Unfortunately not.  After going to tty2, entering "killall drracket" and back 
to tty1, the terminal was as I left it, with just the command "drracket" shown 
as the previous command.  I'm happy to check logs, but I'm not sure which 
ones...

It also may be a matter of a library not behaving properly: sometimes my system 
(which runs on a laptop) doesn't wake up properly from a hibernation.  I should 
probably check with a reboot (which I'd rather avoid if possible), or a logout 
from my KDE session and a new login.

I'll do some more fiddlin'... until then it's back to Emacs and Geiser!

After the `killall` from tty2, did the shell you started DrRacket from have any 
output?

Thanks for helping us investigate!

Thanks for the suggestion - which I had in fact tried, to no avail.  DrRacket 
froze, and the only way out of it was via tty2.

If you start DrRacket from the shell, trigger the bad behavior and then
type control-c in the shell, do you get any output?

[racket-users] DrRacket has become unusable: freezes almost immediately

2017-05-23 Thread Alasdair McAndrew 
I have had no problem running DrRacket on linux, under KDE Plasma, until now.  
But now it seems to crash constantly.  All I need to do is:

1. Open it up from the KDE menu
2. Open up the File menu

and then it freezes, and also causes a system freeze, as it appears to be using 
100% of CPU (according to "top").  The only way to recover is to open up tty2, 
and "killall drracket" and then go back to tty1, which on my system is running 
X.  

Does anybody know how to get DrRacket to run again?
