Description Nicolò Chieffo 2010-04-02 09:19:06 UTC

The problems I have are minor, and are highlighted by gnome-settings-daemon

Every time I open the laptop lid:
1) the first bulk of keypresses lag some seconds (no matter when I hit the
keys, it can also be 1 minute after I opened the lid) then the keyboard goes
back to normal work
2) some panel icons (apparently all applets) suddenly disappear and reappear
(like a flash). This does not always happen

Without gnome-settings-daemon running, everything is normal.

After having filed a bug to gnome-settings-daemon, developers discovered that some xrandr events are delayed until a key is pressed, and asked to file a bug to Xorg.

I hope that someone reads this message.

I watched the file /var/log/messages and I found this output

AFTER CLOSING THE LAPTOP LID:

Can you please tell me if you think that this problem is in xrandr, or in the kernel? Thanks

I don't see how this could be happening in xorg-server ... my guess is that it is kernel related.

Keith, can you comment?

Nicolo, are you still experiencing with newer kernels?  Can you attach system information:

lspci -v
dmesg
/var/log/Xorg.*.log
etc

Comment 3 Nicolò Chieffo 2011-05-29 02:37:16 UTC

Hello! The problem is that now when I close the lid my laptop suspends, and there's no more an option to disable this behavior.
Any help? (I'm running the developement version of ubuntu)

Comment 4 Nicolò Chieffo 2011-05-29 03:02:05 UTC

Hi back, I managed to remove the automatic sleep changing the dconf keys to "blank" instead of "suspend".
The bug is still present!

I'll attach the requested files

This just sounds like silly userspace...

However, one question I can easily google: http://askubuntu.com/questions/15520/how-can-i-tell-ubuntu-to-do-nothing-when-i-close-my-laptop-lid

And I'd be concerned about userspace crashing like that upon resume...

No evidence presented here for the delayed xrandr events.
