fc17 install nvidia drivers & modeswitch Telstra Bigpond usb modem/memory stick
 
Hi All,

I have two problems - outlined below.


1: Installing drivers for nvidia GeForce GTS 250M. It's on the HCL, but I am not sure exactly how to get / install the drivers. I saw some stuff on the net, not sure if it was up to date, & can spend hours looking for stuff, so it's easier to ask - someone probably knows the answer straight up.

2: Getting my mobile Telstra ( BigPond) usb Modem to work. There is a problem with it mode switching between modem / usb memory stick. Have found a modeswitch package - does anyone have any extra hints on how to do this? This is the output from lsusb:

Thanks in advance for any help.

on fedora the nouveau IS the DEFAULT driver
so when you install the nvidia one you MUST rebuild the boot image
and USE the driver in the fedora repos

and READ and REREAD the install guide on the fedora forum

as to the usb dongle ??
i do not know

however you might want to read over the fedora forum
there might be an answer there

Thanks john for your reply,

I will have a good read of the links you have provided.

Hi John VV,

A couple of questions:

1: Is the dracut cmd the one that rebuilds the boot image?

2: What to do if it all goes wrong ? That is, to set the default to be noveau again, from the grub cmd line?

Thanks for your help.

1- Until you know if its a switchable graphics or optimus laptop, its best not to go trying to install the nVidia drivers.

2- Sometimes using the offical naming can help. 'BigPond Next G Wireless Broadband' is what I think you are trying to use. This might help you out-

yes

this IS 3 commands not just one
( on the old nvidia thread new users were mistaking it for ONE command)
slightly edited
Code:

su -
------ then your root password when asked for -----
-------------------------------
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
-------------------------------
dracut /boot/initramfs-$(uname -r).img $(uname -r)

that is why read and REREAD the guide

but yes if it 100% blows up in your face
the text only boot will be there

but you might have to repeat making the boot image using the install dvd in rescue mode
( might be a good idea to write them down on paper ( yes paper of all things )

Ok thanks again for your replies - I will have to look into it a bit further.

Ok guys, here's what I have done so far:

In terms of whether the video is switchable or not - it didn't say anything about it for that particular GPU,on the documetation on the nvidia website. There was a mention of later GPU's being switchable. I guess that mine isn't.

I followed the instructions for using rpmfusion to update the nvidia driver, but this failed to boot at all, although there is another boot option that does work.

I re-installed fedora 17 with KDE - it wasn't really necessary for the video problem, but I wanted to make sure I had a clean install. The Live CD failed, I had to goto troubleshoot to set a lower graphics mode, then it was fine. I installed all the software I wanted and installed all availble updates.

In terms of trying to alter the existing system, I thought it might be better to have another grub menu option entitled "Fedora 17 Test Nvidia", and alter files, settings etc for that, leaving the existing configuration alone.
There is a tutorial that I have been following:

To keep things simple, I have started with just making the new grub menu option with a different title, but it does exactly the same as the existing fedora 17 option.

The next steps would be to alter this new option by creating a new kernel and img (by copying the existing ones to a new name). Then alter these by whatever means is going to work.

I have found this as an alternative to using using rpmfusion.

This says that the instructions shouldn't be necessary because distributions are encouraged to package their own binaries to acheive the same thing - I take that is what the rpmfusion is.

Also, I have noticed the nvidia-config cmd which wasn't mentioned in the rpmfusion instructions. Maybe this is part of the problem?

Any that is is my plan for now, am interested to hear any thoughts.
