== Current Issues ==

'''BEWARE''': There is MediaDirect v3 stuff living on a hidden partition. Furthermore, there is also Dell Utilities partition that works together with MediaDirect and employs Vista, which is normally installed on a second partition. Ubuntu 7.04 installer did not recognize default drive layout as provided by Dell and I installed Ubuntu using "the whole drive". Recently, I accidentally pushed the MediaDirect button and it messed up the partition table. Thanks to the ''testdisk'' software I was able to recover Linux partitions and get my data. Unfortunately, I could not reproduce the problem completely, and finally I just wiped out the whole drive with ''dd'' and ''testdisk'' and reinstalled Ubuntu. After various checks I am sure that it won't happen again.

=== Notes ===

* Video resolution can be fixed by using 915Resolution application.

** Requires installation of SMP kernel

*** Requires loading restricted-modules for kernel

**** Tested with SD-card only


==== Dapper ====
After normal installation, you must install the SMP kernel to enable Core Duo processor :
{{{
sudo apt-get install linux-686-smp
}}}
restart computer, then install the intel i915GM video module (you must activate "universe" repository before) :
{{{
sudo apt-get install 915resolution
}}}
then you should have the full resolution  1280x800 .

Jemore's note :
AIXGL and Compiz works fine.
Tutorials (in french) :
http://jemore.nerim.net/wordpress/index.php?p=44
or
http://market.inattendu.org/article.php3?id_article=40

LucaManini :

Just installed Dapper from a "desktop" live/install CD.

The laptop has the 1440x900 resolution, so you need to boot in "safe
mode" otherwise X crashes on startup.

Then install linux-686-smp and 915resolution, run dpkg-reconfigure
xserver-org and reboot.  Hibernate worked out-of-the-box.

Suspend seemed to be unavailable, I edited /etc/default/acpi-support
uncommenting line ACPI_SLEEP=true as suggested on some sites with no
result. Then I opened the Preferences panel of the GnomePowerManager
(the icon with the battery) and select "Suspend" from the "Running on
AC tab" (the first one) and Suspend start working (an item appeared in
the GnomePowerManager and on the "LogOff") also just by closing the
lid.

==== Feisty  ====

Sonal :

Feisty Herd 4 : alternate CD is often suggested. i didn't try with the live-cd.

screen resolution problems until 915resolution is installed : you should force 1024x768 before you can install 915resolution.

linux-686-smp useless if use of linux-image-generic (proposed by default in my case).

restricted-modules needed for wifi. wifi refuses to switch on if switched off before standby

lid close : the screen doesn't switch off when the lid is reopened. choose an other alternative than "switch off screen" on "system/preferences/energy" (i don't know exactly the path because i have the french version

Zenith2 :

I had problems getting the 6.10 installer to work, X crashed, so I had to fix xorg.conf to a proper resolution first, before being able to boot X and then get the install rolling. Explanation found here: http://ubuntuforums.org/showpost.php?p=1710384&postcount=1

For the WLAN, I had to add the bcm43xx repository and install the bcm43xx module and then load it. Then it worked very well, except that it only runs at about 30 kb/sec. Link to instructions are here: http://ubuntuforums.org/showpost.php?p=2344658&postcount=1

Alexey Balmashnov:

Feisty: Everything tested looks to work out of the box. Except 915resolution fix, which is still required. Intel wi-fi is perfect. Basically: fast and smooth install.

==== Hardy ====

Alexey Balmashnov:

Everything tested works out of the box. Suffers from Load``Cycle``Count bug
https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695 

==== Intrepid ====

Alexey Balmashnov:

At the moment (alpha4) Desktop CD only runs with the splash disabled. Partitioner in installer looks broken to me. Installation from alternate disk went smooth, although after install had to switch off splash.

John Watts:

Broadcom wireless works fine with b43 and fwcutter. DRI is only enabled when running as superuser. Odder still, glxgears gets ~300 FPS with DRI on and ~425 FPS with DRI off.
