Wireless keyboard and mouse items usually have an ID code to allow multiple to 
be used in a small area. I have not found any where I can change the ID myself.

This means that you will need a KVM that supports the type of connector. As 
modern PCs all use USB, one with USB ports would be useful.

[gentoo-user] Wireless keyboard mouse

[thelma]

If I use wireless keyboard and mouse from same company can I use them
with three computers?

My space is limited, and the boxes are close to each other; in addition
I have only one monitor.

PC-1: PS/2(Keyboard+Mouse) + DB9 Monitor
PC-2: PS/2(Keyboard+Mouse) + DB9 Monitor

I use KVM switch to control the above two (all wired keyboard and mouse).
Now I have a new additional box:

PC-3: 1 port with (PS/2 Keyboard or Mouse) + USB's DB9 plug monitor.

How to get all three working with one monitor keyboard and mouse.

Hi Harry,

Depends a little, what base you choose. Commandlines tends to be
shorter than for example lines printed with the dmesg command.

To get you an idea, how much "much" is:

# supposing that you have command history enabled with you shell
# prints the bytes count and the number of lines . You only need to
# devide one by the other
> history -1000 | dd | wc -l 

# for the other estimation you can do this

[gentoo-user] kernel config setting for console scroll back

[Harry Putnam]

In make menuconfig, under:
 Device Drivers → Graphics support → Console display driver support
(700)   Scrollback Buffer Size (in KB)

I think the default was 64 but I like a big scrollback buffer.

As you see I set 700 but really didn't have much of an idea what that
would be in lines.

Can any one offer a close guestimate what 700 kb would be in lines.

That is pretty close to 1 mb isn't it?... but still what is that in
lines?  I'm guessing 1 MB might be around 10,000 lines.  Is that even
roughly close... if so I probably should have went higher.

What does vga=794 get you?

I've used `vga=0x31b video=vesfb:mtrr:3,ywrap' with grub:0 a few yrs
and get a nice size (1280x1024x32 [I think]) console but that requires
kernel settings Graphic drivers -> Frame buffer Devices ->

│ │<*> VGA 16-color graphics support
│ │[*] VESA VGA graphics support

I'm not sure if you need the VGA one but definitely the vesa and from
what I read digging around about KMS, you cannot select drivers
under Frame buffer devices if you want to use KMS .. only the ones
under Console Display Driver Support (a bit further down in make
menuconfig)

KMS takes care of that with real hardware, but not so much with virtual

You're supposed to use a video= parameter but I find the old school
vga=794 works for me. The thing you have to learn with using GRUB, or at
least when using grub-mkconfig, is that you don't edit grub.cfg
but /etc/default/grub when you want to add kernel parameters.

yeah, I saw once I looked at the script that it was just little
wrapper.

But I'm pretty sure that somewhere in all the gentoo stuff I was using
there is a little bit that says to run update-grub.

So not knowing anything about what it might do it seemed like
something was wrong.

But you are dead right that it ain't much... and certainly not a deal
breaker.

What can you tell me about how to get an initial hi-res frame buffer
during boot and after when in console mode?

I know how to do it in grub:0.  But I see my first feeble attempt in
grub:2 was total non-starter.

update-grub is an Ubuntuism, not part of standard GRUB. It's only a one
line shell script that runs

grub-mkconfig -o /boot/grub/grub.cfg

Even a large proportion of Ubuntu users would be able to manage without
it.

[gentoo-user] grub:2 first experience with it

[Harry Putnam]

Setup:INSTALLING gentoo(amd64) in VBox vm guest - win-10 (64bit) host
 Hardware: HP xw8600 - 2x Xeon CPU X5450 @ 3.00GHz - 32 GB ram

Installing grub:0 was my first attempt, since I kind of know my way
around that and have never used grub:2. But, ran into several problems
concerning ncurses and gpm and somehow involving competing versions of
perl.

Seemed like enough of a mess to just break down and take the plunge,
going with the flow toward grub:2

The amd64 hand book offered this for emerge --backtrack=30
But apparently that was enough or not the right thing for the
mess I was making.

After going through the pages https://wiki.gentoo.org/wiki/GRUB2
I tried a couple of edits that seemed to be suggested there and some
USE flag changes (didn't record what I did so quickly lost track of
the things and the sequence)

I did have this set GRUB_PLATFORMS="emu" which is suggested in the
help pages.

But in the initial grub commands there was a complaint about not
understanding emu or something to that effect.

So emerge -vC grub:2 and started over.

Got grub:2 installed (Note that I removed the
(GRUB_PLATFORMS="emu") this time and allowed the system to
handle that on its own. Ok, so got it installed alright.

USE flags and GRUB_PLATFORMS came up like this:

  USE="doc fonts nls sdl themes truetype -debug -device-mapper -efiemu
  -libzfs -mount -multislot -static {-test}"
  GRUB_PLATFORMS="(efi-64 pc) -coreboot -efi-32 -emu -ieee1275
  -loongson -multiboot -qemu -qemu-mips -uboot -xen -xen-32

I quit trying to mess with anything except two variables I changed
from the defaults in /etc/default/grub.

/etc/default/grub:
  # Boot the default entry this many seconds after the menu is displayed
 GRUB_TIMEOUT=8
  Changed from 5 to 8 seconds

  # The resolution used on graphical terminal.
  # Note that you can use only modes which your graphic card supports via VBE.
  # You can see them in real GRUB with the command `vbeinfo'.
  #GRUB_GFXMODE=640x480
  GRUB_GFXMODE=1280x1024x32

So I took a stab hoping the vbox screen would allow such a setting.

(Now after the inital boot and  reboot I'm currently installing that
tool to make sure of the graphic setting [sys-apps/vbe-tool])

Back to the way I got here:

Ran install-grub
  (completed successfully)

Attempted to run update-grub, but that script was nowhere to be found.

qlist grub:2 |grep update  shows its not part of grub:2 pkg.

Just to make sure I re-installed grub:2 once more.
Completed successfully.

But no update-grub

Googled up a page that shows what the script is supposed to do; all
pretty basic stuff. 
Ended up writing my own:  I did put a little bloat in it but still
does the same stuff:

  cat update-grub

  #!/bin/sh
  cmd='/usr/sbin/update-grub'
  set -e
  if mount |grep /boot;then
echo "   /boot is mounted .. running 
 exec grub-mkconfig -o /boot/grub/grub.cfg \"\$\@\""
exec grub-mkconfig -o /boot/grub/grub.cfg "$@" && 
if [[ "$?" < 1 ]];then
  echo "$cmd ran successfully"
fi
  else
echo "   /boot is not currently mounted, please mount /boot
 and rerun this command:
  
  /usr/sbin/update-grub"
  fi
  
Maybe that is where I've messed things up.

On boot instead of getting a grub menu, I got a grub command line.
in one of those really small consoles inside a vbox vm.. . the default
console I guess.

I bumbled my way thru and managed to boot the OS, so at least my
kernel config worked straight away for a change.

I'm really not sure at all where to begin trying to debug this.

I can see my self trying different things until "Maybe" something
works

I could really use some more of this lists generous patience and some
kind of scheme to get this working like I want.

[gentoo-user] Bluefish colours

[Peter Humphrey]

Hello list,

Has anyone here any experience of Bluefish? I want to use it in website 
development but I can't. Its menus use a background of very pale grey and a 
text colour of white. Even with a magnifying glass I can't make out most of 
what it's showing me.

How can I tell it to be like everyone else and use black as its default 
working colour?

OK, yes. Indeed I was looking at the init used by genkernel.

Thanks, I've always build my own kernel but was never sure I did include all the basic
