StealthMode Posted March 15, 2008 Share Posted March 15, 2008 Usually when there is a lot of harddrive thrashing my mouse movement gets glitchy as heck and jumpy. ie. when Transmission is checking a file or Aperture is loading my photo library, stuff like that. I am using Zephs 10.5.2 v1 install and the new speedstep 9.2.0 kernel.

knyte2 Posted March 17, 2008 Share Posted March 17, 2008 I've noticed the same thing when I have my wireless MX Revolution mouse hooked up, not so much with a corded mouse.

hackeron Posted April 14, 2008 Share Posted April 14, 2008 Any solution for this? -- It seems to have gotten really bad after a bios upgrade on an Asus P5K SE -- I will downgrade the bios as a temporary solution but would be nice to find out what is causing this.

Hmm, the weirdest thing - I plugged my monitor into the next DVI output on my 8800GTS and that particular problem went away but now the Shades app doesn't work (http://www.charcoaldesign.co.uk/shades) - when I change the brightness slider, nothing happens Link to comment https://www.insanelymac.com/forum/topic/93767-system-becomes-bogged-down-stutters-jerky-mouse-movement/#findComment-708346 Share on other sites More sharing options...
Software Updater Posted April 14, 2008 Share Posted April 14, 2008 Well it makes sense, loading an iPhoto library takes some serious system resources. It happens on normal macs. Also wireless mice will be blotchy because it is sending the signal across the air waves and there are many things that can cause interference. Read the FCC 155 rule, it says this device may not cause interference and must accept any interference even if it causes unwanted behavior.

Errrr, I'm talking about when the Mac is 100% idle and moving the mouse is sluggish and everything is almost unresponsive, you can't even watch a video without it being choppy -- now you turn off your PC, move your DVI cable from one port on your GPU to another, boot up and it's flawless and very smooth, no mouse jerkiness when loaded a large iphoto album. I'd be happy with this arrangement of moving the DVI to the next port, but if I turn off my screen and turn it back on, I see a blue screen, then I see my desktop flash for a second, then I see a blue screen again and it just stays there -- I have to move my DVI cable to the previous port to see the desktop again at which point I get the extremely sluggish mouse and choppy video playback again.

hackeron Posted April 14, 2008 Share Posted April 14, 2008 Downgraded my Asus P5K SE bios from 1006 to 0901 and the problem is gone.

Only one of your video inputs can be hw accelerated. You need to edit your nvcap settings.

Voyn1x Posted April 17, 2008 Share Posted April 17, 2008 Sounds like it could be the AMD Dual Core bug. See the mammoth thread on it here: http://forum.infinitemac.com/comments.php?...page=13#Item_18 Try adding IDLEHALT=0 to your com.apple.Boot.plist. It solved the issues i was having with my 4200+ X2 Link to comment https://www.insanelymac.com/forum/topic/93767-system-becomes-bogged-down-stutters-jerky-mouse-movement/#findComment-712450 Share on other sites More sharing options...

insomnimac Posted April 17, 2008 Share Posted April 17, 2008 EFI fixes jerky mouse? - I thought EFI was just to fix boot problems? EFI doesn't fix boot problems, on intel macvhines it lets you use the vanilla kernel and lets you install "most" updates. It can also improve hard disk performance in Leo and overall system stability. On my amd machine I get the weird mouse movement when my machine has been on for about 12 hours and I return to it after work, I have to do a restart. Still don't know what the solution is though but EFI has fixed it on a few pcs.
