    Default firefox tabs and menu items dissapear

    Hi all

    For a while i'm experiencing this anoyance with Firefox .
    Some menu tabs and most window tabs disappear in firefox ,
    when i move the mouse over menu and tabs ( where they supposed to be ), they reappear for a moment and disappear again .
    Opening multi window tabs , mostly the second last tab is visible .
    Sometimes i forget and close the previous tab , thinking i close the last page i was looking .
    I'm running KDE3 on 13.1 . Firefox and all up to date .
    I remember a few years back , i had the same problem with an previous distribution but i don't remember the number .
    I got rid of it by distribution upgrade , thats all i remember .
    I was reading a lot about problems with firefox but could not find what i show .
    Seamonkey has it also .
    Chromium , Midori and Opera no problem .
    T.I.A .

    It is probably a graphics driver problem. So you need to tell us what graphics you are using.

    My guess is that firefox is using graphics acceleration that is not well supported for your card. You can try turning off graphics acceleration in firefox, to the extent that is possible.

    Thanks for your quick reply .

    acceleration is turned off , i was trying already turning it on and off , but it has no effect .
    usually i search the internet for answers , but not this time , couldn't find the solution .

    I suggest that you try installing the proprietary drivers for your card.

    I don't have any personal experience with doing that, but others here can probably step in and offer HowTo advice.

    A Radeon 3000 is _not_ supported any more by the proprietary driver.

    Can you reproduce the problem in Recovery Mode? (Advanced Options in the boot menu)

    Can you please install the package "Mesa-demo-x" and post the output of this? (as user when booting normally, not Recovery Mode)
    Code:
    glxinfo | grep render
    Does the problem also occur when you disable Desktop Effects? (Shift+Alt+F12)
    Oops sorry, forget that last thing. That doesn't apply to KDE3.

    Thanks for your time and help , much appreciated .
    I don't use desktop effects .
    Mesa-demo-x is already installed .

    output :

    Code:
    direct rendering: Yes
    OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)
        GL_NV_conditional_render, GL_NV_fog_distance, GL_NV_light_max_exponent

    This means that the radeon driver is not or not fully working, you are using Mesa's software renderer.

    Could you please post the file /var/log/Xorg.0.log?
    This should provide a clue why.

    Right, that is the preferred way here.
    Should have mentioned it, sorry.

    Your log contains this:
    Code:
    [    23.957] (II) RADEON(0): GPU accel disabled or not working, using shadowfb for KMS
    AFAIK this is mostily caused by missing firmware.
    Do you have kernel-firmware installed?

    Do you have NO_KMS_IN_INITRD="no" in /etc/sysconfig/kernel?
