It's important to keep your driver and software updated.

tbs-open-linux-driver swipes Ubuntu 20.04 graphics driver

Postby hsmptg » Sun Apr 11, 2021 7:14 pm

Hi

I was trying to install the driver of a TBS6982 on a fresh Ubuntu 20.04 (kernel 5.8.0-48-generic) running on a PC having a i7-4790K CPU with Intel Integrated Graphics Controller (i915).

I used the TBS Open Source Linux Driver Offline Package v20210204 and in the end I had success:
Code: Select All Code
helio@hercules:~$ dmesg | grep frontend
[    2.985229] SAA716x Budget 0000:03:00.0: DVB: registering adapter 0 frontend 0 (TurboSight TBS 6982SE DVB-S/S2)...
[    3.291713] SAA716x Budget 0000:03:00.0: DVB: registering adapter 1 frontend 0 (TurboSight TBS 6982SE DVB-S/S2)...


I confirmed that the driver was working, since it is recognised on a TVHeadend server I installed next.

The problem is that prior to the driver installation I had a fully functioning graphics driver as can be seen on the following commands:
Code: Select All Code
helio@hercules:~$ inxi -G --display

helio@hercules:~$ lsmod | grep i915

But after the driver installation I lost the i915 driver:

helio@hercules:~$ inxi -G --display

helio@hercules:~$ lsmod | grep i915
(nothing)


Without this i915 driver, Ubuntu uses a generic one that has no full HD support.
I tried to reinstall the missing i915 but never had any success.
Can anyone give me a tip on what to do?

Hi
Just to inform that tbs-open-linux-drivers_v20210204 with Ubuntu 18.04 do not cause the problem I reported in my initial post.
So I will use Ubuntu 18.04 until someone find a solution.

Yes, I can confirm that bug. :(

First I thought I was wrong, but then I tried it under the previous kernel (which I selected in GRUB2).

Have Ubuntu 20.04, media_build-2021-02-04.tar.bz2 and Kernel 5.8.0-45-generic and 5.8.0-48-generic

I cannot set the LCD brightness any more.

Update:

Code: Select All Code
sudo rm -rf /lib/modules/`uname -r`/kernel/drivers/media/
does NOT help here.

I fear some energy savings have been disabled, the CPU is now much hotter ...

Yesterday kernel 5.8.0-49-generic was installed, the graphics card driver does now work again.

In case I want to use a TBS product, I need to boot with the previous kernel (select 5.8.0-48-generic in GRUB2).

The break has occurred between Ubuntu kernels 5.8.0-44-generic and 5.8.0-45-generic.

If I re-install kernel 5.8.0-44-generic and compile tbs-open-linux-drivers_v20210204 then both the TBS drivers and video drivers (ast) load correctly.

As soon as I install any kernel > 5.8.0-44-generic then the tbs drivers load but video drivers fails with following errors:

There is a breaking change at kernel 5.8.0-45-generic that needs an update - please investigate.

Support have stated it is best to lock at a known good working kernel (not ideal but it works):

"If both tbs driver and graphics drivers both works fine in kernel 5.8.0-44, please downgrade to 5.8.0-44 and use it.

Maybe it relates to kernel, maybe it's the conflict of 2 drivers. Currently, does not have a good solution for this.
When you downgrade to 5.8.0-44, please run the following cmd to hold this kernel:
# apt-mark hold linux-image-generic linux-headers-generic

for kernel, no need to upgrade frequently, and normally, the defaul is the best."

Hi Steven,

I have the same problem that those who posted above,namely,once the dvb drivers are installed on ubuntu 20.04,and working fine,the resolution changed from 1920x1080 to 1280x768. I managed with difficulty,after an upgrade to the graphics card,to return to the initial resolution,but now Ubuntu sees cards but without drivers.Now I'm afraid to reinstall them,so that the same problem with the resolution does not return,as the first time.
I have to say that two times I reinstalled Ubuntu 20.04 version,believing that I made a mistake somewhere in the process of installing the tbs drivers.Unfortunately I did not manage to solve the problem. For now I have the correct monitor resolution but without the tbs drivers installed.What do you think I should do,to wait until a forum colleague comes up with a solution to the reported problem or go back to unbuntu 18.04,when everything was working fine?
Here is Ubuntu 20.04 (kerner5.8.0-50) with tbs cards.
Regards

Because I could not install the drivers for ubuntu 20.04 without the risk of a wrong resolution for my monitor, after many attempts, even with version 5.8.0-55,with the same disastrous results,I went back to version 18.04. Installing the drivers for cards tbs went well and works.
Actually which of the kerner versions is valid for tbs cards on ubuntu 20.04?
Thanks.
