I have installed Ubuntu 14.04 on my Lenovo s20-30. This is fresh install. System is quite slow, I thought it may be driver problem. How to check if I'm not missing some drivers or I need to configure?
cichociemny@cichociemny-Lenovo-S20-30:~$ lspci -k | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 0e)
Subsystem: Lenovo Device 3807
Kernel driver in use: i915
lspci -k | grep -EA2 'VGA|3D'
terminal command.
