Debian Testing issues and fixes

2023-02-05, U: 2024-01-28

If you're using debian testing, I highly recommend turning off automatic upgrades:

sudo systemctl disable unattended-upgrades.service

Various issues I had and fixes I did

Unity/Vulkan crashing (2024-01)

If you get No DRI3 support detected - required for presentation when running vulkan apps (e.g. vkcube), see "Screen tearing and Vulkan" section.

Firefox WebRTC weird popup when joining video call (2023-03)

Go to about:config, search for privacy.webrtc.legacyGlobalIndicator and click on toggle symbol to change it to false.

Bug on Mozilla

Libreoffice undefined symbol error (2022-11)

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/ libreoffice

See AskUbuntu

Firefox not starting (2022-11)

If you downloaded from Firefox page instead of apt.

sudo apt install libdbus-glib-1-2

setxkbmap doesn't work

See Debian wiki

im-config -n none

Screen tearing and Vulkan (intel)

sudo nano /usr/share/X11/xorg.conf.d/20-intel.conf

Put this into the file:

Section "Device"
   Identifier  "Intel Graphics"
   Driver   "intel"
   Option   "AccelMethod"  "sna"
   Option   "TearFree" "true"
   Option      "DRI"    "3"
