I have to sleep now. I will provide more details tomorrow.
I can reproduce this freezing bug consistently and scriptedly in VirtualBox
with a clean Ubuntu Lucid install. Hopefully, the ability to script it will
help to find a fix. Within the vm, running the script, I get these results:
works: ./tt.sh notitlebars 3
freezes: ./tt.sh notitlebars 4
works, but with maybe 10 second delay: ./tt.sh vanilla 30
Then, ssh to the physical Lucid machine, I can only use low numbers, like 2 or
3, for each. (Details later, if wanted.)
Then, successfully run tests with high numbers, like 40 and 50, for each.
Seems like the faster the machine, the less chance of this bug appearing.
Very important to not touch keyboard or click somewhere while script is
running. It injects keystrokes to current window. :) Which reminds me,
you will need to install xdotools, which is very small. sudo aptitude
install xdotools
1. Ubuntu Karmic. python-vte 1:0.22.2-0ubuntu2.1. Terminator 0.95ppa2. Compiz
and Gnome
Hardware is certainly not too slow: 4G RAM on AMD Athlon(tm) 64 X2 Dual Core
Processor 5600+.
2. Ubuntu Lucid. python-vte 1:0.23.5-0ubuntu1.1. Terminator 0.93-0ubuntu1.
Metacity and Gnome
Hardware is somewhere similar, but don't remember details at the moment.
In the meantime, enjoy the script. Let me know of improvements, also.
