Current Setup Two schools have 6 seat setups with 1
computer System has problems registering and there
is no audio

Issues with Current Setup Keyboards are assigned to wrong Screen Mice are clicked out of order USB cables when unplugged cause
system to become confused

Deliverables Automated Association of
Monitor Keyboard Mouse
Integrate Audio at each station

Conceptual Designs - Software Linux (Ubuntu)
MDM (Multi-seat Display Manager) GDM (GNOME Display Manager) Userful (Commercial Software)
![Page 11: Time-Sharing Computer System with Sound Management Proposal](https://reader035.fdocuments.net/reader035/viewer/2022081421/5681677f550346895ddc88a8/html5/thumbnails/11.jpg)
Multi-seat Display Manager Specifically designed for multiple seats Runs nested, virtual sessions Pros
Free Currently being used in Tanzania
Cons Less support Easy for users to make mistakes

GNOME Display Manager Current Ubuntu configuration Multiple user system Pros
Inexpensive Common display manager
Cons Not currently used in Tanzania Not designed for more than two seats
![Page 13: Time-Sharing Computer System with Sound Management Proposal](https://reader035.fdocuments.net/reader035/viewer/2022081421/5681677f550346895ddc88a8/html5/thumbnails/13.jpg)
Userful Commercial software Designed for up to 10 seats Pros
It does everything! Solves audio problem Solves automation problem
Cons Cannot alter configuration files More expensive (roughly 35% per seat)
![Page 14: Time-Sharing Computer System with Sound Management Proposal](https://reader035.fdocuments.net/reader035/viewer/2022081421/5681677f550346895ddc88a8/html5/thumbnails/14.jpg)
Conceptual Designs - Hardware Automated USB Hub Device will perform automatic
registration for Keyboard, Mouse and Sound
May require additional custom software Will not be needed with Userful solution

Cost Analysis - Per Seat
Software USB
audio USB hub Enclosure
Total
Software USB hub with
audio
Total = $69
MDM Userful
- Free- $20- $20- $5 = $45

Cost Savings Comparing MDM and Userful
$24 saved per seat x 6 seats per school = $144
3 schools x $144 = $432
If implemented in 100 schools (600 seats) Savings of $14,400
