Re: use of graphics characters recently disabled in xterm

2017-09-09 Thread William
I had this (or something similar) happen some years back probably with 
Konsole on an Kubuntu installation. Probably AMD cpu also.


I cannot remember now what I did to fix. Possibly put the characters 
into mc.ini.

I have recently done some upgrades, keeping current with

started to print funny characters around the panels instead of 
printing vertical and horizontal lines. This happens only in an xterm, 
not in the console terminal where all remains OK. The command mc -a 
replaces the straight lines with vertical and horizontal dashes, but 
that does not look nearly so nice.


Oh, I should also say that this happens only on my home machine which 
has an AMD processor and on-board ATI video. It does not happen on the 
machine at my office, which is an Intel CPU with on-board Intel 
graphics. The two machines both run slackware-64-current and as far as 
I know the two machines have exactly the same list of distro packages 
installed.


The only thing I can think of is that something in the options for 
xterm needs to be changed, but I have no clue about what that magic 
option might be. Or, it could possibly be some library which deals 
with graphics and is somehow broken on an AMD-based machine.


I am pretty much guessing, of course, but to fix the problem would be 
nice. Anyone have an idea?

Check your TERM (echo $TERM) variable in xterm. Most probably the 
slackware switched to xterm-256color or something. Also check the output 
of "locale" and check the Ctrl-right click menu in xterm for some font 
settings.

This must have something to do either with your locale settings, or with 
fonts that are used by xterm, but certainly not with the graphics 
libraries or hardware, way too low-level.


In any case, the next debugging step that I would recommend is to create a 
brand new user on your machine, log in as this user in the graphical mode, 
start xterm and try mc. Depending on the results, decide on what to do 
next. The new user can be deleted afterwards with no traces left.
