Now that Ubuntu 12.04.1 is installed, there are a few things to check out:
- Grub boots into the old operating system and it still works.
- I had to change the default in menu.lst, but that was expected.
- Windows installation still works
- I have NTFS on /dev/sda1, but it’s not in the Grub configuration, nor the last configuration from March 2012. It was in a copy from January 2, 2012, so I put it back. It still works, but, dang, is it slow! No wonder I didn’t miss it.
- Suspend
- Works (see Fingerprint reader).
- Hibernate
- See separate post about hibernation.
- Shutting the lid suspends the laptop
- Works.
- Fingerprint reader
- Partially worked. I’ll post an investigation separately.
- Wireless networking
- No issues.
- Dropbox
- It seems fine, except the icon on the status bar is all white, like it’s an inverse shadow.
- Ctrl-Alt-Delete brings up log off dialog
- Ctrl-Alt-Delete doesn’t do anything. Fixing this required changing my keyboard shortcuts in the keyboard app.
Some other notes:
- The system was pretty sluggish and the hard drive was active. Running top showed tracker processes running. These are search indexers. I turned them off with Search and Indexing Preferences. I turned off everything on the Indexing tab. A restart was required. The system is quicker now, but swaps to disk more often. I checked memory usage between 12.04 and 10.04 and there was a significant difference:
In graphical mode, logged in via tty: 10.04=276MB 12.04=307MB
In graphical mode, logged in to X: 10.04=667MB 12.04=787MB
To try to deal with swapping, I installed zram-config. This seems to have helped. - Emacs was missing–I installed it with the Ubuntu Software Center along with an add-on to keep the Emacs cut buffer in sync with the system clipboard.
- Shutting down no longer has that minutes-long delay.
