freak Posted March 16, 2020 Posted March 16, 2020 Using Linux tinkerboard 4.19.69-rockchip #5.95 SMP PREEMPT Mon Sep 2 07:34:36 CEST 2019 armv7l armv7l armv7l GNU/Linux Using glxgears as a test case.. I get 60fps without the screen rotated. If I rotate the screen right or left the frame rate drops to 4fps. That's on a fresh boot with nothing else running. I tested TinkerOS on the same board and it works fine rotated. My Raspberry PI 4 works fine rotated as well. What could be the problem with Armbian?

CluelessLee Posted March 20, 2020 Posted March 20, 2020 Hi first post here. I had been wrestling with TinkerOS but discovered Armbian and so far am super impressed with this one caveat. I too am experiencing the same issue, a web page's performance when running with a normal view is significantly quicker than when its rotated using xrandr I have tried the current buster build and used buster_legacy_4.4.213. Both appear to have the same issue, but I am very open to having got something wrong. The monitor(s) I have tested with all worked with a similar script when using TinkerOS. All help would be gratefully received. My bash script that runs on boot #!/bin/sh export DISPLAY=:0 # Rotate the screen 90 degrees left xrandr --output HDMI-1 --rotate left # Rotate the touchscreen settings by 90 degrees left xinput set-prop 'wch.cn USB2IIC_CTP_CONTROL' 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1 xset -dpms xset s noblank xset s 300 openbox-session & chromium --no-first-run --disable --disable-translate --disable-infobars --disable-suggestions-service --disable-save-password-bubble --start-maximized --kiosk --disable-session-crashed-bubble --incognito https://bbc.co.uk
JimMacbeth Posted March 23, 2020 Posted March 23, 2020 Hi all, How funny this is my first post here and I see it's about exactly the same issue that CluelessLee posted as his first post. I have done more or less exactly what he has done and when rotated it is extremely slow at rendering the screen as opposed to acceptable rendering when un-rotated. Has anyone successfully rotated the screen with good results, if so can you help, otherwise can anyone give me some indication on what I might be able to do before I sadly have to look at a different Tinkerboard OS? Many thanks.
Igor Posted March 23, 2020 Posted March 23, 2020 Try Settings -> Window manager tweaks -> (disable) Enable display compositing
CluelessLee Posted March 23, 2020 Posted March 23, 2020 Hi Igor, Thank you for your response. Apologies for the delay, I had to flash the OS onto my tinkerboard again. I would say it has made a slight improvement but it's still very slow when rotating 90 degrees left. I have tried 2 different monitors. Any other suggestions would be very much appreciated. Thanks Lee
CluelessLee Posted March 23, 2020 Posted March 23, 2020 I would prefer to run this in Buster, as I am trying to make this as lightweight as possible. Is there a similar setting in Buster that I could try with? Thanks Lee
Igor Posted March 23, 2020 Posted March 23, 2020 20 minutes ago, CluelessLee said: similar setting No. Then this probably going deeper which is not so simple and would require few days of R&D. According to our staff and budget, not this year ...
