I've install FC14 on my iMac 27" i7 and I'm having exactly the same issue I had with Ubuntu 10.10: acpid eats 90% of one Core all the time.With Ubuntu this issue was solved by updating but with FC14 no way, I can't find any solution.Right now I've turned off acpi and apm at boot time but this only let me use one of my four Cores.

View 1 Replies View RelatedI have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?
When executing the following command

Its a default install of ubuntu server 9.10 with default sources.list for australia. Its a very old computer though, here are the specs:
Pentium 2, 333MHz
Motherboard Chipset Intel 82440LX/EX
ACPI is : Not Supported according to some system detection software I have, is that the reason?
Is there another way to get the computer to shutdown safely when the powerbutton is pressed, instead of power loss occurring?
I am in school for my CIS degree and the book I am using this session covers Windows XP and Fedora Core 4. I am having trouble finding & downloading Fedora Core 4. My question is: Is there a big enough difference between Fedora Core 4 and Fedora Core 14 that I would not be able to use 14 instead of 4?
View 14 Replies View RelatedI have followed this guide to setup automatic screen rotation on a fresh installation of Maverick on a Lenovo X200t. This involves creating the file:
Code:
$cat /etc/acpi/events/x200t-swivel-down
# /etc/acpi/events/x200t-swivel-down
# called when tablet head swivels down
event=ibm/hotkey HKEY 00000080 00005009
action=/etc/acpi/x200t-swivel-down.sh
and the script
Code:
$cat /etc/acpi/x200t-swivel-down.sh
#!/bin/sh
/usr/bin/xrandr -o inverted
touch /home/nikos/Desktop/swivel-down
xsetwacom set "Serial Wacom Tablet stylus" Rotate half
xsetwacom set "Serial Wacom Tablet touch" Rotate half
xsetwacom set "Serial Wacom Tablet eraser" Rotate half
(similar for swivel-up)
What I find strange:
- calling the script with ./x200t-swivel-down.sh works (both with and without sudo).
- rotating the screen to tablet mode only executes the touch commands (which I entered for debugging)
Obviously, the acpi event is registered correctly and reacted upon. Just why are the xrandr and xsetwacom commands ignored?
Just migrated to stretch, and noticed we're not using acpid anymore. Had couple of scripts at /etc/acpi/events listening for some events. What would be the alternative with systemd?

View 6 Replies View RelatedI have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?

a little before 2:45 PM I had my RAM eaten. Going back through my brain I remember that at that time I ran the command VBoxManage clonehd XXXXX.vdi to clone one of my virtual hard drives. I tried this again to make sure that the VBoxManage clonehd command was really the thing that was eating my RAM and it was. My question is - how do I reclaim the RAM. When the process that ate all the ram finished (I think it's the VBoxSVC process) it just leaves me with all my RAM used. How do I free up the RAM without restarting the server?
I have now installed Wheezy on two different hard drives and in each case it seems only one CPU of my dual core CPU computer is recognized. System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.

I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.

No doubt Psychess is a very nice game for playing chess. I was playing this game often. But one thing I observed today is Psychess starts to eat 100% CPU right after the moment we start the game. I came to know about this after observing the "System Monitor" applet graph on the panel. This must not be normal because it's common sense when developer develops a software they always consider the CPU usage.. Even when I develop scripts I always give a sleep after heavy resource usage. For the record, I installed DreamChess and it works fine.

/sbin/udevd --daemon eats about 10-15% of cpu which is quite high. I found out that it is caused by AHCI. If I turn it off in bios, udev takes only about 0-1% of cpu (which I consider normal). However turning AHCI off is deadly for Windows Vista (I have dual boot) - it always ends up with BSOD. Actually, I don't even know what AHCI does. Of course I found some information on the net but I didn't found whether there are some advantages for me. Is it worth 10-15% of cpu (consequently shorter battery life)? On the other hand, I have no interest in changing my bios settings every time I boot to Windows so it would be much confortable to have it turned on all the time. The best solution would be to find out why AHCI does this and how to configure udev to avoid it. And I don't know how.I have OpenSuse 11.2, kernel 2.6.31.12
View 1 Replies View RelatedI'm on 9.10 and I use huludesktop often to watch my Hulu queue. Every once in a while (and more so lately) the video freeze and the sound stutters. I then find that pulseaudio is taking 100% of a CPU (I have a quad core AMD 64bit machine). Killing pulseaudio causes huludesktop to continue without sound and a new pulseaudio starts up. I have to kill huludesktop and resume playback and then everything's OK, until it happens again.

View 1 Replies View RelatedI've a program that launches new processes, and wait for them to die before it exits. So, for example, my program is a process, and it launches 3 more processes, and when the 3 child processes end, it will exit.
As you see, at end of the example, the program used a total number of 4 processes.
1 - Now, I'm running this program in a CPU with 4 cores. This means that the program used each core for each process?
2 - How can I know which core the program used?
I'm working on a simple data processing script.My script uses a loop with getline to check for the value on the next line to decide if it's time to terminate the loop.This works dandy, but the problem is that getline eats that line, which then isn't processed by the rules in the remainder of the script (even though I want it to be). To illustrate what I mean, consider this simple gawk script:
