<div>it seems a workstation card, there are 3 solutions you could try.</div> <div>1. run two commands in console mode,</div> <div>"aticonfig --initial=dual-head"</div> <div>"aticonfig --xinerama=on"</div> <div>if the two commands are successful, your xorg.conf should has the same sections with attachement.</div> <div> </div> <div>2. use one monitor to startx and connect another, and then configure xinerama by command "amdcccle", this command could provide a friendly GUI to you. <br></div> <div> </div> <div>3. don't use xinerama, just run the command to achieve a single desktop spanning the two, run "aticonfig –dtop=horizontal".</div> <div> </div> <div>Cooper</div> <div><br> </div> <div class="gmail_quote">On Fri, Sep 25, 2009 at 1:22 PM, Dan Engholm <span dir="ltr"><<a href="mailto:mustang@engholm.org">mustang@engholm.org</a>></span> wrote:<br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Dear list,<br><br>I have a PC with an ATI FireGL V3400 display adapter. It has two flat panel LCD monitors connected via DVI and I want to set it up with a single desktop spanning the two. After some research, I figured that I had to install the ATI proprietary driver to get the Xinerama extension for this card so I got it and installed it with no apparent problems. Unfortunately, aticonfig reports that it cannot find suitable hardware so I had to configure the server by hand. I found that it works just fine with Clone on and Xinerama off but if I reverse the two, the server crashes with this in the log:<br> <br>Backtrace:<br>0: X(xf86SigHandler+0x71) [0x48e8f1]<br>1: /lib64/libc.so.6 [0x3b2b6302d0]<br>2: X(xf86RandR12CreateScreenResources+0x38e) [0x4b7c0e]<br>3: X [0x4b1d3f]<br>4: X(main+0x2e5) [0x4333b5]<br>5: /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b2b61d994]<br> 6: X(FontFileCompleteXLFD+0x229) [0x4327f9]<br><br>The driver says this of the adapter:<br>(--) R500(0): Chipset: "ATI FireGL V3400" (ChipID = 0x71d2)<br><br>I could not find any driver version information in the log but I just downloaded it from AMD on the 15th. The installer's filename is ati-driver-installer-9-9-x86.x86_64.run.<br> <br>If anybody has any ideas on how to get around this problem, I would appreciate hearing them. Other information is available upon request.
