Elementary OS Luna - nvidia problems!
 

Hey everybody!
I am (quite) new to the world of linux, but have been trying out a few of the most basic distros (ubuntu-based ones).
I am now using elementary os luna, and i have a problem with installing my nvidia drivers.
I have really been googling my ass off to find this on my own, but without any results that actually worked for me.
So, i have a HP Envy laptop, with a geforce gt 740m, and i have searched nvidias homepage to find out that the up-to-date driver for me would be the 346 driver. I tried it on Linux mint xfce, and i successfully installed it. I had to add the xorg ppa repository of course, and updated it as well, but when i do the same procedure here on my elementary os, i cant reach the login screen after my reboot.

When i use the lspci -vnn command in the terminal, i get this info on my graphics driver:

01:00.0 3D controller [0302]: NVIDIA Corporation GK208M [GeForce GT 740M] [10de:1292] (rev a1)
Subsystem: Hewlett-Packard Company Device [103c:1961]
Flags: fast devsel, IRQ 16
Memory at d2000000 (32-bit, non-prefetchable) [size=16M]
Memory at a0000000 (64-bit, prefetchable) [size=256M]
Memory at b0000000 (64-bit, prefetchable) [size=32M]
I/O ports at 4000 [size=128]
Expansion ROM at b2000000 [disabled] [size=512K]
Capabilities: <access denied>
Kernel modules: nouveau, nvidiafb

I really hope someone knows how to fix my problem.
Thanks in advance!

please list the output of
1. lsmod
2. grep nvidia_drv.so /var/log/Xorg.0.log
3. dpkg -l nvidia*
4. lsmod | grep agp
it seems you have the "nouveau" loaded when you want the proprietary nvidia loaded?. remove with "apt-get remove nouveau" or "apt-get remove xserver-xorg-video-nouveau" and "apt-get autoremove"
a good page http://wiki.ubuntuusers.de/Grafikkarten/Nvidia/nvidia

Hello and thanks for the faast reply.
As i said, i'm quite new to linux so i'll try my best here to follow your commands.
I also have to say that i have a fresh install of the eos luna, and have done nothing but installed the software updates.
When i click the "Additional drivers" in the system settings, its all empty. Hope this helps understanding my situation.

i wrote "lsmod" in the terminal and got this:

i visited the link you gave me, and it's in german. Im swedish :) But thank you anyway.

I wrote a reply like 15min ago, but it doesn't seem to show up, so i'll try again.
I forgot to mention that after this problem with the graphics drivers, i made a fresh install of eos luna, which i am using now, and i have done nothing but installing the software updated.
When i go to "Additional drivers" inside System settings, and theres nothing there.

Shortly, the only thing i want to do is to update my graphics driver to the newest up-to-date nvidia-driver (which would be 346 i guess)

I visited the link u gave me, but its in german, and im swedish :)
Hope this info is any help.
Thanks

please, show the outputs.
And for sweden neightbours.. https://help.ubuntu.com/community/Bi...erHowto/Nvidia

Hey again!
Thanks again for the reply.
If i write "lsmod" only in the terminal, i get a really long list, do you want to read it all?
when i write any of the other commands u gave me, nothing happens :( maybe im doing it wrong? i just copied them from you here and pasted them into the terminal.
I visited the link u gave me, and have not yet tried any of the commands though im afraid i will screw things up again

andreas@andreas-linux:~$ lsmod

fine: it show the "nouveau" driver is loaded. You have to remove it ans install the nvidia driver manually.
So, follow the instructions of the english link starting with
sudo apt-get --purge remove xserver-xorg-video-nouveau
sudo apt-get install nvidia-346 (load the nvidia-graphics-drivers-346?)
etc.

Okay this makes sense.
I just wrote the command sudo apt-get --purge remove xserver-xorg-video-nouveau, and completed it.
Should i add the ppa:xorg-edgers/ppa and update it before trying the sudo apt-get install nvidia-346 command?
Should i make a reboot right now after i purged the nouveau?
Sorry for all the questions, i guess i could find these answers on my own somewhere else, but it feels safer talking to someone who knows what he's doing.
And i also have a question about bumblebee, would it be wrong of me to install that driver instead? Im going to try to get some games up and running on this system.
Big thanks dude

1. I would do it and ... read read read the english link !
2. no, I would not restart
3. I dont know bumblebee
Generally: you will not kill anything. The only effect you will have with not loading the driver is you will be in text mode.

Hello again!
Sorry for my incompetence with linux :(
I followed the procedure, and it seems that my biggest problem right now is that i cant get rid of nouveau.
I wrote the purge command, and then installed the nvidia-346, but then my computer wont go to the login screen, im stuck at the tty screen. If i remove the installed nvidia-346, i can log back in, but i still have the nouveau driver there. When i try to remove nouveau again, it says it cant find the package "nouveau". I even tried blacklisting it, without success.

When i use the command lspci -vnn, it says that nouveau and nvidiafb is my active kernel.
And when i use the command lsmod, i still see nouveau in the same places as before.

How long did you wait? I remember doing this on one of the Ubuntu derivs, it is actually searching in the background but no indication is given that this is happening, at least as far as I recall. Go to the Additional Drivers and let it go for several minutes and eventually the different driver options should show in the window. If that doesn't work, you'll have a more complicated process.

It sounds good.
The driver can be seen in lsmod?
Then hou have started sudo nvidia-xconfig ?
Installing a driver is a good thing (get rid of nouveau with blacklisting etc.).
But the setup has to be done in order to make the desktop environment working.
Loading a driver is NOT enough.
So, look few advices in the internet how to configure a nvidia card with a loaded driver.
