no screens found for IGP 320M

[Matthias]

on HP4300 laptop with ATI IGP 320M card, the current xserver-xorg-video-ati package fails to find the internal/LVDS screen. I've had to switch the MonitorLayout in the past but under Gutsy it doesn't detect it at all. Down grading to package from Feisty (xserver-xorg-video-ati_6.6.3-2ubuntu6_i386.deb) works.

dmesg output

[Matthias (matthias-opennomad)]

Is there any other information I can provide?

[Matthias (matthias-opennomad)]

i just upgraded the Hoary and the behaviour as changed slightly. Now the LVDS displays a partial screen. The resolution is set to 1280x768, while the LVDS only supports 1024x768. Any attempt to change this fails.

Here is the output from xrandr, which does not show the LVDS:

<pre>
# xrandr

Screen 0: minimum 320 x 200, current 1280 x 768, maximum 1280 x 1200

VGA-0 disconnected 1280x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

S-video disconnected (normal left inverted right x axis y axis)

  1280x768 (0x4f) 80.1MHz

        h: width 1280 start 1344 end 1480 total 1680 skew 0 clock 47.7KHz

        v: height 768 start 769 end 772 total 795 clock 60.0Hz

</pre>

The vesa driver still works as before and produces correct output on the LVDS

[Matthias (matthias-opennomad)]

So I kept on playing with it a little more with the default xorg.conf file, which produces the 1280x768 output on the LVDS.

Like I said the LVDS is still not being detected, but since X assumes a default screen size of 1280x768 on the non-attached external display I did some more experimentation and found that the following results in something useful on the screen with direct rendering enabled:

  # build a modeline - the following works for me
  gtf 1024 768 78.654
  # then use the output from above (everything after the word modeline)
  # to set the resolution of the non-existent external monitor
  xrandr --newmode "1024x768_78.65" 87.02 1024 1088 1200 1376 768 769 772 804 -HSync +Vsync

  xrandr --addmode VGA-0 "1024x768_78.65"

  xrandr --output VGA-0 --mode "1024x768_78.65"

I think it's still problematic that the LVDS is not detected, since it keeps me from running dual headed, but at least the laptop is semi-functional. I've attached the current xrandr output after the above tweaks.

Hi Matthias,

One thing that would be helpful is if you could test it against Intrepid (i.e., try booting an intrepid Live CD), and if it still isn't working, provide your /var/log/Xorg.0.log from that case. Then we can forward the bug upstream.

[Matthias (matthias-opennomad)]

Bryce, here is the Xorg.0.log as requested.

[Matthias (matthias-opennomad)]

output from xrandr which does not show the LVDS. The resolution also is "wide" and does not match the internal display

[Matthias (matthias-opennomad)]

it may not be related, but i've noticed under Hardy and Intrepid, totem does not like to go to full screen. under Hardy X dies altogether under Intrepid totem just dies with the attached output.

[Matthias (matthias-opennomad)]

and finally output from glxinfo if it may help.

[Matthias (matthias-opennomad)]

Bryce, I hope this is enough information to open an upstream bug. Let me know if you need more. I'd be glad to supply.

thanks

[Brian Murray (brian-murray)]

Thanks for taking the time to report this bug and helping to make Ubuntu better. In the development cycle for Intrepid there have been some vast improvements in the open source ati video driver and we could use your help testing them. Could you please download the latest Alpha CD image of Intrepid and test this particular bug just using the Live CD? You can find the latest image at http://www.ubuntu.com/testing . Your testing can help make Ubuntu and the open source ati driver even better! Thanks in advance.

Xorg.0.log from intrepid alpha 4

[Matthias (matthias-opennomad)]

Brian, i've attached output obtained from the latest alpha release (4) of intrepid. same 4 files as before: Xorg.0.log and output from xrandr, totem and glxinfo. Let me know if others are needed.

This release does appear to have bettered things a little. for example going to full screen under totem only crashes totem, rather than X completely.

The internal display is still not detected however and defaults are assumed for the non-existant external display, which shows up on the laptop screent.

I have the sneaking suspicion that this may be related to the totem crash, but no proof.

At any rate, this is a step in the right direction, but the latest alpha release does not solve original issue.

Let me know if I can provide further data or testing.

\@matthias

[Matthias (matthias-opennomad)]

i'm not sure that this is truly a duplicate of 269357. That bug largely deals with the 2ndary issue I reported of players crashing X.

The primary reason for this report was that the LVDS (internal laptop display) is not detected at all and I hacked around it, but the biggest issue is that the internal display is not found.

[Problem]
The LVDS on this system is not detected on the laptop. The external VGA can be made to work by adding modes to it.

[Original Report]
On HP4300 laptop with ATI IGP 320M card, the current xserver-xorg-video-ati package fails to find the internal/LVDS screen. I've had to switch the MonitorLayout in the past but under Gutsy it doesn't detect it at all. Down grading to package from Feisty (xserver-xorg-video-ati_6.6.3-2ubuntu6_i386.deb) worked. [But 6.6.3 is unavailable in Intrepid.]

I then upgraded to Hoary and the behaviour as changed slightly. Now the LVDS displays a partial screen. The resolution is set to 1280x768, while the LVDS only supports 1024x768. Any attempt to change this fails.

So I kept on playing with it a little more with the default xorg.conf file, which produces the 1280x768 output on the LVDS.

  xrandr --addmode VGA-0 "1024x768_78.65"

  xrandr --output VGA-0 --mode "1024x768_78.65"

I think it's still problematic that the LVDS is not detected, since it keeps me from running dual headed, but at least the laptop is semi-functional. [Here is] the current xrandr output after the above tweaks:

 Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1280 x 1200
 VGA-0 disconnected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768_78.65 78.7*
 S-video disconnected (normal left inverted right x axis y axis)

In Intrepid Alpha 4, the xrandr output looks like this:

Screen 0: minimum 320 x 200, current 1152 x 864, maximum 1360 x 1200
VGA-0 disconnected 1152x864+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
S-video disconnected (normal left inverted right x axis y axis)
  1152x864 (0x4f) 81.6MHz
        h: width 1152 start 1216 end 1336 total 1520 skew 0 clock 53.7KHz
        v: height 864 start 865 end 868 total 895 clock 60.0Hz

Still no LVDS...

possible fix

Does this patch fix the issue? If not please send me a copy of your video bios:
(as root)
cd /sys/bus/pci/devices/<pci bus id>/
echo 1 > rom
cat rom > /tmp/video.bios
echo 0 > rom

[Bryce Harrington (bryce)]

Hi Matthias,

I agree let's focus this on the LVDS issue.

I've forwarded this issue upstream to https://bugs.freedesktop.org/show_bug.cgi?id=18395. Could you please subscribe to that bug, in case upstream needs more info or wishes you to test something? Thanks ahead of time.

Oh, and also could you post the output of `lspci -vvnn`? We may need that so we know the exact PCI ID's of your video card and mother board.

[Matthias (matthias-opennomad)]

Here is the output of lspci -vvnn.

not sure how to subscribe to the other bug. Do I just add my email to the CC field?

Here is the requested BIOS. I'll see if I can give the patch a shot today.

improvised patch

I just built a new package based on the source for Ubuntu 8.04 (Hardy). The patch failed to apply against the 6.8.0-1 source release, but I improvised and applied the attached diff, which only adds the info->IsIGP to one line of the source I was working with. This appears to work and xrandr now produces:

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024

VGA-0 disconnected (normal left inverted right x axis y axis)

LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

   1024x768 60.0*+ 60.0

   800x600 60.3

   640x480 59.9

S-video disconnected (normal left inverted right x axis y axis)

WOoo Wooo. there is the LVDS!

Fixed according to upstream; should be available now in jaunty.
