However, I haven't actually set that up myself. logind does that for you automagically™. The first seat has the rights to poweroff or reboot the machine, and it can differentiate between local and remote logins. You can check if your user session has the permissions to poweroff/reboot via dbus: $ gdbus call --system --dest org.freedesktop.login1 --object-path /org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanPowerOff ('yes',) $ gdbus call --system --dest org.freedesktop.login1 --object-path /org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanReboot ('yes',) But you need systemd to use logind1. There has been some attempts to reimplement logind outside systemd, but I'm not sure how advanced they are. This kind of problems were one of the reasons for creating logind. and dump people keep talking nonsencely that sysvinit is enough while it cannot even handle reboot for normal user. sad.

Use a file system that turns random writes into sequential writes, like the pretty newcomer f2fs. You could try using it for your rootfs but currently I suggest just creating a separate partition for it and either mount it as /usr/portage or symlink that dir into this directory (that way you could use it for other purposes, too, that generate random short writes, like log files). Then, I'd recommend changing your scheduler to deadline, bump up the io queue depth to a much higher value (echo -n 2048 /sys/block/sdX/queue/nr_requests) and then change the dirty io flusher to not run as early as it usually would (change vm.dirty_writeback_centisecs to 1500 and vm.dirty_expire_centisecs to 3000). That way the vfs layer has a chance to better coalesce multi-block writes into one batch write, and f2fs will take care of doing it in sequential order. I'd also suggest not to use the discard mount options and instead create a cronjob that runs fstrim on the SSD devices. But YMMV. As a safety measure, only ever partition and use only 70-80% of your SSD so it can reliably do its wear-leveling. It will improve lifetime and keep the performance up even with filled filesystems. -- many thanks to all of you! no I've put my portage tree on an F2FS partation now.

If you're building new, performance-oriented box, you should take latest intel with AVX because of AVX. As I recall, recent gcc has support for avx, so some performance gain may be achieved. If you want home box, you may be interested in AMD A8 and similar chips, as they are reasonably fast and very chip AMD parts have had AVX since the Bulldozer core release in Q3 2011. Are they already available in reasonable numbers on market? http://www.cpubenchmark.net/cpu.php?cpu=AMD+FX-8120+Eight-Core At $150, fitting into existing Socket AM3+ boards, that looks like the best part for my money right now. In any case, I'd put most of my money in 2-4 big 3Tb HDD's for media and 8+ Gb fast memory, as modern browsers eat memory like crazies and CPU is usually fast enough. Decoding HDTV mkv's should occur on gpu block in any case, so general performance for most uses is irrelevant, as it was fast enough four yesrs earlier. Simply check, that you can offload HDTV decoding to GPU in your config. Here, you're talking about either VDPAU or VAAAPI support. VDPAU is only offered by nVidia cards, and even then you need to run the proprietary driver. VAAPI is supported by Intel graphics and ATI's proprietary driver. I do not see any problems with this. A blob in system is not best practice, of course, but it does not need any configuration and is not a performance bottle-neck, so there is no reason to care. I only bring it up because some people do care. I'm running fglrx at home right now. When I run nVdia, I run the nVidia drivers. In part because I like accelerated video decoding (which a Geforce 210 does wonderfully), in part because the nv, nouveau and radeon drivers historically worked very poorly for me in 2D performance when faced with multiple 1080p displays. They're always getting better, of course. I personally would prefer AMD A8 if I can offload decoding to GPU unit there (not sure if I can, so won't change my box till next summer), but discrete video card will not be the most costly part in good non-gaming box, hard drives will, so again, what the matter? Computer usage breaks down into more than gaming and non-gaming. My non-gaming boxes at home tend to have their CPU, RAM or NICs as their most expensive components, because that's where I need them to perform better. -- :wq
Re: [gentoo-user] new machine : CPU : 22 nm vs 32 nm
2012/7/26 Philip Webb purs...@ca.inter.net: I've listed what's available at the local store, which I trust to stock reliable items, tho' I wouldn't ask their advice. All the AMD's are 32 nm , while the Intel recommended by one commenter -- Core i5-3570 4-Core Socket LGA1155, 3.4 Ghz, 6MB L3 Cache, 22 nm -- is 22 nm : it costs CAD 230 they have 3 in stock, which suggests demand, but not the most popular ( 9 in stock). Isn't 22 nm going to be faster than 32 nm ? In the same price range, AMD offers Bulldozer X8 FX-8150 (125W) 8-Core Socket AM3+, 3.6 GHz, 8Mb Cache, 32 nm ( CAD 220 , 2 in stock). How do you compare cores vs nm ? How far is cache size important ( 6 vs 8 MB )? cache size is always the most important thing. cache miss is the top reason your application slows down. When I built my current machine 2007, the CPU cost CAD 213 , so both look as if they're in the right ballpark. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

A quick look at what was available in April suggested an Intel Ivy Bridge i7 ( 22 nm ) ; Phoronix said it works with Kernel 3.2 + an Intel Z77 mobo (I usually buy ASUS) that power/watt was excellent. The best performance for money is the i5 2550K CPU. If you want the integrated graphics because you don't have an actual graphics card, you can go for the 2500K. For those don't want an integrated graphics, buy Xeon E3-123? serise CPU. the same price as i5 2500K , but you got 8 thread :) This is a Sandy Bridge CPU. I normally don't recommend the Ivy Bridge ones because they run hotter, so changing the clock multipliers isn't as fun as with Sandy Bridge.

So, the question now becomes: what's the drawback/benefit of NFS-sharing vs HTTP-sharing? The scenario is back-end LAN at the office, thus, a trusted network by definition. NFS doesn't like when it looses connection to the server. The only problems I had ever with NFS were because I forgot to unmout it before a server restart or when I took a computer (laptop) off to another network... NFS-shares can work, but these need to be umounted before network goes. If server goes, problems can occur there as well. But that is true with any server/client filesharing. (CIFS/Samba, for instance) Otherwise it works well, esp. when mounted ro on the clients, however for distfiles it might make sense to allow the clients download and save tarballs that are not there yet ;), though I never used it with many computer emerging/downloading same same stuff, so can't say if locking etc works correctly... Locking works correctly, have had 5 machines share the same NFS-shared distfiles and all downloading the source-files. And with NFS the clients won't duplicate the files in their own distfiles directories ;) Big plus, for me :) -- Joost signature.asc Description: OpenPGP digital signature
Re: [gentoo-user] UEFI specification
2011/11/12 James wirel...@tampabay.rr.com: Here is a quick description of how Redmond intends to taint the bios on new products: http://www.linuxjournal.com/content/linux-heavyweights-develop-secure-boot-strategy So, recently I took a live-dvd-11.2 into Costco to check out a new HP laptop (DV7-6178US). It would not boot the DVD. How can I research if the UEFI bios is the issue? In the past the live gentoo dvds have booted up most every (new) laptop I have tested. Sure I can purchase the laptop, bring it home and hack on it, but, it would be much more straight forward if there was a list of UEFI infected computers somewhere. (any lists?) I do not want to waste my time on a laptop that has this MS tainted bios. Methods and ideas to flush this out, before purchase are most welcome? Is it possible that some windows 7 laptops have the UEFI bios? UEFI only boots 64bit OS. 32bit OS should be loaded via BIOS emulation mode. So, if the pre-installed windows is 32bit. the UEFI must not be tainted. I usually prefer a dual boot laptop, with doz and gentoo, but that looks like a fading option these days.? James
