It wasn't documented *why* swiftshader was disabled. Maybe related to non-DFSG third party libs (see https://bugs.debian.org/909156)? In order to reenable it, I need to poke around and see if I can figure out why it was disabled in the first place.

Package: chromium Version: 121.0.6167.160-1~deb12u1 Severity: normal X-Debbugs-Cc: char...@derkarl.org Dear Maintainer, I'd like to use Chromium's webgl support in headless mode. However, If I don't have an X-server running, and I try to access a website that uses webgl, the browser simply doesn't support webgl, which forces me to use a non-Debian Chromium. I can reproduce this problem with: $ unset DISPLAY $ chromium --headless=new --enable-webgl --screenshot https://get.webgl.org Then Chromium outputs messages like: [843245:843245:0222/035252.118199:ERROR:gl_display.cc(520)] EGL Driver message (Critical) eglInitialize: Could not open the default X display. In theory, I should be able to run Chromium, per their documentation: $ chromium --headless=new --use-gl=swiftshader --enable-webgl --screenshot https://get.webgl.org But it indicates that that is not supported. In order to support swiftshader, a clone of <https://github.com/google/swiftshader.git> must be present in third_party/ and the debian/rules should set the features: enable_swiftshader=true dawn_use_swiftshader=true . It might also make sense to use enable_swiftshader_vulkan=true as well Thank you for your attention and the efforts you put into Debian. cs -- System Information: Debian Release: 12.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.1.0-17-amd64 (SMP w/16 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=C Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages chromium depends on: pn chromium-common <none> ii libasound2 1.2.8-1+b1 ii libatk-bridge2.0-0 2.46.0-5 ii libatk1.0-0 2.46.0-5 ii libatomic1 12.2.0-14 ii libatspi2.0-0 2.46.0-5 ii libbrotli1 1.0.9-2+b6 ii libc6 2.36-9+deb12u3 ii libcairo2 1.16.0-7 ii libcups2 2.4.2-3+deb12u5 ii libdbus-1-3 1.14.10-1~deb12u1 ii libdouble-conversion3 3.2.1-1 ii libdrm2 2.4.114-1+b1 ii libevent-2.1-7 2.1.12-stable-8 ii libexpat1 2.5.0-1 ii libflac12 1.4.2+ds-2 ii libfontconfig1 2.14.1-4 ii libfreetype6 2.12.1+dfsg-5 ii libgbm1 22.3.6-1+deb12u1 ii libgcc-s1 12.2.0-14 ii libglib2.0-0 2.74.6-2 ii libgtk-3-0 3.24.38-2~deb12u1 ii libjpeg62-turbo 1:2.1.5-2 ii libjsoncpp25 1.9.5-4 ii liblcms2-2 2.14-2 ii libminizip1 1.1-8+deb12u1 ii libnspr4 2:4.35-1 ii libnss3 2:3.87.1-1 ii libopenh264-7 1:2.3.1-dmo1 ii libopenjp2-7 2.5.0-2 ii libopus0 1.3.1-3 ii libpango-1.0-0 1.50.12+ds-1 ii libpng16-16 1.6.39-2 ii libpulse0 16.1+dfsg1-2+b1 ii libsnappy1v5 1.1.9-3 ii libstdc++6 12.2.0-14 ii libwebp7 1.2.4-0.2+deb12u1 ii libwebpdemux2 1.2.4-0.2+deb12u1 ii libwebpmux3 1.2.4-0.2+deb12u1 ii libwoff1 1.0.2-2 ii libx11-6 2:1.8.4-2+deb12u2 ii libxcb1 1.15-1 ii libxcomposite1 1:0.4.5-1 ii libxdamage1 1:1.1.6-1 ii libxext6 2:1.3.4-1+b1 ii libxfixes3 1:6.0.0-2 ii libxkbcommon0 1.5.0-1 ii libxml2 2.9.14+dfsg-1.3~deb12u1 ii libxnvctrl0 525.85.05-3~deb12u1 ii libxrandr2 2:1.5.2-2+b1 ii libxslt1.1 1.1.35-1 ii xdg-desktop-portal-gtk [xdg-desktop-portal-backend 1.14.1-1 ] ii xdg-desktop-portal-kde [xdg-desktop-portal-backend 5.27.5-2 ] ii zlib1g 1:1.2.13.dfsg-1 Versions of packages chromium recommends: pn chromium-sandbox <none> Versions of packages chromium suggests: pn chromium-driver <none> pn chromium-l10n <none> pn chromium-shell <none>
