On Linux , Running Eclipse Crash My Program.

I've downloaded the latest eclipse (.tar.gz) and unpacked it to /usr/bin and created a launcher for it, but it doesn't launch.
I also created a shell script on the desktop called eclipse.sh, content :
cd /usr/bin/eclipse
./eclipse

and did a chmod 755 /Desktop/eclipse.sh in a terminal as root.
I did a chmod 775 on the eclipse executable as well, but it still won't launch

NB I followed the same procedure with Bluegriffon and that runs OK.

I bet I'm missing something obvious, but just can't think what.

Box is AMD Phenom ll x4 / 8GB DDR3 running Mint 17.1 LXDE.

New to Linux. Run with either Ubuntu Linux on USB or installed on Aspire laptop.
Problem: Chromium and Eclipse act like they are starting but no window opens.

For Eclipse, icon comes up, workplace prompt answered, icon reappears and counts down but no window comes up.
pstree shows that both Chromium and Eclipse have threads running.
Booting with same USB to different computer and all works fine.
Have used both 32 bit and 64 bit USB boot on 64 bit Aspire with no success.

Firefox comes up and works fine

Thanks in advance !
