We just installed the latest Oracle Solaris 10 Sparc 64-Bit CPU patch (10/2012) and we are no longer able to access the GUI or the console after the OBP. We believe that this is a graphics issue. It has affected out t2000 xvr-200 graphics server and also out v440 xvr-100 graphics server.
We are still able to login remotely via ssh/telnet but we cannot login directly via the console or through the gui (monitor or kvm).
On the T2000 we are getting a white screen with black distorted lines and on the v440 we are getting an error 'The X-Server can not be started on display:0'.
We have tried to rollback and remove patches that has anything this to do with graphics. We have added packages and rm packages. We have tried to install the original xvr -x00 graphics disc that came with the servers but no luck. We have also contacted Oracle support and they have had us install a few packages and patches but still no luck. We have tried to adust the framebuffer with just about every resolution possible. We have also tried to disable the dtprofile to see if it will go straight to the console.
If there are any suggestions, please feel free to chime in. Also, if anyone has patched a t2000 or v440 , v880, or v120 with th latest CPU patchset (10/2012). Let me know if you are able to access the oracle solaris login gui or the console.
