Description Eric Zhang 2009-04-21 07:44:01 UTC
Created attachment 24999 [details] including xorg.conf, Xorg.log.0(ModeDebug enabled), uname, dmesg, package infos I have a G43 chipset with x4500 display card embedded. Using xf86-video-intel 2.6.x, DVI(DVI-D) display can't be opened so the X server can't start. Check the attachment for details. It includes xorg.conf(ModeDebug enabled), Xorg.log.0, uname outputs, dmesg, xrandr --verbose outputs and package infos. I have installed the xf86-video-intel 2.7 version today but it still doesn't work. I'm looking forward to your patches, otherwise I can't start my work under Linux. :)

I wished you really go through http://intellinuxgraphics.org/how_to_report_bug.html and not use zipped attachment. What's your G43 motherboard model? Does it have VGA port?

Created attachment 25024 [details] please try the patch on your machine, thanks. I guess the issue is duplicate with bug #20429, so please try the debug patch. thanks maling
Comment 5 Eric Zhang 2009-04-22 07:28:02 UTC
Created attachment 25034 [details] New error log With no lucky, seems the patch doesn't work. Here's the new Xorg.0.log file.
Comment 6 MaLing 2009-04-26 23:07:29 UTC
Created attachment 25174 [details] please try the patch on your machine, thanks. the reason is from incorrect hdmi detection, please try the patch on your machine. thanks maling
Comment 7 Eric Zhang 2009-04-27 08:00:09 UTC
Created attachment 25188 [details] New error log, xorg.conf is attached on the bottom of file Still unlucky, the X can't start again. My step is: 1. download xf86-video-intel 2.7.0 source from git 2. cd source dir, patch the source: patch -p1 < 21322_debug.patch 3. ./autogen --prefix=/usr 4. make 5. make install -- check the file under /usr/lib/xorg/drivers/intel are updated 6. Xorg -configure -- generate a xorg.conf.new in /root 7. Edit /root/xorg.conf.new, turn on ModeDebug, add DefaultDepth 24, Modes "1440x900" 8. X -config /root/xorg.conf.new -- X started failed BTW: I tried to patch these 2 patches, the result is also failed. The error log attached is the version I only patched 21322_debug.patch on the source.
Comment 8 MaLing 2009-04-27 19:17:56 UTC
Created attachment 25210 [details] please try this debug patch on your machine, then upload log with modedebug option on, thanks. Meanwhile please provide the vbios dump via: # cd /sys/devices/pci0000\:00/0000\:00\:02.0/ # echo 1 > rom # cat rom > /tmp/rom.bin # echo 0 > rom then submit the rom.bin here. thanks for your help. maling
Comment 9 zhao jian 2009-04-28 00:34:32 UTC
Maybe you could have a try of plug your display port again, make sure it has connected tight enough. I have the same issue and just reconnect the HDMI and it works well now.
Comment 10 Eric Zhang 2009-04-28 07:22:48 UTC
Created attachment 25228 [details] Xorg.0.log Hi, guys. Here comes the good news. The X started successfully after this new patch has applied. And now my KDE works well too. Ma Ling, as you mentioned, I uploaded this new Xorg.0.log, check it. Thanks for your hard work. Also thanks to Zhao Jian, but obviously this is not because the DVI cable isn't plugged well. I installed windows in my machine and the DVI outputs work well under windows all the time. I think maybe this is a temporary patch so, if any tests or other stuffs are needed to perform, just feel free to let me know.

Comment 17 MaLing 2009-05-25 05:50:09 UTC
hi Eric I have similar motherboard with you --Asus P5Q-EM, ATX. Today I encountered the same issue, but after I turned off system, pluged HDMI cable out of machine, and re-pluged it, then reboot system, the issue disappeared. Could you help us to try the above process? Thanks for your help Ma Ling
Comment 18 Eric Zhang 2009-05-28 19:02:18 UTC
Hi, Ma Ling: I tried the method you mentioned, the result is: failed. Here are my steps: 1. Compile and install the xf86-video-intel 2.7.0 with the latest patch you provided. 2. Re-plug the DVI cable and reboot the system. The X started failed. 3. On the command line, re-plug the DVI cable, and test with "X -config /etc/xorg/xorg.conf", the X started failed. Any other ideas? Thanks a lot. Eric
Comment 19 MaLing 2009-06-08 23:13:37 UTC
Hi Eric The issue is very strange to me, now I can not reproduce it in Asus P5Q-EM platform, so would you please like to download our latest driver from master tree, then try it? Thanks for your help. Ma Ling
Comment 20 Gordon Jin 2009-06-09 15:37:09 UTC
I'm confused. Since there's a patch working as comment#10 said, why does ling need Eric to try master?
Comment 21 MaLing 2009-06-09 18:18:00 UTC
(In reply to comment #20) > I'm confused. Since there's a patch working as comment#10 said, why does ling > need Eric to try master? The patch in comments #8 is only debug patch to confirm the issue, it is not really resolved. And several days ago I could reproduce it in Asus P5Q-EM platform , but now it always work, so I suggest Eric to update his driver from our master tree. Thanks Ma Ling

The patch is hard code , in fact it can not dynamically detect hdmi connection, we can not accept it.
Comment 24 MaLing 2009-06-11 01:45:24 UTC
Created attachment 26663 [details] Eric, please try the debug patch against latest driver Based on HDMI spec each HDMI source should provide HDMI identity, which is stored in CEA extension, otherwise we may think it is not HDMI device. So we also can detect HDMI device by trying to fetch EDID. Thanks for your hellp. Ma Ling
Comment 25 Eric Zhang 2009-06-14 06:20:04 UTC
Hi, Ma Ling. Sorry for the late reply. It's a good news. Test passed. Here is the details: 1. I downloaded the latest master branch source codes, compile and install. But when starting X server, it failed. 2. Then I patched the patch you provided and tried again, this time it works. Great. Thanks for your hard work. You did a great job. By the way, should I close this bug? Eric Zhang

(In reply to comment #28) > *** Bug 22497 has been marked as a duplicate of this bug. *** Hello Ma Ling, I have tried you patch but without success. This is what I have done 1. git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-intel 2. patch -p1 -i ../hdmi_detect_edid_debug.patch patching file src/i830_hdmi.c Hunk #2 FAILED at 172. Hunk #3 succeeded at 212 (offset 8 lines). 1 out of 3 hunks FAILED -- saving rejects to file src/i830_hdmi.c.rej The patch did not apply cleanly but I looked through i830_hdmi.c and compared it with the changes that the patch should apply and everything looked okay. 3. ./autogen.sh --prefix=/usr make make install 4. I also checked that the files in /usr/lib/xorg/modules/drivers/ are new. -rwxr-xr-x 1 root root 985 2009-06-29 20:07 intel_drv.la -rwxr-xr-x 1 root root 3,4M 2009-06-29 20:07 intel_drv.so After restarting the system with my DVI cable pluged in the error still persists (VGA cable was not unpluged).

Created attachment 27263 [details] pleaset try the patch on your machine, thanks. this is a only dummy patch, please try it and upload your xorg log file with modedebug optoin on in UMS. Thanks Ma Ling
Comment 33 Achim Frase 2009-06-30 06:29:57 UTC
Created attachment 27265 [details] Xorg.log with debug.patch I hope the log has the necessary information. I was not sure what UMS is. I couldn't find any information at the freedesktop.org/wiki.
Comment 34 Geir Ove Myhr 2009-07-01 19:39:43 UTC
I'm guessing UMS means Userland ModeSetting (as opposed to Kernel ModeSetting). From the device names in Xorg.0.log it looks like you are using KMS (DVI1 instead of DVI-1). Using UMS can be done like this (taken from ubuntu: https://lists.ubuntu.com/archives/ubuntu-x/2009-June/000578.html) How do we revert back to non-KMS? Boot the kernel with the option i915.modeset=0 on your kernel command line. The ModeDebug part is supposed to go in xorg.conf. Add the following line to the "Device" section in xorg.conf: Option "ModeDebug" "true"
Comment 35 MaLing 2009-07-02 02:57:34 UTC
Created attachment 27330 [details] pleaset try the patch on your machine, thanks. Thanks for Geir Ove Myhr's exact reply ! The patch is dummy code, which will return connect status for HDMI output. please try it in UMS and upload log file with modedebug option on. Thanks Ma Ling

Created attachment 27339 [details] Xorg.0.UMS.2.6.30.log Thanks Geir Ove Myhr and Ma ling for your advice. I hope that I have done everything right this time. Regards Achim
Comment 37 Mahmut Izci 2009-07-02 14:46:41 UTC
(In reply to Bug 22497) (DVI port not detected on MSI G45M Digital motherboard) I switched off KMS (as Geir Ove Myhr mentioned) and applied this patch "http://bugs.freedesktop.org/attachment.cgi?id=26663" to 2.7.1 and now it works!! DVI port is detected. Xorg.0.log with debug option enabled is attached. But this patch still not works with KMS. Another possible solution to the problem is using an additional DVI port on an ADD2 card. This works without patch and even with KMS. Thanks and Regards Mahmut
