start problem in Ubuntu in 11.10

What GPU do you use?
Does the system have a make and model?

NVDIA 8600 M-GT.

What you mean with make and model?

Like a Dell Latitude D420 is a make and model of a laptop. Does your system have a model or is it a home build?

Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia

Thanks

It is a home made. " monster fl90"

ok and the output of:

sudo lshw -C display;

It will take a while if your PCI bus is a bit slow (or busy)

Ok, try:

sudo nvidia-xconfig

Then reboot, if you get no desktop then reboot and hold SHIFT then select recovery mode, then select root. You can now run:

sudo rm /etc/X11/xorg.conf; reboot

note the X in X11 is captiatlized.

ok. but when I select root, I could not make back slash / to go to related folder. Do you know how to make it?
thanks

its on the same key as ? on a UK keyboard

I did... but it says can not remover xorg.conf. read only system.
there is another one xorg.conf.backup should I am supposed to delete that one

It does not work either. Is not there a way to do that?
