Nvidia GeForce 8200 driver problems on Ubuntu 11.04?

[jxcheng]

I recently installed Ubuntu 11.04 on my Emachine Er1402-05, Wireless works fine, but not the grahics Emachine Er1402-05 has a nVidia GeForce 8200 graphics card.

The problem is that after installation it only support resolution upto 1024x768, while my LCD has native resolution at 1600x900.

I have installed the most recent nvidia driver
$sudo apt-get install nvidia-current

However, I was not able to config it:
$ sudo nvidia-xconfig
sudo: nvidia-xconfig: command not found

I was not able to install the package.
$ sudo apt-get install nvidia-xconfig
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package nvidia-xconfig

Here is relevant info:

$ lspci | grep VGA
02:00.0 VGA compatible controller: nVidia Corporation C77 [GeForce 8200] (rev a2)


Here is the content of my xorg.conf.

$ cat /etc/X11/xorg.conf

Section "Device"
Identifier "Default Device"
Option "NoLogo" "True"
EndSection


Any help would be appreciated.

The nvidia-xconfig is part of the nvidia driver package.
It should be installed into /usr/bin/..
I have never directly used nvidia-xconfig in >2 yrs of nvidia & HTPC.

Have you rebooted/restarted the X server after nvidia install ?
Can you run nvidia-settings (after reboot) ?
Can you select your required screen resolution/video mode ?

glxinfo
vdpauinfo

Post your
/var/log/Xorg.0.log file as an attachment..

Have you rebooted/restarted the X server after nvidia install ?
Yes.

Can you run nvidia-settings (after reboot) ?
Yes. But it gives the warning message: "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."
However, I am not able to install and run nvidia-xconfig
$ sudo nvidia-xconfig
sudo: nvidia-xconfig: command not found

Can you select your required screen resolution/video mode ?
Nope. The highest availbe is 1024x768, while my LCD is 1600x900

Thanks

where is the /var/log/Xorg.0.log file......

So the nvidia X server can not start..

Run this in terminal
dmesg | grep nouveau

Have a search in dmesg output for anything to do with video VGA etc...

[jxcheng]

The following command returns empty:
$ dmesg | grep nouveau

Now I am able to tun the nvidia-xconfig command:
$ sudo nvidia-xconfig
Using X configuration file: "/etc/X11/xorg.conf".

The problem is that I am still stuck with 1024x768 resolution.

[wojox]

Try:

gksudo nvidia-settings

[jxcheng]

I have tried nvidia-settings. However, in the configuration panel, the drop down list of resolution does not go to 1600x900. It does not recognize my LCD monitor correctly, and the max resolution only goes to 1360x768.

[jxcheng]

After I changed the resolution to 1360x768 in nvidia-settings, things gets even worse.
After rebooting, the resolution is changed to 640x480, and I can not go any resolution higher than that.

Please post the file /var/log/Xorg.0.log (as attachment)....

Your video card is not new so any old driver should fine..
You could try using an old driver version like 175.xx.xx..

[jxcheng]

Attached is /var/log/Xorg.0.log .

How do I revert to an older driver version like 175.xx.xx. ?

In the "Additional Drivers" panel, I only see two choices: version 173 and current version for nvidia card.
I am using the current version.
