[arch-general] Problem with NFS on shutdown
by Paul Marwick 13 Feb '13

13 Feb '13

I've got two machines in my local network that provide NFS shares. One is an old Raidsonic NAS (running a current version of OpenWRT), the other a dedicated server running Slackware). I normally mount the shares manually (the machine that is giving me a problem is a laptop, so its often not connected to my own network). The problem comes when I try to shut the laptop down (or restart it). Unless I've manually unmounted the NFS shares, the machine will hang and fail to shut down. In some instances, I've been able to use CTRL-C to break out of the stall, but frequently, I can only turn the machine off, which is not exactly ideal. I've been playing with the nfs exports, currently have the following: /mnt/sda2/stor 192.168.1.0/255.255.255.0(rw,sync,no_wdelay,nohide,no_root_squash) (this is on the Raidsonic) and /mnt/sda2/stor 192.168.1.0/255.255.255.0(rw,sync,no_wdelay,nohide,no_root_squash) on the Slackware server. The problem is specific to Arch - I've got two other distros installed on the laptop (though Arch is my usual OS). From SalineOS or Salix, the laptop will shut down or restart without having to manually unmount the NFS shares prior to shutdown. I suspect I've not got something set up correctly in systemd, but I'm currently at a loss to work out what. If I manually unmount the shares before shutdown, there is no problem. I've also tried adding the unmount to /etc/rc.local.shutdown, but that doesn't work - the system still hangs during shutdown. I'm sure that rc.local.shutdown is being executed - if I shut down without the shares mounted, I can see messages that they are not mounted. I'm not sure if I should be looking at the NFS export parameters on the hosts, or systemd on the laptop, though I've tried some variations on the exports without changing the behaviour. Does anyone know what I should be looking at to solve this? Paul.

[arch-general] Failed to give slave programs access to the display
by Leonidas Spyropoulos 10 Feb '13

10 Feb '13

Hi all, I have a strange problem with my GDM. The problem started when I got a new monitor combined with updates. First I got a new monitor and connected (switching from DVI -> VGA cable to DVI -> DVI cable). It was different resolution as well 1900x1200. At the same session (ans without restarting) I upgraded after a week or something with the new kernel 3.7.6-1-ARCH and latest nvidia drivers 313.18.3-3. After that point the gdm starts (but slower than before) and as soon as I put my password and tried to start my session, the background image is lost (turns to black) I see some flickering and the Gnome-shell session loads but I can't access anything. I had this problem before randomly so I didn't pay attention but now it's consistent. I can move the mouse around without affecting the Gnome-shell though. journalctl [1] shows the above message along with NVRM errors right after I login. I tried downgrading to lower kernel and nvidia drivers but it didn't help as I cannot load the nvidia driver when I downgrade (I think I need to rebuild the nvidia kernel module and don't know how). I tried deleting the .config, .gconf, gnome2, gnome2-private, .nv folders from my home folder in case it was configuration but nothing. Anyone have some suggestion?

Downgrading cairo to [core] fixes that for me (and allows me to build things again) but the one in testing somehow breaks pkg-config.

[arch-general] HDMI Alsa sound problem from flashplayer 64 bit
by Mike Cloaked 10 Feb '13

10 Feb '13

I have a machine which has an HDMI monitor and which has sound coming through the monitor via HDMI just fine when playing music from Amarok and login system sounds play fine too. I had selected the appropriate hdmi channel in kmix for all the available audio playback devices. Also I can get sound coming out of the monitor speakers with: aplay -D plughw:0,7 /usr/share/sounds/alsa/Front_Center.wav However if I run chrome and play a flash video the video I can see fine - but there is no sound. I have read all the available arch wiki articles about hdmi sound including that at https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#HDMI… as soon as I make a ~/.asound file with either of the suggested contents KDE immediately tells me that the hdmi sound for that output has been selected to be removed and offers me to make that permanent! This is for an x86_64 arch system all up to date - and I have flashplayer installed. Can anyone guide me as to where to look for a solution that will get this particular system playing sound from flash content on web pages in chrome? I have several other (non-hdmi) systems which have no problem with sound from web pages playing flash content. Thanks -- mike c

If this is a good solution shouldn't that permission be set that way when the bind package (bind 9.9.2.P1-1) is initially installed, so that it does not then need changing after the install? -- mike c

[arch-general] [SOLVED] HDMI Alsa sound problem from flashplayer 64 bit
by Mike Cloaked 08 Feb '13

08 Feb '13

I promised I would post when I had this hdmi sound problem resolved - after a while spent trying to sort this out today I have now it working, and it may be useful to list the details in case anyone else has had a similar issue getting sound from flashplayer videos running in the chrome browser. I installed pulseaudio along with three other packages: # pacman -S pulseaudio paprefs pavucontrol pulseaudio-alsa I also noticed that I needed one of the gstreamer plugin packages that I had inadvertently missed when I had previously installed the initial set of packages via a simple script. # pacman -S gstreamer0.10-good-plugins It is possible that my failure to get things working with alsa alone may have been due to not having this package installed before. However once the following settings had been put in place all sound now works properly and well: >From the KDE desktop, In Kmix under Audio Hardware setup: selected: Builtin audio Sound Card, with: Profile - Digital Stereo (HDMI) Output + Analogue Stereo Input and under Device configuration selected: Playback (Builtin Audio Digital Stereo (HDMI)) with Connector HDMI/Displayport. Then under Device preference chose Builtin Audio Digital Stereo (HDMI) for all the output types. Sound works now on all applications including from flashplayer video with audio within the chrome browser. It is entirely possible that if I had installed the gstreamer0.10-good-plugins package at the outset that there may not have been a problem at all and therefore this may have been just as much an issue with all sound connections. Thank you for the replies to my original post and for suggesting that I change from alsa to pulseaudio. The controls both in pavucontrol and the now changed controls in kmix with pulseaudio are better than with alsa. -- mike c

[arch-general] How to wait efficiently for a package to update?
by Oon-Ee Ng 08 Feb '13

08 Feb '13

So I'm checking out python-sympy for some calculations in the Robotics subject I teach and realized that a bug was recently fixed in git which is crucial to what I hope to use it for. python-sympy-git in the AUR and that's settled. Then I got to wondering, I only really want to use the -git version till the next release, but since python-sympy is no longer installed (conflicts) I wouldn't automatically get it unless I check every once in a while if version is > 0.7.2. I figured installing a blank package with nothing in package() named python-sympy and with version 0.7.2 would allow me to get notified when python-sympy-0.7.3 or later gets in the repos. Is this a good way of doing it, or are there better ways?

[arch-general] RFC: Catalyst and Hybrid Graphics
by Armin K. 08 Feb '13

08 Feb '13

Hello, I have been playing with Catalyst on ArchLinux in order to get my Hybrid Graphics working. Catalyst supports PowerXpress 4.0+ in Linux, so muxless graphics can work. It took me some time to get it to work, I had to workaround many stuff. Here follows: First thing that I was bothered with is that /usr/lib/fglrx/switchlib{GL,glx} were missing. Their purpose is to switch /usr/lib/libGL.so.1 and /usr/lib/xorg/modules/extensions/libglx.so to either AMD (Catalyst) or Intel (Mesa and Xorg) libraries. Each one is called with "intel" or "amd" as an argument, and both must exit sucessfully with "echo amd" or "echo intel" after getting the job done. I've managed to "fool" Catalyst by creating dummy files. #!/bin/bash echo amd exit 0 By default, aticonfig --initial will use AMD (Discrete) GPU, so the current installation seems to be okay. I'll continue with other issues that can arise later in this mail. Next major problem is that fglrx will load intel driver, which, unfortunately can't be installed by default since it depends on intel-dri, which depends on libgl which is in conflict with catalyst-utils package (doh). I had to rebuild it without intel-dri dependency to get this working. On why intel driver is necesary, I can answer the following: Most newer hybrid graphics are muxless, they do not have hardware multiplexer and you can't select on which GPU you want to output. Instead, Discrete GPU is just wired to Integrated one and is meant only for Processing while it is on Integrated GPU to display anything passed from the Discrete GPU. For more information on this term, you may want to look at DRI PRIME and DMA BUF (An open source solution for this mess). So in fact, intel driver is needed since it is used for 2D and stuff, where fglrx only does the encoding/decoding stuff. How to fix it? Well, I couldn't think of any nice way to fix this. Debian has their alternatives system so they can have multiple libGL installed and set with alternatives. Gentoo does the same with their eselect stuff or whatever it's called. Since aticonfig --px-dgpu tells xorg.conf to use Discrete (AMD) GPU, it also runs /usr/lib/fglrx/switchlib{GL,glx} with "amd" as parameter in order to "make" /usr/lib/libGL.so.1 and /usr/lib/xorg/modules/extensions/libglx.so point to AMD provided libraries. aticonfig --px-igpu would switch to Mesa libGL.so.1 and Xorg Server libglx.so which are, you know, not present when catalyst-utils are installed. (Xserver libglx.so is present, but it's useless without Mesa's libGL.so.1). On how to solve this I can only think of making another package (part of Mesa source package) called something like intel-dri-hybrid (which depends on catalyst-utils and can only be used with it) that installs Intel DRI drivers and libGL.so.1 into some nonstandard place or just renamed to something else like libGL-intel.so.1. Also, it would be necesary to make /usr/lib/fglrx/switchlib{GL,glx} to correctly switch (symlinks should do it, but carefully) between AMD and Open Source libGL and libglx. I haven't done this yet but some may want to use this - not everyone wants to use Discrete GPU always - especially when on battery. I can say that power consumption on my laptop has dropped even though I always disabled Discrete GPU via vgaswitcheroo (radeon driver). Any comments and suggestions are welcome. I can try to implement something if necesary, it's just the question if my suggestions are good enough and will be accepted. I appologize for any gramatical mistakes.
