Package: openjdk-21-jre Version: 21.0.8+9-1 Severity: normal By default, text is too small with HiDPI screens, and I couldn't find any documentation in Debian on how to change that.
I've eventually found https://wiki.archlinux.org/title/HiDPI which mentions the sun.java2d.uiScale property, e.g. java -Dsun.java2d.uiScale=2 ... But it is not possible to choose a non-integer scale factor. There should be proper documentation in the java(1) man page and/or README.Debian file. -- System Information: Debian Release: 13.0 APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-security'), (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable-debug'), (500, 'proposed-updates-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 6.7.12-amd64 (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (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 openjdk-21-jre depends on: ii libasound2t64 1.2.14-1 ii libc6 2.41-11 ii libcups2t64 2.4.10-3 ii libfontconfig1 2.15.0-2.3 ii libfreetype6 2.13.3+dfsg-1 ii libgcc-s1 14.2.0-19 ii libgif7 5.2.2-1+b1 ii libgl1 1.7.0-1+b2 ii libglib2.0-0t64 2.84.3-1 ii libgtk-3-0t64 3.24.49-3 ii libharfbuzz0b 10.2.0-1+b1 ii libjpeg62-turbo 1:2.1.5-4 ii libpng16-16t64 1.6.48-1 ii libstdc++6 14.2.0-19 ii libx11-6 2:1.8.12-1 ii libxext6 2:1.3.4-1+b3 ii libxi6 2:1.8.2-1 ii libxinerama1 2:1.1.4-3+b4 ii libxrandr2 2:1.5.4-1+b3 ii libxrender1 1:0.9.12-1 ii libxtst6 2:1.2.5-1 ii openjdk-21-jre-headless 21.0.8+9-1 ii zlib1g 1:1.3.dfsg+really1.3.1-1+b1 Versions of packages openjdk-21-jre recommends: ii fonts-dejavu-extra 2.37-8 ii libatk-wrapper-java-jni 0.40.0-3+b3 openjdk-21-jre suggests no packages. -- no debconf information -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
