This is pretty anecdotal I can't say anything for sure, but I'm just 
coming off a long stint of coding in which Geany was open on my machine

once in six or eight hours.  Usually the computer would freeze except 
that the mouse would continue to move, but not have any effect.  
Sometimes the video would go crazy and create a sort of pixilization of 
the screen that looked like those squares you can point your smartphone 
at and order a pizza.  I really had/have no idea who or what was to 
blame, however I've finished coding for the time being and after a week 
with no use of Geany, I've had not a single hang.  Also, after hangs I'd 
often see a file like: '.goutputstream-4BLCY1' which I know is created 
by Geany and not erased in case of some screwup, so it sorta points the 
finger at Geany.  Dunno, is there some way of nailing this down?  Some 
sort of diagnostic or error log or some such that might help?    I've 
reinstalled with no improvement, but that's the Debian repo version.  
Maybe an update?  Pretty thin evidence I know but it begins to look like 
Geany is misbehaving.  I almost wish it happened more than once or twice 
per day because that would make diagnosis easier.  Thots?
You need to look at (several) Linux logs & find timestamps around when your system froze.
Do a web search for "linux (distro name) troubleshoot system problems logs."
Something similar should find which logs to view.
Some, you might have to specify in a CLI to add timestamps to output of the log.

In some distros like (more recent versions) Mint, there's an installed app w/ GUI, called "logs." Go figure.  It shows some but not all entries from several logs w/ some filtering options. If evidence isn't shown in something similar to "logs" app, need to look at full logs.
