How well do laptops with Nvidia Optimus work?
Today I tried to install the Nvidia driver ( from their website) for my Nvidia GT520M on my 11.10 ubuntu. I have stop lightdm so as to not have the " Xserver problem message" and the install was good but now when I restart my laptop, i don't have the normal colors and cases to put my password but only text in black and white.. like "
*Starting anac(h)ronistic cron anacron [OK]
*Starting deferred execution scheduler atd [OK]
*Starting periodic command scheduler crond [OK]
*Checking battery state... [OK]
*Running local boot scripts (/etc/rc.local) [OK] "
Could anyone help me please?
EDIT : Thank you for your link !
But now I make a " sudo sh NVIDIA.run --uninstall" so as to uninstall the driver I installed today and the problem is that I don't have anything after the violet page with " UBUNTU" and the orange&white points.. I only have a blackscreen & ctrl+alt+fX doesnt work
Do anyone have an idea to fix it or am I obliged to reinstall ubuntu?
