.
