Graphics drivers, hardware support, graphics platform stability, user experience, software support, community collaboration, these small problems add up to Linux flaws that no one can ignore. These pain points may be the real reason why new users are afraid.

The project received rave reviews on Hacker news, with one user pointing out a common problem with Unix-like systems like Linux: poor user-friendliness and difficulty getting help.

San Kumar solved a big problem: Linux novices couldn't get a solution to the problem efficiently, and the entire tool was implemented in only 100 lines of code.

The same user suggested that this utility should be standard in all future derivatives of Unix-like operating systems.
