Package: thunderbird Version: 1:115.11.0-1~deb12u1 Severity: normal When starting thunderbird, it displays this error messages:
[GFX1-]: FireTestProcess failed: Failed to spawn child process “/usr/lib/thunderbird/glxtest” (Permission denied) [GFX1-]: No GPUs detected via PCI This is because thunderbird apparmor profile does not let it to execute /usr/lib/thunderbird/glxtest. Adding that one to /etc/apparmor.d/usr.bin.thunderbird fixes the issue. I've no idea why thunderbird wants to run glxtest, but this is a different question entirely. /mjt -- System Information: Debian Release: 12.5 APT prefers stable-updates APT policy: (990, 'stable-updates'), (990, 'stable-security'), (990, 'stable'), (500, 'proposed-updates'), (500, 'oldstable-security'), (500, 'oldoldstable'), (500, 'oldstable'), (99, 'testing'), (50, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386, arm64 Kernel: Linux 6.1.0-21-amd64 (SMP w/24 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=ru_RU.utf8, LC_CTYPE=ru_RU.utf8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages thunderbird depends on: ii debianutils 5.7-0.5~deb12u1 ii fontconfig 2.14.1-4 ii libasound2 1.2.8-1+b1 ii libatk1.0-0 2.46.0-5 ii libc6 2.36-9+deb12u7 ii libcairo-gobject2 1.16.0-7 ii libcairo2 1.16.0-7 ii libdbus-1-3 1.14.10-1~deb12u1 ii libdbus-glib-1-2 0.112-3 ii libevent-2.1-7 2.1.12-stable-8 ii libffi8 3.4.4-1 ii libfontconfig1 2.14.1-4 ii libfreetype6 2.12.1+dfsg-5 ii libgcc-s1 12.2.0-14 ii libgdk-pixbuf-2.0-0 2.42.10+dfsg-1+b1 ii libglib2.0-0 2.74.6-2+deb12u2 ii libgtk-3-0 3.24.38-2~deb12u1 ii libnspr4 2:4.35-1 ii libnss3 2:3.87.1-1 ii libotr5 4.1.1-5 ii libpango-1.0-0 1.50.12+ds-1 ii libstdc++6 12.2.0-14 ii libvpx7 1.12.0-1+deb12u2 ii libx11-6 2:1.8.4-2+deb12u2 ii libx11-xcb1 2:1.8.4-2+deb12u2 ii libxcb-shm0 1.15-1 ii libxcb1 1.15-1 ii libxext6 2:1.3.4-1+b1 ii libxrandr2 2:1.5.2-2+b1 ii psmisc 23.6-1 ii x11-utils 7.7+5 ii zenity 3.44.0-1 ii zlib1g 1:1.2.13.dfsg-1 Versions of packages thunderbird recommends: ii hunspell-en-us [hunspell-dictionary] 1:2020.12.07-2 ii hunspell-ru [hunspell-dictionary] 1:7.5.0-1 Versions of packages thunderbird suggests: ii apparmor 3.0.8-3 ii fonts-lyx 2.3.7-1 ii libgssapi-krb5-2 1.20.1-2+deb12u1 -- Configuration Files: /etc/apparmor.d/usr.bin.thunderbird changed [not included] -- no debconf information
