So I downloaded and installed Ubuntu to dual-boot on my G4. I've had it there for a couple months, but it's so slow that I don't like using it--I do like apt-get, though.

Anyway, I downloaded the Gentoo install disk and the manual and got to work installing. I used the same partitions where Ubuntu used to be. Installation wasn't automatic like Ubuntu, but it wasn't hard either. Now I have gentoo and my desktop (gnome) set up and this is _way_ better than Ubuntu. It took about a week to get this far--long compiles--but I'm much happier. This is great.

Now, I'm sbviously new to gentoo, but I'm also quite new to Linux in general. My co-worker uses it at home, I have typically used Mac OS X; we use Windows at work because we have to. I like Mac OS X and don't plan to completely forsake it, but I'd like to more-and-more work in Linux because I write software as a hobby and I'd like to have two operating systems to cross-develop for on my machine. To get to the point, I have a few questions as a new user and SORRY if they're obvious or answered elsewhere:

1. My sound doesn't work. Trying to 'test' from the System > Preferences > Sound results in "audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open resource for writing." Did I miss some options while compiling the kernel or is there something else I need to set up?

2. If there's a way to enable the sound/cd eject keys on my Apple-branded keyboard, that would be way cool. Otherwise, I don't see how I can open my cd-rom drive, which is a bummer.

3. My desktop is incredibly faster than it was while using Ubuntu, but I'm not sure if it has 3d optimized because (unlike OS X) there's not a whole lot of eye-candy things going on in gnome so I would expect it to be fast anyway. I emerged '3ddesktop' and that seems to work fine. I'd like to try beryl or something similar, but it's flagged as unstable so I'm hesitant. Any thoughts? (I do have a radeon.)

4. How should I find and install software? It's easy in OS X... Just download it directly from a website and drag it to Applications, but what is the appropriate process here? I can use Portage to emerge the popular stuff that I know I need like openoffice, eclipse, gaim, firefox, perl, etc. but how do I get/try software that I'm not aware of? For example, in OS X I use iTunes to listen to my music. The default installation of gnome didn't give me anything to listen to music (even if my sound did work) and being newbish I don't know what to get that will be similar to iTunes.

5. I've become rather dependent on the functionality of Expose in Mac OS X. I need to be able to see the desktop by a keystroke and also have windows arrayed for choosing by a keystroke. How can this be accomplished? I don't really like the taskbar at the bottom that displays all the windows, and it would be quite unnecessary if I could array my windows. I'd much rather have just an application launcher (perhaps like the Dock) instead, but maybe this is only a gripe I have with gnome...

Well that's all for now.

Thanks,
onefriedrice

You may want to look into Mac-on-Linux, which is a program for virtualizing Mac OS X inside Linux on PowerPC.

1. Make sure you read the PowerPC FAQ and the Gentoo Alsa guide and follow the directions in there with respect to sound. If after consulting those two you still have trouble, post in here again or drop by in #gentoo-ppc in IRC (freenode.net)

2. What sort of G4 do you have? I know that pbbuttonsd enables those features for laptops, and I presume it could for desktops as well, but I do not know the answer to that.

3. In my experience Beryl with a Radeon on a G4 can be a bit sluggish depending on which features of beryl you opt to use. It is doable (I've done so on my iBook G4), I believe there is a Beryl howto over at gentoo-wiki.

4. Specifically you may want to try out Amarok as something similar to iTunes. Generally you can search at gentoo-portage.com or packages.gentoo.org (currently down due to a security issue - should be back soon) for keywords. Also, you can Google for free software software packages, or use Wikipedia which has plenty of lists of various kinds of free software. Odds are that Gentoo will have most of the important stuff in portage already.

5. Beryl has an expose-like function.

EDIT: If you are interested in a more Mac OS X-like desktop environment you should keep an eye on the Etoile project, which is currently in early development. It is based on the same API as OS X (Open Step) and has the same dock/menu bar paradigm.

1. I recompiled the kernel with some different options. I have yet to reboot to test it because OO.org is taking a very long time to compile. We'll see if that helps the lack-of-sound problem. I don't suppose there is a safe way to stop an emerge and start again after rebooting?

2. It's a Quicksilver G4 (800MP). The keys did work in Ubuntu so I'll have to find out what they're using.

3. I'm not really into the wobbly windows and all that other eye-candy stuff, so hopefully I can use it only for the Expose functionality with reasonable performance.

Thanks for your comments. Here's another one:

System Monitor says I'm using whatever of 754.8MiB, which is actually half of the total memory I have installed (1.5GiB) so it looks to me like perhaps gentoo is not finding/using all the memory. Is this really the case and how do I fix it?

Thanks,

Hello and welcome to gentoo on ppc. I also have a G4 with similar speed.
OO.o usually take about 25 hours when I am not doing anything with the machine :( ....
No way to break the compile and resume at the break point. There is a feature of
portage that may help you not completely restarting from scratch but it is a bit more
advanced.

Before you go into the whole compiz stuff what graphic card do you have? If you
have a nvidia like me you are out in the cold for accelerated 3D graphics as the binary
drivers needed for those are only available on x86. If the quicksilver is a laptop it should
be a radeon card which should work OK with free driver.

To open and close the cd tray. I haven't mapped my keys to anything but it is possible.
Otherwise on the command line you can type "eject -T" (the -T will do the appropriate thing
depending on the case where your tray is open or closed) I made a nice button on my desktop
panel in kde so I don't have to type it.

For your memory problem you will need to have another look at your kernel to enable the
use of more memory otherwise you won't be able to use your 1.5 GB.
Under "processor type and feature" select "High memory support" and select "4GB".
If you still don't see all the memory post again there is a standard way of telling the kernel
the amount of memory available but you shouldn't need to.

Hey thanks.

The Quicksilver is a desktop. It originally came with a geforce 4 mx card, but I've since upgraded to a Radeon 9800. I've got sound working. I'll look at the kernel options again to see if I can fix the memory issue. As for OO.o, the partition I'm using to store portage/system files eventually ran out of space and so emerge failed. Oops. :oops: Guess I should have made it bigger before installing gentoo. Oh well... I don't need OO.o all that much. All I need is a simple word processor for a few things.

Anyway, thanks for the eject tip. Now I've got an eject 'launcher' in gnome. I'll still need to eventually figure out the media keys.

Ciao,
onefriedrice

OO.o is probably the biggest thing I have ever emerged and I am not sure
there is anything bigger in the tree. You need between 4 and 6 GB of disk
space according to the instructions. I found that 5 was usually alright.

Okay cool: pbbuttonsd does work for desktops to implement the media keys. Thanks ndansmith.

I fixed the memory thing. For future reference to anyone else, the kernel option (at least for the PPC menuconfig) is called "High memory support," but it is actually under "Kernel options." It took me forever to find it.

Also, there is no need for pbbuttonsd. Gnome's "Keyboard Shortcuts" is able to set shortcuts to the media keys even though it doesn't recognize them. That works a lot better without having to run a daemon. I love this...

But I am now having a problem now not being able to login (to desktop) very well because it appears like not everything is loading, giving me an unusable desktop. I posted it to the desktop forum thinking that would be more appropriate, but for more details and if you think you know what's wrong: https://forums.gentoo.org/viewtopic-t-578816.html

Thanks,

Really??????
I am not at my ppc machine right now, on my x86 machine it is where I said it was and I
could not see and I cannot find such a thing as kernel options when I do "make menuconfig".
