Open Power Statistics and click Processor.

This issue was not caused by #303. I tested 1.22 and git master with and without that patch applied.

flexiondotorg commented 4 years ago

I have just tested Ubuntu MATE 19.04 with mate-power-manager 1.20.3-2 and upower 0.99.10-1 and the same issue is present.

I can confirm the issue with released 1.22.2/1/0 and upower-0.99.10/9.

CONFIG_TIMER_STATS was removed from Kernel https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.19-rc6&id=20dcfe1b7df4072a3c13bdb7506f7138125d0099

/proc/timer_stats (from Linux 2.6.21 until Linux 4.10) http://man7.org/linux/man-pages/man5/proc.5.html

Now i know why gnome-power-statistic doesn't display it any more, only my mouse device. Bildschirmfoto zu 2019-09-26 15-28-48

So we need that? https://gitlab.gnome.org/GNOME/gnome-power-manager/commit/8621440250db093f7ec614193126ada1f2eedd9e With a check for kernel-version?

flexiondotorg commented 4 years ago

Probably just drop it. Eventually there will be no kernels that support the feature.

Question is, what UI changes are required? On my desktop and VMs the only thing I see in Power Statistics is the broken time stats.

lukefromdc commented 4 years ago

This is confirmed here too, on kernel 5.3.0 and I concur that if it depends on a no longer avaliable kernel feature we should drop it.

GNOME did manage to find another way of doing this (at least with 2018 kernels) in their gnome-usage application if anyone wants to find a way to bring it back-or fork that whole application and port it to the MATE user interface for that matter.

Yes, broken in latest linux mint. :(
