[arch-general] qt5ct color scheme -> looking for a lxqt dark theme
by Javier 26 Sep '17

26 Sep '17

Hi, I've been looking for getting a dark appearance to lxqt, and so far the closest is through qt5ct color schemes specified through *.conf little files under qt5ct, somehow documented here: [1] https://www.pcsuggest.com/lxqt-dark-style When using the breeze color scheme provided by [1]: ++++ [ColorScheme] active_colors=#eff0f1, #31363b, #4c545c, #40464d, #171a1c, #2a2e32, #eff0f1, #ffffff, #eff0f1, #232629, #31363b, #111314, #3daee9, #eff0f1, #2980b9, #7f8c8d, #31363b, #000000, #31363b, #eff0f1 disabled_colors=#6e7175, #2e3338, #4a5259, #3e444a, #16191b, #282c30, #65686a, #ffffff, #6e7175, #212427, #2e3338, #101213, #2e3338, #6e7175, #234257, #404648, #2e3338, #000000, #31363b, #eff0f1 inactive_colors=#eff0f1, #31363b, #4c545c, #40464d, #171a1c, #2a2e32, #eff0f1, #ffffff, #eff0f1, #232629, #31363b, #111314, #224e65, #eff0f1, #2980b9, #7f8c8d, #31363b, #000000, #31363b, #eff0f1 ++++ There's no contrast at all between active and non active tabs on multi-tab applications, pretty noticeable in qt5ct itself and qterminal... Is there a way to get such color scheme files to choose from? Also, is there some specification of what each of the 20 colors specified per active/disabled/inactive ones is supposed to mean? The inactive and active ones are pretty similar, except for the 13th color, not sure if some more should change. The disabled one is of course more different, :) I'm not looking for the inactive colors to be similar to the disabled ones, just a bit more of contrast than what I see, which is no difference on tabs or even buttons... Thanks, -- Javier

[arch-general] gscan2pdf - could it be included in the official arch repositories?
by Stephan Fuchs 26 Sep '17

26 Sep '17

Hello! I would like to ask if the program gscan2pdf could be included in the official arch repositories. In particular also for all necessary perl dependencies to work For me and many other people it is a very important office program. (179 votes) With it we can scan all letters and documents easily for archiving with gscan2pdf. In the AUR, there have been some problems since the packages are outdated. And since I regard as important, I want to ask if it is feasibl to included gscan2pdf in the official repositories. There are currently no alternatives. best regards Stephan Fuchs

[arch-general] tmux/systemd: tmux user service exits on detach/logout
by David Runge 25 Sep '17

25 Sep '17

Hey all, I got a very strange behavior with tmux and systemd on my server and maybe someone knows a way around it. The way I start tmux is as follows: Setting TMUX_TMPDIR to my user's XDG_RUNTIME_DIR and starting tmux in a systemd user service [1]. I do the same for other things, such as weechat [2]. They both use the same tmux.conf [3]. Lingering is activated for my user, so the enabled user services will start with the system and stay running, even when it's disconnected... in theory (and this used to work very well, without a problem for years). With some changes in systemd however, this seems to fail now, and I can't seem to find the reason why. Tmux just exits with "server lost" once I do a detach. At first I could only observe this behavior when I had a shared ssh session to the server (so I thought), that I then quit, or when I attached and detached the tmux session quickly. Now I'm getting this nearly every time I detach from the tmux session! I tried several things by now, and it doesn't seem to make any difference: - using legacy cgroups [4], because of maybe being affected by this [5] - switching to single connections instead of shared connections for ssh (lowered the amount of random tmux quits!) - using hardened kernel (just to try another one) - logging a tmux session, without getting any output, that would explain, why this happens - crossing fingers (actually helps, because the bug seems completely random ;/ ) - using a system scope unit (tmux@username) [6], getting the same results - downgrading tmux to >=2.3 (no difference) - downgrading systemd to <=233-7 (seems to happen less frequently) For some awkward reason, it seems to have worked again for a short time, when Arch first switched to systemd 233 a few days back [6], but ever since it moved to systemd-stable [7], the problem is back (and even worse than before). Me thinking that might only be due to a "less frequent occurence" though. I'm just wondering, how to solve this. Maybe someone has a great idea to share? It's getting beyond annoying by now and I can't seem to find out, if it's tmux, systemd or some kernel problem... or all of them together. David P.S.: Doesn't seem to happen with screen. I don't want to adapt everything to screen now though ;) [1] https://git.sleepmap.de/software/uenv.git/tree/user/tmux.service [2] https://git.sleepmap.de/software/uenv.git/tree/user/weechat.service [3] https://git.sleepmap.de/config/dotfiles.git/tree/.tmux.conf [4] https://www.freedesktop.org/software/systemd/man/systemd.html#systemd.legac… [5] https://github.com/systemd/systemd/issues/3388 [6] https://wiki.archlinux.org/index.php/Tmux#Autostart_with_systemd [7] https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/sys… [8] https://github.com/systemd/systemd-stable -- https://sleepmap.de

[arch-general] [Classroom] pre-announcement and poll for Python for Beginners
by fsckd 24 Sep '17

24 Sep '17

Hello, If you are interested in learning the basics of Python and are confused where to start or you know someone that could use Python in their work or hobbies, there is an upcoming class. Notes are available online.[1] There will be 5 or so sessions, each lasting 2 hours, to be held on different days. The format is similar to past classes[2] and this class will be held on IRC with logs published afterwards. New for Classroom, this class will have a simultaneous live stream accessed through YouTube which will be later saved and archived (with subtitles). As attendants could be from different time zones, there will be a poll to schedule each session. Links for first 2: https://framadate.org/archpyb-poll-1 https://framadate.org/archpyb-poll-2 To vote, use the password: archclass Your vote is not publicly visible. Note that times are in UTC (and the times listed in both session polls overlap). The 2 hour window with the most votes will be announced officially here on arch-general and other venues like the BBS.

Re: [arch-general] systemd - move to base group and expect it to be installed?
by Marc Boocha 20 Sep '17

20 Sep '17

I am unable to send to arch-dev-public for some reason so i am send my reply to arch general. I think the filesystem can be split, the sysuser/tempfile will be in the independent package. I do believe we seriously need a meta package for some parts of base. Systemd, Glibc, PAM, Filesystem, Coreutils, mkinitcpio ,Util linux and linux firmware are obviously need to be moved to a metapackage. This helps since it makes it easier during major transitions in the future. Stuff like editors, bootladers, kernels (efi partions when dual booting has space for a single kernel), snail are optional and remain as a group. The meta package takes place of all other package of the base group.

[arch-general] Ardour 5.11
by David Runge 19 Sep '17

19 Sep '17

Hey Ray (and all interested), thought I'd share an updated PKGBUILD for Ardour. Please update to the latest version! 5.9 is unusable, when working with OSC to control it (segfaults). I know there is some AUR package, but ardour 5.11 is a stable release and should therefore be in the main repos. Best, David -- https://sleepmap.de

[arch-general] gnome fix needed
by Jude DaShiell 14 Sep '17

14 Sep '17

I discovered this and was able to recover, and think gnome could do with a fix. I put together a script to completely erase gnome from this system and for the most part that script worked really well. The exception was that it also removed wpa_supplicant since I had cascading and recursive and unneeded packages being removed. Without wpa_supplicant on a system that system in command line mode isn't getting out onto the internet. I put wpa_supplicant back on the system using the install disk I have and the internet at least is working correctly. I was trying to get orca talking on the system and couldn't do it so figured it's best if I start with a clean slate which is the reason for the removal script. I'll run it for xorg and mate before I'm finished and try to get all of this stuff running again without questionable configuration files on the system. I think I may get lucky. According to email from another list, apparently neither gdm nor lightdm will get us screen reader users to a talking orca, but xorg should get that job done. If someone has the time, please run sudo -H Xorg --configure and let me know if that command errors out with a segmentation fault at address 0x50 or any other address or if you get a configuration file generated. It could be xorg configuration on this system is also messed up beyond repair and I'll have to clean that out too. --

[arch-general] Detect broken DHCP setup
by Giovanni Santini 08 Sep '17

08 Sep '17

Good morning, tl;dr: I was wondering what could be the best way to check a DHCP setup. Briefly: our landlord provides us Wifi through a telephonic company service. However, the routers placed in the building after some time lose the DHCP settings. While I can fix it on my computer with a reconnection, such a method is not applicable to my Raspberrys. On one I have Raspbian, on the other ArchLinuxARM. While I found a possible solution for the Raspbian, for ALARM I have some doubt. On that device I am using *systemd-networkd + systemd-resolved* for the network setup. However, I saw no real method to check if the DHCP configuration is valid (while NetworkManager provides an element through DBus inspection). Does anyone has some knowledge about it? To be fair, I am asking as I am sure the 'ping Google DNSs and if it is screwed restart the networking, use this as a cron job' will likely work, but I was interested in a more elegant way to approach it (like the NetworkManaged DBus introspection). Thanks in advance to all! -- Giovanni Santini My blog: http://giovannisantini.tk My code: https://git{hub,lab}.com/ItachiSan My GPG: 2FADEBF5

[arch-general] Possible error while refreshing pacman keys
by Arch User 08 Sep '17

08 Sep '17

Running either of the commands 'pacman-key --populate archlinux' or 'pacman-key --refresh-keys', outputs 'signature(s) not checked due to a missing key(s)'. Performed a fresh install today with the latest iso and the error stays. Checked and confirmed that all the 6 master keys and their signing keys were already added.
