I ran into this issue sporadically, but since yesterday I run into this issue every single time I try to login. In the past, rm -rf ~/.cache/compizconfig-1 helped.
Here's where compiz is sitting: Thread 4 (Thread 0x7f27565f3700 (LWP 1900)): #0 0x00007f27635749cd in read () at ../sysdeps/unix/syscall-template.S:84 #1 0x00007f2761deb740 in ??

Maybe re-building the .cache/compizconfig-1 directory changes timing enough to give dbus more time, and then it doesn't run into this situation? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to at-spi2-core in Ubuntu. https://bugs.launchpad.net/bugs/1285444 Title: Login Successful, Desktop Never Loads Status in at-spi2-core package in Ubuntu: Triaged Bug description: Here is what I encounter 1. Boot computer, boot proceeds normally 2. Reach standard Ubuntu login screen, nothing seems to be amiss 3. Enter user name and password 4. Login disappears, just see the pink "Ubuntu 14.04" background The desktop never loads, not even after ~30 minutes. The launcher never appears, and the Desktop background never changes to the user- configured background. Other features: * Cursor works fine, it can be moved around the screen * No error messages pop up * ALT+F1 etc. can be used to switch to different TTYs; all files on the system appear to be intact * Print screen button works (I will upload a screen shot when I get a chance to copy it onto a USB drive) * Hitting power button pops up a window prompting the user to decide whether to shut down * CTRL+ALT+DELETE prompts the user to log out * Desktop does not load on any user accounts, including the guest account To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/at-spi2-core/+bug/1285444/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
