My personal experience with drivers being updated (say, along with the kernel) is that X keeps running but if I try to restart it then it won't work unless I reboot which is understandable considering they are now linked against new kernel. Perhaps a similar thing is happening here, big driver update. I think you should say what your DE/DM is, I thought those never get restarted by default. -- Mateusz K. _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
