Hardware :: USB Port Results In Instant Death
Jan 16, 2011
Simple but puzzling problem. When I plug my USB mouse into one particular port, the mouse does not activate. Unplugging it kills the laptop. My laptop will not turn on unless the battery is removed and reinserted. I think this may be a power supply issue, but I'm not sure. I just recently purchased a new A/C power cable because my old one was toast, but this problem has been happening since before then. I'm getting a little irritated and was wondering if there is a diagnosis and solution to this problem.

Lately, my laptop has been encountering instant death. Completely powers off, the end, good night. This happens a couple times a day. After these deaths, the laptop will not turn on unless the battery is removed, the A/C power cord is unplugged, and then both components are put back in. Judging from this, I think I need a new battery and possibly a new power cable. Buying new ones for my laptop, though, comes out to about $100, and I'm informed that my particular laptop model has been known to have some issues. (It's an ASUS x83v)

I just ran the port scanner from the Network Tools utility a few times within a few minutes (see screenshots). How can there be different ports open each time? I know that port 631 is for CUPS, but what about the other ones? Could someone help me understand what is going on, or at least point me in the direction of some good information?

I was testing the security of my Ubuntu 10.04 64bit install by running a port scan from [URL] and I came upon some odd results. It appears that basically all my ports are closed, but only Port 646 is dropping packets silently. Furthermore, Port 80 is open.

I'm timing how long it takes to run a command foo. I'm looking to append the results from the time command to a file, and discard the results from the foo command. I tried the following, but it didn't do what I want:
$ time ./foo > /dev/null >> output_from_time_command.txt

I want to do a simple port redirect, i.e. whatever comes trough whatever interface on port AAAA will get redirected to port BBBBI thought that iptables -t nat -I PREROUTING --source 0/0 --destination 0/0 -p tcp --dport AAAA -j REDIRECT --to-ports BBBBhowever it doesn't work, e.g. nc -v -w2 -z localhost AAAA gives:
nc: connect to localhost port AAAA (tcp) failed: Connection refused
while
nc -v -w2 -z localhost BBBB

I tried to install the 2.6.31.12 kernel (as suggested for security reasons) twice, and each time, I got a *BIG* mess up of the installation. Here is the story (I'll try to keep it short): The installation of the kernel was not a problem, it went fine both time (I just had to reorganize Grub entries a bit). At first, all was running normal. Suddenly, after having left the computer idle for a moment, I was faced with a black screen (blanker probably) and I could not wake up the system: no mouse, no keyboard, all seemed to be frozen and I had to press the reset button.
After the reboot, and as soon as the desktop was loaded, I got an error message saying that /var has 0 bytes left ! The nightmare began... The first time that happened, I tried to find what was wrong in /var and /var/log , but found nothing abnormal. The info given by the Diskinfo tool were strange, sometimes showing /var as 100% full, sometimes it was /home that was 100% full and some other times it was /. I tried to fall back to kernel 2.6.31.8 using Yast, but it failed at the middle of the process. At this point I realized that the system was very unstable.
I then booted the Install HD and run the repair mode. Some errors were found and corrected, but in the end, the system was not repaired; and worst, Grub lost all entries except the floppy one. (Hopefully, I knew how to boot the Install HD from Grub's command line). I tweaked again and again, and finally got my system up again with kernel 2.6.31.8 (don't remind all the steps). Recently, as the kernel update was still suggested, as there were other updates in the meantime (like mkinitrd), and as haven read anyone else complaining about 2.6.31.12, I decided to give a try again.
And again, a couple of days later, same symptoms: black frozen screen, no space left in /var. As I knew the system was unstable, I immediately booted the Install HD. Tried the repair mode and it failed (just mess Grub again). Tried to (update) install kernel 2.6.31.8 from there and it also failed. I then started the rescue mode and tried to delete some big files in /var (again I did not found any monstrous thing in there), then tried again the repair and update process with no better results.
From rescue mode, I finally deleted everything in /var (that was not a good idea as I also deleted some NEEDED files)... Got the system to boot, but only to the text login: nscd failed because of missing files in /var, starx failed because no X server found, ... Fed up, I lastly decided to "update" all system base RPM, the Gnome and KDE desktop environment from the 11.2 install HD, then update everything again with Yast Online Update.

I created a USB stick with Ubuntu 9.10, used it to boot a dell Inspiron 1550 laptop which has WinXP. I tested 9.10, everything went fine out of the box so to speak. But when I went back and tried to boot XP again I got a blue screen. XP starts in safe mode and no apparent problems are detectable but it will not start in Win normal mode anymore.

I've installed almost every version of ubuntu so far and four different versions on this computer, and I've never had a problem with the installation cd. The install cd on this new version however gives me only a purple screen of death with a white line down the middle. What is going on? The ubuntu-10.04-desktop-i386.iso file's md5sum is fine. I've burned it successfully on two different discs and still I can't install it. I've got a Dell 6400 with an nvidia geForce 7300 video card.

I've had it with 11.04. 2 days, countless posts read, and I still get the black screen of death. I want to go back to 10.10. Can I do it without a complete re-install, and if so, how?

I'm having a really odd problem since I upgraded to 10.04 on my IBM T40 laptop. Every now and then, especially if I'm using Firefox (so it seems), I will be in the middle of something and suddenly I get a black terminal screen that flashes a few lines ending in "checking battery state" and I get bounced back to the login screen. I log back in and all my work is gone (Firefox and whatever else was open has closed). I was on the web for a while tonight and in a few hours it did it three times. I never had this happen before in 9.10.
Any idea what's going on? If it matters I'm on AC power when this is happening. I haven't used it long enough on battery to know if it does it then or not.

I saw this post [URK] and I'm having the same problem up to the point of installing/updating aptitude. Here is the background: I logged in and just recently added another monitor and used Multiple Monitors from the software downloader to manage them. Last night they worked great and I was using the extended desktop. When I logged in this morning they were cloned and I couldn't get the buttons "clone or extend" to not be grayed out. I couldn't have cared less since I was just logging on to check email and things so I looked around for a second in the settings and was sidetracked by the display/window options. I was scrolling through the different themes and colors and then all of a sudden BAM! back to the login screen. I was using the arrow down key to scroll and like I said, immediate toss to the login screen. I made O.o? that face and tried to login and then I kept getting kicked back the same as the post I linked above. So...
I press ctrl+alt+f2 and log in. I see Welcome to Ubuntu! back to the aptitude step, when I run sudo aptitude update && sudo aptitude reinstall gdm I return sudo: aptitude: command not found. So when I do: sudo apt-get install aptitude I return E: unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

(ranting stopped, for now) I have ATI Mobility Radeon HD 4330 GPU in my Dell Zino system and finished the upgrade from 9.10 to 10.04 LTS and got the purple screen of death. tried the intel recommended fixes but got nothing. I cant even get into recovery mode.

I run a live cd I downloaded, right? Everything goes fine - it installs with no real issues whatsoever, when all of a sudden after the install it boots to nothing but the famous black screen with a white, blinking dash.So, what do I do? It was installed on a Dell Inspiron 9300 laptop, and I ended up completely wiping the XP drive to do it

I have just installed Ubuntu in a Windows Vista system. The installation seemingly went fine. After installation, system restarted to boot menu (grub?) where I selected Vista. Vista started fine. I restarted the pc from the Vista login screen. Now the problems started. At grub, I chose Ubuntu. It began to start up, made it through the Ubuntu logo with the dots, some splash screen or wallpaper came up and *bam* the computer powered off. Next I Wanted to boot Vista again. Grub came up for a half-second before power-off.
I tried to boot from the CD again to see about repairing grub or just reinstalling. The installer ran for a second before power-off. Next, tried BIOS boot manager to boot from the HDD again. Powered-off at the BIOS boot manager screen before I could choose where to boot from. Twice in a row. Tried to boot into BIOS to check settings for anything odd. Powered-off within 1 second after I got into the BIOS. Finally, I would hit the power button and it would turn on and then power-off instantly.
I unpulgged my Logitech VX Revolution mouse and the charger (it's fully charged and holding fine). I thought maybe the computer was hot (feels normal though), so I waited one minute. After that, I was able to boot from Grub to Windows fine. I restarted the pc from the windows login screen to try Ubuntu again. Got into grub and just repeated the same process from before with the same results. Nothing works. I waited one minute again, and I was able to boot into Vista fine. I am posting this from Vista with everything connected and working fine.
I downloaded the 32bit desktop version from the "enhanced download page." I burned the iso with the Toshiba DiscCreator software that came with the computer. I've used DiscCreator many times before with great success. Ubuntu was burned to a normal 80min/700mb Maxell CD-R. I'm afraid to reboot from Vista now and find that one of these times, I won't be able to get back in. I installed Ubuntu into an empty 9.77gb partition and formatted it as ext3. Used an empty 1.46gb partition as swap.
Here's my setup:
Code:
Satellite A215 Detailed Product Specification1
Model Name: A215-S5837
Part Number: PSAEGU-03801J
UPC: 883974072095 .....

Is there a program already set up to do this? Probably similar to WASTE (URL...), though waste's client is currently unsupported on the newest version of ubuntu (make error having to do with char* or something). Preferably windows and linux supported. Another thing that could be of use would be a local ssh chat. For example someone connects to my box either as me or as another user and runs 'hiben' and a window (or i ran a command or something and have a window open for it) pops up that we can chat in. Something other than single line messages.

I had Ubuntu 10.04 running fine. Then I got curious about NVIDIA XServer.
"ATI Technologies Inc RV380 [Radeon X600 (PCIE)]" - Video Card
I opened it up, clicked a settings change, and said OK.
It said you need to update your blah blah blah.
Then it said blah blah blah doesn't exist.
Then it said it would create it for me.
Then I said REBOOT!
Now I get a black screen of death.
The only way I can get anything to happen on my monitor that comes from this computer is to boot into the Install Disk and say "TRY UBUNTU".

I just upgraded from Ubuntu 10.10 to Ubuntu 11.04 Natty Narwhal and now I've got a purple screen of death. The download and install process all went okay, but when I restarted the computer through the upgrade dialogue to complete the installation process the system never came back online. When I turn on my computer it goes through the standard boot screen (F2 and F12 options shown while it boots the HDD, ODD, and wireless modem), and then it goes to a purple Ubuntu screen and doesn't do anything at all. I let it sit like that for 30 minutes before turning off the power and trying to boot again, but the same thing happened. I can press CTRL-ALT-DEL and the system will reboot, but nothing I know to do will get me past the purple screen and the Ubuntu logo. DI'm using a Dell Studio 1 desktop computer. It's got a 2.5ghz Pentium processer, 4gb of RAM, and a 400gb HDD. I don't dual boot, and Ubuntu is the only OS installed.

I am a Linux newbie and did one successful install Ubuntu 9.1 32 bit on my old desktop. Encouraged by that success (and the ease of it), this week I built my own system, which will be my primary system. I am trying to install Ubuntu 9.1 (AMD 64 version) and after the partition selection screen (I chose to partition the entire disk), I immediately get a white blank screen. Then nothing happens. I also tried with Ubuntu 9.1 32 bit, XUbuntu 9.1 64, Ubuntu 9.04 all had the same results.
Not sure if the hardware specs are required, but here they are:
1) Motherboard: MSI KA 780 G
2) Processor: AMD Athlon II X4 630
3) Memory: Corsair 2 x 2 GB, 800 MHz twinx 6400 c6
4) Harddrive: Hitachi sata 300, 1 TB
In desperation, I have started windows XP installation and that seems to progress fine at its leisurely pace. Its formatting the drive right now. During one of the attempts, it did install something*, since after that I see a new ubuntu partition after that. But when I boot from hard disk I get a black screen with cursor. I tried to search thru the forums and nobody seemed to have this exact problem, one guy got a white screen with cursor after a graphics card install, which is not the same. I dont want to go back to windows.

Has anyone managed to do a dual boot with W2K and a linux system without a resulting blue screen of death on the Windows partition? What I mean is only W2K and Linux, not one with XP. I think there is a difference in the bootloaders of XP and W2K.

My Firefox used to start instantly, or at least near instant, but since yesterday it took about 30 sec to launch. Opening subsequent windows is near instant, but once all windows are closed it would take a long time to open again.
When I open it up in a terminal, it has absolutely no error message, clean start up and shutdown.
I turned up the CPU clock speed from 1.2GHz to 2.0GHz and it doesn't seem to help. Other programs starts fine too, so I kind of ruled out performance issue.
Yesterday I also tinkered with compiz settings and also installed the cairo dock and some media codecs. But I can't pinpoint when does it happen exactly, I also struggle to draw any relationship if there is any. And if it matters Firefox is 3.6.10 and Ubuntu is 10.04.

I am used to doing very fast searches on the Mac. When I type into the search box in any finder window, the search results present themselves as I type. I am looking for the same functionality in Ubuntu. I tried Catfish but it doesn't have the speed I see on the Mac. Is there a way for me to index my drives so that searches are instantaneous, or are there any options I haven't explored yet?

I'm a Linux newbie and for my new job I have to do a lot of instant messaging to clients. They are on a variety of services, aim, icq, msn, myspace, facebook, yahoo, Google Talk, jabber, and .mac/ichat
Is there a good instant messaging client that covers most of these on one application? I am using Mandriva with KDE 4.2.
