Bug Description
I'm on Ubuntu 14.04 (Trusty), up to date, on a computer with an NVidia GTX 750ti graphics card. I also tested on Utopic with a live daily dvd and the problem persists.
The list under Additional Drivers is empty for my NVidia GTX 750ti video card:
Also, running:
or
produces an empty output.
Running:
or
kcmshell4 kcm_driver_manager
shows no drivers found (not even the open source driver). I'll attach a screenshot here to show this.
I had to workaround by installing the "nvidia-
The empty list happens because the "ubuntu-drivers" command insists on making a perfect VID:PID match with each driver, and also because the specific modalias for making that match, is missing from nvidia-331 deb package.
The corresponding modalias for my NVidia 750ti is (as obtained from running "ubuntu-drivers debug"):
Which means that this should be included in the driver package description for my card to be matched by the Additional Drivers backend:
wich is currently missing from the Modaliases list in the description of the .DEB nvidia packages. That is the modalias required to make a match for the 750ti card.
There are two possible solutions:
-------
A) Please ask the maintainer(s) of nvidia packages to add that modalias to the DEB package of "nvidia-331" and "nvidia-
B) OR Please ask the developers of "ubuntu-
Important Details
-------
If I look at the current list of modaliases in the nvidia drivers, by running:
apt-cache show 'nvidia*' | grep -i modaliases
I cannot find my NVidia 750ti, which has a VID equal to 10DE, and a PID equal to 1380. I should be able to find the string "v000010DEd0000
This causes the detection routine in "ubuntu-
There is a very big list of nvidia cards that COULD be affected by the same problem (empty AdditionalDrivers), not just my 750ti. This can be verified by looking at all the product ids for nvidia cards, and comparing to the modaliases present in the nvidia drivers packages:
"The PCI ID Repository"
http://
and looking at the current full list of modaliases with:
apt-cache show 'nvidia*' | grep -i modaliases
For instance, the NVidia 780ti and NVidia 780 are both missing too:
apt-cache show 'nvidia*' | grep Modaliases | grep d00001007
apt-cache show 'nvidia*' | grep Modaliases | grep d00001008
(produces empty results)
Though a "NVidia GT 610" that I have in an old computer of mine, can be found, and does show a list in Additional Drivers:
apt-cache show 'nvidia*' | grep Modaliases | grep d0000104A
(shows a long modalias line matching for nvidia-304 and nvidia-331 packages for the old GT 610).
Please make Additional Drivers selector work for my NVidia GTX 750ti video card.
FYI: This video card was released by nvidia in february 2014.
Your help will be appreciated!
Cordially,
