How to use a different UI font?


I have made a new CafeTran installation, because the latest Java version was not showing up even after re-applying the update.

I have directly noticed a difference in the UI font used.

The UI rolled back to the default Verdana (so did all other font elements [in View > Fonts]), while I was using the Ubuntu (regular) font, which is set as the default font in my Ubuntu installation.

It is as if CafeTran stopped picking/finding my current font.

In /etc/environment, this is the line that I had added before:


With the new installation, how can I set the UI font back to Ubuntu?


I use the GTK LAF.

Hi Jean,  

On a side note, what distro of Linux do you prefer/use? I have a bit of free time on my hands ;-)


Hi Michael,

I am using Regolith: (Ubuntu-based, using the i3 window manager).

Interesting thanks!


On Ubunut 19.10, CafeTran running on the embedded Java with GTK theme can pick the system UI font. You can check it with Tweaks application. For example, changing the size of Interface Text affects some GTK components in CafeTran as well.

Hi guys,n LXwith the LXQt desktop, and

View > Font > Project, memories and resources

(with GTK Look and feel)

does nothing. The fonts are way too small and cannot be changed at all. In fact, most Font settings seem to not work. What am I doing wrong?

I am just installing the Gnome desktop, to see if things work better then.

Christ almighty, now I remember why I recommend people use Windows. What a nightmare just trying to get basic stuff to work. Think I will abort my adventure and get back to work in Win10, with my six million Windows programs that just work. Maybe when I retire and have loads of time, as I do like to tinker but when I need to get work done it just isn't cost effective to use Linux.

Sorry Jean, I know you like and use it, but I suspect you are a tad more technically minded than I am. I can just about manage an AutoHotkey script ;-)

Hi guys, I'm currently playing around with Lubuntu, with the LXQt desktop, and

Migrating to another OS is not a weekend project, you can't expect things to work exactly as with the OS you are most comfortable with.

It's not that I am particularly technically inclined, but I use GNU/Linux exclusively for many years, and would not have it any other way. Returning to Windows or MacOS is out of the question.

Regolith and its tiling window manager is one the biggest changes and happies surprises in my GNU/Linux experience. It so much more keyboard friendly, resource efficient and intuitive once you get to know it. I even ditched my dual external displays, since it's so easy to navigate between windows and workplaces. I'm typing this from bed. It's just that efficient. But yeah, it's definitely not for the Linux neophyte, although it offers sane defaults and makes it easy for the more experienced user to jump on the i3wm train.

With your own requirements as I understand them, I indeed don't see any reason to attempt such a migration to Linux.Likewise, it did not make sense to buy a low performance silent laptop since you rely so heavily on querying huge TMs/glossaries. By the way, if everything just works, why keep tinkering with so many CAT tools and different setups? It seems to be quite counter-productive.

Perfect is the enemy of good…

@Igor, thank you for confirming CafeTran does pickup the system UI theme with the GTK LAF.

Yes, I use the built-in Java version and have se the Ubuntu font via the Tweaks application.

It seems the Ubuntu font is being used for the UI, I did not recognize it because it is bigger but thinner. Tweaking the different font sizes makes this work.

I may attach a before/after screenshot later on.

@Jean: Ha ha, yeah, the silent laptop was an experiment, mainly caused by working at night a lot with my previous Dell Precision (M6800), whose fans just wouldn't shut up, ever. So I swung wildly in the opposite direction, and thought I'd try to get a 100% fanless system. I tried it, and in the end – of course – it wasn't powerful enough, for me at least. Oh well, lesson learned. My new Dell Precision (7740: i9, 64GB RAM, Samsung pro SSDs, etc.) is a little less noisy (fan-wise, but does have coil whine), but I now no longer mind a bit of noise, especially since I get oodles of power in return.

@Igor: Guess, what, so am back in Windows 10, and I still can't change the font size of the Matchboard. :-) Am I missing something?

This should have effect right after you refresh the grid (e.g going to the next/previous segment).

Linux Ubuntu-based operating systems with LibreOffice on board are a good start. Your initial reaction is typical, but letting keep both Windows and Linux for some longer period, you will notice visiting the Linux side more and more frequently. :)

It is set via View > Font > Notepad and text areas. You need to restart after the change. Probably, it should be renamed to be more intuitive in a future update.
