I have installed ubuntu 12.04 on my laptop. I also have win 7. the thing is I can only boot into both when I change graphics settings in the BIOS menu and I have to make it integrated. If I have it on switchable, when I try and boot into ubuntu, it shows a purple blank screen for a little while then screen goes blank. If I change it to integrated, I can boot into ubuntu fine and everything works. I don't want to keep going to the BIOS menu and changing it for ubuntu, I wish to leave it on switchable so that I can boot into windows and ubuntu. Also there is no problem when I try to boot into windows when it is on integrated but I want to boot into windows and use my dedicated graphics not, the integrated one.
I have a acer aspire 5750G, the dedicated Graphics card on it is a NVIDIA GeForce GT 520M. How can I make it so that I leave it on switchable and I can boot into ubuntu.
thanks for any help !!
