I think I know more about the cause of the problem. It is the speaker and conflict with the graphics. I did some more research on this issue and even though I ignored the askubuntu entries on speaker noise, I read it more carefully. It is actually speaker noise that is causing the problem. It is the left speaker which is near the usb port. I had to lift up the laptop and hold my ear next to the speaker to verify it was the speaker and not something else. It is the speaker.
There were some entries on ask ubuntu and http://askubuntu.com/questions/160882/popping-noise-from-laptop-speakers/217334#217334 I tried the stuff here, but the power save stuff did not work in solving the problem. the last entry mentioned some type of hunch about a driver not being loaded and how to verify this http://askubuntu.com/questions/550083/weird-noise-from-left-headphone I do not have the nouveau loaded when I do a lsmod as suggested. This is related to the Nvidia card and a conflict. So I have another card.. intel and this driver is conflicting it. This was said to be fixed, but popped up again from one of the linux guys. I think it is the same problem but for a different driver. I can verify this is speaker noise also by opening wine (and speficially a program called balabolka) and then the clicking starts. If I mute the speaker, then I can remove the noise. This is not a good fix, but it works. In any case, this must be the problem because it is related to the graphics and the speaker conflict. It must be it. I can manually load the Noveau with modprobe but I do not know how to check the kernel for errors. I do not know how to do the commands they say. Here it is the text below: Your DDX does not work with your current kernel and/or libdrm. There are at least three possible reasons for this: the nouveau DRM kernel module is not loaded, a version mismatch between the Nouveau DRM and libdrm, or KMS being disabled. First check, that lsmod command lists nouveau. If not, do modprobe nouveau to load the nouveau DRM kernel module, and check the kernel log for possible errors. If the kernel module nouveau is loaded according to lsmod command, but there are no kernel messages about nouveau at all, then most likely Nouveau KMS is disabled. This prevents the driver to work at all. Possible places to disable KMS are: kernel command line with: nomodeset, drm.modeset=0, nouveau.modeset=0 or similar modprobe.conf or modprobe.d/ adding the module options drm modeset=0 or nouveau modeset=0 initramfs carrying the above module options Check and remove all those that you may find, and retry.
