[Mint] Transmission Remote GUI: download directory path is not absolute

Every few months, I run into this issue when adding a torrent to transgui:

Although there is a 5-year-old closed issue on this bug, which also led to a code adjustment, this bug still seems to exist: https://github.com/transmission-remote-gui/transgui/issues/1270
The user Kethsar has probably already found the right cause and gives some hints on how to solve it. At least it helped me to find a workaround:

  • close transgui if it’s running, otherwise your changes will get overwritten again
  • nano ~/.config/Transmission\ Remote\ GUI/transgui.ini
  • search for the [AddTorrent.transmission]section
  • remove some entries which a related, e.g.
Folder1=/my/path/1
FolHit1=1
FolExt1=
LastDt1=18.02.2024

Folder2=/my/path/2
FolHit2=3
FolExt2=
LastDt2=18.02.2024

...
  • save & quit nano
  • start trangui again and try to add a torrent again

It seems like the issues occurs, when the [AddTorrent.transmission] section reaches Folder50.

[Mint] Sharkoon PureWriter Keyboard not recognized after suspend

In January 2020 I bought a Sharkoon PureWriter Keyboard and since then I had the problem that the keyboard got not recognized after my PC (which runs on Linux Mint) was coming back from suspend mode. Back then I couldn’t find a solution and was just hoping that a newer kernel release will fix this problem in the future. But it did not. So today I was searching again and stumbled again across this post, but now I noticed the new answer from April this year. And it finally solved it!

https://askubuntu.com/questions/1044988/usb-ports-not-working-after-resume-from-sleep-on-ubuntu-18-04

First check with usbreset for the device name and then create the script under the following path:

sudo micro /lib/systemd/system-sleep/reset-keyboard 
#!/bin/sh

case $1 in
  post)
    usbreset "USB-HID Keyboard"
    ;;
esac

And as a last step we make it executable:

sudo chmod +x /lib/systemd/system-sleep/reset-keyboard

[Mint] Install PyWal on Linux Mint 20.1 Cinnamon

“Pywal is a tool that generates a color palette from the dominant colors in an image. It then applies the colors system-wide and on-the-fly in all of your favorite programs.”

https://github.com/dylanaraps/pywal/wiki/Installation

pip3 install pywal

I’m using Variety to change my wallpaper every day automatically. To always get the right colors in my terminal I added some lines in my .zshrc that will always grab the current wallpaper and pass it to PyWal. I’m sure a bash pro would do this in just one line… 🙂

#---PyWal---#
# load previous theme
(cat ~/.cache/wal/sequences &)
# get picture path
picturepath=$(gsettings get org.gnome.desktop.background picture-uri) 
# remove prefix & suffix
prefix="'file://" 
suffix="'"
picturepath=${picturepath#"$prefix"} 
picturepath=${picturepath%"$suffix"}
# set colors
wal -n -q -i "$picturepath"
#---PyWal End---#

There are many plugins/tools you can combine with PyWal:

[Hardware] ASUS TUF GAMING B550M-PLUS and RTL8125B Realtek

Just switched some hardware parts in my main PC:

I moved from Intel to an AMD build. I kept my boot disk with Linux Mint 20 and everything was running out of the box, except there was no ethernet connection available. The RTL8125B Realtek network card is not yet supported on a Kernel < 5.9. Since I’m running Kernel 5.6.14, I had to manual install it.

Go to: https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software

Download the “2.5G Ethernet LINUX driver r8125 for kernel up to 5.6”, untar and follow the installation instructions from the README. In fact you only have to run

sudo ./autorun.sh
#check with
lsmod | grep r8125
ifconfig -a

[SAP] Install SAP Gui for Java 7.50 on Linux Mint 20

Download

First have a look at the Requirements and FAQ.
Find the download link in the SAP Support Portal here. You will need a valid S-User and download permissions.

If you are not able to download the installer via Support Portal, there is a little workaround. Both, the installer for SAP Gui for Windows and SAP Gui for Java are also delivered with the AS ABAP 752 SP04, developer edition:

“The actual download (in the form of several .rar files), along with more information is available from the SAP Community Trials and Downloads page. Search for “7.52 SP04″ for convenience.”

You will have to download all 11 .rar files (about 14,6GB). When unziping, you’ll find a folder called client (about 1,2GB) containing both installers.

Installation

Since SAP Gui 7.50 Rev 5, Oracles JDKs is not necessary to run SAP Gui for Java, instead you are able to use OpenJDK. Read more about it here. And since version 7.50 Rev 8 the installer includes SapMachine and OpenJFX. Read more about it here. In this case, you don’t even have to install OpenJKD and OpenJFX by yourself and don’t have specify the module path, because it comes containerized within the SAP Gui.
So better first check the version of your downloaded gui. I’ve got SAP Gui 750 rev 5 within the AS ABAP 752 SP04. So let’s install openJDK & openJFX.

sudo apt-get install openjdk-11-jre openjfx
java --version

Finally lets install the SAP Gui:

cd JavaGUI/
java -jar PlatinGUI750_5-80002496.JAR install

The important step during the installation of SAP Gui for Java Rev 5 is to define the option for the module path. The module path hast to point to the OpenJFX lib-path:

/usr/share/openjfx/lib

Now you should be able to run the SAP Gui on Linux Mint 20

Eclipse ADT

When using Eclipse with ADT in combination with SAP Gui for Java and receiving the following error:

"The system reqirements are not met.Could not find: javafx.propertiesin: /usr/lib/jvm/java-11-openjdk-amd64/libYour Java Virtual Machine seems not to support JavaFX, required to run the SAPGUI for Java 7.50 rev 5.Please make sure you provide a valid path to the Java FX modules during guiinstallation."

You also have to add the OpenJFX path to the eclipse.ini file. Read more about it here.

--module-path=/usr/share/openjfx/lib
--add-modules=ALL-MODULE-PATH
