Hardware :: Gentoo Don't Detect Full Ram Memory / Resolve This?

Jul 22, 2009

I can't make Gentoo recognize my 2 rams of 512MB, It's seems to recognize just 891900 KB code...

I tried to recompile the kernel with 4gb ram support but I couldn't find the "High memory support" in "Processor type and features", I think because I have a amd64 OS.

Kernel version: linux-2.6.30-gentoo-r3
RAM: hynix 512MB HYMP564U64CP8-Y5 (Specification are here in PDF)

Ubuntu Installation :: Mythbuntu System Hangs After Regular System Update: "out Of Memory" Errors

Aug 4, 2010

I have Mythbuntu 10.04 installed on an exclusive HTPC and working great... until tonight. After letting the system update some packages (161 packages if I remember right), I suddenly have an issue where the graphical system won't start. After researching I found three error messages that might be causing that.

1. At the start of splash screen I see "UUID=xxxxxxxCD7 not ready yet or not present" I checked in /etc/fstab and found that this is the swap partition. I don't remember seeing this before so this could be the culprit.

2. I'm not at the computer in question right now but I saw a Plymouth error about "mountall" and then the message "plymouth command failed". Not sure if this could be the main error.

3. after a while (usually ca. 1-2 min) I receive thousands of errors of the kind "out of memory"... "kill process XXXX" (process vary wildly e.g. dbus-daemon, mysql, etc)... "process killed"..."respawning"

After error 3, I'm not able to switch to graphical console (ctrl-alt-F7). If I was in the graphical console at this moment, I simply can't switch to the CLI console. I'm always afraid of updating my system since I've seen lots of things breaking afterwards (usually the proprietary graphic drivers) but this is really strange.

Ubuntu :: "Couldn't Detect Any System Tray On This System"?

Jul 4, 2010

Programs like aMSN, and controlling music volume, etc are gone in the upper-taskbar/panel. I think I accidentally managed to delete the whole upper panel, and created a new one. Still the programs I start up which suppose to appear in the upper panel, don't appear there. Any idea how to fix this, or to add those functions to the upper panel?

Debian Hardware :: System Can't Detect Other Graphics Card

Jun 12, 2011

I have two graphics cards in my computer. One is a crappy built-in nVidia GeForce 6150 SE, and the other is a high-end (as of 2008) GeForce in the 8000 range. I would like to use the latter, but I can't get anything to detect it. Testing which is in operation is easy: they have separate video outputs. I've tried changing the BIOS settings, but to no avail. I'm stumped. Could it be that my other card is dead? How could I test it? I'm fairly certain that it worked back when I used Windows, as I remember having to use my DVI-to-VGA converter (the other card's outputs are all DVI).

General :: Make App Detect When System Time Has Changed?

Jun 9, 2011

I need to write a small application which needs to detect if the system time is changed by an another application/user and perform some action as soon as it is detected (maybe log the data that time has changed, along with info about which application/user changed it).

How can this be achieved?

I have good programming experiences in shell script, c and beginner level in python.
I don't need to know when it was changed, just need to know who/what changed it.
The system uses NTP to sync the time, but it is also possible for anyone/any application to change the time(for eg: using the simple "date" command as well).

Networking :: System / Script To Detect Outgoing DOS Flood?

Oct 16, 2010

I run a Centos server that quite a few people have access to. I trust every user on the system, but i've had problems before like one user's account gets hacked and someone starts using my box to DDOS. Each user has their own ip.. And I would like to write a script or use an existing solution (if one exists) to monitor number of tcp/udp connections each minute and see if it's unusually high. I don't want it to stop the flooding or anything, I just want to be notified by email or something.

Ubuntu Installation :: Cannot Reinstall - System Doesn't Detect Its Own Screen ?

Jul 12, 2010

I'm new to linux and having a lot of problem, and I would really apprecaite the help. It all started when I connected my laptop to an LCD. Since then, my system doesn't detect its own screen. So I have to escape as the start of reboot and go to a recovery mode and select failsafe screen. Ubuntu then set to lowest graphic mode. It's no way to keep a set up for the long run. I've tried to reinstall Ubuntu from a CD but that doesn't work. .

Fedora Hardware :: Cannot Use All Of System Memory?

Jun 6, 2010

I just installed Fedora 13 onto a "new" (to me) box, and everything seems mostly fine, except that I only seem to be able to use about 900.2 MiB of 991.4 MiB of RAM memory, according to System Monitor. I haven't set up a swap partition yet, so the problem became very, very, very obvious. When I get to about 890 MiB usage, everything goes very quickly downhill, locking up, etc. The peak I saw was 900.2 MiB. What's going on? Does this have anything to do with the system being 64-bit? Might the memory be bad?

Hardware :: It Is Possible To Damage System Memory By OS?

Mar 29, 2011

I have a new lenovo thinkserver hardware. I was configuring my newly installed kernel (slackware 13.1 - kernel 2.6.33.4) maybe to weeks now. I was testing the configuration of the kernel parameters.Suddenly out of the blue my BIOS started to report memory error. I have 6 Fully buffered memories in pairs. Four has no advanced ECC and two supports ECC.It is possible to damage the memory by some wrong kernel configuration???I cannot believe that this is possible but I cannot see any other explanation how can a two weeks old hardware get wrong.

Fedora Networking :: F12: Broadcom Wireless Does Not Detect Any Network On X86_64 System

Dec 8, 2009

I have a Broadcom Corporation BCM4312 802.11b/g (rev 01) wireless card. I installed these packages:

broadcom-wl-5.10.91.9.3-1.fc12.noarch
akmod-wl-5.10.91.9.3-3.fc12.6.x86_64
kmod-wl-2.6.31.6-145.fc12.x86_64-5.10.91.9.3-3.fc12.8.x86_64

[code]....

uname -a says:

Linux boz.alafkhar 2.6.31.6-145.fc12.x86_64 #1 SMP Sat Nov 21 15:57:45 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

and:

# lsmod | grep wl
wl 1278432 0
lib80211 6436 2 lib80211_crypt_tkip,wl

[code]....

My networkmanager understands that the card is installed. But it can not find any network. Also iwlist scan gives me no result. I did not have this problem on earlier fedora releases. Recently I upgraded to F12 from F11. I should mention that I have another USB DLink wireless card and when I plug it, everything works fine with that card. I also tested wl_apsta driver using fw-cutter. I did not work neither.

Debian :: Memory Usage On A Squeeze System?

Mar 16, 2011

I use a Debian Squeeze system running off a flash drive, i.e. based on a custom Live image running in persistent mode. It runs great and I am grateful for the existence of Debian . However, I have a question. A lot of the machines I use this pen drive on are quite old, often with 512 MB RAM and old processors. I specifically built my system using XFCE and lightweight apps off an initial live image using the standard-x11 package list (basically just Xorg with drivers and the base system). At first things ran very well, blazing fast even on the oldest systems and could comfortably run Firefox along with LibreOffice side by side (I need LO as all of my colleagues use Word docs, often with track changes, which Abiword can't handle properly). However, over time, I've found that memory usage has risen, tot he point where Firefox is now automatically killed on the older systems every time I start LibreOffice.how does one figure out why memory usage is going up? I've checked for inessential services and turned them off with "insserv -r". I've used only lightweight apps, as mentioned before. Are there other general tips on reducing memory usage?

General :: High Memory Utilization By System?

Nov 11, 2009

I have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)

It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb
bfe46000 1768 rw--- 00000000bfe46000 000:00000 [ stack ]
ffffe000 4 r-x-- 0000000000000000 000:00000 [ anon ]
mapped: 33384K writeable/private: 3352K shared: 20504K

But when I run the top command, it results as below:
Tasks: 163 total, 1 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.9% us, 4.9% sy, 0.0% ni, 93.3% id, 0.8% wa, 0.2% hi, 0.0% si
Mem: 3895444k total, 3163192k used, 732252k free, 352344k buffers
Swap: 2097144k total, 208k used, 2096936k free, 2487636k cached

Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.
