X Server problem

I’m trying to get Altera Quartus II software working on my notebook (with Open Suse 11.3), but the terminal printout indicates:

altera_installer_gui: cannot connect to X server

How can I solve this problem ?

P.S. In my opinion problem is in DISPLAY environment variable, but i can’t solve it.

sorry for my english :shame:

xhost + local:

evired@linux-31pf:~> echo $DISPLAY
evired@linux-31pf:~> xhost + local:
non-network local connections being added to access control list
evired@linux-31pf:~> /home/evired/10.0_quartus_linux/setup

Starting GUI. If nothing shows up, or you don’t have an X display, run:
./setup --help
for commandline usage.
NOTE: All output has been redirected to /tmp/altera_setup.log

After that GUI dont start

This is my installation log (altera_setup.log file):

Fontconfig error: “conf.d”, line 1: no element found
Fontconfig warning: line 73: unknown element “cachedir”
Fontconfig warning: line 74: unknown element “cachedir”
altera_installer_cmd: symbol lookup error: /usr/lib/libXi.so.6: undefined symbol: XESetWireToEventCookie

I found the solution on this page:
