etherealglimpse Posted January 2, 2011 Share Posted January 2, 2011 I have osx 10.6.5 running with chameleon rc5 acer 23 inch p235h lcd monitor x58a ud3r rev 2.0 FD radeon hd 5770 ati Mouse lags and jumps and skips all the time. I tried the disabler text to disable appleupstreamuser.kext and I put it in E/E and that did not work. I deleted it from S/L/E and that did not work. I have another monitor a small dell 19 inch monitor. When I use that the mouse works fine. I would 1000000x rather use the acer monitor than this one. I've tried going back to chameleon rc4 and it seems to happen with that also. The other time it worked fine was when I used 10.6.3 alone with a bootcd I didn't install chameleon at all yet. I have no idea. This is a recent thing and I can't for the life of me, figure out what I changed. I did a clean install with 10.6.4 and still had issues.

MasterLen Posted January 2, 2011 Share Posted January 2, 2011 This issue has nothing to with your hack. I have the same issue with my ATI 5770! Many real Mac Pro users have this issue... Apple's Driver causes the mouse lag with some Displays....

Argh, so if I change my display it should fix things? Which display might someone recommend in the 23inch range that doesn't give this problem with dual dvi. I would really like to get a display that works. preferebbly less than 300 plz. thanks. Edit: I'm going to try out that sapphire cable for displayport first, but I do welcome any recommendations on monitors that work for sure with a ati 5770 1gb.

Changing your display could fix this issue but I am not sure which display will work and which will not! I am searching for a solution too. This is an "try and error"!

kennysynth Posted May 26, 2013 Share Posted May 26, 2013 I've got the solution by just getting rid of AppleUpstreamUserClient.kext in S/L/E. Hope this work for you.
