[arch-general] arch wiki xen installation questions
by John Davis 09 Oct '13

09 Oct '13

Hello I am trying to install xen. I am using this page as a guide: https://wiki.archlinux.org/index.php/Xen I have a problem where I can not get the commands for setting up the networking bridge to work. During the xen installation, I noted that it uses netctl instead of netcfg. I made those changes and if I boot my regular kernel it appears to work with a wifi connection. Here is the result of some command regarding networking with regular kernel. [root@t61p ~]# netctl list xenbridge-dhcp * wlan0-hs-dlink wlan0-hs-dlink.wifi-menu [root@t61p ~]# I believe this command shows that wlan0-hs-dlink is the active profile and is enabled at boot automatically. For instance: [root@t61p ~]# systemctl | grep hs-dlink netctl(a)wlan0\x2dhs\x2ddlink.service loaded active exited Networking for netctl profile wlan0-hs-dlink [root@t61p ~]# This is a result of systemd having netctl(a)wlan0\x2dhs\x2ddlink.service in the /etc/systemd/system/multi-user.target.wants directory. So it looks ok for having networking via wifi working in regular linux kernel. As far as xen and bridge goes, I created the following file /etc/netctl/xenbridge-dhcp with the following contents: Description="Xen Bridge connection" Interface=xenbr0 Connection=bridge BindsToInterfaces=(wlan0 wlan1 tap0) IP=dhcp Basically, I used the example given on the arch xen wiki page and changed eth0 to wlan0 and eth1 to wlan1. When I try to start the xenbr0 (bridge) I get an error about tap0 not found. This is the command I issue (bascially from the wiki) and the result from journalctl # netctl start xenbridge-dhcp -- Unit netctl(a)xenbridge\x2ddhcp.service has begun starting up.

[arch-general] Black screen at first boot
by Thorsten Jolitz 04 Oct '13

04 Oct '13

Hi List, since a few days (I did not change anything, no updates, nothing) the first boot of my machine results in a non-responsive black screen. I have to do a cold-start, and then the second boot works as expected. Has anybody witnessed this too? A hardware problem? -- cheers, Thorsten

[arch-general] Way too much kworkers
by Dimitris Zervas 02 Oct '13

02 Oct '13

Hello, I've googled a bit and saw that other people have this problem too, but without solution. They had maybe 8 or 10 kworker processes. After 2 suspends, I have 172. ps -ef | grep kworker | wc -l 173 (one of the line is grep's process). Is there any solution?

Why not use one branch per package and one branch per repository with the packages as submodules instead of a repository for each package? This way all the packages would be in a single repository and could be fetched all at once or one at a time.

[arch-general] xdm and awesomewm incompatibilty
by ashwin 30 Sep '13

30 Sep '13

Hi, I see that xdm and awesome wm dont go well together. It used to work well before. I see after recent package update. awesome wm crashes often. After killing xdm, it is back normal again. Has anyone else experienced this ? If xdm is buggy, then can someone suggest a good login manager for X ? I see gdm brings in gnome-shell and loads of other packages which is not directly related to login manager. What i am looking for is just the login manager and its dependecies and not the entire DE. I assume kdm does the same thing. The awesome wm & xdm version in my pc is: awesome 3.5.1-3 xorg-xdm 1.1.11-4 with regards, ashwin

[arch-general] Upgrade problem
by Phil Dobbin 30 Sep '13

30 Sep '13

Hi, all. I'm a newcomer to Arch Linux so excuse my ignorance. I attempted to update yesterday (pacman -Syu) & I got this message at the end of the update: '(121/121) checking for file conflicts [#################################################] 100% error: failed to commit transaction (conflicting files) filesystem: /bin exists in filesystem filesystem: /sbin exists in filesystem filesystem: /usr/sbin exists in filesystem Errors occurred, no packages were upgraded.' Can anybody tell me what it means & how to go about fixing it (I've got Arch running on a VPS). Many thanks, Cheers, Phil... -- currently (ab)using Arch Linux, CentOS 5.9 & 6.4, Debian Squeeze & Wheezy, Fedora Spherical & That Damn Cat, Lubuntu 12.10, OS X Snow Leopard & Tiger, Ubuntu Quantal, Raring & Saucy GnuGPG Key : http://phildobbin.org/publickey.asc

It seems that something has gone wrong with the drivers, because I get a result that I need to get information from a log file. Ok, so far so good. Startx is fairly simple, but can be confusing. I'm not that familiar with gnome, but which command starts it? Could you post the contents of $home/.xinitrc ? mvg, Guus

[arch-general] Fwd: Proposal for the static library problem in Arch
by Delcypher 30 Sep '13

30 Sep '13

Hi, Apparently I cannot post to arch-dev-public so I'm posting this here. This is a proposal for making separate packages for static libraries (with a patch for Boost C++ libraries as an example). Please see below... ---------- Forwarded message ---------- From: Daniel Liew <daniel.liew(a)imperial.ac.uk> Date: 28 September 2013 14:58 Subject: Proposal for the static library problem in Arch To: arch-dev-public(a)archlinux.org Hi All, I've noticed recently that there have been problems with static libraries being removed from packages. E.g. https://bugs.archlinux.org/task/35257 https://bugs.archlinux.org/task/34491 https://mailman.archlinux.org/pipermail/arch-general/2010-September/016152.… https://mailman.archlinux.org/pipermail/arch-dev-public/2013-March/024552.h… I've only just joined to mailing list so I couldn't find a way to reply to the emails I have never received so I thought I'd just start a new thread (apologies). I see both sides of the argument as valid: - Lots of people don't need the static libraries so why include them in packages, they are wasting space. On the other hand... - Some developers need static libraries to build their projects. In my case I needed to build a static library that has dependencies on the Boost library. I do not want unresolved symbols to Boost C++ library functions in there. I really don't think that completely removing static libraries from the repositories is the correct approach because it I believe the choice of whether or not to have static libraries on your system should be down to the user and not the distro (yes I'm aware I could compile boost myself... that's what I'm doing right now but what happened to "Keep it Simple"? If I wanted to compile loads of stuff from scratch I'd be using Gentoo). So my proposal is this: For popular packages that have can build static libraries and shared libraries, build both but put the static libraries into their own "*-staticlibs" package and the *-libs" packages should contain only shared libraries. For example for boost you would have boost : Development headers + other files boost-libs : Boost shared libraries boost-static-libs : Boost static libraries The boost package dependencies would be set to be dependent on boost-libs but **not** boost-staticlibs so the static libraries would only be installed if the user explicitly installed them. So everybody wins. Static libraries are not installed by default saving disk space but the static libraries are available as packages should the user decide they need them. Looking at the PKGBUILD syntax this looked quite trivial to do so I've done it for Boost and the patch is attached (apply against boost 1.54.0-3 PKGBUILD) Thoughts? Thanks, Dan Liew
