I am trying to do a blindscan and it says there is no signal on the channels. I have to scan the transponder manually. Can you please help?

ptergrand · Sep 22, 2023

How can I make the values in the image smaller?

The monitor is small and does not fit on the screen....

3dB is a very low signal. In most cases it is not even possible to lock a signal then, but if it is possible, the blindscan code
may consider the signal to be too low (otherwise it will react to too many false peaks)

Like I wrote earlier: you have to adjust your screen resolution in linux (e.g. 1920x1080 or larger) and/or
reduce your font size and/or adjust your screen dpi. How to do do that depends on what type of linux you are using.
Usually it should be somewhere in settings/display or settings/monitor.

The program is made for "normal sized" displays

I adjust the screen resolution this way. The screen becomes smaller. The text appears very small in the font.

star@star-Vostro-3670:~$ cvt 1400 1050 59.98

Thank you very much for your program.
Is there any new development in your program?

ptergrand · Sep 23, 2023

star@star-Vostro-3670:~$ uname -a

Do I need to upgrade the kernel version?

Well if the font size is too small, then increase it. The program follows the user preferences (to some degree)

Yes, from time to time. There will be a new release within a few weeks time.

Hi

New Fedora kernel update (to 6.5.5-200), new modifications to add to the code for the blindscan drivers.
Here are my two modifications:

In ~/blindscan_kernel/media_build/v4l/compat.h

change return get_user_pages(start, nr_pages, gup_flags, pages, vmas); to

#if LINUX_VERSION_CODE <= KERNEL_VERSION(6, 5, 0)
return get_user_pages(start, nr_pages, gup_flags, pages, vmas);
#else
return get_user_pages(start, nr_pages, gup_flags, pages);
#endif

In ~/blindscan_kernel/media/drivers/media/v4l2-core/videobuf-dma-sg.c

change

err = pin_user_pages(data & PAGE_MASK, dma->nr_pages, gup_flags,
dma->pages, NULL);

to

#if LINUX_VERSION_CODE <= KERNEL_VERSION(6, 5, 0)
err = pin_user_pages(data & PAGE_MASK, dma->nr_pages, gup_flags,
dma->pages, NULL);
#else
err = pin_user_pages(data & PAGE_MASK, dma->nr_pages, gup_flags,
dma->pages);
#endif

It works for me, I don't know if it's the best way of doing it or not.

deeptho · Sep 28, 2023

Thanks. Typically such changes end up in the tbs version of media and then later in blindscan drivers.
The way you propose (with ifdef's) is at odds with the media_build approach. The general approach there
is to always the code for the latest supported version in media/ and then create patches in media-build/ to modify that
code for earlier versions. It is of course a bit complicated (and error prone - major problem) but I suppose it results in cleaner
code.

In general I would advise keeping older kernels (and kernel devel packages) unless there is a strong reason to change.
Even that is not made easy...

I am totally new using Linux OS of any type. I'm Trying to install neumodvb Prerequisite;

sudo apt install -y clang clang-tools libtool libboost-program-options libboost libboost-regex libboost-context \

Use Synaptic Package Manager to install most of your missing dependencies.

I notice you are installing from the Debian list, which doesn't have some of the installs needed for Ubuntu 22.04. It was my first attempt at converting Fedora to Ubuntu dependencies (suffixes are .dev instead of .devel) and is somewhat outdated now, although some are installable.

Scroll further down to the 22.04 list and install those. ( liblog4cxx file is included in the liblog4cxx-dev package, and won't appear as an installable dependency).

I did also use the Ubuntu 22.04 files, but in the end, I don't see the TBS6903X or any devices listed on opening the application.

I will like to start installation all over again, but how do I uninstall all the previously installed packages?

Why do people always want to "fix" things by uninstalling? It is like demolishing your house when
you can't find the front door keys.

If the device is not listed, you probably have not installed the drivers.
It is explained here.
