I had restored a backup by deja dup, which was actually from a 13.10 32bit Xubuntu install on a different partition. I now have all my home directory from that installation. All seems well. The current bug report was initiated by apport immediately after reboot.
This machine is an i7 desktop.

(Cont) Trusty Tahr beta. 64 bit version. Updated earlier today then shutdown. Logon set to automatic without password.

During first login after upgrading Xubuntu from Saucy to Thrusty. 64-bit.

This is fixed in debian's packaging svn. If a release is not out soon, i will upload a patched version straight to ubuntu.

Running Xubuntu 14.04 64bit daily iso, dated 25 Feb 2014, fully updated, in Virtualbox-4.3.8.

Affects me during login, Running Xubuntu 14.04 fully updated, on Amd FX 6100 64-bit. (In real pc, no Virtualbox)

First use of XFCE session in Ubuntu 14.04 x64 kernel 12.x I chose the empty panel for first run.

This bug was fixed in the package xfdesktop4 - 4.11.3-2ubuntu1

xfdesktop4 (4.11.3-2ubuntu1) trusty; urgency=medium

  * Merge from debian. Remaining changes:
    - debian/patches/xubuntu_improve-nautilus-interactions.patch: added,
      should prevent nautilus from taking over the desktop if xfdesktop is
      running (and vice-versa).
    - debian/patches/xubuntu_set-accountsservice-user-bg.patch: update the
      user background property of Accountsservice on backdrop change.

I can see that this is marked as fixed in the beta-2 release of Xubuntu 14.04, but I am seeing something very similar with that:

Write the beta-2 ISO to a USB stick.
Boot up with it.
Select 'try Xubuntu'
Gets to the desktop, then crashes after a couple of seconds (monitor says no input, PC reboots after about 30 seconds)

This happens on two PCs, with both the i386 and x64 versions. One has an AMD A8-5500 CPU, the other a AMD A4-5300. Both have 16G RAM.

But exactly the same USB stick works, with the i386 version, on two laptops: one an Asus Eee900, the other an HP NC4200 (after using the forcepae argument when booting).

Interestingly, on at least one of the machines it fails on, the items on the boot menu are all duplicated - 123456123456-style - but the verify works and exactly the same USB stick looks normal on the two laptops.

Having tried again with the x64 version on both AMD PCs, selecting either 'Try Xubuntu' item in the menu boots to desktop, then crashes to reboot after a count of 'one-and-two-and.. ..and seven'

Ah, it's not xfdesktop - the same crash occurs if I try the beta2 lubuntu ISOs. Boot to desktop, then crash to, eventually, reboot (it just crashes after one second rather than several with them!)
