Hi there,

I am using Ubuntu 12.04 and recently (for about 10 days now) my computer started giving me a purple screen instead of the normal log on screen (where you input username and password). It still plays the short bongo sound. I think that I can normally put my password and continue but the screen never changes from the purple one I get.

Note that this does not happen always. I just switch the laptop off and back on again and usually things work fine. Sometimes I need to do that more than once.

Could anybody help me with that?

Thanks!

Can you give more details about your hardware and the graphics card you have? What graphics driver do you use? Is this an upgrade or fresh install?

Thank you for your answer.

This is what
lspci -v gave me. I am not sure how to get the version of the graphics card driver. I use the one that was automatically installed with 12.04. I run an upgrade but it worked fine since April. It only started giving me this problem now. Maybe some driver update gave the problem?
