Yes I found it in my /etc/lazarus.
I did a test again and this are the steps and result:
01. Tested on my Ubuntu Mate 16.10 64-bit.
02. I deleted both my "
/etc/lazarus" and "
/home/handoko/.lazarus" folders.
03. Started my Lazarus 1.6.4 and quit.
04. Lazarus 1.6.4 created the missing configuration files automatically.
05. But Lazarus 1.6.4 didn't create "
/etc/lazarus".
06. I uninstall Lazarus 1.6.4 (also FPC, FPC-source).
07. I deleted my "
/home/handoko/.lazarus".
08. I installed Lazarus 1.8.0RC2 using deb files.
09. Started Lazarus 1.8.0RC2 and quit.
10. Lazarus 1.8.0RC2 created the missing configuration files automatically (See #4)
11. Lazarus 1.8.0RC2 created "
/etc/lazarus/editoroptions.xml" (See #5)
12. Lazarus 1.8.0RC2 did not use DejaVu Sans Mono font.
13. I exited Lazarus 1.8.0RC2.
14. I deleted both my "
/etc/lazarus" and "
/home/handoko/.lazarus" folders.
15. I started 1.8.0RC2 again.
16. Lazarus 1.8.0RC2 created the missing configuration files automatically (See #10)
17. Lazarus 1.8.0RC2
did not created "
/etc/lazarus" (See #11)
18. Lazarus 1.8.0RC2 now use DejaVu Sans Mono font (See #12)
Isn't it strange?
Edit:
My problem has solved, but the bug is still there. Also the Gtk input issue still not fixed.
