Do you use weak passwords for your linux desktop (user login, disk encryption, etc)?

Reddit - Thu, 2018-02-08 16:40

I've been curious about this for a while. I'm completely anal about password security and multi-factor authentication. With my password manager, I try to generate 40+ character long random passwords whenever possible for all of my online accounts.

But when it comes to my desktop, my password might as well be hunter2

I have to type it to log in, to update packages, to issue commands as root, etc often enough that it would be a pain in the ass to have to type in a long password every time. Because of that, I tend to keep my desktop passwords short and simple. I'm curious if most other users do the same thing, or if you've somehow managed a workflow that lets you use a strong password for your desktop.

Because there's seemingly no way to access a password manager at the disk encryption password prompt or at the desktop login screen.. it doesn't really seem feasible to use a strong password.

I'm surprised there has been no efforts (at least known to me) to integrate some kind of password management into the linux desktop, considering how many linux users are into strong privacy and security. Is anything like that being worked on? Do you guys use crappy passwords for your desktop too?

How I got my 4K monitor working at 60hz in Linux

Reddit - Thu, 2018-02-08 14:38

I just recently got my 'new' Dell P1524Q 4K monitor and as a little surprise, linux didn't give me 4K@60 out of the box, only 4K@30 no matter how I tried.. despite my 1080Ti and DP1.4 cable, which can deliver 8K@60. So, what the hell was going on since monitor specs clearly shows it can do better.

After couple days of googling and testing I finally found reason and recipe to fix it.

Core reason: Monitor EDID information is plain wrong. Xorg gets loads of valid modes, but 3840x2160@60 is not among them as EDID reports lower mode specs that hw is capable of. Running xrandr -q didn't show anything above 30hz for native 3840 resolution. That needed to be fixed.

First, I used cvt command to generate valid modeline for 4K@60 with reduced blank as this monitor didn't seem to work without.

$ cvt -r 3840 2160 60 # 3840x2160 59.97 Hz (CVT 8.29M9-R) hsync: 133.25 kHz; pclk: 533.00 MHz Modeline "3840x2160R" 533.00 3840 3888 3920 4000 2160 2163 2168 2222 +hsync -vsync

Then I generated basic xorg.conf using Nvidia X Server Settings app. There is 'X Server Display Configuration' which allows saving current config. Once that was done, I added couple options to existing sections to override strict EDID-only-modes and made system to accept my custom modeline.

Section "Monitor" Modeline "3840x2160R" 533.00 3840 3888 3920 4000 2160 2163 2168 2222 +hsync -vsync Option "UseEdid" "FALSE" EndSection Section "Device" Option "ModeValidation" "AllowNonEdidModes" EndSection

After save, I logged out and back in - and voilà, 4K@60 and everything on screen moves smoothly again. Hopefully this helps those who are struggling with this same issue.

Why I love Linux so much.

Reddit - Thu, 2018-02-08 14:11

Was going through some old stuff in the garage and found out my old X40 IBM laptop, it had some old Windows XP that was barely running, very slow... Decided to install Debian on it, works like a charm, and fast, too.

Gotta love Linux!

Miller columns on Linux

Reddit - Thu, 2018-02-08 14:01

I think Miller columns are the most useful view for a file manager.

Yet, on Linux only Pantheon Files implement them (although it's extremely buggy).

I wonder why Miller columns don't get a lot of love..?

Open Up the Source Code to Lock Down Your Data

LinuxInsider - Thu, 2018-02-08 14:00
Meaningful security is more than an app or an OS. It's a mindset. Linux security tools by themselves will not make you or anyone more secure. Security requires trade-offs in convenience, so the tools I'll highlight here are not recommended as "daily drivers." Only you can determine your ideal balance point. Perhaps the single greatest strength of Linux is that it is one of the few open source operating systems, and among the most widely developed. "But wait," you might ask, "wouldn't releasing the source code make a system less secure?"
