the overlay is needed for mir-kiosk to allow it to work at all (unaccelerated though)
to have mir-kiosk fully accelerated one needs to use -kms-v3d instead but this in turn disables all video decoding in the vc4 core. i originally picked -fkms-v3d for the gadget since it is the least evil (makes mir semi-work while still allowing to use omxplayer accelerated (see the omxplayer-pi snap for testing)). long term it would be really cool if the graphics overlay selection could be a bit more dynamic (this is indeed orthogonal to this bug though) without the need to hardcode such stuff on boot or if mir-kiosk could simply work on top of vc4 without need for the overlay (the mir team was looking into that but i do not know the current status). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1837209 Title: Splash screen fails to display on recent pi core18 images Status in Snappy: New Status in linux-raspi2 package in Ubuntu: New Bug description: The current core18 image [1] for the raspberry pi fails to display the "Core" splash screen on boot. This is because psplash fails to open the /dev/fb0 framebuffer device, because it doesn't exist. This appears to be due to a lack of supporting kernel modules in the initrd.img (fb_sys_fops, drm, vc4, etc.) which were formerly present but are missing from the version I'm testing (pi-kernel 4.15.0-1041.44, snap rev 42). Steps to reproduce: * Flash the image to a uSD card and boot the pi with it (preferably with a serial console attached). * Note screen remains black instead of displaying the familiar "Core" text under an Ubuntu logo. * If serial console is attached, note "Error opening /dev/fb0" in the output shortly after u-boot starts the kernel; this is output from psplash failing [1] http://cdimage.ubuntu.com/ubuntu-core/18/current/ubuntu- core-18-armhf+raspi3.img.xz To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1837209/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
