After I updated my Linux kernel this morning, my computer no longer boots up with the NVIDIA logo, and instead with an Intel one. I updated my drivers and rebooted, still had the same problem. The computer now runs at a lower resolution, and I can't see the sidebar with applications, or the context menu at the top of the screen. My computer is basically unusable with Ubuntu right now. I'm quite sure that this problem does not have to do just with the drivers.
