I downloaded and tested the Testing version and both DVD and CD versions present me with a black screen when I try to install graphically. I can install without the graphical environment.
Can somebody else confirm this? I did "md5sum -c md5sum.txt" and everything is OK.

I don't know Debian, but if you could tell us what the hardware is it might be helpful getting a good answer.

Since it is 'Testing' you can expect things to break.
That is what testing is for.. to find out what breaks.

It's not hardware related =) Trust me. Every other Debian ISO works. This could be just a little bug.

No. I expect more things to break at Unstable or experimental. But I don't need those images so I didn't bother to download them.

It might be driver related, so the hardware indeed matters.

Tested on VirtualBox, my machine and a friend's laptop. This last one being very new hardware.

I'm hoping other people can confirm this. Even the little CD image has this, so if someone has a good connection, please feel free to try it too.

I doubt many Debian testing users would ever notice that the graphical install option was not working. I, for instance, can't understand why anyone uses it.

As pointed out this is testing.

If you want to use testing as testing then you should be reporting this as a bug so the devs know about it. It is possible that it only affects your hardware. How are they supposed to fix it if you don't report it.

The installer has to evolve along with the rest of the new release. Falling behind can only make it harder to fix later.

If you want to install testing to simply use, I think you will find most folks use the Debian stable netinstall image (works reliably) using just the base install. Upgrade that install to testing or sid and then finish installing the OS.

I am sorry to burst your bubble but that installer is not the installer used for Debian stable. You have no idea what the cause is and hardware bugs are extremely frequent in any testing environment.

Could be very specific to your hardware even. Could be specific to any neccessary component.

You and I are not qualified to make this judgement. Only a properly filed bug will give the folks that actually know something of the installer for Jessie will get this analized.

Testing is NOT unstable and it is way more reliable to install from the Testing ISO, I tried many times upgrading from Stable and it's just a mess.

Again, I tested with 3 hardware specs, the last one being the newest. It happened in all of them.

I'm going to zero this drive and in the meantime search for the bugtracker.


What bubble? Did you really think I thought this installer was for the Stable release? I clearly stated that this is the testing ISO.

Bugs are extremely frequent in testing? You seem to know little about Debian. Ubuntu LTS is mostly based of Debian Testing, and it's very stable and rare to find broken things.

You are correct, testing is not unstable but it isn't stable either.

Do you think Ubuntu take Debian Testing and just slap their pictures into it?
No they do further patching..

If you are a 'serious' Tester then
http://www.debian.org/Bugs/Reporting

remember you must provide specific details

is pretty much useless.

if you want to just use testing, install wheezy.. then

but you said yourself, the text based install works.. why do you need the graphical install?
I could understand if it was "stable" we were discussing, but no were are talking about _*testing*_ which is not stable...

Sorry I had to step out for a while... looks like this turned into a testing vs stable discussion while I was gone!

That was my thought. I mostly hang out in the Slackware forums and most of the "blank screen" posts I see there are related to kernel support for the latest hardware during install and boot, so I thought it might be helpful to know the hardware.

Being a Slacker I am accustomed to -current (i.e., testing) being nearly as stable as the latest release, but not sure about Debian so I'll stay clear of that discussion.

You might want to tone down your bullshit a bit.
It's very clear you have little idea what you are talking about, and lecturing users with a lot more experience than yourself is unlikely to get you any useful help, now or in the future.

Well, in VirtualBox it 'falls over' when initialising the framebuffer

text mode works

You are familiar with Ubuntu, so therefore, you know more about Debian than Debian users do? Impeccable logic. And how rare are bugs in Ubuntu? I remember Buntu having quite a few annoying bugs when I used it.

That is probably the case, but breakage is also part of a testing system.

People, please keep this discussion civil.
To clarify some things:
- Debian Testing is currently not in a freeze, so the installers for Testing and Unstable are the same.
- Since the OP seems to have tested this on different hardware and in a VM this may indeed be a bug, so the proper way is to just report it.
- While Debian Testing is indeed pretty stable it is still a development branch and therefore can have bugs and/or instabilities, especially when it comes to the installer, that is naturally less tested than the rest of the OS.
- When opening a new thread it is a always a good idea to put in all information that might be necessary to help, even if you deem it at the moment to be superfluous. It may help to answer your question even if you don't think so. At this time we don't even know if you use the 32 or 64 bit version.

FWIW, I just tested the 64 bit netinstall ISO in Qemu and it works.
