I'm slowly giving up on it these days. From
GRUB problems, to having to recompile ALSA everything & editing the alsa config file to have audio working (over spdif), to Hardy Heron freezing solid on the kids box pretty much daily (I tend to blame the ati drivers for that one -- too bad it's not windows, no minidumps to check!), a LOT of flickering of the screen on some stuff like supertux which one of my daughters likes a lot (ATI again) -- thankfully it runs great on Windows, and sometimes sound doesn't work at all until you reboot (probably something with the SB live 5.1 having problems with the newly adopted Pulse Audio) but it's hardly surprising when you know
how much of a mess Linux audio is, power saving not working nearly as smooth as Windows' on that box (pretty annoying), numerous issues with Hardy Heron in general that I didn't have with 7.10: Network Manager sucks, the update manager saying its up to date when sometimes it isn't, not coming with the tools to create network shares anymore (install nautilus-share, then reboot, and to change workgroup name, you again have to edit the samba config file by hand), not having the most interesting options of compiz fusion enabled by default, nor having the app to configure it installed by default, etc.
So 2 of my boxes are no longer dual booting... I just don't have the time to try another dozen distros, learn all the specific quirks those have, and all the necessary workarounds/fixes. Windows
just works on these boxes, all the time, reliably. No crashes, freezes, strange problems or anything... Linux only seems to bring you
different problems (and more of them from what I've seen).
