Typing freezes the screen temporarily

[Zorrothustra]

Just reinstalled 10.4 on one of the partitions of my HD. RE-installed cause I kind of messed up the previous installation. Formatted the partition as ext4. Except one major problem everything seems to works fine now. The problem didn't appear in the previous installation (ext3).

When I type the screen freezes for a few seconds every few seconds (only when typing). Rythmbox keeps on playing. Just a crack when the screens becomes active again. Tried closing programs to check if it was program-related. My machine managed to hang even with only Gedit opened. It really seems keyboard related. I have to wait while typing cause it doesn't remember more than a few characters. Extremely unworkable.

I use a Dell Studio 1558. Looked around the forum, didn't seem like anyone else has this problem.

An idea someone ? Except another reinstall that I am about to do shortly without some community help....


Thanks

Did that reinstall in ext3-format. Everything seemed to work fine. Until I installed the proprietary driver for the wireless and the ATI graphics card and rebooted. Same problem again.

Uninstalled the Broadcom b43 driver since the wireless didn't work anyway. Same problem until the rebooted again: typing as it should be.

The problem seems to be in the driver somewhere... No-one else bumped into this ?

Anyway, as long as there is a wire, I can work. Thats what it's all about. Typing is more of the essentials I need for now. But wireless would be nice...

Hi, I have same problem, it appears after 1 year of using, I have Kubuntu 10.04 and wondering if someone know why it does?
I also filled a bug report in launchpad (https://bugs.launchpad.net/ubuntu/+bug/587160)
Please comment here you can confirm it so they can realise it IS a problem.

I have similar problem.
Yesterday I upgraded to 10.04 lucid, and now I see I made mistake - so many problems, that I can't think about anything positive in my this decision now.

I experience freezing typing too on my Acer Aspire 5930G. This happens not right after the system boot though. `top` is showing nothing interesting too, so I believe this is not an application problem. Bu the only proprietary driver installed is nvidia vga, so this is either hardware error (hope is not) or a kernel bug.

Any workarounds/fixes?

Still having this problem. After some time after boot, my keyboard start freezing. Syslog are overfilled with messages about ACPI errors. Any ideas?

[aneganov]

Please someone help! I have to reboot every 30-40 minute, since keyboard hangs and its impossible to continue working. I'm pissed off with this, I have to work but can't due to this!

When I type letters, and keyboard freezes, which happens every 2 seconds or so, sometimes typed keys are missed. This makes it even impossible to type blindly, guessing letters will appear after freeze.

I don't know is this related to freezes or not, but every time when this happens, logs are filled with this messages:

Help

[afauno]

I have the same issue after upgrading to natty... :(

It seems the same as this ubuntu bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/578506

More importantly, a patch is proposed by the kernel guys at https://bugzilla.kernel.org/show_bug.cgi?id=14733
