I am using Sandy Bridge CPU onto X9SCL(-F)/X9SCM(-F)/X9SCA(-F)/X9SCD-F motherboard and installing with RHEL/CentOS/Scientific Linux 6.0 version. During or after the installation, my screen turns to black and seem no display at all. I tried to use nVidia display and does not see such problem. Any reason?
For using the display from Sandy Bridge CPU, please use RHEL/CentOS 6.1 version for support. Here is the release note indicated the fix for this matter. Customer can also upgrade the driver to patch the problem for second option.
