freak Posted March 16, 2020 Share 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 Share 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 Link to comment Share on other sites More sharing options...
JimMacbeth Posted March 23, 2020 Share 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. Link to comment Share on other sites More sharing options...

CluelessLee Posted March 23, 2020 Share 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 Link to comment Share on other sites More sharing options...
CluelessLee Posted March 23, 2020 Share 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 Link to comment Share on other sites More sharing options...
Igor Posted March 23, 2020 Share 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 ... Link to comment Share on other sites More sharing options...
