Hello,
I edited /var/lib/dietpi/dietpi-autostart/custom.sh file by adding line below:
xinit ‘/usr/bin/surf’ -F ‘https://google.com’
Legend:
Page is opening in browser but only on the 1/4 of the screen (I have FullHD monitor).
Any idea what should I change to make it working on all screen area and is it possible to rotate the screen? I must do kiosk with simple, static webpage.
Best Regards
Hi,
Is there a reason why you did not use Chromium? Its offered by DietPi and easy to run in Kiosk mode.
I have BANANA PI BPI-M1 SINOVOIP with A20 ARM Dual-Core (1GHz).
When I run chromium, it takes about ~12% of CPU Time and ~12% of RAM. The same page opened in surf takes only 1,3% of CPU and 5,8% of RAM.
That is why I try to use surf. It is much smaller, but with my SBC and webpage which I want to display, it is very good.
BTW. Chromium also did not open on full screen. Its open webpage in little wider window, but it is still about 1/4 of screen.
basically if you like to use chromium, you would need to activate chromium resolution settings in dietpi.txt
# Chromium
SOFTWARE_CHROMIUM_RES_X=1920
SOFTWARE_CHROMIUM_RES_Y=1080
SOFTWARE_CHROMIUM_AUTOSTART_URL=https://dietpi.com
I think I’ll use chromium. I don’t have enough knowlege to switch it to surf browser.
But maybe you’ll know if DietPi can rotate screen 90* clockwise?
yup, you can rotate your screen
there you can rotate
I searched in dietpi-config and can’t find it. But after your post I checked once again and indeed don’t have it.
In Display Options i have:
1: Display Resolution,
2: GPU/RAM Memory Split,
3: LCD Panel addon: [none],
16: Display Brightness,
17: X.Org DPI: [96]
14: Led Control
There is not option nr 4. Maybe it’s because my board?
yep indeed this is depending on your board. but I found this one one the web
https://bananapi.gitbooks.io/bpi-m3/content/en/howtorotatedisplayscreen.html
this might be the file to adjust for the xserver
/etc/X11/xorg.conf.d/99-dietpi-dpms_off.conf
Probably you can create an additional file to add the command to rotate
/etc/X11/xorg.conf.d/01-rotate-screen.conf
Unfortunately I’m not able to test as I didn’t have such a board.
EDIT:
Ok. I found that xrandr can generate scripts to rotate screen. I copied command from that script to custom.sh file.
Now file looks like below, but xinit start and display console… xrandr and browser don’t run. What should I do to make commands to run one after the other?
xinit
xrandr --output HDMI-1 --primary --mode 1920x1080 --pos 0x0 --rotate left
‘/usr/bin/surf’ -F '> http://dietpi.com> ’
I put below lines:
Section “Device”
Identifier “Raspberry Pi FBDEV”
Driver “fbturbo”
Option “fbdev” “/dev/fb0”
Option “SwapbuffersWait” “true”
Option “rotate” “cw”
EndSection
into file /etc/X11/xorg.conf.d/99-dietpi-dpms_off.conf and tried with new file named /etc/X11/xorg.conf.d/01-rotate-screen.conf. Unfortunatelly without success.
Maybe logs tell you something?

Rotate screen must be possible because when LXDE is launched I can rotate screen with xrandr. Just don’t know how to do it without LXDE.
how does it behave if you execute xrandr once chromium was started? so open a SSH session after browser start and do:
DISPLAY=:0 xrandr --output HDMI-1 --rotate left
I do not run xrandr when chromium was started. I move back and change autostart option to 16:LightDM login mask.
Then I play around with xrandr and generate script with command which I want to run from custom.sh file.
try to run chromium on autostart. once started, open a SSH session and execute the following
DISPLAY=:0 xrandr --output HDMI-1 --rotate left
Hello,
Thank you for your sugesstion.
Your command rotates screen, but … it looks like in the below picture.
I tried many different combinations, but I don’t know how to strech the picture to the monitors resolutions…
which browser you are using now?
This is chromium. When screen is not rotated, everything is ok - it covers all screen area. But when I rotate it to left it looks like in the picture.
Maybe changing resolution from 1920x1080 to 1080x1920 could help? But when I tried to run xrandr with -mode 1080x1920 I got error that there is no such mode.
Did you already try to switch the dietpi.txt Chromium resolution settings?
SOFTWARE_CHROMIUM_RES_X=1080
SOFTWARE_CHROMIUM_RES_Y=1920
Yes, I set it up, and before rotating it looks ok (look at screenshot below).
But when I rotate screen it looks like it rotates without changing resolution from 1920x1080 to 1080x1920 (I think…)
Helped changing resolution for chromium in dietpi.txt from
Chromium
SOFTWARE_CHROMIUM_RES_X=> 1920
SOFTWARE_CHROMIUM_RES_Y=> 1080
SOFTWARE_CHROMIUM_AUTOSTART_URL=> https://dietpi.com
to
Chromium
SOFTWARE_CHROMIUM_RES_X=> 1080
SOFTWARE_CHROMIUM_RES_Y=> 1920
SOFTWARE_CHROMIUM_AUTOSTART_URL=> https://dietpi.com
Now it looks like I wanted 
But after restart, screen rotate backs to its previous setting. What should I do to make it permanent?

You used DISPLAY=:0 xrandr --output HDMI-1 --rotate left besides the resolution switch, right?
echo -e '#!/bin/dash\nDISPLAY=:0 xrandr --output HDMI-1 --rotate left' > /var/lib/dietpi/postboot.d/rotate_screen.sh
This does the rotation at the end of boot, right before login/Chromium autostart. Should be what you need, but if it should be done on earlier boot stage, a dedicated systemd unit would be required.
yep xrandr is going to rotate screen juts for current session. It’s not a permanent rotation. So would need to be done right after boot as indicated by MichaIng
