Re: Can't boot Nov 21 amd64/bsd.rd - finishes at 'entry point'...
I was experimenting the same behaviour in my T410. With recent snapshots (november) or building a new GENERIC.MP kernel after update from CVS, the system freezes just when the boot process starts. I can confirm that the system boots normally after activate NX. In my thinkpad's bios the NX is located at: Security / Memory Protection / Execution Prevent I don't know if this behaviour is intentionally or a bug. In 5.6 stable the system boots though NX is deactivated. I must say too that the system is much more stable doing suspend/resume. With 5.6 stable the system tends to hang on resume. But with current suspend/resume works perfect. BR Jes
5.5 current resume hangs
From at least a couple of month my laptop doesn't resume after suspend. Mine is a thinkpad T410 with intel integrated gpu. The behaviour seems to be the same as reported in: http://openbsd.7691.n7.nabble.com/T410i-resume-broken-with-amd64-bsd-mp-and-revision-1-249-of-acpi-c-td240150.html But, I think in december 2013 my laptop was able to resume with current. With the SP kernel the system suspends and resumes perfectly. I didn't see any other report besides the previous one about this issue. Thanks in advance, Jes

Re: Failed to hibernate in 5.4 current i386
Sorry, I don't understand you. You says the problem is solved since yesterday (the snapshot my computer is running is from 03/11/2013), but at the same time you says the swap size is not bib enough, but it's more than the memory+64Mb (http://undeadly.org/cgi?action=articlesid=20120712101743). And, in fact, my laptop hibernated one week ago (more or less). I have two swap partitions, sd1b and sd1j. The total amount of swap is about 12G. I think with the small one (more than 3Gb) the system hibernated, and with the 8Gb it did too. Could you explain a bit more this?

Next, check if the range consuming the last physical memory size amount of swap was unallocated (eg, on an 8GB machine, check to make sure that the last 8GB was unallocated). If not, abort hibernate. You probably had something swapped out into that end range, so we aborted. But as Theo mentions, this discussion is moot due to the improvements that went in yesterday.

Re: Feedback about Desktop Environments
Regarding samba... there's no need to automount samba folders because you always can browse them via file browser (konqueror, thunar or nautilus), but if you want you can mount them in /etc/fstab. Simply read the documentation about permissions and syntax. It's very easy. For NFS the best way is mount them in /etc/fstab too. For external disks/pen drive, hotplug-diskmount, as Marc said, it's the best option. This pretty tool automount the drives when inserted and unmount when the drive is plugged off. If the drive is FAT you can extract it before unmount it. For other systems different from FAT you must unmount before extract.

Re: Feedback about Desktop Environments
Hi all: I use during so long time KDE3. Nowdays I prefer xfce4. Gnome3 is a bit ugly for me. I prefer WMs that integrate the file browser and other tools. Because of this I don't use WindowMaker or FVWM or Enlightenment If I'd only had to code I'll use vim and some minimalistic wm. In my experience, KDE3, Gnome3 and XFCE4 are good choices for general use. Not related with the desktop choice but with the performance... In OpenBSD, all versions, I note performance decrease (not smooth mouse movement or web page scrolling) when the machine is doing any heavy reading/writing task or cpu compsuming (for example a rsync or zip/unzip a big file). Has anyone else experienced a similar behaviour?

Does KDE3 work well on OpenBSD? Things like k3b and similar apps that come with it or, is XFCE more likely to have better support for graphical apps to play CD/DVD's, burning media, music, stuff like that. That is what my partner will want to use. I can do the configuration, where necessary, but don't want to be constantly hassled into showing how to use stuff.

Always when a lot of readings/writings are taking place in the disk, or for example, when the CPU load is high though in a only core. My machine is not very old; it's a thinkpad T410 with 4 cores and 8MB RAM (amd64). If only one core is on high CPU I experienced a not so smooth scrolling in firefox, or the mouse pointer jumps from one place to another one when moving. I didn't experience this in linux or freebsd... And it ocurrs in 4.9, 5.0... and 5.4 current. Back to the desktop environments... KDE includes some tools for administration (users, permisions, etc.). Konqueror file browser is a bit old and has some bug (for example moving files, cut/paste) but it works well in general. If you want to more integrated desktop with its file editor, file browser, clipboard tool, display tool (for screen resize), burn cds, etc. KDE is a good candidate. Gnome3 is more modern than KDE, if it fits your needs in terms of functionality and you like its appearance then probably it works in a better way than KDE. If you need something simply, but functional, with a small application tools for thinks like file browser, image viewer, simple edition, clipboard management, folders in desktop, panels for quick launch, etc. XFCE would be a good option. Maybe it's a question of install the three and test them. For coding or administration only, probably wms like ratpoison, xmonad, and so would be the right election, in terms or reduced CPU and memory consumption. BR
Re: Changing Architecture from amd64 to i386
In my experience it's perfectly possible to move from one architecture to another one. I do the following: - backup /etc (only for security) - remove all installed packages (I save a list of installed packages to figure out what to install again after) - sysmerge for etc and xetc - update the system with the new architecture (update, not install) - adjust $PKG_PATH and reinstall packages deinstalled at the beginning, or new ones of your election. No major problems detected.

Re: Downlink speed limit
Solved. There's no problem with my laptop or nics. It's a problem of the web speedof.me. For some reason, this web does not measure in the same way in linux than in OpenBSD.

Downlink speed limit
Hi all: I'm running current amd64. I've detected a problem with the network speed. My internet connection is cable, with 20Mbps. In Linux, with several speed meters (my provider's and, for example, speedof.me) I always get around 20Mpbs in donwlink, and about 2-2.5 Mbps in uplink. But with OpenBSD current there is a limit around 4Mbps in downlink (uplink is ok). It doesn't matter if the PF is enabled or disable, the speed is always ~4Mbps. Ethernet card is in 100Mbps full-duplex. I've google a lot and tried several sysctl tweaks but without success. Right now I've finished to upgrade to the last snapshot and the problem remains.

NFS and mounted dirs by hotplug-diskmount
Hi all: I have one computer acting as NFS server for some directories. One of these directories is /vol, where the hotplug-diskmount daemon mounts external disks (usually FAT32). The problem is that whereas NFS is working well (rest of dirs are available through my local network) those mounted by hotplug-diskmount are missing. I can't see any of this dirs. If I export these dirs in /etc/exports for NFS, then I see this dirs but no content is shown inside them. Any idea about this? I suspect it's something related to the hotplug-diskmount internals but maybe there's a solution... Thanks in advance, Jes

Re: Idea for apmd
I agree with Juan Francisco, In think it would nice to have a more smoth speed control cpu way, forma example like the proposed oneroso in this thread, similar to netbsd. Andris it would nicer if in a future openbsd implementar the P-states oferta the cpu, to save battery on laptops. Anyway my openbsd laptop (thinkpad R61 2200 Mhz ) has a good performance with apmd -C. BR Jes (from Corunha :) ) El 30/05/2012 20:50, Juan Francisco Cantero Hurtado i...@juanfra.info escribis: Hi. I've been using OpenBSD on my netbook daily for a few months. I was using apmd with the -C setting. My netbook is slow and the battery life is important, so 800Mhz (apmd -C) or 1600Mhz (apm -A) is not a big difference for me. Now I have a desktop computer with support for cpu speed scaling. In this case the options of apmd are very limited. If I use -A my cpu is always at 2700Mhz, wasting energy and heating my room (I live in the very sunny Extremadura :) ). If I use -C, apm rarely raises the speed and the cpu is almost always at 800Mhz. This is important because when I open a web page with a lot of javascript, the browser is very slow. Also when I compile something with make -j1, apmd doesn't raise the speed of my CPU, I need use make -j4 for raising the cpu speed to 2700Mhz. I understand the problem with the limits of apmd. The developers can't generate a limits for each CPU and workflow. I've been playing with the values of PERFINCTHRES and PERFDECTHRES on usr.sbin/apmd/apmd.c and checking the changes of speed with while true; do apm | grep cool; sleep 1; done. I'm using 20 and 60 respectively right now. Probably this values aren't the best values but are better than the defaults (for my CPU and workflow). The performance is very good and I can see the cpu speed raising and lowering. I've tested various values and 20/60 are a good compromise performance vs energy consumption. In short, I have a suggestion for apmd. Add one option for to set PERFINCTHRES and other for to set PERFDECTHRES. Each user could to configure the behavior of apm -C on rc.conf.local. Example: apmd_flags=-C -I 20 -D 60. Obviously, apm -C would use the defaults if both options aren't used. The implementation is simple and it will not break any system. Unfortunately I can't code the idea (despite I've read the code), so I wanted share this with you. Some developer interested? :) Cheers. -- Juan Francisco Cantero Hurtado http://juanfra.info
