lxterminal assertion failed

[andyj]

I finally got around to running tce-update and now I get this trying to run lxterminal:

Segmentation fault

What would have broken this? Do we need a gtk3 and/or lxterminal rebuild?

[Juanito]

lxterminal-0.20 is old (2014) and both vte and gtk3 have been updated many times since then - I'll take a look.

[Juanito]

I tried recompiling lxterminal and using a more recent version of vte-2.90, but the error remains.

I see debian uses lxterminal and vte compiled against gtk2 rather than gtk3 - perhaps this is a solution until lxterminal releases an update or perhaps the github version of lxterminal will work?

Otherwise, there's gnome-terminal...

[Juanito]

got it - the github version of lxterminal will compile against the latest vte (as opposed to vte-2.90), which fixes the segfault.

The warnings remain, but don't seem to be a problem.

Now it opens, but I get this with alsa:

tc@box:~$ alsamixer
Error opening terminal: xterm-256color.

Do I need a link somewhere? Which xterm returns nothing.

Also, lxterminal now has a "feature". When I resize the window to make it taller OR shorter, it gets narrower. At least I can widen it afterwards.

loading ncurses-terminfo fixes this - comment added to info file

Oops - forgot the wrapper script, extension re-posted

I see the same with flwm - a bug in flwm, lxterminal or vte?

[patrikg]

Some circumstances you could setting another terminal to support the program.
I do it this like these two ways:
export TERM=xterm
export TERM=linux

[andyj]

The apps browser needs the wrapper script. We've been down that road already. The resizing thing doesn't affect aterm. Lilyterm segfaults, so I can't say about that. I am using flwm_topside in a VMware VM, using open-vm-tools (trying to get 10.1 ready for submission which is how all this started) on a Slackware 14.2 host using the open source radeon driver. Everything is 64 bit. It "could" be a video driver quirk somewhere in the stack, but right now I don't know of anything else having issues.

Is ncurses-terminfo a dependency or a "nice to have?". Dejavu-fonts-ttf deserves a mention in the info file as well. Without it whatever fonts lxterminal uses by default look kinda rough.

It only seems to be needed for lxterminal to display alsamixer, but there may be others - note that only xterm-256color is used for this

Dejavu-fonts-ttf deserves a mention in the info file as well. Without it whatever fonts lxterminal uses by default look kinda rough.

The info file already says "Optional deps:  More font TCZs, load fontconfig then load lxterminal"

[andyj]

Sorry I haven't looked at the info file in a while    I did notice though that while in an lxterminal window I loaded dejavu-fonts-ttf and started another lxterminal from the first and the fonts improved immediately, so it seems to "prefer" different fonts.
