Insane Tweaking for Speedfreaks (Geforce2 MX/MX 400)

Posted: Wed, 04/30/2008 - 20:18
Hello, I just installed 64studio on my desktop computer. Installed nvidia-glx-legacy-96xx, nvidia-kernel-common, nvidia-kernel-legacy-96xx-2.6.21-1-multimedia-486 and changed Driver "nv" to Driver "nvidia" in my /etc/X11/xorg.conf file. But I am still suspicious if nvidia driver is used properly. Can I find out this somehow? Thanks for help.

Hi mirami, Hope you're well, \#.....total.............used.......free Mem: 1004 used 422 free 581 Mem: 1004 used 278 free 726 This is another method to improve memory, security and boot up time. "WARNING".....Do Not Remove these, If you don't know what they are for. This is a "GUIDE" Laptops and Desktop computers require different services. Be careful here!...you can break your install...beyond repair... $ su \# cd /etc/init.d/ \# ls -a you will now see the services. \# update-rc.d -f (SERVICE-NAME) remove For example to stop anacron service you can type command as follows: \# update-rc.d -f anacron remove check these out first, double check (google) service-name to sure. http://fedoranews.org/mediawiki/index.php/Which_Services_Can_I_Disable%3F http://www.debuntu.org/how-to-manage-services-with-update-rc.d Cheers!

Hi Dave, I have been out for while.... thanks a lot for your help. I followed your suggestion and I have minus 150MB used memory now... very good. \# free Mem: 1004 278 726 I disable "fast writes" and remove bluetooth and wifi software which I will not need on my PC. Also I disable some services which I will not need there I was very careful because my low experience. I will continue carefully with this a little.

Hi mirami m> Probably yes , this is fresh install without any tweaking. I misread this as a new install today...sorry. While I check out these stats.... Check these out. go to Menu > Administration > Services > and disable any you dont use. This will improve memory usage and security. e.g. atd ssh festival bluetooth (make sure you don't use them). Software: $ dpkg --get-selections > software1 and again $ dpkg --get-selections > software2 This will create 2 files in your home directory software1 software2 These list the software installed, leave software1 alone. $ grep "cups" software2 $ grep "blue" software2 $ grep "bluetooth" software2 etc.,etc., only you know what is not needed. $ sudo apt-get remove --purge (not needed software) Watch very carefully for shared libs and others apt might try to remove. This method will also keep a .bash_history of the software you have removed. $ dpkg --get-selections > software2 again will update the file minus the software removed. back soon, checking out stats and browsing Geforce2 MX/MX 400 for memory hogging.

Hi mirami, My fault mirami I didn't explain that very well at all :( but the results still tells me a lot about you're ram... This is what I did: I opened a terminal and wrote down how much FREE ram I had with just the terminal open. Then I opened my browser and wrote down how much FREE ram I had with the terminal and browser open. I used a calculator and subtracted free2 (with browser) from free1 (just terminal). test A: tested twice. iceweasel [about:] is using (1)=13676 under 14MB. iceweasel [about:] is using (2)=13567 under 14MB again. Then repeated the same only this time with (3 tabs open). test C: iceweasel (3 tabs open) using (1)=49896 under 50MB * I am still using a small % of 1 GIG. * This is the real test. Java. Iceweasel (Firefox IE and Opera) when encountering any form of java will start to gobble up memory. The only way to release it is to close and restart it. *Try a page that uses java, see if you reach 100MB...* I'm thinking this is what is causing problems with you're browser... Cheers, dave

Hi mirami, The story about the graphics card was to let you see how hardware can hog you're computer without you realizing. The links we have been browsing repeats 'bugs' many times in the same sentence as nvidia-glx-legacy. I don't know which is the best card. I will help you find out. 64studio offers nvidia. So that's where we should start. A Gaming computer B Desktop computer C DAW: My main recording studio has no desktop background no screensavers no games no printer. All things not used or needed are removed, less to go wrong. It's used for music. Music has great healing powers. BenchMark Iceweasel test A: in a terminal: $ free mem total used FREE shared buffers cached open you're web browser (iceweasel). (home page is [about:]). $ free mem total used FREE shared buffers cached iceweasel [about:] is using (1)=13676 (2)=13256 (3)=13280 Tested three times all using the [about:]home page. close iceweasel test B: $ free mem total used FREE shared buffers cached open you're web browser (iceweasel). http://www.nvidia.com/page/home.html $ free mem total used FREE shared buffers cached iceweasel [nvidia.com]. is using (1)=39444 (2)=36724 (3)=36776 close iceweasel test C: $ free mem total used FREE shared buffers cached iceweasel (3 tabs open) [nvidia.com][64studio.com][distrowatch.com]. Is using (1)=49896 * I am still using a small % of 1 GIG. * Iceweasel (Firefox IE and Opera) when encountering any form of java will start to gobble up memory. The only way to release it is to close and restart it. Check out how much memory your web browser is using. Try a page that uses java, see if you reach 100MB... How many computers do you have? How long has you're current install of 64studio been on the computer? years, months, or weeks? Since the install have you made any Major upgrades/installs or changes? Does Wine have a registry? Does Wine use the linux swap or does it create some type of virtual memory of it's own? I will check out the last two, and the other links from previous posts. Also I will look at installing wine on my test pc. One poster in one of the links has upgraded Dapper to Edgy to Feisty. "wow" back to the snooker, cheers! Dave. (Edit-syntax-Dave)

Hi Dave, 1.Web browser Of course I was talking about iceweasel I meant "web browser" (any) sorry for confusing terminology. I've tried Wine because I've wanted to use some my favourite VST, but I am not Wine expert. As regards performance I think better is use native Linux plugins. 2.Graphic card You think I should consider to get another graphic card? If yes which one you suggest? My motherboard is ASUS P4C800/P4P800 with Intel 875/865 Chipset by install CD. BTW can find it out exactly from /proc somehow? 3.BenchMark project My Ardour BenchMark project is prepared.

Hi mirami, > my system froze again even I didn't watch any video had just opened several tabs "in internet explorer". If you had wrote "in iceweasel", I would have said, your web browser should not make a great difference with regard to swappiness. "In internet explorer". Are we are talking about Wine & internet explorer?. * With the ram you have, web browsers (any) will be using a tiny % of ram * I dont use wine so you will have to teach me about it. Does Wine use a large amount of System Resources? Take a step backwards. (earlier post). >add this line to the end of the file. reducing the size by 50% vm.swappiness=30 50% is a huge chunk. You have to get to know you're system. Take you're time. Use the BenchMark and "slowly" tweak until you find the sweet spot or powerband/torque range of the computer. > Don't know where is the problem... still graphic card? I have had my computers set with "low swappiness" for a couple of years. no problem. One of the Biggest improvement I made was to change to a FX 5200 nvidia card.(less than £50). One machine had a GeForce2 Pro (game card), (legacy-glx-drivers), and it used a massive amount of the system resources. I changed a £300 card for a £50 card and my audio/studio improved instantly. > Don't know where is the problem... still graphic card? Have you created a BenchMark project in Ardour yet? Import a large wav file into Ardour. Create 5 Audio tracks to begin with, Add the same wav file one after the other. One long track. BenchMark project. Or if you already have a large project, this will do fine. You can convert ogg files to wav in your terminal $ ls -l youroggfile.ogg $ oggdec youroggfile.ogg $ ls -l youroggfile.ogg youroggfile.wav When the .ogg file is converted to .wav, follow the instructions above to create Ardour BenchMark project. http://lam.fugal.net/ dave

graphics card performance: testing

  • skullnotions
  • 09/29/07
  • Fri, 05/02/2008 - 23:30
Hi mirami, graphics card performance: swappiness This is why it is working better. WINDOWS. Windows creates and uses a huge swap "virtual memory" system. You had paid £££s for ram only to see your computer use 10% of this expensive and powerfull ram, whilst all your data was written to virtual memory to be re-read for use. Reading the data twice does not work when recording/editing audio. So we reduced the virtual memory size or if we had enough disabled it completely. This made the computer use the ram we had bought and gave massive improvements in performance. The secret was to find the best swap size to suit the system. Reading the data twice is a no-brainer when we need performance. LINUX. On linux we are talking about swappiness, and most distros default vm.swappiness=60 If you have 512MB of ram you can improve performance a lot by setting the swappiness. Once you have set this open a Large audio/video project to see how it runs, Use this project as a BenchMark to keep an eye on performance. You're main gain should be better recordings in "Ardour" as you are now using your ram to perform tasks without reading the data twice. Raise the value of swappiness if you feel the need, use you're BenchMark project to fine tune the system. dave.

Getting more power to your Graphics Card and Computer. On linux we are talking about swappiness, and most distros default vm.swappiness=60 If you have 512MB of ram you can improve performance a lot by setting the swappiness. $ su (password) as root \# edit /etc/sysctl.conf (using you're fav editor) add this line to the end of the file. reducing the size by 50% vm.swappiness=30 Reboot: check it out. then try vm.swappiness=15 Reboot: 15 is a good setting for 512MB ram. If you have 1 gig or more of ram. try vm.swappiness=10 Reboot: It's like finding the powerband/torque range of you're engine, use the ram you've paid for. Still browsing links, and watching snooker.

Hi mirami, Option "NoLogo" "True" Did you ever see a logo??? with or without this option? The Logo shows at the place you mention, and if it's failing, this could explain what's causing the flicker. My GeForce Pro used to flicker like this sometimes, I used to put it down to refresh rates. > After logging everything seems to be ok despite freezing of all desktop which I experienced today during watching some video on youtube. Is today the first time this has ever happened? Flash and youtube can be a pain at the best of times. If you think this is happening because of recent changes to you xorg.conf cp your xorg.conf now..... as it is. Take a step back and copy your xorg.conf-backup to /etc/X11/xorg.conf Reboot and try the video again. If the freezing still happens. This shows that the freezing has nothing to with any recent changes. Option "RenderAccel" "true" Is not needed with new cards but it can work well for older cards. you have to experiment with it to see what's best for you're system. > "True"-"true": I used to use "true" when I first moved to Linux, on searches I started to see "True" more and more so I tried changing over, I never noticed any difference. again see what works for you. > EDID we are both in the dark on this one, but no doubt we will get there in the end. did you check out grep "word" README.txt? It's a great way to save hours trawling through a large file. $ grep "EDID" README.txt I'm off to check out your two links. I am Learning loads here. Thanks, dave

Hello Dave, Yes I should explain my "flicker issue" more in detail. I happens only before "log in" screen appears. It looks like graphic card has a problem to set-up. After logging everything seems to be ok despite freezing of all desktop which I experienced today during watching some video on youtube. I comment out Option "RenderAccel" "true" in my xorg.conf reboot, tried watch video again for test and it freeze again. BTW in xorg.conf "Option"-"option" and "True"-"true" it is the same or should I care about capitals? As regards configuring EDID manually I found that this should works Option "CustomEDID" "DFP-0:/etc/X11/edid.bin" But still I don't know where or how to get edid.bin https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.20/+bug/91292 I will continue in searching... edit: here is some way to get edid.bin ... not sure if it can works somehow on 64studio http://www.edwiget.name/content/view/144/26/ and here good info for nvidia options http://http.download.nvidia.com/XFree86/Linux-x86_64/1.0-9629/README/appendix-d.html mirami Asus M6Va,CPU 2GHz, RAM 2GB, 64studio 32bit 2.1 pre14

You're welcome mirami, When you're on the desktop, is everything fine? does the flickering continue? or is it just at the "log in" screen? googled: monitor flicker before "log in" screen and found this, http://en.wikipedia.org/wiki/Flicker_(screen) The first section shows we are on the right path. The last section "Health Effects" is the most important part of this page. If the flickering is only at the log in screen, setting the computer to log straight on to your user desktop might be an option. especially if you are the only user! It would help if you post your monitor make and a link to the manual. back to tweaking: Option "RenderAccel" "true" worked well with my old GeForce, if not just remove it again. Driver "nvidia" BusID "PCI:1:0:0" Option "NoLogo" "True" Option "RenderAccel" "true" > disabling of EDID can be solution or set-up manually. The word bug apears many times in the link. If you want to try disabling EDID or set it up yourself, I will help as much as I can. I have never tried, and more research is needed here.

Then: $ ls -l README.txt $ grep "EDID" README.txt $ grep "Refresh" README.txt $ grep "RefreshRate" README.txt $ grep "flicker" README.txt $ grep "xorg" README.txt $ grep "monitor" README.txt $ grep "Monitor" README.txt Try other "variations" and search the file, I will do the same here. dave

Thanks for your support I tried this: Driver "nvidia" BusID "PCI:1:0:0" Option "NoLogo" "True" But still flickers... I tried this : Driver "nvidia" BusID "PCI:1:0:0" Option "NoLogo" "True" option "NoDDC" "true" But after reboot I couldn't get X works so I removed this line. (Hope it should be there) I downloaded manual for my LCD and set the horizontal and vertical frequencies in xorg.conf But the same... I was googling "NVIDIA(GPU-0): Unable to read EDID for display device CRT-0" I think this means some problem in communication between monitor and graphic card. According to this thread http://www.nvnews.net/vbulletin/showthread.php?t=93623 maybe disabling of EDID can be solution or set-up manually. There is also some huge document from Nvidia ftp://download.nvidia.com/XFree86/Linux-x86/169.12/README/README.txt But I have to say I need some advice here. mirami Asus M6Va,CPU 2GHz, RAM 2GB, 64studio 32bit 2.1 pre14

You're welcome, glad its getting better. > But my monitor still flicker before "log in" screen. This could be caused by your Monitor. >(WW) (flicker) It could also be caused by the nvidia Logo. If it's not already there, add (Option "NoLogo" "True"). As below. Driver "nvidia" BusID "PCI:1:0:0" Option "NoLogo" "True" > (WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0 CRT-0 I think is refering to your monitor. Do you have a manual for the monitor with recommended refresh rates? Google the lines below. Before changing any monitor settings. google: NVIDIA(GPU-0): Unable to read EDID for display device CRT-0 google: Geforce2 MX/MX 400 option "NoDDC" "true" google: (you're monitor name) Refresh Rates > Should I try to change "BusID" to something like "PCI:1:1:0" or "PCI:0:1:1" ??? This refers to the graphics card being in the 1st slot. 64studio has always configured this 'fine' so leave this until we know more. I have never had to changed this on 64studio. I use (nvidia FX 5200) the flicker sounds to me like the monitor. Refresh Rates? The system might need some time to settle down. dave

Thanks a lot Dave

I was followed your suggestions and my graphic card seem to go much better now. Specially "fast writes" helps "SBA" is not supported on my model. But my monitor still flicker before "log in" screen. I have one unresolved warning in /var/log/Xorg.0.log : (WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0 I've found this on nvidia web sites http://www.nvidia.com/object/IO_32667.html NVIDIA chip name: GeForce2 MX/MX 400 Device PCI ID: 0x0110 And I have this in my xorg.conf: Section "Device" Identifier "nVidia Corporation NV11 [GeForce2 MX/MX 400]" Driver "nvidia" BusID "PCI:1:0:0" Should I try to change "BusID" to something like "PCI:1:1:0" or "PCI:0:1:1" ???

You can also check how your card is performing like this. read: /var/log/Xorg.0.log and try: $ grep "WW" /var/log/Xorg.0.log This will show a list of warnings look for errors: e.g. non-existent font paths, resolutions and comment out or delete wrong parameters $ su (password) \# cp /etc/X11/xorg.conf /etc/X11/xorg.conf-backup If you ever have problems and are dropped into a terminal \# ls -la /etc/X11/ \# cp /etc/X11/xorg.conf-backup /etc/X11/xorg.conf and reboot should take you back to your default xorg.conf TWEAKS: \# edit /etc/X11/xorg.conf (use your fav editor) $ grep "WW" /var/log/Xorg.0.log shows: (ww) The directory "/usr/X11R6/lib/X11/fonts/misc" does not exist comment out wrong parameter in xorg.conf e.g. comment out (#) \# FontPath "/usr/X11R6/lib/X11/fonts/misc" Reboot for changes to work. When you have rebooted repeat \# cp /etc/X11/xorg.conf /etc/X11/xorg.conf-backup1 \# cp /etc/X11/xorg.conf /etc/X11/xorg.conf-backup2 So you have the working xorg.conf to fall back on without having to start from scratch each time. It's best to do one tweak at a time, e.g. (fonts first). take your time, and read /var/log/Xorg.0.log well before you begin. Cheers Dave. (Edit-syntax-Dave)

Everything is like before installing... but I have a feeling that graphic performance is a little bit smaller than I've expect. So I would like to know if my graphic is running on vesa driver or nvidia driver. Here is part of output from terminal after dmesg command: vesafb: framebuffer at 0xe8000000, mapped to 0xf8880000, using 6144k, total 32768k vesafb: mode is 1024x768x16, linelength=2048, pages=0 vesafb: protected mode interface info at c000:c210 vesafb: pmi: set display start = c00cc255, set palette = c00cc2da vesafb: pmi: ports = b4c3 b503 ba03 c003 c103 c403 c503 c603 c703 c803 c903 cc03 ce03 cf03 d003 d103 d203 d303 d403 d503 da03 ff03 vesafb: scrolling: redraw vesafb: Truecolor: size=0:5:6:5, shift=0:11:5:0 mirami Asus M6Va,CPU 2GHz, RAM 2GB, 64studio 32bit 2.1 pre14

Did your system boot normally?

Can you see everything you need to see? If you changed the driver to nvidia, and it did not start you would have seen the warning message that X could not start... easy as that. Doing graphics adaptor intensive stuff should be much quicker now.
