I was wondering why the chached RAM doesn't decrease at the same rate or near that when scanning is done & the scanning software is closed as it increases during scanning ? When the cached ram reaches a certain point while scanning, the software crashes & I loose my scans
View 4 RepliesThere seems to be quite a craze about reducing the Ubuntu boot times to 10 seconds. I never really reached the 10 second mark.. for me it was more like 30 seconds from when I selected Ubuntu in GRUB to when I was prompted to type in the password in GDM. First of all, is this what is meant by boot time? Secondly, I know this already is quite a good 'boot' time, but just for the sake of tinkering around, is it possible to reduce the time that elapses between the GRUB menu and GDM?

View 3 Replies View RelatedI tried to install Portable VirtualBox using wine and even though I installed it on my /host/ folder (with 19 gb free) it downloaded some massive file on my Wubi installation (with 60 mb free) and now I am down to 3 mb left on Wubi and I can't find the massive file that it downloaded. Tried using the disk usage analyzer but nothing came up. Windows is unbootable so I can't use it.
Before this, Ubuntu would constantly decrease the amount of disk space I had free for no reason as well. It would jump from 120 mb one day to 50 mb.I moved my documents to my Windows folders but the disk space only stayed at 100 for another day or so before it went down again. apt-get auto/clean, localepurge, and deborphan are completely useless and there's something else going on behind the scenes here that I don't know about.Using Ubuntu Jaunty.
I am runnin Ubuntu 9.10- the Karmic Koala on acer aspire laptop. since everythin in this netbook is crap. so I hardly can see movies that so much going on in them( when so much happens, the screen freezer for a while therefore i miss the most interesting bits) I used kinda every players. the only one that works for me is mplayer since it does not require high spec it works good but it has its own costs. if I use mplayer then i have the porblem of the sound (eg i can hear stuff before it happening) I am now just wondering if there is a way to decrease the quality. I really dont care if i have great quality or not as long as i can c whats happening ( at least for this netbook anyway)
View 1 Replies View RelatedI'm trying to decrease the tcp TIME_WAIT state which, from what I understand, occurs on the host that initiates the closing of a socket by sending a packet with the FIN bit set. Most people say to change /proc/sys/net/ipv4/tcp_fin_timeout to a lesser value. I have tried this many times and it makes no difference. The TIME_WAIT's still linger for ~ 60 seconds. This link says that it actually adjusts the FIN-WAIT-2 state and I think they're right.[URL]
Quote:
/proc/sys/net/ipv4/tcp_fin_timeout
Time to hold socket in state FIN-WAIT-2, if it was closed by our side. Peer can be broken and never close its side, or even died unexpectedly. Default value is 60sec. Usual value used in 2.2 was 180 seconds, you may restore it, but remember that if your machine is even underloaded WEB server, you risk to overflow memory with kilotons of dead sockets, FIN-WAIT-2 sockets are less dangerous than FIN-WAIT-1, because they eat maximum 1.5K of memory, but they tend to live longer. Cf. tcp_max_orphans.
Here's what the netstat man page says about these two different states:
Quote:
TIME_WAIT
The socket is waiting after close to handle packets still in the network.
FIN_WAIT2
Connection is closed, and the socket is waiting for a shutdown from the remote end.
how to actually decrease the TIME_WAIT state?
Desperate to reduce RAM usage of my tiny VPS running Ubuntu 9.04 and Apache2.2.11, here I saw that:
On Linux, each child process will use 8MB of memory by default. This is probably unnecessary. You can decrease the overall memory used by Apache by setting ThreadStackSize used by Apache by setting ThreadStackSize to 1MB in.
So I tried to give the suggestion a try. But when I append:
ThreadStackSize 1000000
in my /etc/apache2/httpd.conf <IfModule mpm_prefork_module> directive, and restarted apache, it failed with this message:
Invalid command 'ThreadStackSize', perhaps misspelled or defined by a module not included in the server configuration
So I figured out that the relevant modules are neither enabled nor available on apache2. Now I am wondering whether there is a way to decrease the ThreadStackSize without the need to compile apache from source? If not, what should I do?
I'm having a huge performance decrease when I'm on Battery Power. Plugged in this thing runs AMAZING, HDMI with HD video, I can run compiz 3d, full desktop advanced effects, HD video from ....., you name it. Just when I pull the cable out it slows down. I tried disabling ATI powerplay but that didnt help.
Is there a way I can toggle the performance, so that I can get "plugged in level performance" even when i'm on battery power? I'm not too bothered about how long the battery lasts. I'm usually always near an outlet.
Currently, I have on internal HDD 160GB in size. 20GB are for windows XP partition and the rest is assigned for ubuntu partition(s?). i want to make it now more equal in size, but how can i do that? I'm using ubuntu 11.04...
View 3 Replies View RelatedI have two questions:
1- Does Linux operating system decrease the original size of the HDD? because first I was only using a Windows 7 Ultimate on my Laptop Lenovo G550 4446 the D:/ partition size was 140 GB Free of 190 GB.. After I installed the Linux ubuntu along with the other Windows 7 I found the D:/ partition size became 68 GB free of 122 GB... Why the hell the size decreased?? Did the HDD destroy?
2- How can I hack Wireless Network of type WPA2/WPA or WEP using the linux? I have heard that I can do that using Shell Konsole, but I can't see Shell Konsole in my Linux ubuntu 10.10... Is it required to be installed over the internet or something, or if it is already installed within the operating system, can you tell me where I can find it?
I am new to Fedora, and I noticed when I opened my home folder that I only had 54GB. My HD is 120, and when I used the disk utility, I noticed that 64GB are in ext4! What?! This was not a problem in Ubuntu, so why has it happened now? Is there anyway I can decrease the size of ext4 and give some of it to Fedora?
View 4 Replies View RelatedInitially i was on kubuntu 10.10 with kde 4.5.x and i realized that animations throughout kde stunk. For example, the kickoff menu would raise and lower very jerky. So thinking this was a kubuntu or even a kde 4.5.x problem, I made a switch to opensuse 11.3 and kde 4.4.x. After install i noticed that all animations, including the menu raising and lowering, where very smooth and crisp (like they should be). I later realized I wasn't even using all my hardware's power so I put my two gtx 460s in SLI=auto. After a reboot I realized that once again all animations got jerky again . This leads me to believe,and for good reason, that kde's visual performance is degraded with SLI enabled.
Ps: installed kde 4.5.2 and still same problem
I am running Arch on a Sony Vaio 64-bit computer with an ATI Mobility Radeon HD 4650 graphics card (xf86-video-ati installed).
I am attempting to decrease screen brightness; I have tried editing /proc/acpi/video/VGA/LCD/brightness (gives me: "write error: Invalid argument") and xbacklight -set <value> (gives me: "No outputs have backlight property").
Anyone know how I could decrease LCD brightness?
I have an issue with few servers. All have OEL 5.5 and various versions of oracle (mainly 10g something).
I've noticed on one machine that amount of free memory is slowly decreasing. When it comes to less then 30M, application has problems. Ive tried adding mem on this machine (virtual), and it behaves the same.
The same is on physical machines I have simmilar, if not the same config. Variations are with physical memory installed, and it does not matter if servers have 2G, or 8G, free -m gives around 30 free
It does not swap, and does not make some big issues on other machines, but on this one, application that uses this DB timeouts the user. Is there some chance to check what is creating this issue?
P.S. I've tried with DB admin to check something related to oracle itself, bit when we shutdown instance, Oracle frees 1.5G allocated to him, but nothing else. Will try testimg a bit more, but any thought on this is usefull. This is production server, so no big issues can be done. Will try to copy it to other hardware and do some testing, but then no App server available to attack it.
On F12 and sure need to upgrade. Way back when I first had a bad disk on the "system" disk that was 80G, I only had a 200G lying around. Next time that happened my other 200G wasn't "big" enough it said, so I put a 500G in there. Now it seems I got more bad blocks etc but I need to lower the size 'cos I don't want to put a 1Tb HDD in there. My question from all of this is, how do I decrease the image so I can put it all on a smaller HDD?
Used space on the system disk's partitions is about 30G, so an 80G disk should be sufficient. What I can think of is that I need to "move" all data to the "beginning" of the HDD, then make an image of it but and the entire disk, just the data. I've tried that with no luck since the image seem to get as big as the HDD, hence why I always needed to increase the HDD all the time.
Lately I have noted a decrease on the performance of my Ubuntu Karmic Koala 64 bits installation. It takes longer times to open applications and documents and sometimes the windows fade to grey and I have to wait. Can anyone give me some hint on where to start looking for a solution?

View 2 Replies View RelatedIn /proc/scsi/scsi, we can see the scsi host no. (scsi identifier no.). for e.g. Host: scsi4 Channel: 00 Id: 01 Lun: 00 In above e.g., scsi identifier no. is 4. Whenever we modprobe a particular module associated with scsi devices, we can see new entry in/proc/scsi/scsi with a greater identifier no. When we do rmmod on that module, the entry from /proc/scsi/scsi wipes off but still the counter of scsi identifier no. doesn't decreases. is is there any way to reset or decrement this counter so that next time when I do modprobe on scsi related module, it will assign no.s starting with 0 ? I found that during registering a scsi device, scsi_register() method gets value from "next_host" (which is a static int initialized to 0) and then increments next_host counter. Also, during scsi_unregister(), it decrements next_host counter. rmmod internally calls scsi_unregister(). So, if it is true then why the scsi host id. doesn't decrement during rmmod?
View 2 Replies View RelatedWe have recently built some RAC (OS:RHEL55) servers and after the Oracle guys have installed their application, somehow the directory / is using the maximum space. I contacted the Oracle team & they say that their RAC installation doesn't create any files in the / directory. This is the o/p of '/' directory file system:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/datavg-vol2 498M 382M 62M 88% /
Also, when I checked the file sizes, I found that the following files were taking more space:
/etc/selinux/targeted/modules/active/
-rw------ 1 root root 17M Nov1 base.linked

I don't know what these files are doing there, when I did a cat and cheked, I found the files containing this data:
nf_tre--
stem_dbusd_var_run_t...and some stuff like this Unable to decide whether or not to remove these files. Also, is there any way to find out what files are taking more space and whether they can be deleted or not? in order to free up some space in the / direcoty. As there are 10 RACs that we've build, I got to do something to fix this for all of the 10 servers.

I just installed Ubuntu 9.10 I have ATi HD5700 and its Catalyst drivers downloaded from http://ati.amd.com
The monitor is Hanns-G HH251 (25", 1920x1080@60 max) I cannot make either "Display Settings" or "ATI Configuration" to show the refresh rate of 60 Hz as available. When I change the resolution to 1440x900 then I can pick 60 (but obviously I don't want that resolution). However, if I pick 1920x1080, the only two refresh rates available are 25 and 30 Hz, causing the image to flicker and whatnot.
