Screen flashes? ubuntu Newbie Series

with 2 comments

After I had installed ubuntu on my laptop, the first problem was my screen flashes severely.

I had tried most ways given in the ubuntuforum.org to fix this problem, editing documents, installing software, but failed.

At last, I remembered a extraordinary simple way referred among hand of complex technical instructions.

Press video output button on your keyboard.

God damn! It works!

No Sound problem –ubuntu Newbie Series

leave a comment »

In Last post I write about how to install ubuntu, and syslik asked help for solving sound problem of his ubuntu.

I am sorry that I reply this help so late, and syslik may has already solved it now. syslik’s trust on me just a little scares me, as he/ she report the hardware data of his computer to me, which making me seems like a master. But I don’t know more than you.

I have found some pages about the sound problem in ubuntu, hope that helps.




Some of the information may be outdate now, but you can find most of the answers in ubuntuforums.org and google.

I have met sound problem too. It’s too low to hear clearly. This is how I solved it.

double click the sound icon on the top of the desktop


then, there’s a mixer


File>>Change Device
choose another available device, and adjust the volume, you can higher your computer sound in this way.

If this cannot solve your problem, try Edit>> Preferences, tick all the possible controls, and try them all.

Good luck!
