Problem with sound and graphics

[rythm07devine]

hi,
yesterday i installed Ubuntu 8.04 on my pc with the following configuration.
AMD Athlon X2 6000+
Realtek onboard sound
Nvidia 9500 GT 512 Mb
MOBO: MSI K9N2GM Hyblid SLI
250 Gb HDD

the problem is that the sound is choppy and unbearable..the second problem is that whenever i click on NVIDIA X server setting it shows "You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server. "
i ran the command and configured the display when asked for on restarting Xserver .but the resolution wont get past 800x600 .on restarting xserver.but when i restart my pc and boot into ubuntu the resolution is fine 1024x768.
but NVIDIA X server setting continuously gives me the same msg, and compiz wont work neither emerald.
i have Ubuntu 8.04 installed in my laptop and everything works fine.

one thing I noticed there is no NVIDIA drivers under Hardware drivers. So i downloaded and installed the drivers form their website.

any help will be appreciated
thanks.

You have to edit xorg.conf to specify nvidia driver for your graphics card. Post contents of /etc/X11/xorg.conf file.

the out put is as follows.

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
# sudo dpkg-reconfigure -phigh xserver-xorg

thanks for replyin..and how can i fix the sound problem ...no such problem is there when i am running vista ...but fedora 9 live cd is giving the same problem as ubuntu ..the startup sound is also choppy..

[coopstah13]

you need to replace nv with nvidia in order to be able to use the nvidia proprietary driver, post output of this command too

lspci | grep -i audio

put it inside of the code tags, its much easier to read

[rythm07devine]

the output of the command is :

subhadip@subhadip-desktop:~$ lspci | grep -i audio
00:07.0 Audio device: nVidia Corporation Unknown device 0774 (rev a1)

[coopstah13]

I've read some stuff that says this device has some problems before kernel 2.6.26 I think, and if I remember correctly 2.6.24 is what 8.04 is using. If possible could you try to run the livecd for 9.04 and see if that fixes the audio problem?

[rythm07devine]

yeah thats right .... had Ubuntu 8.10 with me and i installed that and all the sound and graphics problem are gone now ...everything is fine.....
But one small minor problem ..whenever i click on mozilla i get this alert msg

Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.

and then mozilla is exiting after some time ...can anyone help me to fix this issue.
thanks for all the help till now.
