    netbook-launcher using 100% cpu


    Hello people, i'm using ubuntu 9.04 netbook remix in my msi wind u100 and works just great. but now i'm having a annoing issue.

    last week i plugged a external monitor to my wind, and after some issues, it worked ok with the 2 displays, but when i got home, the netbook-launcher process is using 100% of the cpu, and is barely usable. when i'm using another app (like yakuake or firefox) and the netbook-launcher goes to background, it stop consuming cpu time, but when i go back to the main screen, it takes full load again.

    right now i'm using the standard gnome desktop, but the new netbook desktop is much better for my wind.

    tks in advance for any help and sorry for my poor english.

    Howdy Chesterman, two things you can do to see what is going on I guess.

    One is to open terminal and type in
    Code:
    top
    and hit enter and see what processes are running the most out of CPU

    Two is to go into Synaptic Package Manager and install
    htop
    and use it to monitor what processes are eating up CPU.

    Also what kind of external monitor are you using and maybe something is configured wrong that is causing the cpu to drive that display even though it was ok at first. Just a guess though.

    Seema like you aren't the only one with high cpu usage even though it is a different distro. Refer to below link.

    the process eating cpu is the netbook-launcher. is the process that run de netbook custom desktop in ubuntu netbook remix.

    when i use the standard gnome desktop, all work normal.

    i dont know if this is relevant, but i think my glxgearsis is too slow
    79 frames in 5.1 seconds = 15.568 FPS
    91 frames in 5.0 seconds = 18.053 FPS
    111 frames in 5.0 seconds = 22.198 FPS

    this is my xorg.conf is very small:


    Section "Monitor"
    Identifier "Configured Monitor"
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    SubSection "Display"
    Virtual 2515 2136
    EndSubSection
    EndSection

    Section "Device"
    Identifier "Configured Video Device"
    EndSection


    i never touched the file. it was auto configured.

    I just encountered the same problem. This part of the xorg.conf was the culprit:

    SubSection "Display"
    Virtual 2515 2136
    EndSubSection

    Run "dpkg-reconfigure -phigh xserver-xorg" as described in the xorg.conf file's comments. It will regenerate the file (without the Virtual stuff) and netbook-launcher should work normally again after restarting X.
