system-config-display unable to configure dual monitor
Last modified: 2007-11-30 17:10:44 EST
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Galeon/1.3.14 Description of problem: I'm unable to configure dual monitor using the "Dual Head" feature of s-c-display. The "Seconda Video Card" is empty, but I don't have a second video card, I have a single AGP video card with dual output (one VGA, one DVI), like most videcards in the market today. I tried with a Radeon 9600xt and a Geforce 5600xt, and the problem is the same. Only, with the GeForce, in the "Second Video Card" drop down, the name of the card appears, but nothing is done. Configuring dual head by hand on the Radeon works. I had no success with the GeForce tough. Version-Release number of selected component (if applicable): system-config-display-1.0.14-1 How reproducible: Always Steps to Reproduce: 1. Install FC2 2. run s-c-display 3. Actual Results: No possibility to enable dual head Expected Results: Having dual monitor is more and more common (and *very* useful), it should be supported out of the box Additional info: xorg-x11-6.7.0-2
Can you attach the xorg.conf file before and after configuring dual head? Unfortunately I don't have either of those cards so it's difficult to reproduce this problem. Dual head configuration works ok for me with my Matrox G450 dual head card.
On my system, with a ATI Radeon 9600 XT, I get the following problems: - s-c-d says: "Trying with card: VESA driver (generic)" instead of detecting correctly the card. - if I try to choose the card "by hand" on the Hardware page of s-c-d, the 9600SE is not listed - in the Dual Head page the "Second Video Card" drop down is empty so I can't enable dual head and press "OK" to confirm These are the relevant outputs from lspci and lspci -n: 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AQ [Radeon 9600] 01:00.1 Display controller: ATI Technologies Inc RV350 AQ [Radeon 9600] (Secondary) 01:00.0 Class 0300: 1002:4151 01:00.1 Class 0380: 1002:4171 I don't have the system with the geforce FX handy, I'll test it in the next days. P.S: Radeon is cheap... if I can afford it, I suppose redhat can afford it :) it's a *very* commond videocard in Italy (on newer pcs)
Created attachment 101417 [details] I Attach a working dual head xorg.conf hacked by hand for the benefit or other users facing the same problem This configuration file configure xorg with the following options: - radeon driver - two flat panels at 1280x1024 true color - individual desktops
I have a dual-head Cirrus Logic GD5480 card that has the same problem as reported above. I ran the command from the command line like so: /usr/bin/system-config-display -v Here is the output that I received, including an ERROR: Read configuration file /etc/X11/xorg.conf Trying with card: Cirrus Logic GD5480 in hydrate_second Traceback (most recent call last): File "/usr/share/system-config-display/xConfigDialog.py", line 208, in ok primaryPCIBus = "PCI:%d:%d:%d" % (self.state.get_videocard_PCIBus(), TypeError: int argument required
I forgot to mention that this is with FC3.
Consolidate to single bug - I hope to have a new package for testing Monday. *** This bug has been marked as a duplicate of 136916 ***
