Hi, I've got a problem here that is 100% repeatable, however, not much logging information is available due to the nature of the problem which causes the OS to hang and requires a hardware reset of the machine to recover. The symptom occurs when I have 2 LCD flat panel displays connected to mmy ATO Radeon video adapter, and the Xserver runs in Xinerama mode. The primary LCD display is connected to the DVI port and runs at 1920x1200. The secondary LCD display is connected to the VGA port **via a KVM switch** and runs at 1600x1200. In this configuration, if the secondary display is not "connected" to the Xserver when it starts up, the machine totally hangs. This can occur if (for example) the KVM switch is connecting the display to another machine, or, if the display is switched off. The problem thus seems to be due to the inability of the Xserver to recieve EDID and/or DDC information for the secondary screen. I have tested the same configuration on Windows XP, and the Windows radeon driver doesn't have a problem if the secondary screen is switched off or is switched (via the KVM switch) to another machine. Thus it seems like the problem may be in XFree86 radeon driver. Here is my system information: XFree86: v4.5.0 Video card: ATI Radeon 9800XT, 128Mb memory, AGP bus Primary (DVI) port: Eizo FlexScan S2410W LCD flat panel display Secondary (VGA) port: Samsung SyncMaster 213T LCD flat panel display OS: Solaris 10 x86 (Generic_118844-26) Server hardware: ASUS NCCH-DL dual 3Ghz Xeon motherboard, 2GB memory I have attached /etc/X11/XF86Config-4 and some recent log files. Please let me know what else I can do to help isolate and/or identify the cause of the problem. Best regards, NickAttachment: XF86Config-4
