I dont see any changes. Should I be running sudo nvidia-xconfig

You can try may get a error though

Hmm. Yeah it said, Using X configuration file: "/etc/X11/xorg.conf". VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf. At least one Device section is required.

The funny thing is, after machine restart it switches back to making the laptop screen sluggish & external monitor fast.

Can you sudo apt-get rm /etc/X11/xorg.conf and reboot, this should make a new file, check your nvidia settings see if the changed. If not open sudo gedit /etc/X11/xorg.conf and post this new one instead of your old one

I have posted the update at the end of the question.

Remove the line Option "AllowEmptyInitialConfiguration" "on"save reboot etc

I did what you said. But the crazy thing is, on reboot the options was re-added automatically. Ans of course I still see one screeen in nvidia-settings.

OK change it to this Option "AllowEmptyInitialConfiguration" "off"

BTW using bumblebee bumblebee-nvidia did not work as well. Now I cant even see the layout. No X Screen options etc.

Ther was a : on the end did you include this

Oops. No. I thought that was a typo. I am reinstalling that now, with : appended.

Never asume typo, run the exact command

Looks like I cant seem to get the settings options back. I did sudo apt-get remove bumblebee bumblebee-nvidia and then ran the exact command & rebooted.

And If I try to select NVidia it just barfs with an empty error dialog box.

OK do sudo apt-get install nvidia-current-updates and see if they come back

Nope. They didnt come back. I rebooted as well. Not sure if it matters but /etc/X11/xorg.conf is also not present.

make it sudo x-xconfig

It says, sudo: x-xconfig: command not found

HA sorry that was a typo sudo nvidia-xconfig

whoa. command not found

sudo: nvidia-xconfig: command not found

only options available are, nvidia-settings & nvidia-detector

OK this must be an effect of bumbleebee remove it sudo apt-get remove --purge bumblebee bumblebee-nvidia: reboot goto software and updates check ehich driver is activated, you want nvidia-current-updates

It never helped anyway did it

nah. i dont think so.

let me remove it

This is the current drivers situation. But the nvidia-settings still is missing the settings stuff.

Dont understand though why is nvidia-xconfig suddenly unavailable.

Use the bottom one it is updated, see if settings come back if not, sudo apt-get sudo apt-get install --reinstall nvidia-settings

I think nvidia-settings was just uninstalled partialy

ok. on it.

sudo apt-get install --reinstall nvidia-settings-updates use this to reinstall instead

nope. that didnt help. the settings window is fubarred

OK sudo apt-get remove --purge nvidia-current-updates nvidia-settings nvidia-settings-updates and reboot

rigtht so I dont see any nvidia settings anymore

my additional drivers diualog box. is point to nvidia-331.38-updates

Good we uninstalled it, chance to novo what ever the french one in the middle and reboot

done.

now change back to the bottom driver , you dont need to reboot, and then open nvidia-settings

damn..still the same issue. no settings panel.

OK Then sudo gedit /etc/X11/xorg.conf and paste all the info from your question xorg.conf in this and save it

huh. I created the file. And then I restarted the machine. The file is deleted!?!

Should I be stopping lightdm

?

no lightdm is the log in screen X 11 is the display serverin this folder sudo nautilus /etc/X11/ Find all the files called xorg.conf.backup and change it to just xorg.conf and see if it dissapeers

Only change 1 if theres more

yeah it is still there.

but that file is empty.

i mean the nely copied over xorg.conf is pempty

seems like the backup was also empty.. there are other xorg.conf.* files though

wait i need to restart

ok. restarted. the empty xorg.conf is present

Paste the info in it

save the file

yeah. ok.

restarted the machine

and of course. the xorg.conf has become empty

i made sure the ocnten was present by doing more /etc/X11/xorg.conf

Will this work sudo dpkg-reconfigure -phigh xserver-xorg

not sure. nothing happened after I put it in the conmsole.

Thats good did it make a xorg.conf or xorg.conf.new

restarted the machine. and the xorg.conf became empty

nope.it dit not craete any such files

Then make a full xorg from the question then reboot

rebooted

the file is not present

Also the gpu-maanger.conf file has the hashes that I had added before rebooting.

You can remove them

I dont understand why this keep happaning sudo apt-get install --reinstall xserver-xorg might help but could potntialy cause issues

hmm.

You can always recover from alive CD there is a trick to keep the same home folder between installs, so you can always, get it back

right.

Would you like to take some time to think about this ? You can review this documentation help.ubuntu.com/community/UbuntuReinstallation about re instillation. It is easy and right now I think this may work and even fix the two display issue, you would have a new install but yopu home folder would be untouched This may be the fastest way as it only take about 20 mins
