Re: Weird colors at VNC after changing nvidia driver
I'm curious on what nVidia chipset that you got installed.
You can share that by typing lspci from a text console, just copy the text contents over here. My thought is that the nVidia drivers you're using, that they support your graphics badly. On the nVidia webpage you can check if the chipset really is supported by typing in your chipset model on the dialog boxes. I would not recommend you to directly install from there, since the nVidia graphics driver will break your graphics each time a new kernel upgrade occurs.
So in short, take a look at the nVidia webpage, check if your nVidia graphics chipset is officially supported.
