I put my experience onto the wiki: http://knoppmythwiki.org/index.php?page=NVidiaDriversR5F27

Did anyone else get this error when installing from R5F1 /usr/src/debs/nvidia/latest? I did an AUTO UPGRADE. Not sure if the other mx440 folks did that also.

Setting up nvidia-glx (1.0.8776-1) ...
Creating NVIDIA TLS links... done.
ln: creating symbolic link `/usr/lib/libGL.so' to `/usr/lib/libGL.so.1.0.8776': File exists

Setting up nvidia-glx-dev (1.0.8776-1) ...
ln: creating symbolic link `/usr/lib/libGL.so' to `/usr/lib/libGL.so.1.0.8776': File exists

I have tried the following:

rm /usr/lib/libGL.so
ln -s /usr/lib/libGL.so.1.0.8776 /usr/lib/libGL.so

I'm still getting a black screen. I didn't save my XF86Config-4. Perhaps I just need a copy of a clean one?

Looks like someone at Nvidia heard the cries of the masses and worked out the kinks. All I had to do was install and then setup the TV out and everything was working fine on my test box...

I did a reinstall and found that the deb's found under
/usr/src/debs/nvidia/1.0.8776
fix the problem. This directory exists on your hard drive after doing an
R5F27 install, so there is no need to get the files from an R5F1 install.

I used the same procedure as the original fix. I will note though that final
dpkg -i had some errors that it could not create the symbolic links because
the files already existed, so I made the symlinks by hand, forcing it to
overwrite (or rm the links and remake them pointing to the files that
dpkg -i was trying to make them point to).

I also found that the 1.0.8776 driver is not available from the nvidia
download site any more.

I also did a reinstall and tried the following and it did not fix the problem
for me.
