Hi, I tried following lines in weston.ini (Also made sure weston actually loaded it.)
[output] name=LCD mode=240x320 transform=90 I'm not sure what the name should be. Display is connected to parallel port (lcdif1, not LVDS). How can I check what name I should use? As I'm no Wayland/Weston expert I want to use backend/renderer that works. Currently the backend(I think) is FBDev since I'm using linux-fscl-imx - kernel. I think NXP officially doesn't support other atm. I'm not sure about renderer what I'm even using atm. I guess with this DRM/etnaviv I might be able to get Weston 2.0 work as it fixes one annoying bug. I can't do that with the official NXP FBdev driver. -Teemu -----Original Message----- From: Pekka Paalanen [mailto:ppaala...@gmail.com] Sent: 22. kesäkuuta 2017 10:45 To: Jomon John; Keskinarkaus, Teemu Cc: wayland-devel@lists.freedesktop.org Subject: Re: Display rotation in Wayland/weston in imx6sx On Thu, 22 Jun 2017 06:50:11 +0000 Jomon John <jomon.j...@tataelxsi.co.in> wrote: > Teemu, > > >>> There is rotate config(transform) option in Weston, but it did > >>> nothing when tested.

Hi, how exactly did you try that? I think it should work, but if you e.g. used a wrong output name in weston.ini, it will get ignored. Do mention which backend and renderer you want to use. > >> > >>Transform will work, i tried the same on i.mx6 (with DRM backend) > >>and it was working, but you will need mainline kernel.

Kernel support is only necessary if one wants to hit the composite-bypass path if clients are not already rotating as well. I would expect it to work for all of fbdev/pixman, DRM/pixman and DRM/GL. > > At least quick glance to linux-fsl-imx - kernel menuconfig did show > > DRM enabled, but that's pretty much it.

I've asked around recently about that myself, and it seems that while Weston itself will be hardware accelerated ok, the support for Wayland clients is not complete yet. Clients will run, but even with the latest Mesa release, you will probably have tiling mismatch issues which cause the window to appear garbled. I hear the work to fix that is going on right now (support for pixel format modifiers).
