Ubuntu :: Update Kubuntu Simultaneously On Ubuntu Machine Cause Slower Performance / Conflict In Programs
Jun 7, 2011
I recently installed the KDE (Kubuntu) desktop via Synaptic Package Manager. I have a few questions about this: Do I have to update Kubuntu when I update Ubuntu in October, or will it update on its own? Does running Kubuntu simultaneously on an Ubuntu machine cause any issues (slower performance, conflict in programs, etc.)? How do I uninstall Kubuntu if I decide that Ubuntu works just fine for me?

using mint 10, now after updates my system is barely working. The programs were no longer showing in the task bar, and the system was running much slower.
[code]...
This repeated over and over again. My temperature was never to high 40-55, and I found a suggestion to update my kernel to 2.6.37-020637. After doing so there is no longer the thermal limit exceeded error but the computer is still running poorly. The system is slow and again no programs are showing up in the task bar when open.

I am running openSuse 11.2 (32-bit), my CPU only supports 32-bits. I have a hardware RAID device. My system has 4GB of RAM. When I configure my system to only use 3GB, 2GB, or even 1GB, using mem=1024M in grub, my RAID performance is much better then when letting my system use the default 4GB available.Can anyone explain to me why this is? Is there anything I can do, i.e. kernel configuration, that will help performance when running with all 4GB enabled?

I'm not sure if this is possible, but it seems like it should be, since a linux box can act as a router. I want to be able to use two separate network cards simultaneously (one wired, one wireless) in separate programs.
Example: I want to browse the internet on my wired eth0 interface, and simultaneously run bittorrent on my wireless wlan0 interface (which is connected to an entirely separate network). If I need to use multiple user accounts, then that is fine.
P.S. I'm running Ubuntu 9.04

I have two ISP Connections from different Providers BSNL and Sify. Both are 1MBps. In my Office Now we are using Sify for Only one Machine and BSNL is configured in wifi router. But Often BSNL network is in problem. So we have planned to use both Sify and BSNL simultaneously. what we have to do is to Make some arrangements either in cabling or in configuring we have to use both the connections simultaneously. without hassle so that the employees will always be on-line. and they may not know in which ISP they are browsing. But the internet should be available always.
We have two servers which has running Redhat 5.5 with two Onboard Ethernet card so totally Four Ethernet cards. And we are using Only linux such as fedora, ubuntu and CentOS in our Office and not windows. And all are connecting to internet by wireless. So please give some ideas to use any linux machine as router or something else that would balance the two ISPs equally, that is if one ISP is down then the other should take up automatically without doing any manual configuration and without buying any proprietary software or any hardware.

1) Disable blur effect in System settings>Desktop effects>All effects.
2) Press Alt+F2 and type oxygen-settings. Then go to "animations" tab and uncheck "enable animations". Also under "Window decorations" uncheck "enable animations".
3) System settings>Application appearance>Style>Fine tuning tab. Choose "Low display resolution and low CPU"
4) System settings>Desktop effects>Advanced tab choose fastest texture filter.
5) If your desktop effect are disabled on every reboot then you'll have to disable functionality checks. Go to System settings>Desktop effects>Advanced and check "disable functionality checks".
6) If you are running opensource drivers (ati or intel cards) you could try to improve your desktop effects with updating your drivers from xorg-edgers ppa. If updated drivers doesn't work better, you could safely downgrade your drivers to official ones with ppa-purge comand.
Code:
sudo apt-get install aptitude
sudo apt-add-repository ppa:xorg-edgers/ppa
sudo aptitude update
sudo aptitude install ppa-purge
sudo aptitude safe-upgrade
Then reboot. If updated drivers do not work better you can downgrade them:

I want to build deb packages for two versions of same product that can be installed on the machine simultaneously. The source folder structure for both the packages have a common folder needed by both the versions. So i need to keep the common folder till both the versions are removed from the machine.My problem is that i can't install both the versions at the same time, i.e i have to uninstall the installed version and then install the other version. After installing one version, if i try to install another version, an overwrite error comes up. is there any option in dpkg for overwrite? Or is there any way to partially uninstall a deb package?

I've been running 10.04 since it came out basically and my internet connection has been fine. After I got the last set of updates that came up on the update manager (which if I remember mainly contained an updated version of the latest kernel and a couple other files) my internet connection speed went from a decent browsing speed and file transfer speeds between 80-200kbps to an almost dialup browsing speed to file transfer speeds of a about 7.5kbps its very significant and very annoying it took 20 minutes just to make this post.
Also I've already tried changing my ipv6 settings.

I just installed Ubuntu 10.04 on a laptop that was given to me. It is having a lot of lag issues,especially when playing videos and visiting websites using flash. It's an Intel Pentium 4 2.4GHz machine. I think that it should perform better because I had used and AMD Sempron 2.0GHz machine with Ubuntu before and video playback was much better than this. I'm thinking that my problem is the graphics card driver. Here is the card that this machine has:
Code:
:~$ lspci | grep Radeon
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon IGP 330M/340M/350M
The AMD machine was using a VIA graphics chipset.
I used the command "Xorg -configure" to create a xorg.conf file, hoping that might help. But it didn't. Here it is:
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code]...
Is there any tweaking that I can do in the xorg.conf that might help? I don't know which of those options I should set. I also tried changing the driver to "ati" but that did nothing. found some info for settings with "man radeon", I'm going to try some of those out.

If I have only 1 physical WLAN interface, is there some hackery that can be done so that it can be a client of an existing access point and at the same time also act as an access point for other clients? I have an existing 802.11g ADSL router, and I'm going to be building an HTPC which will have 802.11n. My laptop also has 802.11n, but at the moment it only connects at 54Mbps because thats what the AP supports. I'd like to be able to have the HTPC be a client of my ADSL router, but have my laptop be a client of the HTPC, so copying files to it will be faster.

I have F10 x86_64 installed on my desktop. When I update the packages, everything works well, except curl-7.19.4-6.fc10.x86_64 which conflicts with the installed curl-7.18.2-6.fc8.i386 (Fedora 8!). The problem seems to be that my repo list does not have the info about the F10 i386 repository. This is the report from "yum repolist"
------------------------------------------------------
Loaded plugins: refresh-packagekit
repo id repo name status
adobe-linux-i386 Adobe Systems Incorporated enabled: 17
fedora Fedora 10 - x86_64 enabled: 14,303
[code]...
I don't want to simply remove the f8.i386 package, because it'll take away a lot of other i386 packages that I'm sure I'll miss in the future (nspluginwrapper- .3.0-2.fc10.i386).
The other solution seems to be updating the curl-***.i386 package. However, I'm somewhat embarrased to confess that I don't know where to find the repository information...

Well I'm kinda a paranoid person, and got bored and ran a port scan from 0 to 500000 and turned up some interesting results, I was wondering how I find the programs tied to each open port. Its my computer and I'd like to very well know what programs are needing these ports and for what usage.

I have been running F11 for some time now. I install updates regularly and to this time have had no issues. Now it comes up with error.
Code:
[root@red 2305 ~]
$ yum update
Loaded plugins: protectbase, refresh-packagekit
0 packages excluded due to repository protections
Setting up Update Process
Resolving Dependencies
--> Running transaction check .....
--> xorg-x11-drv-nvidia conflicts with xorg-x11-drv-catalyst
Error: xorg-x11-drv-nvidia conflicts with xorg-x11-drv-catalyst
Error: xorg-x11-drv-catalyst conflicts with xorg-x11-drv-nvidia
You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
[root@red 2306 ~]
I do not believe that I even have the 'xorg-x11-drv-catalyst' mentioned here installed:
Code:
[root@red 2315 ~]
$ yum list all | grep installed | grep catalyst
[root@red 2316 ~]
This returns nothing so why the error?

Im experiencing a strange problem with 10.04. When it first boots up its reasonably quick (as snappy as Gnome ever has been) but after its been running for a day or two it gets ununsably slow and has to be rebooted.
I dont see how it can be anything to do with my hardware as it runs OK when first started. Ive monitored RAM usage and it doesnt seem to differ much. There's always the same amount unused.

OpenSuse 11.2
LXDE (Latest version)
It used to have a lightening speed. But now every application is taking few seconds to start, even on Konsole, the commands take some seconds to get typed ! (I literally have to wait for cursor to move and commands to get typed on Konsole). Folders are taking some seconds to get opened !
I rebooted the computer but that proved to be useless.
Here the ps output:
Code:
anisha@linux-uitj:~> pstree -Apuh `id -anisha`
id: invalid option -- 'i'
Try `id --help' for more information.

I have a multi-threaded app using pThreads that runs great under Windows on my 4 core machine - all four cores get maxed out processing parts of a large file. I recompiled the same code to run on Red Hat linux on a 64 CPU machine - but from I can tell when it runs - it gets stuck on one core. "mpstat -P ALL" shows the cores are barely loaded. I have tried sched_affinity, sched_priority and SCHED_FIFO - nothing has helped. Any ideas on getting more performance?

recently I have installed a brand new machine with 11.2. Machine boots so incredibly fast so I decided to upgraded another older machine from 11.1 to 11.2. Upgrade went fine but old machine boots significantly slower. On new I see message "doing fastboot" and few seconds later KDE starts loading. Amazing. On old I just experience regular boot, speed is comparable to old 11.1.What am I missing after upgrade? Same kernel, almost same set of services. Both machines are pretty regular PCs/x86_64, however old one have faster/better hardware (more cores, more GHz, more RAM, 2 disks in software raid-0).

Ive successfully set up Ubuntu on a desktop computer I got for free (because it�s RAM was half destroyed by a virus and the owner got a new one). I don�t have this computer connected to the internet but I can get the internet on my laptop�s built in wifi (from some random neighbour who has an unsecure WLAN). So, to install programs on Ubuntu I have to download the .deb or .ter.gz files from the laptop (winXP), copy them to a USB drive, transfer them to the Linux machine and install. Problem is, none have worked so far:

I have an issue with the manner in which Network Manager is configuring the network and short of ditching Network Manager I can see no solution.The issue : Getting a machine to update its machine name in the DNS serverSounds simple doesn't it I operate a FreeBSD based firewall / DHCP / DNS server, using a default Network Manager DHCP configuration the Fedora clients do not register their names with the DNS server when they obtain an address.
I have traced the communications with Wireshark and the Fedora clients are NOT supplying the PC's hostname as part of the exchange so this is NOT a DNS server configuration issue. If I uncheck the option 'Automatically obtain DNS information from provider' under the DHCP settings the Fedora clients DO register the hostname that is put into the Hostname (optional) databox. They do NOT however store the DNS server IP address or any other records defined by the DNS server.
Is there some hidden settings or is this a bug because it isn't acceptable 'DHCP' behaviour if it isn't possible to automatically set DNS server IP addresses and at the same time register the hostname during the DHCP negotiation. Before it is said I know I can use a fixed DNS IP address but am not prepared to long term, I am also not prepared to define the Fedora clients with a 'static' IP. I am similarly not interested in playing around with scripts or any other such 'frigs' to achieve what should be a standard activity - registering a host with DNS during the DHCP negotiation.

I am behind NAT using private IPs like 172.x.x.x in my lab. I need to access programs from other machines which are also behind NAT. What is the syntax of ssh command that i can run? Because when i make connection within one LAN for example:ssh -X 172.x.x.10 to 172.x.x.3 it works fine. I can access programs like gedit, firefox etc. But when i try to do the same on the machine that are behind NAT then i get this error;
