Public bug reported:
SUMMARY
- laptop with NVidia card and Optimus technology
- xorg configured ages ago to automatically switch between built-in and
external monitor when plugging/unplugging
- "clean" Ubuntu 15.04 after upgrading from 14.10 from 14.04
- no nvidia-* nor bumblebee-* was installed (that's what I mean by "clean")
- everything was working perfectly fine while only using integrated intel GPU
- I installed NVidia-340 and nvidia-prime (and whatever) via Software & Updates
-> Additional Driver
Result:
* Boot with external monitor connected => keeps crashing forever at the login
screen
* Boot without external monitor connected => seems to work with built-in screen
(at least for the few minutes I tested)
* Connect external monitor after boot at login screen => xorg crashes once or
twice, then both screens go black
* Connect external monitor after logging in => both screens go black
* Disconnect external monitor => built-in screen remains black, never turns on
again, unless Xorg crashes
Basically, the laptop is completely unusable. NVidia-prime and nvidia-340 screw
everything up beyond imagination.
I was lucky tojust be able to recover from that, uninstall all nvidia-stuff,
and get my working system back.
MORE DETAIL
Until recently I had Ubuntu 14.04.
I had nvidia-331 installed but unused since ages ago. I had disabled them (if I
remember correctly) by going to
Software & Updates -> Additional drivers
(the same I had used to install them)
and choosing to use Nouveau instead (back), because I had experiencing a lot of
glitches with NVidia-331.
This was even before I upgraded to 14.04.
Because my laptop has Optimus technology, I was only using the
integrated Intel GPU.
At some point I had also installed bumblebee, but I had never figured
out how to actually make any use of it.
I had Xorg configured so that, when plugging an external monitor, only
the external monitor would be used and the built-in one would turn off;
and when unplugging the external monitor, the built-in monitor would
automatically turn on. So I only use one monitor at a time. I guess I
configured this via the System Settings -> Displays
All this was working fine.
When the fix for #1431753 was released, nvidia-340 got installed and,
against my will and without notice, they were somehow enabled, so I
started experiencing #1220426 and #1483388 (but nothing comparable to
what I'm describing in this report).
So, I apt-get removed nvidia-* and bumblebee.
After that (and across several reboots) all was working perfectly fine
again. Again, I was only using the shitty integrated Intel GPU (without
even the hardware acceleration that it supports, btw, but that's another
story), but I had no issues.
Then today I upgraded to 14.10 and immediately after, to 15.04.
Everything kept working smoothly, including automatic screen switching
when plugging/unplugging the external monitor.
Then I thoughy I'd give NVidia-340 another try. I thought maybe a fresh install
on 15.04 would work.
I went to Software & updates -> Additional Drivers and I selected "use
NVidia-340"
That installed nvidia-340, nvidia-settings, nvidia-prime, and something-
nvidia-else.
I rebooted.
At the first reboot, I had the external screen already connected.
After the boot completed, xorg started to crash again and again like crazy. The
login screen would appear and disappear from both screen at a few seconds
intervals, and I would hear the drum sound every time (and could not finish
typing my password and logging in).
THE SYSTEM WAS UNUSABLE, I COULD NOT LOG IN.
So I rebooted without the external monitor connected.
I then connected the external monitor while still at the login screen. Xorg
crashed one or a couple of times, then the built-in screen turned off but the
external one didn't turn on either.
So I disconnected the screen; after a while Xorg crashed again and only then
the built-in screen turned on again
I rebooted again, and fully logged in without the external screen connected.
Then I plugged in the screen
=> again, the built-in screen turned off but the external one didn't turn on.
I disconnected the screen, and the built-in screen never turned on again.
So, I rebooted without the external monitor, uninstalled all the nvidia-related
stuff, rebooted, and now again everything is working (without using the NVidia
card, of course).
