Monitor often fails to wake from monitor sleep.

From: dorayme on 27 May 2010 21:43 Tiger, G4 QS Powermac. Two screens, single desktop. *Never* for computer to sleep but 20 mins set for display sleep in Energy saver panel. Screensaver set to come on after 6 mins. A Dell and a 24" LG (W2452). Both the Dell and the LG run at their native resolutions. The Dell is always quick to wake on mouse movement or keyboard press, the LG always slower but too often failing altogether to wake from monitor sleep and I have to switch the power on and off to it to trigger it back on via the mains at the wall, (the power on the monitor frame is unresponsive in this situation). Any similar experience and ideas on how to fix? -- dorayme

There are times when the computer goes to sleep and only turns off one of the 2 monitors. First one stays lighted up. When I mouse mouse, it goes dark, and then both turn back on. This is on a Macpro with DVI connected NEC monitors.

Yes! - I've now sent my 28" ViewSonic to the factory with a near similar problem, while my other ViewSonic reacts like a dream. The techbuy said that it probably is the PSU in the monitor or the electronically handling that fails, so it might be something similar on your machine. But before deciding anyting... Which graphics card are you using - the std. GForce 2MX/32mb or the larger 4MX/64mb? - Radeon 9000Pro/32mb / 9000Pro/64mb? - 2x DVI connection or DVI+VGA? - and which one is connected then to the VGA (if VGA is used)? - OR - worst case - are you using a Radeon 9200 PCI card for the one monitor? I presume that you are aware of the 'deep sleep' problem on the G4s..., but if you have an extra PCI graphics card, I'll guarantee you that this is the problem.

I rather suspect the energy saving software built into the LG. Not keen to suffer the inconvenience of doing without it to return it on guarantee but I can return it when it is convenient in a couple of years maybe... I have the mains power to it handy on the desk, that kicks it into action. > > But before deciding anyting... Which graphics card are you using... ATI Radeon 9800 Pro: Chipset Model: ATY,R350 Type: Display Bus: AGP Slot: SLOT-1 VRAM (Total): 128 MB Vendor: ATI (0x1002) Device ID: 0x4e48 Revision ID: 0x0000 ROM Revision: 113-A07525-130 Displays: W2452: Resolution: 1920 x 1200 @ 60 Hz Depth: 32-bit Color Core Image: Supported Main Display: Yes Mirror: Off Online: Yes Quartz Extreme: Supported DELL SP1908FP: Resolution: 1280 x 1024 @ 60 Hz Depth: 32-bit Color Core Image: Supported Mirror: Off Online: Yes Quartz Extreme: Supported I have another card in there not being used at all ATI VGA: Chipset Model: ATY,RV100 Type: Display Bus: PCI Slot: SLOT-3 VRAM (Total): 64 MB Vendor: ATI (0x1002) Device ID: 0x5159 Revision ID: 0x0000 ROM Revision: 113-85501-208 Displays: Display: Status: No display connected Display: Status: No display connected but I used to use it and I think I had the same problem with the LG. I might try to confirm this by switching the LG to it. It is a card I also used to have in my 7300 and 7600 to run a LCD screens on 9.2. I think my QS 2002 came with the GForce 4MX/64mb, (its in a box somewhere) and I ran it for years and years but it won't do the res on the LG so i bought the Radeon 9800 Pro and have been happy with it. I have the feeling that this problem of not waking from screen sleep is getting more regular. It does not always happen and I am experimenting on where to leave the mouse cursor, the Dell or the LG and other things to see if it affects it. I should yank the unused display card out and see if this helps. Doubt it! > - the > std.

It is the reason I never put the QS to sleep ever (apart from turning it off now and then). I understand that my USB 2 PCI Belkin card (good quality though it be) might be responsible. Did you know, Erik, that there is a PhD course in the vagaries of sleep on G4 Powermacs? You graduate as a Dr of MacSleep. > but if you have an extra PCI graphics card, I'll guarantee you that this > is the problem. > What is the problem exactly? > Cheers, Erik Richard -- dorayme
