Linux Hardware

NVIDIA DRIVERS

In K-menu: goto system/Hardware drivers manager and activate the NVIDIA driver.

Was a problem in Kubuntu 10.04, with every kernel update, the Nvidia drivers had to be reinstalled manually.

OK again in 10.10, .bad in 11.10, OK again in 12.04.

RADEON DRIVERSUse the standard open source drivers, the work best

BEID (Belgian Electronic ID card support)

MOUNT network drives

Howto mount network disks from my Synology NAS

SAMBA mount with the cifs protocol (cifs is the successor of smbfs)

when trying to mount a drive with the command

sudo mount -t cifs -o username=xxxx,password=xxxx //192.168.0.101/home /mnt/share

I always got an error about a missing helper program, so after googling around, I found that I needed to install the package cifs-utils

A way that does not show the password in the command is

sudo mount -t cifs -o credentials=/etc/cifsmarc //192.168.0.101/homes /nas

with contents of the file /etc/cifsmarc

username=xxxxxxxx

password=xxxxxxx

When you want to mount the disk at startup, it must be put in /etc/fstab like this

//192.168.0.101/homes /nas cifs credentials=/etc/cifsmarc,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0

Brother MFC-9970CDW All-in-One

For DEB and RPM distros, Brother made an installation script that downloads and installs the drivers.

Install printer & cups drivers for Manjaro and Arch linux

- In Pamac, enable the AUR repositories

- Install the brother-mfc-9970cdw driver

- Configure the driver via the KDE settings/hardware/printers application, or via CUPS http://localhost:631/
LPR is for wired connections, use Connection: ipp://192.168.0.200 for network connection

Install scanner driver for Manjaro and Arch linux

- pamac install brscan4

- brsaneconfig4 -a name=brother9970 model=MFC-9970CDW ip=192.168.0.200

- sudo saned restart (restart the sane deamon to activate the new settings)

To see what scanning devices are available:

scanimage -L device `brother4:net1;dev0' is a Brother brother9970 MFC-9970CDW device `v4l:/dev/video0' is a Noname USB2.0 HD UVC WebCam: USB2.0 HD virtual device

To change the scanner IP adres, do the following

- sudo kate /opt/brother/scanner/brscan4/brsanenetdevice4.cfg and change the IP adress

- sudo saned restart (restart the sane deamon to activate the new settings) sudo service saned restart in newer Ubuntu versions

The scanner works fine in single and double sided scan mode using gscan2pdf !!

The scan-key tool also works and opens automatically GIMP when scanning to a picture.

- Roland G70
  - With synaptic, install qjackctl (jack soundsystem) and Rosegarden (midi play & recording application)
  - connect the USB cable.
  - In the G70, enable access to the internal memory via USB.
  - This makes it possible to transfer midi files and arranger styles between PC and G70.
  - It is also possible to copy a new firmware into the G70.
  - In the G70, change the midi interface from classical midi to USB.
  - Start jack control from the sound & video application menu and connect the G70 midi in and midi out
  - interfaces to the input and output ports.
  - The G70 midi ports appear in the interfaces list, once you did the previous step on the G70.
  - Start Rosegarden (or another) midi application and set the play & record devices to the G70 midi ports.
  - - Voila, you can start controlling the G70 via your PC

When starting Rosegarden, I got following warning message: System timer resolution is too low

Rosegarden was unable to find a high-resolution timing source for MIDI performance.

This may mean you are using a Linux system with the kernel timer resolution set too low.

I ignored it, and the application just works.

Perhaps, when you have a complex midi file with lots of fast notes, this could pose problems.

To avoid this, you can install a low latency kernel.
