[SOLVED]Xorg segfault when moving pointer to third monitor.

d_d · 2009-11-18 11:52:02

EDIT: Temporarily resolved by downgrading to xorg-server 1.6

The setup is as follows:

GPU0(NVIDIA 8800GTS)
=> Monitor0
=> Monitor1

GPU2(NVIDIA 8800GTS)
=> Monitor2

Everything used to work with a Xinerama setup (I know xrandr is what I should be using), but after a recent yaourt -Syu I now get segfaults when moving my pointer to monitor 2 (the leftmost monitor) The pointer also jitters back and forth between monitor 2 and 0 (the middle one).

Everything else works fine. (for example, moving a window to the leftmost monitor using the keyboard)

Here is the Xorg log:

I've also tried to replace the xorg.conf with the 'X -configure' file and use xrandr, but only one monitor is detected.

I'm completely puzzled. Any help is appreciated.

Segfaults are nearly always upstream bugs, to be reported upstream

d_d · 2009-11-18 12:09:08

Ranguvar, You're most likely right.

I found this: http://bbs.archlinux.org/viewtopic.php?id=83686 which sounds similar.

d_d · 2009-11-18 12:26:52

Update: changing to nvidia-173xx makes no difference

d_d · 2009-11-18 13:52:22

Interestingly, if i comment out the xinerama option, it works fine, and my pointer can travel to the leftmost screen without problems. :-S openbox is only on the centre screen though, so I get the X pointer on the blank screens), in this case, Xrandr showsonly one output though.

downgrading xorg-server to version 1.6 solves the issue.

llcawthorne · 2009-11-18 15:30:07

Yeah, sorry I didn't notice this post sooner, or I could have saved you some trouble shooting.

After testing and discussion on NVIDIA forums with someone else having the same problem, we realized that it is apparently a problem with any Xorg 1.7 release using Xinerama with a monitor positioned Left of another display.

The person I was talking to said he bugged it, and rearranged his monitors right of. I downgraded to xorg 1.6 and haven't given it too much though since. I should probably follow up on that and submit a bug to xorg or something... or you are welcome to!

Works great with Xinerama turned off, which is actually a fine option for me since I don't tend to move windows between displays, except I am using Xinerama to work around an xmonad bug in handling multiple non-Xinerama displays. I would have never caught it if I hadn't tried turning Xin on to fix the xmonad issue right before the 1.7 upgrade and gotten curious why my setup started going crazy (since I have a monitor with two monitors to the left of it)..

One thing that also works is making your left most monitor screen 0 and setting the other two monitors to be RightOf it, or at least that worked for me. Unfortunately, my left most monitor is a 46 inch tv that is often turned off or on a different input, so I can't really have it being screen 0.

Medium Priority bug 24986:

d_d · 2009-11-18 15:41:11

Thanks! The leftof/righof isnt too much of a problem for me, so i'll do that.

Clearly, My google-fu failed me on this.

Ranguvar · 2009-11-18 21:48:52

Please comment on that bug though, so the developers know more people are affected!

SiB · 2009-11-18 22:58:21

I filed this bug some days ago: http://bugs.archlinux.org/task/16999

It don't know how to fix that problem. There is not indication of leftof/rightof in my xorg.conf.

EDIT:
It seems that this format :

-> Screen 0 "Screen0" 1280 0
-> Screen 1 "Screen1" 0 0
Screen 2 "Screen2" 3200 0

is also prone to this bug. I guess we need to wait for a upstream fix.

Yeah, you don't have to specifically use LeftOf/RightOf. If you hardcode the numbers and still have one that is arranged left of another, it still breaks (I tried hardcoding locs into my xorg.conf to bypass the problem to no avail).

The problem is your Screen 0 starts at 1280, and your screen 1 starts at 0 (left of screen 0). This would probably work (but not match how your monitors are physically arranged:

->   Screen      0  "Screen0" 0 0
->   Screen      1  "Screen1" 1920 0
    Screen      2  "Screen2" 3200 0

llcawthorne · 2009-11-19 00:59:26

Thanks for the advice Ranguvar. I went ahead and did so, since I had information to add and wanted to be CC'd anyway. I am not accustomed to working with big bug trackers and such and wasn't quite sure what passed for polite and useful in a comment on something like that.
