Dear All, I have managed perfectly fine to install centos 5.5 x64 on a new sun blade x6270 server module .i had to install in text mode since GUI install mode was not working Actually this machine is going to replace my current working very low hardware server the server is used as my primary dns, mail server , webmail server also running Mailscanner, mailwatch etc. Also I want to use this new sun blade server as a virtual machine using xen i have installed xen and uts fine but i have a issue with the diplay driver I did run system-config-network and selected the card as ast-ASpeedTech chipsets since my lspci says i have a 20:05.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 10) now I run startx and i get the below error X Window System Version 7.1.1 Release Date: 12 May 2006 X Protocol Version 11, Revision 0, Release 7.1.1 Build Operating System: Linux 2.6.18-53.el5 x86_64 Red Hat, Inc.
