I've been having some problems with Lucid; all my applications seem to be hogging memory like no tomorrow. Within about 15 minutes from booting the system, processes like Google Chrome, Nautilus, Python, Pidgin all start to take seemingly too large amounts of memory.
Chrome is the worst one, easily shooting over 200-300MB of my 2GB's of RAM. I would have reported this as a bug in Chrome itself, but my other applications seem to share the problem to some extent. Also: My colleague has identical hardware and identical versions of Ubuntu / Chrome, while he has no memory problems whatsoever.Currently I am running Chrome, Geany, Pidgin, Thunderbird and FileZilla. For this and itself, Ubuntu now consumes 1.8GB of RAM (that's including 500MB cached).
There are quite a few threads in this forum on how to convert a DJVU file into a PDF (among which this thread the instruction of which I followed.) I converted a DJVU file by printing it to a PS file from the Document Viewer. Then I printed again the PS to file into a PDF from that same application. The second phase took more than 24 hours and resulted in a scanned PDF of less than 500 pages with a size of 315 MB! I have many books of more pages which come down to 1 MB only. What happened in the process to make it so damn slow and so inefficient? Is there a good alternative (not ps2pdf because it provides the same result)?

What happens is, after the splash screen, both screens goes black and unresponsive. Tried killing X and alt + ctrl + f1 etc. I can probably fix this myself if I could access the terminal but, the other day I had to be stylish and remove everything from my grub boot besides Windows 7 and the default Ubuntu so I can't boot into root terminal. So, how would I gain access to a console before X starts?

The laptop I regularly use is out of use after having tried to upgrade from ext3 to ext4, following the instructions that can be found at namely, Step 2: Upgrading to Ext4Well, the first step was done without problems, but when I reached "Mount your filesystem", the problems started:When typingsudo mount -t ext4 /dev/XXXX /mntwhat appears is:UNEXPECTED INCONSISTENCY; RUN fsck MANUALLYStupid me, I did nothin but jump to the next step:gksu gedit /mnt/etc/fstabWhere I only got a fully white screen with no written text at all, instead of the menu that should have appeared, as can be seen on that webpage.
However, after running Gparted again, it showed the extension as EXT4, not EXT3, so I thought the system had automatically upgraded. Then I proceeded to boot the system, and this is where the massive failure appearedAfter seeing the Ubuntu logo for a while, the system directs me to a blank screen with the message:Mount of filesystem failed.dc5123-ec01-4438-8bd6-cb85bb080f87A maintenance shell will now be started.CONTROL-D will terminate this shell and re-try.root@hihihi-laptop:#So I type CTRL-D:

View 9 Replies View RelatedI have been using Wheezy for two years, and everything was OK, so I decided to upgrade to Jessie. In fact i decided to perform a clean install of jessie, so I formatted the partition where Wheezy was installed, and the /boot partition, and I installed jessie in those partitions.
As I had done with Wheezy, I installed jessie in an encrypted LVM, and the installation was ok (well, almost everything was OK, because grub and plymouth were not working, but I will open another topic about it).
First thing I did after installing Jessie was editting sources.list in order to download a few programs (plymouth, firmware linux non free, libdvdcss2, gufw, menulibre). Moreover, I downloaded a few progrmas from the Debian install DVD (flashplugin, VLC, chromium, clamav). i did not perform a dist upgrade because i was not at home, and where I was I did not have a Wifi connection (so I was using my mobile connecion -USB ethernet with an android phone-. BTW I had just performed a hard reset I had not installed any apps after that, so that mobile phone was "clean").
After that, I created a desktop user account, and I rebooted the laptop . When i rebooted, I started to tweak my user account: I edited dconf, and the gnome shell theme; and I started my mobile connection to download three extensions for gnome shell (window list, simple dock and activities configurator. I had used those extensions with Wheezy, and I had never had any problems). Ten minutes after I started the mentioned mobile connection, I reveived a SMS as I had used over 300 MB. Gnome monitor showed that I have downloaded 300 MB, and the android native data usage app showed the same. I did not download any video or music neither watch any videos on youtube, dailymotion..., I did not visit any suspicious web
I had a look at the apt logs and I din not find anything significant (I was using a no sudo user account, so i was not able to perform a dist.upgrade), I had a look at the download, video, music, picture folders and i din not find anything. I tried to check the iceweasel cache folder, but there were so many subfolders I could not check everything.
After installing Opensuse 11.3 i get massive graphical errors after reboot. Those errors directly start after the first resolution change after grub. So i used nomodeset from now on and installed the drivers from nvidia.

I have a program that is very heavily hitting the file system, reading and writing randomly to a set of working files. The files total several gigabytes in size, but I can spare the RAM to keep them all mostly in memory. The machines this program runs on are typically Ubuntu Linux boxes.
Is there a way to configure the file system to have a very very large cache, and even to cache writes so they hit the disk later? I understand the issues with power loss or such, and am prepared to accept that. Crashing aside, in normal operation the writes should eventually reach the disk!Or is there a way to create a RAM disk that writes-through to real disk?
Sometimes I need to copy a huge directory to another directory (local filesystem), and usually I will use the "cp" or "rsync" commands. These commands are good, but depending on the size of the data being copied, the copy is painfully slow. I realize we are limited because of the hardware we have with it's limitations, ie, I/O speed, and the filesystem (which is usually ext3). Are there any other utilities that maybe not well known, but can handle copying large amounts of data? (mostly in the TB range)
View 2 Replies View RelatedI recently tried out recordMyDesktop (not the GTK+ frontend, just the CLI program, I wanted to Keep It Simple this time ), and found that the videos it records/encodes show massive motion-smearing artifacts when played back. This is without the "--on-the-fly-encoding" option; with it, the video looks fine (i.e. has no artifacts other than the typical ones found in any compressed video), but it plays back too quickly (the time-step between frames is too high, thus making everything go too fast when the video is played back, even though the frame rate is low). Here's a screenshot of the video playing, showing what the artifacts look like (they're nasty!).
I've searched Google and LQ about this problem to no avail: either there were no relevant results, or it was just a post on a different forum asking basically the same question, but with no answer. So apparently this problem is either really rare, or it's something specific to my configuration, and mine alone (highly unlikely).
System specs:
CPU: Intel� Core� i5 430M @ 2.27 GHz
GPU: NVIDIA GeForce� 310M w/ 512 MiB VRAM
RAM: 4 GiB
Command used to record:
Code:
recordmydesktop --fps 30 --no-sound --no-frame --overwrite -o /home/mrcode/Videos/capture.ogv
I've tried different options, such as --quick-subsampling, as well as tweaking the video quality and bitrate settings (--v_quality and --v_bitrate), all of which did nothing to change/get rid of the artifacts.
If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.
How to install java and firefox java plugin on Ubuntu 10.10?
View 2 Replies View RelatedI try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.
Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object
That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.
