This should be a fun toy when it shows up. I ordered a T42p today with the 15" 1600x1200 screen and a Dothan 1.8GHz CPU. Kept the RAM and HD low and will just add more later. Crucial doesn't list it yet, but I figure it uses DDR PC2700 non-parity RAM just like the T41p. Now to find a decent 80G 7200 rpm notebook drive to toss in it.
I did consider a Powerbook for a while, but I am too used to Linux and I really am more comfortable on a Thinkpad. One of the big draws of the Powerbook was the DVI-out on it, but with the Thinkpad mini-dock which is only $89, you get that anyway, and it's not like I will be tossing my 20" LCD into my backpack and bringing it with me, so the dock can just live permanently by the LCD for a very nice dual-headed workstation when I am working from home.
By the way, ordering this thing was amazingly painful. The ordering web site is/was completely messed up and there was no way to click your way to it. Had to call and have a human do it for me. If you are looking for one, I would suggest finding someone who works at IBM who will let you use their friends+family EPP discount and go in via www.ibm.com/shop/epp or if you own some IBM stock you can use the Shareholder Purchase Program at www.ibm.com/shop/us/spp to get a couple of hundred dollars off your price.
June 23rd Update: It finally arrived! Of course I am out of town so I can't play with it yet. Frustrating.
July 5th Update: Finally back in the country and have started playing with this beast. It's the same thickness as my old T20, about an inch wider and a bit over half and inch taller. But that Flexview display is amazing. And no, 1600x1200 looks just fine on it. I never really understood the argument that a display could be too small for a high resolution. Just set your font size to your liking. The higher resolution means your anti-aliased fonts have that much more definition to them making them clearer and easier to read which is exactly what you need on a "small" display.
I am waiting on another 512M of RAM and a speedy 7200 RPM 7K60 drive to install Debian on. I'll keep the 5K80 that came with it as a secondary XP drive that I can pop in the Ultrabay the one or two times a year I actually use Windows.
July 10 Update: Debian has gone onto this thing. It installed pretty
smoothly. I always use this 31M XFS boot
for installing Debian these days. To do a network install just remember
to specify "e1000" when you get to the part that asks you which extra
drivers to load. Here is my .config in
case you are curious. I ended up using ATI's drivers for the FireGL T2
(basically a Radeon 9600 card) that is in it. There are also open source
which work nicely, but the 3D acceleration wasn't very good.
If you follow these excellent instructions it is easy to get the ATI drivers going, and you will have very fast accelerated 3D. Make sure you build your own modules instead of trying the precompiled ones he lists. I had a world of problems with those, but as soon as I built my own against my 2.6.7 kernel everything started working. I used the "fglrxconfig" program to generate my XF86Config-4 file for just single-headed 1600x1200 for now. Need to play more with the port replicator and dual-headed stuff and also come up with a way to reliably connect to 1024x768 projectors. I am getting around 1785FPS from glxgears and 380FPS from fgl_glxgears (default window sizes). Offscreen fgl_glxgears runs at 1125FPS.
Sound works fine with the snd_intel8x0 driver, and the built-in a/b/g wireless works nicely with the madwifi driver. I use apt-get to grab it via this entry in my /etc/apt/sources.list file:
Someone in the comments mentioned problems with pcmcia stuff, but I
haven't seen any issues. Anything I plug in comes up right away.
Dual-booting to WinXP sitting on the original drive in the ultrabay worked on the first try. I added this to my /boot/grub/menu.lst file:
The big thing I still need to work more on is ACPI and getting it to suspend and wake back up. It suspends perfectly right now, but it just won't come back out of suspend which makes the fact that it can suspend much less interesting.
Another interesting problem I hit was that if I used the Radeon Framebuffer to get a cool-looking console then the fglrx ATI driver would crash the system on switching between X and the console. If I don't use the framebuffer for the console everything is fine. Haven't tracked down a solution to this one. For now I just use the vesa framebuffer for the console which works well.
July 17 Update: I spend half my life on planes and the other half presenting. I haven't found any way to make the former easier on me as I absolutely hate flying, but for the latter I trawled the Net and came up with an idea by Klaus Weidner for running a vncserver and then a viewer onto that server session both on the local lcd and on the external vga port. That means that now when I present I can have the contents of the projector in a window on my desktop. This will be very nice, especially for my duller talks as I can read email or irc while presenting without people seeing that.
First, here is my XF86Config-4 file. Note the dual fglrx device sections and the dual screen sections and finally the single and dual ServerLayout sections. Unfortunately X is quite unhappy starting up with the dual layout if nothing is connected, but you can check that with a tpctl call. I use this little startx wrapper script:
So I just need to restart X to have it automatically figure out if the second display should be enabled or not. Next, to run vncserver and the viewers along with a window manager (metacity) and a panel I use this script:
As far as my suspend problems go. The problem is the ATI fglrx driver. I would have to switch back to the radeon driver but then I would lose tv-out and some 3d-performance. Probably not a bad tradeoff actually.
