Re: [gentoo-user] HDD with too aggressive power management

However, now comes the problem: It seems that whenever I change from

after only a few seconds of inactivity. That sucks.
frustrating indeed! It could be a number of things: gnome, acpi, and/or
bios making the changes automatically.
My preference would be to fix it in acpid since it will work independent
of the window manager or even X.
emerge acpid, then edit /etc/acpi/default.sh similarly (sorry about the
tabs/spaces):

Change (or add) your hdparm commands as required. You could have a
different spin-down setting for power and battery if you wish.
You'll still have to change the setting after booting, since acpi events
usually aren't triggered then. Use local_start() as Paul suggested. If
you suspend you may even have to do it after resuming as well. Note
that if you use different spin down times you'll need to detect the
state of AC before running the hdparm command. Something like this
in /usr/local/bin/ should do:
#!/bin/sh
if ( awk '{print $2}' /proc/acpi/ac_adapter/AC/state | grep on-line ); then
# AC adaptor is on-line!
echo performance /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo performance /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
else
# AC adaptor is off-line!
echo conservative /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo conservative /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
fi
then call that script from local_start().

[gentoo-user] [OT] quad vga - dual or single card?
Hi all, I'm appealing to your collective knowledge for something not really gentoo :) I'm looking at 4 independent VGA outputs for a church media / stage environment (dvds, videos, presentations, maybe some live camera backgrounds under text such). Do you think it would be better to get either: * Dual 256MB PCIe x16 nVidia NVS 295, or * Single 512MB PCIe x16 nVidia NVS 420 The single NVS 420 is about $350 more than the dual 295. (There is a dual 420 option but that's another $1000 so I'm hoping to avoid it!) both are quad-monitor capable. I'm considering performance, heat, power, noise, and anything else you can think of. The 295 is passively cooled, 23W each, whereas the 420 is active cooled but only 40W, or so they say! any tips much appreciated :) -- Iain Buchanan iaindb at netspace dot net dot au If you're not part of the solution, you're part of the precipitate.

S4 writes a bunch of stuff to disks and then powers down just like a normal shut down (S5). You can even take out the battery (I even stripped an old laptop, removed the cpu, disks, heat pipes, fans, and put it all back together on S4 and then resumed). S4 can leave some bios function and power for WOL and other devices, but it's not essential.

Re: [gentoo-user] Laptop
Hi, Ask not will this work on Gentoo, rather ask will this work on Linux! You'll get much better responses to your research on google at least. If it works on any mainstream Linux distribution, there's a 99.9% chance it will work on Gentoo. For example, I just did a google search for NVIDIA® GeForce® GT 425M linux and found out in a few seconds that it probably works with nvidia-drivers 260.19.06, but not nouveau (open source drivers). http://packages.gentoo.org/package/x11-drivers/nvidia-drivers tells me that nvidia-drivers 260.19.06 and 260.19.12 are hard-masked because they're in the beta phase, so you may or may not have success with them. You can repeat that search (hardware-device linux) for all the usual problematic hardware that you decide you must have working: * video camera * wireless * ethernet * bluetooth * audio however you need the actual chip or vendor name, for example Intel PRO/Wireless 4965 not just Integrated 802.11. The specs you gave are a bit light on those details. The best way to do this is run lspci on the box in the store as someone mentioned. Yes you will be able to install Linux on it for sure.

Hi, is there a way to get the num lock, caps lock and scroll lock state displayed in an OSD?

[gentoo-user] identical drives, different free space!
Hi, I have two 160Gb drives, one internal and one USB. I've partitioned them the same and created an identical filesystem on the USB drive for backing up my internal drive. I'm using the following rsync command to make the backup: sudo /usr/bin/ionice -c 3 /usr/bin/rsync -aAx --exclude suspend_file --delete --delete-excluded --partial --human-readable / /media/root-backup however, after running this command sporadically for a few days, the USB partition is now full, whereas my root partition isn't! sda is internal, and sdd is external. sda7 is the one I'm interested in: $ sudo fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0080 Device Boot Start End Blocks Id System /dev/sda1 1 11 883266 FAT16 /dev/sda2 * 12487539070080b W95 FAT32 /dev/sda348764888 104422+ 83 Linux /dev/sda44889 19457 117025492+ 5 Extended /dev/sda54889732119543041 83 Linux /dev/sda673227384 506016 83 Linux /dev/sda77385 1945796976341 83 Linux Disk /dev/sdd: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x5d5d0036 Device Boot Start End Blocks Id System /dev/sdd1 1 11 883266 FAT16 /dev/sdd2 12487539070080b W95 FAT32 /dev/sdd348764888 104422+ 83 Linux /dev/sdd44889 19457 117025492+ 5 Extended /dev/sdd54889732119543041 83 Linux /dev/sdd673227384 506016 83 Linux /dev/sdd77385 1945796976341 83 Linux I just deleted a bunch of /var/tmp and distfiles to free up some space, and ran the rsync again.

[gentoo-user] kernel notification of file system changes
Hi, I'm looking for some kernel-based notification of changes to my file system. I've been looking at inotify, but it's not exactly what I want. Basically I want to know if _any_ write occurs anywhere. I don't want to register a whole bunch of files to watch, I just want to watch an entire mount. When a file is changed (ie. a write operation occurs), I then want to add that file or fd to a list in RAM. That's all. I know this may be a lot of data, considering streams and devices, but I can filter out /dev, /proc, etc. and just focus on real files. Is there anything that can do this? thanks :) -- Iain Buchanan iaindb at netspace dot net dot au I hate it when my foot falls asleep during the day cause that means it's going to be up all night. -- Steven Wright

Sorry, I started ignoring that almost immediately it was posted. ooohh, ouch! :) He rejected too quickly too many workable solutions to basically functional backup. Perhaps Iain is a perfectionist, but I did not wish to follow the thread. Perhaps I am a bit of a perfectionist, but I think you misunderstood my aim. I rejected 3 options straight away (dd, gparted, and Ghost4Linux) because they're not designed for backing up a live filesystem in a change only fashion (intelligent is the word I used). Beyond that I didn't reject anything else that anyone mentioned. ... Inotify has two drawbacks which make it hard or even impossible to use for Iain's use case: a) It does not work recursively which means that you have to create a new handle for each subdirectory. Of course, this only means more work for the programmer but there is also the problem that Pardon me. I assumed that files inside the directory meant that foo would be be changed when foo/bar changed, thus monitoring grunt would reflect changes in grunt/foo/bar. I overlooked that a directory is not a file. isn't it? I thought a directory was just a file containing names (or inodes) of other files? Which would explain why monitoring grunt wouldn't show changes in grunt/foo/bar, since the directory/file called grunt remains the same (ie. contains the same list of inodes) even if grunt/foo/bar changes. Let me tell you what I actually want to do, which I may not have made clear originally: I want to backup root to an external drive (or that could be rephrased as I want to backup any mount to any other mount), such that: 1. My backup is an hour or so out of date (at most) 2. I don't need to copy the entire filesystem every time To do that, I could either: * Run rsync every hour over the entire filesystem (I'm doing this now with ionice, takes about 10 minutes when there are no changes) * Use some file notification monitor to tell me which file was just changed, and only rsync that file The problems with rsync is that during the rsync process, the filesystem is changing, so I will end up with a slightly inconsistent backup. If I use some notification method that tells me a file has changed, I can greatly reduce any inconsistency, and I reduce my hour down to seconds or minutes, depending on how much changes at any one time. I'm considering LVM for it's snapshot capability, but I'd still have to rsync root. I would prefer a file notification method as well, so I can just rsync the file that just changed. So far all the file monitoring tools are based on individual files (even the recursive ones), and you eventually reach a system limit.

[gentoo-user] recovering RAID from an old server
Hi all, I'm trying to recover some data from and old Snap Server 4200 (c2003) belonging to a local charity. It has 4 80Gb IDE drives, and runs some sort of Linux kernel with their (snap's) own applications on top. It won't boot to the Snap OS (Guardian OS 3.1.079 - quite an old one, major version 4 and 5 have succeeded it) but it does boot to a recovery console with a simple web page showing some details. From my google searches the OS resides on the disks (perhaps just the first one?) but I don't know where this recovery console is coming from. I've managed to put Gentoo 2008.0_beta2 minimal (because I happened to have the iso) on a USB key and made it bootable. It boots and fdisk -l shows me the four drives and some partitions. (Ubuntu wouldn't even boot ;) I don't have the original CD's with the OS recovery on it, nor can I download it (upgraded versions are $600+). I can't even find any *ahem* backup versions online in the usual channels. OK so the question: How can I recover the RAID data? It's RAID5 (probably) with 4 disks. Can I just run some up-to-date raid tools and mount the drives or do I have to get exactly the same kernal and setup? I don't have much experience with RAID. (It's software raid - no card just 2 IDE channels with master and slave). Once I've recovered the data I don't really care what goes on it - there are some great free NAS OS's, but it's mounting the RAID partition that I'm not sure about. Can I randomly mount partitions read-only or will this screw things up further? thanks for any suggestions, -- Iain Buchanan iaindb at netspace dot net dot au Don't fear the pen.

OK, I've randomly mounted partitions, and now I'm stuck because I don't
know what the original /etc/raidtab was. /proc/mdstat just says:
Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
unused devices: none
which looks like nothing is used in any RAID set. Autodetect seems not
to be working, perhaps because the ID wasn't set to 0xFD or 253. Each
drive has identical partitions:
Device Boot Start End Blocks Id System
/dev/hda1 * 1 2 16041+ 83 Linux
/dev/hda2 3 70 546210 83 Linux
/dev/hda3 71 138 5462105 Extended
/dev/hda4 139968276656636 83 Linux
/dev/hda5 71 104 273104+ 83 Linux
/dev/hda6 105 138 273104+ 83 Linux
and /dev/hd[aceg]1 is /boot on each one.
all the other /dev/hd[aceg][2-6] mount says:
mount: unknown filesystem type 'linux_raid_member
obviously this is the raid. But how do I get to it?
All /boots mount ok and are readable with some kernel files and stuff,
however /dev/hdc1 give some errors:
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x40 { UncorrectableError }, LBAsect=585, sector=575
hdc: possibly failed opcode: 0x25

And the deterioration in performance while each disk was removed in turn might take more time than its worth.

[gentoo-user] severe tearing and system lockup
Hi all, I've had this problem with various nvidia-drivers and never been able to track it down. AFAIR it only happens during certain (one?) xscreensaver hack. One of the 3d ones, but not necessarily one named GL* When the hack starts, I see multiple tears every 1-2cm (10-15 in all), each one offset to the right by the same amount. The colours look inverted, or neon. The screen is frozen. I can ssh in and initiate a shutdown, although it doesn't complete; or I can use the magic sysrq key. When the shutdown locks up, I can't use sysrq. Perhaps this is related, but when I run MoebiusGears with the settings maxed I can get performance like this: FPS: 220 Load: 100 Polys: 12000+ but sometimes on a different instance the FPS drops drastically to 90. Don't know why. I have: nVidia Quadro FX 1600M (laptop) 2.6.32-tuxonice-r1 x11-drivers/nvidia-drivers-190.53-r1 x11-wm/compiz-0.8.4 x11-base/xorg-server-1.7.4 any ideas? thanks, -- Iain Buchanan iaindb at netspace dot net dot au Harp not on that string. -- William Shakespeare, Henry VI
