FUTURE: Remove printer driver and raw queue support. · Issue #5271 · apple/cups
Note: The goal of this issue is to have a place to discuss the eventual removal of printer driver support and support for raw queues. This bug has not been scheduled for a specific milestone and this is not something we will implement immediately. Because most printer drivers exist outside of CUPS this change needs to be discussed publicly.
Why do we want to do this? [...]

xubuntu - Why does light-locker keep the screen black after unlock? - Ask Ubuntu
Q: A Xubuntu 16.04 fully patched machine with a freshly created user wont let me unlock after using light-locker to lock my screen (regardless if lock was activated manually or via timeout). The screen remains black (but powered) on correct password entry

Killing light-locker from tty1 will reveal the desktop then (and consequently prevents further locking). [...]

A: TL;DR: light-locker keeps the screen black if systemd cannot read /proc

* light-locker depends on dbus providing IPC.
* dbus depends on systemd-logind providing session information.
* systemd-logind depends on /proc providing process information. [...]

OpenWrt Project: Wi-Fi /etc/config/wireless
The wireless radio UCI configuration is located in /etc/config/wireless.
If the device has ethernet ports, the wireless is turned OFF by default. You can turn it on in /etc/config/wireless by changing option disabled '1' to option disabled '0' (commenting out the line or removing it is sufficient).

The GX620 can support 2 gig modules. With 4 memory slots and a 64 bit CPU and OS it will see 8 Gigs of Ram in bios but you cant use 8. You can only use 3GB or 3.5GB. You CANNOT utilize more memory than 3.5 Gigs even when you install a 64-bit version of your OS This is a GX620 Limitation. Models with Pentium D also support NX and the other requirements for Windows 8.

How to Easily Softmod ANY Fat PS2! | FreeMCBoot & FreeHDBoot Install Tutorial - YouTube
This tutorial has been requested for quite a long time but I waited so long because I was not too keen on the many install methods shown out there. A few recommendations to softmod a PS2 with FreeMCBoot normally include: finding a pre-modded console, using a disc swap trip, using Swap Magic, all of which could be a bit costly or time consuming. With this method all we need is one console and a few tools at our disposal! No swap tricks or discs, no pre-loaded memory card, no reliance on any other system!

This involves installing FreeHDBoot to a hard drive, loading it into the PS2 and using that as our entry point to install FreeMCBoot. That's it! No additional games needed and no need to open up our console!

NDISwrapper - Wikipedia
NDISwrapper is a free software driver wrapper that enables the use of Windows XP network device drivers (for devices such as PCI cards, USB modems, and routers) on Linux operating systems. NDISwrapper works by implementing the Windows kernel and NDIS APIs and dynamically linking Windows network drivers to this implementation. As a result, it only works on systems based on the instruction set architectures supported by Windows, namely IA-32 and x86-64.

Thinkpad-acpi - ThinkWiki
This is a Linux ACPI driver for the ThinkPad laptops written by Borislav Deianov, and currently maintained by Henrique de Moraes Holschuh and is included with the Linux kernel. It aims to support various features of these laptops which are accessible through the ACPI framework but not otherwise supported by the generic Linux ACPI drivers. As a kernel module, thinkpad-acpi works as a bridge to deliver information about certain hardware events like key presses or control the state of certain hardware features by software.

linux-thinkpad/tp_smapi (Lenovo ThinkPad Laptops kernel module)
ThinkPad laptops include a proprietary interface called SMAPI BIOS (System Management Application Program Interface) which provides some hardware control functionality that is not accessible by other means.

This driver exposes some features of the SMAPI BIOS through a sysfs interface. It is suitable for newer models, on which SMAPI is invoked through IO port writes. Older models use a different SMAPI interface; for those, try the "thinkpad" module from the "tpctl" package.

WARNING: This driver uses undocumented features and direct hardware access. It thus cannot be guaranteed to work, and may cause arbitrary damage (especially on models it wasn't tested on).

mkottman/acpi_call: A linux kernel module that enables calls to ACPI methods through /proc/acpi/call. Now with support for Integer, String and Buffer parameters.
A kernel simple module that enables you to call ACPI methods by writing the method name followed by arguments to /proc/acpi/call.

This module is to be considered a proof-of-concept and has been superseeded by projects like bbswitch. It allows you to tamper with your system and should be used with caution.

hamishcoleman/thinkpad-ec: Infrastructure for examining and patching Thinkpad embedded controller firmware
The main purpose of this software is to patch the EC on xx30 series thinkpads to make the classic 7-row keyboards work. There are also patches included (but disabled by default) to disable the authentic battery validation check.

With the patches included here, you can install the classic keyboard hardware on many xx30 series laptops and make almost every key work properly. The only keys that are not working are Fn+F3 (Battery) and Fn+F12 (Hibernate)

Unfortunately, there are a small number of thinkpads with a model number from the "xx30" series that are using a completely different EC CPU and a different BIOS update strategy. Thus they are not currently able to be patched. This is known to be the case for at least the L430, L530 and E330.

It is mainly for my own consumption but I figured it would be nice to packge up for others so they don't have to do all the research and development I had to do. It will probably work on most newer thinkpads of the same vintage (particulalry ones with ivy bridge chipsets) but I can't 100% guarantee anything.

RPI falls back to 1280x720 from x1024. - Raspberry Pi Forums
Q: I have an HDMI->VGA converter module connected to my 'pi, as I have a bunch of TFT VGA monitors lying around, but no HDMI ones.

When I boot the 'pi with the cable attached, it comes up nicely in 1280x1024 as I told it to:

hdmi_drive=1
hdmi_group=2
hdmi_mode=35
hdmi_force_hotplug=1
config_hdmi_boost=4
disable_overscan=1

(hdmi_mode=35 is 1280x1024@60Hz in group 2)
However, somehow, the mode drops to a 60Hz 1280x720 mode when the monitor is not connected during boot. I was hoping to prevent these problems by specifying hdmi_force_hotplug=1, and directly specifying a mode that I want.
Why does it drop to a lower resolution if the monitor is not connected?
Just to be sure: the /proc/cmdline file shows "fbheight=720", so it is not my VGA converter that isn't booted correctly and somehow converting the 1280x1024 mode into 1280x720 (as if such a cheap piece of electronics would be capable of such a feat).

Subpixel layout - Lagom LCD test
Each pixel on an LCD screen consists of three subpixels: red, green, and blue (RGB), that are sitting next to each other. Most operating systems since about 2003 can improve the quality of on-screen text by using these subpixels. However, this only works if the operating system knows how the subpixels are arranged. For the majority of the monitors, the arrangement is RGB (red on the left, green in the middle, and blue on the right). However, on an occasional monitor, it is the other way around (BGR). And if you orient your monitor in portrait mode, the subpixel layout can be V-RGB (vertical RGB) or V-BGR.

Note: this is using the on-board sensor.

The command to do this is:

$ /opt/vc/bin/vcgencmd measure_temp

[...]

A #2: An alternative is to read /sys/class/thermal/thermal_zone0/temp on a recent Raspdian. Divide it by 1000 for degrees C.

$ cat /sys/class/thermal/thermal_zone0/temp

wiringPi updated to 2.52 for the Raspberry Pi 4B | Wiring Pi
Just a quick post to let you know that you’ll need a new wiringPi for the Raspberry Pi 4B.

To upgrade:

cd /tmp
wget https://project-downloads.drogon.net/wiringpi-latest.deb
sudo dpkg -i wiringpi-latest.deb

Check with:

gpio -v

and make sure it’s version 2.52. I’ll push the updated sources shortly.

It will hopefully be part of the official release soon, but for now this will do.

HDMI Configuration - Raspberry Pi Documentation
In the vast majority of cases, simply plugging your HDMI-equipped monitor into the Raspberry Pi using a standard HDMI cable will automatically lead to the Pi using the best resolution the monitor supports. The Raspberry Pi Zero uses a mini HDMI port, so you will need a mini-HDMI-to-full-size-HDMI lead or adapter. On the Raspberry Pi 4 there are two micro HDMI ports, so you will need either one or two micro-HDMI-to-full-size-HDMI leads or adapters, depending on how many displays you wish to attach. You should connect any HDMI leads before turning on the Raspberry Pi.

Preparing Raspberry PI for JTAG Debugging – Sysprogs Tutorials
This tutorial shows how to prepare your Raspberry PI board for debugging with JTAG (we have tested this with Raspberry Pi 1, 2 and 3). Using JTAG will allow debugging the Linux kernel using hardware like Segger J-Link. As Raspberry PI board does not have a connector with a normal JTAG layout, preparing the board for JTAG debugging involves finding the correct pins and wiring them in the correct order. Follow the steps below for a complete walkthrough:

(Solved) Flaky wifi with WRT1900ACS v2 and Android phones - Installing and Using OpenWrt - OpenWrt Forum
Q: I have a wrt1900acs v2 running the latest wifi drivers packaged by @eduperez and it is giving me nothing but problems.

Specifically my Android phones simply refuse to stay connected. Recently it's gotten to the point where it hardly will even connect at all and I've turned it off so that my older tp-link devices are the only APs. We've had hot weather, and I wonder if that's relevant because it was never this bad before.

Rebooting the WRT device seems to fix the problem for a few hours. [...]
