Hi Swarnendu, I had the same problem with my Acer Aspire V7-331G with Nvidia Geforce GT 630M card. Yesterday I figured out that my phantom display I've had since 13.10 (both Unity and Gnome) is on and causes the graphics to leave trailing artefacts and slight flickering. I use my built-in display as primary and a external 19" Samsung as secondary. The third display (probably my SVGA with no monitor connected) was enabled but I disabled it and I no longer experienced the flickering and trailing artefacts. This wasn't a problem in 14.04. Head over to Activities > Displays and disable the third monitor if you have one. You might have a slightly different problem, but hopefully this will work if you have the same problem as I did. -- All the best, Bruce FSF Member 10674 / The FSF is a charity with a worldwide mission to advance software freedom / Join the Free Software Foundation: http://www.fsf.org/register_form?referrer=10674 -- Ubuntu-GNOME mailing list Ubuntu-GNOME@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-gnome
