xrandr info when a 2nd VGA monitor is connected to secondary VGA output
Why do you write xorg.conf as below: Option "monitor-LVDS" "EXT" Option "monitor-TV-1" "EXT" What's your board type? So it has 2 VGA ports, and nothing to do with TV? Please also attach Xorg log according to http://intellinuxgraphics.org/how_to_report_bug.html (In reply to comment #3) > Why do you write xorg.conf as below: > Option "monitor-LVDS" "EXT" > Option "monitor-TV-1" "EXT" > What's your board type? So it has 2 VGA ports, and nothing to do with TV? > Please also attach Xorg log according to > http://intellinuxgraphics.org/how_to_report_bug.html I was trying to set Dual Head Mode for the system. Therefore I added these two options to test it out because there are 2 VGA ports. There is not intergated monitors but xrandr always shows that LVDS is connected. Whenever I connect a 2nd monitor to the secondary VGA port, xrandr shows that TV-1 is connected. After checking the i915GM block diagram spec., the 2nd VGA is activiated via a TV encoder CH7317A which is also known as sDVO. Hope this piece of info helps.

If you want cloned screen on 2 VGA monitors (as what I understand by Dual Head), you don't need set specific options in xorg.conf -- the driver is expected to light the 2 monitors and get them cloned automatically. The first issue here is LVDS is wrongly detected. So you can workaround it by adding monitor-LVDS in xorg.conf (as you did), and adding option "ignored" under monitor-LVDS section. On the other side we can see how to quirk it. Anyway, you can't set 2 monitors with the same identifier "EXT". So you can remove monitor-VGA and monitor-TV-1 related info from xorg.conf. Please upload new log and xrandr output with above change. (and remember to clear "NEEDINFO" from keyword field once you done) Hi, I wish too that there are less machines so that I could test less but it's not call :) Anyway, sorry guys that I had posted incomplete logs previously.

xrandr with verbose 2
It seems you didn't do this: The first issue here is LVDS is wrongly detected. So you can workaround it by adding monitor-LVDS in xorg.conf (as you did), and adding option "ignored" under monitor-LVDS section. Once you do that, please attach xorg.conf so I can check if it's correct. I'm not aware of an option "ignored" for the monitor section. I think it needs to be
# man xorg.conf
[...]
Option "Ignore" "bool"
This optional entry specifies that the monitor should be ignored
entirely, and not reported through RandR. This is useful if the
hardware reports the presence of outputs that don't exist.
(RandR 1.2-supporting drivers only)
Non existing options are more or less silently "ignored". ;-)
Stefan is right. The option should be "ignore". Sorry for my previous typo. Created attachment 20696 [details]
xorg.conf with ignore option in monitor section
I had added a new monitor section in the xorg.conf as shown below.
Section "Monitor"

HorizSync 30-61
VertRefresh 43-75
UseModes "Modes[0]"
EndSection
Not too sure if I had done correctly, but xrandr still shows LVDS is connected.
You need put monitor-LVDS under device section, like: Section "Device" BoardName "915 GM" Driver "intel" Identifier "Device[0]" Option "monitor-VGA" "Monitor[0]" Option "monitor-LVDS" "Monitor[1]" Option "ModeDebug" "yes" Screen 0 VendorName "Intel" EndSection Section "Monitor" Identifier "Monitor[1]" Option "Ignore" "yes" EndSection Created attachment 20711 [details]

xorg.conf
Hi, I will be following up on this issue while Shih Ming is away. I tried to follow this bug thread and recreate the xorg.conf as required but do let me know if I have missed out on anything. Ok, I have tried both Jesse and Zhenyu's patches separately. I downloaded the 2.5.0 source using git, applied the patches(original source used for each patch) using the patch -i <patchfile> command, ran ./autogen.sh, make and then make install. I then restarted the machine each time I installed the patched driver.
The bad news is that both patches did not seem to have an impact on the secondary display. The currently situation with either patches is that only the primary display can be seen while the secondary display is blank. I will be attaching the dmesg, Xorg.0.log and xrandr information for each patch.

Rom Binary
Hi Michael, here's the rom.bin file you requested.
I noticed the xorg.conf file you used is different in the Monitor[0] section. Did you changed the VGA monitor that connect to the primary VGA connector on the machine? I'm asking because it's weird in Shih Ming's log the VGA EDID is successfully retrieved from the machine, while in your log it fails. I don't think Zhenyu's patch has anything to do with that... I assume you are testing on the same machine as Shih Ming, right? Created attachment 21040 [details]
xandr --verbose
You are right Michael. I am using a different monitor from the one Shih Ming used but the same machine is used. I was using a 12" monitor as a primary and a 15" as secondary. With the same xorg.conf, I switched the 15" screen(the one I presumed Shih Ming used originally) to be the primary and the 12" as the secondary. Upon reboot, both screens now display a cloned desktop without distortion. I am attaching the logs again. But any idea why the dual display don't work when connected the other way round?

actually, even you exchange your monitor, the primary VGA still can't get EDID from the monitor attached to it.. I can't explain why in Shih Ming's test result , such as comment# 13, it can get EDID successfully, if the HW environment is the same... The Rom bin you attached indicate that the VGA should use GPIOC to do DDC, however, it still can't explain the log Shih Ming attached.

You would need to esccalate this issue to your HW team to double check this. A useful information for them is you once can get the EDID on the HW in comment# 13. However, this can work around this, as you can see, through xorg.conf to specify a modeline that works with the monitor. you could stay with this solution, too.

Michael, We had faced similar problem detecting IBM monitors before and I am trying to recify it using Novell recommanded tools currently. I will update you once I recieved a reply from our HW team. Hi Michael, The H/W folks have came back to me that there is a rework for our test unit regarding the VGA defect. Apparently, we are waiting for the new board to be shipped to us. I will test it immediately once I receive it. Thanks. There might be possible the monitor is broken without EDID info, I think that's common on older hw. As current problem looks only for VGA EDID missing issue, and we can always use default modes like 1024x768 on them. Origin problem has been fixed in bug# 18462, and patches are upstream now. So close this one. (In reply to comment #79) > There might be possible the monitor is broken without EDID info, I think that's > common on older hw.

With reference to comment #29, I added the patch to xf86-video-intel-2.5.0 to make it work where RC1 and RC2 have the dual display problem. Does the latest intel driver solve this bug? If it is already fixed, will be available in RC4? Lew, RC3 does not include Jesse's reorder patch, which prefers VGA instead of (possibly false) detecting TV output.

Is there any plan to make it available for the upcoming releases? Enabling the dual display is our current top priority to meet our machine GA date. Lew, I suggest to do further discussing in Bug #17823. |
