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.

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.

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?

EDIT: not fully solved; there is (at time of writing) still an issue about bootlogd buffering until the logfile is accessible but that's probably as far as we are going to get for now, until someone peeks into the bootlogd source code.
Is it possible to review boot messages after boot? Kernel messages are available via dmesg (and many are logged early in the rc.M script by the /bin/dmesg -s 65536 > /var/log/dmesg) but many console boot messages are not kernel messages. During boot, messages can be viewed using Shift+PgUp but when the rc.S script finishes, init starts an agetty on tty1 which prints a login prompt. Then tty1 is no longer the console and Shift+PgUp cannot be used to scroll back through the boot messages. Any delayed boot messages do not have effective carriage returns so "marquee" across the screen, one following another, a line below.
Is it possible to leave tty1 as the console by de-configuring the tty1/agetty line in inittab, thus allowing Shift+PgUp to be used to scroll back through older messages and allowing proper horizontal alignment for delayed boot messages? I would try it but the inittab line x1:4:respawn:/etc/rc.d/rc.4 runs /usr/X11R6/bin/xdm and this grabs the first unused tty<n>. The xdm man page and xdm config file comments do not reveal whether it is possible to make xdm use a specific tty<n>.
Another solution may be something like the sysvinit binary that intercepts all console writes and then dumps them to log at the end of the boot process but if it were that easy or useful it would already be done and publicised (wouldn't it?).

after upgrading to 11.04, natty, I have a problem with rsyslogd.
In previous releases I went to:
/etc/rsyslog.d/50-default.conf
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.

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.

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?

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 ?

When sending an LQ post, my browser says "You're about to send information that's not encrypted". OK. I tell him not to show the warning again. But what if I want to encrypt? How do I do it?

I am searching for a way to broadcast a simple message from a server to the other machines (clients) on my local network every day at 22:30 (10:30pm) to warn users that the server will shutdown in 30 minutes (energy saving strategy). Basically, I was thinking to add a cron entry ion the server crontab to do so. before I go ahead with that, I tried several ways to accomplish this action. Then I tried simply "wall" and got a text promt to type in my message. At the end I pressed CTRL+D and got a popup displaying my message. So it worked but it was on the server's monitor. How can I send this message to a remote machine? Is wall the proper command to do so?
I also tried using paswordless ssh..It doesnt work. Basically I can login on the remote machine using passwordless ssh but when I issue either kdialog or xmessage, I get error "cannot connect to X server on diaplay 0:0" (or something similar).I tried also ssh 'wall 'message'' but it also says "cannot connect to X server on diaplay 0:0"So far I have several ways but nothing really works..There must be a real way to to that?All machines are Slackware 13.1 based.

I have around 6 email accounts for business & private use that I retrieve and send via pop/smtp with Kmail (Version 1.11.4). But it seems that all my outgoing mail is only sent via one account (say first@gmail.com) even if I select another account for the outgoing I.D field and FROM field. When I look in the sent folder the headers shows the correct sent from account but my recipients headers show they were all sent from first@gmail.com! Ebay keeps bouncing my emails back too as a result saying the email is not registered. It used to work just fine so not sure what is happening. I have tried reinstalling Kmail/kdepim-4.2.4-x86_64-1.txz deleted all the accounts and recreated them but the problem persists.

I'm having, oddly enough, stability problems on my main slackware desktop. Whenever I try to do certain things, for instance going fullscreen on a flash video, starting regnum online or open arena, it drops out of X into the command line with a few error messages (next time it crashes I'll post the messages). On occasion, it'll do that without any input. Now, there's a few major changes I've had on the desktop since yesterday, chiefly that I've been able to connect it to the net for the first time in a few months. Now because of this, I've been installing plenty of software from slackbuilds, plus flash from adobe (necessary evil). I'm using xfce with some compositing on a geforce Ti 4200 AGP 8x 64Mb with nvidia drivers installed and dual monitors, each now set to 1280x1024 and in twinview, pentium 4 2.8Ghz, 1 GB ram. HDD has a 70GB ext3 slack partition, triple booting with 80GB ext4 ubuntu lucid partition and 40GB ext4 mint isadora.

I've always been under the impression that when using the console only a notebook's display is used. Apparently this is not the case as I just booted off of a SystemRescueCD and the display on the notebook was mirrored on my external HDMI connected monitor. I have a feeling this is set somewhere in the kernel, but where?

This is a new (Less than one month) old netbook that is just running Slackware 13.1 with KDE.Now, every 10 or so minutes I'm getting a "Battery disconnected/Not found" error and it's insisting I plug in.Now, the battery itself is fine since by ignoring these messages, I'm getting 5-6 hours battery life easily but none the less. It's a concern.It appears to be software related rather than a bad battery.Has anyone experienced this and/or know of a solution?

I use various hard disks in my computer. When I install a 13.1 disk, the six text consoles <Ctrl-F1> through <Ctrl-F6> are shifted to the left such that the first 2 characters in the line are off my flat panel screen. I use several different disks on this machine and all other disks are properly aligned. change the vga line in /etc/lilo.conf to vga = normal rather than vga = 773. This didn't fix the problem and resulted in another problem. If I adjust my flat panel horizontal adjustment, when I start XWindows, those screens are too far to the right. Is there a way to adjust the horizontal offset only for the consoles?

I just installed Slackware 13.1 on my Acer a0531h. My first problem is the size of letters on pure console. It's too small. I tried tweaking lilo but even using 'normal' doesn't change the size of letters. I haven't changed the default font (I think it's called default8x16). The text looks pretty sharp though, so I'm wondering whether this is its native resolution. The text during installation was huge, and quite blurry. I just want to have a text size I can easily read and if possible be sharp. I know I can start X and have whatever font family and size I want, but somehow I feel better using pure console. Just in case it matters, I want to say that eventually I want to have UTF8 support on the command line (so that I can read and write Greek).

I'd like to be able to manually mount a USB stick in console (before X is started) and I can't seem to find a good way to do that. I'm not too smart about HAL and UDEV and I don't want to undo the auto mount feature when X is running but still be able to manually mount and unmount as necessary; like for installing patches and packages after an install or version upgrade. It seems like there should be an entry in /etc/fstab and a directory in /mnt or /media but danged if I can find something that points the way.

I have sometimes wished to place a reminder, to be displayed after I login. And what I did was to write it in /etc/motd or in /etc/issue. But something in the system erases or writes a new motd/issue.What would be the easiest way to have a reminder printed on the console just after login?

I need to be able to install new virtual machines with Oracle VM. There's console button in the web interface which opens VNC connection to specified Virtual guest but it haven't been able to get it to work yet. [URL] I converted the rpm to tgz package and installed it. It installs the packages to /opt. I also tried info in the following link: [URL] Firefox's about:config lists the ovm-console plugin active and when I press the console button in the web page it opens up a new window. The window doesn't prompt for missing plugin but it won't open the VNC display either. As an alternative I installed tigervnc from Aliens repo but it has problems with the mouse cursor. My laptop mouse cursor goes at different pace than the vnc client cursor so it makes its use very hard.
Edit, forgot to mention that I checked and tightvnc-java package is installed on the Oracle VM manager and the console button works on Windows and on Fedora when I tried it. So the issue seems to be limited to my Slackware64 setup.
