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?

I get flickering on startup sometimes. I haven't had any data loss or anything like that.

This fix from the Ubuntu Forums might work for you.

Try the nomodeset kernel parameter. In my case it solves the flicker and graphic madness ;)

Here my complete grub line for the kernel: linux /boot/vmlinuz-2.6.32-10-generic root=/dev/mapper/vg-lucid ro quiet splash nomodeset
