RAM size shown is incorrect (Debian 9.2) about linux_logo

[aaronfranke]

I decided to do some research on my own. Neofetch, a similar program, grabs memory from /proc/meminfo. Seems simple enough. On my system:

$ cat /proc/meminfo
MemTotal:       16381696 kB
MemFree:         2334052 kB
MemAvailable:    3471604 kB

This should be incredibly easy to pull the info from, it's just string parsing. Here's their code.

My system reads "128TB RAM" with this tool, too, but it only has 16 GB RAM.

Ubuntu 16.04 64-bit.

This is because on recent Linux /proc/iomem is filled with zeros for security reasons.

When I get a chance I'll see what the best alternative to use is.

I wonder what inxi reads to display RAM size? Might be a good place to get ideas.

Confirmed in Slackware -current 64bit (post 14.2).

[TedHartDavis]

Also true on current Arch.

This 128TB RAM bug is also present in Ubuntu 16.04.1 running Linux Logo Version 5.11 using libsysinfo 0.2.1

[deater]

should be fixed with 714bb13

@deater
What is the best and easiest way to access this fix? Should I just wait for Ubuntu packages to update?

@wbraswell The updated version of this package will be included in future versions of Ubuntu, and it definitely will not be added to 16.04.
