Ubuntu :: Strange Black Bar On Desktop?
Sep 8, 2010
I noticed yesterday, after what must have been the most recent updates, that my display now has a dark striped bar running down the right hand side of the display. It runs between the indicator applet and the deleted items bin on my standard Gnome desktop. I know it's not my monitor since I can see both of those items but maximised applications will not fill this area, even though the cursor is visible there.I've tried changing a number of display options but to no avail.

I've been trying to use MySQL in Ubuntu but I've been having some connection issues and in trying to troubleshoot that, I observed this strange behavior with pings in Ubuntu Desktops inside our network.
- All Ubuntu Servers we have (10.10 and 8.04) behave as expected
- All Windows machines behave as expected
- All 5 Ubuntu Desktops we have, (10.10 and 9.10) exhibit the following unexpected behavior:
If they have a local ip addresses and are connected within the internal network, either to a switch or directly to a router, pings take much longer to be sent. It's not a higher lag, it's the time between each ping that increases. I have to wait for around 5 seconds for each ping, but the time in the ping reply is less than 100ms, also they're all in order so I assume it's the system delaying the sending of each ping.
If I plug a USB 3G modem directly then it works as expected again (~1 sec between each ping sent). Is this an intended feature, that depends on the network environment, or is this something I should look into more closely?

For some reason, the desktop for Fedora 12 has the following closing tag:
Code:
</body>
<
I have just installed Fedora 12, and I am using GNOME. Even the live disc had the tags. I had assumed that after installing the software to the hard disk I would be rid of the problem. Apparently I was wrong. Google does not seem to bring up a solution. Has anyone else encountered this?

I use Debian Lenny on desktop. On bootup I get this strange message
Code:
Question one: what is hub 2-0:1.0? A utility? A library? A module?
Queston two: what does "enumerate" mean in this context?
Question three: I can't figure out what "port" is meant: a networking port something on the motherboard one of several I/O port/connector/sockets on the back of the computer? (Hope you know what I mean--- you stick USB connectors into them to connect your computer to a USB device, such as a USB mouse.) the one and only networking port/connector/socket on the back of the computer.
Possibly relevant: I sometimes but not always have a USB cable connecting my printer to one of the USB ports/connectors on the back of the computer at boot time. But the message always refers to "port 1", never 2,3,4. due to lack of options for getting on the Net, I use an Actiontek router which demands to be given 192.168.0.1 which would otherwise be taken by my computer, which instead gets 192.168.0.2. (Grasping at straws...)

The computer and system in question is the laptop from my description and openSUSE 11.3 with a different kernel from this repository :[URL]..free to move this thread if it should reside in the beta/prerelease forums section. The IMHO relevant information about my hardware and system is shown below.
The kernel I'm using :
Code:
grzes@opensuse:~> Linux opensuse.local 2.6.37.2-1-desktop #1 SMP PREEMPT 2011-02-25 19:59:41 +0100 i686 i686 i386 GNU/Linux
The hardware and drivers I'm using :
Code:

The computer was working fine last night, when I woke up this morning (I leave it on) it was making strange noises through the speakers and I had a blank screen, restarted a few times had some page full of code and wouldn't move on from there, I went out came back started it up and it did everything normally except instead of a desktop I had a black screen, however strangely enough when I press the power button on the PC a shut down menu comes up, and the mouse works and I can select from the options. I am on an Nvidia ION tho. How do I boot into a safe mode as such? as at the moment I'm using a ubuntu live CD to read the forums!
On the GRUB menu, seclect "Ubuntu (recovery mode)" (not exact wording). You'll get scrolling boot messages until you get to a screen with a grey box and some options. Use the arrow keys to select "x failsafe graphics mode" or something of the like. Press enter and you'll probably get a message that your card can't be detected or something. Press okay and continue. Your screen will be messed up, but you'll be in. It probably isn't the same problem, as you don't have an ATI card and can see a shutdown menu, but good Luck!
How do you bring up the GRUB menu? My PC isnt dual booted so I never see any menus at all, I thought all I had to do was press F8 during boot up? No, F8 is Windows. Hold down shift when booting to see the menu. Downloaded & Installed the 10.6 driver and everything is working fine. Unminimizing apps works much faster with this driver . However, /usr/bin/aticonfig --initial results in
Code:
Found fglrx primary device section
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.fglrx-2
/usr/bin/aticonfig: Writing to '/etc/X11/xorg.conf' failed. Bad file descriptor.
Right now I've tried what "jxtreme" suggested on quote nr2 however when I go into recovery mode I get a load of code scrolling through the screen as its supposed to but I never get any box with options as he says, it just gets to a point where there's a small white cursor flashing at me half way down the screen and it stays there...

This morning I did some recommended updates for Lucid with update manager. This afternoon at start up I get a black screen after booting. I can hear the sound effect for the login, and if I key in my password, I hear the Ubuntu signature tune, i.e. it is booting and starting up. But my screen is just black with the arrow-shaped pointer, which I can move across the screen with the mouse. Other than that, nothin

I have an issue with my ATI 5800 card. Installation was flawless (dual boot with Windows 7 64 bit with all updates installed. Upon reboot, I have a black border around the entire Desktop. My screen resolution is set to maximum.Being new to all this, I am somewhat perplexed how the ATI Catalyst Control Center works.In Windows 7, this is the Scaling Option in the Catalyst Control Center which can easily rectify the situation. I have verified that the Catalyst Control Center is installed but I have no idea how to proceed to fix this.I have been searching Google for two days with no luck - lots of suggestions, but no fix. Can someone point me in the right direction as I would like to learn and understand how to use this OS.

The problem I am having is that when I try to take a screenshot the preview pane shows a black image and when I go to the location where the screenshot should have been saved.

i have an dedll inspiron 8600 laptop. i just installed the new ubuntu, 11.0.4 i think. i installed from a usb. in the installation i wiped the whole drive with no partitions. i booted it while connected to the Internet and it loaded updates as it went. as far i know, everything went just as it was supposed to. the new os seems to be behaving just as it should.
however, (always a catch, right?) now, the right third of my screen appears to have thin black Phoenician blinds from top to bottom.
i can still partially see the icons in the top right corner, but not well enough to use them really, but they are active. i tried rebooting, but it didn't help.
i promised my girlfriend that this would make our dog poo machine run great and we could get more work done faster. i really hope i didn't make a mistake. the dog house gets me claustrophobic.

I installed 11.3 32 bit KDE on my system I had been running 11.0 32 for over a year.nVidia card, AMD quad, 4 gig RAM.Blender runs fine, fast and clean, when I exit, it takes a couple of seconds before I get control back.If I play a game, ArmagetronIOQuake, FrozenBubble - when I exit I get my mouse pointer back in a few seconds, you see a couple of the windows open on the desktop for a brief second but all goes black. When you move the mouse pointer around the screen it changes as if it is going over an icon or window but it does not recover.

Trying to install Ubuntu 10.04 desktop (amd64) on this brand new system:
I connected the Dell ST2410 24" Full HD Widescreen LCD to the HDMI port on the ATI card and Windows 7 boots up just fine.
So then I put in the "ubuntu-10.04-desktop-amd64.iso" CD in drive and reboot the system. I see the Ubuntu logo with the dots for a while and then the LCD goes black. The LCD reports that there is no signal from the system. The power light in front of the LCD goes from white to amber. The keyboard stops responding.
I power off everything, remove the Ubuntu CD and reboot the system and it works fine again with Windows 7.
The CD has no problems. At boot time, I checked it for defects and it reports no errors. At boot time, I used this same CD to check the system for memory errors. No memory errors. I used the same CD to install Ubuntu on other systems and had no problems.
The 16X DVDRW Drive has no problems. In Windows 7 it can play CDs and DVDs.

I recently did a clean install to upgrade to 10.10 and I also got a 2nd monitor recently after upgrading. I want to be able to connect remotely to my desktop like I used to from my phone, but when I connect I get a black screen the size of my full desktop(both monitors) and I can move the mouse/type.

I have a problem after installing Debian and running it on my machine. Instead of taking me to a splash login screen, it instead remains a black screen like a console where I type in my username and password, and it remains in this black command line mode beginning ben@ben-desktop:~$. Like it does in a terminal. What can I do to resolve this? This is completely new to me and hasn't happened to me in Ubuntu or Mint. I am familiar with using the terminal for the odd task but obviously I can't use it like this without a visible desktop.

Cairo was working fine for me then randomly I see a huge black box behind it. I also cannot access my desktop effects along with it to activate compiz. I googled here and on the net trying different commands such as
:~> xgl-switch --enable-xgl
If 'xgl-switch' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf xgl-switch

I prefer ubuntu (which I have been meaning to install for a while) but my netbook currently has linpus lite on it. (It's an acer aspire one). One night I left the netbook sitting open (forgot to close it), and when I went to use it the next day, when I started it up, the desktop did not show the normal icons in the background. It still showed the bar at the bottom with the connection icon, power icon, etc. as well as the "Internet" search bar in the top right corner.
But instead of the usual linpus desktop icons, there are just black and white horizontal bars, with some coloured dots in the black bars. I can still use the terminal to open firefox, and presumably other programs. It still connects to wifi signals, and the bottom bar looks normal and functional. I am posting this message right now with my netbook, and it doesn't seem to have lost any functionality. I would much rather just click on things most of the time instead of opening terminal for everything.

openSUSE 11.2 i586, ASUS P3-P5G43 Rev. R1.04G Intel Core2 Duo CPU E8400@3.00GHz, Intel G45/G43 Chipset The Problem: The screen is for the WSXGA+ (1680x1050) standard. This resolution was detected, at the initial install and later with sax2. It shows the desktop with a 1 inch wide black area along the right border of the screen and that is exactly what is missing at the left border (i.e. invisible). It is like the desktop is shifted to the left of the screen. As far as it is visible the image is crisp and clean. Lowering the resolution to 1280x960 works ok, but the aspect ratio is no longer correct. I have checked the archives and found Intel integrated graphics - openSUSE Forums but trying different hints from the thread did not help.

I started an upgrade from Ubuntu 8.04 to 10.04 and it stopped with the message: Ubuntu desktop is listed to be removed but is on the removal blacklist. Then it restored back to 8.04. I don't know how to resolve this - it would be alright to remove the old Ubuntu desktop.

Few days after installing Ubunto 9.10, during installation of gstreamer, the installation utility got stuck, and with it the whole desktop icons. (I think the gstreamer has nothing to do with it). When I tried to execute some icon, like the terminal, it will not open. After restarting the computer, I get a tty1 login terminal and not the graphical one (tty7). When pressing Ctrl+Alt+F7, nothing happens. It switches to a black screen. "sudo startx", gives some error log. I already reinstalled the X-server, ubuntu desktop and other stuff.
What can be the problem? Is it related to my video card (nvidia 7600 GT)? I didn't install any nvidia specific driver. This happened to me earlier and I reinstalled Ubunto. I think maybe I should move to some other distribution.

I turned on my Acer laptop and during bootup it seemed normal. After it passed the blue Acer logo, all I could see is a black screen and a black cursor outlined in white in the shape of an X. Thinking it would be a one time thing, I turned it off again.it still was a black screen.
