If booting with the default options gives you a blank screen you should select the "Safe Graphics" menu choice when booting from the live CD.
If you are doing a text mode install such as PXE/network then your screen will be corrupted during the process. Workaround and details are at https://bugs.launchpad.net/ubuntu/+source/xresprobe/+bug/127008
Intel video works out of the box, but Nvidia accelerated 3D support is not installed by default. To install Nvidia 3D support click System->Administration->Restricted Drivers Manager
If the above does not work you can install the drivers manually by going to the NVIDIA website http://www.nvidia.com/object/unix.html and download your 32 bit or 64 bit driver and install it manually, for 64 bit that is:
- $ sudo /etc/init.d/gdm stop (stopping the X server)
- $ sh NVIDIA-Linux-x86_64-100.14.11-pkg2.run (depending on the version that will be online)
- follow instructions in the installer
- $ sudo /etc/init.d/gdm restart (restarting the X server)
When using the open source "nv" drivers you can use Administration->"Screens and Graphics" to setup the second monitor
Using the proprietary drivers you must use the Nvidia tool located at Applications->System Tools-> Nvidia X Server Settings
Plugging in an external monitor works, but is a clone of the built-in LCD by default. Following the instructions on this page to extend your desktop to the second monitor does *not* work; it results in the crash described here. According to this post and this bug report, the problem is a new Xinerama implementation and an old config file.
To extend your desktop to the second monitor, you'll want to do what this page suggests (under "Dual-Head config breakage with xserver-xorg-video-intel").
In my case, I have a 1680x1050 built-in LCD and a 1600x1200 external LCD, so I
- added a "Virtual 3280 1200" line in the Display SubSection of the Screen Section in my xorg.conf
- restarted X
- ran "xrandr --output LVDS --auto" to get my built-in LCD to ouput 1680x1050
- ran "xrandr --output VGA --right-of LVDS" to extend my desktop
Fonts on High-Res Screens
On high-res screens (e.g. 15" 1680x1050), the default fonts are too big (Launchpad bug report). You can fix this by following these steps:
- Open System->Preferences->Appearance
- Select the "Fonts" tab
- Click the "Details" button (lower right)
- Adjust the Resolution down to 96dpi
- Make sure you have Subpixel (LCD) Smoothing enabled
- Save the preferences
If you also want small fonts on the GDM login window, you can do this:
- Open System->Administration->Login Window
- Select the 'Security' tab
- Click the 'Configure X-Server' button
- Append '-dpi 96' (without quotes) to the text in the 'Command' field
- Reboot the computer.
The brightness controls do work not out of the box, but they should work once you apply all of the system updates.
However, there now appears to be a bug where the brightness controls stop working after you resume from a suspend.
Until the brightness bugs are finally worked out, you can install "xbacklight" (apt-get install xbacklight), which allows you to set the brightness from the command line and provides a greater range of brightness values.
Nvidia Quadro N140:
The brightness controls do not work, however you can switch to a virtual terminal (ctrl+alt+F1) increase or decrease the brightness and then switch back to X (ctrl+alt+F7) without disrupting the running applications
Audio does not work out of the box, but will work once you apply all the updates.
Microphone may not work with applications (like sound recorder and skype) even though sound can be heard through the speakers or headphones.
Enabling Sound and Fixing the Volume Controls
By default, the sound may be disabled and the volume control buttons on the laptop (up by the ThinkVantage button) and the volume control applet (up by the clock) will not control the speaker volume (they actually control the microphone!). https://bugs.launchpad.net/ubuntu/+bug/136287 this bug report links to a fixed version from an Ubuntu dev a fixed version is available To fix this:
- Right-click on the volume control applet (by the clock) and select "Open Volume Control"
- In the "Switches" tab, make sure "Headphone" and "Speaker" are both checked.
- Close the Volume control.
- Right-click on the volume control applet again and select "Preferences".
- Make sure the device is set to "HDA Intel (Alsa mixer)" and highlight the "PCM" option.
- Close the preferences.
- Select System->Preferences->Sound.
- In the "Default Mixer Tracks" section, make sure "PCM" is highlighted.
- Close the sound preferences.
You should now hear sound and be able to control the volume using the laptop buttons or volume applet.
Intel 4965 users will find that they have a very unstable connection with random disconnects within 30 to 60 minutes of association. The issue is described in this bug report. The problem is with wpa_Supplicant and Kees Cook (An Ubuntu Developer) has posted a fixed version here. The fix should be available via a normal update soon.
The modem works with the Linuxant drivers available at http://www.linuxant.com
To enable bluetooth you must have the thinkpad-acpi modules loaded:
# sudo modprobe thinkpad-acpi
Then su to root (sudo doesn't work unless you put these commands into a script) to enable the root account so you can use su see [This link].
To enable bluetooth:
# echo enable > /proc/acpi/ibm/bluetooth
To disable bluetooth:
# echo disable > /proc/acpi/ibm/bluetooth
The reader works with ThinkFinger. General instructions available here.
Debian packages for i386 can be found at: http://www.rubixlinux.org/debian/thinkfinger/
After the package is installed add the following two lines to /etc/pam.d/common-auth
auth sufficient pam_thinkfinger.so auth required pam_unix.so try_first_pass
Note: Instructions in French available at http://doc.ubuntu-fr.org/materiel/thinkfinger
- Recording fingerprints works
- Login works
- The password must be entered to unlock a locked screensaver
- sudo works
- gksu and gksudo hang : for example it is necessary to run synaptic twice and enter your password upon failure. To be able to use the Finger print reader in the session subsequently, kill the hanging gksu/gksudo process. A workaround is editing the Gnome System Menu (alacarte) to specify sudo instead of gksu/gksudo for the launching command and choose type "Application in Terminal" : this opens an extra terminal window for each superuser application you want to use though.
Trackpad scrolling works out of the box in the standard thinkpad way: Slide your finger up and down the very right edge of the trackpad.
To enable using the middle mouse button to scroll, add the following lines to the "Configured Mouse" section in /etc/X11/xorg.conf:
Option "EmulateWheel" "true" Option "EmulateWheelButton" "2"
Blank Screen Fix
You may get a blank screen when resuming from suspend or hibernate (Launchpad bug report). If so, try editing /boot/grub/menu.lst, adding "acpi_sleep=s3_bios" (no quotes) to the "defoptions" list so that it looks something like this:
## additional options to use with the default boot option, but not with the ## alternatives ## e.g. defoptions=vga=791 resume=/dev/hda5 # defoptions=quiet splash acpi_sleep=s3_bios
Once you have edited the line and added the acpi_sleep parameter, you need to run
$ sudo update-grub
Note that if you get the blank screen upon resume, a quick-fix is to switch to a console (Ctrl-Alt-F1) and then back to X (Ctrl-Alt-F7). This will usually bring the display back to life. However, the long-term fix is to add the acpi_sleep parameter as shown above.
Intel 3495ABG Wireless
Works fine out of the box.e, the wireless card won't come back up. When the [quirk checker script] is run, it says:
CRITICAL ERROR: Use the mac80211 iwl3945 driver instead. ipw3945d is closed source sometimes hangs on resume.
The iwl3945 driver generally only works for about 30 minutes to an hour due to a bug with wpa_supplicant see the section above on the IWL4965 for instructions on fixing this issue
Items that work out of the box
Intel Video: 2D and 3D acceleration works
Nvidia: 2D works, 3D requires the installation of the proprietary drivers
Wireless: Atheros cards work, see this section for a note regarding Intel cards
4-in-1 card reader
- Fn-PgUp activates/deactivates the thinklight
- Fn-Up will trigger stop on a media player
- Fn-Down will toggle pause and play on a media player
- Fn-Left/Right go to prev/next tracks on a media player
- Fn-F2 properly locks the screen
- Fn-F3 shows remaining battery
- Fn-F4 suspends (to ram)
- Fn-F12 hibernates (to disk)
- PrtSc opens the screenshot dialog
All docking station models should work and the following features have been tested:
- DVI or Analog video: You can switch to it using "Administration->Screens and Graphics", if you are using the proprietary Nvidia drivers you must use the Nvidia Control Panel.
- Network Pass-through
- Modem Pass-through
- USB ports: Connected upon docking
- PS/2 Ports
Items that don't work
- Wireless USB/UWB - https://bugs.launchpad.net/ubuntu/+bug/136287
- USB ports can end up temporarily disabled - https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/126369
Gutsy is the first version of Ubuntu to feature a tickless kernel (i386 only, not in AMD64 yet). Power consumption can be monitored using the powertop tool under Ubuntu and using Lenovo battery monitor under Windows.
$ sudo apt-get install powertop $ sudo powertop
I couldn't find any difference in power consumption between the i386 tickless kernel (even with 70ms average sleep in C4) and AMD64 kernel (2ms average sleep in C4). It would be expected that considerably less power would be consumed for the i386 tickless kernel.
There is also a graph available by Right-clicking on the battery icon and selecting Power History.
These are the figures measured on a T61 15.4" 1680x1050 screen 7300 processor (2GHz) 2GB RAM, Intel X3100 graphics with 4965 wifi, Bluetooth and UWB.
|12.3W||Windows XP Pro, all radios on, about 50% brightness|
|16.7W||Gutsy, all radios on, 50% brightness|
|19.6W||Gutsy, all radios on, 100% brightness|
|14.2W||Gutsy, all radios on, 10% brightness|
|-1.0W||Turning the physical radio switch to off on the front reduces power consumption by 1 watt.|
Adding the Nvidia card increases the laptops power requirements.
