This page aims to illustrate issues and (hopefully) solutions encountered while installing Ubuntu 5.10 (Breezy Badger) on a Levono ThinkPad R50e. As usual, caveat emptor.

The configuration of the ThinkPad used is as following:

 Levono ThinkPad R50e 1834-A67 (a Taiwan-specific model?)
   Intel Celeron M 360 (Dothan 1.4GHz)
   Intel 855GM Chipset
   14' XGA (1024x768) TFT
   Intel PRO/Wireless 2200BG Mini-PCI Adapter
   DVD±RW Writer (Not removable)
   Windows XP Home

This page is still under construction.

Installation

Installing the OS was fairly straight forward. I put in the Ubuntu install disc and pressed F12 to bring up the booting device menu. At the partitioning menu I chose to let Ubuntu resize the existing NTFS partition and create partitions it needed automatically. Everything went well and I was able to boot into both Windows XP Home and the Rescue and Recovery partition from GRUB without any extra effort. It should be noted, however, that I did this on a brand new machine. So if you had made changes to your MBR or partitioning table, you might get different results.


Networking

The Ethernet interface works right after installation as expected (eth1). The Intel PRO/Wireless 2200BG Mini-PCI Adapter was detected (eth0), but probably only works with open networks (I didn't have one to test). As my wireless network (Apple Airport Express) uses WPA/WPA2, I went straight on to make ipw2200 work with wpa_supplicant. This turned out to be quite a complicated task since most articles on enabling WPA on ipw2200 in Ubuntu are written for earlier versions of Ubuntu.


I do not use the built-in modem, so I didn't bother testing it. However, it was suggested here that Conexant's driver works.


Power Management

Some webpages have instructions on how to enable SpeedStep support for Celeron M. I don't what they're on, but according to Intel, none of the Celeron M processor support it.


Standby, Sleep and Hibernation

Standby Hitting Fn+F3 blanks the screen and turns the backlight off. It is supposed to lock the screen, but sometimes it doesn't work; I haven't been able to figure out what causes this. No additional changes are necessary. Sleep To make sleeping work, the following changes are needed:

Open a terminal and enter this command:

  sudo gedit /etc/default/acpi-support

And uncomment "ACPI_SLEEP=true" (by removing the # character in front of it)
Then enter this command in terminal:

  sudo cp /etc/acpi/sleep.sh /etc/acpi/sleep.sh_backup
  sudo gedit /etc/acpi/sleep.sh

Replace the line "echo -n $ACPI_SLEEP_MODE >/sys/power/state" with 
(take from Problem with display remaining black after resume):
  
  # change to console 1
  FGCONSOLE=`fgconsole`
  chvt 6

  # safe video state
  cat /proc/bus/pci/00/02.0 > /tmp/video_state

  # sync filesystem
  sync

  # sync hardware clock with system time
  hwclock --systohc

  # go to sleep
  echo -n 3 > /proc/acpi/sleep

  # waking up
  # restore system clock
  hwclock --hctosys

  # restore video state
  cat /tmp/video_state > /proc/bus/pci/00/02.0

  # change back to X
  chvt $FGCONSOLE

  # clean up behind us
  rm /tmp/video_state


Press Fn to wake up. Screen locking works consistently, unlike standby. Hibernation Hibernation works straight out of the box. Press Fn+F12 or choose Hibernation from the logout menu to hibernate.


Display and external monitor

TrackPoint and other peripherals

Volume buttons.


Various Tweaks

Refer to Installing Ubuntu 5.04 on a ThinkPad T43 (1875) for the following tweaks:

 *  Don't slow down boot-up by synchronizing with network time
 *  Don't slow down boot-up when no Ethernet cable is attached
