desktop/unity buggy in 16.04 after upgrade/restart

[realityrsv]

Hi everyone, semi newb here..

Been running ubuntu 16.04 for a few months and just starting to get my head round few things. Today was a major brain bender trying (and eventually succeeding) in getting my epson printer to work using CUPS... but i digress...

After this minor success i did a restart (all fine) then updated the system as i noticed an upgrade waiting in the software centre. Restarted again and now i have issues, which are:

• If i move the mouse over the launcher bar, it dissapears. about 5-10 seconds later, all the desktop icons disappear too, leaving a nice uncluttered view of my desktop background. Another 10 seconds or so later, everything reappears again. If i haven't moved the mouse during this time, i can now click and open a program, otherwise the cycle continues.
• I cant shutdown or reboot from the top menu, the option drop down but if i click on something, the above problem occurs.
• If i do have open windows, they do not always have the x,minimise,maximise buttons or submenus.

I have searched for solutions and tried various things:

• I have reset compiz config (tweaked a value in here a week or so ago to try speed up a very slow system)
• tried pretty much everything in here https://askubuntu.com/questions/1738...o-dash-appears
• tried updating, reinstalling unity and ubuntu desktop.

I'm not yet aware how i can generate a report that you might find usefull in helping me, but can follow clear instructions. terminal works fine and i now know how to restart though that etc.

Can anyone help? Cheers and sorry for long post

[realityrsv]

oh dear... just tried something i had missed from the link i posted above (mv ~/.config/dconf/user ~/.config/dconf/user.old)
this has reset the launcher completely (it is back on the left of screen and missing some apps i had added to it) and my background pic has been replaced with the default. but the problem persist.

I logged in to a guest session to see if that had the same issues (it did) and provoked a crash report. It was too long to write it all down and i couldn't copy. the jist of it was:

executable path
/usr/bin/compiz

compiz crashed with SIGSEGV

Please install..

sudo apt-get install inxi

then enter into terminal.

inxi -Fxz

and report the results here please.

Thank you.

Please install..

sudo apt-get install inxi

then enter into terminal.

inxi -Fxz

and report the results here please.

Thank you.

I'm experiencing the same issue as the OP. Incidentally, the very top icon (not sure what it is called but it opens a search box for applications) does NOT work by waiting as the other applications do. FWIW.

Here is the output from inxi -Fxz on my computer:

I am so glad people are on this. This has also been reported in askubuntu

https://askubuntu.com/questions/9925...gfaults/992870

and if you look at this

https://bugs.launchpad.net/ubuntu/+s...y/+bug/1741447

and go down to axoin's response, s/he claims that downgrading mesa actually solved the problem.

I hope this is fixed quickly. I have been using LTS releases for 10 years and this is the worst regression I have seen yet.

[iraj1101]

I am having exactly the same problem. This is definitely the worst 'regression' I have experienced with Ubuntu as well. Also running 16.04 LTS. ALT + TAB also does not behave properly.

Good Day,
Relative Noob to Ubuntu 1604 (loaded on pc in August-September 2017). I am seeing the same issue since January 4-5th, 2018??? There was an update that occurred on the 4th or 5th and I started seeing the disappearing launcher and window frames as described in the original post above.
Sorry, I don't know just what or how to provide some details on my system to help in troubleshooting this. I tried following some remedies in askubuntu after finding a bunch of "half installed/configured" lines in the dpkg.log. No success with those efforts but no further damage either. I did much of what realityrsv wrote in his original post to resolve.
I have about reached the limit of my skill set on this and am hoping a resolution is found that can be dumbed down for my understanding. I did review the entry above (entry by interglossa, in second link, by axoin) that referred to manually downloading mesa/17.0.7-0ubuntu0-16.04.2 and build/13231714. But I am not figuring out the download and install steps(s) (sudo dpkg -i *.deb keep getting errors of file not found?) as outlined in that entry.
I did check my video card performance in Windows 10 (dual boot on this same pc) and noted no issues there.
Thanks for your time. I do appreciate it!

Good Day once again...
I followed this link, https://bugs.launchpad.net/ubuntu/+s...y/+bug/1741447, found in interglossa's entry above and followed the suggestions by axoin.
I stumbled upon the fixes to my errors in downloading and installing those files and rebooted.
I had to make some further changes with Package Manager but things are much improved. EDIT...I had to perform the install and Package Manager routines with the other user on this Ubuntu box to have everything back on track. As it looks like now.
Thank you for the info!
I look forward to the day when I can help a fellow noob. I will endeavor to NOT be a pest until such time.
Take care.
