Display Resolutions/Freq., MDD, R9000, Leopard
I have an MDD hooked up to an older IBM (T85A) LCD and I can't get it to display in anything other than 1152 X 870 @ 75Hz. The display supports up to 1280 X 1024, and on the exact same machine, when I boot the Tiger volume, 1280 X 1024 works fine. But in Leopard, every resolution except 1152 X 870 causes the monitor to fail to synch. The basic resolutions, 640 X 480, 800 X 600, 1152 X 870 and 1280 X 1024 are available for selection. Also a few other 1152 X ? resolutions. The frequencies other than 75 Hz are grayed out. I tried it on a different display and I get the same results, so I'm pretty sure it's not a display failure. Plus there's the part where it works fine in Tiger. Even 640 X 480 and 800 X 600 fail to work (no sync) under Leopard. The video card is a stock ATI Radeon 9000. The display is connected via VGA through a DVI to VGA adapter. I tried downloading the ATI 4.5.7 drivers and installed them, but, while I can see that it added some components, it does not seem to have affected the issue. I'm pretty sure it used to work, before I had a hard drive failure (the Tiger drive, not the Leopard drive) and started the reinstallation process. Somewhere along the way I replaced the PRAM battery and zapped PRAM and I think that's when the display choices stopped working. According to the documentation, the display supports these modes: VGA: 640x350 70Hz 640x480 60, 66 (MAC), 72, 75Hz 720x400 70Hz SVGA: 800x600 56, 60, 72, 75Hz 832x624 75Hz (Apple) XGA: 1024x768 60, 70, 75 (MAC), 75Hz 1152x870 75Hz (Apple) SXGA: 1280x1024 60, 72 (HP), 75, 76Hz (Sun) So, when I choose 640 X 480 @ 75 Hz in Leopard, it ought to sync, but it doesn't. Yet it works in Tiger. It's like nothing but the default resolution in Leopard is actually working properly. Any ideas?

July 2012 From:t...@prismnet.com t...@prismnet.com To: G-Group g3-5-list@googlegroups.com I have an MDD hooked up to an older IBM (T85A) LCD and I can't get it to display in anything other than 1152 X 870 @ 75Hz. The display supports up to 1280 X 1024, and on the exact same machine, when I boot the Tiger volume, 1280 X 1024 works fine. But in Leopard, every resolution except 1152 X 870 causes the monitor to fail to synch. Try booting in safe mode. http://support.apple.com/kb/HT1455 1. Be sure your Mac is shut down. 2. Press the power button. 3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone. 4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear). The video card is a stock ATI Radeon 9000. The display is connected via VGA through a DVI to VGA adapter. Don’t know… normally Leopard handles displays much better than Tiger and previous Mac OS X versions did. How I understand it, Leopard interprets the EDID information from the display and sets the modes accordingly. http://en.wikipedia.org/wiki/EDID I tried downloading the ATI 4.5.7 drivers and installed them, but, while I can see that it added some components, it does not seem to have affected the issue. The ATI Radeon 9000 graphics card works out-of-the-box with all Mac OS X version from 10.2 onward (on PowerPC, not on Intel). I'm pretty sure it used to work, before I had a hard drive failure (the Tiger drive, not the Leopard drive) and started the reinstallation process. Somewhere along the way I replaced the PRAM battery and zapped PRAM and I think that's when the display choices stopped working. The last graphics mode is stored in PRAM and reused, even if you enter Open Firmware (by holding Opt+Alt+O+F). This can sometimes be kind of annoying, because scrolling in unaccellerated graphics mode (like in Open Firmware) is getting slower with higher resolutions/color depths. According to the documentation, the display supports these modes: VGA: 640x350 70Hz 640x480 60, 66 (MAC), 72, 75Hz 720x400 70Hz SVGA: 800x600 56, 60, 72, 75Hz 832x624 75Hz (Apple) XGA: 1024x768 60, 70, 75 (MAC), 75Hz 1152x870 75Hz (Apple) SXGA: 1280x1024 60, 72 (HP), 75, 76Hz (Sun) Any ideas? You may try adding this line to kernel boot args: Graphics Mode=1280x1024x32@60 1st Method: com.apple.Boot.plist Do this from you woring Tiger installation: 1. Boot into Tiger 2. Start Terminal.app 3. Type: sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist (or, if you’re more confortable with Textedit:) sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /Library/Preferences/SystemConfiguration/com.apple.Boot.plist Add/Change the following key: keyGraphics Mode/key string1280x1024x32@60/string 4. Save, and reboot. 2nd Method: Firmware Do this from you woring Tiger installation: 1. Boot into Tiger 2. Start Terminal.app 3. Type: sudo nvram boot-args=\Graphics Mode\=\1280x1024x32@60\ (you can copypaste this line in terminal if you want: Cmd+C, Cmd+V) 4. Reboot… This is easily reversible: In 3., type sudo nvram boot-args= Alternatively you can reset everything by holding Cmd+Opt+P+R when you hear the chime, until you hear it again (to be safe, until you hear it three times in total), then release the keys (and hold the Opt key after the third chime if you want to select the OS you want to boot into).

Re: Quad G5 power consumption
see http://support.apple.com/kb/TA24037 165W idle, 550W max, so probably 400W-450W or so. 2400W can be a problem, a normal single 15A outlet won't handle it. And 2.4KWH cost me nearly 40cents and hour. That's $10/day. A lot of money to tinker around.

If this adapter uses a cable to adapt a standard DB9 to the Mac DB8 then you can likely use it with OS X. You'd need to determine the chipset used in the adapter and then find an OS X extension for it. You can probably plug the adapter into the USB and look in System Profiler to see about the chipset. It may be a Prolific Logic PL-2303 which has OS X drivers. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: Quad G5 power consumption
see http://support.apple.com/kb/TA24037 165W idle, 550W max, so probably 400W-450W or so. As a real world figure: my quad G5 routinely runs at near full tilt when building TenFourFox. At Highest Performance, 2 7200rpm SATA drives, 7800GT video card and two USB-FW expansion cards, it pulls around 300-400W. Lightly loaded, as I type this message in Reduced, the power supply meter says it is drawing 230W.

Besides, from my own UPS panel and dual 2 gHz G5, each will use a little over 220 watts at idle. You can also save 50-60 Watts just by using the base line video card over, say, a Radeon 9800. By the way, the CPUs (as you probably know) use different amounts of power, if you were willing to use Bresinks' Hardware Monitor and change cpus around, you could save 20-50 Watts by using only the less leaky CPUs.
