Weston log from running on a uaccess permissions fb device, and to a different
tty and back
Hi.
I have configured my framebuffer devices with udev to have uaccess, similar to
how it sets up /dev/dri/card* devices
I added this line to my udev config:
SUBSYSTEM=="graphics", KERNEL=="fb*", TAG+="uaccess"
I am able to start Weston sessions fine on this configuration.
but when I switch to a different tty, and then switch back, it seems the
permissions to /dev/fb0 are lost and Weston dies.
I am using Ubuntu, which means, I am using the limited logind. And I am calling
my user sessions from weston-launch.
If I'm really careful, I can switch tty without crashing with
'loginctl activate', but once I switch TTYs, All instances of weston lose
permission to /dev/fb0 once I switch to them, even if the next way is with
loginctl activate.
It seems to work with /dev/dri/card* and /dev/input/event*, so it should work
with /dev/fb* I would assume?
I have a log of a Weston crash attached.
