About WP 3.0 here

Buat para ubuntuers, terutama yang baru menggunakan lucid lynx ubuntu 10.04. Langsung aja ya :
1. Install usb_modeswitch. Kalo saya menggunakan Synaptic langsung, jadinya inet sementara make si Axis dulu buat donlot , package yang akan diinstall adalah 2 buah, seperti gambar berikut :

2. Install Wvdial, kalo ini packagenya agak banyakan.

3. Colok Modem lalu jalankan “lsusb” di terminal, biasanya nanti akan terdeteksi Bus 006 Device 003: ID 19d2:fff5
4. Edit file usb_modeswitch.conf di /etc/usb_modeswitch.conf => gksudo gedit /etc/usb_modeswitch.conf
5. Tambahkan

# ZTE AC2726 (EVDO)
DefaultVendor= 0x19d2
DefaultProduct= 0xfff5
TargetVendor= 0x19d2
TargetProduct= 0xfff1
MessageContent=”5553424312345678c00000008000069f010000000000000000000000000000″

6. Jalankan sudo usb_modeswitch di terminal, lalu jalankan lsusb, hasilnya untuk modem akan terdeteksi sebagai : Bus 006 Device 003: ID 19d2:fff1
7. Jalakan “sudo modprobe usbserial vendor=0x19d2 product=0xfff1″ di terminal
8. Edit file wvdial.conf di /etc/wvdial.conf => gksudo gedit /etc/wvdial.conf, lalu tambah

[Dialer smart]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem = /dev/ttyUSB0
Phone = #777
Idle Seconds = 300
Password = smart
Modem Type = USB Modem
Compuserve = 0
Baud = 921600
Auto DNS = 1
Dial Command = ATDT
Ask Password = 0
ISDN = 0
Username = smart

9. Jalankan koneksi dengan perintah sudo wvdial smart, tampilannya kurang lebih seperti ini :

Selamat mencoba.

Tadinya tak pikir lumayan susah, mesti seting segala macem, gak taunya pas langsung nyoba ternyata superb gampang
Step2 nya mudah kok.
1. Nyalakan Lucid Lynxnya
2. Colok Hape SE W950 dalam mode “Normal Mode”
3. Klik Icon koneksi lalu nanti akan muncul Mobile Broadband.
4. Klik aja tu Mobile Broadbandnya, nanti akan muncul instruksi yang intinya adalah untuk seting apn.
5. Karena saya menggunakan axis maka saya pilih axis
6. Tunggu proses sebentar n viola ….. udah conect deh
7. Lounch Firefox n jalanin tes, waktu pertama kali saya gagal, setelah di cek ternyata proxynya tak seting punya kantor, setelah di no proxy langsung lancar jaya.
Semoga berguna, btw lagi bingung nyari broadband inet nih ….

This post is continuation for my previous post Plymouth Error When Using NVIDIA Proprietary Driver, i still continue searching with uncle google n finally i found the answer. Tha answer is from this site : [Tux’s idyllic life.]. I will summarize it in this post

[Problems/Symptoms/Why-Are-You-Here]
Plymouth splash screen…
* is in low res mode.
* has corrupted graphic
* is decent but can’t switch to virtual terminal or VT is horribly in low res mode
* is decent but the splash screen only appears for a brief 1-2 second ( you are missing the dots moving ), before that you only see a black/blank screen

[Environment]
Use Synaptic or ‘apt-cache policy ‘ or common-sense to find out.
* GRUB >= 1.98-1ubuntu5
* Plymouth >= 0.8.2-2
* NVIDIA cards with nvidia-glx-1*
* A clean without other tweaks to plymouth & grub, please revert them before proceeding. Really, it will not work if you insisted on apply other tweaks. !!! IMPORTANT !!!
* Common-sense and google searching skill
* A bit of risk taking spirit and confidence

[Caveats and Limitations]
I will use the uvesafb to fix all the problems mentioned above but I have to warn you about certain limitations first. They don’t affected me much though (widescreen works on mine). I think problem will come when you want to use solar theme or any complex theme as uvesafb doesn’t have acceleration -> slow. Extract from documentation for uvesafb

uvesafb is a _generic_ driver which supports a wide variety of video cards, but which is ultimately limited by the Video BIOS interface. The most important limitations are:
– Lack of any type of acceleration.
– A strict and limited set of supported video modes. Often the native or most optimal resolution/refresh rate for your setup will not work with uvesafb, simply because the Video BIOS doesn’t support the video mode you want to use. This can be especially painful with widescreen panels, where native video modes don’t have the 4:3 aspect ratio, which is what most BIOS-es are limited to.
– Adjusting the refresh rate is only possible with a VBE 3.0 compliant Video BIOS. Note that many nVidia Video BIOS-es claim to be VBE 3.0 compliant, while they simply ignore any refresh rate settings.

Also, uvesafb replaces vesafb in Ubuntu, in case you are wondering.

[Fix/Workaround]
* uvesafb required v86d package to be installed. Hwinfo package is required for the next step as well.
sudo apt-get install v86d hwinfo

* Find out the supported resolution by using hwinfo.
sudo hwinfo --framebuffer

* Edit /etc/default/grub to make sure we boot with uvesafb framebuffer. For the mode_option parameter change to your native screen resolution you see from running the above comment (if not just set to 1024×768-24 which is safest. Oh, Netbook user – please exercise some common-sense here) Non relevant lines are omitted for clarity.

... GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1366x768-24,mtrr=3,scroll=ywrap" ... GRUB_GFXMODE=1366x768

* Edit /etc/initramfs-tools/modules to include uvesafb by adding the following line.

uvesafb mode_option=1366x768-24 mtrr=3 scroll=ywrap

* Force the use of framebuffer:
echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash

* Update and we are done

sudo update-grub2 sudo update-initramfs -u

* Now reboot and enjoy the high resolution sensation . If it works correctly, you should be able to have moving dots with the splash screen; lesser time of blank screen and much more time with splash screen.

I meet some annoying problem in my ubuntu 10.04, after i update my gpu suddenlly plymouth work’s so bad. It looks so ugly then i search help using uncle google. I found article in http://www.sucka.net/2010/03/nvidia-drivers-ubuntu-10-04-lucid-lynx/ n i try it, but i cannot see statement in step 2 in my /etc/grub.d/00_header (i don’t know why ) so i only do step 1. Then i restart my laptop but the playmouth still ugly, it show blank screen when startup n show ugly pic when shutdown or restart. Now i still searching using uncle google, i hope i found the answer so i can shared it here.
