I am hoping someone may be able to shed some light on an issue that I have been having since installing my new OS.
I am new to the forum, but have been using Ubuntu for a number of years and have a basic knowledge of the OS but this issue has me stuck! So down to business... I have an AMD A6-3620 APU (64bit) with AMD Radeon HD 6530D and I have installed the ATI/AMD proprietary FGLRX driver installed (post released updates installed).
The issue that I am having is that upon start-up once I have logged in I get numerous black horizontal lines flash on the screen. They are consistent and come on as soon as the screen logs in. I have discovered a temporary fix by opening the AMD catalyst control program and changing the refresh rate to 30hrz even though this is the default and what it is set to in the first place... after applying this and clicking OK the lines disappear. I have been doing this every day for several weeks, but although this removes the lines they come back upon reboot and I have to go through the same process.
I hope that someone can make sense of this. Please let me know if you need any further info.
Thanks in advance.
