The first statement I would agree on but in what way is Arch Linux with systemd a disaster? It runs very smoothely and fast over here. Or is it just the usual wannabe elitist bull...?

You know, the systemd (and friends) actually does a great job of ruining my day with Arch boxes - by now I have one permanently hanging on boot, another booting up twice as slowly as it did before the switch and a third one, which gets misconfigured by the boot-time voodoo. Sure, at least some of these problems are solvable, but I have to invest quite some time into it - and all of it goes into compensating the improvements in boot process. And I still can't see any benefit from the switch. -- Dmitrij D. Czarkoff

Czarkoff The problem I see here is that the big GNU+Linux-distributors tend to add more and more abstractation layers on top of the base-system to automate it. A good example is the Gnome NetworkManager, which actually writes a ton of Mac Addresses into /etc/conf.d/net, making it impossible to hand-maintain these things afterwards. I could go on with PAM, ConsoleKit, Gnome KeyringManager and the like, but I'm sure you know (better) of the metastases of this cancerous disease so many man-hours were wasted for and which is the reason why we need multi-million dollar companies behind the big, automated distributions to fix software which breaks due to that, in the interest of providing a consistent user experience. If you ever dare to dig deeper or if a problem surfaces, you're screwed. That's why I'm using Gentoo (On my Mac mini :P). Cheers FRIGN -- FRIGN d...@frign.de

For a data point, I haven't had the time to compile suckless in a while and never heard of these problems. Hunt that bug down, while I expect either it's somewhere in dwm or in x11 itself, I'll gladly follow your progress as a c programmer as well as with gdb. cheers! mar77i

It's: http://git.suckless.org/st/commit/?id=fbc589d50603e8b0de9239e4800e227ab5d0ea69 up until this commit st works fine for me. Does it continue to work if you go to git HEAD and revert that one commit? Because frankly I'd be really surprised if it did. All that commit does is shuffle around tty allocation a bit. I don't think the bug is in st. No X application should be able to freeze the X server and with it the machine. That's a bug in the server and/or the kernel you're using. One culprit could be the binary driver for your graphics hardware, but I'm not sure on that. I'd try running st with another driver for your graphics card and/or an older kernel version, and check if you recently upgraded your X server. If so, a downgrade could solve that problem, but reporting a bug with the proper authorities (i.e. either the kernel maintainers or the X.org guys) is a good idea nonetheless. -- Gregor Best -- Sturgeon's Law: 90% of everything is crud.
Re: [dev] [st] System freeze when killing X after using st-git (fixed)
Hello, I just cloned the latest git version and removed the commit manually from st.c and put the few deleted lines back in. Now st works just fine again. That's all I can say and I think that was pretty bad-ass of me given the fact that I can only do hello world in C :-) I'd say it's up to the developers if they want to leave this commit in or take it out like I did. I'm just glad I can use the latest version of st again. Andreas

Reverting a commit is very easy with git. In your case it's the simple matter of doing: $ git revert fbc589d50603e8b0de9239e4800e227ab5d0ea69 Now st works just fine again.

Just reverting that commit in the repository is not a proper solution to the problem. Some investigation has to happen. It's absolutely correct that it should not be possible to write an X application that can crash the X server, let alone the kernel. What graphics driver are you using? Since nobody else reported that bug, it really seems like the problem lies in the nature of your particular system. Kind regards, -Alex

Unfortunately it's not. I think I remember that this issue was reported here before. The problem is quite old. I have this problem on two different systems (my netbook and my desktop computer), so I think it is independent of the system. On both my systems I have ATI cards and 64bit Archlinux runs on both. I was just too lazy and stuck with the latest stable version of st, but honestly I'd much prefer to use st-git! pgphJgersSExp.pgp Description: PGP signature
