[solved] weird keyboard behaviour

Hi,
i do have a strange problem with my keyboard. Sometimes (i can't reproduce this) the keyboard hangs. For example: if i type an 'a' i get a lot of 'a's on my screen. This is not limited to letters, same happens when pressing the 'enter' or 'backspace' or multimedia-keys.
The magic stops when pressing 'esc'.
A college has the same problem, so i believe that my keyboard is not broken.
kernel: Linux malcolm 2.6.30-ARCH
xorg-server: 1.7.2-2
I couldn't find anything related in the logs.
Any ideas?

same for me, for about one week, on 2 different systems. I'm using KDE4 but some other people reported this problem on Gnome too. It generally stops when I strike the key again a few times.
It happened when I showed someone how cool Linux was, and then it opened 60 occurences of the same images I wanted to cut and paste...

[solved] laptop - weird keyboard behaviour

Hello,
since upgrading to kernel 3.2.1.1 (same with 3.2.1.2) I have a weird keyboard behaviour.
I have to press ESC to leave this weird mode.
This problem is similiar to
https://bbs.archlinux.org/viewtopic.php?id=86026
Do some people have the same problem?
My laptop is Dell Vostro 1310.
// ok... this never was a kernel software issue
// my keyboards shift was just a bit... loosely

Weird keyboard behaviour in TTY

Good evening,
I just reinstalled Arch Linux on a VPS and I am experiencing some weird behaviour.
I created the Arch Image on my local machine and when it was setup with the most basic features I did send it to the VPs company for them to run.
When I connect to this new install with putty over SSH everything is going fine and my keyboard works.
However when I connect via putty to the 'lights out' service of this VPS and thus reach some kind of TTY environment the keyboard behaviour is totally different! I do not mind that my arrows do not work, or that all the F keys are giving me weird characters. But the most annoying of all is that my Return key (or enter how you want to call it) does print the first character of the command I just typed and does a line break. It is incredibly weird and thus I made you guys a photo.
As you can see when I type uptime then the U is displayed on a new line and nothing happens. If I hit return again then the system will say that the command U does not exists.
However if you continue typing as you can see in the second example then in the end you do get what you want. As you can imagine this is not what should happen.
/etc/vconsole.conf
KEYMAP=uk
FONT=Lat2-Terminus16
FONT_MAP=
I also tried to enable keymap in the hooks of mkinitcpio.conf but this did not make any difference. I am not sure if the keymap is the problem, if I load it manually it also does not make any difference to the TTY.
Yet again, via SSH nothing is wrong and all works fine. However when I connect with putty to the 'lights out' service then it goes wrong.
Does anybody have an idea what is going on?
Edit:
Added thumbnail image. Sorry Inxsible

What I understand is that you are having no problems with SSH, but you are having with PuTTY. Is that right? If so, try playing with PuTTY's settings.
I do use putty to connect to SSH and to the 'lights out'-service of the VPS the arch install is hosted. So in my opinion in both cases it should work the same. However the 'lights out'-service looks as if you are directly connected to the machine via a keyboard and monitor. You also will see all the boot information and the services being started. When it is done booting it will display the login view. I believe you call all of what I just explained a TTY, am I correct?
So if I use putty to connect to these services how come the SSH version works but the 'lights out'-version does not?

Weird keyboard behaviour in TO; field

My keyboard behaves very weirdly when I try to enter a second address to the To: field. It will type multiple characters like:
aararararararararararararararararararararararararar
when I hit the letter a once followed by the delete key. I can not enter any second address by typing.
The only way I can additional addresses by using the cc: field to enter the second address and then dragging the address to the To: field.
Anybody else see this?

Not exactly. I posted another (though similar) issue with the address and subject fields in another post: http://discussions.apple.com/thread.jspa?threadID=1248066&tstart=0
So far I and the others that have experienced this problem have not found a viable solution, unfortunately.

[SOLVED] Weird keyboard mapping issue (not hardware)

Hi all,
I'm not a fan of posting in forums, as i usually always find my solution on other topics or fix it myself after hard work. But this time i must admit, this goes beyond my competence (although i'm pretty sure it's a stupid thing i havent thought of lol)
Alright, here it is. After a power failure, i had to reboot... but i had made some nvidia ( -> 195.36) and kernel ( -> 2.6.34) upgrades meanwhile, and i couldn't boot anymore. I fixed that by downgrading, then X didn't want to start so i did the same on nvidia.
Since then, my keyboard layout is messed up. My right alt key behaves as the left arrow (although the left arrow still fonctions well). The down arrow generates down keypress as usual, but followed by a "enter". For example, here is the result of xev after pressing the alt key:
KeyRelease event, serial 46, synthetic NO, window 0x2000001,
root 0x142, subw 0x0, time 133186949, (-682,-202), root:(398,157),
state 0x0, keycode 113 (keysym 0xff51, Left), same_screen YES,
XLookupString gives 0 bytes:
I tried "kdb" and "Keyboard" in xorg.conf, both giving the same result. This is "not too bad", except that i'm a programmer, so i need my brackets lol I can do alt+bracket key... it works, but it generates a left arrow first, so it's kind of a waste of time.
The keyboard is not at fault, it works perfectly on my laptop (both on windows and ubuntu that are on my laptop... yuck lol). I even got a new keyboard yesterday (thanks to my boss stepping on the other one), and it has the exact same behavior... so i doubt it's hardware issue.
Well, that's my situation... and i gave up lol don't know what else to test, so i hoped some1 else would come up with some genius idea.
Thanks in advance!

PS: sorry for my english hehe

I used to have Xorg-1.8 but i had to downgrade along with nvidia, due to nvidia 190 requiring xorg < 1.8 :

[SOLVED] Weird console behaviour

Hi all
There's someting wrong with my console after doing pacman -Syu.
In X everything works fine though.
My console can't display danish characters like æøå, but I'm able to write them.
And the funny thing is that if I write æøå in the prompt like this :
niels ~ $ æøå
and using backspace for deletion I can delete my prompt like this:
nie
Pressing enter brings back the prompt.
First I thought it was a locale problem but everything else works fine ???
I dont know which files should be relevant to this but here is my locales:
LANG=da_DK.iso88591
LC_CTYPE="da_DK.iso88591"
LC_NUMERIC="da_DK.iso88591"
LC_TIME="da_DK.iso88591"
LC_COLLATE=C
LC_MONETARY="da_DK.iso88591"
LC_MESSAGES="da_DK.iso88591"
LC_PAPER="da_DK.iso88591"
LC_NAME="da_DK.iso88591"

LC_TELEPHONE="da_DK.iso88591"
LC_MEASUREMENT="da_DK.iso88591"
LC_IDENTIFICATION="da_DK.iso88591"
LC_ALL=
And my ~/.bashrc:
alias ls='ls -ar --color=auto'
alias x='startx -- -dpi 96'

export MOZILLA_FIVE_HOME=/usr/lib/firefox-2.0.0.12/
And the first part of my /etc/rc.conf:
LOCALE="da_DK.iso88591"

TIMEZONE="Europe/Copenhagen"
KEYMAP="dk.map.gz"
CONSOLEFONT="cp850-8x16"
CONSOLEMAP="8859-15"

Does any of guys out there have any ideas about this ???
I really need to have a proper console setup !!

In my box, using unicode shows danish characters as some ugly questionmarks.
The only way to stop this is to turn off unicode everywhere possible, this also applies to Ubuntu and family.
When some bad coded website shows these questionmarks it usually helps to switch the unicode off in View-> Character Encoding ...
Don't ask me why :-/
Cheers,

Very weird keyboard behaviour

Hi,
A friend of mine has a problem where when he types 1, 2, 3 to 0 numbers, the mac automatically converts it on the fly to words.... "one", "two" etc. It's a brand new mac, he re-installed the OS without migrating old software back and the issue is still there even in the setup screen.
I have never heard of this happening... ever!
Any help greatly appreciated.
Jay

Greetings!
I have the latest OS X (10.5.7) and am having a lot of trouble with FireFox and Opera and even with Safari on certain websites. I'd use Safari exclusively but it always crashes when I accidentally click on an adobe acrobat pdf document.
I am happily typing away on gmail or facebook or any text window on a website and then make a mistake and Iook up and see it hasn't even finished displaying the characters of the next to the last word I typed. It is infuriating to say the least when I am trying to get a message out quickly. Hitting backspace or back arrow is excruciating so I hafta use the mouse to get the cursor on the mistake.
What is going on?! I miss my 8MHz IBM PC w/128KB of RAM. At least it could quickly display what I was typing.

Weird keyboard behavior PS CS3

Hi all,
Every now and then it seems like my keyboard has gone nuts.
This always happens inside PS CS3. After doing some actions, especially when doing a 'Shift-Alt-Arrow key' action (duplicating a layer or group and moving), it looks as if the keyboard goes in some sort of 'Alt-Always-On' modus.
The annoying thing about this is, that regular keyboard-shortcuts for selecting a tool don't work (pressing 't' for the type tool does nothing) but far worse is the fact when you want to move a layer or group of layers they get unwantedly duplicated.
Sometimes this behavior seems to disappear, when I click around my desktop (outside of Photoshop), but sometimes it doesn't disappear. The only thing left to get rid of it is to quit and relaunch PS.
Does anyone else have this problem, and how can it be solved.
This weird keyboard thing does only appear in PS, every other application is not affected by it.
I'm running PS CS3 on Windows XP SP3
I have all updates of PS CS3 installed

Zeno,
I feel so stupid, but that also crossed my mind.
And to be honest, I think that is really the reason.
Why didn't I think of that before...

Weird keyboard in KDE...

I don`t know what have happened, but right now I`ve got weird keyboard in KDE. When I press <Up> KSnapShot is taking print screen. I cannot browse my console commands in terminal, only in Multi-user runlevel. Direction buttons from numeric part of the keyboard 2-4-6-8 took role of the <Up> <Down> ... buttons. [Delete] button is out of order. I`ve even lost control over my HP QuickPlay buttons.
What thing did that?

Spooky keyboard behaviour

This probably doesn't belong in the programming forum, but I'm interested in finding out if someone has had a similar problem. I have installed my app at a client site. The app is run on 9 machines. 7 of the 9 operate fine, but on two of the machines I have strange keyboard behaviour.
Ocasionally the app will stop erwsponding to the keyboard, but will still respond to the mouse and still paints ok. Restarting the app doesn't help. But, if the user opens MS Word, types a few chars and then restarts my app, it operates normally.
One of the machines is a laptop running WinXP home and the other is a Desktop running Win98.
I am using JRE 1.4.2_05 as the runtime and Swing for the UI components.
The only parts of my code I can think of that may interfere with keyboard processing are:
I have a KeyEventPostProcessor which checks for the escape key nad arrow keys
I also have an event processor which looks like this:
     private static final class EventProcessor extends EventQueue {
          public EventProcessor() {
          protected void dispatchEvent(final AWTEvent evt) {
               try {
                    super.dispatchEvent(evt);
               catch (Exception e) {
                    // Catch any uncaught AWT Exceptions
                    try {
                         MedEDI.showException(e);
                    catch (Exception ignored) {
                    getInstance().shutdown();
     }I'm completely foxed as I cannot recreate this in my development environment. Has anyone else come across a similar issue?

Some possibilities:
1. Dirt under the keysIt is only my app (the only java app on the system) that has this trouble, which makes it unlikely that dirt is causing the problem. At one stage I thought that it might be a USB keyboard or keyboard driver problem, but given that one of them is a laptop with XP and the other is a desktop with 98, this seems unlikely too. Especially seeing that the other 8 terminals are all the same hardware and setup as the desktop.
2. Badly-programmed spyware installedNever thought of that. Might not be the problem, but what the hey, it's worth a try. I'll have them check for spyware on Monday and I'll let you know how it turns out.

BCM4322 wireless weird burst behaviour.

I have a Dell studio xps 1340, with the BCM4322 wireless card. Everything work fine with the broadcom-wl driver, however, I seem to get this weird burst behaviour. By this I mean, my network connection seems to be available for only 1-2 seconds before it cuts off and then reactivates another 1-2 seconds later.
I'm running KDE 4.5 using the networkmanager plasmoid. Here is a screenshot of said behaviour:
Can anyone explain to me why this is happening and if I can fix it in any way?

Bizarre keyboard behaviour after 4.2 upgrade

Since upgrading to KDE 4.2 (from 4.1) as part of a system upgrade, my system has been practically unusable due to the bizarre keyboard behaviour within KDE.
Right from the KDM login screen, most of the keys do not work as normal. For most letters, the key has to be pressed twice in order to generate the letter. However, I cannot type anything with a "u" because it is interpreted as a shortcut to undo everything I have just entered! Letter "f" has to be typed 4 times. If I type "h" once it appears; if I type it again it disappears. Letter "l" produces a vertical division in the window. I could go on....
Since my password ends in "u" I even had to change the password in order to login to KDE because the "u" would delete the characters I'd already entered! But once logged in the problem is just the same.
I have tried setting a different keyboard layout within KDE but this made no difference.
I have tried uninstalling and reinstalling KDE.
The problem seems to be KDE related, because outside KDE, in a system console, the keyboard works absolutely normally. And it doesn't seem to be related to the individual KDE user, since as I said, the problem is present as soon as the KDM login screen appears.
Has anyone got any ideas please?

Thanks for the suggestions. Although they did not prove to be the answer, I have now overcome the problem. I suspect it was a one-off caused by corrupted data, probably in the xorg installation rather than KDE. I removed xorg then reinstalled it - some of the pkg files were corrupt and had to be replaced. Then I had trouble starting the X server at all, and had to reinstall several library packages. The system is running more normally now, though I think there are still some data corruptions in there and time will tell whether the installation is salvageable.

[SOLVED] Weird behaviour after formatting USB installation media

Hi, I have noticed this weird behaviour with USB drives I used to install Arch linux with. I format them using fdisk and mkntfs but after replugging them in, the udevil daemon mounts them again as ARCH_2013...[something] and even the directory tree exists! This happens also when I use mkntfs without the -f flag (initializing with zeros). I also checked the other files in /dev/sd* in order to make sure that my drive does not appear twice, but there is only sda (my HD) and sdd (or sometimes sdb, sdc,...) which must be the USB drive, also according to dmesg.
Any ideas?
EDIT: I wrote something about not seeing any files when manually mounting but that was my bad, I only tried mounting /dev/sdb1 but mounting /dev/sdb brought me the same files as devmon showed.

I am assuming you used dd to write the image to the disk. You can use it to remove the contents of the disk as well.
You should make use of the arch wiki, it is quite helpful.
https://wiki.archlinux.org/index.php/US … tion_Media
You can use this to zero out the entire device:
# dd if=/dev/zero of=/dev/sdx bs=8M // x is the letter assigned to the usb drive. Be careful, The dd command is destructive.
It may take a while to zero out the entire disk, depending on the size. After that use fdisk/cfdisk or gdisk/cgdisk to create the partition table and partition.
To create the filesystem type, this one, ext4:
# mkfs.ext4 /dev/sdx // or create a vfat
then create the label:
# e2label /dev/sdx1 USB_STICK_LABEL
Use my suggestion as a last resort. Read the wiki, most of what I have said is in there anyway.

[solved 2] Weird google behaviour since firefox upgrade

Note that I am using a Mozilla build as the Arch version does not work with my preferred interface language.
Could somebody with a current version of firefox possibly tell me if https://www.google.com/webhp?hl=cy loads correctly or not? Be ready to close the tab/window if it seems to keep loading over and over, though.
Note that this will load Google's home page in Welsh so the fact that all the words look funny is expected and not the problem I'm concerned about.
If it works for others, I'll start troubleshooting but I'd like to know it is just me before I do so.
The English page works fine. It is really quite odd.
Last edited by cfr (2013-04-16 23:31:30)

OK. Not so solved. If I am logged into my google account, certain google pages load and reload and reload. Fast enough that google thinks I'm a badly behaved bot and bans me until I fill in a captcha.
I can reproduce it with the main search page in other languages (UK English, US English) and with search results pages and with some other google pages but not all.
The problem is not specific to one machine. I can reproduce it on a Fedora box running a Fedora build of firefox (theirs works in Welsh for some reason though Arch's doesn't).
Clearing cache and cookies doesn't solve the problem except that it logs me out of my account so the problem only manifests later.

Xen dom0 kernel and weird LUKS behaviour

Hi all,
I am having weird behaviour with fresh Xen dom0 kernel and LUKS. Both Xen kernel come from AUR. No errors during kernel compilation or initramfs generation. While booting, system asks for password to encrypted LVM, using normal kernel (2.6.33-ARCH x64) I enter the password - everything is ok. But while booting Xen kernel, kernel says that password is wrong. After entering it 30 times I sure that I didn't make any mistake ;-)
Any ideas what is happening ?

Partially solved. I connected PS/2 keyboard and it worked. But why USB keyboard works on non-Xen kernel ? Any one knows how to make password visible while typing it at boot time ? It might help finding out what's wrong.
