I have installed KDE and all the software for it to run on my server through the serial console but when I go and run "startx" I get the following and KDE doesn't start running.

Is there a way to get console output over a serial (COM) port? I have a box that I use as a NAS, DNS, DHCP and mt-daapd server, I don't have a spare monitor and it is not worth buying one just to use it once or twice a year.
I found this guide [url] but it doesn't work with Natty
I am trying to connect to serial console, local one, just to verify than it works, is is possible?Well, I configure serial console
Code:
# ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

It is started, now I am trying to connect to the console via minicom, is it possible from machine where the console is running?If not, how could I check it remotely?

I've got a home server running ubuntu 10.0.4. It have no monitor or keyboard. So I want to access it from a serial console. (I use SSH currently but if something goes wrong, I need to be able to do something... so serial console seems a fine thing). OK, so on the server, I tell grub to output everything on ttyS0 and opened a getty on ttyS0. On the client side (Laptop running Ubuntu 10.0.4 with pl2303 USB to Serial adapter) I use Minicom.
Home server restart:I see grub menu, linux kernel messages, login prompt. But, I can't do anything:In grub or at the login prompt, no key press is recognized by the server.I've got write permission to /dev/ttyUSB0. I tried a different getty (mgetty)with no success.I stopped the getty on ttyS0 on the server. And run minicom.
From the server's minicom, if I type something, it appear on the client screen. From the client's minicom, if I type something, some garbage appear on the server screen :(One of this things for each char typed). If I short-circuit pin 2 and 3 of the client serial port, it echoed what I type. The two serial ports are connected with a nullmodem cable. (seems to be a full handshaking cable). Of course, same serial port config for both minicom, grub and getty. Hope I'm understandable enough. (English not my primary language). Can somebody help me make this *$*#! serial console working right ? I'm on it for 10 hours now with no success...
Edit : I nearly forgot to tell you I had to update the standard ubuntu kernel to 2.6.34-020634rc1-generic because there was a bug in the pl2303 driver in the stock kernel (2.6.32-25-generic) which prevented me from doing anything (even receiving).
I have a dell poweredge server. In the bios, it has the option to redirect the screen to the serial port. There is also the check box "redirection after boot" which from what I understand will let me to continue to use the serial port attached to a terminal as if it was the main VGA monitor with a keyboard attached.
When I start the machine up, everything goes as expected, I see the output from the bios on my serial terminal, until debian actually starts booting. It all goes blank. If i attach a monitor i can see it is indeed booted and waiting at the debian login prompt. What should I do from here? I was under the impression that if i enabled "console redirection after boot" that the os would be none the wiser and i could continue using the serial console as the main screen as needed, but that does not seem to be the case.
i was using a serial console program (not minicom) two weeks back but took a break and have no idea what it is! man, it was awesome, too. it had a nice gui, similar to hyperterminal...and from what i think i remember it came packaged with f14.

I am looking for a solution to administer my remote server running SUSE LINUX 10.1 (X86-64) - Kernel 2.6.16.13-4-smp. I have made changes to server and is able to see the boot process and also able to login to system through serial console.
My question, will I be able to administer the server through serial console incase if my root partition is corrupted and system has gone to maintenance shell(or root shell).
Also is there way to go directly to maintenance shell from grub(not talking about single user mode). I want to go maintenance shell where / partition is not mounted.
I am trying to connect to a cisco console port using the usb to serial converter. I am using minicom and I changed me setting to reflect the USB converter cable, but it isn't working. I have set my baud rate to 9600, 8 data bits and no parity. Minicom acts as if it is connected (it doesn't give any errors), but there is nothing on the screen and nothing happens when I type. Also, I use the tail command and it sees the usb connector connected when I unplug it and plug it back in.

The module (and a few others) appear to be loading for my Audigy2 card. Sound is fine in KDE and all relevant applications. I have no sound outside of X. I've made certain that the volume is up on ALL outputs in "alsamixer" there's got to be something I'm missing. I've just checked....I connected one of the line outs from the sound card to an amplifier and used madplay to play a song in console. It worked fine. The problem seems to be that the sound is not being routed to the video card (via spdif) in console mode. This does work after I've started X as I have sound on all applications when running KDE.
I am new to linux terminal programming and all but i want to set up a simple serial communication from my desktop through USB port. The actual idea to to write some data in the terminal and build a terminal program that sends the data to the usb port with a fixed baud rate. are there ready made terminal programs available for this simple communication?or atleast any Graphical tools which could help me build and design such a terminal in ubuntu 9.04?

View 7 Replies View RelatedI have mounted an NFS share with ISO images on my kvm Server. If i connect such a iso to a VM (using virt-manager) for installing a operating system i get the following error on startup: Error starting domain: internal error Process exited while reading console log output: char device redirected to /dev/pts/1 qemu: could not open disk image /mnt/iso/public/Linux/Distributions/Debian/debian-504-amd64-netinst.iso: Permission denied
The problem is definitly that kvm (or qemu or libvirt-bin, i don't know) tries to set permissions (rwx owner for libvirt-qemu, --- for kvm group, --- for other) on the file, although it has read permissions. Is it possible to change this behavior?

View 1 Replies View RelatedI have a bit of a dilemma. I'm attempting to use a microcontroller to send MIDI messages over a virtual serial port. I want to (eventually) read them with Mixxx. I'm using an FTDI chip, so I get a /dev/ttyUSB0. I've tried spikenzielabs' Serial-Midi program, but it doesn't see any serial ports. NOTEMIDI looks really old and won't compile on my 10.04 LTS machine.

I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5).I have /sbin/agetty -L 9600 ttyS0
in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control.I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but
cat < /dev/ttyS0. just prints out weird characters from what I type.
On my CentOS 5.2 install I've installed a dual-port serial card based on the NetMOS 9835 chipset. I've followed the serial instructions, but everything they tell me to do is already done - see setserial outputs below. I've compared these values to the lspci output (below, NetMos card is at the bottom of the output) for the card and it appears right. Problem being, I can't use the serial ports. Oh and I did use search, and looked at every 9835-related article before posting this :)

I am hoping to be able to get an old serial-touchscreen to work with a usb/serial adapter. I had this touchscreen working some years ago on different hardware. I would like to hook it to the machine I am setting up as a multimedia host with mythtv among other things.
Following the instructions I left behind when I got this to work way back when does not work. See [URL] ....
This info is a work around to get the xserver to see the touchscreen. [URL] ....
I do know that the touchscreen works as I am able to get garbage on the screen as in the first part of my howto. But I have not had any success getting xorg to see it. I wish I had posted a copy of the xorg.conf at the time, but......
There is an issue with the current xserver in testing that I am hoping the next update (in unstable) will fix when it gets pushed to testing. That is that Code: Select all# X -configure fails with a segfault. So I am not able to generate the xorg.conf needed to get it to work. I was going to post a bugreport, that is when I found out there is an update in unstable, so I am waiting for it to get pushed at the moment.
Anyway I am hoping that I can link /dev/ttyUSB0 to /dev/tty0 and get it to work. I would like some kind of guess as to my chances of success before I go to all the work of getting the monitor hooked to the host.
I'm logged into my Ubuntu 11.04 box using SSH, and I need to start a program - but it is a Windows GUI program which runs under WINE.
How can I start the program from the SSH terminal so that it opens on the desktop, and then stays open even after I log out of SSH.
I have installed Debian 5.0.4 on a 600Mhz iMac G3. When booting the usual text scrolls down the screen and then the screen goes blank. Cont-Opt-F1 gives me a terminal window. X is apparently configured and running since 'startx' returns the usual something about -1 error message. I am newly returned to the terminal window after years of GUI slackitude and I am not able to get either GNOME or KDE to come up. Is there some file I should be editing (sudo nano /fixthisthing) I feel like I am swimming in the right ocean, I just haven't spotted the island yet. The learning curve on Linux is pretty steep but I have managed to make the password deal quit making me change passwords at every, single, solitary, login, so I am not a total feeb. Some hints on navigating the file system wouldn't hurt either.

View 3 Replies View RelatedI'm having an issue with Ubuntu 10.04 server, where it is not bringing up a console on the local machine.
The only display on the local screen (and in /var/log/boot.log) is:
Code:
fsck from util-linux-ng 2.17.2
/dev/sda1: clean, 100725/2342912 files, 781590/9357824 blocks
init: ureadahead-other main process (595) terminated with status 4
Hitting <alt>-<f[anything]> just brings up a blank screen with a single flashing cursor, and no login prompt.
The ureadahead message sounds like the classic Windows error: "The operation could not be completed because of the following error: The operation completed successfully." So ureadahead isn't the problem.
Also... ssh works, but other services (apache, mysql, smbd, nfs-kernel-server, etc) need to be started manually.
