Latest Linux 5.11 on an 100 MHz "486" – AMD 5x85 "486" w/ 32MB RAM!

With some optimizations, improvements and fixes, I got latest t2/linux w/ kernel 5.11 running in a 486-class AMD 5x86 and later Cyrix Instead 5x86 (w/o cupid!). It is swapping a bit to death, guess I need to find more and larger memory DIMMs ¯\\_(ツ)_/¯ Mostly to test pata_legacy; and obviously optimizations ;-)

Missing refresh rate in Xorg with RX 6800

I was lucky enough to procure an RX 6800 earlier this year, I was super excited to try out Linux with it, but I have had this issue ever since I installed Linux where it can only choose 120hz max, I have a "Xiaomi Mi Curved 34" which is capable of 3440x1440 @ 144hz.

I have tried Wayland (and Windows 10) and it works fine there so I guess I can just go Wayland, but there are still some hiccups with it in KDE Plasma, so I prefer Xorg for the time being. Do any of you know of a fix or the reason why this is happening? I have changed Display-port cable to 1.4 too.

EDIT: I have checked with xrandr, it says 120hz there aswell.

Debian DWM Autosetup

Greetings,

Recently I wrote a shell noscript to handle setting up a basic install of the Debian setup I want whenever I reinstall it. This is mainly because I have to switch Operating Systems frequently enough for University that it is a bit of pain.

The noscript sets up Xorg and dwm with st as the terminal, dmenu and sxiv as a simple image viewer. Since dwm uses these tools by default, I don't have to do much to set them up either. Still, the noscript could use some cleanup and even a rewrite sometime in the future. But for now, it has worked for me everytime I have needed it.

Any input would be highly valuable.

There are many books written on Linux but personally this book has been worth its weight in gold to me over the years. It's suitable for beginners and experienced Linux users.

How does Mars rover Perseverance which uses linux sync time?

I saw a post saying that Open BSD has added Coordinated Mars Time (MTC). This is an April Fool's joke I think. But it got me wondering since the helicopter uses linux and time is a critical aspect in running command sequences etc. How does it sync time. How much long it would take it to sync time over the network. Do they have some other provisions to sync time? May be this question is silly or not related to linux per se. I am asking out of curiosity. What do you think?

Edit: I was mistaken it is the helicopter that uses linux and not the rover itself.
