howdy , folks ---
i hope that everyone is well .
in anticipation of installing 10.3 , i have been buying new hardware
[ probably , intel "skylake" and "z170" , of some kind ] .
this new mechanical keyboard , "daskeyboard" ,
with the cherry "blue" switches , is really nice ,
much like that which came with my compaq 486dx , twenty years ago ,
[ which --still-- works and is in use !!! ] ,
even if the manufacturer --is-- too cheap to
put legends on the keycaps
[ before i did any editing , this post looked like
traudl junge's first effort for her new boss ,
in that scene in "downfall" , at the beginning of the film
] .
let me start with the
9.3/amd64/syscons/ps2
box ;
i have not , as yet , installed any new equipment on the
10.2/i386/vt/ps2
box .
if i can identify the solution for these two boxen ,
then all of the others should be "variations on a theme" .
the ps2 keyboards and mice actually have usb interfaces ,
with usb/ps2 adapters , plugged into ps2 ports .
from what i read on wikipedia ,
these should look like ps2 devices to the ps2 ports .
the six_years_old moboes --do-- have usb ports of some kind ,
but this is my first usb equipment ,
therefore , i have no usb experience .
my question is about
cursor_on_screen distance versus mouse_on_pad distance .
the old mice [ mitsumi "roller_ball" ] were kinda slow
[ lotsa pad for little screen ; just fine , otherwise ] ,
but not so much as to be worth whining about .
with this new mouse [ cherry model m-5400/01 optical ] ,
the cursor goes flying , if i just breathe on the mouse .
you know how it goes : power_down , swap kb & m , power_up ;
then , see what's different .
so i start reading [ man_pages , handbook , et_cetera ] ;
eventually , i find the man_page about "/boot/device.hints" .
i find words like "flags" , "resolution" and "acceleration" .
i find an example for "psm0" .
this looks promising .
i check my boot messages ;
psm0: <PS/2 Mouse> irq 12 on atkbdc0
psm0: [GIANT-LOCKED]
psm0: model Intellimouse, device ID 3
these are the same messages as those for
the old mitsumi mouse on the 10.2 box ;
i get the impression that all ps2 mice are pretty much the same .
i note that there are no "flags" ; so i try that .
i "guess" that flags of "0x01" and "0x04" will
disable "acceleration" and
set "resolution" to either extreme , one way or the other .
if this works ,
then i should observe a 8:1 ratio for cursor distance ;
all that i have to do is to pick a "comfortable" setting .
well , that was the plan .
it failed .
let me emphasize : the new hardware --works-- .
it is just that the cursor goes flying across the screen ,
for a small mouse_on_pad motion .
positioning --is-- challenging .
the flags --are-- recognized ; they appear in the boot messages ;
for example ,
psm0: <PS/2 Mouse> flags 0x1 irq 12 on atkbdc0
but the behavior does not change on either the console or the xterm .
maybe the mouse has hardware limitations .
maybe i have mis_identified the correct software module to tweak .
maybe there is some "buzzword" , of which i am unaware .
which ignorance prevents further research by me .
should i be trying to effect this change in "rc.conf" ?
should i be trying to effect this change in "X" ?
[ in re_reading the above , before i send this ,
the thought occurs to me that ,
even if the mouse has only one motion_size ,
scaling --could-- be effected in software , --somewhere-- .
this entire post can be summarized into three words :
"possible" , "where" and "how" .
]
i ask , before i try "something" , because ,
even with all drives backed_up ,
onto drives on --different-- machines ,
none_the_less , i wish to avoid
finding myself in the position of
having to recover from some hardware problem by
turning off the power supply .
although this works , most of the time ,
i --have-- lost a hard_drive this way .
i prefer to not_repeat the experience .
does anyone have any thoughts ?
maybe , someone knows the right leading question to ask me .

ps --- does anyone know how to
turn_off this narrow 65_column auto_wrap
in the "thunderbird" editor ?
