Public bug reported:
Binary package hint: plymouth
For a few weeks now, I get random startup failures like this:
- KMS starts up with large VT and some fsck/mountall spewage (normal)
- plymouth starts up, showing black screen with Ubuntu logo (normal)
- X starts up on top of plymouth, showing mouse cursor (normal)
- I get back to a VT with X mouse cursor on top of it; Moving the mouse
changes the cursor according to the underlying widget (like an input box from
keyring password question), but I don't see anything from the X session
- Ctrl+Alt+F1 gets me to a functional VT
- Ctrl+Alt+F7 switches back to X, now with full UI. However, as soon as I
press Enter in the input box of keyring, X freezes, and I can only powercycle.
This part was already described in bug 516412, but that got closed already.
I was playing around with improving boot speed, and removing
/etc/rc2.d/S50cups seems to make the Dell Mini 10 boot fast enough to
reproduce this bug with almost 100% reliability. It also happens on my
Dell Latitude D430 (utterly slow hard disk, boot time about 50 s, and on
the recent platform team sprint about half of the people had this
symptom as well.
As a first step I added an "fuser -v /dev/tty7" to the gdm upstart job,
which shows this in a case when booting _works_:
USER PID ACCESS COMMAND
/dev/tty7: root 321 F.... plymouthd
When booting fails (with this bug), I also get plymouthd (which is
presumably correct), but in addition a large number of error messages
like "/proc/NNN/fd/MMM: No such file or directory". I'll attach the file
in a bit.
