Bug Description
If SLI is enabled, there are many flickering artifacts and double images (especially tooltips). Eventually, the desktop environment locks up completely and the computer needs a forced manual reset. I needed to disable SLI as soon as possible and restart in order to get out of the constant freezing and artifacts.
This issue was not present in 12.04 but became immediately present the first time using 14.04 on the same computer. I know my hardware is not the problem because my video cards work perfectly fine in Windows 8. Bug report and logs below are taken from when SLI is disabled.
