Ubuntu Multimedia :: Use 2nd GPU As The Main Display Device?
Mar 23, 2011
have a system that has a GTX285 and a PCI 8400GS. I'm running Ubuntu 9.10 I'm trying to get the system to use the 8400GS to run X windows and the GTX285 to use as the compute device. Everytime I start up my system with both cards it always uses the GTX285 as the display device. How do I configure it to use the 8400 instead? I've tried the nvidia settings program and I don't see how to do this. Do I need to change something in my xorg.conf ? I don't know much about editing this file.
I am trying to write a script to turn my HTPC off automatically and turn it back on again at a specified interval.
I've got the turn on off bit sorted using /sys/class/rtc/rtc0/wakealarm but I want the script to not turn the machine off if say something is downloading, I am currently watching something etc and i dont think I will have any trouble with that.
But what I would really like to be able to do is tell if my TV is currently on. I dont think anything x11 related would work here and this may not even be possible. Does Ubuntu "know" if it's display device is powered on or not? if so can I interrogate this somehow?
I really wanna use the OS. I wiped my laptop and installed it but I can't change my screen resolution (it's stuck at 1024 X 768 and my refresh rate is at 0 HZ) I tried installing a driver that was for both the i9xx and i8xx chipset family but it doesn't look like it helped anything. I want to be able to play World of Warcraft Wrath of The Lich King but when I try it the way the computer is now the the frame rate is really really slow. I also need to fix my audio because there's crackling that comes from the speakers often. I attached a screen shot of what I get when I enter the command: sudo lshw -c video Changing the resolution isn't the problem so much as the fact that I can't change the refresh rate from "0 HZ" to anything higher so that my game will play smoothly. I would also like to put compiz fushion on my laptop as well but I don't believe it will work unless I resolve this problem.
I have extended desktop working on my netbook (finally, by turning off compiz), but now Gnome prefers my netbook's main screen as the main display (with the panel and such) instead of my external monitor.How can I switch this? I don't see any setting for it in the Display dialog.
When I go to Main Menu>Places, nothing but Computer and Network works correctly. Choosing Main Menu>Places>Downloads, for instance, generates a little disk activity, but never displays a window with the contents of the Downloads directory. In an effort to fix the problem, I just upgraded from 10.4 to 1.10, but the same thing still happens. How do I get the Main Menu>Places icons to display the appropriate windows?
Usually the menu bar, and menus, are displayed within the applications main window. With a small screen this obviously wastes space so my idea is to reserve a location, small square space probably on a corner, on the screen that when clicked it will pop out the current selected applications menu, allow selection, and then disappear again. The application itself would look fullscreen, or if windowed will still not have a menu bar but access available via the "square."
Likewise instead of the usual task bar and "applications/places/system" menus (ala, ubuntu) a second square would be reserved which would pop-out and show the running tasks, followed by the menus, and allow selection, then disappear. Is this possible with GTK+ as it stands, as I'm guessing that by default everything must be contained within an applications main window?
Although having said that, gimp allows the tool windows to be external to the edited document, so perhaps it would be possible to make the menu bar into a toolbox? I guess the difficult problem would be how to make the currently selected applications "tool square" be on top when there could be multiple applications running. The "tool square" and "task/menu square" could be transparent (maybe just an outline) so that although always there they wouldn't hide any underlying windows/programs/etc.
Basically the idea is to get rid of wasted screen, in ubuntu (on gtk/gnome) a minimum of 5 "bars" is wasted screen real-estate:- 1, Running aplications: 2, Ubuntu's main menu bar: 3, Applications status bar: 4, Applications menu bar: 5, Applications description (min/max/close) bar. Take all the above and replace it with two clickable, potentially invisible, squares say where the default "hide all windows" and "deleted trashcan" icons currently reside.
The removal of the Firefox-Shiretoko Browser from the Main US Repository really wrecked me... I have no back buttons, no URL display, and all my bookmarks now have to be moved... (if I can figure out how to move them...) ooo, i miss my black-skin in Facebook...
Openshot appears to be dead, clicked the launcher nothing happened. Starting it in the terminal produced the following error messages: $ openshot ERROR 1 Failed to import 'from openshot import main' Error Message: cannot import name main

I hope this is not a totally ridiculous question. I use putty often to remotely connect to my laptop at home. I recently learned about the Linux framebuffer, and was curious if there was a tool like putty that would let me remotely connect to my laptop but use the /dev/fb0 device for forwarding graphics. Sort of like a vnc or X11 forwarding, but instead of using X, gdm, kdm etc. we use the framebuffer.
# mount -o loop /root/image.iso /media/cdrom in SLES10 (and SLES9), "mount" displays the name of the iso file: # mount ... /root/image.iso on /media/cdrom type iso9660 (rw,loop=/dev/loop0)
However, in SLES11, "mount" now displays the loop device rather than the filename:
# mount ... /dev/loop0 on /media/cdrom type iso9660 (rw)
This is somewhat less than useful. Is there any way to display the filename rather than the loop device?
I've got rhythmbox playing and to minimize the effect of the mic input being routed to the computer's main output, I wanted to set the main system volume to be fairly low and turn up the level in rhythmbox. Pulseaudio won't let me do that. If I change the computer's main volume, it changes rhythm box's volume, and vice versa. I don't think I saw that behavior before, no idea what changed.
Am I completely misunderstanding something? I thought the point of an audio server is so that the client applications could produce the signals in their own way and send them through the server. Why do they have to interfere with each other's settings? Is there some preference to make it stop doing that? I looked in pavucontrol, device chooser and manager, don't see anything.
Is there a way to have the VLC play list joined together with the main VLC screen? i.e. just like gnome-mplayer 0.9.8? I really don't like the separate windows setup with VLC, although VLC is still my number one video player.
How do I get netjack to automatically patch to the (physical) system outputs when it connects to jackd?
Currently I have to open qjackctl manually and route netjack every time I log in. Is there a terminal interface for jackd or a special switch arg on netjack so I may automate this from a script?
The problem I'm having is that when I plug in my headphones into my asus g60vx laptop I do not have sound, however if I unplug them I have sound through my laptop speakers. [URL]. Ubuntu 10.10
I'm working on a project to have our company logo image display on the screen during bootup. Our platform is an embedded Linux device running on a custom configured linux kernel 2.6.38.2. Our development distro is Ubuntu 10.04. I am currently trying to get fbsplash to work on our device with no luck so far.
I have to hold a presentation using a projector in a few days and I have to bring my own laptop, so I tried hooking up a second monitor to test if it works. As it turns out, the second monitor works fine, but then my main screen is messed up. I'm using Ubuntu 9.04 and I'm doing this on a HP Pavilion DV4000 laptop. My main screen shows just the bottom (cca) 400 pixels of the wallpaper, no bottom panel, no desktop icons. And I'm kind of scared to remove the second monitor now cause I don't know what I'll do if I don't get the main screen back.. Well, other than installing 9.10 beta that is..
I've been trying to install Handbrake (video converter) but its not in main repositories. So i went here and here to try and find a way to add the PPA. I got more or less the same error both times:
Code: https://launchpad.net/api/1.0/~stebbins/+archive/handbrake-snapshots: <urlopen error [Errno 8] _ssl.c:499: EOF occurred in violation of protocol> and this: Code: https://launchpad.net/api/1.0/~stebbins/+archive/handbrake-releases: <urlopen error [Errno 8] _ssl.c:499: EOF occurred in violation of protocol>
Recently our Son showed me Xscreensaver which he has running on his Debian Squeeze machine. Since I really like what you can do with it and since I use Squeeze as well, I figured that I'd try out the Xscreensaver on my system. Compiz is already working and I haven't had any 3D related problems yet. Anyway, so I install xscreensaver from the software center ... then I go to the main menu ... sure enough it's there alright. Then I place a checkmark in the box to activate/display that feature in the main menu ... but after a second or two the checkmark just vanishes. This happens over and over, even after rebooting.
I thought that a logged in user has full privileges over the items that appear in the main menu? Am I missing something? I don't know of any other (root) method to access the main menu with the apps ... Everything else reacts fine, just the folder for the xscreensaver can't be checked.
I have a headset microphone plugged into the built-in audio input. The output is plugged into an amplifier > speakers.
Pulseaudio is "helpfully" routing the microphone input signal to the speaker output. I do not want this. I go to pavucontrol and disable the "monitor of the internal audio analog stereo" -- and what I say into the microphone is still coming out of the speakers.
Google gives a lot of information about how to live-stream mic input over the Internet. And, I found this here (that's for karmic, I'm running lucid):

... but that's about how to ENABLE loopback. It says loopback should not be enabled by default, but I very clearly hear that something is doing the same thing as loopback.
(Of course, I need to hear sound from applications that are playing, and when I'm dictating text into NaturallySpeaking running under virtual box, I need sound input to go there -- so turning the mic all the way down to zero is not the solution.)
I'm fairly sure I remember hearing this behavior ever since installing Ubuntu, and I didn't do anything to turn it on. I can't imagine most users would prefer this behavior -- if it's the default behavior, why? It makes absolutely no sense to me. (Sorry. It's one of those piddly little configuration things that costs a couple of hours of web searching time, and after a while I just have to give up, but not before becoming much more frustrated than I should have to.)
So, to be clear, here's what I want:
- Applications playing audio should send sound to the main output.
- Applications receiving audio input should hear the microphone.
- Microphone sound should not EVER go to the main output unless I have explicitly launched an application making the connection. (The signal goes input -> output even when NO application is open - hence my consternation.)
What I am looking for is a dashboard type plugin for Rhythmbox which will show on the main screen ...then (because of the small size) I can use VNC on my Android Phone to see what is playing and to change songs etc.
I'm running 10.04 on a Fujitsu Siemens Amilo Pi 1505 laptop. Normally, when I plug my headphones in, all sound is diverted to them. I haven't found anything in sound preferences that changes this.(Under Sound Preferences, Output tab, there's a dropdown called Connector.It has options: "Analog Heaphones", "Analog Output" and "Analog Speakers" but they don't seem to make a difference.) I'd like to leave my headphones plugged in all day and setup my machine to play all sounds through my speakers (including Skype ringing), except Skype calls, which should play through my headphones. Skype has a feature to split the ringing and call sounds, i.e. play them on different devices, but the only option in each dropdown is "PulseAudio Server (local)".
My USB stick is this one: [URL] I can't get it to scan my frequencies. PC finds the stick (lsusb):
Code:
Bus 002 Device 005: ID 15a4:9016 Afatech Technologies, Inc. AF9015 DVB-T USB2.0 stick When I plug it in, dmesg shows this:
Code:

[code]....
But if the directory is created, then after the same command I have
Code:

I found on the internet a firmware for my USB HDTV DVB-T stick named "dvb-usb-af9015.fw" and copied it into /lib/firmware/ but I have not seen any difference with that.
I've been trying to find a way to watch videos from my main desktop computer on another computer I've plugged into an HDTV. I'm such a Linux newbie that I decided to give Mythbuntu a try. It was way to complicated for what I needed, and I'm sure that some more experienced people reading my first two sentences laughed to themselves at my naivety.
What I am trying to find is simple: browsing one computer's home folder from another computer, and playing the videos therein. If there's anything like Mythvideo that requires less than half of the skill requirements, I will telepathically send love to the person that informs me of it.
ireverter will not launch due to a java problem: "Could not find the main class: org.thestaticvoid.iriverter.ConverterUI"
In the past a solution was to add: "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni" before the java line in the script. This does not correct my problem.
how to get the display to the TV so I can watch movies. I have a Compaq Presario V5000 laptop, AMD Sempron processor, and an ATI Radeon Xpress 200M card. I have been using this successfully on Windows XP, but would prefer to get my feet wet more with Ubuntu.
The run timer in the lower left corner in the VLC window is off by a factor of 1.5553333...It displays 3 minutes elapsed, and 4:40 has elapsed on my stopwatch.edit:I just calculated the error for a 2 hour recording, and it worked out exactly - the clock is off by a factor of 1.5553333, for this captured format.
