Low graphics mode in multi monitor setup after upgrade to 16.10

[isotope]

Hi,
After upgrading from 16.04 to 16.10 my multi monitor setup is unable to reach login screen. Computer is Panasonic CF-52 on dock station with two external monitors. The error says low graphics mode enabled.Used to work just fine in previous distributions. the last error in the log file says: ScreenInit failed for driver 0. I have Intel graphics.

Workaround found so far: boot laptop out of dock station, then dock it and monitors are recognized no problem.

Troubleshooting done:
Reintsall Ubuntu from thumb drive - reinstall option: same results
Reinstall Ubuntu from thumb drive - clean install except for /home drive kept: same results
Run X -configure: same results

Regards,
isotope

Maybe as my reported bug? (Bug #1634152)

Can you confirm my bug if it's a similar problem, pls? Thanks!

Hi,
I have done some further investigation and these are my results:

- Clean install of Ubuntu 16.10: No luck
- Clean install of Ubuntu Gnome:
   - GNOME and GNOME Classic (I believe) sessions - same result, although it managed to reach login screen. But once I type in the password and hit enter, both screens flicker and I am bumped back to login screen as if I never logged in. No error messages, nothing.
   - GNOME sessions with only one external monitor connected to the dock station. In either case all was good and I was able to log in etc.
   - GNOME on Wayland: DID ACTUALLY WORK! So, I moved my system to that GNOME session for the time being. Good for a change too :)

Regards,
isotope.

Hi! At last I... SOLVED!!!

Before I saw:

http://askubuntu.com/questions/436374/how-to-get-rid-of-the-gallium-0-4-on-llvmpipe-llvm-0x300-driver-intel-needed

...then I saw:

https://wiki.ubuntu.com/Kernel/LTSEnablementStack

...later, on a terminal, I've run:

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial

...and, after a restart, my PC returned to work with the correct "Intel® Sandybridge Desktop" instead of "Gallium 0.4 on llvmpipe..."!

I hope that it can help you.

Hi Paolo.

Glad to hear you managed to resolve the issue! Did not work for me though. Also there seems to be some progress done. I tried fresh install with downloading latest updates and this time it went as far as splash screen on both external monitors, but then all the same. Flickering and eventually bumping to low graphics mode.

Regards,
Vadim.

I was able to permanently (I hope) fix the problem.
After reading around, examining system files, logs and a lot of guesswork, I noticed that /usr/share/X11/xorg.conf.d had amdgpu configuration along a bunch of others but no intel. So I tried to find a sample file on the web and created (as root) 20-intel.conf containing:

Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
EndSection

rebooted, and a miracle happened! It loaded with both external monitors working again! Lost the configuration though, but after redoing monitor arrangement etc and rebooting again it was all good. I hope this helps someone.

Regards,
isotope.
