[Ubuntu 16.04] huge Problems with nvidia drivers

[gfoxhound]

Hello
Iam an old kubuntu user since 2008 exactly. Until Kubuntu 14.04 it was really perfect, for me at least. I decided to upgrade towards Ubuntu 16.04, and there is the big problem. Once I installed Ubuntu 16.04, as it is slow, I decided to switch from generic video driver, to Nvidia's driver, as I used to do before. It does not work.
I followed the script availlable here
https://askubuntu.com/questions/7609...vidia-graphics

Now for the fix

1. Log into your account in the TTY.
2. Run sudo apt-get purge nvidia-*
3. Run sudo add-apt-repository ppa:graphics-drivers/ppa and then sudo apt-get update.
4. Run sudo apt-get install nvidia-375.
5. Reboot and your graphics issue should be fixed.

If you run into problems afterward, you should ask a different question. (Refer to this question so that we know it isn't a duplicate.) However, there are a few other small fixes you can try out before you do.

• Reinstall Xorg
  
  
  • Go back into the TTY and run sudo apt-get purge xorg-* xserver-xorg; sudo apt-get install xorg xserver-xorg; sudo dpkg-reconfigure xorg.
  
  
• Reinstall your desktop environment
  
  
  • If on Unity, run sudo apt-get purge ubuntu-desktop; sudo apt-get install ubuntu-desktop.
  • If on GNOME run sudo apt-get purge ubuntu-gnome-desktop gnome-desktop-environment; sudo apt-get install ubuntu-gnome-desktop.
  • If on MATE run sudo apt-get purge ubuntu-mate-desktop mate-desktop-environment; sudo apt-get install ubuntu-mate-desktop
  • Each Ubuntu DE has its own package name. If you have KDE or something else, the name should be similar to the ones above.
  
  
• Fresh reinstall
  
  • It's not the most inviting option, but sometimes it's the best thing to do in cases like this.

But the big problem, I was unable to connect into my account. Is it a workaround ? Does it exist a solution please ? Why did Ubuntu's team change things that worked perfectly before ?
My computer's config:
Notice it works perfectly before, no problems with Kubuntu/Ubuntu 14.04. No problem with Win 7, or Win XP. The only problem I have met, is with Ubuntu 16.04, 17.04.

gfoxhound; Hello;

That card is old ... takes the 304 driver:
http://www.nvidia.com/object/IO_32667.html
Soon now to be no-longer-supported:

The Linux 304.* legacy driver series is the last to support the NV4x and G7x GPUs and motherboard chipsets based on them. Support for new Linux kernels and X servers, as well as fixes for critical bugs, will be included in 304.* legacy releases through the end of 2017.
See: http://nvidia.custhelp.com/app/answe...y-gpu-releases

But for now we need to clean this system up and get the 304 driver installed.

post back:

dpkg -l | grep -i nvidia
lsmod | grep nvidia
lsmod | grep nouveau
ls -al /home/<username>/

where "username" is your actual system username .

ain't nothing but a thing

[gfoxhound]

First of all thx for your quick answer and your help.
In spite of the fact that Iam java developper, Iam far to be an expert in unix area-the rare commands that I know are....mkdir, cp, mv, ls, but grep I don't remember, it is a while that I don't see this command. Sorry but nobody is perfect -. Very far. What commands lines exactly should I write.
Moreover, I searched in nvidia website
http://www.nvidia.com/Download/index.aspx?lang=en-us
I found this driver
http://www.nvidia.com/download/drive...x/114718/en-us
is it correct ? However as I said U, in ubuntu 16.04, I reached the interface TY, I see username, and password, but I could not log in. If I download the driver, what should I do in this case ?

PS: Again thx for your help.

gfoxhound; hey;

Hey. not to know is not a sin . None of us know it all . I just have a bit of experience with the nvidia driver .

What we want here is the 304 version driver.
Getting a driver from nvidia direct is the means of last resort . The driver in our repo is optimized for ubuntu .
It is available in our software repository:

apt list nvidia-304

OK, let's proceed and get this driver installed from the repository.
1st is the find out why you are not able to log into the system:

I see username, and password, but I could not log in. I see username, and password, but I could not log in.

Let's "presume" that "you" do not have the authority to access your desktop.
Verify authority :
At the grub boot menu -> advanced options -> recovery kernel -> root access .
Now what shows from terminal command:

ls -al .ICEauthority .Xauthority

show me this complete output - checked for typos .

Once we have access to the system as "you" we continue in the process to get the proper graphic's driver installed.

we can do this

[gfoxhound]

Thx Bashing-om for your help, and your quick reactivity.
We are saturday night, nearly 23:00. I will do it tomorow sunday.
However let's resume what I must to do

First of all, I must to login with my username and passworth, by executing this fragment of code

ctrl+alt+f1
// login into terminal mode and must execute this code
ls -al .ICEauthority .Xauthority

Once it is done I must to follow these statements

dpkg -l | grep -i nvidia
lsmod | grep nvidia
lsmod | grep nouveau
ls -al /home/<username>/

and finish by

apt list nvidia-304

Is it correct ?

[Bashing-om]

gfoxhound; Mostly Yes.

All we are doing here is attempting to activate a console interface ( ctl+alt+F1)
See what is on the system ;
see that the desired driver is available ( apt list nvidia-304)

then we do the actual install if all is clean and proper.

leastways. that is my thoughts

[gfoxhound]

Hello.
I could not login again. I applied the scripts that I described above. It is still the login screen.

PS- I applied obviously apt get update and upgrade, else I don't know how to set up the driver nvidia -304

[Bashing-om]

gfoxhound; Hey;

Sorry, I am unable to establish a point of reference as to logging in.

so, in small steps. What results when at the login screen you attempt to activate a console interface with key combo ctl+alt+F1 ?

Once we have verified access to the system we continue - with the thought to check what is installed, clean up and then install the 304 driver from our repository .

should be

no big deal

[mc4man]

Just a thought - it seems login was fine before installing the 375 drivers so maybe remove, reboot & take from there, i.e. from tty
sudo apt purge nvidia*

It runs.
I did all your scripts that U wrote.

Once we have verified access to the system we continue - with the thought to check what is installed, clean up and then install the 304 driver from our repository .

should be
no big deal

Once I've finished -with apt get update, and upgrade-, I reboot. I see the Login interface, at this step I could not login,-with ctrl +alt+f1 worked in anyway-, but the goal with is to connect with its powerful GUI.
