And the way to do this right is to have the kernel merely log the error as usual. The user can have some daemon listening to the log, this program may then pop up error messages with nifty detailed explanations, start up diagnostic software for various subsystems and so on.
The kernel can't do GUI stuff - a GUI may or may not be present, and the kernel cannot know. The server may not run X at all but I still run graphical SW on it using a workstation or X-terminal. Or the pc may have three video cards, each running a different xserver with different users for each. Who to report to?
An error-reporting daemon have an easier job, it can look up the correct (possibly remote) display in its config file for all those cases when there isn't just _one_ display.
