I'd like to point out that the combination of d.title and d.text is not
working also on my system. I don't use the d.* modules much any more,
but after seeing the OP's repeated posts, I decided to try.
I'm using Linux Mint, and here's what I did:
GRASS 7.4.0 (WGS84):~ > g.list rast
srtm_negev_3arc
GRASS 7.4.0 (WGS84):~ > g.region rast=srtm_negev_3arc
GRASS 7.4.0 (WGS84):~ > d.mon wx0 # empty
monitor appears
GRASS 7.4.0 (WGS84):~ > d.rast srtm_negev_3arc # map
displays OK
100%
# Now I try to add a title:
GRASS 7.4.0 (WGS84):~ > d.title -d map=srtm_negev_3arc color=red #
-d flag should display on wx0, but...
GRASS 7.4.0 (WGS84):~ > ERROR: Failed to run command 'd.text

# Another try
GRASS 7.4.0 (WGS84):~ > d.title map=srtm_negev_3arc color=red size=10 |
d.text align=cc
GRASS 7.4.0 (WGS84):~ > # No title appears
# How about text without d.title
GRASS 7.4.0 (WGS84):~ > d.text text="My Title" color=red at=5,5
# Now text appears as expected!
GRASS 7.4.0 (WGS84):~ > echo "Second title" >> my_title.txt
GRASS 7.4.0 (WGS84):~ > d.text input=my_title.txt color=red at=25,25
# Again text appears
# And d.title piped into a file also works:
GRASS 7.4.0 (WGS84):~ > d.title map=srtm_negev_3arc > my_title2.txt
GRASS 7.4.0 (WGS84):~ > cat my_title2.txt
.C black
.S 4.00
LOCATION: WGS84
srtm_negev_3arc in PERMANENT
North: 32.00 South: 29.00
West: 33.00 East: 36.00
Resolution: n-s: 0.00 e-w: 0.00
GRASS 7.4.0 (WGS84):~ > d.text input=my_title2.txt color=red at=75,75
# Text appears as expected
So maybe something is missing/not working in d.title | d.text combination ??

I just want to ask when i run the module d.title it does shown the title
So why the d.title does not work
relevant part taken from the manual:
---
Output created by d.title can be redirected into a file, or piped directly
into d.text to display the map TITLE created by d.title.
---
have you tried d.title + d.text?

Why the module is not working
have you read the manual?
https://grass.osgeo.org/grass74/manuals/d.title.html
d.title generates to standard output a string which can be used by d.text to
draw a TITLE for the raster map layer name in the active display frame on
the graphics monitor. Output created by d.title can be redirected into a
file, or piped directly into d.text to display the map TITLE created by
d.title. The map TITLE created will include the map layer's name, TITLE,
MAPSET, LOCATION_NAME, geographic region boundary coordinates, and cell
resolution. If the -d draw flag is used, then d.title will call d.text for
you and the title will be automatically rendered to the display.
[...]
For example, a user wishing to create a suitable TITLE for the Spearfish, SD
soils map layer and to display this TITLE in the active display frame on the
graphics monitor might type the following:
d.title map=soils color=red size=5 > TITLE.file
d.text < TITLE.file
Alternately, the user might pipe d.title output directly into d.text:
d.title map=soils color=red size=5 | d.text
A file created by d.title can be displayed with d.text. Information
contained in this file takes precedence over the color and size parameters
for d.text.
you need to use d.title in connection with d.text, e.g. on the OSGeo4W cmd
line
d.mon start=wx1
d.rast map=elevation
d.title -d map=elevation color=red size=5
or
d.title map=elevation color=red size=5 | d.text
d.mon stop=wx1
