Pierre de LESPINAY's questions

Using 16.04 with Unity I have a touchpad and I'd really like not to have to hold a button while I select text or drag & drop something nor the fake double click before dragging, I never found that handy.
I was able to configure this "three finger drag" feature on a Macbook quite easily and really enjoyed it.

I tried to configure it with touchegg but it does not work with Ubuntu 16 and with libinput-gestures but it does not manage the drag & drop.

All I need is to simulate a click while I have 3 fingers down until I release them.

Does someone know how I can achieve that ?

I'm trying to use the gnome-terminal profiles to cd to a given directory and register some aliases just after the terminal opens.

I have created a script:

~/Document/project1/ops-setup.sh

#!/bin/bash
alias up='docker-compose up -d'
alias down='docker-compose stop'
...

Then a new gnome-terminal Project 1 profile running the following as "custom command"

bash -c "cd ~/Document/project1;. ./ops-setup.sh"

I can see my script launched when I open the terminal with this profile, the terminal remains opened but it does not leave the prompt.

The child process exited normally with status 0.

I tried to add a bash run after it so the prompt remains

bash -c "cd ~/Document/project1;. ./ops-setup.sh";bash

but no alias registered (I guess that's because it is a new process)

I also tried --init-file

bash --init-file <(echo "cd ~/Document/project1;. ./ops-setup.sh")

but bash complains

bash: cd ~/Document/project1;. ./ops-setup.sh): No such file or directory

How can I keep my aliases registered for this Project 1 profile ?

There are multiple ways to keep the terminal opened after running scripts and I that's not my issue. I'm really talking about keeping aliases registered

My (Symfony) application currently crashes, throwing the error:

("The Symfony\Component\Intl\Collator\Collator::__construct() method's argument $locale value 'fr' behavior is not implemented. Only the locale "en" is supported. Please install the "intl" extension for full localization capabilities.")

I actually didn't have intl installed, so I did

sudo apt-get install php5-intl

That also got libicu52 dependency in the process
My application still complains with the same error
I restarted my web server (NginX with php-fpm) manually (even if apt-get does it already).

How can I find the origin of the issue ?

I just bought a motherboard with integrated graphic (intel) 3 outputs:

• 1 x VGA
• 1 x HDMI
• 1 x DVI

I've been able to use both VGA & HDMI but the DVI is not detected.

$ lspci

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)

$ xrandr
VGA1 connected primary 1280x1024+335+1080 (normal [...] y axis) 338mm x 270mm
   1280x1024      60.0*+   75.0
   [...]

HDMI2 connected 1920x1080+0+0 (normal [...] y axis) 160mm x 90mm

   [...]

DP2 disconnected (normal left inverted right x axis y axis)

How can I make my DVI output to actually ouput something ?

I'm trying to use the optical audio output of my motherboard to send the sound to my AV Receiver.

I only see the front channels received by my AV.

Indeed rear channels don't seem to be activated.

How can I activate the rear channels ?

I wanted to use /etc/hosts to define "aliases" for multiple services localhosted like:

127.0.0.1      localhost
127.0.0.1:8080 machin
127.0.0.1:8081 truc

But it doesn't seem to work, surely because /etc/hosts has nothing to do with ports

Is there a way to alias these ports ?

Sometimes I need to open the same directory twice.

If I try to open it from a bookmark, Nautilus sees it is already opened so it simply focuses it.

If I do Ctrl + N, the new window opens home.

Is there a simple way to duplicate the current Nautilus window (just keeping the same directory) ?

Nvidia HDMI audio is a widely asked topic, but I've not been able to find the answer for my case.

Why do we have a different php.ini for the php client ?

Is it a good idea to link the main instead ?

$ sudo ln -s /etc/php5/apache2/php.ini /etc/php5/cli/php.ini

I'm following the official instructions for burning an Ubuntu image on a USB stick from a macbook pro.

Step 8 when trying

$ sudo dd if=/path/to/downloaded.img of=/dev/rdisk1 bs=1m

I'm getting (after having typed my root password)

dd: /dev/rdisk1: Permission denied

Why is this happening?

As I'm using url rewriting to access my Symfony2 application, it is directly available from

http://my_application.my_domain.net

Now I'd like to be able to access the dev environment simply using a different port like:

http://my_application.my_domain.net:8081

I'm using Twinview with Oneiric 64bit with a nVidia card.
I have my primary monitor (with DVI) positioned to absolute 0 and my secondary to the right (with HDMI).

My applications open on the primary monitor but all dialog boxes like the following opens on the secondary

• shutdown
• reload confirmation on firefox
• Save changes to document on gedit
• admin passwords

So when my secondary screen is not on, I am forced to each time Alt + F7 in order to move the new box on the primary display

That's also doing it with some application windows but I got it corrected with CCSM Window Placement

This question seems to be already asked but my problem concerns dialog boxes.

I use Django 1.3 with Python 2.7 on Ubuntu 10.04.

$ python
Python 2.7.1 ...
>>>

I'm trying to install the python module django-grappelli.

$ pip install django-grappelli

Requirement already satisfied: django-grappelli in /usr/local/lib/python2.6/dist-packages

Apparently it's installing into the Python repo's version (2.6) instead of 2.7.
How can I install it on 2.7 ?

I have followed this pretty little tutorial to install red5 on Ubuntu 11.04
I can now run it from /usr/share/red5/red5.sh
But I'd like to have a init.d script like /etc/init.d/red5 start|stop|restart|...
I found one here but when used, it's saying

.: 11: Can't open /etc/rc.d/init.d/functions

What can I do to make it work ?

Edit

Replacing . /etc/rc.d/init.d/functions by . /lib/lsb/init-functions will give me

$ sudo /etc/init.d/red5 stop
/etc/init.d/red5: 50: status}”: not found
stop : missing task name
Try 'stop --help' for more information.
restart : missing task name
Try 'restart --help' for more information.
