After manually installing Nvidia drivers (downloading nvidia .run driver)

Laptop model - dell inspiron 14 3421

Video card - NVIDIA GeForce GT 625M

I could still access the side bar(unity)/

Here's what I did

1080  sudo service lightdm stop
1081  vi install.txt 
1082  sudo init 3
1083  ./NVIDIA-Linux-x86_64-331.49.run 
1084  sudo ./NVIDIA-Linux-x86_64-331.49.run 
1085  ls -l
1086  vi install.txt 
1087  sudo service start lightdm
1088  sudo start lightdm


  1. Whenever I switch windows (ctrl+arrow keys) the transition effect is gone
  2. ALT+TAB Window preview is missing

Need help guys!

lspci | grep vga
results: none

There used to be a Intel Chipset returned here before I installed the NVidia driver

Here's some additional info. Hope this helps.

jiii@jiii-jump:~$ lspci -nn |egrep "VGA|Display" 00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09)

What hardware is this on? Is it a laptop or desktop? If it is a laptop, is it Optimus enabled? –  ChrisR. Apr 7 '14 at 10:47
dude, i'm using a laptop. Should I install nouveau drivers again? –  olleh Apr 7 '14 at 10:54
What laptop? Is it Optimus enabled (Nvidia Optimus)? The laptop manufacturerr and model number would be helpful. –  ChrisR. Apr 7 '14 at 11:10
I'm using a Dell inspiron 14. How do i know if it's Optimus enabled anyway? –  olleh Apr 7 '14 at 14:34
