[SOLVED] Screwed up graphics configuration

[swoopdk]

Hi

I really need your help to fix my moms pc.

She have just got a new pc where I installed Ubuntu 8.04. The only thing she complains about is low frame rate. So yesterday I tried to do something about it but I didn't turn out very well.

The issues are now this:

1) The normal Ubuntu / Gnome login screen is now only about 1/4 in size and you can't see the login boxes for user name and password.

2) The resolution in Gnome is a bit better and is almost what it was before I started to fumble around.

3) The frame rate is in fact even lower now than it was before. As far as I remember the current rate is 51 Hz.

Graphics card is an Asus GeForce 8600GT, Monitor is Samsung 20" 2032BW.
One of the things I tried was switching from nvidia-glx-new to xorg-driver-fglrx (naturally I have switched back).
The option "Device driver NVIDIA accelerated graphics driver (latest cards)" is activated.

Thanks a lot for any help to improve the current situation.

Try to compile an Nvidia driver that matches your card, it can be downloaded from their site MAKE SURE TO SELECT THE APPROPRIATE VERSION...

They have a guide about the installation so it will be fine... ^^

I dont think the nvidia driver should be used for asus GeForce?
I am not sure what the default driver in ubuntu will be for GeForce - but I recommend a more compatible driver - cant use a bmw cylinder head on a toyota engine just because they are both 3 litre engines?

try

sudo dpkg-reconfigure -phigh xserver-xorg

then you need to log out user and log in to restart the xserver (you can also crtl+alt+backspace)
This will reconfigure your xserver graphics side of things.

If hers is an old monitor I dont recommend messing with horizontal and vertical sync - this can (only in certain extreme cases) cause damage to the crt - most monitors nowadays have protection built in though.
hope this helps

Geforce is a product of Nvidia...Instead of him using the older version from synaptic, he could compile and use the latest driver..

Asus is the manufacturer of the card and their using the Geforce 8 series chip of nvidia... So if you think the nvidia driver cannot be used on Geforce, will I use the ATI drivers instead?

Thanks a lot guys for your input.

I'll download latest NVIDIA driver http://www.nvidia.com/object/linux_d...173.14.09.html

This should improve the resolution and frame rate. But how can I set the resolution used at the login screen?

for me I would always first make a backup copy before I begin messing with anything

sudo cp -a /etc/X11/xorg.conf /etc/X11/xorg.conf.16jul08 
OR
sudo cp -a /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
OR
sudo cp -a /etc/X11/xorg.conf /etc/X11/xorg.conf.working

OR whatever filenaming convention you want to apply - it is always good to keep consistency and clarity in naming files


then you will need to run that

sudo dpkg-reconfigure -phigh xserver-xorg

or

manually edit the xorg.conf file with either vi, gedit or nano
such as

sudo gedit /etc/X11/xorg.conf

That will automatically generate a new xorg.conf file for you
