Program not showing

#1

I installed everything on Ubuntu 14.04 , but when I start the program, I can see it is running in the background (ps aux), but I don't see the interface.
It is like it is in headless-mode or something. Any idea what to do about this?

update:

Perhaps this has t do with it:
when I run /opt/axoloti/Axoloti directly I get some java messages, including:
INFO: Link to firmware CRC 6FDF7F14

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: /tmp/usb4java4290878553669200526.tmp/libusb4java.so: /tmp/usb4java4290878553669200526.tmp/libusb4java.so: failed to map segment from shared object: Operation not permitted

i dont know anything about Java, so how I do I solve this?

Ubuntu 14.04 x86 or x84 or a different architecture? Could you post the output of "uname -a"?
I haven't heard anyone reporting this before.

hey Johannes.
I think I found it.
/tmp was mounted 'in memory' (which is fine if you have enough memory and is better for your HD/SSD ) , but I think that created some permissions issue.
turning it off and it starts the interface. ( remove from /etc/fstab , then mount -a ) .

Then adding the right permission/mode flags in your /etc/fstab should also sort it.
My guess : do you have -noexec in the /tmp line in your fstab? If so, remove the -noexec flag, then you can keep using tmpfs.

#5

yes, I have -noexec flag there.
I'll try if it works if that is turned off, even though there was probably a reason why I did that (long time ago). it adds some extra level of security.
thanks.

For java it is normal behavior that it unpacks native libraries to /tmp. Other java programs that use native libraries will fail too.
