Upgraded again to Ascii.

First deleted ~/.Xauthority, disabled a line of script i had put in /etc/X11/Xsession , then rebooted and started a desktop via SliM
Desktop turned out to be in mode 1024x768.
I then changed my ~/.Xprofile, it turned out that i had to change 'VGA1' in 'VGA-1' in that file.
Re-enabled my line in /etc/X11/Xsession
Lo and behold, after restarting X the correct resolution was activated!!

The only thing left to do now is to make a xorg.conf file because X isn't capable of detecting my Intel driver.

Thanks for the given suggestions , got me searching in the right direction

You have X.org log files and the ~/.xsession-errors file to refer to.

Also once you run X as root you can break Xauth. It's often necessary to clear up any of these dotfiles, before attempting to startx again as a normal user.

For now there seems to be no real solution for this, so i went back to Jessie.
What i don't understand is why an older machine like my i386 upgraded smoothly?, no hitch whatsoever.

I'll keep looking for a real solution of course

Things changed in stretch. Thank Debian. IIRC it had something to do with wayland.

I'm not entirely sure as to why you're issuing startx as root? This is wrong irrespective of whether you're trying to run a rootless or setuid x.org. You need to stop doing that immediately if you want to troubleshoot this effectively.

The whole point of non setuid x.org is that it does not run the xserver as root (setuid xorg does), it's rootless.

Try issuing startx as a normal user. Remove stale ~/.Xauthority files if needed.

If you still get the same error, then it's possibly due to some legacy video driver and you might have to settle for running the older x.org with setuid root.

i965 is part of mesa/dri, it's not the kernel module, so that is in fact correct.

What exactly happens when you install elogind and libpam-elogind as it suggests and try to startx normally, rather than running the older xserver as setuid root??

I upgraded my other comp. (i386) from Jessie to Ascii, with no problems.
I tried (again) to upgrade my Intel i3, with no result, other then that SLIM failed to start X.

What i see in Xorg.0.log is that X is trying to use some driver called i965

[    20.577] (==) modeset(0): DPMS enabled
[    20.577] (II) modeset(0): [DRI2] Setup complete
[    20.577] (II) modeset(0): [DRI2]   DRI driver: i965
[    20.577] (II) modeset(0): [DRI2]   VDPAU driver: i965

While the kernel is talking about i915

[    5.054202] [drm] Initialized i915 1.6.0 20160919 for 0000:00:02.0 on minor 0
[    5.273640] fbcon: inteldrmfb (fb0) is primary device
[    5.334795] Console: switching to colour frame buffer device 128x48
[    5.352751] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device

Is it possible to correct this situation, so that X is using the correct driver (i915 i presume)?

Oké, thanks, i will try that one.
I have this old i386 machine, i will upgrade that one to experiment with

Well, you could try doing chmod u+s /usr/lib/xorg/Xorg if startx works after that there is something wrong with xserver-xorg-legacy or it's config.

Upgraded to Ascii yesterday and also got this in Xorg.0.log.
Tried everything mentioned in previous posts with no result, downgraded back to Jessie (for now )
Is there a way out of this mess?

Did you install xserver-xorg-legacy and set needs_root_rights=yes in /etc/X11/Xwrapper.config?

To amend the Tablet PC problem, I installed the updated xserver-xorg-core from Ceres and installed the wacom driver, and it tablet now works without the startup delay. So I guess I did something wrong with regular Debian when I tried this before. But yes, good news if you have the Wacom delay problem!
