I've been running Debian Sarge on an iMac DV G3/400 for about a month now, mostly with no complaints. However there are a couple small annoyances that keep me from loving it completely. Who can help me out with one or more of the following issues?
The first issue is with sound. The iMac has 4 audio outputs: 2 headphone jacks, 1 line out connection, and the built-in speakers. The mixer in Debian identifies line-out as the master control and provides no level adjustment for the two headphone outputs; the built-in speakers are identified as "PC speaker."
Here is my problem.
Since I primarily use the built-in speakers with this machine I constantly have to open up Kmix, or another mixer (alsamixer, gmix, etc) to adjust the PC speaker volume, instead of just being able to use the Kmix dock applet and adjust the master volume. This also makes it difficult to do something like assign keys to control the volume. What I want is to make the 'PC Speaker' level become the master level. How can I do this?
Also, I noticed some occasional pops and clicks during audio playback; any ideas?
The second issue has to do with Macintosh keyboard modifiers and KDE. In my X config I have my keyboard defined as "Macintosh," and I've also instructed KDE to use Macintosh keyboard modifiers. So instead of pressing ctrl + c to copy, I can use the more familiar (to me) cmd + c. However, I use two languages and switch between them with the KDE keyboard switcher; when it changes to another language it overrides my "Macintosh" keyboard setting, and instead forces the keyboard to be a standard 104 key PC. Judging from the keyboard switcher's config file, it uses KDE's keyboard maps, not X's; KDE has no Macintosh keyboard map, but simply relies on its ability to use Macintosh modifiers. Any ideas about this? Must I be stuck with PC modifiers?
The third question is more iMac specific. KDE seems to be putting my Mac's display to sleep, since I can't notice any kind of glow from it even with the lights off. However, it doesn't seem to put the Mac's display into a deep sleep, where all power is cut and it has to warm up again. Is this just typical behavior of the iMac's energy settings? I've only ran OS X on this machine for a few minutes, so never really looked into how it OS X handled power management with it. I've heard once that the CRT iMac displays did not sleep completely, since the heat they generate work as part of the system's cooling convention.
The last issue: I have graphics acceleration working, and I can play back DVDs and some minor GL apps with no dilemma; some more intense GL games seem to lock up X completely though (Tux Racer for example). Why is this happening?
