This might seem so similar to many other posts regarding Nvidia Optimus Graphic Cards troubles and the pain it inflicts on its Linux users but my question is actually simply how to go back to my last graphical settings rather than how to make my nVidia VGA work.
After facing a complete misery by trying out Bumblebee on my 12.04 machine and having to change my entire OS, I again dared to try it out this time with version 3.0.
Everything was working great, I Enabled my nVidia VGA from BIOS and installed Bumblebee-nvidia. Firstly following the official instructions and then not finding it explanatory enough followed this page guides.
In short not surprisingly it didn't work with errors like:
Bumblebee service is not running and graphic module can't be found but it also left me with a glitchy graphic experience. (As an example hovering the mouse over menu items leaves a trace and highlighting texts specially in bash causes the highlights to overlap creating a mess)
So I reversed every single thing I had done to go back to where I started. Un-installing all the installed packages including bumblebee, nvidia drivers and anything else I had installed according to the guides and in the end disabled my nVidia again from the BIOS.
But the buggy, glitchy, laggy graphic is still with me. I even disabled the open source Intel driver, rebooted and still no success. I am out of ideas.
So my question, above if anyone knows a comprehensive elaborated guide on how to install bumblebee specifically on 12.04 for nVidia and if someone can guess what I have done wrong depriving myself from having a dual VGA experience is:
How to revert my graphic settings to its initial state before the adventure began? Isn't there a sort of System Restore command just like in Windows to go back in time regardless of what you have done?
PS: It could be worthy to mention that before I didn't have any proprietary drivers installed according to the ADDITIONAL DRIVERS control panel but now I have all sorts of open source items there like driver for Bluetooth, mac_hid, REalTec sound card, LPC interface, Intel graphics (which I tried disabling but no change), Intel temperature monitor, HDA driver, USB, etc. It's weird how I didn't need any of these and everything was working perfectly but now all of them showed up there. It would be nice if someone could explain this as well
I just can't afford reinstalling Ubuntu again. Please Help.
