Ubuntu :: How To Check Memory If Faulty
May 28, 2011
I bought a 2nd hand DDR 1GB memory chipset a few days ago and inserted it in to spare slot on motherboard. However unsure if memory is working properly because bios does not recognise it and neither does Linux but system does appear to run a lot smoother with programs loading faster. If there is a test I can perform to check if memory is working fine or simply return back to shop I bought it? Computer is a DELL Optiplex 170L mini tower system.

I wanted to read out a friend's windows hard drive, so I took the IDE connection from my CD drive and plugged it into the hard drive.
Now at boot time at the stage where it usually checks all partitions, linux complains about "zero length partition of that harddrive" and then stops giving me an emergency login.
Maybe that hard drive is actually faulty, even though I see all partitions correctly in windows. What can I do to make linux stop checking it? Is there a boot time option?
I suppose later I can manually mount a /dev/sdb or so device. I just have to figure out which
PS: what the easiest way to check which devices/partitions are available to mount?

I have decided to load the OS on a old HP Compaq DX2000 MT to see if its for me before putting it on my main machine.
I loaded Ubuntu version 10.10 last night everything was fine except I could not get my wireless adapter to work, I decided to connect via ethernet to get the latest updates and drivers.
After the updates and restart I now get the non executable memory error. when I enter
/usr/bin/check-bios-nx --verbose
I am told I have NX capabilities and should go to the bios and enable it. There is nothing in
the bios to enable as far as I can see. So I enter the command
sudo rm /etc/update-motd.d/20-cpu-checker

I have a weird printing issue with OpenOffice.
When I print from OpenOffice Writer, some characters are replaced by random characters. For example, this morning all capital "I"'s were replaced by "�" (German special character), a "J" was replaced by "t", and so on. But not all characters are replaced, most are correct.
In addition, the top of the documents are cut off, as if there is an overly wide top margin where the printer cannot print.
I exported the document to PDF and printed from Acrobat Reader, and everything was fine. No problems!
I'm running the Lucid release candidate (but the problem has bugged me for a while now), with a Brother HL2030 printer.

Thunderbird does not work properly in 10.04. Program windows come up blank with only the borders. Clicking on items on the menu often does nothing and when it does open a window like mail settings of fail to connect there is nothing inside the border. I have un-installed and reinstalled with the same results. All other programs seem to work fine. Could not find anyone with same problem. This is the same on several computers not just one.

I just managed to the one thing I wasn't supposed to do. I managed to mix up my drives and install Ubuntu on the wrong drive. I realized it seconds after starting the partitioning step but too late. It never started copying data but the new partitions are there. Is there any way of getting my data back. It's many photos aso that I don't have a backup of.
I don't want to "fsck" things up even more so I figured I'd ask if anyone has managed to recover from this.

I started #aptitude safe-upgrade and switched to another user. Gdm showed the error and hung down the system. So I did reboot. After reboot if I start totem I see such a result:
Code:
$ totem
ImportError: No module named gobject
** (totem:1978): WARNING **: Could not import pygtk
ImportError: No module named pygtk
[CODE]....
I tried to complete the upgrade with aptitude safe-upgrade, but it shows that all packages are up to date. I am afraid that some other packages are affected by this crash. How can I repair system?

I registered here and got Ubuntu a couple days ago. After setting up and connecting to my wireless LAN I went on the internet and uploaded the WINE source. However, after about 5-10 seconds of staying on the internet it all of a sudden stopped working (the internet stopped its connectivity) that is. And I was still connected to the wireless LAN. I tried to reconnect like most people would do, and I was not able to connect again (Would prompt me for password continuously to no avail). There isn't a problem on my windows 7 (I'm able to connect to LAN/internet).

I have an XD card with lots of pictures in it which suddenly stopped working, it gives me "card error" messages in my camera (and any other one) and it refuses to mount on my laptop's card reader (which does work in F11 for XD cards, I've tried other ones).So I'm trying to use some program to make an image of what's in the card, like ddrescue or dd_rhelp. But they all need me to mount the disk, which I just can't. I have tried to mount it manually, but I'm not even sure what device I should point to.
So my question is, how can I mount a faulty drive in such a way that any of these programs can make an image? Or maybe there is a smarter way to try to get my pictures back? (There are some non-free programs in Windows which may seemingly help, but I'd like to figure out how to do this in Linux).

I upgraded from 11.2 to 11.3 My task bar looks a little bit "strange" after the upgrade Here you can find out how it looks like [URL] You can see the American flag that (left) that appears a little bit strange as well as at the right side the kwallet icon to be over the time. As I expand the taskbar to the left and then reduce it to the right these strange things keep happening not to the same icons all the time but to some of them.

Is it possible somehow to remove these email addresses?

I'm having a variety of problems getting a new PC working properly, getting a reliable wifi connection is one of them. Earlier today I upgraded to 10.10 using my wife's account and download speeds were frequently at a reasonable 800kbps at times. This evening my son complains about the slow speed and a test shows 133kbps download with 616kbps upload. My own PC connected by wire to the router works OK.
A couple of days ago this problem seemed resolved when I installed Wicd but didn't configure it. I thought Network-Manager would have been removed but was still present. However, a downloads test showed 6Mbps. After today's upgrade slow downloads have returned.
I'm currently using this PC with a wifi link to the router and am connected to the Forum. If I hover the mouse pointer over the N-M toolbar symbol a window opens saying-
Wireless network connection 'Auto MYESSID'active:MYESSID(67%) If I right mouse click on the N-M symbol and select Edit connection... the wireless window reports that I was last connected 3 days ago. My own PC's wired connection window says against Auto eth0 that I've never used this. Both these are untrue. I wondered if having a hidden ESSID doesn't help? I'm left thinking that the rt2500 based wifi card needs replacing. We're some distance from other houses.

I saw that on every computer in which I installed LXDE on Debian 8 (the problem was not existing on Debian 7.8.0)
So I decided to use mate-desktop-environment but a brand new problem (always ) made his apparition when I try to use tightvncserver on a Mate desktop (no task bar, and memory growing GB after GB up to the memory explosion after 1 or 2 minutes with 16GB RAM -I will post another subject for that once I will know more things about it - since it is, after all, an huge problem causing the computer to crash if "reboot" our "vncserver -kill :1" is not quickly done)
But here talking about LXDE taskbar: others LXDE users, do you have this problem with the icons ?

opensuse 11.2 64 bits installed in a RAID1 software array. Everything worked smooth during installation, the system boots, the mdx partitions are in their places, did the upgrades, configured the way i wanted, booted several times... all ok. Then i wanted to test the RAID and since its RAID1 i just disconnected 1 drive and started the computer. All what i got is
GRUB loading stage 1.5
GRUB loading, please wait...
Error 21
Connect the drive back and the system works ok.
Disconnect the other drive, then i got
GRUB loading stage 1.5
GRUB loading, pleas wait...

Using Ubuntu Maverick and Totem, DVD playback has a slightly shaky picture and a little static at the top and bottom of the picture. Also, top level menus sometimes don't display, or the menu displays but movie won't play, or just nothing happens when trying to play a DVD movie. This problem is happening on two completely different boxes with clean installs. DVD playback seemed OK on Kubuntu and Xubuntu 10.10, as was OK on 10.04. Is this a known issue? And if so, is there a patch?

I am not sure if this is the correct section but it has to do with a faulty HD. So, the datacenter confirmed that the HD needs to be changed. They put it back and asked me when they should replace it. I told them to wait a bit.
Since then, one of the VPS hosted in this server is booting on "initramfs"
This is the screen. [URL] ....
fsck is not working.

I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.

I have a new system using an Intel DG451D main board. I have been trying to get a RAID 1 mirror set working as the main drive in this system and for some reason, my SATA drives - three of them all new have had their SMART data changed to show the drives as failing and in need of replacement. Eventually the drive reports failure to the degree that the BIOS no longer recognises it. When loading the Centos os I was getting differing results because of this issue. I am not sure if this is a hardware issue even - I know that the drives were all very much OK and brand new - no good now! Just putting a feeler out to see if anyone has had a similar issue or to see if anyone knows of any possible known causes for this?
Failing any explanation, can anyone suggest a good desktop style Main Board that supports RAID well for Centos 5.4? I plan to sue this as a small server system so graphics etc are not important here.
