<p>Kotfu: </p> <hr /> <div>{{Stub}}<br /> <br /> == LCD Brightness ==<br /> <br /> This worked for my {{X61}}:<br /> <br /> Once your brightness keys work, you can set the brightness by writing to the procfs:<br /> <br /> {{cmdroot|echo 100 &gt; /proc/acpi/video/VID1/LCD0/brightness}}<br /> <br /> using a script and acpid events. However this may lead to a bug (screen flickers) described on the Debian mailing list [[http://www.mail-archive.com/debian-x@lists.debian.org/msg71942.html]]. This bug is related to the X server as it does not occur on the tty1. To fix it change your xrandr backlight control to native:<br /> <br /> {{cmduser|$xrandr --output LVDS --set BACKLIGHT_CONTROL native}}<br /> <br /> For my {{X61}}, these following scripts from [http://d.hatena.ne.jp/conceal-rs/20080309/1205083315 this japanese site] helped:<br /> <br /> % cat /etc/acpi/video_brightnessdown.sh<br /> #!/bin/sh<br /> xbacklight -dec 10%<br /> <br /> % cat /etc/acpi/video_brightnessup.sh<br /> #!/bin/sh<br /> xbacklight -inc 10%<br /> <br /> <br /> == 2.6.26 kernel ==<br /> <br /> If you are using a 2.6.26 kernel, you are supposed to use the regular ACPI backlight control instead of thinkpad-acpi, on any Lenovo (Windows Vista-capable) ThinkPad.<br /> <br /> Modify the kernel config by first disabling CONFIG_THINKPAD_ACPI_VIDEO and then enabling both CONFIG_VIDEO_OUTPUT_CONTROL and CONFIG_ACPI_VIDEO [http://www.nabble.com/T61-Brightness-keys-with-2.6.26-not-working-(NVIDIA)-td18577619.html] While you are at it, be sure to read the well-written help sections for the kernel config settings :)<br /> <br /> == Ubuntu 8.10 Intrepid Ibex ==<br /> The hardware keys work out of the box on a clean install of Ubuntu 8.10 Intrepid Ibex. No tweaking necessary.</div>

The preliminary verdict, it went pretty smooth, video settings detected properly, wired and wireless connections work, sound works. More details forthcoming as I discover them.<br /> <br /> === Known Problems ===<br /> * If you don't have an UltraBase with an optical drive, installing can be a bit of a pain<br /> * Suspending/hibernating seems quirky, I'll investigate further.<br /> * Haven't got bluetooth working yet<br /> <br /> === Installing ===<br /> The X61 does not have a built-in optical drive. That leaves you two choices for how to install, build a USB stick that you can boot from, or boot off the network. Since I already have another linux machine configured to support network boot clients, that's the option I choose. For this method, make sure you download the alternate image; I downloaded kubuntu-7.10-alternate-i386.iso.<br /> <br /> -Still need detailed instructions about how to install using PXE<br /> <br /> === Enabling the Tablet ===<br /> The wacom tablet on the X61 is detected by the installation, but disabled. You can enable it by editing your xorg.conf file.</div>
