I see, so this seems to be related to the dual-head setup.
YaST currently does not allow to change the screen resolution nor to configure
the
dual-head directly. The installation system already includes the "xrandr"
command
line tool, but that is difficult to use, that's not an option for newbies.
But we could use an existing GUI tool for that, I found out that we have
"lxrandr"
tool in the distribution. It allows switching the screen resolution in a user
friendly way. For resizing the YaST window we can use the "wmctrl" tool, see
item 6)
below.
To include the tools in the installer and test them manually follow these steps:
1) Boot the Leap 15.0 installation with this extra boot option
(internet access is required):
info=https://paste.opensuse.org/view/raw/67301180
This paste includes a list of packages added to the installation system.
Instead
of this "info" option you could write all that "dud" options, but that would
be
annoying. This is a shortcut.
2) Confirm downloading not signed packages (linuxrc cannot verify the
checksums, but
this is safe as the packages are downloaded from download.o.o using the
secure
HTTPS protocol).
3) When YaST displays the first dialog (language and license) press the
Ctrl+Alt+Shift+X key combination to open an xterm window.
4) Start "lxrandr" from the terminal.
5) Now you should be able to set the screen resolutions and configure the
monitors.
I have tested it in a VirtualBox VM where it is difficult (not possible) to
simulate a real dual-head setup. But I was able to change the screen
resolution.
According to this [1] screenshot it should be also possible to enable screen
mirroring or to switch between the laptop built-in LCD and the external
monitor.
6) However, after decreasing the resolution the YaST window became cut-off. I
guess
after increasing the resolution there will be black borders. And because
YaST is
running in full-screen mode you cannot resize it using mouse.
But you can do it manually, from the xterm run:
wmctrl -r YaST2 -e 0,0,0,<width>,<height>
Replace <width> and <height> with the real screen resolution selected in
the lxrandr tool.
Please test it, if that works for you we could possibly include the tools
directly in
the installer and add a new button like "Screen Configuration" into the very
first
dialog to start the "lxrandr" tool. And possibly we could run the "wmctrl"
command
automatically after "lxrandr" is closed.
