Ubuntu-desktop not working when suspend/resume or connecting an external monitor -after upgrade this week (14.04)

[Milton]

I was happily using 14.04 with my Lenovo Y50. When I installed it, I had some troubles making my NVIDIA GeForce GTX 860M 2GB works with hardware acceleration, etc, but at the end everything was OK.

THIS WEEK (around 02/25/2015) an update destroyed this beautiful equilibrium: I can't resume after suspend and I can't plug or unplug my external monitor without having a weird problem:

a) Desktop "moves" half of it size to the right.

b) Mouse works, but I can't click on anything. The only workaround is killing the Xorg, and loosing the session.

What I tried, without success:

1) Downgrade Compiz (the first suspect, it was upgraded this week). Nothing.

2) Install ALL possible NVIDIA drivers:

2.a) Nouveau

2.b) Nvidia 304 & Nvidia 304 updates (blacklisting and purging nouveau)

2.c) Nvidia 331 & Nvidia 331 updates (both from repository and NVidea website). (blacklisting and purging nouveau)

2.d) Nvidia 340 (from Xorg-edgers ppa). (blacklisting and purging nouveau)

2.e) In every case, I purged previous drivers before, reconfigure Xorg, etc, etc,etc.

3) Reinstalling Unity and Ubuntu-desktop

I honestly don't know what else to do, but this situation it's very annoying.

Any ideas? Please?

THANK YOU

A follow up: someone suggested to install the NVidia 346. Same result, the problem is still there.

[Milton (miltonlaufer)]

Someone has an answer? I'm starting to consider going back to Windows... My laptop is like a brick if I can't suspend it :(

[Milton (miltonlaufer)]

I found a workaround.

I created two scripts (one of them I found it on this website, but now I lost the link).

Let's called the first script: "discover_session_bus_address.sh"

#!/bin/bash

# Remember to run this script using the command "source ./filename.sh"

# Search these processes for the session variable
# (they are run as the current user and have the DBUS session variable set)
compatiblePrograms=( nautilus kdeinit kded4 pulseaudio trackerd )

# Attempt to get a program pid
for index in ${compatiblePrograms[@]}; do
   PID=$(pidof -s ${index})
    if [[ "${PID}" != "" ]]; then
        break
    fi
done
if [[ "${PID}" == "" ]]; then
    echo "Could not detect active login session"
    return 1
fi

QUERY_ENVIRON="$(tr '\0' '\n' < /proc/${PID}/environ | grep "DBUS_SESSION_BUS_ADDRESS" | cut -d "=" -f 2-)"
if [[ "${QUERY_ENVIRON}" != "" ]]; then
    export DBUS_SESSION_BUS_ADDRESS="${QUERY_ENVIRON}"
    echo "Connected to session:"
    echo "DBUS_SESSION_BUS_ADDRESS=${DBUS_SESSION_BUS_ADDRESS}"
else
    echo "Could not find dbus session ID in user environment."
    return 1
fi

return 0
Save it an then, in the same folder, create another script called "recover_unity.sh".

Code:

#!/bin/bash

export DISPLAY=:0
source ./discover_session_bus_address.sh unity
unity &
save it and give both script execution permissions: chmod +x discover_session_bus_address.sh chmod +x recover_unity.sh

Now, every time unity freezes, use CTRL+ALT+F1, login and, within the folder where those scripts were saved, type

source recover_unity.sh

On thing is worth mentioning: if I disable all the Compiz effects, plugging or unplugging an external monitor does not turn the desktop and windows unresponsive, but unity panel and launcher, and also window decoration (with the close and minimize buttons) disappear. Does this give any clue? (particularly taking into account that Compiz was upgraded last week, when the problem started).

I posted the same problem on askubuntu and there are more people with this problem:

Please add your dpkg log file /var/log/apt/history.log so we can have a look at what packages were updated.

[Milton (miltonlaufer)]

Thank you. Here's attached my history.log

[Milton (miltonlaufer)]

Sorry, that history log does not contain the information about the updates that caused the problem (it started around 2/25)

Here's the previous one.

I'd guess it is something to do with this upgrade:

Almost all of the packages updated come from a PPA, not the official Ubuntu archive, and you should try the official versions of the Ubuntu package to see if it is a bug with package in the Ubuntu archive. If it is not then you should take up this issue with the maintainers of the PPA from which you are installing packages.

[Milton (miltonlaufer)]

Thank you Brian.
I removed all the suspicious PPAs using ppa-purge (sudo apt-get install ppa-purge)

sudo add-apt-repository ppa:xorg-edgers/ppa (just in case you had disabled the ppa before(
sudo apt-ges

(Sorry, the message was sent unintentionally)

Thank you Brian.
I removed all the suspicious PPAs using ppa-purge (sudo apt-get install ppa-purge)

sudo add-apt-repository ppa:xorg-edgers/ppa (just in case you had disabled the ppa before(
sudo apt-get update (idem)
sudo ppa-purge ppa:xorg-edgers/ppa
sudo add-apt-repository --remove ppa:xorg-edgers/ppa (I don't remember if this is necessary or if ppa-purge already does this)

 the same with ppa ppa:bumblebee/stable

then
sudo apt-get purge xserver-xorg*
sudo apt-get purge nvidia*

then
sudo apt-get install nvidia-331
sudo reboot

after reboot, not only everything works perfectly (plugin or unplugging the external monitor, suspending, etc) but the hardware graphic acceleration is faster than ever! (running glxspheres )

THANK YOU!!

Okay great! I'm setting the bug status to Invalid then.
