Xpresent transparent window title bar
New member of this mailing list. I've been using Windows 7 side by side with Linux (mostly Ubuntu MATE). I'd like to use a couple of the features from the Aero interface from Windows 7 on MATE I've been discussing this topic on the Ubuntu MATE community forum here: https://ubuntu-mate.community/t/marco-xpresent-compositor-transparent-title-bars/26968/4 In brief, I'm trying to get semi-transparent task bar (accomplished), inactive window background (accomplished) and window titlebars (not yet accomplished with Xpresent.) All of these features are achievable with Compiz, but that consumes quite a bit of the CPU, so I'm seeing if I can accomplish this with something less resource-intensive, like Xpresent or Xrender. As noted, with Xpresent, I haven't been able to achieve the semi-transparent titlebars. Is there any known way to get semi-transparent titlebars with Xpresent? I'm looking at the /usr/share/themes/YaruOk/gtk-3.0/gtk.css file and trying to figure out how I might modify the titlebar rendering in that theme, but the code is difficult to decipher by someone not familiar with it. Thanks. If this is not easily achievable, I'll switch my focus to Xrender. -- Guy Rouillier
Re: Xpresent transparent window title bar
I originally sent this message, and subscribed to receive replies. Carsten Haitzler appears to have replied to this message in a mirror, with a cc to xorg@lists.x.org. I did not receive that reply. I'm guessing that subscribers only get messages sent "to" the list, and not "cc" the list? Carsten's full reply is here: https://lists.x.org/archives/xorg/2024-February/061540.html I don't now the proper protocol for copying text from other messages, but I wanted to respond to the opening comment: > Your question really should be directed at the mate picom etc. developers, not > here unless you want to discuss the general x11 compositing and rendering > pipeline etc. .. so I'll answer from that point of view. I believe that the Xpresent extension is not part of picom. Instead, it is part of xorg itself: https://gitlab.freedesktop.org/xorg/lib/libxpresent I was informed of this when I initially asked on the Ubuntu MATE forum: https://ubuntu-mate.community/t/marco-xpresent-compositor-transparent-title-bars/26968 Since Xpresent is not a compositor, I'm going to spend a little time seeing if I can figure out how to modify the theme I'm using (YaruOK) to have transparent title bars. If I can't get that to work, I'll switch to Xrender (which definitely is part of picom, and is a proper compositor.) -- Guy Rouillier
Re: Window id of xterm started
I haven't tried this myself, but perhaps it works. I found the following via Google by searching for "window id from pid": https://stackoverflow.com/questions/2250757/is-there-a-linux-command-to-determine-the-window-ids-associated-with-a-given-pro I then searched to see if you can get the pid of a process started in xinitrc, and found this: https://bbs.archlinux.org/viewtopic.php?id=104145 -- Guy Rouillier On 2/10/2024 7:53:39 AM, "Riza Dindir" wrote: Hello, I am starting xterm in my xinitrc.

I've been using Ubuntu MATE and Linux Mint MATE for years without an xorg.conf (and many years before that with an xorg.conf.) I don't remember when the conf file became optional. I've been able to get the multi-monitor set up I want by using the GUI desktop configuration tools. -- Guy Rouillier
