X Crashes when enabling second monitor

[Steven Coutts]

Using Kubuntu, Lucid, with all latest updates applied.

When enabling my second monitor, either using xrandr from the CLI or from display settings in system settings, my X crashes, the following is printed in the X log -:

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in xorg.

[Luis Fernando Planella Gonzalez (luisfpg)]

Happens for me too.
If I plug the external monitor and set the netbook lcd to mirror the external monitor, things work ok.
However, if I set it to be on the left side of the external monitor, x crashes.
Using kubuntu lucid with all updates, on a netbook with an intel video (00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03))
After that crash, I'm set to 800x600, and if I try to restore the native 1024x800 resolution, X server crashes again.
I'm attaching the dmesg, lspci, lshw and Xserver.0.log files.

[Luis Fernando Planella Gonzalez (luisfpg)]

Maybe a duplicate of https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/555573 ?
I have the same "Fatal server error: Failed to submit batchbuffer: Input/output error" in my Xserver.0.log...

[Steven Coutts (scoutts)]

I get the exact same symtoms as Luis, except I don't get dumped to 800x600.

[Steven Coutts (scoutts)]

I also don't seem to get "Fatal server error: Failed to submit batchbuffer: Input/output" in Xserver.0.log

[Luis Fernando Planella Gonzalez (luisfpg)]

New info: it worked with an external monitor with 1280x1024 resolution.
The first monitor i've tried used 1680x1050, and perhaps was pushing the netbook's onboard video card too far...
As there are some new updates, I'll try again connecting with the 1680x1050 monitor, but I'll only be at that place tomorrow, and will report here the result.

[Luis Fernando Planella Gonzalez (luisfpg)]

Actually, following Murphy's law, I found the cause minutes after the last post...
But, at least I found how to reproduce it :)
I use KDE. If I disable compositing (shift+alt+F12), then the second monitor works without being mirrored.
With compositing enabled, X crashes, and happens as first reported.
On my previous post, the battery was low, so KDE disabled the effects. As a result, I thought it could be related to resolution.
But actually, it's related to the desktop effects being enabled or disabled.

Now, the real question: is this a limitation of the intel hardware / driver of not being able to handle dual head with compositing or is this a bug? Could someone using gnome test whether dual head works with compiz (desktop effects) enabled?

[Steven Coutts (scoutts)]

Ah excellent.

Disabling compositing allows to me use multiple monitors!

Well done Luis!

[Luis Fernando Planella Gonzalez (luisfpg)]

A colleague has a netbook with intel video, and he has lucid ubuntu netbook remix installed.
If he plugs an external monitor with dual head, the effects are automatically disabled.
This is way more elegant than just crashing :-)
I don't know if it's an ubuntu-specific or compiz feature, but KDE should also suspend compositing automatically when a second monitor is used in a dual head setup, at least for models which don't support it.

[deric (barton-tomas)]

Quite the same problem with Intel(r) 82945GM (Dell Latitude D620). Cloning display works fine but "exteded desktop" with enbled desktop effects always crashes Xserver

I can confirm #7 post behavior in Debian testing (squeeze) having KDE 4.4.3 and being up to date (21/5/2010).

[Luis Fernando Planella Gonzalez (luisfpg)]

I have created a bug report for the intel driver, as this seems driver specific: https://bugs.freedesktop.org/show_bug.cgi?id=28137
My first attempt was to report on KDE, but they stated (with reason) that the problem was the driver: https://bugs.kde.org/show_bug.cgi?id=237506

[Luis Fernando Planella Gonzalez (luisfpg)]

Things are working now: when enabling dual head, compositing is disabled (presumably by the intel driver, not KDE).
Can be marked as resolved by upstream.

[Carlos Corbacho (carlos.corbacho)]

I don't believe this is fixed, as I still see it on Kubuntu Lucid on an X60 (this is with xserver-xorg-video-intel 2:2.9.1-3ubuntu5). I have a Dell monitor plugged up that I'm trying to add as right of the X60 screen at 1280 x 1024:

I have Google Chrome installed. Interestingly enough, if I close that, then KDE seems less likely to crash when doing the resizing (may be unrelated).

Steven Coutts, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg-server REPLACE-WITH-BUG-NUMBER

Thank you for your understanding.
