• Will Apple abandon OpenCL?

  - by John

  I am developing OpenCL applications, amongst others for MacOS. The new Macbook pro 13 inch comes with an Intel HD Graphics 3000 card so it seams reasonable to assume all their mainstream computers like Macbook and Mac mini will also come out with this Intel graphics card soon. OpenCL is not available for Intel graphics cards. Intel having a terrible reputation in developing graphics drivers and Apple knowing this makes me wonder Apple is abandoning OpenCL already again. Especially considering OpenCL should run anywhere, not only on high end systems. Developing applications only for the high end Macs with dedicated graphics hardware or for previous generation hardware with the Geforce 320M would not be a feasible option for me. Does anybody have any thoughts on this?

• After update, audio won't play throw hdmi cable

  - by ckhenderson

  Yesterday (June 7th) I faithfully updated a bunch of stuff through update manager (though I'm not sure what since I never read what I updated any more because I'm a bad person). Afterward, I discovered that I could no longer play audio through my tv via HDMI. The sound settings menu seems to have completely changed and the shell script that I wrote a week ago (with much pain and effort as I had never before written a shell script) to toggle between my laptop speakers and the HDMI cable output no longer works. When I type in pactl set-card-profile 0 output:hdmi-surround in the command line I get Failure: No such entity Presumably this means something with Pulse Audio changed but, while I'm learning a lot about the inner workings of Ubuntu/Linux, I'm not an expert and would love some help. EDIT: So I noticed that pacmd set-card-profile 0 output:hdmi-stereo seems to get everything working. Still, shouldn't there be a way to do this through the GUI as well?

• 5.1 surround sound for 12.04

  - by iwhorl

  I am very new to Ubuntu and linux as I have used windows only until yesterday. I am attempting to send my audio signal to my pioneer reciever using a single digital optical cable which is plugged into my M2N Sli Deluxe motherboard. I am sending video with a Geforce 8600gt video card through HDMI. That card does not support audio through HDMI. The only thing I have got to work so far is my left channel speaker acts as a stereo left and my sub woofer is trying to act as a stereo right. I was able to achieve this through altering the alsamixer settings. Can anyone point me in the right direction on this?

• Simpler Times

  - by Simon Moon

  Does anyone else out there long for the simpler days where you needed to move a jumper in the jumper block to set your modem card to use IRQ7 so it would not conflict with the interrupts used by other boards in your PC and your modem card came with a 78 page manual telling you everything you would need to know to write your own driver for the board including a full schematic along with the board layout showing every chip, capacitor, and resistor?  Ahhhhh, the simplicity!I am wrestling with UserPnp issues for a USB software licensing dongle that is needed by some third party software in one of our production applications. Of course, every machine in production is virtual, so it could be anything in the chain of the software application library to the device driver running on the VM to the configuration of the simulated USB port to the implementation of the USB connection and transport in the virtual host to the physical electrical connections in the USB port on the hypervisor.If only there were the virtual analog to a set of needle-nose pliers to move a virtual jumper.Come to think of it, I always used to drop those damn things such that they would land in an irretrievable position under the motherboard anyway.

• How can I use two video cards to power three screens?

  - by notatoad

  I have two Radeon 6450 graphics cards in my computer, with three screens. Only the screens plugged into the first graphics card are recognized and configurable in the displays setting panel. How can I use the displays plugged into my second graphics card? Both cards are present in lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc NI Caicos [AMD RADEON HD 6450] 01:00.1 Audio device: ATI Technologies Inc NI Caicos HDMI Audio [AMD RADEON HD 6450] 02:00.0 VGA compatible controller: ATI Technologies Inc NI Caicos [AMD RADEON HD 6450] 02:00.1 Audio device: ATI Technologies Inc NI Caicos HDMI Audio [AMD RADEON HD 6450] I'm using the open source driver instead of the proprietary driver because the proprietary driver won't output 1440x2560.

• Play videos with libwebkit in Ubuntu 11.10 server

  - by Luis Fagundes

  I'm using libwebkit (with python-webkit) to render a page that plays a video. This application works fine in a Ubuntu 11.04 Desktop, Nvidia card and lots of libraries and software installed, but in a fresh Ubuntu 11.10 Server with intel 82945G/GZ card the video does not play. I guess either some codec package is missing or it's a driver problem. What could be missing for this to play? I'm trying with this video: http://video.eustasy.co.uk/480/ EDIT: doesn't look like a driver problem. With chromium I can play the video, but with libwebkit + python-webkit the video just shows the first frame and doesn't play. Any hints on what package could be missing? SOLVED: apparently it had to do with lack of audio. While chrome would play the video with no sound, libwebkit wouldn't start video. Adding user to audio and video groups solved the problem.

• Ubuntu 11.10 UI changed suddenly?

  - by VeeKay

  10 64 bit on a Dell laptop that has 6GB RAM and 1GB graphic card. All of a sudden there were some sudden changes in UI which I am unable to understand why. The unity panel was initially glassy and transparent, now it looks all black in its background. Likewise the alt+tab graphics was working well until it got changed suddenly and now shows icons on pure white background. I've not tried to install any themes and I've not tried to tweak anything. Why did this UI changes occur? Could it be that it is unable to detect the graphic card or something? How can I fix this and how can I get back the original desktop back? Please help..

• Switching my legacy desktop back to Windows XP from Windows 7

  - by Kevin Shyr

  I was happy with Windows 7 at the beginning, until I started to add in the peripherals.  Windows 7 was never able to recognize any of my PCI video card (I know, I know, we should be in the DVI age). Anyway, I went through another 4 days of trouble setting my computer up with dual monitor in XP (also did a bunch of other things like getting rid of my sound card and taking the computer off RAID. Kind of feel stupid to put the computer on RAID in the first place because now I can have 2 drives: double the page files program seems to run faster Microsoft Sync toy 2.1 takes care of my backup needs (Thank god they solved the network drive issue) As of last night, the system is running beautifully.  I still have a laptop with Windows 7, but even that is in dual boot mode.

• ubuntu 12.10 graphic does not works correctly

  - by Amin

  I have installed Ubuntu 12.10 but my graphic does not works correctly. I used this command to installation: sudo apt-get install fglrx fglrx-amdcccle fglrx-dev But after the restarting my system, the side panel and upper one does not appear any more! I guessed it maybe that I used some incompatible packages so I removed the graphic card driver by this command: sudo apt-get purge fglrx fglrx-amdcccle fglrx-dev and tried it from graphical way from system setting > Software Sources > Aditional drivers and choosed the second option then applied change. But the resault waas such as before way!! I belive it is because of the Ubuntu does not know my graphic card. I am using VAIO VPCEA2TGX (N/A) and my graphic cart version is Mobility Radeon HD 5400 Series if it is matter. So now what is the exact problem and what I have to solve this?

• GeForce8800 ultra

  - by Gunnar

  I have been running Ubuntu 10.04 with GeForce 8800 Ultra graphics card without any problems for many months until a few days ago, after some updates, everything stopped working. Can't use Stellarium (my favorite program) and everything (even the mousecusor) stops responding for a long time. Takes ages to load the desktop and everything is just "f..." B.t.w. I have a dual boot and WinXP is not having this problem with the 8800 card. So, elementary... What's going on between Ubuntu and Nvidia? Best regards Gunnar

• Optimus Bumblebee Performance

  - by Chance

  After installing Ubuntu 12.04 and Bumblebee, I tested out the performance of the Nvidia card using Minecraft and a few other games. I've noticed it to be way slower than it was on Windows 7. Is this normal? I'm using the GT 630m. From what I've read online, nobody has said it to be slower than Windows. I'm just really curious because I want to use Linux so much more than Windows, but if I don't get the same performance I feel really picky. The Nvidia card is still faster than my Intel graphics on Ubuntu, but it's not as fast as it was for my on Windows. I get 60 - 80 fps on Minecraft on windows, while I get 28 - 48 fps on Ubuntu. Any Ideas why? Thanks so much!

• Freezes if desktop effects is used [closed]

  - by munir

  I have found that using desktop effects in Ubuntu versions later than 8.10 causes the desktop to freeze after a few seconds on my PC. the command lspci -nn gave the following 00:02.0 VGA compatible controller [0300]: Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2772] (rev 02) and with lspci -k I have 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) Kernel driver in use: i915 Kernel modules: i915 The intel graphics cards seems to have some performence issues with xorg driver. However I have not noticed any freeze in Ubuntu 8.10. There are some workarounds at https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes to make them work. But I can't find out what workaround should I do with my graphics controller. I have tried workaround F but it did not help. can anyone help me find a workaround for my graphics card? and is it actually possible to use desktop effect in this graphics card ?

• My laptop overheat on ubuntu 13.04

  - by Sina

  Overheating maybe is exaggerating word, but it's temperature is more in comparison with windows. My Graphic Card has failed for 2 time and I've paid money for each time. The problem makes me disappointed of keeping on ubuntu. Whenever I want to install "nvidia-current" my resolution becomes too low in screen and sometimes it just shows a dark screen. Is there any other Linux distribution which be more compatible with Hardware, specially Graphic Card? My Laptop is Dell Vostro 1510. And once This problem happened in 12.04 and another time days ago :(

• Assign programs permanently to different sound-outputs in Pulseaudio?

  - by Mood

  I want to assign Skype input and output to my USB-headset while the rest of my laptop uses the internal sound-card. This is an easy task with PulseAudio Volume control (pavucontrol). The only problem I have is every time a call is made I manually have to set the output and input for Skype to my USB-device . When I hang up, Skype disappears from Volume Control. It reappears again with the next call only this time the default sound-card is selected again. It shouldn’t be hard to let PulseAudio look or the USB-headset is connected when Skype audio comes is before selecting the default. The way to do it is obvious not through Volume Control.

• Is there a way to suppress one specific message from syslog?

  - by vava

  I'm getting a lot of Dec 27 08:35:49 htpc kernel: [ 1552.153797] pciehp 0000:00:1c.5:pcie04: Card not present on Slot(0-2) Dec 27 08:35:49 htpc kernel: [ 1552.157744] pciehp 0000:00:1c.5:pcie04: Card present on Slot(0-2) messages in my syslog, about 10 every second. That just makes syslog unusable, can I somehow get rid of them? I don't know and don't really care about the reason of those messages being there, partly because my motherboard doesn't have pcie slots on it and partly because everything I care about works perfectly. That might be a WiFi chip I disabled in bios but hey, I don't want wifi to be powered on, I'm not using it. So can I just suppress those messages?

• Major problem with Nvidia drivers

  - by user38580

  Since I decided to use Ubuntu -yesterday- I've been struggling with the drivers. It isn't recognizing my optical disc drive nor my video card, a Nvidia 8500gt. For the matter, here's how I "successfully" installed the .run driver downloaded from Nvidia's website: The terminal wouldn't let me start the installation because the X server had to be shutdown, so I pressed Ctrl+Alt+F1 Then, I used: sudo service lightdm stop cd /(directory where the nvidiaupdate.run was) chmod +x nvidiaupdate.run sudo ./nvidiaupdate.run The installation began and got completed, but unfortunately it crashed Ubuntu's UI, invalidating the OS for me. All that would appear was a DOS-like screen with reports. I'm new to Linux, so I really would appreciate any help given. For now, I'm sticking to the additional drivers, but even with it Ubuntu doesn't show my video card in the informations of the system. Forgive my bad English.

• Stuck on Ubuntu Startup Screen

  - by Pietro

  Since yesterday, my system won't get past the startup screen (the Ubuntu logo with the blinking red dots). I left it for over an hour and didn't get the login screen. It was working normally before that and I don't recall any changes (no new software, etc). I can login through the terminal with ALT+F1 but I don't know what to do to get the graphic mode. The command startx fails. I'm running Ubuntu 12.10 64 bits on a Core I5 with Intel motherboard. No video card or sound card.

• Can't connect to wireless network in Lubuntu

  - by mike

  I have a CISCO 802.11b WIFI Mini PCI LAN card in my IBM ThinkPad T30 laptop. Is this wireless card compatible with Lubuntu? I ran it off a Live CD and it showed the network I want to connect to – but it just won't connect. I tried installing Lubuntu and during installation it also tried to connect to the same network and still nothing. I know that the wireless network is working correctly because I can connect to it with all my other devices and it works on this very same laptop when I am running Windows.

  I am running Ubuntu 12.10 on a Sony Vaio VGC-RB34G ( http://reviews.cnet.com/desktops/sony-vaio-vgc-rb34g/4505-3118_7-31289053.html ) with an integrated Realtek High Definition Audio sound card. On Windows, I can set up the sound card to provide sound to my surround sound system from the Line Out, Line In, and Mic ports, as in all of these are producing audio. I have tried to use alsa to achieve this result with no luck. Is there any possible way to do this on Ubuntu? Thanks!

• Trust External Surround Soundcard SC-5500p not working

  I got the following external sound card to make some awesome noise with my speaker set. It should be plug and play, but it so happens that when I plug it in and hook everything up, there's no sound at all. The speaker set I have works if I plug it in the laptop directly (or rather, if I plug the front speakers cable as I can't plug anything else). http://www.trust.com/products/product.aspx?artnr=14134 Would anyone know how I can workaround this problem and make full use of this external sound card on my Ubuntu 12.04 system?

• Install/Downgrade kernel to v3.5.5 on Ubuntu 13.04

  - by Villi Magg

  I've been looking around the internet for a solution to downgrade the kernel from 3.8 to 3.5.5 since I've got the AMD/Ati Radeon Mobility HD 5600 graphic card on my machine. This video card in unfortunately not supported by the 3.8 kernel. And then when I've downgraded the kernel I need to install a version 12.* of the AMD Catalyst driver. There is too much in stake to wipe out the current installation of the OS and install an older OS. So I would like to avoid doing that to the ends of the world. Hope someone can help me with this one? Kind regards! Villi Magg.
