[arch-general] run boinc with optirun but no GPU found
by Stephen Zhang 14 May '15

14 May '15

Hi all, Today I installed boinc, and I'd like to run it with `optirun`. The first time I run `optirun bonic_client --dir /var/lib/boinc`, it showed me that `No usable GPUs found`. So, I installed `opencl-nvidia` package from the repo. After `opencl-nvidia` installed, I restart the boinc with optirun, it showed the same prompt. But after a suspend of my computer, it worked fine! the prompt became like this: ,------ 01-May-2015 11:36:53 [---] CUDA: NVIDIA GPU 0: GeForce GT 620M (driver version unknown, CUDA version 7.0, compute capability 2.1, 1024MB, 1009MB available, 240 GFLOPS peak) 01-May-2015 11:36:53 [---] OpenCL: NVIDIA GPU 0: GeForce GT 620M (driver version 349.16, device version OpenCL 1.1 CUDA, 1024MB, 1009MB available, 240 GFLOPS peak) `------ And a project began to use GPU to caculate as well. However, after I reboot my computer, the boinc can't find GPUs any more! The prompt is always `No usable GPUs found`. I also tried to write a simple CUDA program[1] to test if my CUDA device was ok, and the result was the CUDA program worked fine, it printed 'Hello CUDA!' as expected. My GPU model is NVIDIA GeForce GT 620M as mentioned above. My laptop model is Acer E1-471G 32352G50Mnks. I also have bbswitch installed, and `cat /proc/acpi/bbswitch` shows: ,------ 0000:01:00.0 ON `------ And here is the output of `lsmod |grep nvidia`: ,------ nvidia_uvm 73728 0 nvidia 8409088 1 nvidia_uvm drm 282624 6 i915,drm_kms_helper,nvidia i2c_core 53248 8 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,nvidia,v4l2_common,videodev `------ Anyone knows how I can run boinc with `optirun` correctly, or how I can run boinc with my GPU? Any reply will be appreciated! [1] https://cfp.vim-cn.com/cbSR/c -- Regards, Stephen

[arch-general] Linux kernel 4.0.2-1 flagged out-of date.
by Francis Gerund 14 May '15

14 May '15

Hi. Linux kernel 4.0.2-1 is flagged out-of date, just hours after release. But pacmatic keeps offering it as an update (along with other packages), with no warning message. I am using Linux kernel 4.0.1-1-ARCH (X-64). Should I go ahead and update, or wait for Linux kernel 4.0.3-1?

[arch-general] Why irrelevant updates?
by Francis Gerund 13 May '15

13 May '15

Sometimes pacman presents updates that just don't seem to apply to my system. Just one example: sudo pacman -Syyuv presents btrfs-progs, even though: 1) I do not, and have not, used the Btrfs file system with my Arch setup. 2) It is "Required by: None" 3) It is "Optional for: None" But I hate to reject it. After all, there must be some reason it was presented . . . right? So, if I just say "yes" to all upgrades, won't my system over time get weighed down by excess stuff, until it grinds to a halt? Or, if I just make my best guess at what is really need and reject the rest, won't I have a Frankenstein system that will eventually break? And why, why, why doesn't it just present upgrades appropriate for my system?

[arch-general] fresh install: netctl and interface renaming
by Łukasz Michalski 11 May '15

11 May '15

Hi, I am trying to setup network with netctl on fresh arch install. Netctl fails to start static profile due to different interface name. It looks like netctl is trying to start (twice?) before kernel finishes network interface renaming. What can be wrong?

Switching to the proprietary "nvidia" driver solved the problem. I'm still using the same computer and am now successfully using the "nouveau" driver on Arch, so presumably whatever was causing the problem in 2012 has been fixed.

I've had issues in the past with audio crackles that were caused by the video driver.

[arch-general] Headphone Sound Trouble

Hello everyone, since some days I am experiencing strange issues with my laptop headphone jack. When I boot into Windows 8.1, everything works as expected. No problems or cracking sounds. When I boot my Arch installation, it seems like everything breaks. My headphones randomly produce loud cracking sounds and when I manage to get something out of them, the sound is blurred and sounds disturbed. Searching the Asus FAQ's gave me: https://www.asus.com/en/support/FAQ/1009646 But I do not know how to check for these settings and wether this applies to me. Some system information: Hardware: Asus N550 JK Laptop uname -a: Konsole output Linux Goomba 4.0.1-1-ARCH #1 SMP PREEMPT Wed Apr 29 12:00:26 CEST 2015 x86_64 GNU/Linux pacman -Q alsa-utils: Konsole output alsa-utils 1.0.29-1 aplay -l : Konsole output **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: PCH [HDA Intel PCH], device 0: ALC668 Analog [ALC668 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 Thank you in advance for advices.

[arch-general] at times when booting system-logind fails and system hangs
by Javier Vasquez 08 May '15

08 May '15

I haven't identified under which circumstances, when booting the system hangs, and the only thing that can be related to that is the message: Failed to start Login Service Of course the recommendation to see the output of: systemctl status systemd-logind.service Is useless when that happens. That because the system hangs. A phisical hard power down is what I've done, and then usually by starting the system again everything works. Has anyone experienced this? Any suggestion? Thanks, -- Javier

[arch-general] PyChess Audio
by Grady Martin 08 May '15

08 May '15

Hello, all. Does anyone play chess? PyChess is great and seems mostly free of bugs now. There is one, glaring exception, but it could be specific to Arch. Sound effects do not play, and the sound files the pychess package installs to /usr/share/pychess/sounds do not appear in the sound selection dialogs (which have strange "untitled filters" applied to them). Should the problem be reported upstream?
