I don't think that will happen. There is some hack for using the
Intel cards under Linux by wrapping some binary driver, but there's no
free driver since the Intel card uses a secret interface. I have FC3
on a Thinkpad X40 and am using a PCMCIA wifi card (Prism chip) because
of this.
Are you sure. What about <http://ipw2100.sourceforge.net/>? |

Re: fan control on evo n800v

I have a compaq evo n800v on which I want to use linux.

So I'm looking for a way to stop fan at boot time : it's active even if
the temperature is 30 degrees... if I do simple think which dont use to
many processor time (just emacs for example), the temperature never
increase and the fan is always on...
on my compaq presario 2825ea (which uses the same bios as the evo n800v) |
with Debian sarge I use a script /etc/init.d/fan-switchoff:
#!/bin/sh
#
# Switch of the cooling fan (to correct kernel ACPI flaw).
#
PATH=/bin:/usr/bin:/sbin:/usr/sbin
TZ1_TEMPERATURE=/proc/acpi/thermal_zone/TZ1/temperature
FAN_STATE=/proc/acpi/fan/C1F2/state
#FAN_STATE=/proc/acpi/fan/C1D8/state
test -r $TZ1_TEMPERATURE || exit 0
test -w $FAN_STATE || exit 0
temp=`cat $TZ1_TEMPERATURE | awk '{ print $2 }'`
if [ $temp -lt 45 ]; then
echo "Switching off cooling fan."
echo -n 0 > $FAN_STATE
echo -n 3 > $FAN_STATE
fi
exit 0
which is linked to /etc/rcS.d/S71fan-switchoff. I don't use ACPI
modules, all is compiled into the kernel. Otherwise you have to load the
"fan" and "thermal" module before running this script. Also the
directory names in /proc/acpi/fan/ may be something else.
For SuSE you place these code lines into the script /etc/init.d/boot.local.
The relevant thing are the last two echo commands.
I found a hint for this on www.moosherr.de/linux/~mooz/evo_install.html.

Any will run. I had both SuSE up to the 9.0 version and Debian testing on
a Slowshiba 300CT, which was 133MHz, with 64MB. Avoid using KDE or GNOME,
though. Launch X with no window manager and Firefox in Kiosk mode, and
you'll be fine. No real need for tiny linux distributions.

Re: Experiences with ATI's drivers: 9600 Radeon Mobility

Well I'm on the Radeon 9000 Mobility FireGL mcwhatsit or something. I have a |
IBM T40p which works a treat[1] with the open source DRI drivers under X.Org.
I get just over 2000fps whilst my CPU is clocked at 600Mhz (no ftp increase
when I knock up the CPU freq).

trying to pick the laptop based on ease of installation and 3D graphics
performance in Linux.
To be frank should this not be done on a desktop machine? Also the |
'visualisation' performance issues usually boils down to poor OpenGL writing
by the coder; as physicist/fluid mechanics guy != opengl coder usually.
The Thinkpad makes a good solid workstation, but no laptop really makes for
very good 3d acceleration when compared to desktop machines; its not what
they are really built to do although now folk think laptops are fashionable
items and want some fancy 3d card in them now :-/
| Quote: | Can anyone that does a lot of OpenGL on a Linux laptop comment on this

good luck finding a good *laptop* with that chipset. Usually they just turn |
out to be useless Dell's or Toshiba's.
When it boils down to it both ATI and Nvidia make good cards, its just ATI
could not write drivers if it was a life or death situation.  Fortunately
the opensource DRI drivers are rather good, although do not expect to play
UT2004 :)
If you have something you want me to run on my lappy at this end, send me the
source-code and dataset and I'll see how it performs.

Sounds like a BIOS bug to me. Do you have Windows installed on this
laptop? I'd be curious to see if Windows can report the battery state
accurately.
Not a BIOS bug but a ACPI DSDT bug (which is acquired from the BIOS, so kind |
of right  You can learn more about this by going to
http://acpi.sourceforge.net/ (IIRC) or sending me the output from:
# cat /prox/acpi/dsdt > DSDT.aml
I will then rewrite the relevant section for you after you install the
'acpi initrd' patch. then things should start working. On my Thinkpad T40p
I had plenty of ACPI DSDT 'bugs'. I have managed to enable fan support,
found five additional sensors, enabled C4 power saving, enable support to
change the LCD brightness through ACPI and add 'linux' support flags to the
table. You can have a lot of fun with it and make you machine much more
power saving friendly, if you have the time.

Looks like a real driver to me. The wifi wrapper is Ndiswrapper which

I see now, it downloads a binary firmware module into the card. Also,
it says the card itself has no hardware docs, so it's done by reverse
engineering. Using a pcmcia card is a nuisance, but if I want to use
an internal card, I think I'll try to find an Orinoco mini-PCI card
that's documented and doesn't need any binary downloads or reverse
engineered drivers. |

Re: Fedora or SuSE for centrino laptop? - the verdict
|
|

I went with SuSE 9.2 Pro and I love it!!! The graphical interface is
simply phenomenal and YaST makes installation and configuration so
easy. From my brief experience with SUSE, I would definately recommend it
over RedHat 9.0 or Fedora 2/3.
I did a network install and eveything went well except that SuSE didn't detect my graphics card and
monitor properties right. After a little scare and disappointment, I did
a reinstall and specified the right graphics card and monitor settings and
everything seems to be working fine. Now, I am moving on to the
infamous process of getting my wireless card to work.
Thanks everyone for the input,
BT

Fedora Core 2 supposedly doesn't detect the built-in Intel wireless cards

WiFi working. Does anyone know if that problem has been fixed in Fedora
Core 3?
I am thinking of SUSE because of its reputation and since HP has started
selling its Centrino laptops with Novell/SUSE.
Any recommendations?

The General is correct. The IPW driver is (mostly) open source - and
written primarily (so far) by Intel folks. Ndiswrapper is a Linux
wrapper for the XP driver.
Either one works fine in my somewhat limited experience with my
IBM R40 Centrino running FC2.
