Linux on a Fujitsu U810 - External Monitor

external monitor

External resolution goes up to 1920x1600, which is better than the external resolution achieved under windows using the original fujitsu video driver.

As of 2009.03.31, video driver intel (xserver-xorg-video-intel) provided by ubuntu jaunty release does not include a patch that makes external monitor to function as expected. This problem was not present on ubuntu 8.04, so you might prefer to stay with 8.04 until ubuntu includes that fix.

update - 2009.05.06: please see this other post, since there's a way to obtain the package with the patch included!

The bug is: https://bugs.freedesktop.org/show_bug.cgi?id=17823

and the patch is already submitted:

2009-03-05 SDVO: handle multifunction encoder (try 2) Zhenyu Wang 1 -65/+160

If you want to have external monitor working you must apply the patch by yourself; otherwise, wait until ubuntu maintainers include the patch in the official release.

See this other post about notes how to apply the patch yourself.

Update (2009.04.15): See this other post about how to install a patched driver or install the patch yourself.

I'm monitoring when the patch is included, and I'll update this page accordingly; analyzing current patch speed, I expect this patch to be included by 2009.04.20.

external monitor switch hack

Since the Fn+A button doesn't work as expected to activate external monitor, I suggest to take advantage of the brightness-up button (Fn+D) to have the computer switch between the LCD and the external monitor.

In order to do so, as root edit the file /etc/acpi/video_brightnessup.sh to look as follows:



test -f /usr/share/acpi-support/key-constants || exit 0

. /usr/share/acpi-support/key-constants
acpi_fakekey $KEY_BRIGHTNESSUP

logger "auto screen selection"
X_USER=$(w -h -s | grep ":[0-9]\W" | head -1 | awk '{print $1}')
export DISPLAY=:0.0
export XAUTHORITY=/home/$X_USER/.Xauthority
if [ -e /tmp/xrandr.auto ]
logger "activating lvds"
rm -rf /tmp/xrandr.auto
/usr/bin/xrandr --output VGA-1 --off >> /tmp/xrandr.auto.log 2>&1
sleep 1
/usr/bin/xrandr --output LVDS --auto >> /tmp/xrandr.auto.log 2>&1
logger "activating external"
touch /tmp/xrandr.auto
/usr/bin/xrandr --output LVDS --off >> /tmp/xrandr.auto.log 2>&1
sleep 1
/usr/bin/xrandr --output VGA-1 --auto >> /tmp/xrandr.auto.log 2>&1

With this hack, external monitor switch always works either the external monitor is connected or not. If you want to bring screen brightness up without switching the screen, just use the brightness control provided by ubuntu.

other hints

- if you cannot get past 1024x1024 resolution on the external display, with the updated driver, verify that int he /etc/X11/xorg.conf file there's a line like
SubSection "Display"
Virtual 2048 2048

- this is my /etc/X11/xorg.cong
Section "Device"
Identifier "Configured Video Device"
Option "SDVOBOutput" "VGA-1"

Section "Monitor"
Identifier "Configured Monitor"

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"

SubSection "Display"
Virtual 2048 2048

- commands to add a mode for a display

mode definition
xrandr --newmode "1920x1200@60" parameters

mode assignment
xrandr --output VGA-1 --addmode "1920x1200@60"

mode activation
xrandr --output VGA-1 --mode "1920x1200@60"

=> things to watch

- watch when ubuntu has the proper patch applied to xserver-xorg-video-intel (expected: sometime in 2009.04)

- watch when ubuntu properly detects the FN+A key to activate/deactivate external monitor (need to test as new ubuntu releases happen)
