I am experiencing very high memory usage since upgrading, and it has gotten worse over the months since release. I noticed with all users logged out, I can go to terminal 1 and htop puts memory usage at 600MB for an idling, non logged in desktop. This wasn't the case on karmic, and my usage has not really changed. Upon logging in, it goes up to 800MB-1GB, on the desktop and idling. This has also been referenced at these places:

Also, nautilus takes at minimum ~200MB and upwards of ~600MB sometimes, and Ive purged thumbnails already. That is utterly ridiculous for a window manager. why Lucid has gotten so bloated, and how to trim it up? Will Maverick address these issues?
I am a newbie to Linux. I wanted to know how to explicitly manage memory for applications running on linux. For example, I want to create an application (using C) that has two separate physical address ranges associated with it. How do I assign explicitly those address ranges (the ranges are user defined) to the program?
I'm currently learning the u-boot bootloader for an ARM926EJ-S system. The flash memory of the board is only 4mb. My bootloader is consuming 3 sectors and is approximately 195kb. I am using dfu protocol to update the firmware of the device. Is there any possible way to know the memory usage of the dfu protocol when the upgrading begins? How much memory does it consume when it is triggered in the bootloader?
I am curious about other's opinions on their experience using the official OpenOffice from their main website, not the one Ubuntu ships with their distro. I was curious about upgrading OpenOffice 3.2.0, which is the latest that comes with Lucid, and found that if you do the following, you can have 3.2.1 on your system, which apparently is a bug fixed release:
Code:
To install OpenOffice 3.2.1 in Ubuntu Lucid:
- Download latest version ('OOo_3.2.1_Linux_x86_install-deb_en-US.tar.gz') from [URL] - Extract and you'll see a folder called 'OOO320_m18_native_packed-1_en-US.9502' - Remove the existing version of OpenOffice (3.2.0): - sudo apt-get remove openoffice*.*
[code]....
So, again, I am wondering about other's experiences doing this, as looking at it, it does look a little different, at least with how it puts itself in the Applications menu, and it seems to run much, much faster. In addition, when removing 'openoffice', it frees up 263mb, whereas the official OpenOffice installation adds barely 200mb. Might there be more the Ubuntu one installs?
Also, another way I've noticed that it might be possible to upgrade would be to install the Maverick repos temporarily and install Ubuntu's OpenOffice 3.2.1 in Lucid that way. Is that a wise alternative?
I'd like to install the 2.6.35 kernel while keeping Lucid (just not in the mood right now to get used to a new release). Can someone point me to a tutorial on how to go about this?
is it good to just upgrade Ubuntu 10.09 to 10.10 but not clean install?I've installed so many applications so far in Lucid and if I clean install it, I've been thinking of reinstall all the applications back is a tiring process.
After I upgrading from Karmic to Lucid, I haven't been able to update my version further and also running apt-get shows error... Can anyone tell me why this is happening?
after upgrading to lucid very often a shutdown is impossible if I try to nothing happens. I have to open a terminal and enter "sudo halt". If you just enter "halt" you get "need to be root".
When will an updated version of Empathy be available for Lucid? Or is there an easy way to install the Meerkat version?
I intend to continue using Lucid for a couple years, but the version of Empathy available in Lucid has some issues with logging chats -- there's no way to disable chats from being logged and there's no easy way to delete chat logs. The current version allows one to disable logging but it's not available in Lucid, only Meerkat.
I have problem upgrading my ubuntu 10.04 lucid to a newer release of Ubuntu. I have done updates regularly but nothing prompt regarding upgrading Ubuntu. as mentioned in Ubuntu website, updating must result in a notification of upgrading. I want to know if there is any way to do this manually?
Error during commit 'E:Internal Error, Could not perform immediate configuration (2) on mountall' Restoring original system state
Yeah...that's what I get every time I try to upgrade to lucid lynx.
NOTE: I haven't updated for quite some time. I may have gotten one or two updates for karmic but that was it. Just thought it might be important....
NOTE: Also not sure if this is important, but karmic installed and did some funny stuff to itself. My desktop no longer exists. It just isn't there. Also, when I try to turn of my computer it gets all kinds of errors and eventually I have to just pull the plug....something about a dev loop0 right after is says its deactivating swap...
I am going to upgrade from Lucid 32-bit to Lucid 64-bit, and I have some questions as to what I need to do. My system is a dual boot of XP and Lucid, but I only use XP rarely nowadays. I know I have to do a clean install, so here goes. Do I have to blow away my current install of Lucid? If the answer to (1) is yes, what about Grub? How do I get a list of my currently installed applications?
Currently Lucid is on one partition. I have a Clonezilla copy of the file system. Can I restore the /home directory from that copy once I have installed the 64-bit system? If I decide to make /home a separate partition, are there any good rules of thumb about how much space to allocate to the various partitions? Are there any other directories or files I should consider copying from the Clonezilla copy?
I dont know if this issue has already been solved, or if there are other threads dealing with it, but Im quite desperate with this bug that has been annoying me since I upgraded from 9.10 to 10.04.
Firs I thought it would be GEM related, but Im using a proprietary graphics card, so thats not the way to solve it. I experience the problems a memory leak provokes, mainly that, as time goes by with the laptop turned on, the system needs more resources to execute simple actions, and it freezes too many times. Plus IBUS will, suddenly, stop working (I still don't know if it is related or not), and, most of the times I log in, Notification Area 2.30.0 will load with errors.
I used to use server 64, and it handled memory well with Jaunty and Karmic but with Lucid the memory usage is always high and can't run virtual machines.
Why my 10.04 install runs out of memory when it has hardly had chance to load the kernel. The symptoms were that it sometimes will hang after the grub screen with a blinking cursor. My user space splash screen doesn't appear either, it was when I was trying to fix that that I spotted the problem:
from my dmesg file: Code: [5.778823] lowmem_reserve[]: 0 0 24846 24846 [5.778829] HighMem free:3204284kB min:512kB low:3852kB high:7196kB active_anon:192kB inactive_anon:256kB active_file:596kB inactive_file:2288kB unevictable:0kB isolated(anon):0kB isolated(file) :0kB present:3180408kB mlocked:0kB dirty:0kB writeback:0kB mapped:1240kB shmem:144kB slab_reclaimable:0kB slab_unreclaimable:0kB kernel_stack:0kB pagetables:356kB unstable:0kB bounce:0kB writeback_ tmp:0kB pages_scanned:0 all_unreclaimable? no ..... This is a few seconds after loading the kernel.

Ran 'do-release-upgrade -d'on my server running Hardy.No problems during the upgrade.Rebooted after the upgrade completed, and I was presented with the new plymouth screen. This sucks for servers.It sat there displaying the logo for ~5 minutes.Hit CTRL+ALT+F1 through F8 and didn't see anything on the virtual consoles.Finally figured out that I had to hit ESC on the plymouth screen to actually see what was going on.It said /dev/sdi1 had problems along with /dev/md0.It sat there forever with no fsck status and no HDD lights blinking.
SysRq+REISUB and tweaked the boot parameter to remove 'quiet splash' and appended 'S' for single-user mode.Got the attached screenshot.The box has been sitting like this for ~15 minutes.Not entirely sure what to report a bug against at the moment. Plus the somewhat-new requirement of running 'ubuntu-bug' is pretty retarded in this situation. (Yeah, I know I can add some string to the URL to get around it.Why is it such a pain in the *** to report a bug?)I'm going to do some more digging to try and find out what is dying during boot.The new boot process is a bit of a mystery to me still, so if anyone has pointers or any devs want more detailed information,
I just upgraded from Karmic to Lucid and my system will no longer boot. The upgrade completed without any error messages, but upon reboot, it hangs at the loading screen. I cannot start the system in recovery mode either. Same issue happens. To get to the command line, I've appended:
init=/bin/bash
to the kernel line in grub. I then remount so I have r/w access.
It appears to be an issue with udev. While the loading screen is "loading," udevd_work scrolls a bunch of stuff that's too fast for me to read (nor can I copy and paste it).
/var/log/udev isn't showing any recent errors, only messages from before the upgrade.
I decided to upgrade to Ubuntu 10.04 a few days ago. My internet then stopped working.I changed the security for my network to WEP (instead of WPA)Is there another way around this problem or can I just download another driver? I do not intend to stick with a WEP secured network.
I had a nicely working karmic 64bit/windows XP install, but the "upgrade" button to 10.04 has finally got the better of me. Now, when the PC boots up, the following failure occurs:Memory CheckPCI device listingVerifying DMI Pool Data ......error: no such device:e9eb88c2-67f2-47a7-bf9d-50b77b2d3480grub rescue>_Some more information.linux is on sdb1when I type "ls" I get: "(hd0) (hd1) (fd0)"however, I've not managed to get "ls (hd1,1)" or similar to do anything, the best I get is "error: no such partition".the command "find /boot/grub/grub.conf" results in the error "Unknown command 'find'"I've tried swapping the boot order in the bios from hd0 to hd1 but that has made no difference.There is no grub loader, no linux, no windows, no operating system of anykind, just the "grub rescue>" prompt.
I am planning to move to Lucid from Karmic now that I am out of university for the summer and have time. I have heard that there is a way to copy your home folder over to the next release and all of the data and program settings will remain intact. I have tried some research on the subject but everything I have found has been extremely confusing. I want to do a fresh install (as my updater has been failing time and time again and asking for partial upgrades etc). Instead of creating a new partition for the home folder, would it be possible to move it to an external drive and copy it back over (I have tried to copy it to the external but I get some errors even in sudo)?
I tried to upgrade my kubuntu 8.04 LTS to Ubuntu 10.04 LTS as given here. Actually I wanted to upgrade to kubuntu. The download completed successfully. However,while upgrading the power went off and left the computer in bad state. Now I see multiple two entries for both
in grub. Since I am not that familiar with ubuntu(in general linux), I would like When I tried to boot in first two of these I get the following error message and it remains in command-line mode.
However, the mount points are not having anything. It is like nothing got mounted. I would suspect there should be some way where I should be able to locate the downloaded upgrade stuff and apply it afresh again from start. Is this something possible?
I have just upgraded my OS from ubuntu 9.10 to 10.04.Now I'm facing problem of not having write permissions to USB drives (Pen drives).I have to use terminal with sudo to copy , move files and unmount media.
When this happens you have to open a terminal, get the process id for mysql-server-5 then kill that process. Like this: Code: ps -A then from the list of processes that it spits out look at the process id (the number at the beginning of the line) for mysql-server-5.
Now type Code: sudo kill -9 XXXXX where XXXXX is the process id for mysql-server, and enter your password. The upgrade process should now resume.
after upgrading to lucid lynx ubuntu doesn't boot with the new kernels 2.6.32-22-generic and 2.6.32-23-generic (also in recovery mode). But it's does boot with the previous 2.6.31-21-generic kernel. At the time i was hoping to wait it out, but a new kernel has come and the problem persisted. I've been trying to find a solution for this but somehow, amid lots of failed boot blank black screen threads, i didn't relate to any solution. The boot seems to go well until a pixelated logo appears (before the login screen), then goes to a blank black screen and there it stays stuck with no remedy. Looking into dmesg logs - albeit some differences between 2.6.31-21 and the newer 2.6.32-23 - the failed boot seems proper in both logs. In Xorg logs the differences are bigger but i cannot pinpoint a source for this problem.
If I try to open Cinelerra from the GUI, it does nothing. If I try from the terminal I get this:
Code: cinelerra: error while loading shared libraries: libfaad.so.0: cannot open shared object file: No such file or directory I've been looking around all over the place and can't find a way past this. I really want to get it going again, can anyone help?
I've checked in synaptic and I have libfaad2 2.7-4
I got an error during the upgrade but chose to let the upgrade complete. Now my Firefox won't lauch. I tried uninstalling and reinstalling it from the Terminal and got the following:Quote:
