First of all, I have checked a lot of similar topics, but I still can't get my laptop to use Nvidia 740M.
So first things first.
I have a laptop Asus X550V (i5-3230, 4gb RAM, Nvidia 740M + Intel HD4000). I installed Ubuntu 13.10 alongside Win8 (preinstalled) and both systems are running without problems. However, I have problem with second graphic card (Nvidia 740M), as Ubuntu doesn't recognize it. I installed bumblebee with this tutorial, but I still get error
Cannot access secondary GPU" error when trying to run ''optirun Steam'' in terminal.
Then I tried to do this:
[ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected. you need to edit the /etc/bumblebee/xorg.conf.nvidia (or /etc/bumblebee/xorg.conf.nouveau if using the noveau driver) and specify the correct BusID by following the instructions therein.
But with lspci / VGA i get only info about Intel 4000, but no Nvidia. When I type only lspci, I get the line for Nvidia 740M, but after I edit the config file I still get second card error.
/etc/bumblebee/xorg.conf.nvidia there wasn't BusID or anything similar, so I just added the whole line in device section.
As I said, I tried a lot of things to get it working, avoiding this forum (as I didn't want to bother people with some solutions possible), but alas!, I had to bother you.
If there is a need for some additional info, just say, no problem at all.
Thank you very much in advance. :)
