    Re: Screen Blurry/Fuzzy

    What does the xrandr -q command show? If the resolution is 1280 × 800, please provide some further info about the fuzziness -- which parts of the screen it occurs on and the like.

    Still showing wrong res on the command:

    craig@craig-XubuntuLaptop:~$ xrandr -q

    Here is the grub file, if you can check it is all as it should? Maybe I have put something in wrong such as no space, extra space etc:

    GNU nano 2.2.6 File: /etc/default/grub

    If you change this file, run 'update-grub' afterwards to update
    # /boot/grub/grub.cfg.
    # For full documentation of the options in this file, see:
    # info -f grub -n 'Simple configuration'

    GRUB_DEFAULT=0
    GRUB_HIDDEN_TIMEOUT=0
    GRUB_HIDDEN_TIMEOUT_QUIET=true
    GRUB_TIMEOUT=10
    GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash viafb.viafb_mode="1280x800" viafb.viafb_lcd_panel_id=19 viafb.viafb_active_dev=LCD"
    GRUB_CMDLINE_LINUX=""

    The issue is hard to explain, it does appear to be a resolution problem, pictures on my first post explain it, but it is almost like adding extra pixels in, especially text but images don't look right either.

    I do appreciate your help, thanks!

    Re: Screen Blurry/Fuzzy

    What is in
    Code:
    dmesg | grep viafb
    ?
    I need to see if we configured viafb correctly.

    Code:
    craig@craig-XubuntuLaptop:~$ dmesg | grep viafb
    [    0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.5.0-25-generic root=UUID=9ead0ad6-0e02-4484-9f53-20c0834ce14d ro quiet splash viafb.viafb_mode=1280x800 viafb.viafb_lcd_panel_id=19 viafb.viafb_active_dev=lcd vt.handoff=7

    Re: Screen Blurry/Fuzzy

    One more thing we could try... perhaps the viafb driver isn't initialized at all. Let's try this:
    Code:
    sudo nano /etc/default/grub
    ----
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash viafb.viafb_mode="1280x800" viafb.viafb_lcd_panel_id=19 viafb.viafb_active_dev=LCD"
    Change this to:
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="splash viafb viafb.viafb_mode="1280x800" viafb.viafb_lcd_panel_id=19 viafb.viafb_active_dev=LCD"
    Then sudo update-grub . With "quiet" gone, perhaps we'll see more useful messages.

    Done that but no change. Do you want me to run anything else to show if it made a difference.

    Re: Screen Blurry/Fuzzy

    Yes; now that you booted without quite (and hopefully did not reboot since then), try
    Code:
    dmesg | grep viafb
    again and paste it here as there might be more info.
    Because Core 2 is still not to be underestimated.

    Re: Screen Blurry/Fuzzy

    There's one more thing I could think of. Edit /etc/default/grub again, and change
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="splash viafb viafb.viafb_mode="1280x800" viafb.viafb_lcd_panel_id=19 viafb.viafb_active_dev=LCD"
    to
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=viafb:viafb_mode=1280x800,viafb_lcd_panel_id=19,viafb_active_dev=LCD"
    Because Core 2 is still not to be underestimated.
