This is how to get Geany into light mode using KDE. My KDE is already in light mode so I am unsure why Geany opens in dark mode. Open the KDE menu and go to geany then right click > edit. Then click Applications tab at the top. In the line 'Environmental variables' add this
GTK_THEME=Breeze
I was able to force LibreOffice Writer into light mode by editing this line to the libreoffice-writer.desktop file found here
/home/USERNAME/.local/share/applications/
You can see your available theme names here
/usr/share/themes/
Orig :
Exec=libreoffice --writer %U
Edit :
Exec=env GTK_THEME=Breeze libreoffice --writer %U
NOTE THIS HAD TO BE CHANGED ON 2 DIFFERENT LINES
For my job I have many windows open across multiple desktops and I often need to get back to a window on a different desktop quickly, or pressing ALT+Tab isnt a good option because I have 5+ windows open.
In KDE system settings search for 'shortcut' then click Add New button > 'Command or Script' and use a command like this
kdotool search --name slack windowactivate
After that click 'add custom shortcut' button and press the keyboard combo you want.
Ran into a weird issue today - suddenly Brave and Vivaldi refuse to open. Same for Brave Beta. Running from the command line I see something like this

I fixed this by chance by going into the KDE settings > Appearance and changing everything back to Breeze. And under 'Application Style' on the bottom right I clicked 'Configure GNOME/GTK Application Style' and changed that to Breeze (it was blank before). Did not have to reboot and all browsers launch ok now. Did have a slight delay with Vivaldi but it seems ok.
On one of my laptops in Gimp the text has this weird teal color on the anti-aliasing part. If I turn off anti-aliasing the text color is normal.
The text itself is white, but because the tint around it is not, it makes the text look not-white. I tried resetting Gimp to default, this didn't help. I uninstalled Gimp and tried to delete all files in /home/.config - then rebooted and installed fresh. This did not seem to help either.
The fix seems to be go to Image > Precision change to 32 bit. Before it was on 8 bit. I have no idea how or why. This was happening on brand new images, not some old / existing image that was set to 8 bit incorrectly.
I noticed in MX Linux KDE I can't see most emojis , was able to fix it by installing this then rebooting
apt install fonts-noto-color-emoji
Can now see emojis that previously showed up as boxes
Recently installed MX Linux and KDE and my wifi keeps disconnecting for half a second then reconnecting. KDE doesnt tell me that but Facebook and Spotify keep saying I'm offline then right away back online. I checked dmesg and saw this :
wlan0: disconnect from AP 4a:bd:ce:15:85:33 for new auth to 4a:bd:ce:1c:85:34
wlan0: authenticate with 4a:bd:ce:1c:85:34
wlan0: disconnect from AP 4a:bd:ce:1c:85:34 for new auth to 4a:bd:ce:15:85:33
wlan0: authenticate with 4a:bd:ce:15:85:33
This happens over and over.
The fix for me was :
In the XFCE bottom bar I notice even when I have free space the window buttons do not expand in size which makes them hard to read. Here is how to make the window buttons in the taskbar bigger in XFCE
Create file
~/.config/gtk-3.0/gtk.css
add this line
.tasklist { -XfceTasklist-max-button-length: 500; }
restart the panel with this command
xfce4-panel -r

All of a sudden my IPv6 wifi isn't connecting. I change the IPv6 to automatic, automatic dhcp, automatic address only, manual config setting default routes, etc - nothing helps. At least 1 hr just messing with the settings. Each time I disconnect wifi / disable re-enable networking and try again. No joy each time.
Finally the solution was old school trouble shooting. Completely delete the wifi connection and re-connect by selecting the wifi network and just typing in the password. After this is works fine.

Playing a YouTube video in LibreWolf didn't work and I get the console error
NS_ERROR_DOM_MEDIA_FATAL_ERR --FFmpegDataDecoder : Couldn't open avcodec
It seems to get this to work you need to reboot after making the changes, I don't know why. Restarting the browser and even deleting the profile didn't help. Do not ignore this step.
Everything I tried didn't work, then I rebooted, and it worked.
I installed these packages, unsure exactly which 'did the trick'
gstreamer-plugins-ugly
mozilla-openh264
gstreamer-1.20-plugin-openh264
ffmpeg-4
vlc
gstreamer-plugins-libav
libvpx7
