MSI notebooks using Ubuntu is facing screen flickering issue for some minutes adter log in. I have tried many things to fix it. But seems the issue unresolved. But it is observed that when a flickering issue occurs, if you click on the right side of the taskbar, where your user name shows and clicking on it will pop up shutdown/ log off like options. If you clcik there and leave the pull down menu there for some seconds, you can see flickering stops. Try it. I hope this will fix it.
I have recently upgraded to Ubuntu Lucid beta version. It is noticed that screen flickering issue is not present in this version.
