Linux Multimonitors: Chapter 1 Multihead Xinerama

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Ketika gue, eka, dan direz sebagai wakil debconf ikut igos, gue dapat ilmu baru. Gue ketemu master-master dan ketemu sebuah solusi warnet berbasis linux yang hebat:

1 CPU + 1 PS/2 Keyboard + 1 PS/2 Mouse + 3 USB Keyboard + 3 USB Mouse + 1 AGP VGA Card + 3 PCI VGA Card + 4 Monitor + 1 GNU/Linux = 4 Internet Client.

Ketika gue tanya, mereka menggunakan solusi Backstreet Ruby. (Cari sendiri di google). Selain itu, mereka juga mengatakan ada solusi alternatif yang digunakan ubuntu, yaitu Multiseat.

Gue ajak Eka, terus langsung, deh, ngoprek di LAB OS. Ketika ngoprek, kami cuma bisa dapat 2 Monitor+VGA, tanpa USB. Well, akhirnya kita nyoba yang awal aja: Multihead, yang telah disupport X11 secara asli (no patch required).

Yang gue dapat dari hasil percobaan:

    • PCI Card itu dipasang selain di PCI PORT 0 dan PORT 4. PCI Port 0 (port pci pertama) disharing dengan AGP BUS, sehingga PCI VGA Card gak kedetect (bentrok). PCI Port 4 (ato yang terakhir) itu sharing sama port ISA.


      Jangan pernah memindahkan kartu Ethernet, soalnya dia udah pw di PCI 3, dia gak ke deteksi di lain hati eh.. port.


      Multihead itu menggunakan resolusi tertinggi yang didukung oleh VGA card yang paling cupu. Jadi, AGP VGA card ngalah cuma dukung resolusi 640x480 karena si PCI VGA Card cuma bisa sampe segitu.


      Cara mengkonfigurasi X agar mendukung multihead gampang abis, cukup ketik: (as root or sudo)

      # X -configure

      lalu nanti file konfigurasinya akan muncul sendiri yaitu XF86Config-4.new atau xorg.conf.new (tergantung versi X loe). Nah, loe tinggal copy ke /etc/X11 (jangan lupa dibackup dulu berkas yang ada di /etc/X11).

      # cp /etc/X11/XF86Config-4 /etc/X11/XF86Config-4.backupLaYaw
      # cp XF86Config.new /etc/X11/XF86Config-4

      Terakhir, restart X.



    • Eh, kok, cuma satu yang kepake? Ternyata, setelah bertapa lagi, gue cuma harus menambah baris ini di XF86Config-4:


    Section "ServerFlags"
       Option "Xinerama" "TRUE"
    EndSection


    Buaha.. ha.. ha.. jadilah ini:




    Laen kali, jangan menyerah dulu, coba,deh, terkadang jawaban udah di depan mata tapi kita udah keburu nyerah. *SIGH*

      Tenang, Iang, kalo "itu" tandingan jadi dibuat, gue bisa ngasih bahan lebih keren lagi. hehehe :P

      Tolong pinjamin usb mouse dan usb keyboard, dong.

      Btw, laporan apaan, Iang?

      Buat Eka, kapan lagi kita riset? Masih lanjut, nih. Kita belum buat VT (Virtual Terminal), sehingga setiap monitor punya satu login tersendiri.

      kan bisa pake USB-to-PS/2 yang harganya (ditoko deket tempat gue) 20rb... trus, AFAIK, kalo untuk multihead, xineramanya justru di false deh...

    STAN vs. UI

    Ugh, kasihan banget adek gue. Saking kepinteran dia jadi dapet Akuntansi UI dan STAN. Jadi bingung mau masuk yang mana. Beberapa orang (termasuk orang tua gue), menyarankan masuk STAN. Gue malah memperburuk suasana dengan membela memasuki Akuntansi UI, maklum bela almamater. Duh, gue jadi merasa bersalah bikin dia ragu-ragu. Kira-kira enakan masuk mana, yah? Gue juga gak tahu keuntungan masing-masing. Hasil debat sementara: ~ Untuk jangka panjang masuk UI, untuk jangka pendek STAN. ~~Tapi, dia itu kan cewek, ntar pas menikah kemungkinan besar karir terhambat. Eits, ntar, dulu, sekarang kan jamannya emansipasi, bisa aja cowoknya yang jadi BRT. ~ STAN sarang korupsi, kalo masuk STAN jadi pegawai negeri. Kalo mau kaya harus korupsi. Tapi kalo masuk UI, lulus masuk jadi akuntan publik. Sekarang ini, orang membayar akuntan publik untuk memanipulasi nilai pajak dan aset. *SIGH*. Jadi gak ada yang beres ~ dll. Yah, udah gue jadi bingung, apa lagi dia nanya saran gue. Buah, gue gak pengalaman ...

    Installing Goodix Fingerprint Reader Driver on Fedora

    I currently have a Lenovo Thinkpad L14 laptop equipped with fingerprint. I was `belok` from KDE Neon to use Fedora 40 because of someone. Now I am tempted to enable my fingerprint: lsusb | grep -i fingerprint Bus 001 Device 004: ID 27c6:55b4 Shenzhen Goodix Technology Co.,Ltd. Fingerprint Reader Dump the firmware Assuming this is a fresh install, lets do some magic by getting some dependencies: sudo dnf install gcc git python-pip python-devel openssl Let's get the source code: git clone --recurse-submodules https://github.com/goodix-fp-linux-dev/goodix-fp-dump.git cd goodix-fp-dump Create an isolated Python environment: python -m venv .v source .v/bin/activate Do the magic: sudo su pip install -r requirements.txt python run_55b4.py exit There are some python scripts available. I run run_55b4.py because my device ID is 27c6: 55b4 . It will spell some nonsense, which is a good thing. That nonsense actually the firmware captured by our device. Also, I typed exit becaus...

    Chivalry vs Feminism

    Throughout these years I constantly making experiment about how our society perceive about the societal changes. The overhaul of sexist strata and the privilege reformations follow. Note that every change could be perceived as progress or detrimental to the society. The foremost subject that I run is about the opposite of manliness perceived by the oldies vs modern women. The modern era allow women go out from the kitchen into the office. They can have career and enjoy the privilege that men were exclusively had in years. And, can men also do the reverse? Can men also enjoy the privilege of what women do in the past? Can men move from office into the kitchen? And the answer on this era is: NO. While women could reverse their role, men are not allowed to do the same in this society. Society will punish you when a man tries to do that. They will put a healthy man who chose to be at home dad as an irresponsible not-a-man person. If a woman's worth could be rewritten, why not...
