Notes

libGL error: unable to load driver: i965_dri.so or GLX generic errors. If you can’t launch the emulator from Android Studio with hardware emulation enabled because of these errors it’s probably because the AVD is starting using wrong versions of the libraries. Manually start the emulator and append -use-system-libs as flag, like this: avivace@debian-tp:~/Android/Sdk/tools$ ./emulator -avd AVD_NAME -use-system-libs The emulator starts with default console port 5554 and should be automatically seen as available device by Android Studio....

If you try and enable the screen sharing feature during a call on Hangouts on Chromium on Debian, it happens absolutely nothing, no error is reported. This is because the Chromium package in the debian repositories is built with the enable_hangout_services_extension=false flag (every other feature of Hangouts actually works). You can download the source, edit the rules file and enable that flag. The produced Chromium package will have the screen sharing feature correctly working....

If you keep getting PAM authentication failed when trying to change shell, even when running as root, you probably have some invalid settings. Change the shell manually using vipw /etc/passwd. chsh should be back working now. vipw can be used to safely edit /etc/shadow and etc/group, too.

A.K.A. Commands I keep forgetting no matter how many milions time I type them Magic SysRq key commands The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system’s state. ALT + SysRq key (usually Stamp) + .. f to call oom_kill Remove kernel module manually installed with make/dkms If you get stuff like: hid-nintendo.ko: Running module version sanity check....

Just to name a few, Teamviewer, megasync, and MATLAB requires some dependecies that are still not in stretch/debian repo. Tuning apt preferences and sources you can mix repositories and satisfy some dependecies with packages from backports, testing or even experimental, just expect something to break (you shouldn’t do this on a production system). Some useful resources to start playing around with apt: AptPreferences Apt pinning My actual apt Configuration

No previews or thumbnails If you’re missing previews and thumbnails while browsing for files, either in settings or in Dolphin, install the following packages: apt install ffmpegthumbs mplayerthumbs kffmpegthumbnailer kio-extras External HDD and Plasma Long story short: you should pay attention using external (mechanical) HDDs with Plasma. The bug is 8 years old and it’s just being ignored (or just not considered a bug).Plasma isn’t spinning down external HDDs and turning off them off while still being powered causes damage, so you have to pay attention on what happens when you mount/unmount them....

I recently got a Thinkpad P14s Gen 2 with an Intel i7-1165G7. Here are some first impressions on how well it works with Linux/Debian. TL;DR Don’t buy it. It sucks. The machine it’s absolutely terrible. Just google for “p14s gen 2 intel throttling” to get an idea. Before initiating with the installation, disable SecureBoot and set the standby/sleep feature to “Linux” on the BIOS. I installed Debian Sid starting from the non-free netinstall image of Buster then did a full upgrade after having added Sid in the sources....

This is resource list meant as checklist for contributing to the Debian project uploading a new package and mantaining it. If you just want to package a software as deb and distribute it in your unofficial repository, checkinstall and aptly provide an easy solution. Get involved: IRC #debian, #debian-mentors Find out if the software already exists in Debian Fill an Intent to Package issue (ITP) Package the software Packaging Intro How To Package For Debian Best Packaging Practices - Debian Developers References Checklists Sponsorships checklists Checklist from the gatekeepers of the archive Ask for sponsorship from a DM or a DD DebianMentorsFaq File a Request for Sponsor bug report in the Debian BTS (sponsorship-requests pseudo-package) Upload the package to mentors....

Play DRM content on Chromium You need the widevine plugin, which ships with Chrome and Firefox by default but isn’t available for Chromium. Install the package chromium-widevine. If the problem persist, manually copy the files libwidevinecdm.so and libwidevinecdmadapter.so from a Chrome install (/opt/google/chrome/) to /usr/lib/chromium/. Or wget https://dl.google.com/widevine-cdm/1.4.8.1008-linux-x64.zip unzip 1.4.8.1008-linux-x64.zip sudo mkdir /usr/lib/chromium sudo mv libwidevinecdm.so /usr/lib/chromium sudo chmod 644 /usr/lib/chromium/libwidevinecdm.so

Install a LISP compiler. We’ll use Steel Bank Common Lisp. Extract the downloaded archive and run install.sh. If the binary location is not /opt/sbcl/bin/sbcl note it. Install emacs sudo apt-get install emacs Set up the MELPA repository adding this to your ~/.emacs file (require 'package) ;; You might already have this line (add-to-list ‘package-archives ‘(“melpa” . “https://melpa.org/packages/")) (when (< emacs-major-version 24) ;; For important compatibility libraries like cl-lib (add-to-list ‘package-archives ‘(“gnu” ....
