I have been using KDE5 since the 14.10 dual release, and there are two
bugs that persist that I would like to tackle.
1) Most though not all of the time when I log out/shut down and then log
in again, if I had a konsole open in the old session it will not be there
in the new. I am fairly sure that this is due to a crash in konsole when
it receives the shutdown signal. I believe this because once or twice I
have seen the crash reporter open just before the system turned off.
I've once read a long analysis what goes wrong with konole session management
and session management in general. Worth reading, saves you lots of time I'm
sure but could not find it right now. Good luck with google ;-)
Wow, I figured out how to reproduce the problem, and I think I know why no
one else might have seen this.
To start with, I should note that my machine has an nVidia card (a GEForce
GTX 560M) and I use the nVidia proprietary driver.
I have long noticed that for some reason, Firefox (my preferred browser)
makes the graphics card spin up all the time. The slightest touch on the
scroll bar, for example, sends the GPU clock to the highest rate, which
causes the GPU to run quite hot and the fan to spin up.
To counter this, I add this to the xorg.conf
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222;
PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"
Option "Coolbits" "9"
Option "UseEdidDpi" "FALSE"
Option "DPI" "96 x 96"
EndSection
This pegs the clock speed to its lowest level, which is fine except for
watching videos.
So, when these powermizer settings are in effect WHEN THE MACHINE IS
STARTING UP (!) and there is a full screen firefox open, konsole fails to
reopen - even if the settings were not in effect when the machine was shut
down. It will often, though not always, fail to reopen even if konsole is
the only thing on the desktop.
This is new to kde5 - everything was fine in kde4.
So, my question is: anyone know where should I report this bug? Is it a
konsole problem or a plama problem?
