Ubuntu :: CPU Usage Goes Wonkers - Laptop Mostly Unusabl After This / Sort It?
May 21, 2011
This happens at very irregular intervals. A week or two can go by with out this occurring, other times two or three times in one day. When these screenshots were taken, no applications were launched other than Top and Monitor. The laptop is mostly unusable when this is going on.
When I disconnect the wireless, everything quiets down. I can reconnect the wireless, and everything is back to normal. I have had this problem on two different laptops, with different Ubuntu versions.
When I "middle click" the scroll wheel to enable smooth scrolling in Firefox, the entire machine basically locks up until it scrolls to the bottom of the page. On a long web page, this can take almost a full minute as it scrolls very slowly.
Also, just using the scroll wheel to scroll normally. If I scroll up then back down quickly, it takes quite some time, and the CPU usage spikes under those conditions too.
As a test, I went ahead and loaded Top in a terminal window, set side-by-side with my browser. Once I start the smooth scrolling, I can't stop it. It has to get to the bottom of the web page to quit. Xorg's CPU usage spikes during that time and I can hear the fans starting to speed up.
I just quickly made a long text document in Gedit and tried scrolling through it. Same thing. So it's not limited to any one application.
Anyone experiencing anything like this? It started happening after my last major update.
I've got an Acer Aspire One. I don't like windows. I have used Ubuntu many times in the past and love it. I want to install it on this thing, but it's as minimalist a computer as it gets. No DVD drive or anything. It weighs about as much as a small bottle of soda. I have no access to USB Drives, External DVD drives, External floppies, external anything. I do have a cat but I don't think that's going to help. In fact, he's trying to step on my keyboard Anyway, I know you can do a "Frugal install" off the hard disk but I have absolutely no idea what it is.
What exactly is a frugal install? Can I partition the hard drive and leave my windows alone (Got some data, programs and porn holding me down) with a frugal install?Is there a difference between a frugal install and a fancy high-tech DVD install when it's finished (E.G Limitations, stability, chances of computer asploding)?
Fed up with Windows and ready to become a Linux convert. Here's the only problem:
I've created no less than four separate Live USB distros - all using different USB sticks - yet my HP Pavilion dv7 refuses to recognize any of them as "bootable devices."
1) Have formatted USB sticks in FAT16 & FAT32 - neither made a difference.
2) Have created bootable USB sticks using Ubuntu Minimal Live install; Ubuntu full Live install; PuppyLinux Live install; even a simple gparted live install - none will boot.
3) Have checked & re-checked that BIOS is set to boot first from USB drive device.
4) 2 of the 4 USB sticks are new, fresh out of the packaging; and 3 of the 4 USB sticks are each from different manufacturers - so I'm fairly certain it's not a issue of a particular brand being incompatible, nor is it due to the sticks being corrupted somehow.
5) Each of the 4 live distros appears to have downloaded just fine - all necessary files appear to be in order.
6) Have tried using Unetbootin, Ubuntu's own live usb tool, and 1 or 2 others - all have failed to boot my HP laptop.
7) Have even tried removing all non-essential hardware before booting - even booting with no hard drives installed - system still returns the error "no bootable device detected."
This laptop is only 2 years old; I know it should be able to boot from USB. I can boot from a (rather old) SliTaz distro on CD just fine - but I need a persistent USB stick so I can easily add packages as needed, etc...s.
I have a toshiba laptop with ubuntu 8.10 two partitions one with a crashed xp ubuntu and file storage. my net book is an acer eee with xp. i have the two connected with a crossover Ethernet. I can ping the ubuntu with xp but ubuntu doesn't ping xp. i have the fire wall off. xp ip is /24 192.168.0.100 default 192.168.0.1 ubuntu is /24 192.168.0.3 defualt 192.168.0.1
My fedora 12 laptop will no longer boot properly. i get my bios screen, then the fedora intro screen (with the f / infinity symbol on a blue background) after a brief blank screen, then i get a blank screen with a blinking cursor. i can type things but nothing happens when i do, and the computer never exits out of that screen.
is there anything i can do to correct this problem short of a reinstall? i really hate to lose some of the drivers i went to a lot of trouble to find and install as well as some software and some user files.
p.s.: the last thing i did before the problem was to use yum to install quite a few fonts (xorg-...) but it ran after that and i think even went through one reboot with no problems.
I have a weird problem, i have an LG LCD screen that i connect to my laptop via HDMI through nVidia. I was watching full length movies and everything worked perfectly. So, i got myself a new, slightly bigger LG LCD, and now, when I play a movie, about 20-60 minutes into the movie, my machine just turns off. doesnt even shutdown properly, just turns itself off, as if the power ran out (which it didnt..)
I thought maybe i had too many things installed, or mabe i should wait for a new version.. so i waited till i reinstalled a fresh 10.4 on a new partition, played a movie, and again, the machine just suddenly turned itself off.
i tried looking in the system log viewer, but between shutdown and startup, i see nothing special (besides ALOT of "rt_ioctl_giwscan. 1(1) BSS returned, data->length = 105")..
i tried running 64bit & 32bit and it has the same error.
I'm at wits end...10.04 won't connect to a wireless network on my laptop, and that sort of makes it useless. What is the easiest way to revert back to 9.10? I have a dual-boot system with XP and I'd rather not have to start from scratch.
It looks like something must've slipped the attention of Ubuntu developers as in the previous LTS version laptop suspension after closing the lid worked perfectly fine for me (Dell Latitude D820) while after upgrading to Meerkat it doesn't work any more....well sometimes it does sometimes it doesn't - it behaves sort of like a weather in UK/Ireland ...anyway...is there more information I could provide to you guys or is there something you could give me to point me to the right direction ?
When I close my laptop and open it the screen become grey and blotchy with almost an argyle pattern. This has only started happening after I configured the usb ports to work in my VM. My startup screen also says something about a usb problem, and S for skip and M to manually fix it but I have had no problems with my usb. Oh except for my computer won't start
I've just installed Squeeze on my laptop (Toshiba Satellite C660D - adapter is a Realtek 8188CE) and was following the instructions on debian.org to set up WiFi. I've changed the source list, done the firmware update and the modprobe, but when I get to step 5 where it says to verify that I have a wireless interface, the output from iwconfig just lists lo, eth0 and pan0, all with "no wireless extensions". Does anyone have any ideas what I should do now?
I just installed 10.04 on an Acer 4736 laptop and was prompted for a software update of about 170 MB.
I went through with the update downloads and installation, got an error message of some packages not being found, and clicked on the "close" button on the dialogue to finish with the whole thing.
Now the Update Manager window with the grayed-out package updates didn't go away, and the cursor would always show the "busy" circle thing. I waited for a while, but nothing happened. I tried opening Firefox to check for anything about this on the net, but it wouldn't open.
So I left it alone, and it the screen went black (screensaver, I guess). When I tried to get back to the desktop, I couldn't. Screen wouldn't respond and it stayed black; no password prompt or anything.
Ctrl-Alt-Backspace wouldn't take me back to the login screen either.
I have run into the following problem, after I installed the proprietary AMD/ATI driver for my videocard I've been unable to wake up my laptop after suspend to RAM, it suspends ok (I guess?) but when I try to wake it up the screen doesn't turn on so I have to manually shut down the laptop.
before installing the proprietary driver, it worked ok
the videocard is a Radeon HD 3200, and the processor is an AMD Turion X2 Mobile
I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.
I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code: [root@Zion ~]# df -h Filesystem Size Used Avail Use% Mounted on
Is there any way to monitor one process' CPU usage and RAM usage over time on Linux? I am trying to change to a cheaper VPS and need to work out what level of CPU and RAM I need!
What options should I use when I'm using the sort command to sort the top 5 CPU processes (ps -eo user,pid,ppid,%cpu,%mem,fname | sort ??? | head -5) showing max to min usage?
We switched from unix to linux and we have an old report that extracted data from a database, output to an ascii file and then sorted the results in the file based on different arguments. The report now blows up when it runs,and I can only guess it is because the options for sort on linux differ slightly from unix.For example, here is one of the commands issued from within the report app that ran on the old unix box:
I will eventually rewrite the report to store the data in a local table, but I can simply adjust the options to suit the requirments of linux. Basically, I need to know if this can be a quick fix for the short term.
I am sure that all of us know the result of top command in linux. i want to get the value that the top command return as CPU usage, memory usage. so how do i do(programming relation)?
I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
How do I find out the network usage ie the total amount of data is transferred in or out of my computer (openSUSE 11.2 and gnome) and keep a track of the total network usage?
I was transferring some files from my external USB hard drive onto my laptop (running 64bit Karmic), and my laptop froze up for whatever reason.Everything on the screen stopped and the Scroll Lock and Caps Lock LEDs began flashing.Not knowing anything else to do, I hard booted off with the power switch.At this point, I was concerned if anything on either hard rive would be damagedI booted my laptop back up, and all seemed well until I trued to open my Documents folder.For some reason, Ubuntu will no longer open any folders at allI can't click on ComputerDocuments, Music, etc. When I do, a tab opens in the taskbar that says Opening folder. It stays on screen for about 20 seconds, and then goes away and the folder never opens.The weird part is if I open gEdit and try to load a file, I can see and get to everything.
I connected my HP Pavillion laptop to a 1360x768 Vizio TV. On the TV it displays my laptop but on my laptop it has a black screen. How do I fix it so I can see my laptop screen on my laptop and on my TV at the same time?
I used to be able to do this with this TV as well as my friend's Samsung. I'm using a VGA connector. What should I do to have my laptop screen on my laptop and on my TV at the same time?
I have installed Ubuntu (both 10.10 and 11.04 pre-release) on my laptop but my battery is not recognized and it is detected as a desktop system rather than a laptop. I have tried the cat /proc/acpi/battery/BAT1/state method but the directory doesn't exist. I have tried another guide to paste the battery info into this directory but it doesn't allow me to do that and says that the directory doesn't exist, even though I'm trying to make it. I tried it in root nautilus and even on an install of Lubuntu (with a root file manager) but it still failed to budge. I really don't know what to do as I have tried all the guides on the internet that I could find.
When I change the "When laptop lid is closed" option in Gnome Power Manager to either "Blank Screen" or "Do Nothing" (by manually using gconf-editor), the screen itself doesn't turn off when the lid is closed. Obviously not a huge deal, as I could just change the "idle before sleep" on certain occasions, but I liked that setting it to "Do Nothing" previously would actually turn off the screen when the lid was closed.
I have upgraded my laptop to 10.04 while having my usb-keyboard plugged in.f I boot the laptop without a plugged in keyboard, the laptop keyboard is not working. It starts working as soon as I plug a usb-keyboard in though.Quite annoying if I take my laptop with me and the first thing after booting is to find a usb-keyboard to plug in Does anyone know where can I reconfigure this? [edit]I just found out, that the laptop keyboar seems to be in numlock mode... meaning that the keys [j,k,l] is mapped to [1,2,3] etc
