Same warhings with Netbeans

2018-08-28T21:04:27+01:00

Well. I installed a new SSD disk to my computer and there to empty disk a new Ubuntu operating system. Then I installed Netbeans with apt command. And then I started Netbeans. That gave just same error messages than starting Gephi. So... The last error messages are not bug of Gephi!

Kubuntu got an update to JDK 11. And now starting Gephi it returns to command prompt with error messages.

Is gephi correctly picking java 8? Did you try the software rendering? What driver and graphics card does your system report?

I changed to java 8. That didn't solve the problem.

Yeah the warnings should not be a problem. But you should try to use Java 8, Java 9 or later is not supported yet.

My computer uses open jdk. There is a path java-11-openjdk-i386. If this affects something.

I deleted ~/.gephi and started it in console:

CODE:

me@mycomp:~/temp/gephi/gephi-0.9.2/bin$ ./gephiWARNING: An illegal reflective access operation has occurredWARNING: Illegal reflective access by org.netbeans.ProxyURLStreamHandlerFactory (file:/home/me/temp/gephi/gephi-0.9.2/platform/lib/boot.jar) to field java.net.URL.handlerWARNING: Please consider reporting this to the maintainers of org.netbeans.ProxyURLStreamHandlerFactoryWARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operationsWARNING: All illegal access operations will be denied in a future release

Gephi doesn't find old projects anymore.

Hi,
Please try to delete gephi user directory https://github.com/gephi/gephi/wiki/Troubleshooting and restart.
Also make sure drivers are ok, and if still not working try to enable software rendering as explained here:
https://github.com/gephi/gephi/issues/1962 and https://github.com/gephi/gephi/issues/1836
with env variable

CODE:

LIBGL_ALWAYS_SOFTWARE=1

Hi,
Please make sure to have proper graphics card drivers installed. I suggest trying with latest mesa drivers.

gephi does not display the graph anymore

2018-06-12T02:28:02+01:00

I was using gephi 0.9.2 without any problems under Ubuntu 16.04 LTS.

Suddenly, gephi does not render anything anymore at all. It is still functional regarding tabs, buttons, textual elements, can even calculate stuff in the "statistics" panel, but the main window where the graph usually appears simply does not render anything.

I do not know what triggered this behaviour, but I think it might have happened after a sudo apt-get update, sudo apt-get upgrade. Or maybe it was something else entirely.

I completely deleted gephi, downloaded from scratch, the behaviour persists. Therefore I think it has nothing to do with my gephi per se, but maybe with the java backend?

I would be very thankful for help. I am relying on gephi, it is criticial for my project and I do not know how to fix this, now totally stuck.
