another nvidia driver problem

hello,

I've tried following the instructions posted to this list about a year ago
(http://ccrma-mail.stanford.edu/pipermail/planetccrma/2014-April/018347.html)
to try and get nvidia graphics working. But after I install akmod and reboot I
can't login any longer. I had to move the nvidia config files (*) in order to
be able to login.
any idea how I track the problem and possibly get the driver working? 
Also in the process I lost the option of 1440x900 screen resolution so the
image is stretched. Any clues how I can restore that resolution option if
fixing the drivers doesn't work?
thanks

(*) mv /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
mkdir /etc/X11/nvidia-backup && mv /etc/X11/xorg.conf.d/*nvidia* 
/etc/X11/nvidia-backup

Is there a planetccrma-repo-1.1-3.fc21.ccrma.noarch.rpm

Hi

Is there a planetccrma-repo-1.1-3.fc21.ccrma.noarch.rpm so i can install yum repos.

Or what kind of config should i write into /etc/yum.repos.

Re: external soundcard future

USB is fine as long as you don’t have to use 44.1 or 88.2 - USB soundcard frames are 1ms long, so if there’s a
non-integer number of samples per ms you get variable sized frames, which is… yuk!

i went to f20 because of the ccrma repo's. i noticed that the last (work in progress) was the version 20 so i
went for that...
also noticed that the pd-extended is buggy... doesnt load pdp or gem libs and doesnt respond to the quit
program command.

problems with cpupower under ccrma kernels for Fedora 20

Hi,
I'm having problems setting the cpu frequency governors when running under a ccrma RT kernel - I've tried several different ccrma rt kernels with no success.

Basically cpupower works under all my stock Fedora 20 kernels, but does not work under any of the ccrma RT kernels. cpupower frequency-info shows the governors, but cpupower frequency-set returns an error. The system defaults to "powersave" and I need to have it in "performance". I have a startup script that is supposed to set the governor to 'performance' on boot up, but it fails when booting a ccrma kernel. Has anyone else had similar problems?

For example (CCRMA RT Kernel):

root <at> iris ~]# uname -r
3.14.29-200.rt26.1.fc20.ccrma.x86_64+rt
[root <at> iris ~]# cpupower frequency-info
analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 0.97 ms.
  hardware limits: 800 MHz - 3.00 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 800 MHz and 3.00 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency is 804 MHz (asserted by call to hardware).
  boost state support:
    Supported: yes
    Active: yes
    2700 MHz max turbo 4 active cores
    2700 MHz max turbo 3 active cores
    2900 MHz max turbo 2 active cores
    3000 MHz max turbo 1 active cores
[root <at> iris ~]# cpupower frequency-set -g performance
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?
[root <at> iris ~]# modprobe cpufreq-performance
[root <at> iris ~]# cpupower frequency-set -g performance
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?

As you can see, I am running as root, the governor is available and modprobed, it is a valid policy, and I'm not trying to set a specific frequency. Obviously not a common error and it is particular to the CCRMA Fedora 20 kernels

For reference, I rebooted the machine into a stock Fedora 20 kernel:

[root <at> iris john]# uname -r
3.18.7-100.fc20.x86_64
[root <at> iris john]# cpupower frequency-info
analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 0.97 ms.
  hardware limits: 800 MHz - 3.00 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 800 MHz and 3.00 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz (asserted by call to hardware).
  boost state support:
    Supported: yes
    Active: yes
    2700 MHz max turbo 4 active cores
    2700 MHz max turbo 3 active cores
    2900 MHz max turbo 2 active cores
    3000 MHz max turbo 1 active cores
[root <at> iris john]# cpupower frequency-set -g powersave
Setting cpu: 0
Setting cpu: 1
Setting cpu: 2
Setting cpu: 3
Setting cpu: 4
Setting cpu: 5
Setting cpu: 6
Setting cpu: 7
[root <at> iris john]# cpupower frequency-set -g performance
Setting cpu: 0
Setting cpu: 1
Setting cpu: 2
Setting cpu: 3
Setting cpu: 4
Setting cpu: 5
Setting cpu: 6
Setting cpu: 7


Can anyone provide a suggestion of how to proceed ?

John

fedora 20

hello, 

i just installed fedora 20 lxde on my laptop, following an install of the planetccrma repository but now i arrived at a point where i don't understand what is going on with my audio setup entrails---is it pulse audio, alsa or jack server that are controlling the thing?
thank you in advance

external soundcard future

Dear all,
I am wondering if anyone knows what the future of good soundcards looks like. At 
the moment I rely on expresscard connectors (RME + an old focusrite using 
firewire). I started realising that most new laptops don't have expresscard 
slots any longer so this option seems to be closing. Does anyone have any 
experience getting sound working through a USB<-expresscard adapter? Or should I 
hurry up and buy a new laptop (my current one is 7 YO) before I ran out of 
options? Would new soundcards being developed use USB3? Or? 
 thanks
Oded

snd-firewire-improve works perfectly with Focusrite Saffire PRO 24 (dice based audio interface)

Hi,

After wasting 5 unsuccessful weeks trying to get ffado to work, i tried back porting the alsa snd-firewire-improve modules using the procedure described on:

https://github.com/takaswie/snd-firewire-improve

I found that:
  • The modules built perfectly.
  • The Focusrite Saffire PRO 24 is detected on-plug in.
  • Using QjackCtl, jackd started and run correctly using alsa as the driver and PRO 24 as the interface.
  • All the PRO 24 audio ins and outs could be routed to/from Ardour3.
  • Ardour3 records unendlessly without a single XRUN.

This is truly a cool piece of programming - Takashi Sakamoto seems to have done it again...


Cheers, Simon

lots of xruns with 3.14.29-200

I'm not sure if this is effecting anyone else, but kernel-rt-3.14.25-200.rt22.1.fc21.ccrma.x86_64 runs perfectly w/ Ardour & Mixbus. Moving to kernel-rt-3.14.29-200.rt26.1.fc21.ccrma.x86_64 with no other variables, results in an unusable amount of xruns. Roughly between 10 to 30 a minute.

I am using a focusrite usb interface, and haven't had much time to investigate, but I'm throwing this out there in case anyone else is running into it.

Cheers,
Ben

pd-extended for Fedora 21?

Hi,

I've noticed that there were issues with building pd-extended for Fedora 21. A locally build pd-extended complains about the missing wish8.5 (8.6 is packaged in F21). Has anyone successfully build/packaged pd-extended for F21? Has anyone made progress in packaging it for planetccrma?

Kind regards,
Felix

Patch for lowering number of ports of Linuxsampler LV2 Plugin

Hi,

due to the new version of linuxsampler the plugin has 32 output ports 
instead of 2. I think 2 would be a much more sane number as most samples 
are stereo. Ardour looks very cluttered with a 32 ports plugin.

Fernando, could you add that patch I attached? I took it from the ardour 
mailinglist.
