Hello,

I’m running the install-script with su-privileges, I’m running the install-script with su-privileges, but after drawing the first window (for the language selection), there are no buttons or text.

Have you tried running the installer and/or the application without su-privileges?

I tried using the “unattended installation” as well as unpacking the tarball, both open a window but fail to draw it’s contents. The flash screen also appears only as a grey rectangle.

We have not tested Oxygen or the installer on CentOS 7, but the problem you are experiencing (empty windows) seems to be between Java and the X11 graphical system.
Please check the version of Java being used, "java --version"

I found an article about a similar problem with Intellij (also a Java app) on CentOS:
https://intellij-support.jetbrains.com/hc/en-us/community/posts/360000436304-Intellij-appears-as-a-blank-white-window-when-opened-on-Centos
If you are working remotely (e.g. via XRDP), check if the framebuffer is configured to use 24-bit of color.
Someone mentioned there that he resolved the problem in CentOS 7.6 by editing /etc/xrdp/xrdp.ini and changing max_bpp=24.

If the problem persists, consider installing v21.1, OpenJDK distribution, "Linux 64-bit (Includes OpenJDK 12.0.1)"?

Dear list,

I’m trying to install oxygen 19.1 on a VirtualMachine running centOS 7 with GNOME via X11 and OpenJDK 1.8.0.

The functionality is there – I can open the drop-down menu – but no text or buttons.

The VM sits behind a firewall which blocks ftp-protocols and cannot be altered, because we don’t administer it – this has led to problems in the past, therefore it’s worth mentioning.

I tried Google, but came up empty handed. I’m hoping someone here ran into similar problems and has found a solution.

Best wishes,

M. Wingerath
