Hello All I am trying the install Oracle 11g on Linux. The server is $ uname -a Linux testsacx 2.6.9-55.ELsmp #1 SMP Fri Apr 20 17:03:35 EDT 2007 i686 i686 i386 GNU/Linux $ xhost+ testsacx $ export DISPLAY=testsacx:0.0 I start the runInstaller and get the following message Checking monitor: must be configured to display at least 256 colors >>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<< $ ls -l /usr/bin/xdpyinfo ls: /usr/bin/xdpyinfo: No such file or directory $ I searched in google for xdpyinfo and came up with [1]http://72.14.253.104/search?q=cache:g_aghAprJMcJ:t2-project.or g/packages/xdpyinfo.html+xdpyinfo+for+download&hl=en&ct=clnk&cd=1 1&gl=us I am not sure if this can be used in GNU linux. I will ask the SysAdmin to get this one setup. But i want to know if anyone has a better idea of attacking this issue. Thanks Govindan References 1. http://72.14.253.104/search?q=cache:g_aghAprJMcJ:t2-project.org/packages/xdpyinfo.html+xdpyinfo+for+download&hl=en&ct=clnk&cd=11&gl=us
