![]() I also used the code from Arch wiki to turn off the dGPU and blacklisted nouveau. My display brishness is at the lowest state, I use the ethernet adaptor instead of wifi and have nothing else connected. Running for 480 seconds (48 samples at 10 second intervals).ĪCPI battery power measurements will start in 0 seconds time I keep earing this laptop should be arround 12 in Intel GPU, but I have twice that This has the downside that it increases the Mac's power usage, and therefore decreases battery life.Can someone here share his/her actual power usage? I just installed Linux again on the Mac (debian, this time, I had Gentoo and Arch before, but I use this laptop for work and sometime, it just has to work). Normally the GPU in use is opaque to the user, so using an app such as gfxCardStatus is helpful to see what is happening.Īs a workaround, use the gfxCardStatus app to force the Mac to use the discrete GPU while working in Eclipse. You can force the Mac's graphics to switch between integrated GPU and discrete GPU using the free gfxCardStatus app ( ), or let OS X decide naturally depending on what apps are running. The MacBook I am using is mid-2012 Retina MacBook Pro - the integrated GPU is an Intel HD Graphics 4000 1024 MB. It also appears that the problem only occurs when the MacBook is using its integrated GPU, and it does not occur when using its discrete GPU. This problem did not exist in Eclipse Luna (4.4.2) it appeared in Eclipse Mars (4.5.0). Anything that causes a repaint of the editor, such as a change of window focus, will fix the problem. However the problem is frequent enough that it makes working for hours in Eclipse Mars difficult, as there will be frequent corruptions of the editor pane, meaning you can no longer trust what you see in the editor. This problem is intermittent: it might take 30 seconds of scrolling up and down to duplicate, or it might happen immediately. Scroll up or down quickly in a reasonably large file (say 400+ lines) then stop the inertial scrolling by tapping and holding on the trackpad. The problem was seen scrolling with the MacBook's built-in trackpad. On Mac OS X, scrolling the Eclipse editor pane sometimes results in a corrupted repaint of the pane (see attached screenshot).
