Some 15.04 annoyances...

Interesting: On my system (15.04, updated, nVidia-346-updates, EVGA GTX 780) I get this warning "EGL is not supported by all OpenGL drivers. If not supported the Compositor will be disabled." when I attempt to select EGL, and indeed if selected - I lose desktop effects.

EDIT: EGL is not supported by nVidia's implementation of OpenGL.

Yes, I'm also using Nvidia.

Probably not surprising, same experience with an Nvidia card using the Nouveau driver.

I've done a bit more reading and it seems EGL is supported, but not within X11. Wayland or Mir it works. It's kinda a complicated issue and I'm not taking the time to dig deeper. GLX w/OpenGL 3.1 works fine here.

I have the same issue with Conky disappearing on my 15.04 VirtualBox guest. There are minimal if any desktop effects enabled, and the compositor is enabled.

Originally, kdesu was the thing to use, but by 7.10 Gutsy Gibbon kdesudo (created by Kubuntu) was introduced to better handle things.

With Intel graphics (HD 5500), OpenGL 3.1 with EGL is working fine -- effects are rendering as expected.

For all to know with Conky I seemed to have fixed it. I changed own_window_type from normal to override. So far so good and not odd issues from that!

This makes conky appear on top of all windows. If you are using something like an image manipulation or editing program, everything underneath the conky will not be usable. So no good for anyone running windows full screen or multiple windows on one desktop. Still looking!

[MoonRise]

Hmmm....That's not how that is acting here. It's on all desktops but subsequent window, i.e. Dolphin, GIMP, etc. all are on top of it. No interference from it.


EDIT: here is all that is said from the Conky site:

Override windows are not under the control of the window manager

[timgood]

It seems you are correct! Will give this a try. At first glance, it does seem to be working. Strange, when I tried this setting before, it remained on top of all windows. Thanks for this.

Well, I played around some more and found what it does do that would interfere with the Wallpaper. I didn't notice because of how I have my wallpaper currently to keep the background behind Conky Dark. With Override Conky appears to not allow Transparency. So, if your wallpaper covers the entire desktop, Conky will have a black background that covers the portion of wallpaper it resides. No biggie at the moment for me due to current wallpaper, but.... well enough said. For now I'm OK and not annoyed with the disappearing/reappearing act.

[timgood]

Funny, I have full transparency and no disappearing. My window settings within conky are:

[FONT=Ubuntu Mono]# Window specifications #[/FONT]
own_window_class Conky
own_window yes
own_window_type conky
own_window_type override
own_window_transparent yes
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
own_window_argb_visual yes

No black background on any wallpaper.

[MoonRise]

I'll try what you have. Let you know.

EDIT: That didn't work but I also noticed you have own_window_type twice so one is taking precedence, maybe? Either way I'm fine with my current set-up so no harm no foul.

What makes you think that SDDM is the cause of the black screen?

Kubuntu won't return to LightDM. SDDM is the default display manager for KDE now, and since Kubuntu strives to be as close to KDE's defaults as possible, it'll be the one we use now.

I never said explicitly that SDDM was the source of this, I'm just saying there have been issues with SDDM and I *feel* it has not been a very well thought out choice. I also didn't say *Kubuntu* was the source of that choice or I would not have said "they" ;-). I never thought Kubuntu would be willing to make such a deviating choice or that it even was possible. Nevertheless it would make an extremely strong signal if you did just that, but I don't know enough about the display manager stack to be able to elucidate.. *I am willing to find out though*. Or at least I am wanting to since I want to be able to debug plasma issues.

Plasma is ionized gas, I think it is funky ;-).
