Ubuntu 12.04 has been released almost a month ago and I thought I revive my semi-benched U2010 to see how the hardware support has improved in this new release of Ubuntu.<\/p>\n
First off, if you are installing Ubuntu 12.04 and are getting the dreaded black screen issue, follow the Ubuntu Wiki here<\/a>. Make sure to also install the fix to get suspend\/sleep and hibernate working with the new psb_gfx driver. \/etc\/modprobe.d\/blacklist.conf<\/p>\n The first line disables the stub driver, the second line makes sure you can actually use the backlight keys (fujitsu_laptop conflicts with the psb_gfx driver). To get the microphone working I had to add the following line in \/etc\/modprobe.d\/alsa-base.conf:<\/p>\n The headphone jack sensing\/detection is flacky in this new release. Switching between the headphone jack and the internal speaker will only work after the audio card goes into power-saving mode, ie. a few seconds after the last audio output closed.<\/p>\n \/etc\/default\/grub:<\/p>\n quiet console=tty1<\/strong> is the recommended workaround for the black screen issue of the new psb_gfx driver in 12.04. Finally update the bootloader via:<\/p>\n 2. Installing the Fujitsu Buttons driver (fjbtndrv)<\/strong><\/p>\n In order to get the screen buttons working we will need to compile and install the latest version of fjbtndrv<\/a>. 3. Calibrating the display<\/strong><\/p>\n The touch screen has been supported for several kernel and Ubuntu versions already. The big problem always was the missing calibration tool. Luckily a calibration is now available in form of xinput-calibrator<\/strong>. At last special drivers are no longer required.<\/p>\n Calibrate the display and save the output to \/etc\/X11\/xorg.conf.d\/99-calibration.conf<\/strong> Known problems:<\/p>\n Ubuntu 12.04 has been released almost a month ago and I thought I revive my semi-benched U2010 to see how the hardware support has improved in this new release of Ubuntu.

\nAfter the installation you will have to make some minor adjustments to get everything working on the Fujitsu U820\/U2010:<\/p>\n\r\nblacklist poulsbo\r\nblacklist fujitsu_laptop\r\n<\/pre>\n
\nThe enable_msi fix<\/a> in \/etc\/modprobe.d\/alsa-base.conf is no longer required. The sound will work just fine without it.<\/p>\n\r\noptions snd-hda-intel model=laptop-amic probe_mask=1\r\n<\/pre>\n
\r\nGRUB_CMDLINE_LINUX_DEFAULT=\"quiet console=tty1 acpi_osi=Linux acpi_backlight=vendor nmi_watchdog=0\"\r\n<\/pre>\n
\nacpi_osi=Linux acpi_backlight=vendor<\/strong> is required to get the backlight controls working.
\nnmi_watchdog=0<\/strong> disables the NMI watchdog responsible for detecting a hung system and might issue a reboot. According to Intel PowerTOP this option saves power by producing less wake-ups.<\/p>\n\r\nsudo update-grub\r\n<\/pre>\n
\nThe most current version as of this writing is 2.3.2. Please make sure you download the latest version here<\/a>.<\/p>\n\r\nsudo apt-get install libxrandr-dev libxtst-dev libxi-dev libhal-dev\r\ntar xvzf fjbtndrv-2.3.2.tar.gz\r\ncd fjbtndrv-2.3.2\r\n.\/configure\r\nmake\r\nsudo make install\r\n<\/pre>\n
