    Question Screen getsblack after startx and Caps lock LED start flashing

    Hi!

    I have a Acer Aspire 5820TG with Core i5 and ATI mobility radeon HD5470
    When i start the backtrack 5 live cd i have to first change to nomodeset to get the terminal.
    After that i tried to use startx and the screen went black and the Caps lock LED start flashing.
    Tried to wait 40 min to see if it started but nothing happend.
    Then tried:

    rm /root/.kde/cache-root/icon-cache.kcache
    rm /root/.kde/cache-root/plasma_theme_Volatile.kcache
    rm /root/.kde/cache-bt/icon-cache.kcache
    rm /root/.kde/cache-bt/plasma_theme_Volatile.kcache

    But i get the same problem.
    Also tried to change to other things in the "live cd boot menu" like adding
    i915.modeset=1 or i915.modeset=0
    and xforcevesa
    and removing text splash etc.
    But it all leads back to the same problem.

    I use KDE x64 forgot to write that

    Anyone got the same?

    Are you installed the ATI driver?

    I got a Acer Aspire 4820TG and I had the same problem.

    I removed the vga=7xx entry and wrote vesa instead, and startx worked properly.

    Hi

    I installed Backtrack 5 KDE 64 to my hard disk and I have the same issue of blank screen and Caps lock LED.

    I tried

    rm /root/.kde/cache-root/icon-cache.kcache
    rm /root/.kde/cache-root/plasma_theme_Volatile.kcache
    rm /root/.kde/cache-bt/icon-cache.kcache
    rm /root/.kde/cache-bt/plasma_theme_Volatile.kcache


    and

    dpkg-reconfigure xserver-xorg

    and even

    cp /etc/X11/xorg.conf.failsafe /etc/X11/xorg.conf


    Then I tried to install NVIDIA driver but it shows me an error - "Unable to find the kernel source tree for the currently running kernel".

    Hardware config - i5 processor M480 @ 2.67GHz, 4 Gb RAM, Nvidia Geforce GT 420 M

    Pls help me

    Thanks in advance

    Talking Re: Screen getsblack after startx and Caps lock LED start flashing

    finally got the solution

    edit grub menu, delete the word splash and write i915.modeset=1 keep everything as it is....

    then before startx

    rm /root/.kde/cache-root/icon-cache.kcache
    rm /root/.kde/cache-root/plasma_theme_Volatile.kcache
    rm /root/.kde/cache-bt/icon-cache.kcache
    rm /root/.kde/cache-bt/plasma_theme_Volatile.kcache

    and finally backtrack runs on hard disk...

    and then make permanent changes in grub menu after backtrack starts
    go in /etc/default/grub, delete the word splash and write i915.modeset=1

    thats it..

    This works, problem fixed on a R61, thanks. Note: you need to repeat the steps above after apt-get upgrade (with the icons)

    Well I never had to delete the splash line...mine looks like this and resolved the CAPS flashing issue for me:

    GRUB_CMDLINE_LINUX_DEFAULT=”text splash vga=791 i915.modeset=1″

    - To update the GRUB config perform the following:

    cd /etc/default/

    - You can use vi to edit but if you're new to linux I'd suggest nano since it's easier:

    nano grub

    - Now you'll be in the nano editor inside the grub file...find the line that starts EXACTLY like this:

    GRUB_CMDLINE_LINUX_DEFAULT=

    - Make sure there is NOT a # in front of that line. Once you've found the right line make sure everything after the = looks EXACTLY like what I write below INCLUDING the quotes:

    ”text splash vga=791 i915.modeset=1″

    - So your line should now look EXACTLY like this:

    GRUB_CMDLINE_LINUX_DEFAULT=”text splash vga=791 i915.modeset=1″

    - Just to clarify, we're NOT adding a new line but modifying a current one. If that is indeed what you've done hit CTRL-X and it will ask you if you'd like to save your changes. Just accept the defaults for the questions. After you've saved the file you'll be back at the standard command prompt and out of the editor. Now you'll type the following followed by hitting return:

    update-grub

    - This will complete the changes. Then reboot and you should be all set. You can reboot by just typing reboot!
