Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

For some reason, when I connect 1920x1080 monitor (same resolution as laptop's screen) via DVI whole computer appears uber slow - as I am typing it in gedit there is a .6 second delay after each key press before it appears on the screen.

I connect exact same monitor via VGA and all is fast and nice.

I installed 13.04 64 bit on Thinkpad T530 with NVidia NVS 5400M. In BIOS Optimus is disabled.

This is what I see in Details->Graphics:

  • Driver: Intel Ivybridge Mobile

  • Experience: Standard
