Thread: Blackscreen after 11.3 update

  1. #1

    Default Blackscreen after 11.3 update

    Hi,

    i just upgrade my system (64 bit) form 11.2 to 11.3 (via zypper).

    Since the upgrade, suse boots only in text mode. I installed the ATI drivers (ATI Radeon HD4890), now i only see a backscreen after the suse bootscreen.

    The system seems to boot correctly. I'm able to connect normally to the fts-server which is running on the machine.

    I even can't boot in runlevel 3, when i try to enter the bootloader, i only have a flashing coursor in the upper left corner, and a green square followed by a "" centered a few lines below.

    I have no idea how to go one..... i'm pleased to any help.

    regards tjuxx

    I am a bit surprised you can not even boot to run level 3.

    Did you read the release notes for 11.3 and follow the advice there ? For example, try the boot code (in the grub menu): nomodeset

    I bet you are in runlevel 3. Try to ssh to that computer and type
    Code:
    runlevel
    Also, what happends if you press CTRL-ALT-F2 ?

    what is the right way to enter the grub menu??

    i tried to press "3" or "shift". In both times i only see the described coursor, the green square an the "" the boot process seems to halt.

    i already tried CTRL-ALT-F1 to F6, it happens nothing.

    I'm able to connect via ssh. runlevel returns "N 5"

    You lost the console then.

    So you're in runlevel 5. runlevel 3 would work too and that's the next thing you should try, together with nomodeset.

    You can escape the gfx screen by pressing <esc>, than edit an entry before booting. But to boot in runlevel 3 and nomodeset, you just have to append "3" (preceeded by space) to the Boot Options. The same goes for "nomodeset" (append the word "nomodeset").

    oldcpu posted a nice picture somewhere ...

    * First try "nomodeset". If it doesn't help, try "nomodeset 3".

    @tjuxx
    I told you he had a nice picture.

    @oldcpu, IMHO you should put this picture in a sticky howto somewhere (or maybe you did already and I don't read the howtos.)

    in the grub menu i have the following options:

    openSUSE 11.3 - 2.6.34.7-0.7 (default)
    Failsafe -- openSUSE 11.3 - 2.6.34.7-0.7 (default)
    Desktop -- openSUSE 11.3 - 2.6.34.7-0.7
    Failsafe -- openSUSE 11.3 - 2.6.34.7-0.7 (desktop)
    Desktop -- openSUSE 11.2 - 2.6.31.14-0.6
    Failsafe -- openSUSE 11.2 - 2.6.31.14-0.6

    The third one. You could also try the first one and if one of those works remove the other using the Yast or zypper.
