[ardour-dev] Ardour doesn't run remotely? (Gdk-ERROR **: BadWindow)

[Mark Knecht]

Hi,
   As a few know I've got a new AMD64 machine that has been giving me
xrun fits. An individual on the Gentoo-users list made the sort of
obvious comment that I should try using the machine in a more headless
mode and run the apps remotely. I did this and now have no xruns even
at 64/2. However I'm finding that a number of my favorite Linux audio
apps do not behave so well when I do this, one of them being Ardour.
Is this caused by my sort of strange setup being both 32-bit and
64-bit machines, different kernels, etc, or is this an Ardour issue?

   NOTE: Ardour is not the only app having trouble, but there are many
apps that work also so it's not a problem that kills all apps.

   Here's what I see:

Down through the Gdk-WARNING messages it's all normal. When the GUI is
up I try clicking on the Session menu and it immediately crashes with
the Gdk-ERROR messages.

   The error messages are repeatable except the 'serial' number changes.

   Maybe this is an ssh config problem?

   I wonder if someone could try this between a couple of their
machines and see if it works for them?

   If you're not set up to forward X then don't forget to change
/etc/ssh/sshd_config to allow X forwarding and to restart sshd.

   Thanks in advance for trying this out. It would be a huge help if I
could run my new machine, even in this slightly strange manner. Heck,
the Ardour machine could be in another room and I could run a thin
client for my desktop...

Cheers,
Mark
