I've made the relevant entries in /etc/crypttab and /etc/fstab match in both the 12.1 system and the 11.4 system.

I can now login to the 12.1 system, and the encrypted partition is now mounted under /home, BUT I have to guess when to type in the decryption password as the screen goes blank during the 12.1 boot sequence, between selecting it from the grub boot menu and the user login prompt appearing.

So, the question now is, how can I make the boot sequence (dmesg output) visible on the screen, so that I know when it is asking for the password?

Simply hit escape after making your selection from the boot menu. -- Ken Schneider SuSe since Version 5.2, June 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Sorry, Ken, I should have said that I'd already tried the escape route ;) and it hadn't worked.

Or for a permanent change edit /boot/grub/menu.lst and remove the splash=silent option or change it to splash=verbose and put it after the showopts parameter.

Unfortunately, this didn't work either, but thanks for the suggestion. When I say the screen goes black, it's actually still illuminated/backlit, but with a black colour, IYSWIM. It's similar to the appearance when the screen switches to power saving mode. After selecting the system to boot, I see the first few lines of the boot messages, then it goes black (as above), then I may see the green openSUSE screen with the wavy line, then back to black again.

I've just installed openSUSE 12.1 on my Dell Inspiron 1525 laptop, alongside an existing 11.4 installation. In other words, each system has its own / (root) partition, but they should both mount the same /home partition, which is encrypted. 12.1 is on /dev/sda3, 11.4 is on /dev/sda6, both formatted with ext4. [...]

For testing purposes I use a similar setup. However, I did not try to use my common encrypted home for both installations, yet. But I successfully updated several times this way from older versions. So, I fear I will have the same problems like you in the near future!

...

The 12.1 grub menu allows me to choose the 11.4 system to boot, but selecting this option takes me to the 11.4 grub menu first, from where I select the system I want to boot, eg 11.4 desktop, 11.4 failsafe or Windows, but it doesn't know about 12.1.

I think this is another story: grub is installed to the root partition and this partition is marked as active. The generic MBR code just boots the active partition, that is, sda3 with 12.1. The 12.1 installer detected your 11.4 installation and added a grub menu entry that simply boots from sda6 the same way the old MBR did when sda6 with 11.4 was marked as active. If you want to go back to 11.4 without having to go through the 12.1 grub, you have to mark sda6 active again. However, before doing that, please make sure that my assumptions hold true and you can recover to the current setup. That is, you remember which partition is active now and you know how to boot from a CD or USB and change back the active partition from there.

I strongly discourage you from using your home with 11.4 after you have used it with 12.1! Make an encrypted backup of your 11.4 home before you use it with 12.1 in case you want to go back.

Hi Bob; One way to eliminate the problems with a common /home is not to have them common but rather to have a separate partition that only stores common DATA, not configurations and the like. You could put folders like Documents, Music, Mail, etc. in a partition called say /common with symlinks from each separate /home to those folders. One of the most obvious problems with a common /home is that different distros (or even different versions of a distro) may well have different versions pf programs with differences in their configuration files. When run in different distros or versions the results may be unexpected or even catastrophic.
