ubuntu about studio HOT 3 OPEN

what error do you see?
using today's release (3.35 2019.04.09) of studio for kdb+, it works ok for me for these versions:
$ java -version
openjdk version "1.8.0_03-Ubuntu"
OpenJDK Runtime Environment (build 1.8.0_03-Ubuntu-8u77-b03-3ubuntu3-b03)
OpenJDK 64-Bit Server VM (build 25.03-b03, mixed mode)
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.4 LTS
Release: 16.04
Codename: xenial

maybe you don't have a windows x11 server running? Please provide more info...

from studio.

Good point, no- I dont have x11 running. bizarre though- other java apps seem to open fine.

Java details

$ java -version
openjdk version "9-internal"

OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)

Here is the portion from the logs:

from studio.

ok, a brief googling suggests there are general issues with openjdk 9. So all I can suggest is to try a more recent release of openjdk or Oracle JDK/JRE 8.

from studio.
