[tde-users] geogebra crashes in Ubuntu 20.04 and the corresponding trinity version

Hi I run successfully 5.0.620.0-50 on Ubuntu 16.04. However a colleague of mine runs Ubuntu 20.04 and the trinty version that corresponds to deb http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-sb focal deps-r14 main-r14 deb-src http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-sb focal deps-r14 main-r14 Now either GeoGebra 5.0.634.0 (using a deb provided by geogebra) or what is called a stand alone geobgebra crashes with the following error messages: 17:51:46.193 DEBUG: org.geogebra.desktop.j.a.<init>[-1]: isApplet=false runningFromJar=true 17:51:46.193 DEBUG: org.geogebra.desktop.j.a.aD[-1]: Setting up logging 17:51:46.223 DEBUG: org.geogebra.desktop.j.a.aD[-1]: Logging is redirected to /tmp/GeoGebraLog_mtvcvypbvi.txt java: Fatal IO error 9 (Bad file descriptor) on X server :0.
