[arch-general] libssh: 0.7.5 from AUR seems to have config reading issues
by Artyom Poptsov 06 Aug '18

06 Aug '18

Hello, it seems that AUR provides libssh version 0.7.5 that has some issues with SSH config reading (it fails to read options from a provided configuration file.) Back in June 2017 I prepared a patch to fix the problem: https://git.libssh.org/projects/libssh.git/commit/?id=5333be5988c3789e70115… but the patch was integrated to libssh _after_ 0.7.5 release (it was released in April 2017.) Could the libssh library be upgraded in AUR to integrate the aforementioned patch? I'm not an avid Arch GNU/Linux user so if I'm wrong about something please don't hesistate to point me out to it. FWIW, I'm the main developer of Guile-SSH library [1] that uses libssh. Thanks! - Artyom [1] https://aur.archlinux.org/packages/guile-ssh/ -- Artyom V.

[arch-general] How to make aura more verbose?
by Peter Nabbefeld 03 Aug '18

03 Aug '18

Hello, trying to use aura instead of pacaur. Yesterday I started to install jitsi - it's still running (?). Well, it's also the first time I'm installing this package, so I don't know how much effort is needed for building. However, I'd like to see all the messages like with pacaur, but aura keeps to be silent, even with the -v option. :-/ How can I switch the messages on? And are there any build logs I can watch? I'd prefer not to stop a build which is running several hours before making sure it really hangs. Kind regards Peter

[arch-general] xrandr with XPS 13" (3840x2160) HiDPI and 30" (2560x1600) LowDPI
by Tyler 02 Aug '18

02 Aug '18

Hi, I am using ArchLinux with i3 on my Dell XPS 13" 9370 @ 3840x2160) HiDPI and everything works great with: .Xresources: ! xft fonts !---------------------------------------------------------------------- Xft.dpi: 220 Xft.autohint: 0 Xft.lcdfilter: lcddefault Xft.hintstyle: hintfull Xft.hinting: 1 Xft.antialias: 1 Xft.rgba: rgb ! urxvt !--------------------------------------------------------------------- URxvt*font: xft:DejaVu Sans Mono for Powerline:size=12: \ minspace=False:antialias=true, \ xft:Segoe UI Emoji:size=12:minspace=False:antialias=true URxvt*boldFont: xft:DejaVu Sans Mono for Powerline:size=12: \ minspace=False:antialias=true, \ xft:Segoe UI Emoji:size=12:minspace=False:antialias=true URxvt.letterSpace: -1 and in /etc/profile.d/hidpi.sh export GDK_SCALE=2 export GDK_DPI_SCALE=0.5 export QT_AUTO_SCREEN_SCALE_FACTOR=0 export QT_SCREEN_SCALE_FACTORS=2 export QT_QPA_PLATFORMTHEME=qt5ct However recently I bought a Dell DA300 Mobile Adapter and decided I wanted to use my external Dell 30" 3000WFP (2560x1600) over DisplayPort. I found this blog article https://blog.summercat.com/configuring-mixed-dpi-monitors-with-xrandr.html which explains exactly what I am trying to do. The only difference is the placement of the external screen (mine is on the left of the laptop) and the screen size and resolution. In that article he uses his HiDPI on both screens and then scales down on the external screen, which is why he doubles the resolution of the external display. The reason he does that is so he doesn't have to touch .Xresources or fiddle with toolkit scaling options. Using this command I was able to get it working great with a single external monitor ie the Dell 30" 3000WFP @ (2560x1600) xrandr --dpi 220 --fb 5120x3200 \ --output eDP1 --off \ --output DP1 --scale 2x2 --panning 5120x3200 With the dual-monitor setup I'm struggling to understand the panning option. I have looked at https://wiki.archlinux.org/index.php/xrandr and the man file and still couldn't figure that track x track y part out. It's not very easy to understand. So far for the external monitor I have this: xrandr --dpi 220 --fb 8960x5360 \ --output eDP1 --mode 3840x2160 \ --output DP1 --scale 2x2 --pos -2560x0 --panning 5120x3200+2560+0 What I want is to be able to access the whole area of both screens. In his example he has a laptop at 3200x1800 and an external monitor at 1920x1080 > Dual monitors > > When I want to use both monitors, this is the command I run: > > xrandr --dpi 276 --fb 7040x3960 \ > --output eDP-1 --mode 3200x1800 \ > --output DP-1-2 --scale 2x2 --pos 3200x0 --panning 3840x2160+3200+0 > > Here's an explanation of the options: > > Global options: > --dpi 276 sets the DPI to 276. > --fb 7040x3960 creates one screen with resolution 7040x3960. This is the combined resolution of the two monitors. The high DPI monitor has 3200x1800 resolution. The lower DPI monitor has 1920x1080 resolution, but I double it as I scale it by 2 (see below). Combine these like so: 3200+1920*2 x 1800+1080*2 = 7040x3960. Both monitors share this screen. > High DPI monitor options (--output eDP-1): > --mode 3200x1800 says to use resolution 3200x1800. This is the default, but specifying it is necessary if the monitor is disabled (as it is when using the external monitor by itself) as it enables the monitor. > Lower DPI monitor options (--output DP-1-2): > --scale 2x2 is similar to zooming out. This is necessary as we set the DPI globally to that of the high DPI monitor. > --pos positions it to the right of the laptop monitor. > --panning allows our pointer to access the whole area. Any help or tips would be much appreciated! -- Tyler

[arch-general] systemd --user enable: Failed to connect to bus: No such file or directory
by Bjoern Franke 01 Aug '18

01 Aug '18

Hi, I'm trying to create a systemd timer for a user to run duply daily. For one user the enabled worked fine, but another one: systemctl --user enable backup.timer Failed to connect to bus: No such file or directory I have no clue why this happens, systemctl daemon-reload (also with --user) did not fix it. I found a similar issue in the forums, but the solution was to "ln -s" the timer and than rebooting. But I don't think this would be the "correct" solution because "systemctl --user enable" should also work. Any hints? TIA Bjoern

Re: [arch-general] Kernel modules not loaded after Linux update

It looks like the problem is that the /boot partition was not mounted, as it usually is, during the update process. This caused the previously installed kernel to load, and the modules to fail to load due to version mismatch. I fixed it by booting to live media, mounting the /boot and / partitions appropriately and doing arch-chroot to / to install the cached 4.17.10 image with pacman -U For now I've also put the /boot partition in my fstab, even though iirc the wiki recommends against this. Good luck, -Shawn

[arch-general] Arch Linux PC as a Remote Desktop Node
by Foxtrot Mike 30 Jul '18

30 Jul '18

Hi all, Currently we have around 10 employees who develop software using Visual Studio. The idea is to install the development tools on the Windows Server system, and to have all the developers connect to the server over RDP using low-end low-power computers. The server is pretty beefy though. The low end client PCs will save up-front cost as well as power bills. The network backend will not have any issue with the increased RDP traffic. I have been using Arch Linux for some years now, so I undertook this as a research project. I want to use the Arch system as a Remote Desktop node. The Arch system would use a login manager (such as lightdm) to authenticate users from Windows Domain. Once the user has been authenticated, the system is supposed to automatically open a RDP connection (using freerdp) to the Windows Server (if possible, using the credentials provided to lightdm so the user doesn't have to enter his password twice). As soon as the user quits the RDP session, his X-session should also be closed automatically. Here are the major tasks: 1- Ask LightDM to use Windows Domain (Kerberos) authentication. I am a little confused. There are supposedly many different ways with little changes to do this. [1] is one solution. LDAP is also a possibility. I need advice from someone who knows this field better than me :p 2- How to ask i3-wm (my default wm) to run freerdp at login? I guess [2] will get this done. 3- How to ask freerdp to authenticate using the ticket received from TGT during LightDM Domain authentication? If I could somehow configure freerdp to use Kerberos Tickets then the user won't have to enter his Domain password again. 4- How to ask i3-wm to close the X-session when freeRDP quits? I read something a while ago about .xsession files to achieve this functionality, but can't find it now. Any help would be appreciated! Regards.
