Try starting nvidia-settings from a terminal emulator and post the output here in code tags.

Can you show us the output of

$ lspci -v | grep -A 10 NVIDIA

You have an optimus system and are currently running off of the intel chip, see for your available options: https://wiki.archlinux.org/index.php/NVIDIA_Optimus

Re: [SOLVED] NV-CONTROL X extention not found

Ok I was wondering if the right driver was loaded, which seems to be the case. I see that the MX150 is a laptop graphics card, I don't know much about them but I read that there can be issues related to choosing the right GPU to use. Have you looked into that ? This is the post that gave me this hint and seems to maybe have some leads for you to follow : https://bbs.archlinux.org/viewtopic.php?id=244351

EDIT : V1del got me smile

well i am not very expert into these technical things so can you please tell me what does intel only and nvidia only option really means, i also play some games on this device using WINE so what if i choose intel only to save power, does it means in games i won't be abel to use GPU in game ?

Yes, exactly. I think most Optimus users want to use the automatic switching option. That means the Intel GPU is used most of the time to save power, only to hand over graphics processing to the Nvidia GPU if an application requires it (such as a game).
