There are guides available. Search for ‘Linux kernel debugging’ or ‘Linux module debugging’, depending on which you are more interested in. And, of course, learn about the relevant parts of the kernel.

You might have a look at Debugging kernel and modules via gdb¶. The kernel.org site has a wealth of information.

What happened to “A rising tide lifts all boats”?

They may accept the ongoing cost, but that doesn’t make it free. There may be no cash payment, but that doesn’t make it free. Cost comes in many forms. The glib misrepresentation of the transaction is disappointing.

It’s not free.

On Debian 12 and 13 with xfce, I am using ibus and Intelligent Pinyin (ibus-libpinyin) for Chinese and English. In the past I have used fcitx5 and various other IMEs. Once they’re configured there isn’t much difference between ibus and fcitx5, for my simple use. My Chinese is rudimentary but my Chinese wife is happy with the configuration. I switch input methods with a configurable keyboard shortcut (Ctrl-Space is my preference) or menu on the ibus item in the Status Tray Plugin of the xfce panel. Changing is easy.

I have task-chinese-s-desktop and task-chinese-t-desktop installed. These bring in fcitx5 and various fonts, which suggests that whoever created these tasks think fcitx5 is better than ibus. And I installed ibus-libpinyin, which brings in ibus. I don’t recall why now - it was long ago. So I have ibus and fcitx5 installed but have been using only ibus for the past few years. It works well enough that I haven’t revisited it. If I were installing again now, I might choose fcitx5 instead of ibus.

I see there are also task-japanese-desktop and task-korean-desktop, which you might find helpful.

I haven’t used 13/trixie but with 12/bookworm I use jmtpfs but it’s also available for trixie.
