How do I check the screen adapters etc?

System Settings->Software & Updates->Additional Drivers

To check what graphics adapter:

sudo lshw -C display

Should result in something like this:

sudo lshw -C display
[sudo] password for cariboo:

Display with Ubuntu 15.04 on has been giving me fits. My display adapter is
description: VGA compatible controller
product: 4 Series Chipset Integrated Graphics Controller
vendor: Intel Corporation

After 11 months of hassle a workaround was posted on Launchpad:

#sudo nano /usr/share/X11/xorg.conf.d/20-intel.conf
#Add the following lines
Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
Option "AccelMethod" "uxa"
EndSection
#reboot

Default AccelMethod is called "sna" which code is screwed up on this Lenovo M58p.

I'm guessing this might be worth a try for you......no promises.

I think VinDSL posted this a couple of years ago, I think it was during the saucy dev cycle.
But I can't find the link. Worked Nice on Acer 5560 and Lenovo B-570
