I am facing a very frustrating issue with my computer right now. I successfully upgraded to Ubuntu 12.10 this afternoon, but after the upgrade, the graphical user interface seems completely broken. To be more specific, I can not get the Unity bar to appear on the right.

I have tried many things, including (but not limited to) purging and then reinstalling the fglrx drivers, apt-get install --reinstall ubuntu-desktop, apt-get install --reinstall unity, tried to remove the Xorg and Compiz configurations, checked to see if the Ubuntu Unity wall was enabled (it was) in ccsm, all to no avail.

Could someone help me troubleshoot and essentially fix this issue?

NOTE: This is the output when I try to enable unity via a terminal:

it sounds like this issue askubuntu.com/questions/202574/… if you have a nvidia card –  blade19899 Oct 22 '12 at 18:03
    
Nope I have an AMD 6870, and I have installed the fglrx driver –  NlightNFotis Oct 22 '12 at 18:03

I have thus far refused to upgrade to 12.10 but stuck with LTS. I had installed 12.10 on one machine and had to reinstall LTS on it because I had no time to deal with all the ideosyncracies of 12.10 or whatever Mark Shuttleworth decided to declare war on our common sense. –  Blessed Geek Feb 24 '13 at 21:20

As i see in log compiz plugin init failed i would try to reset compiz manager to default settings maybe it'll help

Or else i recommend to completely* (with all settings*)remove unity via synaptic and reinstall it again or use terminal:

sudo apt-get install --reinstall unity,

sudo apt-get install --reinstall ubuntu-desktop

Think for yourself if is it usefull

Thanks for the answer, but it provides the same errors as before. –  NlightNFotis Oct 22 '12 at 18:09
    
maybe the issue is in these words in log :Unity is not supported by your hardware..Try to enable low graphic mode and see if it works. About this tweak here ubuntuvibes.com/2012/10/… otherwise for now i would recommend to install different desktop like gnome 3 or fallback. –  polarkatenuchie Oct 22 '12 at 18:16

I am only accepting this answer because it inspired me to install xfce via sudo apt-get install xubuntu-desktop which seemed to serve well as a work around until some time passes and I try unity again. –  NlightNFotis Oct 22 '12 at 18:48
    
i tried my best .. i posted own question and no one replied so i decided to help someone.These things i would do by myself in unity glitches.Sorry its not pro level. –  polarkatenuchie Oct 22 '12 at 19:02

I had the same issue and it appeared that it was linked to my AMD graphic card's driver.

I fixed it following this procedure. I used the 3rd-party repository created by Tomasz Makarewicz.

Basically, this procedure explains three ways to install the AMD Catalyst missing drivers. As it is well explain on the page, there is no point to copy the information here.

Hope it helps!

can you please tell me what system info says in system properties-graphic info after you installed makson96 package?For me it was vesa m98 so i dont know is it bad or not –  polarkatenuchie Oct 22 '12 at 21:24
    
Thanks for this answer, it fixed my problem. Also, I tried the script from the ati site and it did not work. I really had to go with the 3rd party repository option like you did. –  Moox Oct 30 '12 at 16:17

I had some hassle with the proprietary NVidia drivers too, but at some point was sure it was finally corrected, but Unity was still broken.

I also noted that using a guest account, Unity was displaying fine, so it was a per-user setting. This here helped: dconf reset -f /org/compiz/ (had to reconfigure the docking bar but that's acceptable).

Worked perfectly. Thanks. –  codeinthehole Feb 3 at 17:20

I had a very similar problem. I used unity-reset tool that I found from another post here:

From Git To install

git clone https://github.com/phanimahesh/unity-revamp.git
cd unity-revamp
chmod +x unity-reset.py
ln -s ./unity-reset.py /usr/bin/unity-reset

To run

unity-reset

From Amith's PPA To install:

sudo add-apt-repository ppa:amith/ubuntutools
sudo apt-get update
sudo apt-get install unity-reset

To use:

unity-reset

I did install it earlier on, from amith's ppa, but it didn't seem to help me. –  NlightNFotis Oct 22 '12 at 18:47
    
Doesn't work. This is a problem with the drivers rather than unity itself. –  Timmmm Mar 11 '13 at 21:45
    
Wow! Brilliant tool! –  Rafał Cieślak Mar 20 '13 at 12:26

For cards newer than the 3XXX the best way to resolve this is to install the kernel headers. First you need to revert to the original Xorg driver that does work. (right mouse click on the desktop and selecting "Change Desktop" get's you in the menu where you find "Software Sources")

It appears that the proprietary drivers need to be compiled to the kernel but can't due to missing headers.

sudo apt-get install linux-headers-generic 

After that just install the proprietary driver you fancy. It worked for me.

sudo add-apt-repository ppa:makson96/fglrx
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fglrx-legacy

finally reboot your PC

This worked for me on ATI4200 (I've tried everything else but this worked...)

However, if something doesn't work out, you can always remove the repository and go back:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:makson96/fglrx

source

Thank you very much! The fglrx available at repos screws up compositing (and not at all reducing power consumption as compared to the generic graphic driver). This worked :) –  piyush Feb 16 at 0:25

Are you using the fglrx drivers (for ati cards)? In that case this is a known bug. Please go to https://bugs.launchpad.net/fglrx/+bug/1068661 and report that it affects you too (the option is near the top of the page).

You can remove the fglrx drivers and revert to the open source drivers (which should work) by following the instructions on http://wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide#Removing_Catalyst.2Ffglrx

If you have an old ati graphics card see Showpaths answer
