It takes a long time to appear and disappear. Has this changed since 13.1 (or some other release?). Battery life on XO-4 C2 seems significantly improved over previous builds. We would be interested in a confirmation or otherwise of this in the power log analysis. I guess you are comparing to 13.1.0 build 36? The big difference here is that 13.1.0 build 36 has automatic power management disabled, it is now enabled in 13.2.0 (not 100% stable just yet, but we continue to shake out the bugs).

We turned off unused cores and in q7b23 and that made almost 800mW worth of difference across the board in operational power draw. I'll do a plot of your power logs though and confirm. -- Richard A.

Karearea was the laptop with the problems in addition to the sound. There is at least one logfile from a boot on the old firmware with working sound so don't be confused by that.

We didn't notice any problems with suspend-resume. I remember thinking that the wifi took a long time to come back but I didn't investigate this. 1320-crash.txt.tar.bz2 Description: application/bzip ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

It's quite annoying if you happen to build something in physics that extends to the top of the screen and certainly doesn't look good when you show people the laptop. I have a patch from John that fixes this, it's related to hardware driver frame buffer support issues, but at the cost of some memory performance cycles. Basically it removes pygame default screen buffering feature and does the buffering manually – no more white flicker at the top of the XO-1.75 redraw cycle, but not for free. Is this as a workaround for a bug in pygame and/or the graphics drivers? Can you isolate the change to XO-1.75 only? The other hardware seems to work fine and doesn't need a performance hit. Are you able to synchronize with the vertical blanking interrupt? I once wrote a hack for an Amiga with an add-on graphics card that didn't drive the vertical blank interrupt to busy wait until the vertical blank started. It had a timer and kept the busy wait period small but not so small that it would miss the start of the vblank.. This stopped icons flickering when you dragged them. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
