Re: Problem with no display on 10.04 beta2 server
I've noticed when removing quiet, but leaving splash, you get double kernel messages. The first set are normal text output and then again when plymouth takes over and re-displays them, but this time a lot slower. Anyone else run across this? The LVM bug is interesting, as our default preseed creates 5 LVM volumes for the rootfs. Could explain why a lot of my installs and boots are failing.

For beta2 the situation is that splash is disabled by default, the console messages show up on VT7 during boot, then at the end of the boot the screen switches back to VT1 to show a login prompt. That has been my experience with all the systems I tested the beta2 ISO with. So you should get a login prompt in the end... and you should also be able to display the boot messages by using Alt-F7. What /can/ happen is that the system boots so fast you don't have time to see VT7 before it switches back to the login prompt on VT1. What /can/ also happen is that you installed Lucid from a previous beta (one with "splash") and upgraded, so you still have that kernel boot option. However in both cases you should get a login prompt...

So how > would removing them to see the boot process cause the filesystem mounts to > fail?? Yes, it is starting to mount filesystems, but something could go wrong. Some examples: Lucid beta will not succeed if you have more than 4 lvm filesystem defined in /etc/fstab. [https://bugs.launchpad.net/bugs/557909] (Also, if you have defined mount points for snapshots, the upgrade to lucid will have converted them to UUID's. Bad idea, because snapshots have the same UUID as the filesystem where they are a snapshot from, so they could get mounted in the wrong place. This will not halt boot, but could cause confusion.) Or, you could have defined dhcp in /etc/network/interfaces, which will cause resolv.conf to stay empty. If you mount network shares by hostname, this will halt your boot process. [https://bugs.launchpad.net/bugs/558384] With splash, plymouth will ask what to do. (for example, skip mounting that filesystem, or go into recovery shell,..) So, if anything happens, you will just sit there if you have no splash, but you will see the error messages better. -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

But if it gets as far as mounting the file systems, surely it's well into the boot process at that stage...unless you have 4 LVM volumes for the root file system (??). Not 100% sure I'm following you - booting with the "quiet splash" you see nothing, and other than that, boots fine.

In the past, it might have, but I tried this on a desktop edition of Lucid beta and it was a bad idea. Boot halted (because of the bug where you can't mount more than 4 lvm volumes.) Without splash and quiet, you can see the messages, but not the buttons you have to press to skip mounting the volume. -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

RE: Problem with no display on 10.04 beta2 server
As discussed before on this list. PLEASE GIVE THE SERVER DISTRO ITS OLDFASIONED BOOT WITH ALL THOSE MESSAGES. WE SYSOPS MIGHT NEED IT ONE DAY. Or at least a way to configure it this way...

Problem with no display on 10.04 beta2 server
Hi! I have an IBM 3550 server where I have installed the 10.04 beta2 server on. On reboot after the BIOS messages all I get is a blinking cursor and then it disappears. If I try ALT+F1/F2, ENTER and so nothing happens no login prompt nothing! Connecting through ssh works but I fear the day when I need to troubleshoot the server at the console... -J - Janåke Rönnblom mobile: +46-70-3970743 web: http://www.ronnblom.se - "Those who do not understand Unix are condemned to reinvent it poorly." -- Henry Spencer -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
