[SOLVED] Screen rotated 90° at boot up

Hey,

I've got a widescreen display had to rotate it in order to work on some large excel sheets, so I turned my monitor and used the following command to rotate the screen. Everything went fine, I finished my work and reverted the setup using

xrandr --output DVI-1 --rotate (left | normal)

However, after a reboot my screen is 90° left rotated and I have to toggle the respective command everytime to fix this, which I changed to

xrandr -o (left | normal)

, btw.

No config were changed, no warning/error message popped out - I'm very curious why my screen got stuck at this rotation. My AMD R9-280X uses the open source driver, those are my xorg configs, if relevant:

Which Desktop Environment/Window Manager are you using?

OP updated his post with

EDIT: Sorry, DE is Cinnamon.

What's the output of 'xrandr' before you fix the display and after?

Re: [SOLVED] Screen rotated 90° at boot up

It's the exact same output:

Screen 0: minimum 320 x 200, current 2560 x 1440, maximum 16384 x 16384
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
DVI-1 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm
   2560x1440     59.95 +
   2560x1440_75.00  74.94*

Re: [SOLVED] Screen rotated 90° at boot up

Well,

I first tried to "fix" this by adding the command to my .xinitrc, but it didn't work. So I added a startup entry and my monitor's rotated normal on boot again. Does anyone have a clue what's causing this behaviour? I wouldn't call this workaround a fix...

Post that ~/.xinitrc with the "fix".

Re: [SOLVED] Screen rotated 90° at boot up

Nothing special, just the above mentioned command:

#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)

if [ -d /etc/X11/xinit/xinitrc.d ]; then
        for f in /etc/X11/xinit/xinitrc.d/*; do
                [ -x "$f" ] && . "$f"
        done
        unset f
fi

xrandr --output DVI-1 --rotate normal
xrandr -o normal

/usr/bin/xscreensaver -no-splash &
xbindkeys

exec cinnamon-session

Creating a startup entry in cinnamon worked however..

Re: [SOLVED] Screen rotated 90° at boot up

Out of curiousity, I checked System Settings > Display, rotation was set to normal as supposed to be but I applied the settings without changing anything anyway and now my screen is rotated normally again on boot.

Strange, but now it's solved - my custom start up entry can be deleted.
