After installing Hardy Heron RC1, I found that my NVidia driver was no longer working. After hours of pain, I found the following solution to work easily.
- Go to System -> Administration -> Synaptic Package Manager
- Search for envyng and select envyng-core and envyng-gtk
- Apply
- Close the Package Manager
- From the command line, runĀ envyng -g
- Use the auto-detect option
- Restart the computer when prompted
- If your display is still messed up:
- Open a Terminal
- sudo /usr/bin/nvidia-settings
- Click X Server Display Configuration
- Save (it will write a new xorg.conf file)
- Restert the X Server ( Ctrl-Alt-Backspace )
- Experience the joy of a properly working NVidia driver on Ubuntu

I’ve tried your solution but it does not work for me.
I have an Nvidia Geforce 4 mx440
when I run “sudo /usr/bin/nvidia-settings” it says
ERROR: the control display is undefined. please run `nvidia-settings –help` for usage information
I’m a beginner with linux!
Any idea?
Thank you!
Hi,
tried this solution after many other attempts. Worked like a charm. THANX!
Yes dude, this is very nice, fixed my problem with hardy dual head, compiz. nvidia.
Huzzah, thanks for this. worked like a charm. I too have the MX440 and was stuck at 800×600.
For anyone else that is struggling with this problem, another handy tip is that you can move any window around with the mouse if you hold the alt key and just drag it (very handy when the window doesn’t fit on the screen).
This is the first time it has ever worked, and I tried a *lot* of suggestions these last few months but each time Hardy refused to recognise the drive.
This solution worked first time. I am using GeFore 7600 with an AMD64 4200 dual core.
Many thanks!
I’ve been frustated to get my Geforce 4 MX440 work with many other tips….
