Hi There,
As so many people are having these kind of issue where the display was getting blur line and hang issue for lower systems. The normally ubuntu higher editions are very useful for unknown linux users also.I am using the ubuntu since ubuntu 8 onwards, As am very curious on ubuntu when they releases the new OS.
Every time i will try the new Ubuntu OS on my system it is working fine on my system until the ubuntu 12.10 after that i installed ubuntu 15.10 and 14.04 there i got the this display flickering issue.
I was browsed so many sites for the solution finally i found a a very useful solution from askubuntu Page.
screen blurs as below. after the blur screen sometimes system recovered by window TAB / minimize method but sometimes it freezes after the blur screen and need to restart manually.
I have tried to install updated intel graphics driver but issue still persists.
Below solution worked for me.
If somebody encountered this problem solution that worked for me was to disable SNA hardware acceleration. You can check if it is active running Code in Terminal:
cat /var/log/Xorg.0.log | grep SNA
To disable SNA you need to create /usr/share/X11/xorg.conf.d/ folder (let it be 20-intel.conf) with next lines enter below code
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
and restart xserver (kill X.org process or reboot or ctrl-alt-Backspace).
rebooting worked for me.
Thanks to askubuntu for great supproting to their users :)
