Ubuntu :: VNC And Gnome-rdp - How To Improve The Performance
Sep 1, 2011
I am running a ubuntu desktop machine as a server and use VNC from my windows machine to login via a LAN to the ubuntu machine. The login session is very sluggish and frustrating. I installed gnome-rdp to see if it would be better but I don't know how it works or what to do and if there is something else I can do to improve the performance. I have 3 gig of ram and the server is a dual celeron machine
Basically 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.
I 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 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?
I have written a script as follows which is taking lot of time in executing/searching only 3500 records taken as input from one file in log file of 12 GB Approximately. Working of script is read the csv file as an input having 2 arguments which are transaction_id,mobile_number and search the log file having these two strings with one more static string that is "CustomCDRInterceptor",then format the searched data in prescribed format.
I'm trying to do a partition alignment on my main SSD to improve SSD performance and then install Ubuntu on the SSD. I can do the alignment with no problem but when I install ubuntu the alignment is erased. Is there a way to install ubuntu without getting rid of the alignment?
dns cache serThis is probably more of a network question but I figured some one who is a network expert might know. Currently my organization has DNS servers. But my questions is would setting up a cache server improve the performance any? When I first thought about it i thought probably not. But since it stores information in ram that made me think maybe it would improve network performance a little.
I 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 ?
I'm using mplayer and libcaca on Gentoo. My framebuffer (uvesafb) is running at 1920x1200 (I don't know how many characters that is) and mplayer has problems filling up the screen, so video and audio lose synchronization.
So 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?
I'm thinking of installing openSUSE-11.1 Gnome on a Fujitsu-Siemens Amilo 7400M laptop because the wireless in Gnome is much more user friendly than KDE3/KDE4 in openSUSE-11.1. The idea is to give this laptop to my 84-year old mother and things need to 'just work' for her (she currently has a desktop running openSUSE-11.1 KDE3 that uses a WIRED interface to the web).
I refuse to update this laptop to openSUSE-11.2 nor 11.3 (nor other recent distributions) because every kernel update after the 2.6.27 kernel has broken the Intel i855GM graphics drivers for that laptop. There are many bug reports and none have fixed the problem for this Fujitsu-Siemens implementation of the i855GM graphics.
Hence I am looking at Gnome.
I booted the laptop to a Gnome openSUSE-11.1 liveCD and wireless is easy and works great. But audio is very very VERY bad. It is incredibly user unfriendly and it does NOT work well. I assume that is because pulse audio in openSUSE-11.1 was very immature.
I note these updated packages in the openSUSE-11.1 update repository:
Code:
So my question is, did the updates to pulse audio (in the openSUSE-11.1 update repository) fix the pulse audio situation? Are there ANY helpful views on this?
Currently my wife is using this laptop with KDE-4.4.4 (and openSUSE-11.1) so I can't just install Gnome and play with it without taking the laptop away from her for a while (note the hard drive is too small for a dual boot of KDE/Gnome).
I have a very simple question concerning gnome-do. I have configured to search for folders and files, starting from my home directory and going deep up to 20 directories.
The program gives me a message that it is indexing too many files, I guess it is giving up? it basically do not find some of the files/folders I try. the version is 0.8.2 for ubuntu 9.10
I'm toying around with fluxbox and like it's speed and simplicity. However, the gnome-panel is great and I would like to use it in fluxbox. Specifically, I like its system monitor, typing break, gnubiff and clock (which world clock support). My question is: if I'm running the gnome-panel in fluxbox will this degrade performance, for example, since the gnome-panel needs to load all the gnome related libraries etc.? One of the main reasons I'm looking into fluxbox is for speed so I don't want to lose that just because of the panel.
I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.
On my local apache web server I had installed gnome desktop, because I wanted it to use as a TV. But when I installed the gnome desktop, my requests for web pages became terribly slow (4-5 seconds!). When I deinstalled the gnome desktop, the request where fast again. But I still want to watch TV on my server, so I wander if people know why the gnome desktop harms the performance of the server?
PS. with gnome desktop, ping was <1 ms, samba server worked like charm, wget localhost was <1 ms, but for some reason, when tried to get a webpage from my webserver to a remote machine, it took seriously 4-5 seconds to load a page.
I installed bootchart and had my boot times analysed. Unfortunately, I can't make head or tail of the resulting PNG file. Could someone take a look at and tell me what I should do to decrease boot time?
I've got Ubuntu 9.10 running on an old thinkpad with an 800 mhz cpu. It's running wifi through a g rated card and a g rated router. The internet is very slow. I'm thinking of upgrading to an n rated card and router. Or, is the system just too old and nothing is going to help with internet speeds?
I have Ubuntu 10.04 installed and although I had some problems initially, everything works fine now. I'm just bragging about that. I do have some strange "issues" with my boot. I know that Ubuntu is supposed to boot with only plymouth visible, but before I see plymouth I have a fairly long period of time when I see nothing but a console cursor (a.k.a. caret) blinking. I'm no expert in reading bootchart charts, so I'm attaching it for some feedback. I have no idea how and what to optimize.
My boot is ~40 secs as noted on the bootchart, but it would be nice to cut some fat if possible. Also, my StartUp-Manager is displaying some veeery long boot options. It doesn't look nice. I guess he's reading /boot/grub/grub.cfg but I don't think I'm supposed to see all that. my boot and shutdown screens are very low res and very ugly, often flickering on updates. I have 10.04 setup at work as a web test platform on a very old/crappy PC (Intel GFX) and bootsplash looks much nicer than on my home laptop.
The hardware devices drivers list three different types of drivers onboard including what appears to be the latest one with accelerated graphics capability. When I try to improve the visual effects to 'extra' it keeps telling me there's an error. I've tried improving the effects with all three but still getting the error.
I have a old Pentium III box with equally old monitor (It says LG Sutdioworks 45v).I have installed Ubuntu 10.04 LTS.I have found it difficult to setup my screen resolution. It shows by default 800x600.After some tweaking I can stretch upto 832x624.I have seen resolution up to 1024x768 in windows on the same box and same monitor.How can I improve the resolution?I have searched and found out that i need a xorg.conf setup as Ubuntu cant identify my monitor properly.I also installed ddcprobe, read-edid.However I have met with limited success.
So I've been using Ubuntu on a Toshiba L645d, and after a few hiccups with the sound and wireless, it's finally working well now. However, the battery is still a bit less when compared to Windows 7 (2:00 vs 2:35, but it came with optimizations on W7 so that might be the reason. A comparison of power used: 25w of power on Ubuntu vs 17.5 on W7.
I've some videos with poor quality.It has pixelation and such problems.Can somebody suggest me some filters to be used with avidemux for correcting the pixelation and maybe deblocking it
I managed to install a second hand 10Gb HDD on my old P4. I want to see how I can use this extra disk to speed up Ubuntu 10.04 if possible.
I installed my swap onto this second drive but since I never use swap I can't see any real improvement. Next, I'm considering the creation of a new partition on that disk that would handle /tmp. Could that improve access times?
Finally, what other tricks could I use with this 2nd HDD to speed things up?
I've been studying air crack so that i can learn ways to improve my home wireless network and using air crack on ubuntu isn't as easy as i thought it would be.
after a recent foray into Ubuntu. Every day is a school day at the moment, so please be gentle! I recently obtained an old IBM Thinkpad T41 which I've made dual boot Windows XP and Ubuntu (windows was my backup option - it's installed but with none of the drivers; thankfully I've not yet hit a problem Ubuntu can't handle!) and which is connected up to the TV in our lounge. I have installed XBMC on it, and we're currently enjoying having access to all sorts of multi-media and iPlayer in the lounge. The thinkpad connects to our home network wirelessly, using the Thinkpad's built in wireless hardware - providing a whopping 11Mbps connection. Our media is all stored on NAS on the network, and I thought that even full 54Mbps wireless would not be fast enough to stream videos smoothly onto another machine.
However we have two windows laptops (one windows 7, one windows xp) which have 54Mbps connections and they can stream the videos smoothly from the NAS, so clearly I was wrong (wer'e not talking High def or blue ray rips here or anything). So my first question. Does anyone have an recommendations of a 54Mbps wireless card (PCMCIA preferably) that is compatible with both Ubuntu and the Thinkpad so that I can improve it's connection speed to the network? I have a "Max Value" branded card in the windows xp laptop (bought cheaply from Amazon) that I tried to but failed miserably to get working in the Thinkpad with Ubuntu last night. All hints and tips welcome....
Second question: Improving video playback on the thinkpad. Some of the videos were a bit choppy, which I thought was just to do with video quality. However having been playing them on the windows xp laptop - Sony Vaio PCG-FR215S, so similar in age and processor speed to the thinkpad - they play absolutely perfectly. So what are my options for improving the video playback on the Thinkpad running Ubuntu? - Upgrade memory to 1GB from 512MB? Will this make much difference? The sony has been upgraded to 1GB, which is why I ask the question. Do I have any options on the dedicated graphics processing hardware front? I'm guessing they are severely restricted as it's a laptop, but thought I'd ask as obviously I'd only be interested in something that is supported by Ubuntu.
Nvidia acceleration is enabled in Ubuntu, and in XBMC. The playback quality in XBMC is comparable with using VLC so I don't think there is anything XBMC specific to be concerned with at the moment.
Is it possible to improve Wine with a Windows install disk? I know if copy DLLs from a Windows computer, it makes some games work that don't work. Is there any way of doing this right from the install CD, without installing Windows on a computer first?
on OpenSuse 11.3 installed first KDE Desktop but my desktop Pentium 4 2.2Ghz is really slow... with XFCE work perfectly but XTerm is very poor. Cut and Paste text selection don't wok, like Mouse selection and font.
