Ubuntu :: All Panels Have Disappeared After Computer Froze
Nov 15, 2010
I'm currently running it as a dual-boot together with Windows 7. I hadn't had any problems up till yesterday, when all of a sudden Ubuntu stopped responding (I wasn't doing anything special, running firefox and mathematica) while opening a new tab (.....). I waited for a few minutes, still no response, and then hard booted it. When starting it up again, all my panels had disappeared.. The pictograms on my desktop are also moving up and down about a pixel continuously about once a second. I'm still able to run a terminal using shortcuts, and thus launch any program, but I have no idea how to recover the panels, and am still wondering how to prevent them from disappearing. I can make a screenshot on request, but there is really nothing to see except for a few pictograms. I am also using two monitors and 10.10 if that is of any importance.

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?

My computer froze and I had to do a hard reboot and now when I try to boot into Ubuntu the grub menu comes up and I choose my kernel but then I just get a blinking cursor. I can't even get into recovery mode!

After the last update this morning, which involved, among other things, the updated version of the linux kernel, upon rebooting, the computer froze at the fedora logo.

Whenever I log in, restart, etc... There are no panels shown, I have to alt+F2, open terminal and run killall gnome-panels in order to have panels shown again. Is there a way to fix this?

I find that I prefer have both panels located at the screen top. That way I don't have to go to the bottom of the screen for one thing, then back to the top for another. I arranged the panel so the regular top one is on top,then the panel that contains the open applications is underneath.The problem is, when I reboot, the panels lose their order. First, the regular top panel initializes, then the bottom ones starts and pushes the first panel down, which becomes what you see in the picture: I would like to find a way to keep them in the opposite order of what you see in the picture, but every time I reboot they end up in that order.

While upgrading to a newer version of Ubuntu I noticed a warning saying that the installation/upgrade should not be interupted. Unfortunately though, during this process my computer froze up and I had to shut it down. Ubuntu no longer starts on my computer. I still have Windows though, which is what I'm using now.

I am working on the newest version of Ubuntu Linux on VirtualBox under a 64-bit Windows 7 host. When I was working, VirtualBox froze, and I hadn't saved my work in Ubuntu. What should I do?
(This happened after I installed the extension pack for USB 2.0 and I went ahead and tried to access a USB port. I suspect that this led to my current situation.)

I started the upgrade last night, and around 12:03 it locked up the system and became unresponsive. I could move the mouse around the screen, but nothing was able to be interacted with, and the keyboard commands I could think of were not working. The upgrade manager said 10 minutes were left and it was in the process of updating the boinc-client (not a compiled version the one listed in the package manager). I left it until about 4:30 this morning and tried to reboot since I couldn't seem to accomplish anything else. The system came up stating it could mount root and just about everything else. So I burned a CD with 11.04 and booted off the CD and am now using the "Try Ubuntu" mode. I checked the file system and the folders I would expect to be there were.

Machine is a Dell Optiplex GX260, Pentium 4 with ATI Radeon RV200 QW [Radeon 7500]. I believe this is an AGP graphics card. I also believe that the graphics card is the root of my problem. In Karmic, I could get the computer to suspend. but it would not resume. The monitor would not initiate and it seemed as though the system froze. Only way out was a hard reboot. Hibernate worked for me without any problems, so it was no deal breaker. Now in Meerkat, Suspend behaves exactly as before. However, I can not get the system to go into hibernation.
The monitor goes down, but the system seems to freeze and never go down. I have tried editing the options in the acpi-support file to no avail. I have tried disabling compiz (which works amazingly well with this card), to no avail. I am using the open-source drivers and I have not tried the closed-source drivers in this system. I tried the closed-source drivers in Karmic and they made no difference. I may try un-installing the ATI card and fall back on the on-board Intel chipset to see if that solves the problem. Only then, I will loose 3d effects, etc.

I'm re-posting here since I've gotten no response in the Installation & Upgrades Forum.
While running the Update Manager my system froze and all that I knew to do was power down and power up again. I restarted the Update Manager and still have errors.
The original thread is at: [url]
This is not a crisis. I can re-boot and run without apparent errors. I thought about apt-get -f install but I don't understand enough. Is this a broken dependency problem? If this is a dependency problem will this (apt-get -f install) just clean-up the loose ends and then will the Update Manager pick up the pieces the next time I go through "check"? Is there possible harm doing this?
This system is at 9.10 and was up-to-date until I had this problem yesterday.

My recent setup was 32-bits Ubuntu 9.10 with / on a 20 gb partition and /home on a different partition on the same physical hard drive. Two days ago the system suddenly froze while idle. I rebooted and got the error message at start up that the system was unable to mount every unit that was listed in fstab. I troubleshooted by using a Live CD but could not find any reason to why i could not find the home partition. It lists in gparted but not in terminal using df.
I've made another install on a different physical hard drive and don't care about the previous installs, but I would like to get the data out of the home partition. If anybody have any idea what to try to access it

My system froze when watching a flash video and I had to do a hard reset. Now when I boot into ubuntu I can't open the software centre or the update manager. Is there a way to check what's wrong or a way to reinstall everything from terminal? Synpatic still opens and works.

I have been having some major issues with the update manager of ubuntu 9.10. I have had 3 instances so far where the updater froze either in the middle of updating or right after, and every time resulted in a corrupted file system. Two times it has happened to me which resulted in once having to completely reinstall and another was luckily saved by using Gparted on the live CD. But now my friend who i installed Ubuntu for has had the same problem. When it happened to me, I was forced to hold the power button to get the computer to turn off as it completely locked up the system. My friend however, was able to use the shutdown menu.

Yesterday my wife was using our laptop and an upgrade manager dialogue box came up. She clicked yes to install upgrades, but at some point during this process the machine froze. She restarted, and I haven't been able to successfully boot since then. the final screen when trying to boot from the hard drive reads:
Killed
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have /sbin/init.
No init found. Try passing init=bootarg.
[Code]...
I'm slowly getting the hang of Ubuntu. By now I know enough that a Live CD can fix most problems. So that's where I went after doing several searches about the error messages that were appearing. The menu screen works, but I can't get it to boot into the "Try ubuntu" mode. I tried changing the boot parameters to no avail. As the boot tries to load I can see a line by line report of errors- some are I/O errors and are in white, but many were in red, which seems bad from my mostly ignorant perspective. I saw lots of SQUASHFS errors among other things. I took a snapshot of the screen that was displayed when the boot failed- it's attached to this post (lots and lots of text to be typed otherwise). The reason I know it failed is because I've tried a half dozen times with the same exact result- once I let it sit for an hour+ just to make sure it was really frozen (a bit optimistic).
Relevant info: Ubuntu is running on a Dell Inspiron 8600 laptop. I think it's version 9, but could be 10. The Live CD I'm using is version 10 burned 1/4/2011. I'd be thrilled to hear any suggestions that folks might have.

I have a netbook, on which I installed the netbook remix. It had ran fine until one day, I shut it down while it was updating. Now, on bootup, it will take me to the login screen and then basically freezes. The keyboard and mouse do not work and I cannot login to any profile. I tried a clean reinstall, but it only finds the preferences I have and sends me right back to the login screen.

I currently do not have Wine. I have uninstalled it and plan to reinstall. The last time I had it on Fedora was like 2 days ago. I had a problem that was really irking me. I was playing Myth War 2 (which worked flawlessly on Ubuntu 10.10) and right after I started, I went to move my character in the game and I just froze. Wine would not do anything, so I force quit, restart and the same thing keeps happening over and over. I do not know what is going on. I have been told it is my graphics driver, but it is current and up to date.

Kubuntu 10.10 froze on me randomly. I shrugged it and rebooted. Then less than an hour later, another freeze. This was rare, so I started up Memtest86+ and let it go.
The results... were not encouraging.
Stock voltage on both. Never overclocked.
After pass 0 complete, swapped around various tests and ranges to check.
At pass 38, switched from full-range to test #5 2048M-3327M.
After pass 80, switched to various tests. No tests other than #5 generated errors.
So now my question is multipart...
One, is there anything that can be adjusted within linux itself to avoid triggering these errors (need to keep using this RAM for at least another week before I can afford to RMA it)?
Two, I'm assuming this does indeed point to RAM malfunction/damage, but if I'm wrong, what is going on here?
Three, if there is a way to adjust for these errors, should I still be RMAing it? If I do, I'm going to attempt to get some the same size/speed of ECC RAM. When I ordered originally, I wasn't aware the motherboard I'd picked supported ECC. Now I am.
Seems I'm not able to RMA this RAM at present, working with the company I got it from, but that option's just about out. Now, I read something about a kernel module called badram, but I'm finding little detail on how to go about activating it properly. Seems like if I can disable the one chip these errors are all occurring via, that would solve the issue just fine.

Some of your private key files are encrypted for security reasons. In order to read them you have to provide us with the pass phrases. Server your.server.com:55 (RSA)
Enter pass phrase:
Server www.blahblahblah.com:55(RSA)
Enter pass phrase:
How to login ?
The cursor is blinking but I am unable to enter the pass phrase; the only thing I can do is press the power button to shutdown. Even if I leave the PC running for a hour I can't type anything.
I know how to resolve the problem if I am able to login.

I was logged in, but had not used the computer for about 48 hours. When I 'woke' the system, I could see that Thunderbird and Firefox were active, just as I had left them. I moved the mouse, the screen went black and the mouse pointer was visible (and could move). The system stayed like this for about 2 minutes, then wend down completely. I cut power, booted and got the login screen. Each time I put in my password, it looks as if it is loading but then just goes right back to the login screen. I have no problem logging in as root.

Any time i try to open skype it closes out fully in 5 seconds (not even in the processes anymore). I don't know why or how OR how to make it stop being so mean to me! i'm running ubuntu 10.4 32bit . I tried to boot it in safe mode and umm.. it froze? or crashed? well it was on the black screen with the blinking dot for like 20 mins before i gave up on it (Hiting enter or esc or anything didn't work). There was a key symbol on my panel before skype acted up(It closed and disabled something.. i've never seen it before). Adobe also crashed, and linux did a small update (nothing with skype).

Yesterday, I was doing some work (Don't worry, I didn't lose anything), and I restored a terminal I had open, and it completely froze! I couldn't do anything on the desktop, so I tried rebooting. Doing that resulted in an error when booting. It would say "bin/sh : Can't mount" or something like that (Can't quite remember) not too long after trying to start up, and it would leave me stuck with some weird terminal. The only command I know on this new terminal is reboot. What should I do?
Note that I just installed Debian two nights ago and it was working perfectly fine until last night...
The error says "/bin/sh: Can't access tty; job control turned off"
