General :: Low Performance, GeForce GTS 250 Dark Knight?

Sep 25, 2010

I need someone to please point me in the right direction with this. I'm using a supposedly nice graphics card under Ubuntu 9.10, an Asus GeForce GTS 250 1GB Dark Knight, and I think I'm getting a poor performance out of it. I realized this when "backing up" some movies I have on DVD and took more than 30 min with k9copy for each DVD.

The CPU is a AMD Phenom II 955 X4 Quad Core 3.2Ghz Black Ed. 125W AM3. Which I think is powerful enough for not to be a bottleneck. Maybe there is nothing wrong with the graphics card and the bottleneck is somewhere else. I provably should benchmark my system to find out if I'm not taking advantage of my hardware. I've seen phoronix has a test suite. Any other recommendations?

Fedora :: 13 With Geforce 8400GS - Graphics Performance

Jun 16, 2010

I just did (another) fresh install of FC13. On the last install I attempted to install the nvidia proprietary drivers (tried every guide I could find). When I installed the proprietary drivers, I could no longer boot. It would hang at the end tri-color progress bar. I could ALT+F2 to get to tty2, and deleting the xorg.conf file and init 5 would get me back to the Gnome login. I continued trying other methods, getting such results as a black screen with no way to access tty. I tried using the rescue function from the DVD, but this time I couldn't fix the problem by deleting xorg.conf and executing init 5.

After failing in everything I tried for the proprietary driver, I decided I'd give the new nouveau a shot. Every time I fresh install FC13, the graphics performance is TERRIBLE. Moving a window around or scrolling in Firefox is painfully choppy and borders on unusable. I tried 'yum install mesa-dri-drivers-experimental' but after rebooting the performance was still beyond crappy.

I can get proprietary drivers working in Debian Lenny without breaking a sweat, but I prefer Fedora as a whole by far.

Ubuntu :: Got A Dark Font Color And Hard To Read On The Dark Background?

Aug 26, 2010

I'm using the shiki colors theme from the repos right now. "Shiki-Noble" to be specific. When typing something into Firefox's URL bar the internet addresses have got a dark font color and are hard to read on the dark background. Here's a screenshot: FF.jpg

I've had similar issues with other themes and Firefox's URL bar before.

Fedora :: Hardware - GeForce 4 MX440 Vs GeForce FX5200

Aug 28, 2010

Today I received as a gift a 5 years old Gateway 500X CPU which is apparently dead due to a faulty motherboard (I still have to troubleshoot it, of course).

Even in the cause I can fix it, odds are I'll prefer to make the aforementioned CPU a donor for my other machines, instead of resurrecting an old Pentium 4 (no HT) system.

Being this the case I checked the parts for possible transplants:

512MB DDR PC2700 memory module (useful right off the shelf for my main desktop system).
120GB Maxtor IDE hard drive (also useful, assuming it is in working order).
128MB AGP8X NVIDIA GeForce4 MX440 graphics card.

On this last part (the graphics card) I have my doubts as of where to use it. My main desktop system already has an NVIDIA card: FX5200, 128MB, which is newer. The thing is that I've been doing some homework comparing both the MX440 and the FX5200 and get mixed opinions: for one thing the FX5200 is the latest of the two with some advantages like support for a later DirectX (which for Linux is pointless) and other things, but the FX5200 is also reported to be technically inferior to the MX440.

In your opinion/experience which card is a better performer? Should I expect a performance gain if I were to replace the FX5200 with the MX440?

Ubuntu :: Ondemand Vs Performance - Increases The Clock Speed To Performance When The CPU Is Under Load

Jul 31, 2010

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.

General :: Wrong Display After Installing GeForce GT 335M

Oct 1, 2010

I bought a new laptop 2 months ago, with a GeForce GT 335M VGA and win 7 preinstalled. I installed in parallel Ubuntu 10.04 64 bit but face the following problem When I activate nvidia driver from the "hardware drivers" tab ( it gives me only one choice ,to install :version current" driver ), I get after restarting, my screed divided in 4 quadrants with something like a corridor in the middle ,each quadrant showing a tiny ubuntu log screen Only after uninstalling it or booting in graphics fail safe mode I get a normal screen again but then, google earth e.g runs slowly and complains that it works in open gl mode or something like that.

May be its only that the VGA card is new and there is not yet a proper driver for it? Or should I try some changes in some configuration file? I have tried the advices from [URL] but it didnt help . In win7, the card works fine but ....

General :: Efi And Bootloaders And Any Performance Advantage?

Apr 24, 2011

Modern systems seem to be EFI based, and while there's a specific version of lilo that works with it, i can't seem to find any mention of a efi varient of grub (edit - on modern debian derivative systems there's grub-efi. Most references to it seem to be about various bugs in/for it tho) . In general, how well is EFI supported on linux?In addition, apparently windows 7 uses EFI to enable faster boot - 12 seconds or so with some systems. While a properly tweaked linux system could probably come close, are there any enhancements to the linux booting procedure that take advantage of EFI?

General :: Can A Ramdrive Be Used To Speed Up Performance

Feb 1, 2011

I have recently upgraded to a M4A77TD motherboard and 8Gig of memory.I have a AMD Athlon(tm) II X4 645 Processor, and I cant say that I see much improvement over the one that died. I have noticed that the HDD light is constantly flashing so I wondered if I couldnt use some of the Ram to create a ramdrive to speed things up . So question ... what should I put on my ramdrive? My own thoughts were the var and usr directories. I would load the ramdrive at startup (which would slow down my startup) And Rsync back again on shutdown.Has anyone done this? Ive had a look through the forum but cant see anything ..but my search terms may not be all that good.

suse linux 11.1 64 bit
var=0.3G usr=5M lib=0.2G opt=0.6G sys=0.6G
As far as I can see swop is never used

Ubuntu :: Screen Fades To Dark?

and am coming from XP/Vista, loving it so far. But there is one problem I am having. After about 10-15 min of me not typing or moving the mouse, the screen dims and then goes to a screen where it asks for my password. This is getting very annoying while I am watching videos. How do I get it to stop doing this all together, I want to be able to leave my brother/friends on my computer and not have to come in every 10 min to type in my password

General :: Run Firefox Jailed Without Serious Performance Loss?

Feb 20, 2011

My Firefox configuration is tricky:

Firefox runs at separate restricted user account which cannot connect to main X server.

Firefox uses Xvfb (virtual "headless" X server) as X server.

x11vnc is running on that Xvfb.

On the main X server there is vncviewer running that connect to this x11vnc

On powerful laptop (Acer Extensa 5220) it seems to work more or less well, but on "Acer Aspire One" netbook it is slowish (on a background that firefox is loaded with lots of extensions).How to optimise this scheme? Requirements:

Browser cannot connect to main X server.

Browser should be in chroot jail (no "suid" scripts, readonly for many things)

Browser should have a lot of features (like in AutoPager, NoScript, WoT, AdBlockPlus)

General :: Video Card Performance Monitoring?

Jan 19, 2010

Is there a 'top' like command for monitoring the GPU and memory usage of a video card? I am most interested in Linux commands, but and OS would be interesting. I strongly suspect that for a group of my systems the video cards are being under-utilized (but I have no idea by how much) and would like to re-allocate funds to other bottle-necks. We are using higher end cards, so the price difference between cards is significant.

General :: Best Way To Test Graphics Card Performance?

I've recently been experimenting with glxgears, but found people saying this is not an ideal benchmark tool as there are many variants; for example resizing the window affects the FPS tremendously.

I'm interested in testing the difference between using the proprietary ATI driver and the open source driver and also the performance under various distributions.

What's the best software to benchmark graphics cards?

General :: Disk Performance Slower After Upgrade To 4GB RAM

Oct 19, 2010

I am running openSuse 11.2 (32-bit), my CPU only supports 32-bits. I have a hardware RAID device. My system has 4GB of RAM. When I configure my system to only use 3GB, 2GB, or even 1GB, using mem=1024M in grub, my RAID performance is much better then when letting my system use the default 4GB available.Can anyone explain to me why this is? Is there anything I can do, i.e. kernel configuration, that will help performance when running with all 4GB enabled?

General :: Hard Drive Partitioning Vs Performance

if I make more partitions rather than creating single one, will I get more data access performance? E.g Instead of keeping 1,5TB partition, create 5x300MB and keep different data in different partitions? Logically hard drive will spend less time on finding data in smaller partition then in bigger one, right? Is there any statistics for performance vs size?
