Restore Manjaro grub boot list

If a new Linux is installed in multi-boot after Manjaro, the latter will appear in the new boot list but it will not be bootable.

A solution is to restore and use Manjaro's boot list.


At that other linux grub menu, go into its grub prompt (grub>) by pressing 'c'
At its grub prompt,

grub> search.file /boot/intel-ucode.img root
grub> configfile /boot/grub/grub.cfg
 
Manjaro grub menu will then appear, enter at the first (top) entry and we will boot into Manjaro.


When booted into Manjaro, at terminal,

sudo grub-install /dev/sda
sudo update-grub
 
After restart the Manjaro boot list will be accessible directly.

KDE: add bulk rename in Dolphin

The best bulk rename tool is the one from Thunar, so it's a good idea to just install Thunar

sudo apt install thunar -y

Then run that plugin from Dolphin

kate ~/.local/share/kservices5/bulk-rename-thunar.desktop

paste this:

[Desktop Entry]
Type=Service
ServiceTypes=KonqPopupMenu/Plugin
MimeType=all/all;
Actions=BulkRename;
X-KDE-StartupNotify=false
X-KDE-Priority=TopLevel

[Desktop Action BulkRename]
Name=Bulk Rename
Exec=thunar -B %U
Icon=dialog-information

KDE: Add context menu actions to Dolphin (like extract audio)

To extract m4a audio from mp4:

kate ~.local/share/kservices5/extract-m4a.desktop

Paste:

[Desktop Entry]

Actions=Extract
Icon=dialog-information
MimeType=video/mp4
ServiceTypes=KonqPopupMenu/Plugin
Type=Service
X-KDE-Priority=TopLevel

    
[Desktop Action Extract]
Exec= bash -c 'ffmpeg -i "$0" -map 0:1 -c:a copy "${0%%.*}".m4a' %f
Icon=dialog-information
Name=Extract audio (m4a)
Do the same for flv. For wemb replace m4a with ogg.

Before all, check with mediainfo for the correct audio stream inside the video.

Create pdf from multiple images

Put all png files in a directory, open terminal there and run

convert png.* out.pdf

Replace extension accordingly/

To add all images from that directory into one pdf use

convert *.* out.pdf

Download Google Books

git clone https://github.com/tokland/pysheng
cd pysheng
sudo python setup.py install
It is installed by default in the home directory. But then it can be moved anywhere and launched by executing /pysheng/bin/pysheng-gui. Path to that could be added into a launcher (desktop file) put in ~/.local/share/applications

Each page is downloaded as a separate png file. To create one pdf book out of it, see HERE.

Scan with Canon Printer pixma mg2450

The system app for scanning will not work for this scanner, but the driver installs its own app, runnable with the command:

scangearmp

So, to get a launcher fot it:
 
sudo gedit /usr/share/applications/scan.desktop

and pasting this:
 
[Desktop Entry]
Categories=Graphics;Scanning;
Exec=scangearmp
Icon=scanner
Name=Scan with Canon Pixma mg2450
Type=Application
 
possibly making it executable

sudo chmod +x /usr/share/applications/scan.desktop

Add Internet Download Manager to Firefox & Flashgot



Using Wine (without Playonlinux)

  1. Wine 1.7.4.x at least is needed

sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update



     2. Install or update Wine.

     3. Install IDM (tested 1.7)

     4. To add to Flashgot - open about:config in Firefox address bar and search for "wine". Now Toggle the value of Flashgot.useWine to true.

After restarting Firefox, the downloader will appear integrated to Flashgot.


Using Playonlinux

1. Install a non-listed program.

2. Be sure you use the latest Wine.

3. After installing IDM, follow first part of step 4 from above (about:config in Firefox set  Flashgot.useWine to true).

4. Add to Flashgot with the name IDMan 

5. link to executable /usr/share/playonlinux/playonlinux

6.  add --run IDMan %F /d [URL] under 'Command line arguments template.

Avoid laptop wake-up from suspended state with lid closed


As suggested here, point (2), and in the answers under this question here (here using Gedit as text editor):
sudo gedit /etc/systemd/logind.conf
There should be a line

 # HandleLidSwitch=suspend

Uncomment that, that is,  remove the # before HandleLidSwitch=suspend
and save.

Create pdf from context menu with pdf-generate

Source.



sudo apt-get install imagemagick unoconv ghostscript zenity libfile-mimeinfo-perl
 
 
 
 gedit ~/.config/pdf-generate.conf
 
 
And paste this:


[general]
compression=95 
density=200


So if you want to modify any default parameter, just edit this file before running the tool.

 Main script in charge of the PDF generation k=job should be placed under /usr/local/bin/pdf-generate. See source link to see its content. (Also here.)

 After re-login, a context menu option will appear for selected files as indicated in the source link. For my KDE/Dolphin configuration, this works for selected files if they have the same extension. Otherwise, the best way it just to put all needed files in one folder and then execute the command from the right-click context menu of that folder.
