Cant rotate screen

[VietTralala]

Hi, I am trying to programmatically rotate my screen with the command: python gnome-randr.py --output HDMI-1 --rotate left

However I get the following message:

new monitor configuration:
logical monitor 0:
x: 0 y: 0, scale: 1.0, rotation: left, primary: no
associated physical monitors:
    HDMI-1 1920x1080@60,000

Traceback (most recent call last):
  File "/home/viet/Downloads/gnome-randr.py", line 860, in <module>
    dc_iface.ApplyMonitorsConfig(config_info.serial,
  File "/usr/lib/python3.10/site-packages/dbus/proxies.py", line 141, in __call__
    return self._connection.call_blocking(self._named_service,
  File "/usr/lib/python3.10/site-packages/dbus/connection.py", line 652, in call_blocking
    reply_message = self.send_message_with_reply_and_block(
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.InvalidArgs: Config is missing primary logical

Do you know what went wrong?

Hi! It looks like you don't have a primary monitor set. I haven't encountered that before, but am not sure it's a bug -- Gnome is likely treating it as primary since it's the only one, and that may be the correct behavior...

I suspect running python gnome-randr.py --output HDMI-1 --primary --rotate left will work, could you give it a try?

[VietTralala]

Thanks for the quick response! I tried your suggested command and it rotated my HDMI-1 screen. However I actually use my other screen (DP-1) as the primary one in normal orientation and your command deactivated the DP-1 screen. So I thought I specify the second screen as well:

python gnome-randr.py --output DP-1 --rotate normal --primary --output HDMI-1 --rotate left

Since I sometimes want to switch my HDMI-1 from normal orientation to left portrait mode while leaving the DP-1 screen in normal orientation.

However this resulted in:

new monitor configuration:
logical monitor 0:
x: 0 y: 0, scale: 1.0, rotation: left, primary: no
associated physical monitors:
    HDMI-1 1920x1080@60,000

No problem -- and that is odd ... I wonder why DP-1 doesn't show in the associated physical monitors list? I am currently traveling so won't be able to test multiple monitors myself for a bit, but I've used it to rearrange monitors before with --right-of and --left-of, and that looks right.

Do you happen to have "Workspaces on primary display only" set?

[VietTralala]

I am using dynamic workspaces on all displays. Maybe this info helps: Output of python gnome-randr.py --current:

And I also had to slightly change a line 165 in the script to account for floating number with a , instead of . as decimal separator (German language vs English):

 def mode_id_to_vals(mode_id):
     w, h_rate = mode_id.split('x')  
     h, rate = h_rate.split('@')   
     return (int(w), int(h), float(rate.replace(',','.'))) # <--- this was changed

But I don't think this is important here right?

Same issue, I have 2 monitor 'mirrored', I can't keep 1 monitor --rotate normal and the other --rotate inverted, with xrander I could.

python3 gnome-randr.py --output HDMI-1 --rotate normal --primary --output DP-1 --rotate inverted
new monitor configuration:
logical monitor 0:
x: 0 y: 0, scale: 1.0, rotation: inverted, primary: yes
associated physical monitors:
    DP-1 1920x1080@60
    HDMI-1 1920x1080@60

no changes made

Yes, I can rotate monitors, but the command affect only the monitor DP-1 no really matter about HDMI-1, all commands given to HDMI-1 are compleately ignored. It seems that in order to rotate monitors into 'mirror-mode', none of xrandr features can be usable, probably wayland not allow it.
