Ubuntu Multimedia :: Nvidia Video Memory Misreported
Feb 24, 2011
I'm trying to increase my framerate on World of Warcraft, and I'm not sure if this will help but it should in theory. I'm not even sure if I'm right in my assumption that it's currently non-optimal. nvidia-settings reports the full 1024MB of onboard video memory from my 420GT, but lspci reports three separate figures which don't even add up to 256MB:
[Code]....
Now, I don't know which to trust, is all the video memory being detected or just the pittance that lspci reports? To my mind, more graphics memory means you can store more graphical code and data closer to the gpu resulting in faster framerates, right?

I have an old video card, Nvidia XFX 7800GT, which is now beginning to fail and I need to upgrade. I am not huge a gamer but I do play/buy games on regular basis. Right now I'm playing Eternal Lands on the Linux side. Looking to spend $100-$150 on a new card.I have a Core2Duo Wolfdale 3.0, with 2ghz ram and run Lucid 32bit. Also run windows Vista64Ultimate on dual boot (rarely).
I would love to buy a new ATI 5770 or 5830, ATI budget cards seem to be much better for the buck over budget Nvidia cards, but I'm concerned with ATI drivers and long term with Ubuntu.On the Nvidia side I'm considering the GTS 250. The only advantage I can find is lower power consumption with Nvidia and Ubuntu has always preferred Nvidia over ATI, as far as working drivers go.As Far as Ubuntu and Lucid is concerned, which way is best, ATI or Nvidia? Has anything changed with ATI support, that could make theor cards more compatible now and in the future?

I'm using my Ubuntu 10.04 as a server, headless or with HDMI receiver/TV setup. There is a lot's of topics how to make it work headless/VNS. I found the least trouble is to make a fake VGA from old VGA cable and 3 resistors. However, when I start my Ubuntu with Fake VGA it won't switch to HDMI when I turn my Receiver/HDMI on. If I restart X it is fastest way to pick the HDMI Video/7.1 Audio up. I can do it via VNC or ssh and going to do it with 'irexec' so my wife will be able to redetect the HDMI and run XBMC with one button click of the remote.The problem is restarting X kills all my GUI apps (KTorrent, ...). Is there a way to force the video driver to restart or redetect the screens?

I have a 64 bit computer with a 64 bit distribution of Ubuntu. The driver for the onboard video card wasn't supported beyond 8.04, so I didn't upgrade. Yesterday, I bought a NVIDIA GeForce 210 video card. I installed it and Ubuntu detected it and worked, but the resolution was limited to 640x480 (I think). I figured this would be corrected by updating, so I updated to 9.04. When I had to restart, the option to select which OS (Linux or Win) came up, I selected 9.04, and the ubuntu symbol came on. The status bar went to the end and the screen turned black, flickered 5 times, turned black and stopped progressing. The xorg.conf file is:
Section"Driver"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
Section"Monitor"
Identifier "Configured Monitor"
EndSection
[Code]...
I tried changing the driver from "vesa" to "nv" without any effect. Does anyone have any idea what I should do to get this to work?

currently using nvidia accelerated graphics driver (version 185) and a nvidia 8800gt. cpu is an intel c2d e6600, so it's quite a fast pc. video playback is extremely choppy to the point of being unwatchable. it affects all applications that i have tried, such as vlc, movie player and flash videos in mozilla firefox. videos on videos seem slow but playable, but when i try to watch them in full screen there's a drop to about 5fps. cpu usage reaches 100%. scrolling is also slow on large webpages. disabling compiz makes no visible difference.
before i installed nvidia's driver, videos played perfectly. videos play fine in windows xp. it seems as if nvidia's driver is using the cpu to 'process' videos, instead of the graphics card. other than that, ubuntu 9.10 is lightning fast... so what's going on here? i have resolved one issue, that is flash player's performance in firefox. followed instructions [here] and videos is now smooth in full screen. other videos, however, are still stuttering and spiking cpu usage. this must be a widespread issue, but the lack of information on the web shows otherwise.

I have 9.10 64 on a HP TX2020 laptop, with NVIDIA GeForce 6150. I can't get twin monitor to work. When I go into Nvidia X Server, it doesn't recognise the tv over s-video. According to a lot of the forums I've searched, there should be an option to enable xinerama, which there's not. I know I should study this more and I will, but getting simple things to work takes so long on this OS and I'd really just like to see a movie.

I have thrown together a frankenstein of spare parts to stream video onto my TV. The GPU is a NX6800GS (geforce 6800). I have used the restricted driver tool to intsal the recommended driver. The VGA output works fine. My problem is that when using the nvidia tool to set up my TV through S-Video on the graphics card, the TV is not detected. This puts me at a dead end, as every how to guide on this forum assumes the nvidia control panel can detect the TV. Can i force video to play over the S-Video port? Do i need some magical unicorn drivers for the card? Any help is appreciated (even a simple "this setup will never work").

I have finally got both video drivers working. Is it me or is the quality of the Intel drivers almost better than the nvidia? I will try something with hardware acceleration soon but the 2D (compiz etc) all works really well.

As of late I've been getting annoying video anomalies (see attachment) when using nvidias proprietary driver. I'm running ubuntu 11.04 64bit, my card is a 240 GTX and the nvidia driver version is 270.41.06.

I'm currently running a three-monitor setup, two of the monitors being connected to an NVIDIA card, and the third being connected to the motherboard's onboard ATI adapter. This works, and it actually works quite well, but after installing the nvidia-current drivers (using the GNOME dialog), I am unable to get any video acceleration going. The GLX module doesn't seem to want to load, and while I'm actually quite impressed with the video performance I'm getting with the open-source drivers, I'd really like to have the OpenGL capability, as it does make things look prettier.
Relevant configs and logs are below.
I should clarify - I don't care about the 3rd monitor on the ATI adapter; I'm only concerned with getting OpenGL working on the two on the NVIDIA - if that's possible, which it may not be...

Code:
xorg.conf:

I recently installed ubuntu 9.10 dual boot. All went well until I upgraded the video drivers for the nvidia chipset on my motherboard. If I leave Gnome to start with the single user i created i get a black screen and 'mode not supported ' message on the monitor. BUT if i drop to root and 'startx' all is well and i can adjust the various screen resolutions and they all work well.
At this point i created another user name to check, and that works fine also, but if i drop back to the original user i get no screen unless i select 800x600, although all the other resolutions work fine with root and the other user name. Im stumped as I presume there's only one xorg.conf file for all users.

I've tried to enable the drivers for a Nvidia 8400GS video card on Ubuntu 10.04. I've tried change desktop background > visual effects. It tells me Desktop effects can't be enabled. Sudo jockey-gtk looks and tells me no proprietary drivers are in use by my system. I've tried installing from Nvidia's site and that seems to go okay but doesn't seem to work. I have an internal video card that can't be turned off in BIOS )either ON or AUTO) that might be causing me problems.Lspci:Quote:

I have a Zotac IONITX-F-E motherboard (Intel Atom Dual Core 1.6 GHz + Nvidia ION) -based box with Ubuntu 10.04 64-bit installed. Do you or does someone you know have the same setup as I do? If so, do they have 1080p video playback working? If so, what driver are they using? I've tried following every guide I could find, but no luck so far. I have libvdpau1 and libvdpau-dev installed. I have the nvidia 195.36.24 driver installed (I used the nvidia installer). I have mplayer installed (which I compiled from source with --enable-vdpau).
I try to run mplayer with this command:
Code:
mplayer -vo vdpau -vc ffh264vdpau path/to/myfile.mkv
I get the following message in my terminal:
Code:
Error opening/initializing the selected video_out (-vo) device.
I have libvdpau-dev and libvdpau1 installed.
After Googling this problem, I found a post that suggested the following steps:
Code:
sudo add-apt-repository ppa:nvidia-vdpau
sudo apt-get update
sudo apt-get install nvidia-glx-195 nvidia-195-modaliases
It turns out that I had already added the nvidia-vdpau repository. However, despite that, I get:
Code:
E: Couldn't find package nvidia-glx-195
The same problem exists for the nvidia-195-modaliases package. Do these packages exist? Is there some other way to get them?

I have the most bizarre problem that started with 10.04. Up until 10.04 I had zero problems with my setup. I am convinced this has something to do with NVIDIA 7100GS and 10.04.
Here is the problem in a nutshell. I have my home desktop, which I upgraded to 10.04 from 9.10. Everything went just fine except when it booted up and I logged in, the video "shut off", the computer "hung" for about 10 seconds, then came back. I'm able to use it for about 10 seconds then the same thing happens. Video blanks, system hangs, comes back.
I've tried turning off compiz, no effect. I've tried nvidia-current along with other versions (including the one from the website) and they ALL have the same problem. I know it's not a hardware issue as I can boot the live CD just fine. I also upgraded to 10.04.1 and that worked fine until I installed the nvidia drivers. Here is what I dont understand either. I did a apt-get remove --purge nvidia* and the problem still existed after that.
Something is seriously wonky. I REALLY don't want to re-install the entire box. Now, here is something else that doesnt make sense. I have 10.04 installed on my work box with a Nvidia 9800 graphics card and I have no issues at all.

Having been using squeeze on my primary system for some time, I decided to install it on my media center PC. After doing a clean install I lost sound (another post) and my maximum video resolution dropped to 1280x1024. I was previously getting 1920x1080 (native) resolution under lenny on this box. So it's a mystery to me why I'm not getting that now. As you can see, the nvidia module is loaded:
# lsmod | grep nvidia
nvidia 9821382 0
i2c_core 12570 2 i2c_piix4,nvidia
PS--This was installed the "debian way" via module assistant.

I run Ubuntu 9.04 on with proprietary NVidia driver 180.44.When I change anything in the nvidia-settings, e.g. screen resolution, brightness, second screen etc, everything works fine - except for the fact that I can't play any video files in any player. Sound is there, players don't display any error messages, but the image is black. Flash video within browsers is fine, though.Things go back to normal with the new settings kept after restarting X. However, having to restart X and lose my desktop set up every time when I just want to connect my laptop to my office screen is highly inconvenient.Is this a bug or expected behaviour that I have to live with?

I have noticed that, using nvidia's latest drivers, HDMi output to my 32" LCD (1920x1080) and totem or vlc, the video on my LCD gets a bit "choppy" when the image changes faster.. some bars start appearing on the moving parts of the image.. like the system is having trouble rendering the video. This doesn't happen on my laptop screen even when both displays are running at the same time.
Also, this problem doesn't appear in windows 7, everything works perfectly there with one odd thing... the picture gets "choppy" on the laptop screen when I'm running both at the same time. It's not that noticeable, but I can tell the difference between windows and ubuntu in quality and it's annoying me

I recently upgraded to Lucid from Karmic and shortly before the release upgraded from a geforce 8400gs to my geforce GT240 and noticed no difference on Karmic. I read somewhere that the capability of video cards would be applied further with Lucid. Since installing Lucid I've noticed a severely reduced sharpness and severely increased contrast, changing the contrast in X server has no effect. My hardware driver is activated but not in use and no online fix I've attempted has been successful in resolving the issue. Is it possible to use a gt240 on lucid with no hassle and is there any way I can maximize my video cards capabilities?

I can't figure out how to install the nvidia drivers for my nvidia 8800 GT video card. I've followed some other posts and all the posts seemed either incomplete, or led me down a path of which eventually broke my installation, that I needed to reinstall the entire ubuntu system.Again, it may not have been broken, i just didnt know how to get back in to the gui version of ubuntu, the instructions took me to the console terminal
1.) I've installed the ubuntu 10.10 64bit for i386 in an oracle virtualBox..
2.) downloaded from nvidia.com "NVIDIA-Linux-x86_64-260.19.44.run"
3.) Stuck don't know what to do.

I dont know if this issue has already been solved, or if there are other threads dealing with it, but Im quite desperate with this bug that has been annoying me since I upgraded from 9.10 to 10.04.
Firs I thought it would be GEM related, but Im using a proprietary graphics card, so thats not the way to solve it. I experience the problems a memory leak provokes, mainly that, as time goes by with the laptop turned on, the system needs more resources to execute simple actions, and it freezes too many times. Plus IBUS will, suddenly, stop working (I still don't know if it is related or not), and, most of the times I log in, Notification Area 2.30.0 will load with errors.

I have have to write a video device driver, but rendering will happening in memory, not on a physical card. I already wrote a simple driver stripping out hardware piece code from an existent vodoo driver. I an install it, uninstall it but i dont know how to map it to a file /dev/mydevice_video
Is there a field in fb_info or fb_vscreenifo where the device name has to be passed before calling register_framebuffer.

I just got a Sony DCR-DVD108. It uses a mini dvd and a memory stick pro duo. It was a gift, and it's the first time through the rodeo for me using this set up. I can get the card recognized when I plug it in using a card reader. I want to record video, and that's where I run into problems. When I insert it, I get something saying that I have still photos, and Shotwell is the default photo software. That would be OK if I had still photos, but like I said, I'm going for video with this set up. I have VLC, but when I tell VLC to "open capture device" under "Media" it gives me a dialog box with (I think) Linux 2 as the capture method (this is going to get a little fuzzy as I have no idea what it's looking for here) and a couple of blanks that need filled in. I may be going about this bass-ackwards, in fact I probably am, but like I said, this is the first time I've messed with a memory stick pro duo. I guess since it's Sony they want me to go out and buy a Play Station to get this to work. I don't think I want to go there. I might be barking up the wrong forest with VLC, but Wikipedia says it will play it.
