General :: Disable Console Messages At Boot Time?

Sep 5, 2011

I am using Arch Linux and want to disable console messages which are displayed when the kernel boots. I have tried the quiet and loglevel=2 options in /boot/grub/menu.1st as given below:

kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/c6dbfcdc-fcd8-498e-9182-f3bddc4f05ff ro loglevel=2

However I am still seeing console messages at boot. I used grub-install after the changes.

Any ideas where I am going wrong?

General :: Control Console Session Keyboard Over Ssh?

Aug 13, 2011

I have a logitech wireless keyboard/mouse, but just lost the tiny usb wireless receiver.

I want to use my laptop as the keyboard for the other machine (Ubuntu 10.10) until I replace the keyboard and mouse.

Is it possible to control the console session's keyboard over ssh? I only want keyboard control, I don't want to use something like VNC because the video is too slow.

EDIT: I'd like to be clear that I want to be able to control gui applications running on the console session, so something like unix screen won't

General :: Difference In Settings: Console From Desktop & Ssh As Display Not Set When Ssh In?

Jul 2, 2010

Debian Squeeze: Linux jilldando 2.6.32-trunk-486 #1 Sun Jan 10 05:53:18 UTC 2010 i686 GNU/Linux

gdm for desktop manager

I have 4 differences situations, 2 work, 2 do not: So I think my server box (Jill) is messed up.

1) On the server desktop, I can open a console as the gui logged in user and type: xeyes and those eyes appear.echo $DISPLAY :0.0

2) If from that console I log in as another user (ros) and then type:
xeyes I get:

Error: Can't open display:
so that will be a problem.

3) If I ssh into my offices remote server from my XP machine with putty and x-forwarding and then type:
xeyes and those eyes appear.


4) If I ssh into Jill from my XP machine with putty and x-forwarding and then type:
xeyes I get:

Error: Can't open display: echo $DISPLAY (NOTHING)so that will be a problem.

This leads me to think I have something messed up on my Linux box Jill.

I have tried setting DISPLAY= to various values but same error, so this led me to believe something else needs setting. Especially as env yields alot more in situation 1 than in situation 2.

What can I set where, that will allow me run xeyes (anything X) in situations 2 and 4, just like in situation 1 and 3?

General :: Display The Source Machine During A Remote X Session In The Title Bar?

Aug 8, 2011

In the past, when I open a gvim session on a remote machine, the title bar of gvim would show the machine name in brackets. I am not sure if this was done by the remote gvim itself, or the local window manager. In the past I have used gnome2, although I am currently using unity (and finding it rather frustrating). Is there some setting I can change to always force remote windows to display the source machine?

General :: Ubuntu - Wmctrl Cannot Open Display When Session Initiated Via Ssh+screen

Sep 20, 2010

I'm using wmctrl on an Ubuntu machine to manage windows from a script, that I run inside a (gnu) screen.

If I start the screen session from the local machine, wmctrl works fine, including if I completely close the terminal window and issue the wmctrl commands when connecting to the screen remotely via ssh.
Conversely, if I connect remotely with ssh and start a screen, wmctrl doesn't work (returns "Cannot open display") even if I attach that screen session locally from the Ubuntu Terminal.

I guess there is some hidden screen parameter that doesn't get set in a way that allows accessing the display when it's launched remotely -- any ideas what it is and how to modify it from within a remote ssh-screen session so that that the script can access the windows?

Ubuntu :: Can't Send Log Messages To Console.

May 16, 2011

after upgrading to 11.04, natty, I have a problem with rsyslogd.

In previous releases I went to:


and uncommented the lines under comment:

# I like to have messages displayed on the console, but only on a virtual
# console I usually leave idle.

This was redirecting the log messages to a console I could get to via Ctrl-Alt-Fwhatever.

In natty, this no longer works. When I switch to the relevant console I get a blank screen with a blinking cursor.

The file /etc/rsyslog.d/50-default.conf still exists. A new arrival is also 50-default.conf.ucf-dist which, as far as I can tell is a clone and which I have also modified like 50-default.conf.

The file /etc/rsyslog.conf (configuration file for rsyslogd) exists and its last line reads:

$IncludeConfig /etc/rsyslog.d/*.conf

which presumably should force rsyslogd to read 50-default.conf at startup.

Looking at the running processes I can see that rsyslogd runs.

Red Hat :: Disabling Kernel Messages On Console?

is there any way to disable kernel messages on the console? The problem I have is that it is almost impossible to work on the console due to a flood of file system errors from the kernel.

I've checked /etc/syslog.conf and disabled kernel logging to the console. Even with syslog turned off the messages still flood the console.

Slackware :: No Console Messages During Boot?

Jun 23, 2010

I'm running slack64 13.0. At initial boot i see the two penguins and text from th kernel scrolls past until my root partition is mounted where upon all messages stop until the console prompt or KDM pops up. Everything seems to be operating as normal but i've no idea whats happening during the rc scripts (FS checking, etc). When shutting down though the rc.6/rc.0 script messages appear in the console though.

To my knowledge i've not changed anything that would effect this (just modified inittab for runlevel 4 & tty4,5,6 in runlevel 4).

There's nothing in dmesg but most messages don't get logged there as i understand.

Ubuntu :: Silence On Screen Console Messages At Bootup?

May 1, 2010

After grub loads the kernel I'll get an on screen message from the console showing: cannot reserve MMIO region And I was wondering is there a way to silence console messages so you don't see them at bootup?

Could setting dmesg work:-nlevel Set the level at which logging of messages is done to the console. For example, -n 1 prevents all messages, expect panic messages, from appearing on the console.So typing at a term 'dmesg -n 1' will work?

Fedora Servers :: RDP As Console Session?

I have RDP working fine on my machine, however when I am signed in locally to the machine, I get the "console" session, which is fine, but when I want to RDP from another machine, I am put into a separate session, instead of "taking over" the console session.Is there a way to do this, similar to how RDP works on a windows machine?I have tried running the mstsc /console command, but I still get stuck into a non-console session.

OpenSUSE Install :: Autologin - Syslog - Kernel Messages - Console

May 9, 2010

What i'm trying to accomplish seems rather silly but is needed for my little project here.

I'm using OpenSuSE 11.2 as a media center PC and need it to login automatically(console not X). That one i accomplished without problems.

However, after login i can see all the info about the services that were started and that needs to "go away".

One could do a "clear" in the .bash_rc and or .bash_profile but it will still show the login prompt which i don't want to see either (i don't even want to see the blinking cursor as well).

Question: How do i accomplish that so that the login console shows only the "splash screen" without any output of the kernel,rc.status nor the "issue-file"... just a plain blank screen ?

Slackware :: Error Messages On The Text Console When Runnig Startx

Jun 10, 2010

Slackware 12.0 (GNU/linux kernel 2.6) I am said slackware is very stable (I suppose this means it has few bugs). However, every time I run startx to start the graphical interface, for a brief moment I can see (just before the screen is put in graphical mode) a lot of error messages. How can this be? I use slack 12 a lot and have reinstalled this distro many times. However the described behavior always repeats.

Debian :: Console Only Session - Hard Drive Malfunction

Jun 16, 2009

My hard drive's file system has become totally mucked up. I had a few partitions on it, 0 is XP, 1 is vista, 2 is Debian, and 3 is the data. I know that it's this hard drive because when I disconnect it, any liveCD runs ok. After failing to boot puppy linux (liveCD), xp (bootmgr not found), debian (ended in kernal panic), I tried GPARTED. The xp and vista partitions are listed as existing, but they show a problem flag, gparted says they are corrupt, and they are not listed as having a start, end, or any data. However, the main data partition does list a start, end, size, and data space used.

I need to either format those or get into something that will let me access the data partition. Gparted either hangs on boot or doesn't recognise the mouse so I can't reformat the bad partitions. Are there any programs that will ignore the bad partitions and let me access the good ones? Any time I go into a linux distro it either ends up in kernel panic or the mouse doesn't respond. It's hard to explain. With GPARTED, sometimes it hangs at the third line, sometimes it fails at "mounting hard drives", and sometimes it makes it to the GUI but I can't use the mouse. Debian alternates between these as well.

If I keep trying it looks like I can boot, and it will recognise the partitions, but I can't use the mouse. I'm kind of familar with bash, is there a way to start up the terminal with no gui? If I could get a terminal up with a hotkey in the GUI or just start up from a terminal (no gui), I could type mv dev/sda3/ or whatnot. If I could get into a terminal of gparted I could format the bad parts of the drive to see if that would work. Otherwise it looks like I'm going to have to zero out the drive with the WD diag tool. The data isn't life or death, but it would save me some time.

Slackware :: Telinit 4 - Kdm - Open Console Session Prevents Shutdown - 64 13.37

Jun 4, 2011

I have a question regarding runlevels, shutdown procedure and KDM. I am on a freshly installed Slackware64 13.37 multilib system. The default runlevel in /etc/inittab is set to 3: multiuser w/o X.

Now, I log in as root and issue the command:


As expected, KDM starts up, and I log in to KDE (or another WM/DE) as a normal users. When I am finished, I either issues


In Konsole or click on Shutdown in the KDE menu. The shutdown process is initiated, as expected, but then it stops, and a window alerts me, that there is a session open by user 'root'. If I click OK, the machine is finally shut down.

Now, if I interpret this correctly, the behaviour of Slackware64 13.37 has changed here, compared to 13.1. In previous versions, the root seesion was closed, when I changed the runlevel to 4 with the telinit command. Now, the session remains open, obviously.

My question is: Is this the correct behaviour, and isn't this a security whole? An unnoticed (!) open root session while I am surfing the web as an unprivileged user in KDE could be dangerous, I think...

Is it misconfiguration in my system, or is this the way it should be?

OpenSUSE :: Evolution Does Not Display E-mail Messages?

Apr 10, 2011

I had a problem with my OpenSUSE with Tumbleweed repository enabled that required me to do a hard power off of my ASUS N61JV-X2 notebook PC. I had Evolution running at the time. When I did a cold boot of my laptop and I ran Evolution again, it does not display my e-mail messages anymore. In fact, I had to install Mozilla Thunderbird with the Enigmail extension so that I can read and write e-mail messages.

How do I fix Evolution so that it will retrieve and display my e-mail messages and I can write new ones using this software package?

Ubuntu :: Thunderbird Messages Don't Display Correctly

Aug 28, 2010

I am having problems with Thunderbird in Ubuntu Lucid. I am not sure since when. It could have been since I upgraded to Lucid from Karmic. When I open Thunderbird, a message pops up that is supposed to ask me for the password. However, it is all blank inside and doesn't display the text. I found that after I click on ALT+TAB a few times, the message displays correctly. This is very strange. Is anyone else having (or had) the same problem? Does anyone have an idea for a fix?I tried uninstalling and then reinstalling but it didn't work out (I didn't "purge" though).

Ubuntu Installation :: Kernel Messages And Display Becomes Corrupted

Feb 1, 2011

Recently I am trying to install the latest Ubuntu / Xubuntu but after the kernel messages the display becomes corrupted. The machine is a Clevo laptop with the dreaded SIS 671 / 672 chipset. The Ubuntu 8.04 is working flawlessly. Any other version I get several problems and depending on the mood of the system I get a vertical running display ( not readable ) or a left horizontal displaced screen (readable) ...

I tried more tan several CDs ranging from 9.01 to 10.10 both Ubuntu or Xubuntu. What is the plainest (simpler ) VGA mode in order to install it? I have tried vga=normal and even VGA =3 with no success. With the latest Ubuntu 10.10 I get another problem it simply does not recognize the HDD / SSD. I have traced the SSD problem with the sata_sis module in kernel 2.6.35 and up... Other distros have the same problem ...

Debian :: Console Display Mode Not Supported?

Feb 26, 2011

I've just tried to install X on my new debian system which had a nasty side effect.
I can see the bootcycle up to "Waiting for /dev to be fully populated." and then the screen switches into a display mode unsupported by my display. I've had problems like this many times before because the display returns it's capabable of resolutions like 2048x1536, which it just isnt. I've had to disable autodetection whenever using this display. One thing to note thought is that it's NOT X that's messing up the display. It's setting the wrong display mode even before the filesystems are mounted. And I've already uninstalled X with no change either. Also recovery(single user) mode has no proper display output either.

what is setting my display to the wrong mode?
