For the last month, when starting up or shutting down my laptop under Linux, I would get graphical corruption. Startup has an colour inverted, grainy rendition of what should be displayed while shutdown has a red background with all the text replaced by grey rectangles.
At the very least this affects Fedora, Ubuntu and Xubuntu. Windows is not affected. Outside of startup/shutdown the system is fine.
Should I be worrying about this?
