I need to start running a dual head on one of my machines. Eventual target is CentOS 5.x. Decided to test first on my 4.6 setup (eventually it will achieve 5.x). Both machines are fully up to date. The test machine is 4.6, 2 radeon video cards. Searched the web, CentOS site, even bugzilla. This bugzilla entry from a 4.2 system), http://bugs.centos.org/view.php?id=1875 had only a WFM response. I've attached a gzipped text file of pertinent information. Briefly, kudzu did the right thing when I installed the second card. System-config-display also behaved correctly. X start ok, but will only use one head at a time. Adding a second "BusID" so that both cards are explicitly addressed didn't help. When the 2 "BusID" entries are switched, the active screen doesn't move (it's always "Screen0") and the ignored screen ("Screen1") remains the same. The monitor attached to the video card for "Screen0" becomes the active one. Q1: Anyone have a two video card CentOS 4.6 setup working? Q2: Is it working in CentOS 5? Q3: Anyone see something I'm doing wrong? Suggestions? TIA, -- Bill -------------- next part -------------- A non-text attachment was scrubbed...
