keyboard slow, laggy, missed keys

Asked by J Demoso

I have a HP Pavilion dv2000 amd turion x2 with 1GB of ram running Ubuntu 11.10 x32. I have just installed Ubuntu and everything is working fine except the keyboard. I can type and all the keys work the problem is that if I type too fast some of the keys I pressed will not show up. If I hit a key twice in a row sometimes it will run a row of that key like 5 or 6 t's in a row. It seems to be laggy or slow. The keyboard works fine under windows. I used to top to make sure no running processes are eating up all of the cpu. I checked and tried all the system settings for the keyboard and universal access to know avail. It also makes no difference if I log in Unity2D or Unity 3D.

Any help would be appreciated!

Should give you the 290 driver which may help. I have the same video chip and the driver works ok

Thanks so much for all your help! The updated driver didn't actually fix the problem. I found out it was a bad battery in the laptop that was causing it. After I tried everything you said and it still was slow I decided to remove the keyboard and make sure it was properly connected. In order to do that I had to remove 3 screws from under the battery and so I decided to leave the battery out when I powered it back up to see if it made any difference. That's when the light bulb went on as typing worked great and I'm starring at the battery on the table.

Again thanks for all your help though!!!

I had the same problem but removing the battery did not work. Nevertheless I had my charger connected, which happens to be a "generic one" and not the original from Lenovo. I removed it and tried again typing something just on the battery and the problem was gone!!!

Thanks so much for the hint!!!

Using generic battery chargers (A/C adapter) already had caused me problems in the past with the touch pad while using Windows.

I hope this other solution can help somebody. (I am usiung Ubuntu 14.04 on a Lenovo G550)
