Hi I've installed Fedora 25 on my Beaglebone Black for the
reasons of
testing packages perhaps doing some quality assurance and helping with
test days. I used the KDE spin and I found that sddm-greeter
constantly consumes high amount of CPU, I can log in and it seem to
kick off KDE and it starts akonadi for a new user. I tried to strace
the process and I found that it calls gettimeofday
frequently, which is expected since it displays the time. I don't have
any explanation about why the CPU is so high. I tried to install
systemtap but I didn't find kernel-debug-core. Is there something else
I should do to debug this, is this a bug and should I report this? I
don't want to waste people's time with a bug that might not be valid
which is why I'm trying to investigate this as much as possible.
I know the beaglebone black doesn't have the greatest resources
available one CPU (1 GHZ) and 512MB RAM and on an sdcard (couldn't
find how to move it to the NAND).
It's because the display on the BBone isn't accelerated using the GPU
and as KDE is all 3D it has to use the CPU for all the rendering. The
beagle bone is not a good device for graphical userspace.
The BeagleBone has an onobard eMMC (like a soldered mSD card) not NAND
storage. Once you've booted off the mSD card you can using the same
process for writing out an image to the eMMC as you did for writing
the SD card.
Ah thank you Peter I didn't think about KDE trying to display OpenGL I will
consider another device for this, and perhaps us the BeagleBone for
narrowing down the problem or something similar. Thank you for time!
