Arch Linux

Probably should mention that I am running Arch64 on a Gateway NV79C with Intel Integrated Graphics.

Reported upstream as I doubt this is Arch-specific. https://bugzilla.gnome.org/show_bug.cgi?id=673585

This is the response I got from a GDM developer Ray Strode upstream.

This isn't likely to be a GDM bug. It sounds like an X driver issue of some
sort. Filing with your distribution was appropriate. Alternatively, you can
file an upstream report at bugs.freedesktop.org.

If it's not GDM that's crashing, it's probably X that crashes. Attaching Xorg.0.log(.old) would be nice.

I am away from my computer for a couple of weeks but hopefully drtillberg can post theirs.

Actually I think I might indeed be a gdm issue because I remember that when I would unplug the hdmi cable on gdm login I would get an oops/error pop-up like the ones you get when you login and it tells you one of your extensions is the problem and I fills the whole screen.

Had to come home from trip but at least I can help and try to squash this bug again. I am testing on my fake 720p tv (1360 x 768) and it is yielding different results. I can unplug the hdmi cable and use my desktop without the freezing but if I plug it in AGAIN the config is loaded properly and I have the top bar on the tv but when I unplug it AGAIN I get a black screen with a half cursor on the edge of the laptop screen and computer needs hard shutdown. This only happens after unplugging it the second time EVERY TIME. I will also mention that on my two 1080p tvs on forced reboot (me holding down the power button) I get an monitor config error logging in it says something like: unable to apply monitor configuration settings line 1 char 1 whitespace but not on the 720p tvs. All three tvs are samsungs no more than three years old.

Someone else with a similar setup is having the same problem. See here: https://bbs.archlinux.org/viewtopic.php?pid=1085815.

Having the exactly same problem.

I already heard from Debian guys that this issue might me related to intel vga driver + xorg.

I wasn't having this issue before reinstalling my arch recently with the most updated packages (`pacman -Qs` attached -- just in case anyone wants to know)

Could this be marked confirmed.

Bug supposedly fixed upstream. An Archer already reported here:

https://bugs.freedesktop.org/show_bug.cgi?id=47395

I am having trouble with dual monitor, too. My entire system crashes when I plug my monitor in my laptop via VGA and configure the monitor to be left of my laptop.

still having trouble

If the upstream bug at Freedesktop.org mentioned in the comments is the cause of this problem, this should be fixed in xf86-video-intel 2.18.0-3.

Not fixed for me. Looks like the same error as before.

i did pacman -U for the intel package. my mirror had xorg-server 1.12.1-2 though.

For me too nothing changed after updating to the xf86-video-intel 2.18.0-3 -- actually I also did a `pacman -Syu`

Curiously, my .xsession-error is empty.

I have posted a workaround on launchpad: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/921236?comments=all. My workaround was tested on Arch and Ubuntu 12.04. There is also a workaround here: https://bbs.archlinux.org/viewtopic.php?id=137593 that I have not tried.

Same bug, but with one monitor and nvidia card(proprietary driver) and two sets of mouses and keyboards. (i686 arch)
One set is ps/2 mouse and keyboard, and with this set all OK.
With two set A4Tech Mouse + Keyboard linked to PC by one usb dongle, Xorg crashes in Minecraft when i press "E" button (to open inventory).
Errors in Xorg:
[ 215.600] BUG: triggered 'if (!dev->valuator || dev->valuator->numAxes < 2)'
[ 215.600] BUG: getevents.c:845 in scale_to_desktop()

[ 215.600] Backtrace:
[ 215.600] 0: /usr/bin/Xorg (xorg_backtrace+0x36) [0x5

This makes me think that this bug is not intel related but instead related to xf86-input-synaptics and mouse. As I posted in launchpad, I do not get the x freeze when I have my cursor on the laptop screen and I unplug the hdmi cable to my tv.

In addition, researched backtrace:

Xorg really not crashes, it's goes to infinity loop(in my case) or something like this.
I setuped "Debugging with one machine Version 1" from "http://www.x.org/wiki/Development/Documentation/ServerDebugging" and after rebooting i see in debug files: xorg don't crashed.
Then i give xorg pid and run "sleep 60 && kill -n 11 xorg_pid", run minecraft and make it to freeze X.
Now i have real gdb backtrace.

Yeah, for me it's infinity loop:

while ((fabs(delta) >= fabs(incr)) && (bug == 0)) {
int nev_tmp;

if (delta > 0)
delta -= fabs(incr);
else if (delta < 0)
delta += fabs(incr);

when
delta = 548.33340590666785
incr = 6.3659874129151343e-314

with attached patch all goes OK, but im not sure it's correct, but solve problem.

alternative patch, and it looks better (but i cannot to test it now)

this silly mistake firstly appeared in http://cgit.freedesktop.org/xorg/xserver/commit/dix/getevents.c?id=3304bbff9b4ed63f1a47410a5320a136420ba2c6 commit.

Oh, now i see where are from this buggy code.

official patch in this theme https://bugs.freedesktop.org/show_bug.cgi?id=47281

alter.patch works for me! No more crashes.

fixed in upstream http://cgit.freedesktop.org/xorg/xserver/commit/dix/getevents.c?id=af88b43f9e604157b74270d609c08bdfa256a792

I took the official upstream patch and made a working PKGBUILD for https://aur.archlinux.org/packages.php?ID=38483

Seems to have taken care of the problem for me.

Bug was fixed in testing xorg-server-1.12.1.901-2

Fixed here also.
