Problem installing nvidia drivers - 12.10

[Juniorr]

Sorry for the title but somehow everything got screwed after driver installation on 12.10.

[MG&TL]

Something broke the window manager.

I see you've got some terminals open. What happens if you run

compiz --replace

and

/usr/lib/nux/unity_support_test -p

?

Do you have the kernel headers to match your kernel version installed ?

If I recall, they may not be installed by default in 12.10.

PS. Thread title changed to reflect subject.

I did

sudo apt-get remove --purge nvidia*

and it got back to normal, with nouveau drivers. Then I tried once more installing the 310 experimental driver and got a resolution of 640x480. Once again tried to purge nvidia and now I can't change my monitor resolution hehehe

@MG&TL: Output said "OK" in green to everything.

@howefield: I have no idea what you're talking about

I will do a fresh install, can you give me tips so this situation doesn't happen again?

@howefield: I have no idea what you're talking about

I just booted into 12.10 to get the same issue

Having updated to a newer kernel, without the appropriate headers but a simple matter of installing them sorted it.

Don't know if I have caught you before you reinstall or not,..

Once installed and fully updated open a terminal and type

uname -a

to get the kernel version that you are using. In the attached screenshot you can see that I have

3.5.0-24-generic

I use synaptic package manager so after loading it I'll search for 3.5.0-24 and install linux-headers-3.5.0-24-generic, then install the nvidia drivers and you should be good.

This may well be the case every time you update the kernel, you'll need to update the appropriate headers.

I guess this is the current bug on, possibly 12.10 will EOL before anything resolved

Incorrect resolution and glx errors... this also happens when a user tries to install the nvidia driver on an Optimus laptop.

@OP: give output of:

lspci | grep -i VGA

@howefield: Mine's 3.5.0-25, so can I just install the headers on Software Center?

@mac4man: Would that command install the appropriate headers for my current kernel?

@temujin: I have a fresh install of 12.10, what does that command do and how does it affect on a install with no proprietary drivers?

@howefield: Mine's 3.5.0-25, so can I just install the headers on Software Center?

I don't use the Software Centre, so not sure on that, but you can open a terminal and type

sudo apt-get install linux-headers-3.5.0-25-generic

If they are already installed it will tell you, if not it will install them plus any dependencies.

[Juniorr]

Yes, it said 13.1MB needed to be downloaded. I'll do it, and then install the driver. Do I need to reboot after these headers install?
