Jun 4, 2011Basically I'm wondering if there is any way to lighten Gnome and Ubuntu I would like to keep Gnome if possible. I am a pretty experienced linux (or for you hardcore GNU fans GNU/Linux) user having used it for almost 4 years and I just built my Arch system but have found that alot of the functionality that I've come to love about ubuntu isn't in the default Gnome package but that Ubuntu's Gnome is heavily modified so I want to switch back but do to my lack of modern hardware I can't run Ubuntu as smoothly as I want.
Below is my current hardware.
Code:
Intel Pentium III 733mhz
512mb of ram
8gb Hard Drive
and a Dvd Drive
Nvidia Geforce 6600 265mb pci gpu
100 watt power supply
I am also a Developer so I know I can compile the Kernel my self and remove some not needed junk and optimize it. But I was wondering are there some Highly intensive processes that don't really need to be running? The only thing I would be using Ubuntu for is Web Browsing, Coding, Gimp, Text Processing and probably Music; thats really all I need I don't do much else besides that.
tl;dr:
Basically all I'm trying to do is lighten Ubuntu and Gnome without putting 3 days worth of work into it.

View 9 Replies View RelatedHardware :: Improve 3d Performance Of X800XL?
Jul 9, 2010I have got a Radeon X800XL built in my computer. I was able to play Quake 4 in high details once, so I guess my PC is quite fast. Anyway, I have trouble playing Anno 1503 and SuperTuxKart (sic!). While Anno 1503 is fairly unplayable, SuperTuxKart has got around 30 to 90 fps, depending on the situation. In my opinion, that's way to less.
My question is: How could I improve the 3d performance, to be able to play such legacy games as Anno 1503? Therefor I'll give you some information about my configuration and what I tried so far.
I run Ubuntu 10.04. That means, the driver provided by AMD/ATI (fglrx) does not work anymore. My Ubuntu is up to date.
I set the kind of graphics card and the graphics ram in the Registry of Wine. Disabling the compiz-fusion-effects does not improve the situation however.
I disabled KMS. That gave an amazing performance boost, but still not enough. I am still experiencing performance troubles like being unable to play Anno 1503, and some others.
I also created a Xorg.conf, trying to tweak some settings, but that does not improve the performance much. The config file is attached below.
How to improve or accelerate the 3d-performance. Maybe there is an beta-driver or some xorg-settings I did not find?

OpenSUSE :: How To Improve Graphics Performance In Xen Guest
May 10, 2011I was using centos for my business applications and now I am trying to work only with opensuse and install my other oprerating systems in it. I was always using vmware , but I decided to try another virtualization technologies other than vmware for testing , I searched the internet and found many other like virtualbox , kvm , xen. I concluded from my search that xen and kvm will be the faster type , I decided to test them, I choose xen, it is better than kvm. I installed opensuse 11.4 and installed xen hypervisor deployed two VMs windows xp and centos 4.8 , they are runing quite good but I have some questions:
1 : Isn't there anyway to improve graphics performance in xen guest , or change the video card memory or type ?
2 : Isn't there any way to copy and paste between the host and guest ?
3 : Isn't there any free application like vmware tools or virtualbox guest tools for xen ?
4 : I use these VMs to install some applications for my geophysics work which requires good graphic performance in the vm , also I don't them to be sluggish sometimes , which is better for that vmware or xen ?
Programming :: Will Multi-Threading Improve Performance?
May 18, 2011So I have built a program that takes a picture from two cameras every second and converts them both to jpeg format. The problem is that currently it takes ~2 seconds to convert a single raw photo to jpeg format, thus every second I add another raw photo (30 MB) to ram waiting to be converted to jpeg. So, theoretically the conversion to jpeg is running on a single core with hyperthreading, would I see better performance running the exact same process (a program pulling from a queue and converting to jpeg) running as a single process, or two concurrent processes? (both processes running on the same core, (so 1 thread on one clock cycle, the other on the other... (or one thread running on 1 core and the other on another core. What other steps would you take to improve the performance so there would no longer be a race condition?

Ubuntu :: 10.04 - How To Improve Performance And Fullscreen Video
May 6, 2010I have a Gateway Laptop which is dual-booting Windows XP SP3 32-bit and Ubuntu 10.04, also 32-bit. The 64-bit version, would not install on my computer, even though the computer has 64-bit capabilities. It doesn't bother me that I use the 32-bit version, but something it is now doing seems to be affecting the way things work on my laptop. The computer has 4GB of RAM in it, an AMD Turion 64 X2 processor, and an ATI Radeon X-series graphics card. The monitor has HDMI capabilities. On the Windows side, it handles full-screen programs and operates very quickly. On the Linux side, I can also run things quickly. However, most programs on the Linux side are much slower-running than they would be on the Windows side.
Something I notice when my laptop goes into fullscreen on the Linux side, is that the color quality goes way down. You can see that it is trying to run in apparently 256 colors, and each individual pixel is very visible. It does not do this on the Windows side. Also, programs that I run on this half of the computer are very laggy, slow, and inefficient. I know that my computer has the video and processing power to handle these programs with ease, but it isn't utilizing all of it. How can I make Ubuntu run at a higher speed overall, by taking advantage of all four gigs of RAM and this 2.4 GHz Turion processor to run everything like Windows does?

I noticed the cron job has the option "Input to command", where after many hours googling a can assume this is where you type input after the cron job has run (for example, a password?). I have tired putting the password needed for the job (the cron job is an ssh root@address) into this field however the output when running the cronjob is saying "permision denied" still.
Is there some sort of character I have to enter in this field, like

View 2 Replies View RelatedGeneral :: Page 2 - Scheduled Cron Job Stepped Working
Sep 8, 2011The back.sh script is being run as user basil, whcih means that when it comes to copying the backup file to the target location you do not have the correct permissions to access the contents of the directory (it is rwx by root only).So, what do we do? Hoping it is ONLY the directory permissions which are fouling things up we have a range of options which, in not particular order of 'good', include:
a) change ownership/permission on target directory.
b) have the back.sh script run by the root user
c) set up sudo to permit the file copy to be done by root
d) use setuid on the back.sh to have it run, effectively, as root
A lot of the answer will depend upon what else the Dropbox directory is for. If it's JUST for your backups for this then I'd be inclined to:
Code:
chown basil /root/Dropbox
chmod g+rwx /root/Dropbox
which will permit the basil user full access and thus allow the file operations being done and give root access via the group permissions (not that the root user really needs this).Also, I'd be inclined to:
Code:
chown basil /home/xxxx/moo3/bin/back.sh
chmod u=rwx,g=rx,o= /home/xxxx/moo3/bin/back.sh
which will make things 'look' better, it just reinforces the point that the script is run (and owned) by the basil user.

General :: Improve The HTML Formatting In Evolution Mail Client

Basically, I am receiving some emails that look lovely in Thunderbird but not in Evolution because the HTML rendering of Evolution isn't as advanced.Here is a screenshot of the difference: how to improve the HTML rendering of Evolution? e.g. a plugin, tip, code patch, etc. The closest I've got is to right-click the email, "Save As...", save as a html file, then open in Firefox. Not exactly streamline!What emails can't it display well? We use the subversion revision control system which is set up to send an email whenever someone commits via svnnotify all nicely coloured via the --handler HTML::ColorDiff -d parameter. When Evolution fails to use the colours, I find it very hard to read the raw diff.
