[SOLVED] output VC/tty = xterminal ? (cat /dev/?? or something?)
Hi!
I'm trying to access the output shown in vc / tty in X. Just "cat /dev/tty1" in an xterminal seems to be way off track, so is "cat /dev/vt/1"... any hint on how to do it right?
Thx!

- /dev/tty# are all readable (but not working)
- /dev/vc/# have the right permissions - can access all the user is logged into, none else (still, wrong folder, but that "right permissions"-thing did catch me).
In this scheme
- /dev/tty# are symlinks to /dev/vc/#, and always shows as "lrwxrwxrwx", don't care.
But tty devices not are for the "capture" purpose
a better "cat" is to use "fold" or better setterm
fold -w80 /dev/vcs12 (current scheme)
fold -w80 /dev/vcc/12 (devfs scheme [Arch Linux])
setterm -dump 12 -file /proc/self/fd/1
PS: Because a bug, there no anymore vcs1 and vcsa1 in 2.6.30. http://lkml.org/lkml/2009/7/10/369

[solved] duplicate post TTY terminal on DVI output
Hi
Does someone know how to turn video output on tty over HDMI?
Last edited by infoslaw (2013-06-17 13:50:17)Sorry maybe I need more explain here. When I switch to TTY terminal from KDE environment (ctrl+alt+F2) I would like to have video signal.
I'm docking laptop and connecting via DisplayPort to DVI.
It's working on lower 3.0 LTE kernel but not on last kernel version (my current is 3.9.5.1).
On VGA connection working fine.

"cat /dev/audio" as solution to strange audio-noise?
With my Macbook Pro (2,2), I hear a strange noise when I connect a loudspeaker to the earphone output that isn't there when I use the internal loudspeakers.
The issue vanishes when I listen to music for example. And appears again as soon as I clouse the player.
interestingly, when I enter "cat /dev/audio" in a console, then the noise disappears! And I can still listen to music and everything else!
I see then many lines of something like "
|z{{{{{{{{|{{{{{{z|{z{{{|{{{{{{{|{{|{{|{{{{{{{|{{{{|{{{{{{||{{|{{{{{|{{{{{|{{{{{|z{{{"
Any idea what the problem could be?ebonyhack!!! You genius!!!
I've recently bought brand new quad core beast, with loads of memory, twin 20" cinema screens, apogee duet, Logic Pro Studio 8, Novation keyboard with automap. The reason I bought this lot was because it is all designed to work seamlessly with each other. And with a mac (my first ever), it wouldn't have all those lovely windows / PC issues I had to put up with for years.
Setup was an utter doddle - easy peasy - it all recognised the other components and worked like a dream, until ............................... first song, three instruments, three audio tracks, HUNDREDS (I am not exaggerating) of error message 10011! It is impossible to record vocals when the darned track keeps crashing! Vocalists get very annoyed. Critical listening to your mix is a complete joke, so you waste hours - no - days of your life bouncing, listening, changing the mix, bouncing, etc, etc, etc.
I have gone through so many of these threads, trying all the "fixes" offered, with no success at all.
Just read this thread, unticked that I/O box, loaded up three songs into memory (just for fun!), played the one which crashed most frequently, waited, and waited .............. and waited - and it played right through! First time since I'd got more than the first track or two written! Did the same with the next song - worked perfectly!!!
Early days as yet, but thanks so much - I love you. -

[SOLVED] How To Read Data Over /dev/ttyUSB0
So...I am using a serial device connected to a Keyspan Serial-to-USB adapter and plugged in to my computer's USB port. The device is constantly sending 115200 baud data over UART, with no parity, 8 data bits, 1 stop bit, no flow control, and no handshaking. I can read the data just fine on my Windows machine (once I install the Keyspan driver). On Arch64, I notice that when I plug it in, /dev/ttyUSB0 shows up so I believe that means the kernel is recognising the device and already has drivers to handle it. I would like to simply see the output of the device through my terminal emulator so I have written the following script....
stty -F /dev/ttyUSB0 115200 cs8 -cstopb -parenb
while true; do
read LINE < /dev/ttyUSB0
echo $LINE
done
When I run this script as root, however, I get no output. I have also tried appending "-icanon min 1 time 1" to the stty arguments list but also to no avail. Can anyone help? Thanks!!
Last edited by tony5429 (2009-10-30 20:59:30)Thanks, all for the responses!
perbh: I wasn't sure exactly how to implement your suggestion. If the cat line doesn't use the variable, "$LINE", how can "echo $LINE" work? I am probably missing something simple...
Well, I have had a little success. The following script creates blank lines whenever data comes in through the usb device. Basically the device sends FFT data whenever it hears a sound which is greater than a certain threshold, so when I snap my fingers near it I see the FFT data show up in Terminal on Windows. Now, with the script below, if I snap my fingers my Linux machine outputs a bunch of blank lines so basically I just see my linux terminal emulator scrolling whenever I snap my fingers Does anyone have any ideas how to get the actual data on Linux? Thanks again!
stty -F /dev/ttyUSB0 115200 cs8 -cstopb -parenb
while true; do
read -n 8 LINE < /dev/ttyUSB0
echo $LINE
done -

Same program ran in DEV&QAS but output data is summarized in DEV??
What could be the causes of having the same identical program ran in different clients with the same variant and same input data but the output is summarized in DEV and not QAS?
Since DEV is not summarized, grand debits and credits are larger in DEV when comparing the two but the net totals are the same.Hi,
Check if the output is an ALV grid output. Then there might be a layout change from DEV and QAS and hence their might be a difference between the outputs. The layout set in DEV wil not be transported automatically. It has to be transported manually.

[solved] fdisk alignment not sticking on /dev/sda1
Hey everyone.
There are several statements that SSDs should be properly aligned.
So i went ahead and aligned my Intel X25-M following this guide on the OCZ forums.
After partitioning the SSD with fdisk using proper alignment, i confirmed via 'fdisk -l' and 'fdisk -lu' that the alignment is correct.
My next step was installing Windows Vista X86_X64, where AS Benchmark again confirmed a proper alignment (128 K as suggested by Theodore Ts'o or 512 K, as suggested in the guide linked above, i tried both).
However, when i checked with fdisk again to confirm the alignment once more, the alignment for /dev/sda1 seems to have shifted. I also get the message, that partition 2 doesn't end on a cylinder boundary.
Right now, it should be 32 heads and 32 sectors per track to result in a 512 K alignment. But fdisk shows 255 heads and 63 sectors/track for /dev/sda1, which is, from what i understand, the standard used by linux. The other partitions seem to be just fine.
I've read that there might be an issue with partition 1 shifting but i also heard it could by avoided by starting partition 1 on cylinder 2 instead of cylinder 1. Unfortunately, that doesn't change anything for me.
Can anyone tell me what i did wrong?
Regards,
demian

Last edited by demian (2010-06-19 09:38:32)You can avoid it by using /dev/sda1 for /boot or swap. You should still start /dev/sda1 in cylinder 2 though.
Also, remember to adjust the offset of all the logical partitions in expert mode. Otherwise they'd start sector 32 as you can see in the bottom code tags in my first post.

I don't know if the <<Driver=(none)>> part is normal here, I can mount/automount whatever other usb devices, like usb flash, or external hdd's, but not the iPod.
Any help would be very much appreciated
Last edited by KBM (2010-07-10 06:29:06)hey guys. I know this thread was "solved", but it didn't solve my problems.
I also got my ipod touch mounted using ifuse and was able to use gtkpod to transfer my files. However, since all of my files ended in .mp3, and the ipod didn't strip the extensions off, I decided to clear them from the ipod and start again.
In the middle of a sync I forgot about it, unplugged the ipod, and now ifuse gives me the message:
No device found, is it connected?
If it is make sure that your user has permissions to access the raw usb device.
If you're still having issues try unplugging the device and reconnecting it.
whenever I try to mount it.
I did the view-the-log thing, and when I plug it in I get this:
Oct 11 08:00:10 localhost usbmuxd[22304]: [2] Could not open device 1-4: -3
So it seems to be a problem with usbmuxd. Any ideas guys?
One more thing, I think I may have accidentally deleted some files from the ipod ("HashTable" comes to mind...), but I did a software update. Would that rebuild the filesystem?
Thanks. -
[SOLVED] ((none)) login/tty and no keyboard after last upgrade?
Hi,
I dual boot and it's been a while since I last upgraded. I booted into Arch, updated everything, and used the system for a few days before rebooting (perhaps a bad call). I just rebooted today and my login prompt is like this:
((none)) tty1
(none) login:
But my keyboard does nothing. No alt+f* to get to a different terminal, no nothing. I have to hard kill the machine. I've tried twice but would prefer not to do that more than I have to. The second time, fsck didn't work so I booted into the Arch install disk and ran it manually. I tried to chroot into my Arch install and re-run pacman -Syu but got transient server failures. Not sure what all needs to be in place to try and do that, though.
Has anyone encountered anything like this before? I get the same behavior with arch and arch fallback. I boot to login prompt, not directly to X so it's not anything to do with that, at least not that I would figure.
So far, the only thing I've been able to find is from 2007 (LINK) but it seemed related to X. I'm going to check rc.conf next time I boot up but wanted to see if there's any other suggestions from someone more experience before I boot up again and potentially have to hard kill.
Thanks for any thoughts/suggestions.

Somewhat embarrassingly, I just found out about manually maintaining *.pacnew files today when researching an unrelated issue. It made me wonder if that was my problem. Perhaps something is goofed in /etc which would explain a ton.
I'm in OS X right now but will reboot shortly and try to fix this issue.
The keyboard issue is troubling as well, though. Some have reported no logins, but often it's a PAM or login manager issue trying to go into X directly. I'm doing no such thing and literally can't get *anything* to work on my keyboard. That makes me wonder...
If I were to boot into the Arch CD and try to run pacman manually... what do I have to do other than
# mount /dev/sda3 /mnt
# chroot /mnt
I tried that yesterday but failed. I'm wondering if I have to mount some other items for that to work. /proc? -
[SOLVED] SATA DVD-RW not in /dev (IRQ problem?)
I have an nForce550 Gigabyte M55S-S3 motherboard, with a SATA HD and a SATA DVD.
I am able to use the HD, but somehow the DVD will not come up in /dev.
Now the HD is present as /dev/sda.
I have played around in the BIOS (as I had to disable some stuff to get sound woring), and I've found that if I disable IEE1394, than Arch will find the DVD drive as /dev/sda, but the HD will be gone (leading to a kernel panic).
Below is the - possibly - relevant part of dmesg. I don't know what the problem might be, but I suspect it's related to some IRQ thing, as enabling/disabling firewire enables/disables the DVD/HD. (Same thing happened with ide/paralell port and the sound card).
Any idea / help is welcome!
EDIT: I've just booted into a Knoppix live CD, with noapic pci=bios, and the DVD was mountable, worked just fine
The same params. did not help in Arch.

Last edited by sessy (2007-01-29 15:16:23)Well, after countless reboots, bios & sata cable tweaking, I made it work
I don't know what the problem was, but putting the HD on SATA II 1, DVD on SATA II 2, plus disabling paralell port in bios, the system booted fine [dvd and sound working too].
The strange thing is that Arch thinks the DVD drive is a HD, and tries to mount it at boot, but I'll live with that. -
[SOLVED] Output of "top" persistent after exit
So, I have been using arch for a couple months, and through my own idiocy I have reinstalled arch. Everything is pretty much back how it used to be (I didn't have a whole lot going on to begin with), except fot the niggling little issue of top's output remaining on the screen after I press q.
I've tried to look through the forum and the wiki (both here and others online) and havent found anything which seemed to be what i am looking for. I'm just hoping someone might know what i've done incorrectly. (I'm assuming this is something I've fat fingered)
I'm doing this all from an ssh session, btw. Also, I don't think it is a local issue as when I run top locally, it behaves as I have always known top to behave.
btw, I have a suspicion this might be a bash issue, but I have nowhere near enough bash configuration experience to know how to troubleshoot this.
Last edited by educated_caveman (2012-07-17 14:45:02)It's a feature, not a bug. AFAIK, top always left behind the last frame when you quit. It makes it easier to spot the process if it's not moving up and down all the time, and to freely copy-paste something without jumping from one line to the next (the list is sorted based on CPU usage). Having it stay still is also very useful if you want to change the niceness level of a program by its PID.

[solved] systemd times out waiting for dev-null.device on encrypted fs
I have a relatively new install of Arch on my laptop. The relevant sections of the drive setup are a luks encrypted root device (with associated unencrypted /boot), and a large ntfs device encrypted with truecrypt. That contains my home directory, which is shared with the Windows 8 dual-boot on the machine.
I have all this mounted on boot, so my typical usage is to enter my password for the encrypted root, followed by the password for the truecrypt-encrypted data drive, then normal login.
This has been working fine for a couple of weeks. This afternoon I rebooted my machine from Windows to Linux, at which point the secondary encrypted drive failed to mount. The root device mounts fine.
On further examination, in the form of journalctl -xb, I'm getting the following errors after mounting the encrypted root device:
Feb 12 21:29:54 kafka systemd[1]: Job dev-null.device/start timed out.
Feb 12 21:29:54 kafka systemd[1]: Timed out waiting for device dev-null.device.

As my root home directory is on the root filesystem, I can still log in as root. If I try to mount or unmount the truecrypt device (located at /data) the command hangs. After removing "auto,x-systemd.automount" from that device from /etc/fstab and rebooting, I have a significant delay at boot, but I can then mount the /data device as normal.
I can't find anything related to this either here or on Google. Any ideas?

Thanks for the warning. Sadly, as there are applications I need for work that only run in Windows, I need to dual boot this machine with Windows 8.1. This is the best option I can find for sharing my home directory, which is also a necessity due to the amount of data I have to share between the systems. I would much rather trust to ntfs-3g-ar and its UserMapping (and all the fiddling with ACLs that I had to do) than to the Windows ext2 drivers I can find. They all seem to be several years out of date. Linux is much better at talking NTFS than Windows is at talking EXT. (To be honest, I'm actually quite impressed with Windows 8 since the upgrade to 8.1. As a long term Arch user and a fan of tiling window managers it's interesting to see Windows moving in the right direction. )
With 'permissions' in the /etc/fstab and the .NTFS-3G/UserMapping file in place it works almost seamlessly. (It took a lot of tinkering with ACLs in Windows and Linux, but it's working very well now. One tip that I'll write here in case it's of use is that you want the last line of the UserMapping file to be a 'generic' mapping. When I didn't have that there were very strange things going on.)
The only two minor problems I have now are:
1) A few applications don't like FUSE filesystems. Steam worked for a while and then broke; reinstalling it failed at every stage. When I checked, it seems that FUSE is a known problem for Steam. (I don't think it's restricted to NTFS.) My response to that was to create /home/.local/$HOME on my root (ext4) filesystem and symlink out to it for troublesome applications.
2) There are a few characters for filenames that Windows doesn't like, making those files inaccessible in Windows. (Colons are the major culprit.) They're usually quite easily renamed. (The exception being my .maildir folder, which I have had to duplicate natively in cygwin.)
Neither of these are anything more than minor niggles. I appreciate the warning, though.
Having said that, if you have an alternative that lets me share a truecrypt-encrypted drive between Linux and Windows that is better than the NTFS-3G approach, I'd love to hear it for future reference.
