What do people use for benchmarking under Linux?

mprime (which is the linux version of prime95) for the cpu, badblocks for the disks. iozone is technically "better" for benchmarking disks because it produces actual statistics that you can make lovely graphs with, but badblocks is installed by default and we mostly use it for burnin. But you can get i/o rates out of it.

mprime with the -t option will make your processor sweat big time.

Hey there, sorry I didn't attach pictures or try other photo capturing techniques. I was really tired and passing out in my bed at that point!
So here's what my problem looks like using the gnome screenshot thing.



So this image up above shows the program's display not working. As you can see the visible box in the window's resolution is quite large too.


This is me showing uh, the fix I was directed to by the Arch wiki and I believe essentially what Bourricot asked me to do. So thanks a lot but I think I tried that, editing each comment away one by one until I've tried all the options once. (Leaving the rest commented of course.)


This is just an image of my Gnome on the preferences about thing to prove that I am running gnome 3, which I believe is the gtk3 option in the picture above. To speak to the people talking about my themes. I am using the default Adaita for everything! Except for the shell theme, I'm using no shell theme. As you can see I'm using Wayland. I use GDM I believe, when Arch starts up I'm taken to a graphical user selection screen and log onto the desktop from there. As for graphical driver, just uh, a basic one that does intel built in graphics, arch comes with the vesa drivers, and I just installed xf86-video-intel as a result of the question.

Hey thanks for all the comments, sorry I'm using Arch and making GBS threads up the thread with my problems. Calligra Word still technically works, and I have a desktop and windows. So I'm not totally out of options or desperate or anything. Calligra word just can't really open docx compatibility files however. I'd just like Linux to work and I think of it as a puzzle trying to figure out whats happening and investigating online and stuff. However I'm at a bit of a dead end this time. Thanks for taking the time to read this!

Just looking at your first screenshot maybe it's a hidpi issue

Thanks. I ran mpime on my 3770k and I started sweating before the CPU. IOzone is the thing I'm looking for, if only the results were easier to read. Currently back to phoronix and running the filesystem io tests.



EDIT: I reckon something like the above will be able to give me a good impression of disk io when I fit the new board. I'll do some tweaking of options in the morning to generate a few different set of results with the old hardware.

mprime is so good at cooking processors we have to throttle our systems during burnin or we start flipping breakers.

One could reasonably argue that we should have bought enough power to allow the systems to actually run at full tilt, but we've discovered it's not really necessary. In production the systems almost never get past 80% of their theoretical max (due to i/o waits) so we spec for that instead.

We throw poo poo at Arch because the QA is nonexistent. It "just works" for me, too (if I wanted to use it), but "let's throw some totally untested upstream bullshit at users and hope they can troubleshoot issues they should never have in the first place" is not a great way to learn Linux.

wayland is default on fedora 25 (alpha). It works mostly okay, with some annoying issues and problems (at least from my experience). Not sure if they are gnome's implementation or wayland itself though.
Personally I would probably not recommend it as a default yet, but I see the point of giving it more exposure.

There are Access Control systems that dictate stuff like this. A common one is one that gives users the right to read their own object.

The future five years from now. From what I understand, NVIDIA's drivers are essentially a wrapper around the Windows driver, and the Linux team can't touch the actual driver code. On the other hand, GBM is practically Linux-only, but it's what everyone else uses because it's simple.

This morning, when I was more awake, I notice that

I thought the header contained sensitive information. Surely luksDump should ask for a keyslot passphrase before dumping the header, like it does with adding or deleting a passphrase? :-/

No, and this wouldn't be possible.

However, nvidia ships a "binary blob" as well as their own opengl libraries. Nobody can document how the driver works (or I've never spoken to anybody who does), but oblique comments from people who do know and can't comment due to NDA basically infer that the core parts of the driver (hardware initialization, shaders, etc) are identical on FreeBSD, Linux, and Windows, and that the driver is just a shim to interface with the host kernel.

This is probably ok, but it means that nvidia takes forever to support new features on Linux, and that there may be some dead code paths we can't see. It'd not de novo development

The sensitive bit would be the device master key. Unless you specify the "--dump-master-key" option, the master key will be omitted from the dump... and if you do specify that option, it will ask for a passphrase.

When you use "cryptsetup luksDump" without the --dump-master-key option, the information you get is only what anyone could get by hex dumping the LUKS header block from the disk and decoding it manually. Basically, all of that is information you'll legitimately need to verify the passphrase and start using the disk.

If you count any of the following as sensitive information:
* the fact that the partition is encrypted using LUKS
* the number of active keyslots
* the encryption algorithm used
* the number of iterations you'll need to run the passphrase decryption algorithm for to decrypt the master key, and the salt you need for the decryption

...then you're basically trying to hide the fact that the encrypted volume exists, and that's not something LUKS is designed to do. For that, you would need something similar to TrueCrypt and its hidden-device functionality.

Looks like I forgot to follow up on this. Yes, feel free to blow the unneeded ones away.

If you are using something that compiles extra modules for your kernels without using the DKMS framework, like VirtualBox 5.1, that might be the reason why these get left over: the dpkg packaging system only removes files that it originally put in, and then runs a "rmdir" operation on the respective directories. If there are any extra files in those directories, rmdir will fail and those non-package files and directories will be left as they were.

You could make a script that cleans up the extra non-DKMS modules for a particular kernel, and put the script in /etc/kernel/prerm.d to handle those automatically.
Any script you put in there will be called as:
code:
/etc/kernel/prerm.d/<your script name> <"uname -r" version string of the kernel to be removed>

Ah, yes. Cheers. It would seem that I had assumed that the output of luksDump contained the disk encryption key. From the sample here:



I'd thought that the blocks of hex were the key, but doing a dump again with '--dump-master-key' gives the real key. My lack of attention.

I started playing around with it after reading about the secondary Nuke key built into Kali Linux. It seems like a really cool function to have, but I'm not personally interested in using Kali as a daily driver as I'm not interested in pen testing.

I wonder if the Nuke function's been built into Ubuntu or if there's a general patch that can be applied to any Linux distro?

Edit: Actually. Reading about potential Nuke scenarios (i.e. Handing over a nuke passphrase to someone at border control) just opens up a whole can of worms. Silly idea. I was just being nerdy

From what I can see here, it is just a patch to the cryptsetup utility. The patch looks like it is written for cryptsetup version 1.6.1, so if your distribution uses a different version, you might have to modify it somewhat.

And yes, giving the nuke passphrase at border control sounds like "this person is now classified as suspicious and will receive intensive security checks from this point onwards", if it causes the system to obviously fail.

WTF?

I'm learning a new environment at work that uses GNU bash 3.2.25(1) on RHEL. Occasionally, I'll hit some key that makes bash go into a weird mode where typing isn't normal. It's maybe vi-like, but I can't say for sure. Does anyone know what I'm doing to trigger this mode and what I can do to get out of it? Ideally I'd like to disable that key command, but that probably isn't possible due to permissions.

Without knowing what key combination you hit or how it behaves, this question is unanswerable.

I don't think you accidentally typed "set -o vi", so...
