Nvidia Drivers Issue (startx) - detailed info inside - please help!

Hello community,
I'm (almost) ready to throw my laptop off a really tall building, because I'm that pissed off and can't seem to find my way around to solve this problem.. And it's a good laptop, with i7 top notch processor, so that just goes to show how hopeless I am.. :/

Okay, joking aside I really need your help! I think I've spent last 2 days installing/uninstalling BT5r3 numerious times and tried many different ways around installing nvidia drivers but none seemed to work..

This is the case: I have Dell laptop N5110 with GeForce 525M graphics card. It's optimus tehnology, meaning I have 2 graphics card, Inter HD and GeForce, and it should change them depending on what I'm doing on laptop..

I did a clean install of BT5r3-64x off USB pen installation, and did the following:

1. typed: prepare-kernel-source
2. typed: cd /usr/src/linux
3. typed: cp -rf include/generated/* include/linux/
4. downloaded (either 310.19 or 304.64, can't really remember, 64x edition) driver from www.nvidia.com/object/unix.html
5. typed: chmod -x /path-to-downloaded-run-file

then I went on to disable nouveau kernel
1. opened grub.cfg with gedit /boot/grub/grub.cfg
2. searched for vga=791 and appended "nouveau.modeset=0"

Then I rebooted..

Next, after I've logged in, without typing "Startx" I did the following:
1. cd /path-to-driver
2. ./driver-name.run --kernel-source-path='/usr/src/linux'
3. then the installation did its own thing
4. then i updated the grub with command update-grub
and then I rebooted again..

When I tried to wrote startx, I was greeted with this:
Attachment 1205

And I have also included the Xorg.0.log file in attachments..

Well, first of all, you should never touch the grub.cfg file, this is generated by update-grub. Any alteration to it, must be done using /etc/default/grub and /etc/grub.d scripts.
Second, I do not see where you are uninstalling and blacklisting nouveau driver.
Third, propietary nvidia driver does not handle kms (Kernel Mode Setting), that is why you are setting the modeset = 0, but when you are using noveau, in which case is not very recomended unless you have video issues.
Fourth, you first do step 2 (Second reason).

If you have no screens found, you might want to modify the xorg.conf in the Monitor section and add the pci slot id where vga card is located..But after doing all of the above and only if "npo screen found" error appears....

Luck

Hey maverik35,

First off, thank you very much!

Secondly, could you be more specific about the steps I need to take in order to make it work? :/
By reading your post it seems like you know what you're doing, and I'll be really happy if you could sit down (when you have time) and give me a more detailed how-to, since I really don't know how to fix this one, on my own.. :

Thank you once again!
