[LUG] A couple of problems with my lappy...

 

Hi all.

Since we've a semi-topic about laptops on at the moment, I thought I'd throw my 
small problem in the hat.

I have inherited a reasonable laptop.  It's a Mendocino Celly @ 300MHz, 256Mb RAM, 
20Gb HDD.  It functions perfectly, albeit it runs slightly slower than that to which 
I have become accustomed on my desktop machine.  However, speed is not the issue 
here - afterall, I only really use it for classes at College... more on that later.

First thing first, though.  The system comes with an ESS1869 sound controller.  Try 
as I might, I can't get this thing to work without it causing a complete kernel 
freeze at some point or other (usually if I try using mplayer with it).  I can't get 
the ESS module(s) to work at all, and the SB module is the only things that works... 
but then causes the freeze.  It's picked up nicely with *lspnp* but isn't listed 
with *pnpdump* (infact, nothing is listed with pnpdump).  Anyone got any ideas?

Secondly.  College use a lot of "interactive whiteboards" (Promethean ActivBoard).  
Hence, I use them a fair bit.  The room in which I take most of my classes (if not 
all) has the VGA splitter in the far corner of the room.  This makes it really quite 
hard to have a smooth-running class... having to keep going back to the laptop in 
order to move something that's projected onto the board.  It would be really nice if 
I got use the IWB as it should be used.  Obviously the placement of the PC to which 
the IWB is normally connected isn't a problem... guess which system that runs on?

Now, the IWB connects to the PC using a standard serial connection (9pin).  I have 
tried connecting to both the serial port on the laptop and to a USB->Serial adaptor 
I bought (originally purchased to facilitate easy access to the routers in the 
labs), and I have tried all of the driver/protocol combinations that I could find 
for serial "mice" under X.  All to no avail.

Finally getting to my point: has anyone had any experience with these IWBs?  Any 
thoughts on how I might be able to get it to work?  I've been onto Promethean about 
it, and have a guess what the response I got was!  Surprisingly it wasn't "sod off, 
we don't support Linux", but the guy thought that I might like to consider using VNC 
to project the Linux session but use Windows for interactivity.  I don't.

Cheers all.

Grant.
