[arch-general] Implement sql/sqlite database for pacman local database
by Alive 4ever 23 Oct '16

23 Oct '16

I was curious why does 'pacman -Q' operations took longer than 'apt' counterparts. It seems that the local pacman databases are just subdirectories with text files (desc, files) and gzipped text (mtree). No wonder why local pacman databases tend to slow down over time and need to be optimized periodically. For long term pacman development road map, it would be better to use single sql based database for tracking locally installed packages instead of keeping directories of every installed packages. This would provide faster access for local database as sql databases are optimized for fast access.

One really big advantage of this approach is that you don't have to worry about corrupted databases. It's been a while since I used an RPM based distro, but it always surprised me how quickly the db would fall over and needed to be rebuilt. The beauty of the Arch approach is it's robust simplicity. And yes, there are/were wrappers that use a SQL DB for specific operations. If such a db gets problems, there is nothing to worry about: pacman just keeps working anyway. Just my two (belated) $0.02 Mvg, Guus

[arch-general] KVM - *ERROR* failed to allocate VRAM BO?
by David C. Rankin 21 Oct '16

21 Oct '16

Arch devs, I'm receiving an error with KVM (arch guest). The guest installed fine from the 20161001 install media, but between every command, I receive the following error: [TTM] Byffer eviction failed qxl 0000:00:02:0: object_init failed for (402650032, 0x00000001) [drm:qxl_alloc_bo_reserved [qxl1] *ERROR* failed to allocate VRAM BO The guest has 8G of storage gcow2 (default virt-manager settings, except scale on resize of window), 2-cores, 4G of RAM and the partitioning is all on a single / partition. I'm new to KVM and not sure whether this is something I should chase though my hardware (BIOS settings, etc.) or whether this is a KVM issue, the hardware is: AMD FX-8350 Black Vishera 8-Core 4.0GHz/32G of RAM/Gigabyte GA-990FXA-UD3 I've followed: https://wiki.archlinux.org/index.php/Libvirt https://wiki.archlinux.org/index.php/KVM https://wiki.archlinux.org/index.php/QEMU Where do I start in chasing this down?

[arch-general] Package updates for Long out of Date packages - comment
by Mike Cloaked 20 Oct '16

20 Oct '16

Not being able to post to arch dev public, and gaving seen that there was a list posted by Florian Pritz today with sets of packages that have been long out of date, I thought I would post a comment here about two particular packages that appear in that list. Having done some work privately recently on building refind-efi and gnu-efi-libs, I wanted to note that refind-efi was recently updated in the past few days, and is already at the latest version 0.10.4. I guess that Florian will already be aware of that? Gnu-efi-libs is also on the list but there is a very good reason that it has not been updated from version 3.0.3 to 3.0.4, which is that the newest version does not build for i686, at least when I tried to do that in an x86_64 machine using abs, even though it builds for x86_64, and that package is needed when building refind-efi so that would probably need an upstream fix before it can be brought up to date for both i686 as well as x86_64. -- mike c

[arch-general] Unlocking the screen through fprintd
by Bennett Piater 20 Oct '16

20 Oct '16

Hi all, I have been trying to get fprint working properly with screen lockers for months and have yet to find a working solution. I am using i3wm without DM. Login on the TTY and sudo work properly: They ask me to swipe the finger and then ask for my password if that didn't work. However, every screen locker I have tried that supports PAM at all (i3lock, xlockmore, xscreensaver, kscreenlocker) all ask for my fingerprint AFTER I typed in my password. Is there no way to make them check for my fingerprint first, and then for my password? Does anyone here do something similar? Cheers, Bennett -- GPG fingerprint: 871F 1047 7DB3 DDED 5FC4 47B2 26C7 E577 EF96 7808

[arch-general] German manpage for bash
by Ralf Mardorf 20 Oct '16

20 Oct '16

Hi, perhaps I'm "mad", but I wish to get a German manpage for bash and at least an English manpage how to write bash completions. Does anybody know a source for exotic manpages? [rocketmouse@archlinux ~]$ grep mad .bashrc alias mad='LANG=de_DE.utf8 man' [rocketmouse@archlinux ~]$ pacman -Ql man-pages | grep bash [rocketmouse@archlinux ~]$ pacman -Ql man-pages-de | grep bash [rocketmouse@archlinux ~]$ pacman -Ql bash-completion | grep share/man [rocketmouse@archlinux ~]$ pacman -Ql bash | grep share/man bash /usr/share/man/ bash /usr/share/man/man1/ bash /usr/share/man/man1/bash.1.gz bash /usr/share/man/man1/bashbug.1.gz The repositories seem not to provide the desired manpages.

[arch-general] system crashes when starting network connection
by sivmu 18 Oct '16

18 Oct '16

Hello, recently I have come across a weird problem regarding full system crashes under certain conditions. It seems somewhat random but the trigger always includes starting a network connection after sometime with no network connectivity. The only applications that have triggered the issue until now are firefox (after starting normaly) which triggers the second I click on a bookmark to open a website (no network conenction until that second). The other application was mutt, which triggered the moment when I fetched mails and the status bar said "looking up mbox" or something of the like. The result of the trigger is a full system crash, showing the current screen. Using Ctrl+Alt+F1/7 does not work. There is no trace in the logs, neither in the journal nor did I find anything with dmseg. The only way to get out of this is by hard reset. I have tried to replicate the bug but so far I was not succesful. I have no idea how to analyse the issue further. Do you have any hints on how to produce continious detailed logfiles or something of that sort to find what is wrong? Thanks

[arch-general] fluxbox/xscreensaver xterm unresponsive upon screensaver cancel?
by David C. Rankin 18 Oct '16

18 Oct '16

All, I'm not sure where to start searching on this problem. I have a server with fluxbox and xscreensaver enabled. If I'm running xterm when the screensaver activates, if I return after a couple of hours, the xterm is unresponsive. (instead of a normal solid black-box cursor, it is a white block cursor with a thin black outline) At this point, the xterm in non-responsive and I must kill the window with the [X] window control (top-right) and restart a new session. I note that if another application is left running, like firefox, then the xterm doesn't seem to hang or disconnect (or whatever it is doing). I don't know whether to chase this as an xterm issue, an xscreensaver issue or a DPMS issue. Has anyone encountered this before? If so, any solutions, or did you narrow it down to one of (xterm, xscreensaver, DPMS)? Thanks for any suggestions. -- David C. Rankin, J.D.,P.E.

[arch-general] sporadic strange PC speaker sounds
by J. C. 18 Oct '16

18 Oct '16

Hey hey, occasionally I hear a short "tune" on my pc speaker. It's too unexpected and too short to try lsof to see which process is using the pc speaker. The sound is reminiscent of old console games. It's several short notes, all in a blues pentatonic. this has been an issue right from the installation. The only special daemon running is brltty, which at least didn't use to make such sounds in the past. Can anyone suggest a process or a method of finding it? It only happens a couple of times a day, but this could be a problem when recording with the microphone. On the other hand, I can't turn off the pc speaker, since I rely on BRLTTY and other signals in non recording contexts. Thank you and best wishes, Jeanette -------- When you need someone, you just turn around and I will be there <3
