9 tips for Ubuntu notebook users

Filed under
Ubuntu

Here are some tips for Ubuntu users who use notebook computers, including how to sync files effortlessly between a laptop and desktop, how to switch CPU speeds on the fly from the desktop, how to power-save your hard disk, and more. Only one or two are specific to notebooks so desktop users may find them interesting too.

All are taken from my brand new book Ubuntu Kung Fu, which contains over 300 other fun and useful tips for Ubuntu.

1. Slow Down a Touchpad’s Scrolling

If you have a notebook computer, you might be used to edge scroll on the touchpad when running Windows. This is where the right edge of the notebook’s touchpad is used as a virtual scrollbar—by running a finger up and down, the currently active window scrolls up and down correspondingly.

You might already have realized that you can activate the edge scroll functionality in Ubuntu using the Touchpad tab of System —> Preferences —> Mouse. The problem I had was that the scrolling was just too fast. A light touch on the pad caused the web page or file listing to fly up or down the screen. The solution was to add a line to the xorg.conf configuration file, as follows:

Open the Xorg configuration file into Gedit:

Leftovers: OSS

Security Leftovers

  • Security updates for Thursday
  • OpenSSL patches two high-severity flaws
    OpenSSL has released versions 1.0.2h and 1.0.1t of its open source cryptographic library, fixing multiple security vulnerabilities that can lead to traffic being decrypted, denial-of-service attacks, and arbitrary code execution. One of the high-severity vulnerabilities is actually a hybrid of two low-risk bugs and can cause OpenSSL to crash.
  • Linux Foundation Advances Security Efforts via Badging Program
    The Linux Foundation Core Infrastructure Initiative's badging program matures, as the first projects to achieve security badges are announced.
  • Linux Foundation tackles open source security with new badge program
  • WordPress Plugin ‘Ninja Forms’ Security Vulnerability
    FOSS Force has just learned from Wordfence, a security company that focuses on the open source WordPress content management platform, that a popular plugin used by over 500,000 sites, Ninja Forms, contains serious security vulnerabilities.
  • Preparing Your Network for the IoT Revolution
    While there is no denying that IP-based connectivity continues to become more and more pervasive, this is not a fundamentally new thing. What is new is the target audience is changing and connectivity is becoming much more personal. It’s no longer limited to high end technology consumers (watches and drones) but rather, it is showing up in nearly everything from children’s toys to kitchen appliances (yes again) and media devices. The purchasers of these new technology-enabled products are far from security experts, or even security aware. Their primary purchasing requirements are ease of use.
  • regarding embargoes
    Yesterday I jumped the gun committing some patches to LibreSSL. We receive advance copies of the advisory and patches so that when the new OpenSSL ships, we’re ready to ship as well. Between the time we receive advance notice and the public release, we’re supposed to keep this information confidential. This is the embargo. During the embargo time we get patches lined up and a source tree for each cvs branch in a precommit state. Then we wait with our fingers on the trigger. What happened yesterday was I woke up to a couple OpenBSD developers talking about the EBCDIC CVE. Oh, it’s public already? Check the OpenSSL git repo and sure enough, there are a bunch of commits for embargoed issues. Pull the trigger! Pull the trigger! Launch the missiles! Alas, we didn’t look closely enough at the exact issues fixed and had missed the fact that only low severity issues had been made public. The high severity issues were still secret. We were too hasty.
  • Medical Equipment Crashes During Heart Procedure Because of Antivirus Scan [Ed: Windows]
    A critical medical equipment crashed during a heart procedure due to a timely scan triggered by the antivirus software installed on the PC to which the said device was sending data for logging and monitoring.
  • Hotel sector faces cybercrime surge as data breaches start to bite
    Since 2014, things have become a lot more serious with a cross section of mostly US hotels suffering major breaches during Point-of-Sale (POS) terminals. Panda Security lists a string of attacks on big brands including on Trump Hotels, Hilton Worldwide, Hyatt, Starwood, Rosen Hotels & Resorts as well two separate attacks on hotel management outfit White Lodging and another on non-US hotel Mandarin Oriental.
