X crash on start (Xubuntu)

[intherye]

Binary package hint: gdm

I installed Xubuntu 9.10 beta from the Xubuntu beta installation disc.

In the beginning everything was working fine. But after some time (maybe after changing resolution via "Settings -> Display") I have difficulties logging into X. This takes between 1 or 5 login tries.

Along with that problem I lost the xfce-panel, which I worked around with adding it add manually to "Session and Autostart".

My system is quite "default" and uptodate, with some packages from medibuntu.

In my home directory there's a .xsession-errors.old with these contents:

/etc/gdm/Xsession: Beginning session setup...

on success, .xsession-errors looks like that:

[Sebastien Bacher (seb128)]

seems rather an xorg issue than a gdm one

[Bryce Harrington (bryce)]

Hi goatsly,

Thanks for including the attached files. Could you also include your /var/log/Xorg.0.log (or Xorg.0.log.old) from after reproducing the issue?

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[intherye (intherye)]

You're right, there's a backtrace at the end of the Xorg.0.log.old. (attached)

The procedure when the xserver is failing is that (after entering the password):
1. the xubuntu "glowfly" screen
2. blanking
3. the glowfly screen
4. white screen
5. login screen again

on success it's:
1. glowfly screen
2. blanking
3. changed resolution glowfly screen
4. white screen
5. xfce desktop

[Bryce Harrington (bryce)]

Please collect a full backtrace - see http://wiki.ubuntu.com/X/Backtracing for guidance.

[intherye (intherye)]

I just saw that there's a "??" when calling nv_drv.so in the backtrace. But there's no *-dbg package for xserver-xorg-video-nv. If it's of any relevance, could you please point me to some information how to get debug symbols for this driver?

[PokeParadox (pokeparadox)]

I'm also having this problem with the release version of Xubuntu 9.10. I must say that I upgraded from 9.04

[seron (mirimiri66)]

I have this problem if I select any other resolution than 800x600. I have Xubuntu 9.10 as a fresh install in VMware Fusion 3 (it was the same in 2).

[_Nick_ (xtreme1-nick)]

I'm having a similar issue after upgrading to Xubuntu 9.10. My monitor is a Dell that permits multiple inputs. In this particular case the machine is off one of the DVI inputs. I had to switch from one input to another and when switching back I had no screen.

I've attached my Xorg.O.log file. Please let me know if you need anything else. This is the first time this has happened.

I run into same issue. I was never able to log in through GUI. Log in through text console was fine.

I had to delete all content from ~/.cache/sessions to be able to log through GUI again

[intherye (intherye)]

Since in the backtrace there was something about cursor, I tried editing xorg.conf and changed the following in "Device" Section:

Option "SWcursor" "true"
Option "HWcursor" "false"

Now login always works on the first attempt.

[_Nick_ (xtreme1-nick)]

Hmm, I've never had any issues with logging in. All my problems seem to stem from not using the machine for long periods of time ( >24 hours).

I came in this morning to find the machines display to be non responsive, I was able to SSH in an attempted to restart gdm (didn't work), my .xsession-errors file came back with:

[Timo Aaltonen (tjaalton)]

Are you all using nvidia chips? Does disabling HWcursor help for all?

[Mattias Holmlund (u219)]

I have the same problem as the original submitter. I am running Mythbuntu 9.10 (with xfce4) and have gdm setup to login automatically. Unfortunately, the login fails with the "Fatal IO error 104 (Connection reset by peer) on X server" messages in .xsession-errors. If I then retry the login a few times, the login will eventually succeed and everything seems to be working as it should. After a successful login, there are no Fatal IO error messages in .xsession-errors.

After an unsuccessful attempt, I also found the following in Xorg.0.log:

(II) intel(0): EDID for output TV1
(II) intel(0): Allocate new frame buffer 1024x768 stride 1024

I have attached the complete Xorg.0.log.

This is on a Mac Mini with intel graphics, which means that the problem is not specific to nvidia.

Please let me know if you need any more info.

[An_tony (clear-ref)]

I experienced the same problem:

Fatal IO error 104 (Connection reset by peer) on X server

intermittently on Ubuntu 9.10 32-bit running as a guest machine on VMware 7.0.1, w/tools 8.1.4 build-227600. Adding:

Section "Device"
        Option "HWcursor" "false"
        Option "SWcursor" "true"
        Driver "vmware"
        . . .
EndSection
,
to /etc/X11/xorg.conf corrected the problem. I generated the base xorg.conf with Xorg -configure.

The problem, in this case anyway, isn't specific to Nvidia cards.

[Ian Gough (igough57)]

Same problem. Xorg SEGV upon xfce login from GDM after upgrade from 9.04 to 9.10.

Setting SWcursor to true as indicated in earlier posts prevents the crash. Xorg.log and backtrace attached.

Hi Goatsly,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

Please note we also provide technical support for older versions of
Ubuntu, but not in the bug tracker. Instead, to raise the issue through
normal support channels, please see:

    http://www.ubuntu.com/support

If you are the original reporter and can still reproduce the issue on
Lucid, please run the following command to refresh the report:

  apport-collect 460478

If you are not the original reporter, please file a new bug report, so
we can work with you as the original reporter instead (you can reference
bug 460478 in your report if you think it may be related):

  ubuntu-bug xorg

If by chance you can no longer reproduce the issue on Lucid or if you
feel it is no longer relevant, please mark the bug report 'Fix Released'
or 'Invalid' as appropriate, at the following URL:

  https://bugs.launchpad.net/ubuntu/+bug/460478

[intherye (intherye)]

I tested this bug on Lucid again:

I changed /etc/X11/xorg.conf entries back to

        Option "SWcursor" "false" # [<bool>]
        Option "HWcursor" "true" # [<bool>]

again. The bug doesn't occur anymore. Login worked always at the first attempt since then.

--> Fix released.
