Arch Linux User Repository

Hello, Wayland - KDE 6 - Nvidia proprietary 550.54.14 - custom linux-hardened based kernel here.

I had a "grey window issue" no matter what environment variable setting I tried. cf. java

I tried v5.30 and am currently using 5.40.20-beta-api.

I solved the grey window issue by disabling OpenGL as said this avnirvana forum post :

/usr/share/java/roomeqwizard/roomeqwizard.vmoptions

+#-Dsun.java2d.opengl=True

Honestly I don't get why this works, but at least I can use REW, so I thought it was worth sharing here. I don't know if this is to be officialised in the PKGBUILD or not, or if it affects other people than me (I think I found a few posts on manjaro forums as well)

However, I don't see the waterfall render with this configuration.

Anyway, Peace !

Just change the pkgver to 5.30 and rename the icon to install to roomeqwizard.png and it will build well.

I was building roomeqwizard and got a lot of lock-file permssion denied errors:

java.lang.SecurityException: Could not lock User prefs. Lock file access denied.

I managed to fix those by setting the user and system prefs path like so (changed installer invocation line, added -J-D parameters):

sh REW_linux_no_jre_$_pkgver.sh -q -dir "$pkgdir/usr/share/java/$pkgname" -J-Djava.util.prefs.userRoot=$srcdir/java.uprefs -J-Djava.util.prefs.systemRoot=$srcdir/java.sprefs

...I already have jack2 not pipewire-jack

@blackhole try installing jack2 instead of pipewire-jack. I get a grey window and then segfault with pipewire-jack but it does start with jack2.

Here I have only a grey window...

Just installed 03512c4ad708 (first time Roomeqwizard user) and when I then start the program I get

The GUI starts but it seems a little odd and I'm not sure if it's because it's a java app or because of the errors in the terminal when starting the app or because I'm using a tiling window manager (sway).

For example I cannot exit the Preferences popup once I open it...

Just updated but I have an empty window.

Archlinux fully updated with KDE Wayland

@AndyRTR. Added dependencies and override by Your instructions. Build worked both with pkgbuild on my system and with clean environment (archbuilder)

I managed to build it using system jre and fixed the build using a clean chroot:

Please readd back: depends=('java-runtime=8' 'xdg-utils') makedepends=('java-environment=8' 'fontconfig' 'freetype2')

and build it using this export before calling the installer:

export INSTALL4J_JAVA_HOME_OVERRIDE=/usr/lib/jvm/default

This way the bundled jre won't get installed.

btw: search https://www.roomeqwizard.com/changehistory.html for "installer" - it says "Added a Linux installer option to enable OpenGL if waterfall generation produces an error" - So far I couldn't find this option in the installer .sh file to avoid our sed fix.
