Segmentation fault on X.Org when use pointing devices

[Alexander]

After my last reboot I can't start up my laptop. After login screen loading when I use any pointing device (internal touchpad or external mice) x-org will crash and go to console with no errors. If i don't use mice and typing password in login screen system try to load full environment but over a time it will crash to the console and after that load login screen.

In recovery mode it the same except if I not using mice it load full unity environment but if I try touch mice it still crash and go back to console and login screen after that.

Sorry for my english.

I see in backtrace (XorgLog.txt) this: /usr/bin/X (GetPointerEvents+0x430) [0x8088290]
Maybe it happens when last updates come. It updated many unity plugins.
How can I reanimate my laptop? I really need it to work.

[RussianNeuroMancer (russianneuromancer)]

Downgrade Xorg Server: sudo apt-get install xserver-xorg-core=2:1.10.4-1ubuntu4

[RussianNeuroMancer (russianneuromancer)]

By the way what PPA's do you use?

[Pogorelov Alexander (shurik2k5)]

I have a same bug fix it:
sudo apt-get install xserver-xorg-core=2:1.10.4-1ubuntu4.1

[Alexander (abonec)]

When i downgrade xserver (sudo apt-get install xserver-xorg-core=2:1.10.4-1ubuntu4) I can use mice in login screen and it no crash but after login it still crash and back to the login screen.
But safemode not loading even to the login screen. It going to infinity loop between trying show some gui to me and crash to back.

[Alexander (abonec)]

RussianNeuroMancer: for x-server i don't use ppa, but I use https://launchpad.net/~unity-2d-team/+archive/unity-2d-daily for unity 2d.

[Pogorelov Alexander (shurik2k5)]

Try to create new xorg.conf file:

sudo service gdm stop
sudo Xorg -configure
sudo mv xorg.conf.new /etc/X11/xorg.conf
sudo service gdm start

[Alexander (abonec)]

I made following:
sudo service lightdm stop (because it block Xserver)
sudo Xorg -configure
sudo mv ~/xorg.conf.new /etc/X11/xorg.conf
sudo service gdm start
And desktop was loaded but my touchpad working bad and desktoop seems weird. But after reboot i can't see my login page only wallpaper from it and sudo service gdm start is like it.

[Pogorelov Alexander (shurik2k5)]

try
sudo dpkg-reconfigure lightdm

[Alexander (abonec)]

After it and reboot login screen is black with mouse cursor. But if I type password and push enter it load white screen where should be loaded environment.

[Pogorelov Alexander (shurik2k5)]

Well...
try remove xserver-xorg and reinstall it:
sudo aptitude purge xserver-xorg
sudo apt-get install xserver-xorg-core=2:1.10.4-1ubuntu4.1

After reinstalling xserver-xorg the problem of missing.

[Alexander (abonec)]

I moved back my old xorg.conf and it work. Don't work how but it work. Thx you.

But i don't know what to do with updating. It seems like my laptop not compatible with new x-org

[Pogorelov Alexander (shurik2k5)]

I have buh on my desktop computer, but on my laptop version is good. I think this trouble in xorg and no depend on platform (desktop or laptop)... waiting xorg fixes.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Diomas (dmitriy-skopa)]

After last update, my ubuntu start crashing and kicking me to the login page each time I move or click the mouse. I tried both devises i have: PS/2 and USB - same result. I use unity-2d from ppa, but this crash happen even on the login screen (before any session is loaded).

Then I found the reason: http://askubuntu.com/questions/101308/xorg-segmentation-fault-seems-to-be-relevant-to-evdev

after I downgraded xserver-xorg-core to 2:1.10.4-1ubuntu4.1 the problem disappeared:
sudo apt-get install xserver-xorg-core=2:1.10.4-1ubuntu4.1

it seems "Fix crash on accepting a touch grab from an indirect device" patch broke my ubuntu.

[Alexander (abonec)]

After all of this my laptop don't want to sleep. When I close lid it seems like going to suspend (led-indicator on the laptop start blink such as laptop suspended) but when I open login screen is appear. It seems like X-server crashed and go to the login page.
But in don't know where I can find log with error or backtrace.

[Alexander (abonec)]

Strange is that when I choose "suspend" from menu it work normal but if I just close lid laptop going to the being suspend but when it wake up login screen is appear (like x-server was crashed)

In config set to suspend when closing lid in both cases (from battery and AC).

Alexander, 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

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
