If I or the people I'm talking with turn on the camera, my system becomes so sluggish that nothing can be done (I can't even hang up the call). Event after the other party hangs up, the system keeps acting sluggish, with a 1-2 second delay per action (the most affected is the browser, Chrome in this case)

I have a VM with win7 and have made skype calls in Mint, with the VM turned on. The video was awful, like always (it would be awesome if I could fix this too btw), but the weird thing, is that I could hang up and use the browser and all the OS behaved normally after the finishing the call. It continued for hours, with the VM turned on. Then, as soon I shutdown the VM, the browser becomes unusable, like before.

I'm suspecting this is related to the video drivers, i have the optimus option enabled in the BIOS, so the PC will switch to the dedicated graphics when more processing is needed.Looks like when i have the VM turn on and require more graphic resources, skype works almost normally, as it's using the nvidia drivers and hardware. When i shutdown the VM, it has to come back to the integrated graphics, and then all got screw up. I'm providing hardware info to see if someone has some kind of fix, hint or solution for this :)

The version of the nvidia drivers is the 304.88

See the FAILED on the drivers section? I suppose this is from loading the nvidia drivers. It means that when the optimus switch to the integrated drivers is on, it is still using the nvidia ones, and that's why the performance is so crappy. That would explain why the lag didn't happened when the VM was turn on.

Hi shadow_of__soul, welcome to unix.SE. Try to take a little more time clarifying your writing next time. I've gone through and made some changes and I think I've held to what you intended, though some sentences are really unclear. What does this mean: "like I have the optimus option enabled, it worked with the VM turned on, why as more processing is needed, it used the nvidia card i have"? –  drs Jun 18 at 13:16
    
Sorry, i'll be editing the post again, to clarify my problem and why your changes do not reflect what i mean (for example, i didn't run skype under the VM, i run skype in mint with the VM turned on). Thanks for your help anyway ! :) –  shadow_of__soul Jun 18 at 19:19
