    Thanks!
    I would uninstall StartUp-Manager. SUM was an excellent tool in it's day, but was written before Grub 2. While portions of it still work, many of the settings do not. Removing it and allowing GC take over its duties will probably provide the best results.

    Part of the problem may be that GC alters the script files and uses the modified scripts (storing the originals in a subfolder) while SUM directly edits the originals. They are most likely conflicting and thus causing the problem.

    Even if GC initially doesn't provide the correct resolution (which I think it will), it will be easier to sort out once SUM is out of the picture.

    Re: HOWTO: Grub Customizer

    Thanks for the guidance!

    I "completely removed" SUM with Synapt.

    Many subsequent reboots with different GC settings leave me with the intermediate-size Grub screen last set by SUM.
    GC continues to rewrite /etc/default/grub as soon as it is saved, but that still has no influence on the grub screen...

    Re: HOWTO: Grub Customizer

    2CV67,

    So you have the resolution you want but only because of what you previously set in SUM?

    If you want to post another RESULTS.txt and tell me what resolution you want(ed) I can review it once more to see if I can find anything new.

    Re: HOWTO: Grub Customizer

    I now have an acceptable resolution but would prefer it bigger.
    Really, I would like to not leave this subject without having control over this parameter, if possible.

    That extended partition was a left-over from a previous setup where I had separate home & root partitions in sda4 - I recently wiped them & did a fresh install of 10.04 without separate home partition, but left it inside an extended, just in case I wanted to change my mind about that.

    Re: HOWTO: Grub Customizer

    2CV67,

    Your current Grub menu should display 800x600 according to the sda3 grub.cfg file.

    If that is the current resolution and you want to experiment to see if grub.cfg now has control over your display, you could open /boot/grub/grub.cfg and change the 800x600 value on line 46. Then save the file (without running update-grub). The resolution should respond to any change you make to that line on reboot.

    If you have used GC for only minor tweaks to grub, I'd remove it completely. I'd like to give you more steps to take from within GC but currently cannot get GC to run on my system for some reason. Step 7 of the original post details how to restore the original files.

    Re: HOWTO: Grub Customizer

    The then current dislay was indeed 800x600.

    Changing /boot/grub/grub-cfg does change the grub screen OK so I can set it that way for now.

    I used GC to set timeout & to only display essential kernels, so I will leave it like that for now.
    I think I could get into more trouble trying to follow the "reversion" instructions than by staying with what I have...

    If there are any subsequent suggestions, I will be very interested to get this working properly.

    Thank you again, very much, for your help!

    Since there is still a bit of uncertainty about how the resolution was/is set, there is one caveat. The setting in grub.cfg will probably be reset the next time you or the system runs update-grub (automatically for kernel upgrades, for instance).

    The setting should be come from the following line in /etc/default/grub. Make sure the setting there matches what you want, since this is where the resolution setting is imported from when things are running correctly.
    GRUB_GFXMODE=800x600
    Note: The /etc/default/grub file may or may not be used with Grub Customizer installed. Some of the scripts are 'proxified' but I don't think the /etc/default/grub file is so the resolution set in this file should be incorported into the grub.cfg file when update-grub is executed.

    Re: HOWTO: Grub Customizer

    Thanks!

    I just tested update-grub and it reset grub.cfg to the last value I had set in SUM before uninstalling it.

    It does NOT take the current value from /etc/default/grub.

    I would like to know where it is storing this old SUM data & how to remove that!

    Maybe I will reinstall SUM & set that value to what I want & hope it will stick through update-grub's...

    I did reinstall SUM & now I can control Grub screen text size with SUM & all the other stuff with GC.

    Messy but it works - for the moment!

    Re: HOWTO: Grub Customizer

    Ok, i havent touched this in ages so barely remember how this stuff works.

    First, have this system been upgraded from an earlier ubuntu version which had grub1?
    Since there is an option when upgrading to grub2 if you want to keep grub1 in mbr and chainload into grub2, my first thought is that maybe grub1 is still used as your first bootloader, and that causes some odd situation.

    If not, i try to explain what SUM could have changed below:

    I should have been sane enough to only set the paths used in this file: http://bazaar.launchpad.net/~jimmy-r...config/grub.py
    Code:
            self.config_file            = '/etc/default/grub'
            self.readonly_config_file   = '/boot/grub/grub.cfg'
            self.update_grub_command    = '/usr/sbin/update-grub'
            self.grub_install_command   = '/usr/sbin/grub-install'

    So as far as i can tell, the only config file it should touch when it comes to grub2 is /etc/default/grub.

    when it comes to resolution, the only lines it should mess with are GRUB_CMDLINE_LINUX_DEFAULT and GRUB_GFXMODE

    So if you change those lines to what you want and run update-grub, anything SUM did change should be taken care of.
