Reddit: HiDPI laptop with classic 1080p external monitor, can it work?

Tuesday 14th of June 2016 01:41:01 PM


I've already made a thread two days ago about overall hidpi support in linux but I'm going to bother you again, as I found out that multi-dpi settings are a sore point in linux and I could spend all my time on such a setup.

The laptop is a Thinkpad T460S 14' 1440p, the monitors are around 25' 1080p. I will spend most of my working day with the thinkpad as main screen and one or two external monitors.

Here's what I've learned :

  • hidpi settings work well enough in linux

  • but you can't set different DPI for each monitor in X11

  • only workaround I found is using xrandr scale

  • wayland will fix this, but it's not ready for production use yet (and this will be a work laptop, can't have it randomly crash)

So my questions are about the workaround, xrandr scale:

  • First of all, does anyone has experience with this kind of setup?

  • Will scale make the text blurry?

  • Does xrandr scale and xrandr dpi need to restart X, or will I need to close/reopen programs etc... for the changes to take effect

  • What's exactly the difference between setting the dpi and changing the scale? Is the visual result different?

Thanks for your help, sadly I don't have a linux available right now to test all of that myself.

Reddit: Comparison of FOSS Messaging/VOIP Apps (X-Post from /r/opensource)

Tuesday 14th of June 2016 12:23:02 PM

This is a little project that I am doing as more and more FOSS communication tools are popping up. As it could be very subjective (and time consuming!) if I got all of this data myself, it would be appreciated if anyone would be willing to help fill out different boxes in this spreadsheet. The link to the public and editable google sheet is below.


The end goal is to compile a comparison table that can eventually be put onto Wikipedia so that both the general population and more technical users can be more informed when making decisions about using these programs. Any help is much appreciated, and if any creators of these applications have more accurate data, that would help even more. I've already filled out a couple columns to get started, so just copy and paste the check or cross if yes or no, and add additional information if needed (e.g. licensing details). Finally, it would be great if you could log in to google before editing so that I can see who did what.


PS: Cross- posted from /r/opensource to get more people (hopefully!) helping.

Reddit: Wow! Some guy raises a bug called "This feature ain't useful" and Firefox just removes that feature!

Tuesday 14th of June 2016 10:42:01 AM

Today I learned that the freedom and democracy that open source world presents to us isn't without it's pitfalls. I'm a Web Developers and like many devs, I am very dependent on the firefox Developer tools found at the bottom of the browser.

So I was a bit shaken today when I upgraded my Ubuntu and went to Firefox 47, only to find that the font panel in that toolbox is missing! Turns out that some jerk actively raised a bug and requested this feature be disabled:

And his reasoning being:

The font panel is not currently very useful. According to Patrick/telemetry, the average user spends ~5 seconds it in, and it seems like even that might be accidental

As if the telemetry statistics represents the voice of all the users! Seriously, if I go ahead and raise a bug called "Remove feature X", will you just remove it Mozilla?

TuxMachines: BunsenLabs Linux

Tuesday 14th of June 2016 10:17:14 AM

When I first started using BunsenLabs Linux I did not enjoy the experience. At first, it felt like installing Debian with a depressing theme and fewer features. The initial installation and configuration steps felt overly long and complicated. The Openbox environment lacked the features of fuller desktop environments while, at the same time, offering unwanted distractions such as Conky and extra virtual desktops. It would be fair to say the first two or three hours with Bunsen were unpleasant for me.

However, there was definitely a turning point during my trial. Around the start of the second day -- once I had a more colourful theme in place, the Conky packages had been banished and I had got into the habit of installing software I wanted from the application menu -- there was a point where I began to enjoy Bunsen. The distribution's hardware and multimedia support were top notch, performance and the interface's responsiveness were excellent and the applications available all worked properly. Openbox has enough configuration tools to make it flexible without being overwhelming. What really sold me on the distribution though was the way Openbox stayed out of my way, a feature I feel Debian's default desktop does not offer.

At the end of my trial, I still had some mixed feelings. As much as Bunsen grew on me, I couldn't help but feel the experience felt very much like installing Debian and adding the Openbox window manager as a session option. While Bunsen takes care of that step for us, it also adds several extra steps during the initial configuration that made me feel like going with plain Debian and installing Openbox might have been faster and easier.

In the end, I did grow to like Bunsen with its clean, fast user interface. I like the distribution's tweaks to Debian such as adding sudo and providing application menu installers. I think the initial welcome script should probably either be automated or ask all its questions up front and then go to work in the background. It took a while for me to get the interface looking the way I wanted it to and less like the inside of a mine shaft, but once I did the distribution provided a good set of default applications and desktop functionality.

TuxMachines: Leftovers: Gaming

Tuesday 14th of June 2016 10:07:01 AM
  • After a slow start, Dell turns up the dial on Steam Machines

    Dell had high hopes for the Alienware Steam Machine after its delayed release last year, but it did not become as popular as its twin, Alienware Alpha, a Windows-based PC gaming console.

    The viability of Steam Machines, a family of Linux-based PC gaming consoles with SteamOS, has been questioned, but Dell isn't giving up yet. With better hardware and an expanding list of gaming titles, Dell is hoping that interest in Alienware Steam Machines will grow.

  • Dell set to introduce beefed up Steam Machines
  • Platformer On Rusty Trails released on Steam for Linux, some thoughts

    I love the first level of Tiny & Big. It's a massive sandbox 3D platformer area where you get to use tools to slice through and toss around the terrain in order to explore and find secrets. The game quickly gets more action oriented though, and I unfortunately lost interest long before I finished it. Love, Hate & the other ones also looked interesting to me, and I bought and played a couple of the first areas of it. It's a puzzler with interesting mechanics, but it didn't really hook me, and I never wound up playing much of it. That first level of Tiny & Big though had a big impact on me, and I wish I could play a whole game of just that. And it's the creativity and sense of design that went into that one level that made me eager to try the new game the developers have been cooking up since I first heard about it last year.

Five reasons to switch from Windows to Linux

Linux has been in the ascendancy ever since the open source operating system was released, and has been improved and refined over time so that a typical distribution is now a polished and complete package comprising virtually everything the user needs, whether for a server or personal system. Much of the web runs on Linux, and a great many smartphones, and numerous other systems, from the Raspberry Pi to the most powerful supercomputers. So is it time to switch from Windows to Linux? Here are five reasons why. Read more

Security Leftovers

  • Chrome vulnerability lets attackers steal movies from streaming services
    A significant security vulnerability in Google technology that is supposed to protect videos streamed via Google Chrome has been discovered by researchers from the Ben-Gurion University of the Negev Cyber Security Research Center (CSRC) in collaboration with a security researcher from Telekom Innovation Laboratories in Berlin, Germany.
  • Large botnet of CCTV devices knock the snot out of jewelry website
    Researchers have encountered a denial-of-service botnet that's made up of more than 25,000 Internet-connected closed circuit TV devices. The researchers with Security firm Sucuri came across the malicious network while defending a small brick-and-mortar jewelry shop against a distributed denial-of-service attack. The unnamed site was choking on an assault that delivered almost 35,000 HTTP requests per second, making it unreachable to legitimate users. When Sucuri used a network addressing and routing system known as Anycast to neutralize the attack, the assailants increased the number of HTTP requests to 50,000 per second.
  • Study finds Password Misuse in Hospitals a Steaming Hot Mess
    Hospitals are pretty hygienic places – except when it comes to passwords, it seems. That’s the conclusion of a recent study by researchers at Dartmouth College, the University of Pennsylvania and USC, which found that efforts to circumvent password protections are “endemic” in healthcare environments and mostly go unnoticed by hospital IT staff. The report describes what can only be described as wholesale abandonment of security best practices at hospitals and other clinical environments – with the bad behavior being driven by necessity rather than malice.
  • Why are hackers increasingly targeting the healthcare industry?
    Cyber-attacks in the healthcare environment are on the rise, with recent research suggesting that critical healthcare systems could be vulnerable to attack. In general, the healthcare industry is proving lucrative for cybercriminals because medical data can be used in multiple ways, for example fraud or identify theft. This personal data often contains information regarding a patient’s medical history, which could be used in targeted spear-phishing attacks.
