Adding the line to .bashrc make it more permanent, but one may soon notice that kde do not ack the new pixel number and that plasmoid, for example, can’t go in the black part.
So, what I need is
first make it permanent.
This will need one of several solutions: add it to a start script, or better add it to /etc/X11/xorg.conf.d files. But does this xorg version understand “option scale-from…”, I couldn’t test it yet, but google say no. The option should be some sort of --transform option, but I couldn’t yet find which gives the same result as scale-from
then make it active before kde start or make kde understand it
may be there is a kde option that makes the two things on one go?
If you want xrandr to work globally, in Plasma as well as other sessions, you can put it in a script in /etc/X11/xinit/xinitrc.d/. I would attach my screenshot showing proof and details, but I can’t find a way here that doesn’t demand being shown via a web URL, so if jdd wants to see he can ask me to email it, or someone can explain how attaching is done here.
That won’t work, since there is no X server running when it’s executed, and even if there was it would need to be run from within the X-session as the session owner or the DISPLAY environment variable needs to be set.
both do what you want for me with Radeon HD5450 in Plasma on TW when placed in /etc/X11/xinit/xinitrc.d/setup, I have to think either your problem has to do with Intel and/or Optimus drivers that works with other drivers, or something was broken in Leap’s Plasma and/or Xorg that is fixed in TW. Have you tried the modesetting Xorg driver build into the server at all?
What’s contrary to what? It’s just as you describe in OP except I use 1680x1050 as lower resolution smaller screen, and 1920x1080 or 1920x1200 as higher resolution to squeeze into the smaller 1680x1050 screen space.
sorry, I was answering to the post of deano_ferrari that showed how to use kde scale system, but do not scale under 1.
The present situation is the following:
I have a mostly working display if I run the xrandr command from the command line (in fact I just click on a script) after complete login Simply a large part of the screen is black. and not kde capable
the same script in .bashrc do not do the panning
what I set in etc/X11/xorg.conf.d (I tried Option panning and Virtual) do not seems to be used, but If I make a typo this prevent X start, so the file is used somewhat.
placing the command in /etc/X11/xinit/xinitrc.d/setup do not work better
The first line create the new hd resolution, better not call it 1920x1080, not to collide with natural names.
The second give it to VIRTUAL1, and magically eDP1 and VIRTUAL1 are connected, eDP1 top left, keep it there. Kde desktop is created from this.
Then scale the screen and all the virtual screen is visible at once
let only speak kde of this startup and voilà.
Of course, full hd on 15"6 screen gives small fonts, but you can use a bit less scaling if you want.
