When logging in, I suddenly got a message saying "It appears you do not have the hardware to run Unity", and it initialized the old GNOME 2 desktop.
Ofcourse I have the hardware to run Unity (an NVIDIA GTX 580), and it has worked normally until now...
Now Unity won't come back, even after logging out / in or rebooting. The video driver works normally and NVIDIA X Server Settings does not show that there's anything wrong with my video card or drivers.
Is this a bug? Did this happen to anyone else? How do I get the Unity desktop back?
I just upgraded to 11.04 today, and was playing around with the compiz-fusion settings. The first thing I checked was the fade to desktop box, and that froze up my computer. I let it sit for a little bit, but eventually got bored and just turned off my computer via the power button. When I started it up, both the tool bar on top and the launcher on the side had disappeared, and I don't have a clue how to get them back.
My unity toolbar has disappeared. The old style ubuntu panels have appeared in its place. This was happening on occasion before, but restarting the computer would get rid of it. This time unity has been gone for about a week, through many reboots, driver re-installations, etc.I just installed a new graphics card, which is working fine on the windows partition. Unity would fail to load on occasion with the old card, too. I know the new card works with Ubuntu, because Unity was working fine with it for about a week.
I'm running Ubuntu 11.04. The old card was a GeForce 7900 GT, the new one is a low-profile Sparkle GeForce 8400 GS.
I originally had the nvidia driver form the nvidia website installed instead of the = one from the repository. I uninstalled it and used apt-get to install nvidia-current. My video works fine but when ever I click the applications button all of my installed software is gone under all applications. I can still access my programs it's just under all applications nothing shows up, this is annoying. Is their any way to fix it or should I just switch back the driver?
I just upgraded to unity and everything is fine. Then I accidentally enabled Desktop Cube and Cube Rotation. Suddenly, the top part of windows that you normally use to drag the window or close it etc. started disappearing. In a panic, I rebooted. Upon reboot I found myself in an even bigger mess than I could have imagined. Not only did this fail to fix the problem previously mentioned, it also caused the sidebar and the ubuntu bar at the top to disappear. Desktop icons still show, and my cursor is fully functional, but other than that, my system is unusable.
after a lot of testing and tweaking done in natty 64 bit while running as live usb, i decided to install it clean on my laptop. everything is working fine (courtesy the time i spent to get things work in live usb) i installed gnome shell too and now have an option of unity / gnome shell and classic.
today being the 2nd day, i got the following problems.
a) the global menu that was being displayed in unity is not working. its funny to note that firefox global menu is working but not for nautilus or any other apps.
b) conky is displayed in unity and classic desktop but not in gnome-shell. i also followed this link to get it working in start up = > [URL]
still not working. when i issue the top command, i can see that conky is listed in the processes but not displayed..
I've just noticed this morning that the number shortcuts that normally appear when holding the super key to show the Unity launcher are not there. The s, a and f shortcuts remain however. Also, just pushing the numbers that should be there doesn't do anything.
I've just upgraded from Maverick to Natty and things were mostly working fine until this. I'm not sure what changes have happened between now and then and I don't remember any major changes in that period.
I just tried to take a screenshot and opened GIMP to save it and I checked again and they have reappeared. So, I guess the new question is why did this happen? How can I solve this problem if it happens in the future? Should I mark this as solved? I don't really understand what happened either way.
I was recently having problems with Me TV, and I had to kill it in a terminal window. When I killed it, it didn't release the DVB-T stick and when I launched Kaffeine, it told me that there was no device available. I re-booted rather than trying to figure out where the lock file was or whatever the problem might have been. Now, when I boot into my desktop, I am missing the menu bar and the task bar. Also, under Applications -> Settings -> XFCE Settings Manager, the Panel icon doesn't launch any settings dialog when clicked. How can I get my menu bar and task bar back?
For some reason, I can't get network-manager to appear on the task bar so that I can edit the connections. Also, network manager doesn't appear in system/prefs menu. if I try typing at the terminal 'sudo nm-applet" it says "An instance of nm-applet is already running. ** (nm-applet:9074): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager." If I inspect the system | preferences | startup apps , network manager is selected with the command "nm-applet --sm-disable".
I can see "network-manager" shown in /etc/inid.d but "sudo network-manager" gives "command not found". Anyone know what I have to do to get it working ? Uninstalling and re-installing hasn't worked. I have tried installing Wicd and that shows Lan & wireless connections ok but it *doesn't show my usb data-dongle* which I've just got working using the very useful application UsbModem_Switch by Draisberghof .
So the workaround for me is to call that connection manually ( if I need to use the usb data-card dongle ) with the command "sudo usb_modeswitch -W -c /etc/usb_modeswitch.d/0471:1210". However, if I can get the network-manager applet thing to show up and use that it would be easier. Or is there a better alternative to Wicd which can handle usb data-card modem connections ?
The network manager applet has disappeared from my top panel so now I cannot see what local wireless networks are available. I just came from the library and was unable to connect to their wi-fi because the computer wasn't trying to detect it. All I have is a network connections applet that seems fairly useless as it just gives me info on networks I've used in the past and not on any currently available networks.How do I get this Network Manager back and functioning?
Yesterday while trying (unsuccessfully) to get a new Bluetooth dongle set up I lost the network manager applet. When I rebooted, after giving up on Bluetooth in Ubuntu, I had no way of connecting to my wireless network. In command line (iwconfig & iwlist scan) I was able to see the wireless router. So the wireless card is working correctly. How do I reinstall the network manager applet? Oh even when use a wired connection to the router there is no connection.
Its disappeared before and its gone again> Last time this happened there was a root input which solved the problem but did not take a note of it and cannot find it through google this time Basically left my Linux Acer Aspire One and when I returned to it, connection manager had disappeared and cannot get it back.
All my panels and desktop and wallpaper disappeared. I don't know how to get them back without restarting KDE4. I have too many things open. I can't right click the desktop > appearance settings and I don't know what to input into alt+F2 to get that system settings menu. Any ideas?
Running Slackware64 13.1 here. I started up Firefox this morning and all the text is completely blank - all the menus have disappeared and everything. I can't really think of a great way to explain it clearly so I've attached screen grabs of Firefox and Thunderbird (which has the same problem). Other GTK apps seem to be fine, it's just the Mozillas as far as I can tell.
I have tried removing both with code...
And then I reinstalled both Firefox and Thunderbird from .txz files I downloaded from a repository, but they're still the same. Firefox version is 3.6.3 and Thunderbird is 3.0.4.
Since my video card cannot run Unity (3D), I jumped at the opportunity for Unity Qt but just recently when I logged in the top bar did not appear at all! How do I get it back? # gnome-panel pulls up the Gnome one but not the Unity one.
i feel really stupid for "upgrading" to gnome 3 to try it out and read warnings saying it can mess up your system. i went on thinking oh it'll be fine and the update process messed up or something. now i have a barely functional desktop and just want to go back to unity 11.04. i added the ppa from[URL]
I reverted back from Gnome3 to Unity using ppa-purge, but now I have 2 annoying issues: The launcher reverts back to its default after login/logout. Any extra items I "Keep in launcher" are gone. The clock is stuck in 12h mode and it doesn't take any new settings. 24h clock, showing seconds etc. all fail.
I have 2 different systems affected, one 64-bit and one 32-bit (pae kernel).
Running Ubuntu 11.04 and installed Gnome3 upgrade. Messed things up big time. Ubuntu will load, but will shut down when I try to access almost anything but terminal. How can I remove Gnome 3 or try to get back to Unity desktop or whatever.
After playing around with Ubuntu Tweaks to remove the "Recent Documents" logging, I somehow ended up losing the icons for "Applications" and "Files & Folders".
I tried lots of different things but the only thing that seemed to sort it was this:
Log out. Log in under Ubuntu Classic (for some reason dropping back to tty with Ctr, Alt and F2 didn't do it). Bring up the terminal and do code...
Log back into Ubuntu (not classic) and hopefully, you should end up with all icons back as they were.
This worked for me but I can't remember if I'd gotten rid of the ".recent-documents.xbel" file in my home folder first, so if all else fails you could try that before you start removing and re-installing Unity.
I have an Asus/Intel setup with integrated graphics that has been running Unity no problem for a while. I temporarily installed a separate NVidia card to do some hardware compatibility testing for another system that apparently couldn't hack it for Unity and forced it back to Classic. With the Nvidia card removed and going back to the integrated video setup I can't seem to get Unity running again. At the login I've toggled back and forth between Ubuntu (Unity) and Classic to no avail. Is there some way to reactivate it?
