A couple of others that are kind of fun:
xzoom (zoom in and rotate on the screen z to rotate, x to flip x, y to flip y, +/- to zoom, arrows to fine position rectangle)
grafx2 (256 color paint program like deluxepaint, needs package fonts-tuffy)
Some things I've found useful to add to knoppix from debian bullseye packages:
baobab (which you may know as the ubuntu disk usage analyzer)
xdiskusage
ncdu (netcurses text mode disk usage analyzer)
simplescreenrecorder
(need simplescreenrecorder_0.4.2-2+b1_i386.deb and
simplescreenrecorder-lib_0.4.2-2+b1_i386.deb)
osdclock (package name is osdclock)
osd_cat (package name is xosd-bin)

I like to work with monitors and ddc:
gddccontrol is useful to control your monitors
ddcutil vcpinfo will tell you what your monitor ddc supports
with read-edid and edid-decode you can do:
sudo get-edid | parse-edid or sudo get-edid | edid-decode to get the EDID for your monitor.
ddccontrol_0.4.4-1.2_i386.deb
ddccontrol-db_20190826-1_all.deb
ddcutil_0.9.9-2_i386.deb
edid-decode_0.1~git20201230.95d81c9-2_i386.deb
gddccontrol_0.4.4-1.2_i386.deb
i2c-tools_4.2-1+b1_i386.deb
libddccontrol0_0.4.4-1.2_i386.deb
libi2c0_4.2-1+b1_i386.deb
read-edid_3.0.2-1.1_i386.deb
usbutils_013-3_i386.deb
One thing I've noticed on some systems is that get-edid sometimes doesn't work, and if you do "sudo modprobe i2c-dev" that will allow "sudo get-edid" to work properly.
