[arch-general] rtirq
by Ralf Mardorf 18 Sep '12

18 Sep '12

Not a serious issue. # pacman -Syu rtirq [snip] ==> This script works only in conjunction with a realtime kernel. [snip] It at least does work with full preempt kernels + threadirqs too. Regards, Ralf PS: Apologize, but I don't know if you're following arch general, that's why I "cc"ed it. # pacman -Qil rtirq Packager : Bernardo Barros

[arch-general] Modifying archiso
by Robbie Smith 18 Sep '12

18 Sep '12

The wiki gives instructions on modifying the ISO[1] and the last step is to recreate the actual ISO file. I've got my Arch installers on USB sticks, but is it absolutely necessary to do this? Couldn't I just copy the root-image.fs.sfs to the appropriate directory on my USB (/path/to/USB/device/arch/x86_64/root-image.fs.sfs) instead, and regenerate the checksums?

[arch-general] installation file format question
by Jude DaShiell 18 Sep '12

18 Sep '12

What is the command to put xfs file formatting on partitions? I have arch on a separate disk so can try an installation with xfs probably tomorrow morning. --------------------------------------------------------------------------- jude <jdashiel(a)shellworld.net> Adobe fiend for failing to Flash

[arch-general] /etc/tmpfiles.d
by Martín Cigorraga 18 Sep '12

18 Sep '12

"[...]However, tmpfiles may also be used to write values into certain files on boot. For example, if you use /etc/rc.local to disable wakeup from USB devices with echo USBE > /proc/acpi/wakeup, you may use the following tmpfile instead: /etc/tmpfiles.d/disable-usb-wake.conf w /proc/acpi/wakeup - - - - USBE The tmpfiles method is recommended in this case since systemd doesn't actually support /etc/rc.local." Does that means that I need to move all the content from /etc/rc.local to /etc/tmpfiles.d? For example this is my actual /etc/rc.local: ~ $ cat /etc/rc.local #!/bin/bash # # /etc/rc.local: Local multi-user startup script. # #modprobe radeon # added by hybrid-video-ati-intel install script #echo IGD > /sys/kernel/debug/vgaswitcheroo/switch # added by hybrid-video-ati-intel install script echo OFF > /sys/kernel/debug/vgaswitcheroo/switch # completely deactivate radeon ## ATi # Source: https://wiki.archlinux.org/index.php/ATI#Performance_tuning echo low > /sys/class/drm/card0/device/power_profile #echo profile > /sys/class/drm/card0/device/power_method echo dynpm > /sys/class/drm/card0/device/power_method echo OFF > /sys/kernel/debug/vgaswitcheroo/switch # CPUFREQ for i in 0 1 2 3; do cpufreq-set -c $i -g powersave; done ## sets powersave cpufreq governor for all CPU cores #echo -n 90 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold echo -n 20 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor # Prepare the system for Wake-on-Lan /usr/sbin/ethtool -s eth0 wol pg # Activate laptop_mode echo 5 > /proc/sys/vm/laptop_mode # Performance tweaks for USB drivers under KDE SC echo madvise > /sys/kernel/mm/transparent_hugepage/enabled echo madvise > /sys/kernel/mm/transparent_hugepage/defrag echo 0 > /sys/kernel/mm/transparent_hugepage/khugepaged/defrag If this is the case, how do you guys would convert the FOR loop!?

[arch-general] HARDWARECLOCK and systemd
by Martín Cigorraga 17 Sep '12

17 Sep '12

I'm moving to systemd (finally!) and I'm stuck at the HARDWARECLOCK section of rc.conf wiki. How should be configured /etc/adjtime ? I can't find what should be inside it. Also there say: " If this value is not set, then the value stored by hwclock in /var/lib/hwclock/adjtime [...]" but I don't have any /var/lib/hwclock directory. I would appreciate if anyone who already did the jump can share his experiences, thanks!

[arch-general] Munin and MySQL
by Martín Cigorraga 17 Sep '12

17 Sep '12

Hi all, anyone proficient at Munin? The talk of one of our guest speakers at the local SFD that took place yesterday was about monitoring everything with Munin, a software I didn't knew but which I liked at first sight. Once at home the very first thing I did after take the laptop out of my backpack was install Munin, of course, and alongside this I found some warning and error messages that aren't very informative so before go and dive on the net trying to gather information about them I decided to first try luck in the list. Whenever I run: # munin-node-configure --shell | sh I got this: # The following plugins caused errors: # mysql_: # Non-zero exit during autoconf (2) # ntp_states: # Non-zero exit during autoconf (2) # proc: # In family 'auto' but doesn't have 'autoconf' capability Now the munin-node-configure --suggest command shows: | no | no for all the three plugins. Following the wiki suggestion: # munin-run {plugin} I got a: # Unknown service '{plugin}' for all them three. I would appreciate any light here since seems there isn't any Munin error log file to check and also Munin does not log to standard /var/log/errors.log file. Greetz, Martin

Re: [arch-general] almost got latest talkingarch installed
by Jude DaShiell 16 Sep '12

One thing I forgot to write up. After booting into new system, hitting keys on keypad does not crash the system and those keys perform the expected speakup functions so the system is definitely using linux-lts and not the flake default kernel. --------------------------------------------------------------------------- jude <jdashiel(a)shellworld.net> Adobe fiend for failing to Flash

Re: [arch-general] almost got talking arch installed
by Jude DaShiell 16 Sep '12

I put the fixes in on /boot/syslinux/syslinux.cfg and was successful in First running initcpio -p linux-lts had no problems running and I pointed everything to linux-lts in /boot/syslinux/syslinux.cfg. Then I rebooted the system. I let the computer alone for 8 hours then returned and hit enter to get archlinux talking. I managed to login as root and was told the file system was read only. I checked /dev/sda1 and /dev/sda3 with ls -al and in both cases got the attribute string back of brw-rw----. I replaced the arch disk in the drive sled with a working install of debian and after boot up checked /dev/sda1 with ls -al and got the attribute string back of brw-rw---T. So the latest talking archlinux over here using syslinux turns out to be installable and unusable at least for the moment. Is this salvageable, I don't know this is the first time anything like that happened in my experience with Linux. This time, I can't produce any dmesg output given the state of the disk and probably the boot process either. --------------------------------------------------------------------------- jude <jdashiel(a)shellworld.net> Adobe fiend for failing to Flash

[arch-general] Using install dual iso 2012-09-07 - graphics issue?
by mike cloaked 16 Sep '12

16 Sep '12

I have made a bootable usbkey with the archlinux-2012.09.07-dual.iso file but having tried to boot it, both on an Inspiron 530s and also a Samsung Q35 netbook, there is a blue "graphics" screen but it does not stop and offer me the choice of i686 or x86_64 but carries straight on to boot to the normal prompt. So I can't choose which architecture to use for the install. Does anyone know a workaround to be able to get to choose which of 32 or 64 bit to boot for the install? Or is there a problem with this new install media on some hardware? I have done quit a bit of reading but not seen this issue mentioned in any of the arch wiki or other google searches. Thanks -- mike c
