Try this solution proposed by dromnia86 on

It worked nicely for my machine.

# Create the file 20-intel.conf in /usr/share/X11/xorg.conf.d/
sudo nano /usr/share/X11/xorg.conf.d/20-intel.conf

# Paste the following into the file and save it:
Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "AccelMethod"  "uxa"
EndSection

# Restart the machine
# If this plays havok with your brightness on your display, reopen the file and 
change it to:

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "AccelMethod"  "uxa"
EndSection

Section "Device"
    Identifier  "card0"
    Driver      "intel"
    Option      "Backlight"  "intel_backlight"
    BusID       "PCI:0:2:0"
EndSection

His post also talks about a potential solution for screen blanking after
waking from suspend, so check it out if that affects you too.

I hope this helps.
