Ubuntu 18 and HELI-X 8

[jvais2000]

Dear,
I've starting to use HELI-X 4 as an demo version and it's work perfectly.
commande: ./run-HELI-S64.sh

Now I would like to buy and install the full version and up date with the last version (HELI-X 8).
But When I do the same approach
commande: ./runHELI-X.sh

The logicie start but after selected my language the logiciel crack

Did I miss some thinks?

In the worth case, If I buy HELI-X my serial number will work with HELI-X 4 ?

Hello,

it is likely that you have to update/improve your graphics driver. Which error messages do you get in the console?

A license is valid for 4.2 and 8.0

Hi,
I have 2 linux boxes at different locations. The first box I used last week and it was running v8 just fine. I moved to my different box today. Unfortunatly Heli-X8 fails after the language selection like the original poster:

Code: Select all

LANG=C ./runHELI-X.sh 
handleError

^C

Both boxes are running Arch linux with a pretty recent patch level. The main difference in regards to DisplayModes could be that the working one is using a GFX970 with dual screens. The not working one is a single display on a GF1060. (version 4.2 seems to be working on the second machine just fine)

Best regards

Can you send me via email the complete output of the console?

You might try different Java versions, sometimes there are problems with OpenJDK.

Hi,

email has been sent.
Just to keep everyone else in the loop the OpenJDK/GFX driver version is identical on both of my PCs.

Hello,

if I understand it right, the machine with the single display makes the problem.

- If version 4.2 is running and version >5 not, then it is likely that the drivers of the graphics adapter do not offer everything what is needed. You should try to update he drivers.
- We also found out that not every Java version behaves equally well on some machines. On some computers, using OpenJDK or the Oracle JRE makes a difference. So you might try to use another Java version. It might also be reasonable to try an older java .

I hope that helps,

Michael

Hi,

after digging around I found https://github.com/LWJGL/lwjgl/issues/128 which requires xrandr to be installed. If it is not installed the posted error message is thrown. https://github.com/LWJGL/lwjgl/blob/46f ... R.java#L72

"xrandr -q" should produce some output and not a command not found error.

On Arch the required package is xorg-xrandr and after installing it the Heli-X startup works as expected on my second PC
The startup script could check and abort if xrandr is not available before running Heli-X.

Code: Select all

command -v xrandr >/dev/null 2>&1 || { echo >&2 "xrandr not found. Please install xrandr for your distro"; }

Best regards
Karsten

Thank you for your efforts and sharing then with us.
