Hello!

How do i change boot2ram default?  so there is no additional keystrokes needed

Open the file "syslinux/syslinux.cfg"
Find the section of the first menu entry "linuxfb". It begins at line 17 with "label linuxfb".
Add "copy2ram" at the end of the line with "append". Its the line 20.
It should look like " append initrd=kernel/initramfs.gz vga=0x317 copy2ram".
Save the file.



Just an additional info, if you don't want to force the framebuffer mode then remove the "vga=0x317".

Best regards
Elmar

hi
just found great with ploplinux for my classroom disk clone operation, thanks for built-in ssh features
As part of unattended async network disk clone operation, i plug usb ploplinux to boot up 40 pc, boot with copy2ram options
without additional steps, then just simply unplug usb from and let the host with source disk to load up the image
so things are great, and wish to be greater now
How do i change boot2ram default?  so there is no additional keystrokes needed
thanks plop

Some Kernel developers think that nobody is using consoles anymore.

However, this patch brings it back.

So this means that there is no chance to scroll when booting UEFI?
I have reverted to plop 19.4, too many "stress" ATM 
Linus should first fix the scroll function. 

There are so many raspberrys and other devices out there which run only on console and they remove this wonderful feature.
They should better fix the framebuffer in general, i had a lot of problems with devices freezing in framebuffer mode.

For legacy i found a "Work a round":
Booting with kernel parameters "vga=1 nomodeset"

Yes, these are the options for the second boot menu entry of the Live Version "Plop Linux text mode" and the first entry of the Desktop Version when you use LILO.

For UEFI:
I can't get ride of the FB device. Tried with "nomodeset", "i915.modeset=0", "vga=1", "set gfxpayload=text" and blacklisting (!) the "fb" modul.
Nothing worked so far, FB is always active 
Any other ideas are welcome!

Legacy text mode is not available for UEFI. Framebuffer is the lowlevel text mode.

This feature MUST came back!
But don't let us waste too much time with talking about that and let's focus on how to work around this.

For legacy i found a "Work a round":
Booting with kernel parameters "vga=1 nomodeset" and changing the font to "lat4-10" is acceptable.

For UEFI:
I can't get ride of the FB device. Tried with "nomodeset", "i915.modeset=0", "vga=1", "set gfxpayload=text" and blacklisting (!) the "fb" modul.
Nothing worked so far, FB is always active

Noooooo! 

I feel the same. Its such a useful feature. It seems the decision came quickly, because it was still implemented in the kernel 5.8.5. but removed in 5.8.11.

Hm, any idea to work around this? Maybe switching to non framebuffer console or something like this?

Either using commands with "less".  Ex. "dmesg | less". With this you have also more options like searching and so on.

Or using the classic text mode 80x25 or 80x50. Its the second option of the Live CD Boot Menu. The classic text mode has the advantage that it is faster than framebuffer, but has less chars. I always choose that mode when I expect a lot of screen output like file copy with "mc" or "cp -avr".


But I think, the feature comes back.

Ok, very bad news. Console without scrolling is useless.

I have bad news. The support for scrolling in the framebuffer mode has been removed. That hurts.

Maybe it comes back in the future.

Cool, you have circled the problem
