while installation clearos 7 as gateway mode, reboot and console goes blank.
need to perform the following steps to get the console back.

please advice if this is a bug or something that i will need to perform every update?

1. boot grub -> type: e to edit -> search for line: linuxuefi -> append string to end of line: "nomodeset" -> cltr-x
2. boot sucessfully
3. edit /etc/default/grub
# vi /etc/default/grub
:
replace line: GRUB_CMDLINE_LINUX="rd.lvm.lv=clearos/root rd.lvm.lv=clearos/swap rhgb quiet"
replace with: GRUB_CMDLINE_LINUX="rd.lvm.lv=clearos/root rd.lvm.lv=clearos/swap rhgb quiet nomodeset"
:
4. execute command to update grub
# grub2-mkconfig -o $(readlink -f /etc/grub2-efi.cfg)
5. reboot machine n finally get my console back.

regards,
kuenn

    I am not sure of your grub2-mkconfig command. I'd have used "grub2-mkconfig -o /boot/grub2/grub.cfg" but I did get some weird errors when doing it and had to write the file elsewhere and then copy it into place. I think that was just my system. You should be able to look at /boot/grub2/grub.cfg and check that your changes have been made to the "linux16" line or the equivalent efi line (linux16efi?) if you have en EFI system. If your changes have been written, then they should be permanent.
