cvt_modeline_calculator_12 VS linux

OP's approach looks cool but a bit baroque. I'm also hacking around EDID issues and it turns out there's a nice GUI program to decode and (lightly) patch it: https://packages.debian.org/unstable/utils/wxedid

I have to do more involved full EDID reconstruction surgery tho since I need to add DTD entries rather than just change existing ones. So I'm looking at [edid-generator] together with [cvt12]. The latter can calculate xrandr modelines for VESA standard timings that all seem to work with my TV. It adds an option for NTSC timing over regular cvt which is already in Debian.

4) On Xorg, a custom resolution is represented using a "Modeline", which can be manually calculated, or generated using a utility like cvt. There's also a modified version with more advanced options. Then the modeline can be temporarily added using xrandr, or permanently added using /etc/X11/xorg.conf. Though in my experience, the Nvidia driver is a bit picky about adding modelines sometimes, it seems to be more accepting if you add them in xorg.conf instead of xrandr, and also if you add settings documented here to xorg.conf to disable some forms of mode validation.

Instead of using cvt or gtf, I used cvt12 to get get my Modeline. With cvt12, I was able to get a refresh rate of 160. It is 10 frames lower than my monitor's max, but I'm still happy with this solution.

If you haven't jumped ship to Wayland yet, maybe try using the same custom modeline for both screens? IIRC, you generate the modeline with a cvt calculator that supports reduced blanking v2, and then use it with xrandr --newmode , xrandr --addmode , xrandr --output --mode . Those 3 commands will need to be autorun on login, or possibly you could put the modeline in an xorg.conf.d snippet.

As to how I got the "magic" numbers in the first command? It was done via this program: https://github.com/kevinlekiller/cvt_modeline_calculator_12. I ran it like this:

Then you use the cvt tool (https://github.com/kevinlekiller/cvt_modeline_calculator_12) to calculate a new modeline for your monitor (I'm assuming by "custom" refresh rate, you want to overclock your monitor)

FFS predates FreeBSD and is in some capacity supported by all 3 major BSDs. I'm fairly confident that Linux actually supports it through the ufs driver ( https://github.com/torvalds/linux/tree/master/fs/ufs ); whether the use of different names in different places makes it better or worse is an exercise for the reader.

These are a bit easier to see what's going on:

Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

> The original less-than check was deemed incorrect

It was only deemed incorrect because of an information leak. Not because it's a valid use-case for user space to copy smaller portions of *hwrpb into user space. https://github.com/torvalds/linux/commit/21c5977a836e399fc71...

Correct. And the combined work needs to carry the MIT license text and copyright attributions for the MIT software authors. With binary distribution it must also be overt, not hidden in some source code drop, but directly accompanying the binary.

Many people who talk about relicensing never credit the MIT developers or distribute the MIT license text. "Because it's GPL now."

I don't think that you believe that, but many developers do.

Some don't see the need for source code scans for Open Source compliance, because the license.txt says GPL, so it's GPL. Prime example is the Linux kernel. There is code under different licenses in there, but people don't even read https://github.com/torvalds/linux/blob/master/COPYING till the end ("In addition, other licenses may also apply.") and conclude it's simply GPL 2 and nothing else.

Also be aware that sublicensing is not the same as relicensing.

He notoriously hates GNU Emacs, yes.
