If I open a terminal after booting Xubuntu 11.10 and run the command dmesg I see this message at the bottom:
EXT4-fs (sda1): re-mounted. Opts: errors=remount-ro,commit=0
Do I need to worry about this message? I do not understand why the filesystem needs to be remounted. The partition sda1 contain the whole system.
If I uninstall the display manager this message disappear. If I change the display manager to GDM the message is show again, so it makes no difference what display manager is installed.
