Hi Ed,
Are you running X11 in some mode other than "Millions" Or "From
Display". For example if you have X11 set to run in 256 colors you'll
probably get this error as the GtkWidget won't return a proper visual
(for coot at least).
So to double check do the following:
1) Launch X11.app
2) Preferences -> Output
3) Select "Millions" or "From Display" from the drop down.
Restart X11 (that is completely quit and relaunch).
Then try running Coot again. Let us know if that works.
Regards,
Dave

Thanks for your response Chris.
I should clarify my situation a bit by stating that I'm not trying
to run coot in stereo, I'm just trying to get Coot to run at all.
The error that I get when starting coot prevents me from doing
anything. The odd thing is that this error resembles the one you
got, Chris, when you attempted to run stereo. Unless I unknowingly
set coot to always run in stereo, I'm thinking this problem is
connected to coot starting up and possibly my installed gtk packages.
In either case, Chris, I typed that suggestion in both an xterm and
in the terminal but the problem still persisted. Thanks for trying
though.
Bill, I complied coot myself using fink.
In case I once complied something wrong, I've tried recompiling
coot and gtk+2, gtk+2-dev, gtk+2-shlib, gtk-canvas-dev, and
gtkglarea. That didn't make any difference either.

Edward,
I found the fix for the error message the coot prints out and why
coot won't run in stereo even after updating x11. It turns out
that you have to specifically tell x11 to use stereo
visualization. After updating to x11 version 1.1.3 you need to type:
$ defaults write com.apple.x11 enable_stereo -bool true
(with $ being the prompt)
This will allow x11 to use stereo mode and coot should be able to
switch to stereo mode after this. Hope this helps.

Hi everyone,
I'm having an error similar to Chris Kimberlin but I have not enabled
stereo in coot nor do I get in my error message "WARNING:: switch to
hardware_stereo_mode failed" like Chris does.
This is the exact error message coot prints to my terminal:
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkWidget'
CATASTROPHIC ERROR:: in gl_extras no GtkGL widget!
CATASTROPHIC ERROR:: failed to create Gtk GL widget
The coot startup screen displays, disappears as normal, the tips
screen then pops up but the main window does not. I'm left unable to
quit coot without forcing it to close.
I installed coot 0.1.3-pre-1-138 using fink. I'm running X11 1.1.3
and
Mac OS X 10.4.8.
Curiously enough, I can run coot fine if I remotely log into my
computer via ssh -X and display coot using X11 Forwarding.
Does anyone have an idea how I could get coot running locally again?

For the record, I think (something like) this has been reported
before.
I have not yet tried to reproduce it.
It currently seems to me like a server/driver/hardware error, but
maybe
not.
