emacs comes up with all characters boxes

This blog item not really a publication, just to record a stupid thing. This blog is the easiest place I know to record little workarounds, etc.  It's indexed.  Plus, no harm in others seeing.  And occasionally they tell me better ways to do things.



Recently have been plagued by emacs come up in VNC with all characters looking like boxes.


This requires xfs, the X Font Server, to be reset.



Error Messages in the VNC Logfiles

Last time I went looking for log messages:

How to reset XFS


From IT (months ago)

for future reference, if it happens again, check your vnc log (should be something like ~/.vnc/mipscs587:1.log) for an error like:

Could not init font path element unix/:7100, removing from list!

if you see this, you need to run, as root:

/etc/init.d/xfs restart

then restart your vncserver session
