required udev rule
Hello!
I'm using framebuffer-based applications like fbida or mplayer on the
virtual-terminal. This requires my user to be in the "video", or in a more
Systemd fashioned-way, apply a UDEV-Rule with the TAG "uaccess" to the specific
framebuffer-device (in most cases "/dev/fb*").
Switching between the virtual-terminals works fine. Switching from X11 to a
virtual-terminal, which currently uses a framebuffer-device, freezes the
display with last output from X11. The programmatical switch to the
virtual-terminal itself works, i.e. the application running their will accept
keyboard instructions.
Step to reproduces:
1. Login to a random virtual-terminal, view a image with fbida or a movie with
mplayer
$ fbi random.png
$ mplayer -vo fbdev funny.ogg
$ mplayer -vo fbdev2 more_fun.mpeg # if previous doesn't work
2. Login to X11
3. Switch with Ctrl+Alt+F-Key to the virtual-terminal used before
4. Display output freezes
Workaround:
Switch to another virtual-terminal which currently doesn't use a
framebuffer-device. From their, a user can switch to any other
virtual-terminal.
Thank you for your work</pre>
