Right, I've taken out the cmode part and it still works as before. Now I *am* confused! I thought the video=... stuff was nothing to do with X, but it started to work when I put it in!

I found out that on this G4, append video=atyfb:vmode=22:cmode=24 works wonders. Then the DefaultFbBpp line in the XF86Config-4 file is unnecessary (in fact, has to be removed).Color depth in console and X are independent. In fact, anything besides cmode=8 is a waste of video RAM and performance for console because it only has 16 colors anyway.
Anyway, thanks to Liam, the keyboard problem's also solved. I ended up adding the following to /etc/X11/xkb/symbols/macintosh/gb
key <LWIN> { [ Mode_switch ] };
Now apple-3 produces the # sign (look!! --> # <-- little things please
little minds!) as advertised. I also have to get the tilde/grave key to
produce tilde/grave (it produces < or > in the console, and the
plus/minus / section key -- top left of the keyboard -- does the
tilde/grave thing) It took ages to find this out: the key is inbetween
the left hand shift key and the Z, so I don't understand why X thinks
it's AC11. It returns kecode 94 according the xev: this is strange
because that's the code for KP4 according to the keycodes file I looked
in. I don't know what's going on here, but this fixes it (and changing
KP4 stops the 4 on the keypad from working, so at least that's consistent).
key <AC11> { [ grave, asciitilde ] };
Tried the ati driver instread of the fbdev one. Much faster, still nothing much to write home about, but entirely acceptable now. I guess I am spoilt by the other machines in the lab (we try to use Tyan Thunders with 1GB RAM, a 37GB SCSI disk, and two 1.4GHz Athlons as our standard machine, which costs less than a G4 in the UK, incidentally. There is Rage128 on the motherboard (and two 100Mb ethernet ports, and two SCSI controllers, and... but I digress ;) )The result is a very beautiful display, but it's very, very slow. I expect you knew that. However, since most of my programming class seem to spend their time gazing at the utter beauty of C source code, I'll go with it for now ;)Are you using the ati driver? It should give fairly decent performance.
I still don't know where the list of vmodes is. In the end, tralling the web at random chose 22 for me. I thought it might be in the XFree.org site, but not where I can see it. I suppose it's apple-hardware specific, but I can't find it in their documentation (which is not much fun to read for a Linux geek).It certainly doesn't have anything to do with XFree86. ;)
Right !Thanks, everybody, for all the help. (I'm going to write a macro to type that for me at a single keystroke :)
