Since vmlinuz-6.1.0-12-amd64 my dvb-s2 card don't work anymore

[therealcyclist]

Hello,


maybe someone knows more than me.

If i boot the new kernel vmlinuz-6.1.0-12-amd64 my dvb-s2 card is not 
detected.

if i boot vmlinuz-6.1.0-11-amd64 everything works as usual.

Error with vmlinuz-6.1.0-12-amd64:

Sep 11 12:23:44 kernel: dvbdev: DVB: registering new adapter (SMI_DVB)
Sep 11 12:23:44 kernel: failing symbol_get of non-GPLONLY symbol 
m88ds3103_attach.

Sep 11 12:23:44 kernel: DVB: Unable to find symbol m88ds3103_attach()


greetings

I have tested debian 12 not 11.

apt install i3-wm xinit 
don't pull it.

so we assume that the majority use a display manager who cares about this via 
polkit or similar.
x11 as root by default is a security risk to which all those running i3-wm 
under xinit are unnecessarily exposed.
unless they know what they are doing.

At this point I have to ask: Is my problem reproducible?

I find it problematic that if you run startx (i3-wm) as user at tty xorg still 
run as root by default.

graphic driver is nvidia.
secureboot is activated with mok (debian default key).

what makes you think it's different with e.g. amdgpu?

You linked to the Archlinux Wiki and I have installed i3-wm under archlinux and 
there X11 runs without root privileges by default.

I assumed that it is the same under Debian because Debian is known for having 
relatively safe default values.
It looks like i3 doesn't need x11 as root either.

Debian bookworm rc4 without gnome, just default system tools and after reboot i 
just run at tty:

sudo apt install i3-wm alacritty xinit xserver-xorg
echo "exec i3" > ~/.xinitrc
startx

and xorg running as root

Re: Re: X11 should not run as root or?

You linked to the Archlinux Wiki and I have installed i3-wm under archlinux and 
there X11 runs without root privileges by default.

I assumed that it is the same under Debian because Debian is known for having 
relatively safe default values.
It looks like i3 doesn't need x11 as root either.

X11 should not run as root or?

[therealcyclist]

I tried the new Debian bookworm installer rc4 and i manually installed i3-wm.
I started i3 from tty with startx command as user.
to my surprise i found out that the xorg process is running as root.
that can't be intentional, can it?

I have fixed the problem by adding the following line in 
/etc/X11/Xwrapper.config 

needs_root_rights = no

After that xorg runs as user.
