    Unhappy Screen blinks

    Hi everone,

    I have a problem with my Dell SP2009W and ATI Radeon HD 3650 and openSuse 11.0 and 11.1.
    The screen turns off and on all the time (turns black). And it started after a complete software update.

    Is there a way to get the old version back or do anyone vahe a another solution?

    Best regards

    May be me but can you try and explain a bit more?

    When you say it goes off and on do you mean the screen blanks as if the
    power management has blanked the screen and you need to move the mouse or
    press a key to get it back or is it blinking randomly as there is something
    wrong with the card or drivers?

    Also what did you upgrade?

    You say software but what, if you mean the kernel got updated then do you
    need to update the ATI drivers?

    This depends on which ones you were using before so let us know please.

    also are you using KDE or Gnome? do you have effects turned on or off? are
    you using compiz or Kwin?

    As you can see we need a bit more info before we can be able to even make a
    guess at the problem let alone suggest a remedy.

    Hi,

    thanks for fast reply.
    The screen turns black for some seconds, and it does not help if I move the mouse ot hit the keyboard.

    I think it was a complete upgrade, I did it from yast and upgrade after a new install of Suse 11.1 and 11.0. I tried both of them. I really don't know which part(package) get upgraded.

    I use KDE 4.1 without effects on. And I do not use compiz, just standard KDE 4.1 from install

    Regards
    Mats

    Hi matts,

    When you installed did you install any drivers for your graphics?

    Did you use the "Oneclick" install or did you use the ATI repository in
    Yast?

    If this is a graphics problem then what might have happened is the newer
    kernel was updated which might be causing problems as you drivers may not be
    compatible.

    When the machine goes black is it as KDE/Gnome is loading or before you get
    to the GUI?

    Also when it appears to crash can does anything happen if you hold down
    Ctrl+Alt and press the backspace twice?

    Does anything happen when you press:

    Ctrl+Alt+F1

    do you get to a terminal?

    If you get nothing at all are your keyboard LEDs flashing or stuck on (
    scroll lock, caps lock, num lock ) if they are then this indicates a kernel
    crash.

    If none of the above gets you to a terminal on the next boot at the Grub
    screen with the choice of O/S`s when you choose the SuSE entry ( if dual
    booting ) type just the number 3 you should see it echoed on the screen in
    the kernel parameter line, this will start the machine in runlevel 3 with no
    GUI, you should get a login prompt.

    Login as root and enter the root password.

    Next run:

    sax2 -r -m 0=vesa

    see if that will get you to the graphics configuration, if it does then
    "save" the config ( do not do anything like change screen size or anything )
    it will ask if you want to test so click OK then it will s ave save.

    You will then get dropped back to the console, type:

    init 5

    and see if you graphics comes up then.

    Lets us know what happens and we will then try and get you running with the
    ATI drivers.

    Hi,

    I did perform a one click install ( always work fine until now).

    Nothing happens when I enter ctrl+alt or ctrl+alt+F1.

    But when I changed session type to TVM the problem disappear and if I choice failsafe.

    Then I did the trick sax2, and now the screen is working fine excpept it refuse to use 1680*1050*60hz only 1400*1050 SXGA+

    Well, I cant't have it all?? Any idea?

    Thank's
    Mats

    Sounds like one or 2 things.

    When the machine was not working did it actually get to the GUI login where
    you put your user password?

    Or did you get the loading screen with the progress bar then it starts to
    flash on and off and then stops black?


    If that is what is happening then it sounds very much like the driver needs
    re-installing, now I have never used the oneclick so am a little uncertain
    if this is going to work 100% ( if I am wrong then no probs you will not
    loose tvm ) use yast and search for kernel amongst the files you should see
    the 2 kernel modules for the ATI card, if so then just mark them to be
    deleted unless it says that there are new ones in that case mark them to be
    upgraded ( I am a bit blurry on this as I don`t know 100% ) but that should
    remove the drivers then use Yast to reinstall.

    See how that goes.

    If that does not work and you are back to square one then repeat the init 3
    sax2 -r -m 0=vesa again.

    Let us know if that helped.

    By the way which desktop do you use and do/did you have effects switched on?

    Hi again,

    I have no problem with the screen before GUI login.

    I have test both KDE 4.1 and Gnome with same result.

    And now I reinstalled from scratch, format all partions and installed without autoconfig checked, downloaded all now availble patches( I think ), took a good look at the parameters for screen an ATI. The system started fine, I got KDE up and running, waited for some min and still fine. Then I logged out and back in again. And then it start again.

    Puhhhh,

    Regards
    Mats

    Are you running the effects, either kwin or compiz?

    If you are getting to the user login screen then after you have logged in
    and the desktop tries to start it is going wrong it looks like a config
    problem, get to a terminal or tvm if you can and use YaST and create a new
    user,

    Try and login as that user to KDE, does that work ( even for a minute or 2
    )?

    Hi again,

    No, I do not use any effects at all.

    And I did create a new user and logged in with KDE3 and it works fine, no problem after 15 - 20 min. Then I logged out and back in to my own account with KDE4 and the problem start after som min.

    So I think I will use KDE 3 until I buy a new video card, it must be some strange with KDE4 and I am not the man to fix it.

    Is there any place to send loggfiles etc. so people with better skills than me can solve the problem?

    If so, what can I do to produce such a logg file and where are they?

    Best Regards
    Mats

    probably the place to start would be the dot file in your non-working home
    it will be a hidden file in a file-manager unless you enable the viewing of
    hidden files in the View menu.

    You should look for a ".xsession-errors" note the "." this is just a plain
    text file with info in it.


    Also look at the Xorg.0.log and messages in /var/log/

    One thing to try to see if we can narrow down if it is a setting in KDE4 or
    KDE4 on your hardware.

    What happens if you log into KDE4 as the new user?

    Is it stable or does that crash as well?

    If it is stable then that will point to a config of your KDE4 in you normal
    user login, this can be further proved by renaming the hidden file in your
    original users directory from ( note do not forget the dot )

    ..kde4

    to something like:

    ..kde4-bak

    Then logout and back in as that user, you should get a standard default KDE4
    interface and see how that goes., if you need to get any data from the old
    directory like e-mail settings and stuff it will still be there.

    Lets see how that pans out.

    If you want to send me the files then just zip them up and send to my
    nickname (at) f2s (dot) com and put the word zaphod in the subject line that
    way my filters will not drop the mail.

    But first check the log file "messages" that there are no entries that might
    give personal info away such as e-mail addresses or IP numbers etc*

    Plus if you can edit out as much as possible to make the files smaller


    * I do not see why you should trust me, even I do not know what I am doing
    half the time and the other half I do not know who I am :-)
