I now realise my comments were about a different kind of right-shifting
behaviour which affects only the text on a line by line basis, not the
whole screen, and which appears to be known as the staircase effect.
Sorry for posting off topic. But, since I started, I'll mention that I
managed to
I'm seeing much the same right shifting of the console while running a
serial console. System is Dell T110 PowerEdge, running Ubuntu 10.04
Lucid. Serial Console is running on windows with the same results using
either a mintty windows or a Cygwin X xterm window. It mostly seems to

In the case that I've examined I can add that the newline is supplied by
the log_success_msg function in /etc/lsb-base-logging.sh which is
sourced into the bash script providing the echo -n (Dell/SARA's
/etc/init.d/dataeng in this particular case).

(Multiseat) screen shifts when /dev/console
For all the users having problems with X keyboard input ending up on the
console (bastafidli, Jeremy, others): I finally appear to have solved it
for my system. Apparently, the newer evdev-code doesn't perform
exclusive grabbing of the device anymore! See this
I had this screen shifting problem on my multiseat system. I know very
little of the internal things inside Xorg an GDM, but I managed to
circumvent screen shifting with the following configuration in

I have not had any problem with input going to the console using no-
scroll. It is something to be aware of and test for, but it is a viable
option to make things work. no-scroll has nothing to do with where
input is sent. It's more likely that input showing up on the console
directly is

bastafidli, even though your screen is no longer scrolling, I suspect
your keystrokes are still being sent to both X.Org and a tty. This is
dangerous, because when you enter your login details in GDM, you could

Jeremy, it is surprising that your multiseat sessions start on ttys with
gettys. Convention has been to start X sessions on higher ttys where no

GDM. Specifying vt# on the X command line (i.e. /usr/bin/X :0 vt7 ...)

When I log off of one seat and X is restarting, the second seat picks up
both keyboards and mice. Once X has restarted the mouse and keyboard
goes back to the correct X session. Any Ideas? Not a huge issue as I
almost never log off but could be confusing since I plan on having the

1. Is your kernel 2.6.22 or newer? 2.6.23.15. I tried no-scroll but it didn't
work for me. After 25 or so lines were written to the console it started
shifting the screen.
2. Do you have a multiseat setup? Yes, two seats, using nvidia cards
with proprietary driver.
3. Does the screen
This bug is affecting me too on a multiseat setup. Every time the Enter
key is pressed, the first screen shifts. (I suspect this is because the
input is being sent to a tty as well as X.org, but it doesn't invalidate
the bug.)
I can confirm that adding no-scroll to the kernel parameters works
I am using Fedora 8 and I have the same problem. My screen shifts to
the right when a message is written to the console. When I run
xconsole, the problem goes away. xconsole consumes the messages so it
never makes it to the screen. Its not always possible to have xconsole
running, ie when your
@shawa: xconsole is a good idea. A few questions for you:
1. Is your kernel 2.6.22 or newer?
2. Do you have a multiseat setup?
3. Does the screen shift happen every time something is written to
/dev/console, or only occasionally?
4. Can you reproduce the screen shift on demand? If so, how?
I finally upgraded to Intrepid and took out the 'no-scroll' kernel
argument. Unfortunately, the problem still exists.

Bugs,
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the

appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.

nothing interesting in dmesg.

Note that the agpgart messages late in this dmesg output are not related
to the shift; I restarted X a few times because I had just upgraded to
Hardy and was playing around with my xorg.conf (stupid evdev changes).
The shift happened much later than 2725 seconds after boot.

My previous work around had one negative side affect... with console
output redirected to the serial port, unplugging my usb keyboard (which
generates several lines of console output) caused the machine to hang
hard. A new work around I found is to specify the kernel boot parameter
no-scroll.

Gutsy? Running 'echo -n a /dev/console' many times doesn't trigger

I'm running two nvidia 6200's (one pci, one agp). I'm on dapper, but
the root problem seems the same. If you run 'echo /dev/console' more

Sort of. The 2.6.22 release of the Linux kernel contains a fix that
eliminated most of the shifting that happened in 2.6.21 and earlier.
With 2.6.22, it is no longer possible to get the screen to shift by
typing echo -n a /dev/console many

I have been experiencing the same bug. After reading this bug report
and doing a little experimentation, I can confirm that output
(specifically scrolling) to /dev/console triggers the screen shifting to
occur. Furthermore, the problem only occurs when /dev/console
I had to go back to single seat mode. The system wasn't stable enough,
for other reasons actually. I had it working briefly yesterday and it
did happen, and this is indeed Gutsy.
