 |
|
For about the last 2 months, my system has been dropping random keyboard events. This is most notable with an xterm (or gnome-terminal, whatever you prefer) open. Basically, sometimes when I attempt to type a command the first letter isn't picked up so instead of 'vi' I end up with 'i'. Sometimes it's not the first letter, but somewhere later in the command. Or, if I press 'up' to retrieve a previous command from my history the CLI locks up and I have to press CTRL-C a couple of times before it is usable again. FWIW, I use BASh. Updating doesn't affect the issue.
I've been using Gentoo successfully for nearly a year (and Linux in general for 7) and I've never had this problem before. Has anyone else encountered it? Any suggestions for a fix/workaround?

- Is your system a laptop? (or in general, which kind of computer/model is it?)
- Do you have the ACPI daemon running?
- Do you have CPU frequency scaling (e.g. centrino_speedstep or other modules) enabled?
- If so, does it help if you disable them? |

System is a laptop (Compaq Evo N610C to be precise) with a P4-2.66Ghz processor.
ACPI is running: | Code: | ubrpngn@localhost ~ $ ps aux |grep acpi
root 9 0.0 0.0 0 0 ? S< 08:19 0:00 [kacpid]
root 3536 0.0 0.0 1608 532 ? Ss 08:20 0:00 /usr/sbin/acpid -c /etc/acpi/events
102 5909 0.0 0.0 2004 848 ? S 08:20 0:00 /usr/libexec/hald-addon-acpi
|
Frequency scaling is enabled. I haven't tried disabling either ACPI or speedstep, but will post back with results.
[EDIT]
The kernel was originally configured for a P4-M; will options like X86_SPEEDSTEP_ICH help or hinder me with a plain P4 on an ICH3 southbridge?
[/EDIT]
[EDIT2]
Setting | Code: | CONFIG_X86_SPEEDSTEP_CENTRINO=n
CONFIG_X86_P4_CLOCKMOD=y |
seems to have fixed the issue, and improved overall system response noticeably. Thanks!
