    flashing/jumping screen after install.

    hello all.

    just installed ubuntu 12.10 on my laptop. HP Compaq CQ60 series. Nvidia Ge8200 G graphics card. The installation went ok but even after rebooting several times the screen still keeps jumping and flashing. Looks like I need a different driver. Please can someone advise how to do this please.

    Also wireless card not recognised. tried dongle, same result. but will open another thread for this.

    Thanks.

    Could you run this again? Make sure to copy exactly the syntax:
    Code:
    lspci -nnk | grep -iA2 vga

    Thanks.

    Since you have an Nvidia card, installing the proprietary driver may provide better support.

    Open a terminal, and run these commands:
    Code:
    sudo apt-get install nvidia-current
    
    sudo nvidia-xconfig
    Then restart your machine.

    The worst case scenario is that you boot into a black screen. Avoid pressing your power button to restart or power down your machine. Instead, you can get into a text-mode console by pressing Ctrl+Alt+F1 (or F2). You can login there using your regular user. There you can restart by running:
    Code:
    sudo reboot
    and turn it off by running:
    Code:
    sudo poweroff
    In any case, booting into a black screen using the Nvidia driver may indicate that your card does not support the kernel mode. To allow compatibility set the flag 'nomodeset' on the grub options.

    While in text mode, edit this file:
    Code:
    sudo nano /etc/defualt/grub
    Look for a like that looks like this:
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    Add nomodeset to it so it looks like this:
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
    Save the file, and reboot.

    Hope it helps. Let us know how it goes.
    Regards.

    Re: flashing/jumping screen after install.

    Hiya papibe.

    Checked the screen resolution (laptop 15") Set at 1024 x768 16.9. changed it to 1024 x 768 4.3 and it initially appeared to stablise but after using it for a few seconds it went bananas. flashing badly when trying to open icons and trying to access the internet produced a really fragmented screen like a digital TV losing signal. Tried setting back to 16.9 but no good.Rebooted to find text appearing with missings fonts and little brown boxes instead of letters, fragmented flashing screen jumping around. Worst of all lost wifi & sound. Reset to 4.3 rebooted and message appeared "System Problem Detected" (reported problem) Shut down. Returned this morning, fired up and screen almost stable but no sound or wifi. Then a text saying updates required. said it would take 2 hours to download. left it, returned 1/2 hour later and laptop had shut down. Rebooted, screen almost stable but showed an error: "Problem with the system," no details, so took the opportunity to open the terminal and input the text .
    [HTML]
    sudo apt-get install nvidia-current This is as far as i got. as immediately after displaying the output the screen froze.

    looks like ubuntu cant find nvidia. had to reboot 6/7 times to get this output and in the course of this, one terminal message. "said unable to locate nvidia."

    On one another "terminal" try, following the incomplete updates, the output included: 6 newly installed, 0 to remove, 0 upgrade, 304 not fully installed. Complete page froze before I could copy.

    Screen kept freezing so could not use mouse to copy, or close terminal. Input sudo nvidia-xconfig = output: assuming driver cache failed/asking for cache data failed. Ctrl alt F1/F2 did not work but terminal responded to reboot and poweroff.
    Tried to run from disks 2 x 12.10 ubuntu, but much the same results. instability, icons slow to open, screen freezing no sound or wifi.

    looks like some options: try to get compatible version of nvidia : --fix missing upgrade, or possibly the best option wipe disk and start again with 13.04. What would you advise please. Thanks

    Re: flashing/jumping screen after install.

    Hi Dont know if this is relevant but wiping windows vista off this machine and replacing it with XP pro has frequently produced wifi & sound problems.

    When XP was installed the device manager showed 2 audio components with no drivers. Windows couldnt supply the drivers and neither could Driver Solutions. Eventually after many weeks of work I discovered that a component was installed in the (vista) laptop in anticipation of HDMI and it could only be mounted off a universal audio architecture platform which was not included in the XP disk.The other driver was a conxent HD Audio 221 but further confusion and difficulty arose until I discovered that in order in to install the conxent driver I had to disable the the HDMI component. Anyway I eventually got the sound working normally but the wifi has always been a bit intermittent and I now suspect that its due to the vista/XP conflict. It works and then stops for no apparent reason.

    Why is it that we can run 20 + different distro/OS on lots of machines and windows cannot make 2 of their own OS run with compatibility on one machine. just stupid.

    Dont know if this would effect how ubuntu "sees" the driver compatibility and its causing confusion.??

    I can wipe XP & reinstall Vista or just wipe windows altogether however your help and instructions are all very very helpful and part of my learning curve. Thanks
