To effectively remedy this, you will need a Java 11 version of Jalview. For Jalview 22.214.171.124 Java 11 is not officially supported but we are working towards that, so you can:
- Download a Java 11 linux installer from https://www.jalview.org/getdown/release/install4j/11/jalview-2_11_1_0-linux_x64-java_11.sh
(if you are using linux a platform other than intel 64 bit you will need to obtain a Java 11 JRE, e.g. from https://adoptopenjdk.net/, and then download the non-bundled-jre unix installer from https://www.jalview.org/getdown/release/install4j/11/jalview-2_11_1_0-unix-java_11.sh).
- Install as usual with the command
- Assuming this installed into the directory ~/opt/jalview, edit the file ~/opt/jalview/jalview and add onto the first blank line
so that the top of that file looks like
#!/bin/sh export GDK_SCALE=2 # Uncomment the following line to override the JVM search sequence # INSTALL4J_JAVA_HOME_OVERRIDE= # Uncomment the following line to add additional VM parameters # INSTALL4J_ADD_VM_PARAMS= ...
Jalview should now run at double sized resolution.
