Comparison Between Ubuntu 10.04 and 11.04 ---------------------------------------------------------------
Ubuntu 11 exhibits the same behavior as Ubuntu 10. However... a potential workaround may have been found for Ubuntu 11 as it appears to be working... Enable motherboard redirection -- (ENABLED, com1, vt100, 115200, redirect after console *****DISABLED*****) appears to fix the issues Grub2 Config ------------------- GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=5 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=tty0 console=ttyS0,115200n8" GRUB_TERMINAL="serial console" GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1" Observed Effects in Ubuntu 11.04 ---------------------------------------------- - Disable motherboard console redirection (DISABLED, com1, vt100, 115200, redirect after console DISABLED) -- no motherboard serial access -- serial console shift key *does not* work to display menu -- serial console tapping ESC multiple times quickly will allow menu to be displayed - Enable motherboard redirection (ENABLED, com1, vt100, 115200, redirect after console ENABLED) -- yes / motherboard serial access -- error message(s) appears error: unknown command `terminal'. -- serial console shift key *does not* work -- serial console tapping ESC multiple times flickers the menu for one second then it disappears - ENABLED, com1, vt100, 115200, redirect after console *****DISABLED***** -- yes / motherboard serial access -- serial console shift key *does not* work to display menu -- serial console tapping ESC multiple times quickly will allow menu to be displayed I will be testing Ubuntu 10.04 again to see if the above solution works. For the record... Ubuntu 8 worked with - Enable motherboard redirection (ENABLED, com1, vt100, 115200, redirect after console ENABLED) settings -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
