I'm dual-booting Windows 10 and Kubuntu 16.10 and I had the issue with the grub2 config file having a 10 second timeout then defaulting to 30 seconds upon boot.
I tried the workaround in post #8 which then caused my boot menu to be completely hidden. I then removed both files described in the workaround and removed the GRUB_HIDDEN_TIMEOUT value and ran sudo update-grub which seemed to have fixed my problem. I have also had hibernation enabled for some time as noted in the GRUB_CMDLINE_LINUX_DEFAULT "resume=UUID=xxxxx" (swap partition) argument. I find hibernation extremely useful with laptops (I've removed the UUID for security reasons) # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT= GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=xxxxx" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273764 Title: Grub ignores TIMEOUT options on /etc/default/grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1273764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
