Selecting nvidia driver using software-properties-gtk yields package nvidia-361 361.28-0ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 30

I gave it a try again since Xenial is out.

This time install appeared to work. At least it did not show an error message at install time.

On next boot, no graphical login was observed. Screen was just black.

Since I don't know if it is a different bug, I report it on https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1575907 .

On another laptop (Asus X77VN) same procedure worked without problem and provided a working nvidia driver with 3D support. Not on this laptop.

Thank you for your attention.

Ubuntu 16.04 with nvidia drivers 361 and 364 are NOT working here either in a laptop with intel and nvidia GeForce 940M.
Using either these drivers and nvidia-prime, its installs and works at first graphical boot, after a few minutes the system freezes and only after a hard reset the drivers don't work anymore.
Also, I only managed to get working the driver 361 with bumblebee, however after a suspend the nvidia card cannot be used getting a error of fallen off the bus and the message refused to change state...

In conclusion, these drivers are NOT WORKING!!!!!

I only get the system perfectly working using the 352 drivers and nvidia-prime, the install of the 352 nvidia driver is not working through apt-get and ppa:graphics-driver/ppa,
I had to manually download them from the site and install them manually.

Please fix these!!!!!!!!!!!!!!!
Or at least give the people the option to install the 352 drivers through the Additional Drivers in Software and updates.

Thank you Nuno for reporting the trouble you observed. I'm the one who posted this very bug report where you added your comment.

I can understand your frustration. I'm frustrated too. I'm using open-source nouveau driver instead and it has problems, too cf. https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547077 , and on top of that all these are regressions from older Ubuntu releases.

In any case, in any open-source and unpaid context, please refrain from using several question marks or writing some words in all capital letters, as its main effect is to turn people away.

Thank you for your attention.

Closing as package was updated since then, and original reporter noted issue scoped to this report no longer occurs as per https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1575907 .
