Update as of 2011-11-30 Some package update appears to have revert/changed. The above notes an comments no longer seem valid for Ubuntu 10.04
Below is the new configuration setting we have had to use to make Ubuntu 10.04 work with serial; it is still not 100% as physical console access to the grub menu will not work. Here are the new settings: Ubuntu 10.04 appears to be working with this now: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=7 GRUB_HIDDEN_TIMEOUT_QUIET=false GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet" GRUB_CMDLINE_LINUX="console=tty1 console=ttyS0,115200n8" GRUB_TERMINAL="serial" GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1" *** Notice GRUB_TERMINAL_INPUT was changed back to just GRUB_TERMINAL="serial" - ENABLED, com1, vt100, 115200, redirect after console *****DISABLED***** -- yes / serial motherboard access -- yes / serial grub console access -- serial console shift key *does not* work to display menu -- serial console tapping ESC multiple times quickly will allow menu to be displayed -- no / no physical console displayable menu... BUT if you hit ESC it will appear on physical console ---- this is different than Ubuntu 8 and 11 which allows you to simultaneously control the grub menu from serial or console -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/537849 Title: fails to deal with a serial console correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/537849/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
