there is no module at kernel

https://linuxtv.org/wiki/index.php/DVBSKY_S952

try this


sudo nano /etc/modeprobe.d/cx23885.conf

put inside as from this list card 50 https://linuxtv.org/downloads/v4l-dvb-apis/v4l-drivers/cx23885-cardlist.html


options cx23885 card=50 
options CORE_cx23885[0]_dvb adapter_nr=0

next line is from this manual
https://ubuntuforums.org/showthread.php?t=1648472 try without it

Maybe it's due to many installation attempts ?

Below my home folder, I think that I should remove "media_build"

Update kernel, this will destroy modifications.

Update karnel finished for me no good :)... boot screen displayed a kernel panic message, so I decided install new ubuntu instance

After installation I executed command dmesg |egrep "cx23885|cx25840|dvb|frontend"

I didn't install any drivers/patches, anything related with this DVBSky S952 card....
For me it's very strange.....

After instaling TVheadend, I executed command

There some issue with "Direct firmware load for dvb-demod-m88ds3103.fw failed with error -2"

Easy to solve


sudo wget -O /lib/firmware/dvb-demod-m88ds3103.fw https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-demod-m88ds3103.fw

Now, the DVBs tuner gone :(, when I execute "dmesg |egrep "cx23885|cx25840|dvb|frontend" I received empty answer

Maybe the reason is that my card is "DVB-S2 Mystique SaTiX-S2 Sky Xpress DUAL" it's a clone DVBSky S952.
Previously, I used this card on Windows 10 + DVBViewer, and everything worked well ...obviously with DVBSky S952 drivers.

Restart and post complete dmesg
for example in http://paste.ubuntu.com/

Before I collect complete dmesg I executed once again "dmesg |egrep "cx23885|cx25840|dvb|frontend" and .....

if not using this realtek usb wifi remove it
also if audio card not used stop it
There is in CPU video and Nvidia 8400/8500

disable CPU video

there is newer bios for your mobo also

KenyBDG K.

unfortunately, this computer is 300km away, so remote update BIOS is not possible, also I don't know how to remove or switch off CPU Video, Audio

Saen Acro

In BIOS ;)

KenyBDG K.

hehe I know that I can do it in BIOS :) but I asked about how to switch off from the ubuntu level ? :) the same as it can be done in Windows

Saen Acro

Haha even in windows cannot turn off device, you can "blacklist it".

Only on oldest Toshiba laptops can be done.

That's why there is a KVM/IPMI/AMT modules on server mobo's.

KenyBDG K.

Do you think that the devices mentioned in previous post can cause problems with the DVB-S card?

Saen Acro

Not 100% sure but its recommended to disable sound card com/printer ports and any non used devices.

KenyBDG K.

No Audio
No Wifi
No GPU on CPU

Fast question: Why adapters is+not enabled+ on pictures?

Make revision of configuration in TVH

is dvb network attached to adapter and is adapter enabled

Probably firmware problem, use this with is distributed by DVBSky

is this device use USB tuners?

seelsusb

hint.
tree /dev/dvb
is better command then
ls /dev/dvb
