How to enable Hardware acceleration in Firefox ESR

For reference, my computer has intel integrated graphics, and my operating system is Debian 12 Bookworm with VA-API for graphics. While I had hardware video acceleration enabled for many application, I had to spend some time last year trying to figure out out how to enable it for Firefox. While I found this article and followed it, I couldn't figure out at first how to use the environment variable. So here's a guide now for anyone new to Linux!

First, determine whether you are using the Wayland or X11 protocol Windowing system if you haven't already. In a terminal, enter:

echo "$XDG_SESSION_TYPE"

This will tell you which Windowing system you are using. Once you've followed the instructions in the article linked, edit (as root or with root privileges) /usr/share/applications/firefox-esr.desktop with your favorite text-editing software. I like to use nano! So for example, you would enter in a terminal:

sudo nano /usr/share/applications/firefox-esr.desktop

Then, navigate to the line that says "Exec=...". Replace that line with the following line, depending on whether you use Wayland or X11. If you use Wayland:

Exec=env MOZ_ENABLE_WAYLAND=1 firefox

If you use X11:

Exec=env MOZ_X11_EGL=1 firefox

Then save the file! If you are using the nano editor, press Ctrl+x, then press Y and then press enter! Restart Firefox ESR if you were already on it, and it should now work! Enjoy!

Cara Menjalankan Paket .deb di Linux tanpa Instalasi

Halo Pembaca! Saya adalah pengguna ArchLinux. Namun, seringkali aplikasi yang saya butuhkan hanya tersedia untuk distro Ubuntu, Debian, atau distribusi populer lainnya. Biasanya, aplikasi-aplikasi tersebut hanya tersedia di apt atau hanya dapat diunduh dalam format .deb. ArchLinux tidak mendukung program-program Debian tersebut secara bawaan—dan mungkin itulah sebabnya distro ini tidak terlalu…

How to install the native gog(and maybe steam? I dont own it to check) linux version of Star of Providence (monolith: relics of the past)! a very niche tutorial for maybe 6 people in the world.

This also might slightly help as a base guide in learning how to troubleshoot programs and games on linux.

This guide assumes you have Steam installed and can be trusted to find certain library files if you do not already have them installed. On my personal system I am running openSUSE tumbleweed and will be using Lutris to launch the game, but equivalent steps for launching through Steam will be provided when needed.

Firstly, turn off hidden files.

the base game is 32-bit only and requires files from /.steam/bin/steam-runtime/lib/1386-linux-gnu Base game+DLC is 64-bit only and requires files from /.steam/bin/steam-runtime/lib/x86-64-linux-gnu

if you're using Lutris. inside your monolith game directory place a new folder named "lib" place "libcrypto.so.1.0.0" and "libssl.so.1.0.0" from your respective steam-runtime/lib folders into the monolith lib directory in lutris, right click and confiure on monolith, select toggle "advanced" on the top right of the window under game options "add directory to LD_LIBRARY_PATH" add your lib directory in the monolith folder

on Steam.

into your game properties tab paste either

for base game

LD_PRELOAD="~/.steam/bin/steam-runtime/lib/1386-linux-gnu/libssl.so.1.0.0 ~/.steam/bin/steam-runtime/lib/1386-linux-gnu/libcrypto.so.1.0.0" %command%

OR

for base + DLC

LD_PRELOAD="~/.steam/bin/steam-runtime/lib/x86_64-linux-gnu/libssl.so.1.0.0 ~/.steam/bin/steam-runtime/lib/x86_64-linux-gnu/libcrypto.so.1.0.0" %command%

for the base game we should be done and the game is playable however, with the DLC at this point we're still missing (on opensuse tumbleweed, your system might be different, check your games logs while trying to launch)one library file to make the game launch, it wants to look for libcurl-gnutls.so.4 which is unavailable in the repos of non ubuntu/debian based distros, however this file (seems to be) completely cross compatible with libcurl.so.4 so we're going to be making a symbolic link, so when the game searches for libcurl-gnutls.so.4 it will find libcurl.so.4

open a terminal in your system's /lib64/ folder, with Dolphin this can be done by right clicking an empty space and under actions select "open terminal here", alternatively just move to the directory inside of your terminal paste | sudo ln -s libcurl.so.4 libcurl-gnutls.so.4

(now, this might have negative consequences however, I do not know what they would be and someone who actually codes might be able to pitch in here. if so, just add it to the lib directory for the game for lutris or add a new folder under LD_PRELOAD on the steam properties) the game should now be playable

Alternatively to all of this, just use proton. on Steam just change the compatibility mode to the latest version and in Lutris install the base games windows version and run it using proton or wine-ge, to get the dlc to work select "Run EXE inside Wine prefix, this can be found to the right of the play button at the bottom of the list to the right of the wine button. Now launch the DLC installer. Congrats! You got the game to work in hopefully a quarter of the time it took me to both figure this out and document all of this!
