Bug 1421419

Same results on other (larger) monitor.
So we must conclude that on VIA Epia M910 the installaer launches into an unusable video mode whatever we do.
The text install mode does not allow for customization of a disk layout so we can not install Fedora. (not even a simple LVM based one...)

Yes we cannot install Fedora:
The other options are via the network but what gibberish are the network interfaces named as instead of eth0 and eth1?
What to boot them with?
Oh, xhost is mentioned but nothing about a possible firewall?
No ssh is used? (did not get there as the installer assumes dhcp and cannot find eth0 and thus bombs out)
So I see multiple issues here.
textmode install is way too limited
graphical mode does not work
network mode is unclear to set up or even to explain how it should function
How to report them?

It is possible to configure partitioning via kickstart (check part, volgroup & logvol commands):

Also if a correct resolution for your monitor is rejected by the system then there is probably something wrong with the video drivers, not really with Anaconda (if I understand the issue correctly).

Hello,

The first monitor as a 1280x1024 one with LCD.
Tried forcing that resolution.
Then I tried the 1680x1050 one.
Same deal.
So it may be the video driver.

This is the hardware:
00:01.0 VGA compatible controller: VIA Technologies, Inc. VX900 Graphics [Chrome9 HD]

Both monitors were connected via VGA.

OK, so I'm reassigning this bug to the openchrome video driver component, as I guess that's what's probably being used on your device.

Please reassign accordingly if my assumption is wrong. :)

I guess there's not much I can do at this point, unless you can install in text mode with the default disk layout and then get an Xorg log.
Or install to another computer then move the disk to the VIA board. Basically, anything that would allow to get an Xorg log will help.

If that's not possible for whatever reason, let's wait for Fedora 26 Alpha release, which will have openchrome 0.6.0 (while F25 installer has 0.5.0).
Another possibility is to try with Fedora 24, which has 0.4.0 for the installer and 0.5.0 in the updates.

Text mode is too limited.
Default disk layout is not acceptable.
You imply that you cannot reproduce this.
Can you please confirm?
How then did I find two monitors that drive the driver into confusion?
I went ahead and installed using the vnc method.
But I can boot the DVD anytime and see where the xorg log is in that situation.
Can you please clarify?

It is very likely a driver bug. I can not reproduce as I don't have the very same  hardware. I do have a bunch of VIA boards, with various IGPs flavors, ranging from the older CLE266 to the more recent VX900, but no Epia M910. The VX900 I own is actually a laptop, so the primary display is not VGA. I'll try to start a new install on it to see if I can reproduce, but this will not be conclusive, as again, this is not the same hardware.

There's no way for me to at least start to diagnose the issue with just a description of what is happening, I need an Xorg log. My assumption is openchrome will behave the same from Anaconda and from a running OS. That's why I suggested several ways to get Fedora installed in order to get an Xorg log. I understand you need to use a non-default disk layout, but this is orthogonal to the display issue. First let's try to diagnose then fix the display issue, then you will be able to re-install. And anyway, there's no way to get what's on the DVD fixed, so that'll just help for upcoming Fedora 26.
Hopefully that explains better what I am trying to achieve.

Also, why are you adding resolution=1280x1024 to the kernel parameters ? What happens if you don't ? Is there a different behavior with and without it ?

Reading your comment again, I understand you did manage to get F25 installed with VNC, which was not obvious at first. Does X works now ?

The proposal is to boot the F25 dvd again without destroying the installed system to get hold of a xorg.log.

I did try appending resolutions. No change.
I do and di not run X on the box and those itejms might have gotten updates since installing.
So booting the DVD and getting a xorg.log appears to be the choice.

If I do that, where is the log on the filesystem?

According to https://fedoraproject.org/wiki/Anaconda/Logging#Anaconda_logs_on_the_running_system the X log should be in /tmp/X.log during the install then copied to /var/log/anaconda.xlog after the installation is finished.

xorg.log

The xorg log  does not have clues as far as I can see.

Yup, no clue in the log, it looks fine... Not a monitor detection issue, likely something else. I would need a dump of the registers values, but that is likely not practical to achieve from Anaconda I guess. I'll make some tests to see if that is even possible at all.

How did the display looked like when running the installer ? Any chance you can take a picture ? That could bring some light. Remote debugging a video driver is kind of a difficult task.

Btw, you did not answer the question, is X working now ? I mean outside of anaconda, from the regular OS ? If not, I'll provide a version 0.6.0 of the driver for you to test. I have not built it for F25 yet, I'm chasing a regression with upstream at the moment.

xorg log from f25 install

I installed some extra rpms to get startx working; this is the log from that attempt.
