Desktop system with 12.04 LTS 32-bit installed from USB, all updates applied. No other OS on system. Everything seems to work fine, but system will be used in a literacy center where anything unusual will cause students to be concerned. At Logout of any user, I very briefly get a black screen with white messages:
Could not write bytes: Broken pipe * Checking battery state...
At shutdown, I briefly get the preceding messages, plus:
acpid: exiting Checking for running unattended-upgrades: speech-dispatcher disabled: edit /etc/default/speech-dispatcher
I had to use a camera to capture these messages, as they are displayed for well under 1 second. There is no other symptom.
Following instructions in another post, I booted in GRU mode and repaired broken packages. It did not appear to me that anything was actually done and the symptoms did not change.
- Is something really wrong here?
- If not, how can I suppress the display of these messages so they don't trouble the students?
- Is there a log file somewhere that I could have found these messages in without using the camera?
I am new to UNIX, so I'll appreciate it if responses are detailed or include pointers to how-to information.
