Introduction
I recently (9/20/2002) purchased a Sony VAOI PCG-VX88 laptop. This thing is sleek, sexy looking, and very lightweight, and has all of the CPU power I need, while still having a nice long 5+ hours of battery life. It's almost completely silent. The hard drive is a small whisper, and when the fan kicks in, it's just a soft purr. About the only thing that's not to like about it is that the right-shift key is only the size of a normal letter key (common among slim vaoi notebooks). I had to reteach myself how to type some of the punctuation on the right, notably smileys. I might put a little pice of tape on there to use as a hint. Ah well, nothing's perfect. Being a linux addict, er, advocate, I quickly started trying to get linux installed. This page documents my efforts, because I've only found one other website related to linux on the VX-88.
Overall
I've gotten nearly everything to work. The install is not quite straightforward, so I would suggest that you only attempt it if you have a little bit of linux knowledge. It was made easier by the fact that the disk was already split into two partitions, but it was made harder by the fact that the dvd drive wasn't supported by my distrubition's installer. Wireless gave me a bit of trouble too, but it works now. Barring these difficulties, the rest of the installation wasn't too difficult.
As this install is more tricky than a standard linux installation anyway, I'll assume you have installed linux at least once before, and therefore, be a little less verbose about standard linux installation issues. You also need to know how to compile a kernel.
Configuration
Now comes the fun part. Be ready to get your hands dirty. It took me quite a bit of kernel compilation to get this right.
X-Windows
All that you should need to get X working is above. I didn't have any problems, it just worked.
Configure the kernel
ACPI SUPPORT! IMPORTANT!
WARNING! It's very important that you get ACPI configured and run the ACPI daemon! The bios won't support APM, I tried. As far as I understand, if you don't get acpid running, the fan won't turn on when your CPU gets hot, and it could bake itself to death, so get it running!
That said, it's time to recompile the kernel (whee!)
So, go to your favorite kernel mirror and grab the source for the newest 2.4 kernel. I used 2.4.19. I didn't use the debian sources, because I had some problems getting patches to apply. Be sure to grab the debian package kernel-package, too, it's very useful. To see how to use it, go to the Debian Website and read up on how to compiel your own kernel (it's under documentation, try the Debian Reference). Note: various debian docs say that if you compile your own kernel, it requires the cramfs patch to use the debian initrd scripts. They never mention where to get this patch. Therefore, don't use the --initrd option to make-kpkg, and be sure to compile in all of the drivers you need (ide, ext2, etc).
Now, unpack your kernel source, and then go grab the latest stable acpi patch (20020918 worked for me) from the ACPI project page. Apply the patch. Now go to the linux-ieee1394 page and grab the latest subversion snapshot. It'll be a tarball that you can unpack directly into the drivers/ieee1394 directory of your kernel source. Now you're ready to configure.
Here is my kernel .config file. Of note:
* sonypi - lets you adjust screen brightness, check battery status (doesn't work, but ACPI does), and a few other things. More importantly, it lets linux access that little scroll-wheel and button, and, horrah, lets you respond to keypresses of FN+F3 and the like. So far, it doesn't let you switch to vga mode, though 
* ACPI - enable this. You should say yes to almost every option under it, except the debug stuff, and toshiba stuff.
* IEEE1394 - enable this. You'll have to enable experimental options.
* PIIX - this is your IDE controller. Compile it in so you can boot.
* PCMCIA stuff - you should use the kernel-based card manager, yenta-socket.
* Orinoco card - referred to as "hermes", this is the wireless card.
* USB - If you want the memory stick reader to work in linux, grab memstick.patch and apply it to the kernel. It may need some finessing to get it to apply. Enable USB, and hotplugging support, and see below for configuration.
In general, you should probably just use my config as an example and tailor the kernel to your own needs. However, I take no responsibility for teaching you to compile a kernel, there are documents out there for this  Note: turn of devfs unless you'd like to configure this. I like it, but it took some tweaking, and alsa won't work if devfs is enabled but not in use.
Compile the kernel
Here's the command I used to make the kernel (run make-kpkg clean first), from in the kernel source directory:
make-kpkg --revision 2.4.19.custom.1 --append-to-version -686 kernel_image modules_image Let that go for awhile. Takes about 10 minutes on my system. Then, go up a directory and use dpkg -i to install the package. Tell it to run lilo. Reboot. Good luck.
ACPI
Check your dmesg output, be sure acpi configured everything right. It handles your cpu temperature (did I mention, enable thermal zone, along with everything else, in the kernel config?), your battery status, and also enumerates all of your IRQ's (wireless won't work without this). I wrote a little perl script to read /proc/acpi for battery status. It sits in an xterm and updates every 30 seconds. Here's the source. Note, I already had to rewrite it once going from 2.4.16 to 2.4.19, they changed the proc entries. Use at your own discretion. No support provided. It worked for me.
Wireless
This is easy. If all goes well, somewhere during bootup, the PCMCIA driver (did I mention, edit /etc/default/pcmcia and put in PCIC=yenta_socket) will detect the wireless card, and load the module. Then the hotplug daemon will notice the card and try to configure it with ifup. This will fail; go play with the scripts in /etc/network/interfaces (man interfaces, man ifup, check /usr/share/doc/ifupdown). You should use iwconfig to give it an ESSID and encryption keys (if necessary), then configure your IP address (dhcp, static, whatever). Give it a go. Check the log to make sure you didn't get an error message like "orinoco_cs.o: RequestIRQ: resource in use" (this means that ACPI isn't the newest version, or isn't loaded, or isn't working right).
As for the PCMCIA thing... it seems that, though this card is MiniPCI, it includes a little PCMCIA bridge in it. I'm not exactly sure why this is done this way, except perhaps so that the existing driver for the pcmcia card version can be used as is. Go figure. Anyway, I think that I see the pcmcia driver also detecting the real pcmcia socket... but I don't know if it actually works.
As for the wireless on/off switch... when I first saw this in the pictures at sony's site, I was thrilled. I figured, since it's a hardware switch, I'd be able to turn off wireless and save battery, from hardware. Wouldn't it be very convenient, even, if the built in pcmcia card bridge disabled the card and sent a pcmcia card-removed event? Well, it doesn't quite work this way (I don't think so anyway...). As far as I can see, it merely disconnects the antenna. WinXP figures this out and disables the interface (and then takes a correspondingly long time to figure out that you've turned it back on,  ). In linux, all you see is that your signal strength drops to 0 (run iwconfig eth1). Maybe the card is also turned off to conserve battery life, I can't tell. The little LED goes off, though, and I'm sure that saves a few microwatts ;)
Configuring that little wheel thing
JogDial is such a dumb name I absolutely hate what it does in windows; it's no help at all, and I want a scroll-wheel. Try installing the sjog package (apt-get install sjog). I love this little program. It interfaces the sonypi module to let you change brightness, and it also lets you run arbitrary commands from an easy-to-use menu. Plus, it can act as a scroll wheel (I've gotten this to work, check the web for scroll wheels and linux). I hacked the source in quite a few ways. One thing I did was to make brightness/volume adjustments more fine-grained, and another was to make the "back" button act as a second mouse button (sonypi only registers a down-click, so you only get a click, not a hold-down. Works beautifully to paste, though). Last, I made it respond to Fn-F4 and Fn-F5 to pull up the appropriate setting window, and Fn-F3 to drop the sound level to 0 (alsa automatically mutes the card). I might get my changes rolled in, but for now, email me and I'll send you the source. Now I love the jogdial... it makes a lot of things much quicker. :D Also, check here for alternative ways to use the jogdial and keys.
Sometimes, it doesn't work on startup. I'm not sure, but this seems to be the case any time when I've started the laptop cold (not rebooted into linux from XP or from linux). I have to kill sjog, remove the sonypi module, then put it back in (or let it get autoloaded) and run sjog again. What a pain. I created a boot script linked into /etc/rcS.d that just loads the module and unloads it. It's kind of hacky, but it works like a charm, and now the jogdial always works by the time I've booted.
Sound
If you have alsa installed, deinstall it. Now grab the newest packages off of http://www.alsa-project.org (driver, library, and utils, and you probably want alsaconf). Compile and install, in order: driver, library, then utils. Run alsaconf, select intel-8x0. If the test doesn't work, you may not have the right permissions set, so modify the permissions to the /dev/ entries. I used devfs; I gave up trying to figure out what devs should be there. You can too, but it'll take some work, especially for old-style /dev/mixer (which sjog uses) and sonypi (add alias /dev/sonypi sonypi to your modules.conf). Now sound should work just fine.
In retrospect, you could probably use apt-get source alsa-base (and a few other packages) to get the debian patches for it, and so you can build a debian package and install that. You have to rebuild, because there isn't an alsa modules package for kernel 2.4.19 in debian (that I know of, try unstable?)
DVD/CDRW
This is what made me really happy. It's the icing on the cake. This thing works like a charm. Go to the linux1394 page and go through their "getting started" section. In brief: insmod ohci1394, tail -f your log file, and plug in the drive (hotplugging works fine). The drive shows up as a scsi drive. I don't know where it'll be in a nondevfs system, but in devfs, it just goes into /dev/cdroms/cdrom0 (this is a symlink). Now burn away, this thing uses scsi natively. I just finished burning a cd, it works beautifully. :D
Note that if you don't use the newest snapshot of linux1394 (I used snapshot 582), your system will freeze. My system locked up until I pinged it (!). Also, it triggered numlock, confusing me to no end (try hitting numlock, and typing, pretending you didn't expect it!). Use the newest version.
USB
Oh man USB support in linux rocks. There's really not much to put in this section. I installed cups for printing, plugged in my Epson Stylus Color 860 printer via usb, and connected to http://localhost:631/, selected "usb epson printer" from the list, and bam. First try. I think the concept of true Plug and Play has finally reached Linux
To get the memory stick reader working, just pop in a memory stick and mount /dev/sda1. As far as I can tell, you can partition it how you want, and put any file system you want on there. The memory stick reader communicates internally through a secondary USB host, and works as a generic scsi hard drive. I also found that my roommate's digital camera could be connected directly via usb (rather than transferring the memory stick), and it, too, pretended to be a scsi hard drive.
In conclusion...
Everything that I want works. In fact, I'm pretty sure that this laptop is 100% supported in linux. Check the Linux-Sony page for info about linux on other sony laptops (this may help, especially info about the sonypi driver). Check the only other linux/vx88 page that I found, from which I got the idea to try the newest snapshots of acpi and ieee1394. It's rather terse, so I wrote this page. I remember how happy I was to find a similar page for my HP Pavilion N3310 laptop a few years ago, and how happy I was that I found the abovementioned page which let me get wireless and the dvd/cdrw working finally (it had been over a week, jeez! ;)). Plus, I like to give back to the linux community.
So, this ends it. I hope everything worked out for you. Email me at the address listed below, although I'm a college student, and I can't help everyone learn linux. This page is only a reference; you should know linux before you try to use this information. Also, I can't help you with debian. I just learned it myself, from all the fine documents at http://www.debian.org, so you can too. |
