* There are some configuration problems after installing Ubuntu 7.10 (Gutsy) on the Sony Vaio VGN-B3XP.
  • This page discusses how to fix them.
  • Inspired by [Laptop/Dell/Inspiron/1501/Feisty].
  • Also explains what works and what doesn't

Please feel free to modify the page if you are sure there are some mistakes on the page, or your method is better. Before you fix the problem,please make sure you have configured your Gutsy correctly.

WLAN and wired networks

  • IPW2200 and Intel 82801DB PRO/100 VE (MOB)
  • Both work out of the box after installation

3d, AIGLX and Compiz

Fancy graphics, using an Intel 855GM chipset.

  • Works out of the box, kinda
  • But compiz has problems when suspending under the installed xorg driver, 'intel'
  • when resuming, you'll get the screensaver unlock dialog as normal, but when you type in your password correctly you see a black screen and your mouse pointer, or a corrupted green screen where you can only see window edges.
  • you can get out of this by pressing Ctrl+Alt+Backspace a couple of times in quick succession to restart xorg and compiz, but this is clearly unsatisfactory!
  • to work around the problem, use the older, more stable graphics driver 'i810', and install package '915resolution' to take care of the special 1400x1050 graphics mode on this laptop that the newer driver would ordinarily set up for you:-

$ sudo aptitude install 915resolution make sure it says something about patching some mode to 1400x1050 $ gksudo gedit /etc/X11/xorg.conf and change Driver "intel" to Driver "i810"

  • while you're in there, have a look at the Touchpad section below, and consider adding the lines mentioned.
  • Click on save, and close the window
  • System > Quit, and then log out. You should now be able to log into a more stable session, and suspends, hibernations, and resumes should all work like they're supposed to without messing up your graphics!

Touchpad

  • This laptop has a Synaptics-type touchpad, and you can get better support by installing the 'gsynaptics' package and adding a few lines to xorg.conf to make it more configurable.
  • I find it really slow under Gutsy by default, and nothing the Mouse preferences can do really helps.
  • Edit xorg.conf as before:-

$ gksudo gedit /etc/X11/xorg.conf and add the following lines into the InputDevice section with the "synaptics" driver:- Option "SHMConfig" "on" Option "MinSpeed" "0.66" Option "MaxSpeed" "0.88" Option "AccelFactor" "0.010"

Sound

  • Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03)
  • Works out of the box, but very confusingly
  • By default, the External Amplifier is turned on, which will prevent you from hearing anything! This is a hidden setting in the sound control panel, you need to turn it on:
  • Right-button on the volume icon in the taskbar, and choose Open Volume Control
  • Edit > Preferences, find External Amplifier, and switch it the checkbox to On.
  • A new tab will have appeared in the main window. Close the preferences dialog, go to the new Switches tab, and switch that External Amp off.
  • It's a good idea to turn down the Master/PCM/Headphones sliders to about 33%-50% to avoid blowing your head off when you try the next step
  • Now go to System > Preferences > Sound, and everything should work. Try a few test noises.
  • I like to have the keyboard control Master, Master Mono, PCM and Headphones all together. You can do something similar in the Preferences for the Volume Control taskbar applet.
  • Settings all persist after reboot, so you shouldn't need to mess with the sliders too much.

Hotkeys

  • Work out of the box (including the Suspend-to-disk one). Anyone know what the S1 and S2 buttons are for?

Power Management

  • works out of the box, almost
  • CPU frequency scaling (Pentium M/Centrino): works fine
  • doesn't dim the backpanel's brightness when configured to do so from the power preferences dialog:
  • one workaround is to use laptop-mode to set the brightness for you: see https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/152731
  • a better workaround would be appreciated!
  • Laptop-mode should be enabled. Edit /etc/default/acpi-support and set ENABLE_LAPTOP_MODE=true to enable laptop-mode when on battery
  • If you do this, consider altering /etc/laptop-mode/conf.d/wireless-ipw-power.conf to put the WLAN adapter into powersave mode when appropriate
  • Restart the computer if you do any of the more involved stuff.
