How to use?

[tghelere]

I installed but I did not understand how to change the opacity. Nothing happens while trying ALT + scroll mouse.

[pbxqdown]

Basically you need to hover cursor on the window you would like to change opacity, holding ALT and scroll mouse to change opacity. Please attached the logs if you can not see the opacity change. Here is the command to view the logs:

journalctl /usr/bin/gnome-shell -f

I didn't find useful info. The extension is located at ~/.local/share/gnome-shell/extensions/transparent-window@pbxqdown.github.com. Try open extension.js, use the log code currently commented out, rerun(alt+f2 -> r) the gnome shell and see what is logged.

[lysist]

Same here, no reaction with ALT+scroll, repeated lots of times in terminal and syslog: Aug 14 20:18:35 user gnome-shell[1611]: JS WARNING: [/home/user/.local/share/gnome-shell/extensions/glassygnome@emiapwil/extension.js 365]: Too many arguments to function GLib.timeout_add: expected 3, got 4

[pbxqdown]

I'm not able to debug without log. Please provide your OS and GNOME version, uncomment the log statement, and see what is logged.

[lysist]

Thanks for the reply. I don't know how to open extension.js. This is Ubuntu 18.04.1 with gnome-shell 3.28, but in the meantime I'm back to Unity with Compiz since gs for me without transparency is hardly usable.

[pbxqdown]

@lysist , I think your environment should be fine, I'm also in Ubuntu 18.04 with GNOME 3.28, and I recently moved from Unity to Gnome because it looks better ;) Developing a Gnome extension is not hard, I suggest reading this article: https://wiki.gnome.org/Projects/GnomeShell/Extensions/StepByStepTutorial extension.js can be modified using a text editor, just uncomment the log code.

[lysist]

@pbxqdown, thanks for the link, and yes Gnome is not bad. I've managed to open the .js file, that was easy, sorry that I hadn't a clue in the first place. There is actually nothing serious logged. Unfortunately it doesn't take the text file to upload so I need to post the lines from log viewer all here and I've marked the relevant line.

Thanks for the log, the useful part is this:

Aug 16 09:46:00 gnome-shell[8892]: Hot key pressed
Aug 16 09:46:00 gnome-shell[8892]: 24
Aug 16 09:46:02 gnome-shell[8892]: Hot key pressed
Aug 16 09:46:02 gnome-shell[8892]: 16

According to this link: https://lazka.github.io/pgi-docs/Gdk-3.0/flags.html#Gdk.ModifierType.SUPER_MASK There are 5 types of mod key in gdk. For US keyboard layout, pressing Alt key usually generates MOD1(which is 8) and releasing it generates 0. However, when you press Alt it generates 24(which is combination of MOD1 and MOD2), and release it generates 16(MOD2). I guess you are using another type of keyboard layout.

The quick fix would be change this line: https://github.com/pbxqdown/gnome-shell-extension-transparent-window/blob/master/extension.js#L109 to:

case 24:

which will activate the succeeding process. Please let me know if this can fix the issue. If it works I will consider adding a config dialog letting users choosing hotkey themselves.

PS: According to this link: https://wiki.archlinux.org/index.php/Xmodmap You can find your correct key modifier for Alt key using the following command:

xmodmap -pm

[lysist]

@pbxqdown Wow, what a relief! case 24: worked and the mega clue is, it can be used for each window separately, awesome. Kudos to you and thanks a lot. btw. my keyboard layout is german.

[pbxqdown]

Great, glad it works :-) I will add a config dialog so users will not have to hack...

[lysist]

@pbxqdown a dialog would upgrade the tool a lot and make more people happy who miss ccsm I guess. btw. I've switched from ALT-key to SHIFT-key, because somehow chromium wouldn't recognize ALT+arrow left or right anymore to go back and forth with websites, instead it logged me out on ALT+arrow left and switched to console on ALT+arrow right. Your script helped me to find out which key is SHIFT, so it is helpful in many ways :-)

[pbxqdown]

I found that alt arrow bug too, seems like a existing bug: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1508146

[lysist]

@pbxqdown Thanks for the link, it's interesting and obviously tricky to research the cause. I've tried to repeat my case and switched the key again to ALT in your script in order to trigger the behaviour after restart of gnome-shell - but it didn't, everything works fine. Since I'm aware of this bug I'll leave the log code uncommented for a while, maybe it happens again and shows some useful output.

How to change the keyboard shortcut

[pbxqdown]

@moisestohias Try to set it in settings page by key press. If it doesn't work then you can manually set the number. Alt key has key code 8
