I'm using Ubuntu 12.10 on an Asus EEEPC 1015PN. This netbook has an Nvidia Ion GPU, which I had to install Mtrons scripts in order to use (located here: https://sites.google.com/site/mtrons/howtos/eeepc-1015pn). These worked great at first and I much prefer the Nvidia mode for Steam and Minecraft and other gaming.
However today I tested out the Intel mode and it also works great. But I restarted in order to go back to the Nvidia mode and it doesn't boot to the window manager, instead it just drops me into
tty1. The only way I can get to a GUI is by using the Intel mode and now I'm basically stuck in Intel mode. I tried restarting many times and also have tried the commands from Mtron's script such as
sudo display-settings auto and
sudo display_settings fix and also
sudo display-settings config-nvidia. None of those worked. I can't seem to get to the GUI. I would appreciate some advice if anyone has encountered this problem. Thank you very much.
