Installing Nvidia graphics card in kubuntu 11.04

Re: Installing Nvidia graphics card in kubuntu 11.04

In your original post, you mentioned "on board default graphics" -- is there a graphics chip on the motherboard? If so, does your BIOS give you an option to disable it?

Also, I would like to see the file /etc/X11/xorg.conf which is created by nvidia-xconfig.

Hi...Now i'm able to save the xorg.conf file via nvidia settings manager ...I don't exactly know what i did to make this work....When i started my machine today ...I'm able to save the file...Here goes the current content of xorg.conf file...

home@myworld:~$ sudo cat /etc/X11/xorg.conf

Thank you very much for guiding me out...

Can you please let me know .. how can I test if my graphics card is running fine....

Re: Installing Nvidia graphics card in kubuntu 11.04

Huh -- that's a good ending to a strange situation.

To verify glx is working, open a terminal and enter "glxgears" (as a user). You should see spinning gears, and if you move the window with the gears you'll see that it is listing the frames-per-second rate. glxgears is only useful to verify that glx is enabled -- you can't rely on the fps rate, except to see if it is extraordinarily low, which would indicate trouble running things like google earth.

You can install nvclock and use it to check the temperature of the GPU.

I would not advise a new user to launch a compiz project right away. First enable KDE desktop effects in system-settings, and learn what kwin can do for you, including a "cube". I don't even know whether compiz still works on kubuntu -- there has been quite a lot of development of KDE desktop effects since I last tried compiz, and I've become quite satisfied with the KDE capability.

Re: Installing Nvidia graphics card in kubuntu 11.04

Thanks again for your help on this ... glxgears worked fine..

I have installed nvclock as below

home@myworld:~$ sudo apt-get install nvclock

Also when i gave nvclock in the konsole...i got the below messages...

home@myworld:~$ nvclock

Using NVClock you can overclock your Nvidia videocard under Linux and FreeBSD.
Use this program at your own risk, because it can damage your system!

please share your comments on this..

Thanks

Re: Installing Nvidia graphics card in kubuntu 11.04

Try

sudo nvclock -i

nvclock requires root privilege to run.

man nvclock

will show you other options.

Re: Installing Nvidia graphics card in kubuntu 11.04

I got the below message .. when i tried sudo nvclock -i

home@myworld:~$ sudo nvclock -i
[sudo] password for home:
Unhandled init script entry with id '�' at da0b
Unhandled init script entry with id '�' at da0b
It seems your card isn't officialy supported in NVClock yet.
The reason can be that your card is too new.
If you want to try it anyhow [DANGEROUS], use the option -f to force the setting(s).
NVClock will then assume your card is a 'normal', it might be dangerous on other cards.
Also please email the author the pci_id of the card for further investigation.
[Get that value using the -i option].


Please advise on this...Thanks

Re: Installing Nvidia graphics card in kubuntu 11.04

Suggested packages:
nvidia-glx

That's odd -- I thought nvidia-glx would have been pulled in with the driver. Hmmmmmmm. Unfortunately I don't have a Kubuntu 11.04 installation on Nvidia hardware to confirm. Maybe someone else using the proprietary driver can comment on this -- I am tempted to think you need to install that package, but I don't want you to do it until we can be certain. It may or may not be relevant to your nvclock issue.

Your 8400GS is definitely NOT too new to use nvclock. So this is some kind of problem with your setup. Go ahead and try it with

sudo nvclock -fi

and lets see if it runs the checks.

Also, try this:

sudo apt-get update && sudo apt-get install nvclock-qt

I don't know whether that package is in Kubuntu 11.04 or not.

Not sure with the error message..please advise

Re: Installing Nvidia graphics card in kubuntu 11.04

Try it

sudo nvclock -f -i

I dunno, I've not had that problem.

Re: Installing Nvidia graphics card in kubuntu 11.04

My Lenovo T410 has an nVidia 3100M. I'm using the latest proprietary driver from the X Updates PPA. It works without problems on my laptop, even handling dual monitors and -- gasp -- projectors. By adding the X Updates PPA and installing nvidia-current, you can keep your driver up-to-date.

There is no nvidia-glx package anymore, at least none on my Natty box. There are some nvidia-glx-nnn packages, which all show up as "transitional" because they actually depend on nvidia-current. nvclock's suggestion to install nvidia-glx is more or less a left-over, because nvidia-current now includes GLX capabilities.

I played a bit with nvclock, and it also seems to think my card is too new. "-f -i" gives me a bit of info, but I'm not so sure about its reliability -- for example, it says my card is running at -2147483 MHz. Yes, a negative clock speed!

Re: Installing Nvidia graphics card in kubuntu 11.04

Hey itbal lets go tips

nvidia-settings won’t save xorg.conf in Kubuntu

Just loaded Kubuntu 10.10 and was going through the usual updating system and drivers and such. When I ran into this problem “nvidia-settings can’t write to file /etc/X11/xorg.conf” even while under sudo. I found this odd. The answer actually is in the error nvidia-settings produces in the terminal (if you ran nvidia-settings under terminal) and it says something about “cannot load module gtk”. This makes perfect sense, Kubuntu doesn’t load any GTK modules so you gotta do it yourself. Since nvidia-settings runs under python, you must load the python GTK modules… easy enough!

Is very good tip.

[itbala]

Re: Installing Nvidia graphics card in kubuntu 11.04

You mean to say like .. I must load the python GTK modules first abd then invoke nividia-settings manager...?

If so, Can you please help me loading the python GTK modules as I'm aware about this.....!

Thanks

Re: Installing Nvidia graphics card in kubuntu 11.04

Hi,

I'm facing the same problem again...post reinstalling my OS ... I'm not able to save the xorg.conf file via nividia-settings...

Can someone please help me with loading the python GTK modules to resolve this issue...

I've searched in Internet and would not able find the apt steps to load the python GTK modules...

Thanks

Re: Installing Nvidia graphics card in kubuntu 11.04

Hello!
My 1rst posting here...starts with doubts:
I am curious about that mentioned gtk module to load.
Running 11.04 Kubuntu,nvidia driver,I can run

nvidia-settings

without problems/modules to load.
Delete your current xorg.conf (if there is):

sudo rm /etc/X11/xorg.conf

( You can always create a new one by

sudo nvidia-xconfig

) ...also makes a backup automatically.
then run

nvidia-settings

without kdesu (afaik not necessary in newer driver versions;asks for password when parsing xorg.conf)
Does it again refuse to "Save To X Configuration File"
after you made your settings ?

Re: Installing Nvidia graphics card in kubuntu 11.04

nvidia-settings is a user-space package, same as kate or nano or any other user package. /etc/X11/xorg.conf is a system file, which can only be modified by root (or a user with "sudo" privileges). Therefore, the user can run nvidia-settings and make adjustments in the screen resolution in the current user session. But, to make changes in /etc/X11/xorg.conf, (by pushing the button in the lower right corner of the xserver settings page), it is necessary to run nvidia-settings with a "kdesudo" prefix, in order to give it the super user's ability to write to system files.
