[arch-general] Komodo Edit
by James 23 Aug '15

23 Aug '15

I installed Komodo Edit and I want to put a quick launch button on my task bar but it doesn't show up in the list of "installed applications". That is weird because it shows up in the "Menu" in the "Programming" section. I use lxde.

[arch-general] mdmonitor.service - fails to start/load?
by David C. Rankin 23 Aug '15

23 Aug '15

All, I'm not sure if this is a config issue or bug. I have 2 servers with mdadm/mdraid arrays. In both a check of 'systemctl --type=service' shows mdmonitor has failed. It fails to start each time: ● mdmonitor.service - MD array monitor Loaded: loaded (/usr/lib/systemd/system/mdmonitor.service; static; vendor preset: disabled) Active: failed (Result: exit-code) since Sat 2015-08-22 22:33:52 CDT; 7h ago Process: 377 ExecStart=/sbin/mdadm --monitor $MDADM_MONITOR_ARGS (code=exited, status=1/FAILURE) Process: 375 ExecStartPre=/usr/lib/systemd/scripts/mdadm_env.sh (code=exited, status=203/EXEC) Main PID: 377 (code=exited, status=1/FAILURE) Looking at the service file I'm not sure if there is an issue here, or somewhere else, but there is no file 'mdadm_env.sh' that is reference by ExecStartPre=: # This file is part of mdadm. # <snip> [Unit] Description=MD array monitor DefaultDependencies=no [Service] Environment= MDADM_MONITOR_ARGS=--scan EnvironmentFile=-/run/sysconfig/mdadm ExecStartPre=-/usr/lib/systemd/scripts/mdadm_env.sh ExecStart=/sbin/mdadm --monitor $MDADM_MONITOR_ARGS Is this a bug? -- David C.

[arch-general] weechat installs to /usr/local
by Jagannathan Tiruvallur Eachambadi 20 Aug '15

20 Aug '15

HI The weechat package now installs to /usr/local after the recent update. Can the maintainer look into it. I looked into the PKGBUILD, but there is no change in the way the package is compiled. Only sources have been updated. Regards Jagan

[arch-general] debug package repositories again
by Joe Julian 15 Aug '15

15 Aug '15

It's been hashed and rehashed, but I need to bring this up again. Every other popular distro has a way of debugging without completely rebuilding a package, saving countless combined hours. Why can't we just have a way of installing the symbols? When I find a bug, I don't want to spend another hour building python, for instance. I want to install the symbols, open up gdb, and figure out where the problem is. I'll report it, probably fix it, and we'll all be happy. Allan has already added the features necessary to make this possible. Why is this so hard? What can I do to help make this a reality? https://lists.archlinux.org/pipermail/arch-dev-public/2013-April/024812.html https://lists.archlinux.org/pipermail/arch-general/2015-April/038794.html

[arch-general] Extremely slow battery status on MBP
by Emanuel Evans 14 Aug '15

14 Aug '15

Hi! I have kind of a weird issue that I'm having trouble debugging. On my MacBook Pro (11,1), checking battery status (through acpi or the /sys filesystem) becomes extremely slow after the computer's been on for a while. Here's an example: $ time cat /sys/class/power_supply/BAT0/status Charging real 0m54.519s user 0m0.000s sys 0m4.663s dmesg and journalctl aren't outputting anything during the call, and I tried strace during the command and there was no output during the blocked time. It's highly intermittent--acpi can take anywhere from 0-60 seconds with no discernible pattern. Any ideas for how to debug this further, or possible solutions? Thanks so much!

[arch-general] motherboard change - strategies for saving current install?
by David C. Rankin 13 Aug '15

13 Aug '15

All, I lost the disc controller in my arch server this past Sunday. I've ordered a replacement w/new processor, etc.. My question is what is the best strategy to save my current install? It's a simple: "can I boot the install media, assemble raid arrays, chroot old and update, or do I just dump the root partition and reinstall completely?" The hardware change will be from an AM2+ MSI board with Phenom 9850 to a Gigabyte AM3+ board with FX8350 if that matters. The primary goal is to preserve the raid arrays and server config for mail, web, etc... I know I can chroot, save the needed configs, reformat root and reinstall, but what I don't know is if there is an easier way that would avoid the reformat/reinstall of root? This will also be by first UEFI install, but I'm fairly certain the beginner's guide will get me through if a full reinstall is needed. However, does that have implications on being able to save the old partitions and my mdraid arrays? The current setup was a simple MBR, mdraid1 with grub2. I don't have a EFI system partition, but I believe I left space at the end of my arrays (I'll have to check if it is a full 512 MiB). I don't know if I can salvage that setup by adding the EFI system partition at the end? Reading from the beginner's guide: "The target drive requires a GPT partition table, and an EFI System Partition of at least 512 MiB in size, gdisk type EF00, and formatted with FAT32." That seems to indicate that any chance of salvaging my current install may be hopeless due to the current MBR partition table. If there is a link that covers this in the wiki, I apologize, I haven't found it yet. Thanks for any advise or helpful tips you can give. -- David C. Rankin, J.D.,P.E.
