LightDM

[falldown]

I wanted to post this here in our section so that we could all try to solve this.

I have installed VSIDO several times (old and new images) and I get the same rainbow screen at login..

similar to this.

Now this goes away after I install my nvidia drivers (separate machines)
I searched the web for answers but have found nothing to resolve this.

What I am concerned about is that others might be getting the same result as I am.
In my opinion this is a HUGE turnoff when booting a new distro for the first time..
not to mention that some people are more comfortable with using the default graphics driver.

By no means am I saying anything negative about VSIDO or the amazing work you are doing VastOne.
I am using VSIDO as my main desktop.

I have seen this too, though never on the LiveCD portion.  I believe it is a cache that nVidia stores and impacts nouveau.  Like you, once I install the nVidia drivers the issue goes away.

I will continue to sort this one out...

Thanks for raising this topic

I use NVIDIA drivers as well.  I'm curious if someone using a different driver sees the same thing.
I've never thought about it.   But falldown is right.  It could be a turn off for some.

PS: Here waiting for the plumber again.

VastOne I haven't the slightest clue how one makes a distro, but I am assuming that the iso is a copy of an existing desktop.?.
Is it possible that the original desktop has nvidia driver installed? and if so could that be causing a conflict in nouveau when ran from different hardware?

[VastOne]

No, I only use nouveau drivers when building it which are the same standard/stock drivers for all of Debian.  It is not coming from the build or we would see it on every LiveCD boot and install.

I get the lightdm "garbage" too, to me it looks like a framebuffer issue. dont have it on my second pc which uses a onboard "graphiccard", its a minor "cosmetic" issue

[falldown]

Thank you dizzie.
I agree that it is a minor cosmetic issue, but gives that first impression. Which is important.

hmmm.  Never happened to me.  I've installed VSIDO appx 25 or 30 times...  I have the Optimus/hybrid graphics...  All my installs have been on the same machine though, so probably why I've never seen this issue...

[falldown]

Thanks Jed.. that kind of makes the issue more confusing.
I'm curious as to what is the trigger to the lightdm "garbage" (as dizzie described it) is?

[VastOne]

I think the best solution is to get rid of a background within lightdm and just have a bland black setting.  It may or may not eliminate the issue, as I do not think it is a lightdm problem

[falldown]

I have no clue what the culprit is VastOne.

I do know that it is not consistent on my test.
I use 2 machines.. both are similar nvidia cards and similar processors.
Both installs are original VSIDO.. no personal configs on either.
I get the scrambled lightDM background roughly 3 out of 4 boots.

Thanks falldown, I am not sure either and for the first time I did see the same thing on a LiveCD

I will track this down
