Keyboard freezes sometimes ?

[PM]

Using: Debian 4.0, Kde

My keyboard frees (have an interruption) sometimes and not working at all when I'm writing something in Iceweasel (in forums etc).
Keyboard is not working in other program either like Bashconsole, Kedit etc under the keyboard interruption.
It's very strange because my mouse is working just fine when the keyboard interruption appears.
The only solution to solve the keyboard interruption is to log out from Kde completely and log in again, then its working fine.
But it's frustrating.
What is wrong ?

Has it something to do with the keyboard deamon thats not working correctly ?
What deamon is responsible for the keyboard functionality ?

Post your /etc/X11/xorg.conf

Have you done a dpkg-reconfigure xserver-xorg?

[PM]

Post your /etc/X11/xorg.conf

That's the first step in this situations. To see if by changing something, it might affect the rest. Especially when the xorg.conf is not posted.

Your xorg.conf looks fine to me, so it might be something to do with KDE. Although, i use '/dev/psaux' in my Device ps2 mouse.

[Chapter 6]

There's probably nothing wrong with your configuration. You're probably just trying to do more than your system can handle. I have the same problem when I'm visiting certain sites. I will not be able to type anything for a minute or so while my system is busy "doing things".

What are the spec's of your system? Most likely culprit is that you're using a system that is too slow to keep up with the heavy demands you're putting on it, or you're low on memory. You might want to scale down your KDE environment a bit if you're running on an old PC with 256MB of RAM or less. Or, you could try a less resource hungry desktop environment.

If you have a lot of useless processes running, kill some of them. Those little things that monitor the weather or give you a stock ticker, can put a lot of strain on an already taxed system. Add a bloated desktop environment on top of that, with some bloated applications (web browsers, etcetera) and you've got a recipe for a non-responsive system.

Ok, thx all for reply.

I hate intermittent failures there I can't understand the reason for the error.

My machine has the following capacity and has all it need for running heavy applications like KDE and so on.

Motherboard:ASUS A8N32-SLI DELUXE
Cpu:AMD Athlon 64 3700+
Ram:CORSAIR TWINX2048-3500LLPRO DDR SDRAM 2GB
Harddrive:SEAGATE Barracuda 7200.9 300GB SATA 16MB 7200RPM
PCI Express Graphic Card:ASUS GeForce EN7900GT/2DHT/ 256MB PCI
Chassi: COOLERMASTER Stacker 830
Power:SEASONIC S12 600W
Keyboard: ACER 6512-TA

The problem with the keyboard has never occurd earlier.
It is very peculiar.
Well, thx anyway.

[PM]

Sorry Debians ! The problem is back !!!
It happend again when I was in KEdit.
I typed some letters and suddenly the keyboard not responding.
The keyboard was malfunctioning again.
Nothing responded on the keyboard at all when I try typing letters, not NumLock, CapsLock, ScrollLock, nothing works !!!! Keyboard=Stonedead !!!!

I don't like this at all !!!

It'd never happends in Fedora when I used that dist.
Keyboard is fixed when I do a 'Logout' and do 'startx' again in the console only mode.

What is this ???
It's so confusing.
It can't be the hardware 'keyboard' for it is functioning again after a logout/in.

This is a 'tuffy' so I need help on this one !! Sorry !

AMD Athlon and 2GB memory... Hmmm, no idea then... Good luck.

[PM]

Ok !

Maybe I switch over to GNOME and see if the problem persist ...

Is KDE junk or what ?

Sad, because I like KDE very mutch.

[Chapter 6]

I personally don't like KDE, but a lot of people seem to like it -- and they have no problems with it. Given the specs of your system, I doubt that you're pushing it too hard. Do you have a whole pile of crap running on your box?

[PM]

Don't now, here is it anyway.
I don't now what all is and if I need it.

[SlithyTove]

I may be having the same problem as PM. I've been running testing (first etch, now Lenny) for over a year. I use Gnome. Just for the past two weeks or so, frequently keyboard input freezes, randomly. Happens in many different apps: Iceweasel, gedit, AbiWord, Iceape. Mouse is okay. However, if I alt-tab to another app, then back again, the keyboard will become responsive again [note that 'alt-tab' never freezes]. Rarely, this doesn't work, and I have to shut down the app and restart it, which is exceedingly annoying.

It may have started with the same update that killed my nvidia driver, sigh.

I'll try dpkg-reconfigure xserver-xorg.

[Chapter 6]

I never have this problem, and I'm running sid. My keyboard only freezes temporarily in web browsers when I load a page that has a lot of content to be rendered. I don't have to do anything to unfreeze my keyboard though. I just wait 15 or twenty seconds for everything to render.

[SlithyTove]

Okay, dpkg-reconfigure xserver-xorg didn't help.

It's not a problem with too much load on the processor. Random keyboard freeze often happens when cpu usage is close to zero.

[PM]

I seem to not have freeze problem in GNOME only in KDE.
Weird !!!
I suppose it's a bug in KDE then, so I don't use it.

Well, KDE's bug list is long so maybe it isn't fixed yet.
