Ubuntu 7.10 not seeing LCD monitor correctly through KVM

Asked by WeberEInc

I successfully installed Ubuntu 7.10 on a server using a locally attached LCD flat-panel monitor and had no video errors at boot, launching gnome, or shutting down in this mode. Now, I've moved this server to a room with other servers and am running it through an iView KVM switch. Now, on boot and shutdown, the video display "MODE NOT SUPPORT" and will often have stray (often dangerous) looking striping across or down the monitor at random locations. I'm afraid I might be doing the monitor damage. And the bigger issue is, I would actually prefer to see the text-base boot and shutdown as opposed to the graphical display anyway.

Questions:
 1) Is there a way to tell Ubuntu 7.10 to 're-query the video' now that I'm on the KVM?
 2) Is there a way to tell Ubuntu 7.10 (or grub etc.) that I want to see the text of the start-up and shut-down.
 3) How does one check what 'mode' is being used at the different phases of booting/running Ubuntu... because once it is fully running, the video is just fine!

Thank you in advance!

Howdy Mike-d. here,
(disclaimer)
I usually just file bug reports and and sometimes I'm not very good at that either, but I do edit my grub menu a lot.

>2) Is there a way to tell Ubuntu 7.10 (or grub etc.) that I want to see the text of the start-up and shut-down.

Yes, edit Menu.lst with text editor(or double left click on the file, location: filesystem /boot/grub

Change "quiet" to "splash"

Example of Mine.

title Ubuntu hardy (development branch), kernel 2.6.24-8-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.24-8-generic root=UUID=46db9601-005d-430e-9b9e-3f29bf070d46 ro splash
initrd /boot/initrd.img-2.6.24-8-generic
splash

3) How does one check what 'mode' is being used at the different phases of booting/running Ubuntu... because once it is fully running, the video is just fine!

I'm not sure what mode you mean, or what you mean by mode, there is recovery-mode kernel under the regular kernel in the grub/ menu.lst

In a terminal window try:
root@AMD1Ghz-desktop:~# dmesg

Good Luck, ask for more info, if you need more info.

 I borrowed this from:

Hello xxxx....

Seems like a monitor error. Although it is a configuration problem with Ubuntu. You just need to reconfigure xserver using;

sudo dpkg-reconfigure xserver-xorg

and it should work thereafter.

Course to get to a terminal you press Control-Alt-F1 (or f2, etc.), Control-Alt-F7 to get back.

Login. (username and Password)

Run the command:

sudo dpkg-reconfigure xserver-xorg

then

sudo /etc/init.d/gdm restart

(or sudo /etc/init.d/kdm restart if using kde/kubuntu)

Of course during the dpkg-reconfigure you want to select the options that work best with your system. and I always configure the monitor using the 'medium' option, which will let you select the resolution and refresh rate in a method that makes sense to me. Easy might work better for others.

Hope this helps!
