Description Mike Gilbert gentoo-dev

Changing the hostname while X is running causes any entries in ~/.Xauthority to be rendered invalid. This will cause X clients to lose access to the display.

This seems to be a common/known issue throughout the internet, but I wanted to open a bug to see if anyone has an idea for how to make this work better.

% xauth list
naomi/unix:0  MIT-MAGIC-COOKIE-1  3abfa887b6a166c2d35530217bed7f86
% sudo hostname naomi2
% glxgears
No protocol specified
Error: couldn't open display :0
% sudo hostname naomi 
% glxgears           
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
