Dual Monitors with NVidia in Ubuntu

Filed under
HowTos

It’s quite a pain to get dual monitors working your first time using Linux, however I hope this guide will make the process relatively quick and painless.

The first step towards dual monitors involves installing the NVidia 3D drivers. Luckily, NVidia has great Linux support and the drivers can easily be downloaded from the Ubuntu repository. Ubuntu Feisty Fawn gives users the option to install these drivers when first installing, but in case you chose not to install these drivers, all it requires is one line of code in the terminal:

sudo apt-get install nvidia-glx

Now that the drivers are installed, let’s make sure that we’re using them. First, let’s check xorg.conf, the main location for display settings in Linux. Type sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup. This ensures that we have a backup copy in case some of the settings we’re about to edit break X and don’t allow you to use a graphical interface! I suggest always doing thins before changing settings in Linux manually to ensure easy recovery later. Now we’re ready to edit our settings, so type sudo gedit /etc/X11/xorg.conf. Under the module section, replace “nv” with “glx”. Under the device heading, make sure that Driver says “nvidia”. Under the screen section, add the following line:

Raspberry Pi CM3+ gets its own keyboard computer

Clockwork is pre-selling an $219 to $249, open-spec “DevTerm” retro AiO PC kit with a Raspberry Pi CM3+, a keyboard with gamepad, a 6.8-inch IPS screen, a thermal printer, and a battery holder. Future options will include RK3399 and Allwinner H6 models. Clockwork’s open source DevTerm Kit runs Linux on a Raspberry Pi Compute Module 3+ Lite (CM3+ Lite) housed inside a keyboard chassis. Unlike the Raspberry Pi 4-like, keyboard form-factor Raspberry Pi 400, the fully hackable, retro-game oriented DevTerm boasts an integrated display and even a thermal printer. Read more

Help in the fight against DMCA anti-circumvention rules by December 7th

The United States Copyright Office is now accepting comments in support of exemptions to the Digital Millennium Copyright Act's (DMCA) anti-circumvention provisions, and we need your help by December 7th to ensure that every new exemption is granted. The DMCA has been making headlines recently for all the wrong reasons. The Recording Industry Association of America (RIAA) recently was able to temporarily have youtube-dl removed from GitHub, via a poorly thought out take down notice. GitHub has now restored youtube-dl, but not before forcing some changes to the project. While the safe harbor provisions of the DMCA can have some use, it's clearly an abuse for the RIAA to interfere with such a project -- particularly given that part of their notice was a claim about some sort of violation of YouTube's rights, not the RIAA's, and was related to a different section of the DMCA, the section 1201 anti-circumvention provisions. Those provisions create legal penalties for avoiding Digital Restrictions Management (DRM), and even harsher penalties for sharing the tools to do so. This last point -- the separate penalties for sharing tools used to remove restrictions -- is especially important. Recently, Google demanded GitHub take down tools used to work around its Widevine DRM. This just underscores that users will be unable to take advantage of even approved exemptions, unless they are able to write their own tools from scratch to get the DRM out of their way. It's like saying everyone is free to cook what they want in their own kitchen, but buying and selling stoves is illegal. Read more Also: Software Freedom in Europe 2020

OSMC's November update is here with Kodi v18.9

Last month, we released Debian Buster with Kodi v18.8. While this version had the majority of fixes backported from Kodi v18.9 which was still in progress, we've decided to issue a final release of the Kodi Leia series in the form of an 18.9 point release. Our focus will now be on enabling OSMC support for Kodi v19 (codename Matrix) which is now in beta release. This new version of Kodi will bring a significant number of improvements. However -- it should be noted that this new Kodi release will also introduce some caveats, and this is why we've chosen to polish the Kodi v18.x series of OSMC as much as possible, particularly as some users may need to stay on this version if there device is no longer supported or their add-ons do not work with the new version. Kodi Matrix upgrades its Python implementation from Python 2.x to Python 3.x. While the majority of add-ons have already been updated to support this new version, you may find that some add-ons do not work. Furthermore, Raspberry Pi 0, 1 and Vero 2 will no longer be supported, meaning that this release will be the final supported version for these devices. Read more
