update-alternatives --install /usr/bin/x-www-browser x-www-browser /usr/bin/dwb 100
Add dwb to x-www-browser list and set it's priority to 100
Slim notes to keep in mind
This file determines the default display manager
Would be for gdm3
Sets slim as the default display manager
qingy - is another choice
Contain the settings for gdm3
This line will instructs whether gdm3 should
respect the default, if set to false, it
can run at same time as another.
i3 as default window manager with slim
sudo update-alternatives --install /usr/bin/x-window-manager x-window-manager /usr/bin/i3 200
Set i3 to have a higher priority than it did before.
Slim is reading gnome-session as the default, when
logging in. I want it to be i3.
Even if this file has i3 as the first option under
sessions. Slim still defaulting to gnome.
Now create or edit and add:
Slim's default is now i3!
The culprit seems to be this file:
# If there is still nothing to use for a startup program, try the system
# default session manager, window manager, and terminal emulator.
if [ -z "$STARTUP" ]; then
if [ -x /usr/bin/x-session-manager ]; then
elif [ -x /usr/bin/x-window-manager ]; then
elif [ -x /usr/bin/x-terminal-emulator ]; then
So two other options may be to try to set:
As i3. I don't know what will happpen.
Or to change these lines, so that it reads
Of course if you ever stop using i3 these will
need to be changed back, especially if change to
Not sure which of the three is best, but right
now I'm using .xsession = exec i3
Ok I removed .xsession and swapped the if statements
around and it still works.
ps -aux | wc -l
Shows 130 process running this way.
back to the original way and putting
ps -aux | wc -l
So take you pick. The .xsession way seems to be
the easier one to alter if future changes occur.
Might even be able to use it to jump to bspwm
and not have to change all the other debian
config crap. Not gonna try setting i3 to
x-session-manager, already have to fixes.
I do have i3 first in:
If that makes a difference.
And I was rebooting for these to take effect.
Not sure if there is a way to reload on the fly.
