To electronically sign documents like PDF install the AUR package autofirma.
This is a displaylink USB screen I use for video editing and also following tutorials while I run a program. Make sure you have linux-headers package already installed. You must install the displaylink AUR package that allows configuring displaylink monitors using Xrandr. Then create the file /usr/share/X11/xorg.conf.d/20-evdidevice.conf with the following content:
Section "OutputClass"
Identifier "DisplayLink"
MatchDriver "evdi"
Driver "modesetting"
Option "AccelMethod" "none"
EndSectionand reboot. There is a flickering in the cursor sometimes. I still haven't debug the origin.
My config for xrandr screen on the right side:
xrandr --output eDP-1 --primary --auto --output DVI-I-1-1 --right-of eDP-1 --auto
If I want it rotated then
xrandr --output eDP-1 --primary --auto --output DVI-I-1-1 --rotate left --left-of eDP-1 --auto
It is preferable to place the rotated screen on the left side due to the view angle specs of the screen. The view angle from above is much greater than from below. So if you place it on the right side, you are viewing the screen from below. Whilst if you place it on the left side you are viewing it from above.
mirror screen:
xrandr --output eDP-1 --primary --auto --output DVI-I-1-1 --same-as eDP-1 --auto
My config for extra screen:
xrandr --output eDP-1 --primary --auto --output HDMI-1 --right-of eDP-1 --auto
or mirror:
xrandr --output eDP-1 --primary --auto --output HDMI-1 --same-as eDP-1 --auto

For a free, open source alternative driver to the proprietary 3DConnexion, install the packages spacenavd and the config tool spnavcfg. Start the mouse with:
sudo systemctl start spacenavd
Enable the service if you want to run it everytime you boot.
sudo systemctl enable spacenavd
At the time of writing (September 2019) Space Navigator is having trouble with the Appimage version of FreeCAD. It works just fine in the AUR compiled version. It just takes a long time to compile.

My old tablet for drawing and painting, still works like a charm. I am learning to use it now with grease pencil, the new feature in blender 2.8. You need to install the xf86-input-wacom and reboot. You should now see some devices with the command xsetwacom list devices.
[unix ~]$ xsetwacom list devices

Wacom Intuos3 6x8 Pen cursor id: 18 type: CURSORIf you use dual head monitors xrandr sets both monitors as one big screen, mapping the tablet to the whole virtual screen and deforming aspect ratio. For a solution, map the Stylus and the eraser (id 10 and 17) to the desired screen, in my case, eDP-1.

This electronic piano can be used as a MIDI input in LMMS and other software. I like it because it has pressure sensitive keys and it's full size. It does not need any driver. Just connect it via usb and check that it is properly detected:
[unix ~]$ lsusb
Bus 001 Device 009: ID 0499:160f Yamaha Corp. P-105Then with alsa-utils installed check the device number for input and output:
[unix ~]$ aconnect -i

client 14: 'Midi Through' [type=kernel]

client 14: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 20: 'Digital Piano' [type=kernel,card=1]
0 'Digital Piano MIDI 1'And you can connect this device to your DAW or MIDI software. Check the activity with aseqdump. So far is not detecting pressure sensitivity. I haven't checked the foot pedal yet.

I bought this electronic drum for my kid in fab12 Shenzhen and today while I was about to pack it for the basement I saw USB MIDI among the chinese characters. So I decided to give it a try and see if if was a USB MIDI device. When I plug it dmesg -w says

Install sane and optional the frontend xsane. Add yourself to the scanner group and reboot sudo usermod -a -G scanner $USER
Check that your scanner is listed scanimage -L. If you don't want your cameras to be listed comment v4l in /etc/sane.d/dll.conf.
Try to scan something through xsane or manually using the device name shown in the step above:
scanimage --device "genesys:libusb:001:004" --format=png > test.png
First make sure that your BIOS has a security setting that allows you to use the Thunderbolt port as a display port. Install the nvidia nvidia-settings nvidia-utils opencl-nvidia cuda cudnn nvtop packages. You can use the card as a coprocessor for training neural networks, blender cycles, etc. But if you want to use Blender EEVEE, X-Plane, etc you need to connect an external monitor to the card and switch GPUs.
How to switch GPUs for internal to eGPU:
- Clone the following repository https://github.com/TheBeachLab/gswitch
- Follow the installation instructions
- To switch to eGPU
sudo gswitch egpu - To switch to internal
sudo gswitch internal
Note: From time to time the PCI ID of the egpu will change and switching to the egpu will stop working. In that case run
sudo gswitch setupagain.
At every kernel update go to ~/opt/nvidia-patch and git pull then check if your version nvidia-smi is compatible with the patch sudo bash patch.sh -l then sudo bash patch.sh and sudo bash patch-fbc.sh
This is an external GPU adapter that I bought on Amazon. My version has a expresscard that I use for my Thinkpad X220. Seems to work with the Radeon HD6450. The following command detects the card:
lspci -k | grep -A 2 -i "VGA"
But does not detect my Nvidia 8800GT so far. Still researching.
Install the open source driver xf86-video-ati. Install also radeon-profile-git AUR package which installs a qt application radeon-profile to display info about a Radeon card.
If I insert the expresscard after booting, radeon-profile shows no card. I suspect the Kernel module is not loaded.
If I reboot with the expresscard inserted then the radeon kernel module loads and the screen goes to the radeon HDMI, leaving the laptop screen black. startx fails: XF86enableIOPorts operation not permitted. KMS Kernel modesetting enabled
I use libinput driver instead of the former xf86-input-synaptic. Something that I hate of the standars behaviour of the trackpad is the area for middle and right click, because I usually accidentally click the wrong button.
There is another problem. By default touchpad is disabled while typing. But for playing with the synths knobs you will want it activated. In order to have the touchpad working while a key is pressed do the following:
[unix ~]$ xinput
