Boot Display Offset

#1 Post by don922 »

Using Grub to boot Puppy. Running puppy3HD-528.7 and several other puppies.

The screen display when booting is offset to the left so that the first few letters of each line of lettering is not shown.

I want to move the screen display to the right. I don't know how to do this and I can't figure it out - the Grub Manuals are way over my head.

How can I fix this?

While booting, try the Auto Adjustment funtion of your monitor (if it has one, of course).

Yeah, all monitors these days have buttons to allow adjusting the position of the display, although it often takes some hunting around in the monitor's menu system. If the auto-adjust doesn't work, you can usually adjust the position manually with the buttons.

If adjusting the display this way fixes things for Puppy but messes up your dual-booted Windows, you can can fix this from within Windows using the display/monitor app in Control Panel. Get the Puppy side working first, using the monitor's buttons. Then boot into Windows and run the display/monitor app in Control Panel to fix things on the Windows side.

I've never actually had this problem with Puppy, but I did have this problem with a machine dual-booting Windows and LXLE, and using this procedure successfully made both sides happy.

From here:
https://askubuntu.com/questions/54067/h ... resolution

(I modified commands, because Puppy does not need sudo)
Step 1: find the preferred mode

Reboot and press and hold Shift to display your grub. Press C to enter console mode. Then type:

Code: Select all

$ vbeinfo
This will display various stuff how grub recognizes your display. At the bottom is "preferred mode" - in your case it should say 1280x800. Note down the value.

Note: sometimes, some buggy video cards incorrectly give Grub the wrong preferred resolution - if the preferred mode is much higher than you were expecting, then select the nearest mode in the list displayed that you were expecting.

Press Esc to return to grub and press Enter to boot.
Step 2: Setting the resolution in grub

Reach for your terminal and type:

Code: Select all

$ nano /etc/default/grub
find the line

#GRUB_GFXMODE=640x480

remove the # and change 640x480 with the preferred mode you wrote down. E.g.:

Example:
GRUB_GFXMODE=1280x800

save, then type:

Code: Select all

$ update-grub
Note: the preferred mode has to be among those listed by vbeinfo. For example, if your preferred mode is 1920x1080 (a common 16x9 aspect ratio setting), your preferred mode is NOT supported by vbeinfo and may not work correctly. In fact, there do not seem to be any 16x9 modes supported by vbeinfo, as of Ubuntu 13.04. In that case you could try falling back to something common like 640x480, which, it seems most monitors support and vbeinfo supports. Also, not all the modes supported by vbeinfo are necessarily supported by your monitor and you may have to experiment.
The things they do not tell you, are usually the clue to solving the problem.

I will add.

It is better to use Grub4dos boot loader that comes in Puppy.
It is coded specifically for how Puppy works and it offers some good boot options if you need to troubleshoot boot problems with Puppy.

Always a good idea to be using the latest version.

Boot Display Corrected

#6 Post by don922 »

Thank you for the help I corrected the problem by adjusting the monitor.

I will consider switching to Grub4dos. However, I have been using Grub for over 10 years, updating puppy with frugal installs as newer versions are available. Since I started using puppy I haven't used Windows. This works for me because I only use the computer for internet and simple work that retired people have to do.
