Re: Problems with Additional drivers and Installing graphic drivers
What video card or chip do you have? When you install 12.04 with nvidia video card or chip it usually automatically installs nvidia-current during installation. The x-swat repository can be added if you need most recent nvidia drivers. However, I would not know what to do if you have older nvidia hardware that the current drivers do not support.
The only thing I needed to do to install with GTX 550 Ti was enable nomodeset kernel parameter to boot to a live/install system. But once nvidia-current was automatically installed during installation, I did not need any boot parameters for the installed system and everything works fine.
i5 650 3.2 GHz, 8 GB, nvidia GTX 750 Ti, 32" 1080p | i7-4700MQ, 8 GB, Intel HD 4600/nvidia GTX 765M, 15.6" 1080p | etc.
