I upgraded my laptop to the 64-bit Ubuntu Karmic Koala beta yesterday. For me, Flash was very broken…
The 32-bit Plugin
Ubuntu defaults to installing the 32-bit Adobe Flash plugin and runs it under nspluginwrapper. When I run the plugin this way it will not accept mouse clicks properly. This seems to be a known issue. The bug reports make it sound like disabling compiz fixes this… I don't run compiz, I run the Sawfish window manager. I tested Metacity and it works just fine.
The 64-bit Plugin
Next I tried disabling the 32-bit plugin so that it would use the 64 bit plugin that I already had installed in my
.mozilla directory. Mouse clicks worked… Unfortunately, it was crashing constantly. I couldn't even load gmail without crashing Firefox.
Is it Firefox's Fault?
I have both Firefox 3.0 and 3.5 installed. Both were just as crash happy. I was hoping it would be as simple as blaming Firefox 3.5…
Firefox in a Jaunty chroot
I had a 64-bit Jaunty chroot environment already sitting on my hard drive. It only took a few commands and a little waiting before I had Firefox and the 64 bit Flash plugin from Adobe installed in the chroot. It ran perfectly.
I compared the output of
ldd libflashplayer.so from inside and outside the chroot. One extra library was showing up in the chroot,
How to Fix It
Just install the
sudo apt-get install libadns1
That fixed it for me. As always, your mileage may vary!
