Showing Desktop Icons in GNOME 44

INFO

It is important to note that the following writeup has been found to be entirely copied from a website and is being kept here solely for archival purposes.

1. Install nemo from your distribution's repositories. On Arch, enter this command on the Terminal application:

   sudo pacman -S nemo

2. Open a text editor and copy the following text into a new empty file:

   [Desktop Entry]
   Type=Application
   Name=Nemo
   Comment=Start Nemo desktop at log in
   Exec=nemo-desktop
   OnlyShowIn=GNOME;
   AutostartCondition=GSettings org.nemo.desktop show-desktop-icons
   X-GNOME-AutoRestart=true
   NoDisplay=true

3. Save the text file as ~/.config/autostart/nemo-autostart-with-gnome.desktop

4. Optional step: In case you want Nemo to behave more similarly to nautilus desktop layout, you can enable the setting running this command on the terminal:

   gsettings set org.nemo.desktop use-desktop-grid false

Voila! And that's it! Next time you log in, nemo will automatically display icons over the desktop background. If you don't want to log out, you can also manually start it using the Alt+F2 prompt to run nemo-desktop

mysql connector issues with mariadb

Date : 11 July, 2023

Springboot and probably other systems are failing issues connecting to mariadb on latest releases.

Issues is attributed with recent mariadb-11.X update that caused mysql-connector to break attributed to tx_isolation after MySQL 8.0 update.

To fix that :

1. Install downgrade from AUR (for Arch based systems).

   yay -S downgrade

2. Downgrade mariadb to 10.10.3. You can add these package to IGNORE by choosing them on prompt while downgrading.

   systemctl stop mariadb
   sudo pacman -Rs mariadb
   sudo downgrade "mariadb-libs=10.10.3" "mariadb-clients=10.10.3" "mariadb=10.10.3"
   sudo systemctl enable --now mariadb

3. Check if mariadb is working or not. Use old password for same.

   mariadb -u root -p

4. If that doesn't work, reset the configuration

   DANGER

   Data loss!

   sudo bash
   systemctl stop mariadb
   rm /var/lib/mysql
   mariadb-install-db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
   mariadb -u root -p
   MariaDB [mysql]> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password'; # new_password is your new sql password
   sudo systemctl enable --now mariadb

5. Alternatively, you can reset your mysql password

   i) Stop mariadb.service.

   ii) Start the MariaDB server with safety features:

   sudo bash
   mariadbd-safe --skip-grant-tables --skip-networking &

   iii) Connect to it:

   mariadb -u root

   iv) Change root password:

   MariaDB [mysql]> FLUSH PRIVILEGES;
   MariaDB [mysql]> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
   MariaDB [mysql]> exit

   v) Kill running mariadbd* processes:

   kill $(cat /var/lib/mysql/$HOSTNAME.pid)

   vi) Start mariadb.service.

logseq and git

INFO

For some reasons, logseq + git doesn't work the same as it should with flatpak

For logseq installed using system package, to push a commit using ssh in arch linux

1. Make sure you have the necessary git plugins installed in logseq from plugin marketplace.

2. If you're using ssh for git, you might be getting errors like ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory. For resolving those, a workaround is to install ksshaskpass and symlink /usr/bin/ssh-askpass to ksshaskpass.

   sudo pacman -S ksshaskpass
   sudo ln -s $(which ksshaskpass) /usr/bin/ssh-askpass

DPI issues in PDFs/while taking screenshots when using Firefox RTF (resistfingerprinting)

Text is generally fuzzy on high DPI displays on firefox due to DPI set to 1 due to RTF. This behaviour is also suplemented in firefox screenshot which has been reportedly not working the same as expected(overcropped edges) due to that, requiring you to manually scale the display for complete shoot.

1. Switch from privacy.resistfingerprinting to privacy.fingerprintingProtection.
2. Set privacy.fingerprintingProtection.overrides to +AllTargets,-WindowDevicePixelRatio,-CSSPrefersColorScheme. CSSPrefersColorScheme is optional, and you can ignore that by the way.
