    Black login screen on 10.10 with HP TX2000

    Hi,
    I've been using Ubuntu 10.10 for a while it is so great!

    But for the first time, I've booted my laptop on battery power instead of AC power.

    I have a black screen on the gnome login and i can hear the ubuntu sound. If i press CTRL+ALT+F2 the screen switch from black to the login (terminal version).

    The problem only appear when i boot from battery power...if i boot from AC power everything is fine !!! I can see the gnome login page ... in fact i've reinstalled ubuntu same problem.

    I think it's a bug with the release.

    My laptop is a HP TX2000.

    Please help me, a laptop without battery support is useless !!!

    regards,
    laurent

    I don't know if this helps but when you get to the black screen have you tried moving the cursor about. When my laptop resumes from suspend I have to do that before I can see the login box.

    I've encountered this time and time again -- and I'm NOT using a laptop -- and only on version 10.10.

    What I've had to do to "fix" it (I put "fix" in quotes because it is not permanent), is the following:
    1) Boot into GRUB selecting the Recovery Mode
    2) Select the option to repair broken packages
    3) When done, and the prompt is back, enter "startx"

    That usually gets me a desktop and when I then reboot, the next time, I get a regular desktop screen -- until a few days later, when this starts all over again.

    I tried to raise this as a concern a while back, but I got so soundly "thrashed" for DARING to criticize Ubuntu 10.10 that I've not brought it up since.
    Ubuntu 17.04 Mate, Mint 18.1 Mate; MS Win 8.1, MS Win10 Pro.
    Will not respond to PM requests for support -- use the forums.

    Hi,
    Thanks for your replies!

    No luck with the solutions provided in the thread

    The problem i'm experiencing is a current bug on Ubuntu 10.10.
    Sadly no one picked up the project to fix the bug yet
    On older linux kernel it seems to work ... kind of a regression bug.

    Here's more info: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/578119


    I think maybe a temp (dirty) workaround would be to trick the kernel that the laptop have AC power connected when booting from the battery...

    EDIT: temp workaround...

    when the screen is black switch to tty1 CTRL+ALT+F1 , login then

    sudo /etc/init.d/gdm restart

    it should restart gnome and everything should be fine until the next battery power boot (repeat each boot).

    best regards,
    laurent

    Code:
    wget kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37-rc2-maverick/linux-headers-2.6.37-020637rc2-generic_2.6.37-020637rc2.201011160905_i386.deb
    wget kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37-rc2-maverick/linux-headers-2.6.37-020637rc2_2.6.37-020637rc2.201011160905_all.deb

    hmmm, I have a similar issue on my hp tx1320us and also on the tx2100ed.

    long story short, I cannot offer you a fix but a workaround, mostly a way to login.

    boot as usual,then when you should get to the GDM the screen goes black, you should hear whatever login sound it makes. What you do here is press

    Code:
    CTRl + ALT + F1
    you can either press F2, F3, F4, F5 or F6. it doesn matter. it should then bring you to a terminal login prompt, right?

    Then Press,


    Code:
    CTRl + ALT + F7
    this should take you right up to the gui.
