You will get almost as many different answers as responses
to this question. Frankly, given the way things are i'm not
sure it is safe to recommend any brand per se. For a given
brand the hardware will be different in each model and may
even differ between production runs of the same model.
I've been happy with my Sony Vaio F160 but some people have
reported problems with the F series. Most major brands have
at least one model that has caused problems. Dell and
Compaq are notorious and yet there are many people have
gotten them to work.
The best thing i can recommend is to go to
http://www.linux-on-laptops.com/, Read the HOWTOs, and
finally find some models you like and check to see how
others have fared with them.
Alternatively you could buy a laptop with linux already
installed. Unfortunately that is often more expensive than
buying one with MS-flavor-of-the-month installed and
reformatting.

Not the cheapest, but certainly one of the best is the IBM Thinkpad
I've got an A20p, A21p and A31p and have got all hardware on those
models working nicely; ACPI/Power management being the only problem
area, although I'm happy with my setup.
And if you want a good used a21p, let me know ;)

I agree, I buy them exclusively for people in my company, I think I
have around 10 of them.

I like the T23 myself. Wireless, ethernet, modem, DVD, fast.

Serial modem, or some winmodem type? I'd prefer to have a "real" modem,
though...

Winmodem. I'm pretty sure I got it to work under Linux at some point but
I'll admit that I boot into windows on those rare occasions I need a modem.
Getting that stuff to work under Linux is fragile at best.

Don't know if it's the same modem or not but there is a driver for the
winmodem in my 600E distributed by IBM at the following link:
http://www-124.ibm.com/acpmodem/
Hope this helps.

There's a driver at http://www.physcip.uni-stuttgart.de/heby/ltmodem/
It's worked quite well for me.. (with T21) The only real trouble with it
is that it's largely binary only :(
Another caveat with T2x'es is that there are two kinds of them: for the
seemingly more common variant the ltmodem driver works, for the other
MiniPCI modem no driver exists.

Well, that starts being a KO criterium. I'd like to see a laptop like
this:
- one or two serial interfaces
- modem
- IrDA
- TFT display, with a nice graphics chipset (I'd like to have
ATI, but with a good, free driver, and it's own RAM, no UMA
stuff...)
- Large HDD
- Good akku, best with possibility to plug an external extra
akku onto it
- PC like keyboard layout (with the 6 keys above the cursur keys
kept togeather, not as a row on the keyboard's right side or
so...). I don't need those Windows(R) extra keys, neither do I
need extra "email", "web" ot the like keys...
- CPU (i386, ppc, ...) doesn't really matter, but of course I'd
like to see Linux support:-)
- network interface (100MBit/sec is okay, GBE is nice, too:-)
- Floppy
- CDROM, maybe DVD or CD-RW or sth like that, but that's IMHO
not that important.
- parport
- VGA out (I personally don't need TV in/out)
- USB? Well, I don't need it:-) I don't like it...
- Firewire. Yeah:-)
Anyone?
MfG, JBG

And if you want it for what a portable is, get the 12" one, just a bit
bigger than a calculator ;). I would kill for one of those...
And obviusly go to LinuxPPC...

FWIW I prefer Apple notebooks, not only because they feature all of
these but are also cheaper, not so heavy and last much longer on
battery. And one gets easily addicted to the look and the nifty features
(like Gigabit ethernet, size, screen dimensions, keyboard, DVI, DVD
burner [in no particular order]). The current models (modulo the newly
introduced ones two weeks ago) are working nicely including a real
powersafe mode; the new PowerBooks will probably cause troubles because
of the $§"%§%$ NVidia GPU....
I do have a PowerBook G4 500 and a brandnew iBook 800, the former now
lasting longer than any other notebook I've ever had (Compaq, Toshiba,
IBM).

I dual-boot the COMPAQ Presario 1800. I have had zero problems with
it under Linux-2.4.18 and very few problems under Win/2000/Prof.
It's not a great performer, it uses the same interrupt for about
everything and has a slow disk. I have an ACOM external USB/Firewire
drive that works fine as well.
Cheers,

I have a G4 667 powerbook titanium III and the battery life is very poor
(around 2hrs) it gets very hot, I think its a kernel problem. Which
kernel do you use, could you send me your config off list perhaps?

I'm using 2.4.x and 2.5.x kernels; no special version.
A few pointers:
You might want to check /proc/sys/kernel/powersave-nap is "1".
Any suspicious messages on bootlog? (Post if in doubt)
What CPU does it have (post /proc/cpuinfo).
What clocks does it support according to /proc/cpufreq?
What does the pmu say? (see /proc/pmu)
What does the APM emulation say (need to run pmud to get reliable
results)?
Are the infos from the battery accurate? I need to completely empty
the battery without pmud every now and then to make the infos realistic.
Normally Motorola cpus turn of unused units to save power,
you might want to check that your system is really idle;
when running setiathome for instance my notebook also gets
warm and the battery is draining much faster (intersting
fact actually, since common belief is that the current drawn
by processor is far less that the sum of all other components).

Well, the common belief is wrong. Wrong on
notebooks (130 vs 75 min for omnibook xe3),
wrong or zaurus (if you can live without frontlight

I appear to get nothing like this, if i pull my power out with a full
battery the PMU says I have 152 mins of battery power (which seems about
right). I even ran the battery completely flat and recharged it as
suggested when I first got the laptop.
The whole of the laptop is warm, esp. around the CPU which is hot to the
touch all the time, even when the CPU is idling.

2.4.20-benh1 doesn't know about this version of the cpu.

Strange. Either the kernel couldn't find the allowed frequencies for
scaling or the cpu doesn't support it.

152 is nothing....

This is not normal. Since the kernel doesn't know either the usable
frequencies, your version of the cpu and no doze mode is available
for this type, your energy savings are almost nil at the moment and this
should definitely be rectified. I cannot imagine Apple built a CPU into
a PowerBook which doesn't support some kind of throttling, because it
would kill their statement under their OS, too.
Unfortunately I'll have a whole bunch of nasty tests the following week
and thus cannot check back with the manuals at the moment; feel free to
send me a reminder in a week or so.

OK, well just for your info, I added an entry in the cputable for
rev2.1, identical flags to the 2.0 entry and nothing has changed. Still
no cpufreq data, case is still warm all over. I put debug messages in to
my pmac_cpufreq.c and I get the following:
HID1, before: 80016c0
HID1, after: 16080

Cool will do! I'd be very interested to see any ppc/powermac manuals you
may have. I've not been able to find much myself (just instruction
reference and stuff from motorola). If you could send me URLs that would
great.

I just bought a Sony Vaio GRV550. So far I have not had any real
problems with it. There was an issue with sound in 2.4, but fixed in
2.5. Talking with some people, we came to the conclusion it was just a
bad merge, and no problem with the hardware being supported. The Radeon
card works great in X11, although has issues with the framebuffer in
2.5. PCMCIA works great, currently have 802.11b working. DVD/CD-RW drive
works great. Pretty much everything else is detected and supported,
although I have not tried to get the built in 56k modem working. The
screen is big (16.1"), and at 2.4ghz it is rough on battery (about an
hour and a half for a full batter).
Other than the frame buffer in 2.5 and sound in 2.4, it works great.

Matthew J. Fanto

I have an Evo 1015v, which is a bit of a pain to get working.
You need a very recent kernel just to be able to boot the thing, or
it'll lock up during hardware detection. Installer kernels typically
need to be booted with 'nomce', or probing causes a machine check.
The ATi Xserver locks up with a pretty display of garbage, (use
the vesa driver). Sound is currently not working afaik.
Power management: ACPI worked on it. Up until recently. Latest
2.5 seems to lock up very early in the boot.
Native Athlon Powernow support for cpufreq I'm working on, and am
making progress. IDE is a bit hit and miss. It works, but it's
no screamer in the performance dept. (Likely because no-one has
the relevant info from ATi on their south bridge).
AGP support is also lacking due to missing docs. DRI support
for that onboard Radeon mobility is afaik also missing.
Vesafb works.
So.. it's not that bad when you know the pitfalls, and it gets a good
3hrs or so on battery. (Which is pretty good for a 1300MHz CPU & large
display).
The key to why this one was such a pain was very likely the
"Designed for Windows XP" logo stuck to it.

I'm writing this in Compaq Presario 900Z which seems to be similar to your Evo
1015v. After installing RedHat 7.3 with nomce, nopci, etc. I've disabled kudzu and
then compiled 2.4.20+ac2+acpi-20021212-2.4.20 with sound and IDE fixes. Now I have
UDMA IDE, sound, and 802.11b with prism card (actually I'm writing this at home on
remotely running Netscape in my office over X11/ssh/ADSL/wireless home FW8-604
router;). The only option left for kernel is ide-scsi, the rest is done by the
kernel automatically.
ACPI patch with acpid and aKpi provide correct information about battery status.
Did not try any goodies like suspend and hibernate yet.
The only problem is ATI IGP320M graphics. I can use only VESA X driver but it works
fast enough even in 32bpp with 1400x1050 resolution.
In conclusion, I'm quite happy with this notebook: some trouble with installation
but overall impression is very good.

What IDE controller is in the 900z? I have a fujitsu notebook with the

Have you applied sound fix? This is what I did:
1. Got stock 2.4.20 kernel;
2. Applied ac2 patch;
3. Applied ALI sound patch (discussed here recently);
4. Applied acpi-20021212 patch (some manual work needed after previous patches);
5. Reenabled IDE UDMA (ALI IDE support which was disabled in ac2 patch);
Then I've copied RedHat's 7.3 updated
/usr/src/linux-2.4.18-18.7.x/configs/kernel-2.4.18-athlon.config to .config in the new
kernel directory and run 'make oldconfig' enabling new ACPI.
After kernel compilation and installation I have almost all features enabled.

Its an ALI 1535 southbridge with built in IDE DMA support. The 900Z basically
requires you run 2.4.21pre3-ac5, probably the ACPI patches on top of that
and also pcmcia excludes correctly configured to avoid 0x380-0x3ff
In paticular you can boot with "nomce" but if you do that and don't deal with
the real problems may get some nasty suprises

I just recently purchased one of the 5600 series, and have
had no issues with it. You don't have to pay the Microsoft
tax, and it mostly just plain worked out of the box. The
only challenges were finding drivers for the softmodem (which
works fine once I got the drivers) so that I don't have
to occupy the single PCMCIA slot with a modem, and getting
accelerated X - I'm using closed source drivers from ATI
for the Radeon 9000 chipset, at least until the Radeon
work in the kernel (and in XFree86) catches up. X worked
fine with just the default vesa driver for most purposes,
but DVD playback and other video intensive things was
far from ideal. The only thing I would have even changed
in the design of the box is to put at least one external
serial port on, because I use it frequently as a terminal,
but I got a USB to serial adapter for $20 that fixed that
quite readily...

You might consider other archs as ppc for example, especially
if you really don't care about windows OS and you want more power
saving on battery.

Linux is still too obscure for a good certification list. (Have
heart, the internet was once obscure too...)
> Would you recomend me any brand of computer ?
Download the Knoppix CD (knoppix.com). It is a bootable Linux that
runs from CD and is quite usable. It is based on Debian. Bring the
to your local omputer store and try booting different models with the
CD and see which ones work. That will give you one data point on how
Linux compatible the computer it.
> - - sound is hard or impossible to setup correctly.
I have an MSI motherboard-based computer at home on which Red Hat
couldn't make the sound work until 8.0--but the Knoppix CD has managed
sound on that machine just fine.
Knoppix is also a *great* rescue CD--and a nice way to temporarily
turn a groady MS Windows into a decent Linux machine.
> Any help/advice would be apreciated.
Laptops are just like big office computers, except they are more
expensive, less compatible, less powerful, easier to steal and fence,
and smaller. Um, clearly "smaller" is the feature here. Unless you
really expect to only use it on two different desks and move it
seldomly between them, I say go for small. There is a world of
difference between a computer that weighs under 2 kg and one that is
over 3.5 kg. Go for small and you can bring it with you on spec.
Given builtin ethernet and wireless, the need for floppies or CDs is
much less. I have an old Sony Z505LE with no CD drive at all. I have
done Linux installs with an external USB floppy and an NFS copy of the
distribution. I have no regrets that I didn't spent $300 extra for
Sony's CD.
Also battery life is important. And what do extra batteries cost? My
original "single capacity" battery is worn out. It can keep my
computer in suspension while I commute, but can't really use it. And
replacements are really expensive. I wish the Apple Ibook were x86...
-kb, the Kent whose current evening project is to remaster Knoppix
with tripwire added and use that plus a locked floppy as a trustworthy
intrusion detector.

Look for a webpage of someone with the laptop you like.
I have a Dell Latitude C600, and found a webpage with
kernel config, and in detail description for every component
and how to get it working / whether it is possible.
I had problems with:
- acpi (too old / bios no longer updated, but APM might work fine)
- winmodem (ibm has drivers, dell has not AFAIK)
- grafik: advanced features like using tv-out and stuff. to be honest
i found no good docs on that at all, neither generic nor specific.
- the maestro3 driver caused a problem in the irda driver.
everyone else: please write such webpages, they realy help!
Regards, Andreas
