xrandr problem in display rotation

[marco_padovani]

Hi, 

i have a problem with HDMI display rotation on iMX6. I'm using a Congatec Module that mount a iMX6 Solo.

I have a TFT Monitor 7' with resolution 800x480.

With a init script i define the resolution at startup:

xrandr --newmode "800x480_60.00" 60 800 824 896 992 486 483 493 500

xrandr --addmode DISP3\ BG\ -\ DI1 800x480_60.00

xrandr --output DISP3\ BG\ -\ DI1 --mode 800x480_60.00

and the display view and resolution is ok:

but when i send command "xrandr -o left" the display rotated with error, because the top bar goes in the bottom and crop the screen:

There are similar problem when the rotation is "right" but display shifted down.

Anyone have an advice to fix the problem?

Thanks,

Marco

Hello Marco,

Current xrand is supported however there are some features that are not working well, as example this and the acceleration by GPU, this is marked as a bug.

Hi  Bio_TICFSL, 

thanks for your support. 

Do you known if there are workaround to rotate the display correctly? Or an xrandr version upgrade is required?

I try to set resolution to 640x480 and the screen is used in a reduced way, but when i rotated the display the rotation is good (always in a reduced way but is correctly).

Thanks, 

Marco
