New and Hopefully more clear question

this is NOT a question about some system information program

I NEED to know what framebuffer modes I can add in grub configuration without starting to calculate stuff and testing 1000 command lines (therefore 1000 reboots), as far as I know hwinfo can actually detect those modes

so, what I actually need is (cutting from hwinfo --framebuffer example command below), as you can see is a mode followed by a resolution, and that's all the resolutions this video card support

 Mode 0x033c: 1920x1440 (+1920), 8 bits
  Mode 0x034d: 1920x1440 (+3840), 16 bits
  Mode 0x033a: 1600x1200 (+1600), 8 bits
  Mode 0x034b: 1600x1200 (+3200), 16 bits
  Mode 0x035a: 1600x1200 (+6400), 24 bits
  Mode 0x0307: 1280x1024 (+1280), 8 bits
  Mode 0x031a: 1280x1024 (+2560), 16 bits
  Mode 0x031b: 1280x1024 (+5120), 24 bits
  Mode 0x0305: 1024x768 (+1024), 8 bits
  Mode 0x0317: 1024x768 (+2048), 16 bits
  Mode 0x0318: 1024x768 (+4096), 24 bits
  Mode 0x0312: 640x480 (+2560), 24 bits
  Mode 0x0314: 800x600 (+1600), 16 bits
  Mode 0x0315: 800x600 (+3200), 24 bits
  Mode 0x0301: 640x480 (+640), 8 bits
  Mode 0x0303: 800x600 (+800), 8 bits
  Mode 0x0311: 640x480 (+1280), 16 bits

then I can pick whatever resolution I please, add it to kernel and be sure it will work with no other testing

Later Edit:

PLEASE "dig" your own answer before posting

both this commands return no result

lshw | grep -i frame
lshw | grep -i buffer

lshw knows NOTHING about frame buffer

likewise:

unset DISPLAY
hardinfo 2>&1 | grep -i frame

likewise lspci

conclusion: seems like no one here actually understand what my command actually does ... nasty, remaking the question (check on top)

Start the orginal question:

hwinfo
No command 'hwinfo' found, did you mean:
 Command 'hinfo' from package 'ganeti-htools' (universe)
hwinfo: command not found

apt-get install hwinfo

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package hwinfo is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'hwinfo' has no installation candidate

more exactly I need the result of the following command: (this is from an older system on which hwinfo is still working)

hwinfo --framebuffer

    Which Ubuntu version do you currently use? 12.04? 14.04? 15.04? – Byte Commander Aug 18 '15 at 14:47

hwinfo in Ubuntu 12.04 has been discontinued in Ubuntu 14.04, but later it was recontinued in Ubuntu 15.10, Ubuntu 16.04 and onwards. In Ubuntu 14.04 hwinfo can be installed as follows:

  1. Download libhd21 dependency package for hwinfo matching your OS's architecture from Debian Package: libhd21 (21.6-1).

  2. Download hwinfo_21.6-1 matching your OS's architecture package from http://ftp.debian.org/debian/pool/main/h/hwinfo/

  3. Double click on the libhd21 package that you downloaded to open it for installation in the Ubuntu Software Center.

  4. Now that the dependency package has been installed, double click on the hwinfo package that you downloaded to open it for installation in the Ubuntu Software Center.

  5. hwinfo can now be run from the terminal, including the framebuffer option which can be run using the command: hwinfo --framebuffer For information about other hwinfo options run: man hwinfo

These steps were tested on Ubuntu 14.04.

  • Maybe you can add discover. The manpage of hwinfo references it. – Byte Commander Aug 18 '15 at 14:53

    Doesn't look like discontinued completely. At least looks like reborn since Wily: Wily, Xenial, Yakkety have it back. – Ruslan Aug 24 '16 at 9:54

sudo apt-get install hardinfo

  • Finally someone who realizes Ubuntu users use it because of GUI :) – jave.web Apr 16 '19 at 10:07

hwinfo is an essential util. It is pitty ubuntu team carelessly removed it without fully understanding its implication.

Referring to the post from karel, I was managed to install it on 14.04:

# apt-get install libx86emu1
# wget http://ftp.debian.org/debian/pool/main/h/hwinfo/libhd21_21.21-2_amd64.deb
# wget http://ftp.debian.org/debian/pool/main/h/hwinfo/hwinfo_21.21-2_amd64.deb
# dpkg -i libhd21_21.21-2_amd64.deb
# dpkg -i hwinfo_21.21-2_amd64.deb

If you get errors on the dependencies, maybe u need to install the hal from this repo: https://launchpad.net/~mjblenner/+archive/ubuntu/ppa-hal

# add-apt-repository ppa:mjblenner/ppa-hal
# apt-get install hal hal-info

You can use the vbeinfo or videoinfo command within grub itself to list available video modes.
