Ubuntu :: Why Is Desktop So Heavy - Ram Load From 275mb To 120mb
Mar 13, 2010
I installed openbox and pcman on my old desktop and was able take the desktop ram load from 275mb to 120mb. (openbox, pcman, kupfer, gnome-panel) I was so pleased with the increased headroom and performance that I wanted to do it on my macbook. Usually my macbook has as desktop ram load of about 350mb... which I find excessive as that is heavier than OS X. That's running gnome, nautilus, compiz, and gnome-do at startup.
I performed a similar procedure today to create the same setup on my laptop and... strangely, my ram usage on the desktop is still close to 300mb! I've brought up system monitor and added up the ram of all the processes it detected myself and it only added up to about 50mb. How is it that my desktop is still so heavy in a minimal environment?? (both machines are Karmic 9.10, by the way. The desktop is hardwired to the internet while my laptop uses Wicd)

i run right now digikam and rebuild my thumbnails. It seems like that this task takes a lot of cpu power and its not digikam itself, rather xorg takes the load. Is this right? I just wonder.

I just want to tell laptop users how they can protect their hdd from heavy load cycle count (spin up/down of the hdd) when using battery.If you are not sure then just type this command several times in interval of 1-2 minutes, and you will see how much the hdd head spins down, and up: Code: sudo smartctl --all /dev/sda | grep -i load_cycle.Change /dev/sda with appropriate hdd path for your pc.

I have recently begun contributing to the Folding@Home distributed computing project. Due to oversights in the application's design and to process the most advantageous work units, I need to run this command line app through wine. The application is very CPU/RAM intensive, but it does not put much load on the hard drive. It is multi-threaded and uses up to 100% of all 6 cores in my machine. I run it with a "nice" level of 19 with hopes that it won't slow down my normal desktop use.
Here is the problem... when running this setup, my system will frequently freeze for a fraction of a second and then resume. With the more complicated work units, this can happen 1-2 times per minute. During the freeze, the mouse will stop moving, videos stop playing, music pauses, etc. The system is completely unresponsive. However, each instance only lasts for a very short time. Since this happens so often, my productivity is negatively impacted (and it's very annoying).
I previously ran the native Linux version of F@H without this problem, but that was also processing much less complicated calculations. I have tried with wine 1.2.1 and 1.3.5 with the same results. The application does not have problems running on Windows. It has been suggested that the current Linux CPU scheduler is to blame, but is there anything I can do to resolve this now or work around it?

this is with both network manager and WICD, a problem i've had since i got ubuntu - multiple wipes and reinstalls the wifi is supported out of the box, the problem i've randomly run into since installing is, it will randomly stop detecting networks "no networks detected"
i've noticed over time as this as been happening, that it usually happens whenever there is a high load - multiple videos going on multiple tabs, videos queued up etc. its never happened during regular browsing - theres always a lot going on when it happens, almost like it collapses. the only way to fix this, is to quit the manager - shut off the computer (restarting doesnt work) and then it comes back after

My LAN has 2 PCs installed, Ubuntu 10.04 and Windows XP. I run the server on Ubuntu, and client on Windows XP. Because I am doing stress test, so the client will keep sending tons of packets to server.
The strange thing is: After few seconds, the client program crash because of insufficient network buffer, the server is still ok. But after that I cant connect Ubuntu PC anymore until I restart it. And I check the router, the led for the Ubuntu PC is always ON (not blinking), look like it is jam already.

Is there a way to switch a internal card slot from /dev/mmcblk0** to /dev/sd** ? I'm backing up (via rsync) an ebook directory (1.9gb) to sd card and get massive i/o errors, card turning read-only,etc. This is via a built-in slot on a toshiba laptop. When I use a card reader, the card attaches to /dev/sdd1 and all is fine.
This is a new Sid install. The laptop's card slot worked fine under Ubuntu 9.04 and still works if the amounts of data are small. All I can figure is that the mmcblk device dies under a heavy load...

There is a tool appeared in repository called ktune; The purpose is to adjust some sysctl.conf settings to improve server speed on servers with heavy load. What is this tool for if one can achieve the same with the configuration file added to system startup? Or ktune is just such file?

I'm running Fedora 15 with Gnome 3. I installed Gnome-Do using 'yum install gnome-do'. I opened it from the Terminal by typing 'gnome-do' but I keep getting an error message that says
Could not load desktop item: libgnome-desktop-2.so.17
Gnome-Do opens but it doesn't display any application I search for and when I try opening the Gnome-Do preferences, it quits.
I installed gnome-desktop-2.32.0-8.fc16.i686.rpm from here: [url] and then installed Gnome-Do. Everything works fine now.

I have installed Fedora 13 sucessfully and rebooted my computer for its first run of Fedora. When it comes time to load the desktop I only get the desktop and nothing else. I noticed that my mouse can run off the side of the screen on the left or right. I've tried rebooting and the only thing that changes is which side the mouse runs off.

I have an Dell 755, and I have installed Ubuntu 10.4 desktop on it, everything works fine. I have it auto login, and run Azureus/Vuse at startup (so it can be a headless Bit Torrent server), it works perfectly. As soon as I try to go headless (no keyboard/mouse/monitor) the machine boots fine (I can SSH / FreeNX to the machine) but none of the GUI/apps load. What I think is happening is that when it boots without a monitor attached it does not load any of the X11 stuff. I need it to. It worked in Ubuntu 9.04 just fine, but now with 10.4 it is a no-go. Does anyone know how to force the X11/GUI to load when there are no monitors/hardware attached? This is the one thing standing in my was of getting Windows out of my house.

I've just upgraded a Kubuntu box to 11.04.It was configured to load the desktop without a login.The problem now is that it loads up to the first four icons on the KDE splash screen, but never completes the last, large KDE icon. It hangs. Anyone know how I can get around this?I managed to boot into the desktop by switching the desktop effects from by using an alternative GUI. But it begs the question, desktop effects worked fine in 10.04 and 10.10 on this PC. Why not 11.04?

What I meant is after trying to load Ubuntu 11.04 Desktop from USB, my laptop directed loaded into a Grub bash like interface. Seems like I could manual load Ubuntu by hand, but the Grub interface are so different, I have no idea how to do that.
I tried 'boot', it ask me to load Kernel first, but how can I found kernel in my USB drive?
BTW, what I am trying to do is install Ubuntu 11.04 though UEFI.

I recently began using Ubuntu 11.04, having a dual boot setup alongside Windows 7. Everything worked perfectly fine until the last update of Ubuntu occurred. After the update I rebooted my system (as you do) to "Ubuntu, with Linux 2.6.38-10-generic." When I do this it does one of two things: a) the Terminal loads and the cursor sits there blinking boringly achieving nothing and doing nothing the OS does not get very far into loading. Or b) A number of checks run automatically then pause and it goes nowhere and I'm left with a screen full of System checks. So, what I do is I load a previous version of Ubuntu "Ubuntu, with Linux 2.6.38-8-generic" and this loads no trouble.

I had finally go tmy netbook set up the way i wanted it, everything was working great. The notification popups were annoying me so i was trying to disable them. I used this string in a terminal: sudo mv /usr/ share /dbus-1/services/org.freedesktop.Notifications.service /usr/share/dbus1/services/org.freedesktop.Notifications. service.disabled
After rebooting i had nothing but a taskbar.No icons, no panels, nothing but wallpaper and the taskbar. I can't even figure out how to open up a terminal.Hopefully there is a way to load synaptics and reload the desktop somehow?

I'm making a Home Theatre OS, and I would like my XFCE ubuntu desktop to load up automatically without the use of GDM. This is because once remastered, the GDM cannot automatically log in until it's been set up to again. And the fact I removed all the GNOME icons which took up 50MB of space, so now the GDM interface is all glitchy xD
It basically involves removing GDM, logging in (the login and password are both 'media'), then having an automatic login command to run 'startx'. I've removed GDM on my test environment, and so far managed get in manually by logging in and typing startx. (On that note, do I even need a username and password? Can't I just use the password only for su?)

I have gnome which is the DE I always use, but today I wanted to try KDE so I did a 'yum install @kde-desktop', the installation went ok, so I rebooted just in case and logged on a KDE session, the animation for loading was displayed and when it was finishing it went back to the login window instead of loading the desktop. If I try the KDE live CD, on other computers it shows the desktop right away but on mine it sends me to the login window and the same, looks like its loading but it sends me back.
Gnome keeps working ok, I can even launch all KDE apps installed like Dolphin and stuff but can't run a KDE session, does KDE 4.X have a special hardware requirements?.

After upgrading from 10.10 to 11.04, my machine was freezing as the desktop was loading. The mouse pointer would move and some of the basic shortcut keys would work, but nothing on the screen was responsive.
I've got the NVIDIA 7300 LE video card, so i thought it was a conflict between that and UNITY (which I have ZERO interest in running), so I move over to a terminal login and this is what it looks like: [url] (click for pic - apparently, not everybody uses a 55" LCD as a monitor)
I can type like a regular terminal window, but obviously I can't read anything. I ran 'sudo apt-get remove unity' (and then 'sudo apt-get install gnome' when that didn't work) but the desktop still doesn't load and the terminal login tabs are still completely illegible.

I'm running Ubuntu 10.10 on an Acer Aspire 5530G. On a fresh install, the HDD is silent after logging in and the desktop is immediately ready for use. A few days and updates later, after every login, there's heavy HDD activity that lasts about 20/30 seconds and makes it almost impossible to perform any other task. The entire desktop is visible during said event.
Not a big issue, however it bothers me a little. I've observed this behavior since Ubuntu 9.10. Anyone else experiencing similar problem?

It always seems to me that Mac programs use far more resources compared to gnu/linux and windows. for example the mac version of Firefox is 27MBs while the windows version is only 12. Also system requirements for programs often require far more ram for mac than they do for linux of windows. Is this just because they are poorly written? obviously, the mac version of firefox is just as good as the windows version. but if it's heavier, and does the same stuff, then it's worse, right? This probably has something to do with stupid formatting stuff.

so I've scoured the web and I can't seem to find anyone else having this issue. The issue:
Whenever my box is heavily using the internet, it seems to just wimp out. It shuts off and reboots.
When it's happened:I first deduced the connection to the network connection when I was trying to set up the system. When I tried an upgrade after the first time I installed the system, it crashed, leaving me with broken packages and all kinds of mess. So I decided to start over, and since I then had the network set up, I used the install latest version feature in the installer. If failed again. I battled issue this a couple of times before I opted to do updates in chunks instead of all at once. Success. Then I tried to download an entire website. You see, I had bought the computer to use as a test server for work. I ran wget, I believe. After a lot of recursive downloading, it decided to take another unauthorized break.
Now, I've got a minecraft server running too. It's been working pretty nicely, until lately. I've got a cron job set up to backup the server files with dropbox. Bad, bad, bad. The computer started acting up again, shutting off and rebooting. I figured it was having a hard time uploading to dropbox while simultaneously serving up the game. I moved the cron job from hourly to daily, and haven't had issues all day. Great. Until late tonight. It did it again while we were playing. It's relentless. So I went through the whole process of assessing damage. Luckily no damage. Then I went ahead and ran the dropbox script that didn't get to run while I was performing diagnostics.

I installed CentOS with KDE and Gnome. the computer starts with a console instead of a window manager. When I try to start Gnome (using either startx or gdm), it freezes the whole computer. I can't even get to another command prompt using Control+Alt+F2, when I try to start Gnome.
After rebooting I tried starting KDE using the kdm command, but it prints out some error messages and logs me out of my session. (I've never seen a program force a log out of a session before! I thought that was strange.) I tried to record the errors by using the command "kdm > errors.log" and "kdm >> errors.log", but nothing is written to the errors.log file.
Also, under the (likely?) case that this problem is caused by the graphics card, I ran lspci and discovered that this computer contains this graphics card: VGA Compatible Controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)

I'm not entirely sure if this is where this goes, but problems occurred after messing around with desktop interface areas
Basically after logging in my screen turns black and then seems to fail out back to the log in screen. No error message, nothing. log in -> black screen -> log in
Ive tried to boot in fail safe gnome with exact same result.
Problems started after these two actions
1) was trying to get compiz to handle the desktop, so I disabled "show desktop" through Nautilus ( I re-enabled before logging off however)
2) was stupid and tired and accidentally uninstalled libglib2.0-0, libglib2.0-data, and several other packages through the software center interface. Ive re installed these through root access but I must be missing some files because it still fails to start
Because im not entirely sure what is causing the problem ( failure to render, or missing crucial packages) im not sure how I should go about trying to repair. Is there any to restore factory settings and programs without blitzing out current drivers and apps ?

This morning I noticed that there was an update to the kernel ready in the Update Manager, to version 2.6.35-25. I let Update Manager do its thing and I restarted my computer when it prompted me to.If I select 2.6.35-25-generic in Grub, Ubuntu boots just fine, all the way to the login screen. However, after entering my password, it looks like Gnome is going to load, but it never does. All I see is the default wallpaper and nothing else; the system locks up and does not respond to any input; and the fans start spinning at full-speed. My only option at this point is to do a hard shutdown. I have no problems if I select the kernel I was using previously: 2.6.35-24-generic

Recently I changes settings on Ubuntu Desktop and I choose gnome failsafe login, hence everything loads nice except when the user accounts is load it only appears the background and the terminal. Is there anyway to have the desktop back the way it was with the complete gui interface?

I had just upgraded when after the first reboot I noticed that the black Ubuntu screen (with the little red/white dots) is actually white and buggy. It's unreadable and looks trashed.
After the first login, the desktop wasn't able to load properly, leaving me with a blinking, unresponsive icons and no menubars.
The only way to use the desktop environment is to choose Ubuntu Classic (both with and without effects) and Ubuntu Safe Mode.
I do have nvidia drivers installed (173).

When I load a fresh install of Fedora 14 on my system that the desktop doesn't load completely? It goes as far as giving me the desktop with a background, the icons and status bar do not appear. I am able to right click and open a konsle terminal but only when I am in KDE (failsafe)
What is weird is initially I had no problem. But when I switched to a different monitor the desktop would not load correctly. I have reinstalled the OS since then and still have the same issue.

I am trying to get OpenSUSE 11.2 working. Everytime I install it, it installs with errors but when the user I setup auto logs in to the GNOME desktop, the desktop never loads. I can get into failsafe mode sometimes. I've replaced the harddrive and installed it again = same issue. I've redownloaded and burned a different DVD, verifying the checksum, and running the "check media" option = same issue. I've done a repair install = same issue. I've removed the added Ethernet and modem cards and reinstalled = same issue. I've deleted all partitions from previous install and reinstalled = same issue. Currently, I just defraged the HDD on a windows machine and am running the install once more (one a completely different machine) but what's going on here? I need 11.2 for Clonezilla SE (not 11.3)
