current xorg.conf (almost empty, only virtual is defined)
This looks like a bug in the expertise of yakui.zhao@intel.com so reassigning. -Carl Will you please try the Eric's drm-intel-next tree and add the boot option of "drm.debug=0x06"?
After the system is booted, please plug the VGA cable and see whether it is detected as TV.
After the test, please attach the output of dmesg, xorg.log.
Please also attach the output of vbios.dump. The vbios.dump can be obtained by using the following commands:
a. echo 1 > /sys/devices/pci0000:00/0000:00:02.0/rom
b. cat /sys/devices/pci0000:00/0000:00:02.0/rom >vbios.dump
c. echo 0 > /sys/devices/pci0000:00/0000:00:02.0/rom
The Eric's drm-intel-next tree can be obtained by using the following command:
1. git clone git://git.kernel.org/pub/scm/linux/kernel/git/anholt/drm-intel.git
2. git branch -r
3. git checkout -b origin/drm-intel-next
Thanks.

Hi Yakui, I'm having problems installing eric's package: - I have performed step 1 - at step 2, I get the error: root@lb-u:~/xorg-video-intel# ll total 4 drwxr-xr-x 24 root root 4096 2009-11-18 13:38 drm-intel root@lb-u:~/xorg-video-intel# git branch -r fatal: Not a git repository (or any of the parent directories): .git Thanks ok, before I did cd drm-intel/ and git branch -r didn't said any problem, so I'm continuing the test ... Hi again, I did the step 3 checkout, now what to compile/install? I'm running ubuntu karmic koala, so I'd like to just compile the intel driver, not the whole linux, with minimum depencies, since I may be missing many of those .... Thanks again (In reply to comment #8) > Hi again, > I did the step 3 checkout, > now what to compile/install? > I'm running ubuntu karmic koala, so I'd like to just compile the intel driver, > not the whole linux, with minimum depencies, since I may be missing many of > those .... > Thanks again It seems that the system works in KMS mode. In such case you will have to compile the linux kernel. Will you please try to compile the linux kernel and attach the output of dmesg by adding the boot option of "drm.debug=0x06"? Will you please attach the output of vbios.dump as required in comment #5? Thanks. Created attachment 31434 [details]
dmesg detail with error regarding video card loading
Looking at dmesg, I've seen the errors attached in the log file, which may give some indication of what is happening.
Hi, - I have attached some errors messages I have seen in the dmesg, which can give some extra info of the problem - it's a little difficult for me to recompile the kernel; can you please give me some indications, links where to find the info to install the DKMS environment or whatever it is? Thanks (In reply to comment #11) > Hi, > - I have attached some errors messages I have seen in the dmesg, which can give > some extra info of the problem > - it's a little difficult for me to recompile the kernel; can you please give > me some indications, links where to find the info to install the DKMS > environment or whatever it is? > Thanks Will you please attach the vbios.dump required in comment #5? Thanks. Hi ykzhao, many thanks for your help. As I mentioned in my previous comment #11, it is a little difficult for me to recompile the kernel, since I'm using stock ubuntu 9.10. Is there any other way to give you the info you require, without recompiling the kernel? Is there any other ubuntu-style software source that I can setup in my computer to have the patch you are talking about installed? Thanks in advance.

If you can't complie and install the kernel, you can add the boot option of "drm.debug=0x0e" and attach the output of dmesg. Thanks. > > Thanks in advance. > Created attachment 31651 [details]

dmesg - external monitor connected before boot
(In reply to comment #17) > Created an attachment (id=31653) [details] > dmesg - external monitor connected before boot > Hi, Zmiq From the log in comment #16 it seems that there exists the SDVO card. Sometimes it is detected as SDVO-TV. Sometimes it is also detected as SDVO-VGA. Will you please add the debug option of "modedebug" in xorg.conf and attach the output of Xorg.0.log? Please boot the system with KMS disabled by adding the boot option of "nomodeset". > option "Modedebug" "True" Of course it will be great if you can compile the latest Eric's drm-intel-next tree and attach the output of dmesg by adding the boot option of "drm.debug=0x06". Thanks. Created attachment 31925 [details]
xorg.0.log - external monitor connected after logged into X
Hi ykzhao,
- it is very difficult for me to recompile the kernel; this is a umpc, with limited disk space, and I'm using stock ubuntu...
- with Option "Modedebug" "True", and nomodeset kernel option, now, when plugging the external monitor it gets correctly recognized, and resolution and refresh rates are OK !!
I have attached the xorg.0.log file as requested.
Thanks again for your support.

xorg.0.log - external monitor connected before boot
With the nomodeset option in the kernel boot, and having the external monitor connected before boot the system correctly recognized the external monitor, as expected.
I also feel the graphics very snappy, so I even activated compiz and the system is very responsive; also, some little flickering I used to see when using ubuntu 9.04 is not there anymore, now the image is very clear!
Thanks
Created attachment 32277 [details] [review] Detect SDVO S-video after SDVO RGB Will you please try the debug patch on the latest linus tree and see whether the issue still exists? Please add the boot option of "drm.debug=0x06" and attach the output of dmesg. thanks. The tip of the day on drm-intel-next kernel should fix this. would you please have a try? Hi Michael, which is this tip? This week I just upgraded to latest ubuntu, lucid lynx, and the problem got worse when I activated the x-swat ppa updates. Current status is that the problem is back: Prior to this update, setting the option 'nomodeset' in the kernel worked very well, but this 'trick' doesn't work anymore. 1) Booting with 'nomodeset' in kernel, and external monitor plugged in: the computer goes into 'low graphics mode' only (800x600), and no way to change, and doesn't detect the external monitor 2) Booting with 'nomodeset' in kernel, external monitor disconnected: error appears: 'No kernel modesetting driver detected. Screen found, but none have a usable configuration', and it goes into low-graphics mode After connecting external monitor, xrandr doesn't detect anything 3) Booting without 'nomodeset', and external monitor plugged in: it goes into 800x600 resolution for the built-in lcd (which is 1024x600), external monitor not detected 4) Booting without 'nomodeset', external monitor disconnected: built-in lcd works ok; after connecting the external screen (dell p1920), it detects it as TV1, with maximum resolution of 1360x768; then grabage appears in both screen until I turn off built-in lcd and activate only external monitor. I'm currently working with my external 1900x1200-able monitor at only 1360x768, but I can see something. I'd very much appreciate any help on this, since this issue is quite old, but still unresolved .... Many thanks in advance Hi Will you please try the latest Eric's drm-intel-next tree and see whether the issue still exists? thanks. Hi, as I said before, my compile abilities are limited. Is there any software source that I could activate in order to try this "Eric's drm-intel-next tree" using normal ubuntu software install tools? Thanks Looks like a dupe of 26833. Should be fixed now; there's an xorg edgers repo for bleeding edge kernels you could try. Check launchpad or ubuntu irc channels for help there (#ubuntu-x on freenode is a good one). *** This bug has been marked as a duplicate of bug 26833 *** |

Created attachment 31227 [details] lspci -vv detail I have a fujitsu u810 just upgraded to ubuntu karmic. I usually work with an external dell 24'' monitor (1920x1200), while lcd is 1024x600.
