[arch-general] Building in docker?
by Magnus Therning 27 Apr '16

27 Apr '16

For various reasons I'm looking into not using `makechrootpkg` when building the 200+ packages I put into a non-official repo. Obviously it's important to keep the building environment separate from my ordinary system environment. Going to full virtualisation is definitely overkill and the only containers I know of are chroots and docker. Docker has some nice attributes, in particular no need for root access. However, I don't know a whole lot about it, so I wonder are there any aspects to it that makes it a bad choice for building packages? /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus Heuristic is an algorithm in a clown suit.

[arch-general] Smartcard troubles on Arch
by Mathias Huber 18 Mar '16

18 Mar '16

Dear Archers, I am trying to get my Gemalto USB Shell Token V2 (GPG-Smartcard-Reader in a USB-Stick) to work on Arch. I've set up Udev in the way I did successfully in Ubuntu 12.04.LTS. However, no success. I am still trying to figure out where the trouble lies. I can never see the card using gpg --card-status But sometimes I see its fields when using pcscs_scan. Possible culprits: pcscd, which sometimes gives errors, gpg's USB support? Has anyone had success in setting up this reader or similar smartcard readers? Or had similar troubles? I would love to hear from you. Best, Mathias

[arch-general] Additional mouse (Lenovo N700) gesture binding
by Oon-Ee Ng 06 Aug '15

06 Aug '15

I just got the above bluetooth and/or wireless (dual-mode) mouse for my work, as the presenter laser looked pretty useful. 3 basic buttons (1, 2, 3) worked out of the box. So did the touch-scrolling (up/down). So I'm looking for advise for the remaining 3 inputs supported. This mouse has a 'Windows key' button and supports left/right swipe gestures (targeted at the new Windows side-screen gestures). Firstly, regarding the gestures, here's what I obtain from xinput test. I've also listed which keys these correspond to. Left swipe:- key press 22 Backspace key press 133 Super_L (left Windows key) key press 37 Control_L key release 22 Backspace key release 133 Super_L (left Windows key) key release 37 Control_L Right swipe:- key press 54 c key press 133 Super_L (left Windows key) key release 54 c key release 133 Super_L (left Windows key) This seems to correspond to pressing 3/2 key combos and releasing them in the same order. This seems to cause problems with xbindkeys and sxhkd (the only two key-binding daemons I've used before) as using the Super-c combo expects the Windows key to be pressed first, followed by the c key being pressed and released. How can I bind gestures to the above? Is it possible, for example, to bind keys to a specific input device (so for example I can bind to the letter c but only from the mouse, not from my keyboard)? Or something involving xmodmap? Thanks for your advise/help.

[arch-general] Possibility of including xorg input patch
by Kirill Churin 25 Jul '15

25 Jul '15

Can this patch https://bugs.freedesktop.org/attachment.cgi?id=33142 be applied to Arch's xorg? It solves famous problem https://bugs.freedesktop.org/show_bug.cgi?id=865 with broken keyboard input for users who use multiple keyboard layouts without any noticeable side-effects. It's known this patch has been applied in Ubuntu. -- Kirill Churin Jabber: reflexing(a)reflexing.ru, ICQ: 8163230, Skype on demand.

[arch-general] "error: unknown encoding UTF8: using iso88591 as fallback"
by Ralf Mardorf 31 May '15

31 May '15

Hi, for some time past I get error: unknown encoding UTF8: using iso88591 as fallback when running GTK2 and GTK3 apps, Pluma, Claws Mail, Evolution. Other apps, perhaps Qt apps, might be affected too. There are no issues when using those apps, the terminal just shows these messages. [rocketmouse@archlinux ~]$ locale -a C de_DE de_DE@euro de_DE.iso88591 de_DE.iso885915@euro de_DE.utf8 deutsch en_GB en_GB.iso88591 en_GB.utf8 en_US en_US.iso88591 en_US.utf8 german POSIX [rocketmouse@archlinux ~]$ cat /etc/locale.conf LANG=en_US.UTF-8 [rocketmouse@archlinux ~]$ cat ~/.config/locale.conf cat: /home/rocketmouse/.config/locale.conf: No such file or directory [rocketmouse@archlinux ~]$ sudo nano /etc/locale.conf [rocketmouse@archlinux ~]$ cat /etc/locale.conf LANG=en_US.utf8 [rocketmouse@archlinux ~]$ sudo shutdown -r now It doesn't make a difference, I still get the error messages, when running a new session. Regards, Ralf

[arch-general] Fwd: Connection through USB to TTL Serial Cable
by Csányi Pál 31 May '15

31 May '15

I also used sofar the GNU Screen to connect to remote host through serial connection: screen /dev/ttyUSB0 115200 Sofar it works, but today I get the message: [screen is terminating] htop shows these lines for screen: 19038 csp 20 0 17244 2496 2300 S 0.0 0.0 0:00.00 screen /dev/ttyUSB0 115200 19039 root 20 0 17244 2348 2044 S 0.0 0.0 0:00.00 SCREEN /dev/ttyUSB0 115200 So I must first kill these two processes of screen, and after that I can run screen /dev/ttyUSB0 115200 command, however, the GNU Screen is empty, so it is useless. Before, I just hit Enter to get the login prompt in Screen, but now I get nothing. Ti trace the cause of problem I follow advices here: http://unix.stackexchange.com/questions/93892/screen-is-terminating sudo strace -ff -p 1696 -o straceGNUScreen gives three output files: http://pastie.org/10215997 http://pastie.org/10216006 http://pastie.org/10215998 What can cause my problem? -- Regards from Pal

[arch-general] Subpixel antialiasing
by Vladimir Nikšić 28 May '15

28 May '15

Hi guys! I've done a pacman -Syu this morning. The upgrade went fine, all the key components are working properly, except a slight issue I'm having with chromium. Chromium no longer obeys the subpixel antialiasing, but instead has a basic AA mode, without the subpixel hinting. This of course results in ugly letters across the board. What's even more weird, other applications seem to have it normally, like firefox, xfce4-terminal, etc... I'm using xfce4. The settings > appearance had subpixel disabled, but once enabled chromium still didn't obey the subpixel hinting. I don't understand what has changed exactly with chromium, and how do I set it to have subpixel once again. I went through here https://wiki.archlinux.org/index.php/Font_configuration#Subpixel_rendering but I can't really find anything pertinent to my case. Any ideas anyone? :)

[arch-general] systemd 220 crypt swap
by Carsten Mattner 27 May '15

27 May '15

I had to downgrade to systemd 219 because 220 fails to stop or enable luks crypt swap partition. There was an unlogged error on shutdown after upgrade and an infinite loop/wait on startup. I had to use a rescue linux to mount and disable crypttab and fstab entries before downgrading. /etc/crypttab: cswap /dev/sda3 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256 /etc/fstab: /dev/mapper/cswap none swap defaults 0 0 Found nothing relevant about API breakage in v220 changelog.

[arch-general] RAID-0 kernel bug
by Francis Gerund 27 May '15

27 May '15

Hello. RE: "Data corruption on software RAID 0 when discard is used 2015-05-22 Recent Linux kernels (4.0.2+, LTS 3.14.41+), pushed to the [core] repository in the past couple of weeks, were affected by a bug that can cause data corruption on file systems mounted with the discard option and residing on software RAID 0 arrays. The issue has been addressed in the linux 4.0.4-2 and linux-lts 3.14.43-2 updates. Due to the nature of the bug, however, it is likely that data corruption has already occurred on systems running the aforementioned kernels. It is strongly advised to verify the integrity of affected file systems using fsck and/or restore their data from known good backups. For further information please read the LKML post by Holger Kiehl, the related article on Phoronix, as well as the proposed fix that was backported to the Arch kernels." Am I correct to assume that this would ONLY affect systems that include a RAID-0 filesystem, and that it would not affect other ext4 systems using SSDs with "discard" in /etc/fstab?

[arch-general] Why is GCC 5 set to use the older C++98 libstdabi?
by Pouar 25 May '15

25 May '15

instead of the new one included with GCC 5? I'm just curious on why the gcc package maintainers chose this. -- Pouar
