Welcome, Saudaraku

Hi there,

I managed running Xgl + Compiz on a IBM X41 laptop, using DRI with an Intel i915 graphic card. The cube spins smoothly, woggle and 2d ops are obviously far from the results obtained with a NVidia card.
Please note this is a 1st shot, there still has problems with gdm and such, now it’s up to you

Here are the steps :

. Get latest DRI snapshots from http://dri.freedesktop.org/snapshots/, for this test I used http://dri.freedesktop.org/snapshots…x.i386.tar.bz2 http://dri.freedesktop.org/snapshots…x.i386.tar.bz2 and http://dri.freedesktop.org/snapshots…x.i386.tar.bz2

. uncompress the three archives and mv (common, i810 then i915 in this order) directories content to a single directory :

mkdir all
mv common-20060206-linux.i386/* all/
mv i810-20060206-linux.i386/* all/
mv i915-20060206-linux.i386/* all/

. create a temporary X directory

mkdir /home/you/fakeX

. Execute install.sh in the “all” directory

. specify “/home/you/fakeX” as the X11R6 directory

. Copy the content of /home/you/fakeX/lib/modules/ to /usr/lib/xorg/modules/

cp -R /home/you/fakeX/lib/modules/* /usr/lib/xorg/modules/

. Check that the i915 module is loaded

$ lsmod|grep 915
i915 22240 0
drm 80920 1 i915

. Have a look at your dmesg, you should have something similar to :

[4302209.541000] [drm] Initialized i915 1.4.0 20060119 on minor 0:

. In your /etc/X11/xorg.conf, check you have the following

Section “Module”
[...]
Load “dri”
Load “glx”
[...]
EndSection

[...]

Section “Device”
Identifier “Intel Corporation 82915G/GV/910GL”
Driver “i810″
VideoRam 131072
Option “DRI” “true”
EndSection

[...]

Section “DRI”
Mode 0666
EndSection

. If you hadn’t, stop gdm

# /etc/init.d/gdm stop

. Execute Xorg (yes, just Xorg, to figure out if DRI works)

# X

. Have a look at your /var/log/Xorg.0.log, you should see something like :

(II) I810(0): [drm] installed DRM signal handler
(II) I810(0): [DRI] installation complete
(II) I810(0): direct rendering: Enabled

. Start gdm (still using Xorg)

. Check if everything’s OK with your DRI / GLX extensions :

$ glxinfo|grep direct
direct rendering: Yes

FYI on the X41 i tried, i had about 1300 FPS with a glxgears -printfps

. IF YOU SEE a message complaining about libGL when launching glxinfo or glxgears, reinstall libgl1-mesa and libgl1-mesa-dri

. Stop gdm

/etc/init.d/gdm stop

. Start Xgl

# Xgl &

. Hit Ctrl-Alt- to return to the console. Launch an xterm from here

# DISPLAY=:0.0 xterm

. Hit Ctrl-Alt-F7 to return to Xgl

from here, get back to previous threads to launch compiz, gnome-window-decorator and friends

WARNING, I got lots of Xgl segfaults when playing with gnome-session

1. Simpan dan tutup semua aplikasi yang dibuka.
2. Gunakan shortcut Ctrl-Alt-Backspace untuk me-restart GNOME.
3. Jik Ctrl-Alt-Backspace dinonaktifkan, ketik
sudo /etc/init.d/gdm restart
(Lihat Bagian 9, “Mencegah shortcut Ctrl-Alt-Backspace yang dapat me-restart X” [85 ]untuk menonaktifkan Ctrl-Alt-Backspace.)

Tugas ini membutuhkan hak akses administratif (see Bab 2, Pekerjaan Administratif [8]).
1. Jalankan Services Settings: System->Administration->Services.
2. Masukkan kata sandi Anda.
3. Pilih service yang ingin dijalankan, kemudian klik OK bila selesai.
4. Untuk kendali yang lebih besar pada boot-up services, instal bum dari repositori“Universe” (lihat
Bab 3, Menambah, Menghapus dan Memutakhirkan Aplikasi [9]), dan untuk menjalankannya:
System->Administration->Boot-up Manager.

Partisi Windows seharusnya sudah terbaca secara otomatis dari Ubuntu. Jika ternyata belum, prosedur
berikut akan membuat partisi menjadi terbaca secara otomatis:
1. Baca Bagian 7.1, “Memeriksa penggunaan kapasitas cakram dan menilik tabel partisi” [74 ]
2. Pertama buat direktori dimana partisi tersebut akan dibaca (“mounted”):
sudo mkdir /media/windows
3. Sekarang, backup berkas konfigurasi cakram padat Anda dan buka berkas di dalam editor teks
dengan hak akses administratif:
sudo cp /etc/fstab /etc/fstab_backup
sudo gedit /etc/fstab
4. Tambahkan baris berikut di bagian akhir berkas:
/dev/hda1 /media/windows ntfs umask=0222 0 0
Ganti /dev/hda1 dengan nama peranti yang sesuai untuk partisi Anda.
Jika partisi Windows Anda menggunakan sistem berkas FAT32, ganti ntfs dengan vfat
dalam perintah di atas.
Jika Anda mempunyai sistem berkas FAT32, sangat aman untuk mengizinkan akses
baca-tulis. Untuk melakukan hal ini ubah nilai umask menjadi 0000.
5. Simpan berkas (contoh [sample/fstab_automountntfs]).
6. Perubahan akan berpengaruh sesudah komputer di-restart.
