Quartus II 12.0 Software Linux no tutorials can be opened

Hi,

maybe Quartus doesn't have the right to access to /usr/bin.

Launch Quartus as super user and tell us if you still have this problem.

Regards

I already launched Quartus with a "sudo" (gksudo) !!!

If I start it without root-rights no changes in preferences, path, etc. will be saved for the next Quartus session!

That's what I forgot to mention... sorry!

problem with internet connectivity/tutorials still exists!

kind regards

I installed firefox by using the Xubuntu repository.

I try to avoid installations by myself

I even tried chromium and it didn't work, too!

I just realized that I even cannot start the pdf tutorials from

the help menu.

So this can't be browser related? Or am I wrong?

Apparently, it does not work well with Chrome.

The PDF Tutorials from the help menu are opened in the web browser specified in Quartus (Tools/Licence Setup/Internet Connectivity).

What happens if you lauch /usr/bin/firefox? (maybe the symbolic link does not point to the right place, or does not exist)

Verify once again that /usr/bin/firefox is the web browser of Quartus.

if I try to launch /usr/bin/firefox from shell firefox starts immediately!

So the symbolic link should be set correctly?!

ok I just tried to use some alternative browsers!

Using "konqueror" or "epiphany" doesn't seem to solve the problem.

Maybe it is helpful to mention my quartus install path?

it's

/opt/altera/quartus/

don't know if that's a problem?

maybe the resources that quartus tries to open using the specific browser are placed at a different path? if so what is the correct path and how to change it?

kind regards

I just found out this problem also exists for NIOS2 software!!

firefox cannot be launched as well?

I think this is the problem.

When I lauch Help/PDF Tutorials/PDF Tutorial for VHDL users, in Quartus, it opens firefox and the address is "file:///c:/altera/11.1/quartus/common/help/tutorial_quartusii_intro_vhdl.pdf". Then, verify if this file is in the same path "[...]/quartus/common/help"
