Xorg won't start on a laptop with 855GM (no valid mode)

[Antonio Riva]

Using lastest Intrepid, after some update, my laptop can't load the xserver with the laptop monitor. I use the default clean xorg.conf

The errors are:

(EE) intel(0): Output LVDS enabled but has no modes
(EE) intel(0): No valid modes.
(EE) Screen(s) found, but none have a usable configuration.

If I attach an external monitor gdm Xorg starts with no problem.

Using xrandr I get:

xrandr: Output LVDS is not disconnected but has no modes

So you had it working on intrepid before the updates?

[Antonio Riva (antonio-riva)]

I can't tell you fore sure because I've made the installation with the external monitor and only after a cupple of week I've noticed the problem.

[Antonio Riva (antonio-riva)]

Today I've tried with the last intrepid alpha6 livecd, the problem is steel here.

Making some more investigation seem to be related to the failure on the display detection.

with the external monitor attached the xresprobe command output:

id: SDM-HS95
res: 1280x1024 1280x960 1024x768 832x624 800x600 720x400 640x480
freq: 28-81 48-75
disptype: lcd/lvds

whitout this monitor attached the output is:

id:
res:
freq:
disptype: lcd/lvds

executing the get-edid | parse-edid command I received this error

parse-edid: parse-edid version 1.4.1
parse-edid: IO error reading EDID

here a portion of the $ sudo lspci -vvnn command output:

Ahm, with Ubuntu 8.04 and previews version, the problem didn't appear.

[Teo (teo666)]

I can confirm this bug.
Same problems here..
If you need more infos tell me!
Teo.

[Teo (teo666)]

The driver used in xorg.conf is "intel", not "i810" as indicated in the title..

[Karol Swietlicki (magotari+ubuntu)]

I'm in a rather unusual situation here, not even having Ubuntu installed, but I think I have some new information.

I'm a Gentoo user, and I have this problem too. The bug is strictly depending on one of their packages, x11-drivers/xf86-video-i810. The last version of the package that works is 2.3.2 and the first that I can confirm as broken is 2.4.1. I have no idea about 2.4.0. I updated my system today, and with 2.4.2 the problem persists. I'm still using 2.3.2.

Hope this helps. Not having Ubuntu there is nothing more I can do, but I hope this narrows things down a bit.

I can confirm this bug with a FSC Amilo 7400 laptop (also having Intel 82852/855GM) since the X 7.4->7.5 migration.

Is there any fix in sight? Information needed?

[Geir Ove Myhr (gomyhr)]

Teo, I changed i810 in the title to 855GM.

[carlsholmberg (carl-holmbergarna)]

I have exactly the same problem on my wifes FS Amilo M7400.
Se forum-post for more information.

[bgrupe (bgrupe)]

The most recent intel driver update (xserver-xorg-video-intel (2:2.4.1-1ubuntu8) intrepid) has fixed the issue for me, thanks.

[carlsholmberg (carl-holmbergarna)]

The update fixed it for me as well. Great!

[Geir Ove Myhr (gomyhr)]

The last update that fixed this was a bug fix for bug # 274045.
Setting this to Fix Released - hope that is the appropriate action. Antonio, feel free to reopen if you still have problems.

[Teo (teo666)]

Bug fixed also for me!!
Thanx, Teo.
