User's Environment
When i run ./runInstaller -ignoreSysPrereqs , i got error message about Display environment.
Few months ago i had experience about installing Oracle on Linux SUSE(just made some tests) and when i had problem like this, someone said do this:
export LIBXCB_ALLOW_SLOPPY_LOCK=1
i did, then i saw GUI of OUI. it was ok.
Now it's not test one an i dont wanna do mistake.
i read from here section 2.14 http://download.oracle.com/docs/cd/B19306_01/install.102/b25293/pre_install.htm
