Intel graphics card by any chance?  And... can you still ssh into the machine 
and does dmesg say anything about hangs?

Reason I mention it is it reminds of an intel card bug the intel graphics 
driver guys mentioned a couple of years ago that behaved like that.
Seem to remember they'd added some kind of hangcheck, although we lost 
acceleration after it was triggered. (so a game would drop from 60fps sync to 
like 10fps) - but you might not even have the check.

Or could be something totally different.  Anyway.  Obviously a game shouldn't 
lock up your machine.  So... Sounds like some sort of serious graphics card bug 
that you should be filing against your distro and with Xorg log and dmesg 
included.

Feel free to include that bug report here.

Oh, and, if your card is unusually unreliable, a workaround might be to use a 
non-composited window manager.  XFCE4 for example, or MATE w/ compositing 
disabled.  (that's my general advice to people w/ sucky/unreliable 
cards/drivers, seems to help sometimes, guess helps to give them just one thing 
to focus on)

Hi. Sorry for my late reply.

I recently happened to encounter the same problem with another game, so I guess 
it probably has to be something about the graphics card and/or its drivers.

Interesting enough, the computer I'm using has two graphics cards: One onboard 
Intel and the other PCIx GeForce 8600 GT (It's the computer I'm using at my 
office, which I did not personally configure besides installing Ubuntu and am 
descovering about just now). The GeForce is enabled at BIOS and Intel is not 
enabled (though it is functioning. I checked it). Would an offline Intel 
graphics card cause this kind of problem? Or might it be about GeForce (GeForce 
was used when I encountered the freeze problem)?

Anyway; I see this is not specific to hedgewars. Maybe I'll check it more 
deeply if I find some available time. Thank you for your interest in the topic.

Aight, I'm gonna close this out then.
So, yeah. Check dmesg and Xorg log.

Also, try a different nvidia driver. The nvidia one if on the open source one, 
or vice versa.
And, check for driver updates.

Could also be a failing card.  I had to replace my nvidia card after 5 years of 
service last month due to a failing fan.
