Yesterday I installed DSL on Toshiba Libretto 100CT. 166Mhz Pentium MMX , 64MB RAM, no floppy, no CD. Booting from 80MB flashdisk, nice, (damn)small and quiet.

Now I am trying to find out how to reconfigure X server (Xbfdev works fine starting with 1024x768, Xvsvga does not). Libretto's screen is non-vesa 800x480. How do I change default screen resolution for the Xbfdev?

The sound wouldn't work either. Has anybody any experience of such hardware?

I can't boot the libretto from Live-CD so I have to configure and install the booting flashdisk on anaother laptop, with different hardware which doesn't exactly make the whole procedure easier.

Grateful for any suggestion...

I used to have a Libretto 70CT running DSL, that took a little fiddling to get ot work as well. Well done on the flashdisk, next time my laptop hdd dies I'll do that. As its been a while I cant remember exactly how I sorted out my laptop. If you search these forums, there should be some of my posts somewhere. Also I found doing a google search for 'libretto linux' turned up some good resources on hardware issues.

HTH! Libretto

Got DSL 2.1 working on my Libretto 100.
All is o.k. but no sound!

Tried sndconfig, installed ALSA but nothing worked for me.
Maybe some Librett user with a working sound configuration can post this here...

Like user libretto, I'm a big fan of using search engines. Using google with search arguments "libretto linux sound" yields an enormous amount of helpful info.

I can't hear you...
Being someone that wants my computer to make interesting beeps at me I wanted the sound to work on the Libretto. I haven't had much luck using the "standard" sound drivers in linux but I did find a "commercial" version of the drivers from 4Front Technologies. Folks at 4Front actually did much of the work on the orginal sound drivers and in fact there is a "freeware" version of the software with less support for different cards. Unfortunatly the freeware doesn't support the Libretto, or at least I couldn't get it to work. I didn't work too hard and just gave the folks at 4front $20 bucks and got my sound working.

I ended up installing the "Generic Yamaha OPL3-SAx (YMF715/YMF719) non-PnP" driver that came with OSS. I did have to modify the "devices.cfg" in the oss directory to match the IRQ and DMA settings for the Libretto. The following is my "devices.cfg" file...

/SECUREAUDIO OFF
/IRQEXCLUDE 3 4
/DMAEXCLUDE 2
-opl3sax #Generic Yamaha OPL3-SAx (YMF715/YMF719) non-PnP
OPL3SAX ON P530 I5 D0 d1
OPL3SAMPU ON P330 I9
OPL3 ON P388

On FreeBSD I found that the line above that describes the DMA channels would not work as shown. It would lock the computer in a horrible death. Everything was groove once I changed the line to swap the main and secondary DMA channels to:

OPL3SAX ON P530 I5 D1 d0

One other note about the sound hardware on the Libretto. Everywhere else in the world has standardized on a 3.5mm (1/8") stereo jack for smaller than 1/4" headphone connections. For some unknown reason Toshiba figured it needed to shave 1/32 of an inch more off so they installed 2.5mm (3/32") jacks in this machine. Don't bother trying to find stereo 2.5mm to 3.5mm or 1/4" adapters at Radio Shack. You need to build them. You can find the parts at Mouser. Pick up a nice metal shielded plug and a jack and wire up your own adapter.< Cited article >

How did we ever live without the Internet and search engines? :;):

The first thing I´ve did was searching the web...
There are many nice tips which I tried that didn´t work

But maybe you could tell me where there OSS directory is.
I can´t find it in my DSL installation

To paraphrase the old X-Files TV show: the answers are out there. You will have to dig a bit.

I tried another google search with the arguments "linux driver OPL3-SAx" That resulted in, among other things:

< Linux soundcard stuff >
< Linux Sound HOW-TO >
< OSS Driver Download > where I could specify the OPL3-SAx soundcard and Linux 2.4 (X86) os version

Think of it this way -- you're not likely to find anyone here who can give you a step-by-step procedure for installing sound on DSL on an 8-year old lappy. However, if you have done your resarch, gotten drivers, and are struggling with config, you'll get better help.

This article on Puppy Linux install on Libretto also discusses sound config. The answers really are out there...

Tried it again and again but still no success

Maybe a user with a L100 with sound could help me any further

I have a L100 running great with DSL, both sound & graphics work fine. At this precise time I don't have my libretto to hand so can't give details of the sound setup - it isn't as straightforward as the graphics. I'll post it here as soon as I have the time (hopefully in the next couple of days). You definitely DO NOT need to rush out & buy any drivers / software.

The graphics question is easily solved. See the WIKI (http://damnsmalllinux.org/wiki/index.php/Vga%3Dxxx) [I added the bit at the bottom of this page - hence the reference to the L100!]. To let you skip straight to step 6 of the instructions - for a L100 you need to use the cheat-code "dsl vga=808" at the boot prompt. The only other 'vital' piece of info you may want to know is that to move a window when the title bar is off the screen; position the mouse anywhere in the window then press the ALT key then left click & drag the cursor to move the window.

The L100 is great with DSL. I can listen to MP3's & browse using firefox with no interruption to the music - try that under Windows!! The battery life also seems vastly improved under DSL, I have had over 2 hours out of a battery that barely gives 45 min under W98 (even with the NOP patch for W98), also the PCMCIA cards run cooler (this may be due to the whole machine running more efficiently). Defininitely recommend DSL for the L100.

Posted by Andreas on July 07 2006,05:04

That would be great!
Up to now there are some applications I had to run under Windows because the sound card doesn´t work.
For all other things DSL is the much better choice.
I am using the extended battery and am getting 4-4.5 h runtime with my L100!

OK, to get the sound working put the following into /opt/bootlocal.sh:

modprobe ad1848 isapnp=0
modprobe opl3 io=0x388
modprobe opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=0 ymode=2 isapnp=0 multiple=0

There may be a problem with accessing all of the volume controls if you are using an older version of DSL (about 2.2 or 2.3). John altered DMIX recently to cope with systems such as the L100 which use 2 separate mixer devices. In DMIX you should see a total of 13 channels which you can control. If you don't you won't be able to contol the master volume, bass, treble, momo mic (the built in one), or digital input (not sure what this is, but it's listed as a channel if you do 'umix -q' in a terminal window). I'm still running DSL2.4 so I can't comment on any problems with DSL beyond that release - just laziness that I haven't upgraded.

If you have any problems with the graphics or sound settings I've suggested let me know & I'll double check my system.

Andrew.

EDIT...... Just noticed you are running DSL2.1. If you don't want to upgrade I have a modified version of DMIX which will allow access to all the L100 sound channels. I've also sorted things so sound settings are reloaded after a reboot. John found a problem with my version of DMIX if too many volume adjustments were made in that it crashed with a segmentation fault. No obvoius reason why it should. I have repeated the fault, but only under severe use of the volume control. Under normal use it seems to be OK. Even when it does crash it restarts OK from the button in the dock.

EDIT #2......

Having checked my setup again you don't need the first line (modprobe ad1848 isapnp=0). I think I'd put that in while testing things & hadn't checked whether it was really necessary, it gets loaded with the opl3 module anyway.

Also DSL 2.4 has the version of DMIX which John updated to cope with systems such as the L100 with 2 mixer devices in use. If you update to at least 2.4 you should have no problems.

Thanks VERY MUCH for the suggestion of vga=808. I had been running with fb800x600, so the bottom of the display was unviewable. This fixes it.

Here's a suggestion in exchange: I modified .fluxbox/keys to incude

Mod1 F5 :MaximizeWindow
Mod1 F6 :Close
Mod1 F7 :MaximizeVertical
Mod1 F8 :MaximizeHorizontal

These commands fit the active window to the 800x480 screen so you don't have to move it around. Fluxbox docs include a number of commands to let you resize windows by numeric parameters, but I couldn't get those to work.

I agree: DSL is a great fit for the Libretto. My p166 and 64mb ram are faster than Suse 10.1 on my "modern" laptop. (But even with DSL the keyboard on the Libretto is still tiny.)

Hi andrewb,

did an upgrade to dsl 3.0 and configured bootlocal.sh as you´ve told me... bingo

Now my lib100 is better than before...
Thanks a lot

Andreas
