monitor flickering

rexrugby · 03-27-2008, 02:48 PM

just loaded fedora, kind of have it working. went online etc. but my screen is messed up. it flickers and seems to be sized wrong. the mouse pointer goes beyond the end of the screen. I get an error message that says not optimum mode should be 1680x1050 60hz. those are the settings I have. less resolution makes it fit and stops the flicker but looks bad. I need some help . But i've never done anything in linux before so please be real explicite. Thanks.

What is your graphics card? This problem will occur when you are using the open source driver for newer graphics cards. Both nVidia and ATI have propriorty drivers available for Fedora in the Livna repository. I would check this first.

the graphics card is inboard nvidea 6150SE . what is linna and how would I load a driver?

Go to this link and there are instructions on adding Livna to your repositories for obtaining additional software and updates. If you follow the instructions, it really is quite simple. After you have added Livna to your repositories, your will need to install the driver for your graphics. The instructions for doing all of this is contained in the above link.

Following the Livna instructions for installing the driver for your kernel. It is important that you get that right.

If, after studying the instructions from Livna, you still have questions, return here.

Hope this helps

trying to find the driver for my card. went to nvidia site. looked up GeForce 6150SE/nForce 430 the say nothing availible for 32 bit linux systems. How screwed am I?

BobNutfield · 03-27-2008, 04:22 PM

You are not screwed. A quick google show that your card is supported by the nVidia-96.43 driver. BUT (and an important BUT), do not get the driver from the nVidia site. I give this link once again. Your driver in rpm form (the package manager for Fedora) is there. I am assuming you are using Fedora 8, so just click on the link on the Livna page for instructions on how to get our driver. You may have to ramble around the site a little to find what you are looking for.

By installing from this site, you will be installing the correct driver for your kernel, this is especially important with Fedora.

Open up a terminal and run the appropriate command for your version of Fedora (remember, ONLY PICK ONE):

Code:

wget http://rpm.livna.org/livna-release-8.rpm
wget http://rpm.livna.org/livna-release-7.rpm
wget http://rpm.livna.org/livna-release-6.rpm

Then run (I'll use 8 as an example, replace 8 with 7 or 6 if you are running a different version):

Code:

sudo rpm -Uvh livna-release-8.rpm

Once this is finished, run:

Code:

sudo yum -y install kmod-nvidia
sudo yum -y update
sudo /sbin/init 6

The last command will reboot your system. When it comes back up, you should have better graphics support.

i seem to be having trouble setting up the repository.i download it get a message saying it is already installed. click ok on the message and it gives another message saying no packages were given for installation.

What are you doing to get the error?

Let us know

in terminal I typed the wget line ok but after entering the first sudo line I get a message saying not in sudoer mode and I'm being reported. my first day with linux and I'm already being reported.

rexrugby · 03-27-2008, 05:29 PM

i left out it asked me for a password I tried my root password and my user password nothing types on screen when i type and it doesn't accept either one.

forrestt · 03-27-2008, 05:34 PM

Not to worry, we won't tell anyone.

In the terminal, run the command "su" and enter the root password when prompted. Then run the command "EDITOR=gedit" and then "/usr/sbin/visudo". A window will pop up with your sudoers file. Find the entry "root ALL=(ALL) ALL".

Copy that and paste a copy below the first one. Change the username on the line you just copied to your username.

It should look something like:

Code:

## Next comes the main part: which users can run what software on 
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
## 	user	MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere 
root	ALL=(ALL) 	ALL
rexrugby	ALL=(ALL) 	ALL

And save the file

Of course, if your username is different on your system, use the one on your system. After that, the above commands should work (As well as any other sudo commands you use in the future).

And you will put in your user password, not the root password when prompted by sudo.

after running visudo I get visudo bash command not found

forrestt · 03-27-2008, 05:51 PM

Yes, sorry, I was hoping I updated the instructions before you got them. Run "/usr/sbin/visudo" instead.

that helped but the text displayed didn't have any line with "rootall" in it or anything close to that.
