[arch-general] Random X server crashes
Hi, Occasionally (while using google chrome) my X server crashes completely and takes me back to the tty login. Examining the journal entries reveals the following highlighted in red: Sep 23 17:03:33 myarchbox kernel: [drm] nouveau :00:05.0: fail ttm_validate Sep 23 17:03:34 myarchbox kernel: [drm] nouveau :00:05.0: validate vram_list Sep 23 17:03:34 myarchbox kernel: [drm] nouveau :00:05.0: validate: -12 I am using the nouveau driver for my Nvidia graphics card. The problem is difficult to reproduce as it happens quite randomly - for instance I might be opening some particular website and it will crash. If I insist on opening the same website again it might crash a second time but it will work the third time or so. Is this a universal experience of using nouveau on Nvidia cards or is it something that is only afflicting my computer? Thanks. -- Aurko Roy GPG key: 0x20C5BC31 Fingerprint:76B4 9677 15BE 731D 1949 85BA 2A31 B442 20C5 BC31

[arch-general] Cannot see tty after starting X
Hi, I am unable to see the ttys immediately after starting X. Neither the original tty from which X was started nor the other unused ones seem to be visible. I have an Nvidia graphics card and I have tried using both the nouveau as well as the proprietary nvidia driver - but neither seem to work.

Previously, I had entered the following in my /etc/acpi/handler.sh to handle the acpi events generated when those keys were pressed: video/brightnessdown) echo $(($(cat /sys/class/backlight/acpi_video0/brightness) -1)) /sys/class/backlight/acpi_video0/brightness ;; video/brightnessup) echo $(($(cat /sys/class/backlight/acpi_video0/brightness) +1)) /sys/class/backlight/acpi_video0/brightness ;; However, as I am working on migrating to systemd, acpid no longer runs and hence does not handle these events. How can I write a similar handler into systemd? Thanks, Mike I used to reduce my brightness using a similar command in /etc/rc.local (/bin/echo -n 0 /sys/class/backlight/acpi_video0/brightness) but for the reasons that you mention this won't work anymore. I then switched to using X's brightness handler (xbacklight -set 0) which reduces display brightness as X starts. This is an easy solution but only works if you use X or if the delayed reduction in brightness is acceptable to you.

My apologies. I wasn't aware that the particular file you're trying to write to exists only if acpid is running. I personally went back to running acpid because systemd's handling of ACPI events is too rudimentary for my needs. As far as I understand from the manpage, you can only set under which conditions it should handle Lid/Sleep/Power button events. If these conditions are met, systemd handles these events the way systemd thinks they should be handled, and there seems to be no room to customize it. Since I never ever shut down my laptop except using halt or now systemctl poweroff, I found it convenient to set the action for power button events to be to put the machine to sleep, as this avoids the finger gymnastics required to activate the sleep button. This type of customization is possible using acpid but doesn't seem to be possible using systemd alone. Cheers, Norbert I see.

[arch-general] Systemd with encrypted Btrfs
Hello all, After all the intense discussions about systemd I decided to try it out and see for myself. I tried it out on my desktop and was quite impressed by it - it was much faster than the earlier initscript. Further when I would background a daemon (say the network daemon) in rc.conf, I would have to wait for a while even after I logged in for the network to start, whereas in systemd I find the necessary daemons have already started by the time I login. However I ran into a couple of problems running it on my laptop: 1. I have an encrypted swap that randomly generates a new passphrase everytime I reboot, but systemd asks me for a passphrase every time I boot. On pressing enter or entering any random characters it proceeds normally. This is more of an annoyance than a real problem. 2. I have an encrypted btrfs partition which it unlocks normally, but while trying to mount says: fsck: fsck.btrfs: not found fsck: Error 2 while executing fsck.btrfs for /dev/mapper/myvolume and this stops the whole boot process. I have to disable that partition on fstab to get systemd to boot properly. Once the boot process is complete, I can see that the decryption has proceeded normally (from systemctl -a) and can remount it normally in a manual fashion. I initially thought that creating fsck.btrfs as a symlink to btrfsck might do the job, but that doesn't work either. Does anybody have any experience successfully mounting (encrypted or not) btrfs partitions using systemd? Thanks, Aurko
Re: [arch-general] Systemd with encrypted Btrfs
Hi, Thanks for the quick reply. I wasn't aware of the changes in crypttab syntax with systemd; but changing it the way you described it did the trick for swap. You're right, on digging deeper (logs) I found that the fsck had failed earlier as well but I never noticed it as the boot process wasn't interrupted. I didn't face it again after setting passno. to 0. I had heard about btrfs being released without a proper fsck in place but I thought that was long ago and that btrfsck was ready for general use. Rodrigo: I already solved it, but thanks for your reply anyway. -aurko On Tue, Jul 24, 2012 at 3:09 PM, Tom Gundersen t...@jklm.no wrote: On Tue, Jul 24, 2012 at 10:58 AM, Aurko Roy roy.au...@gmail.com wrote: 1.

On pressing enter or entering any random characters it proceeds normally. This is more of an annoyance than a real problem. Note that systemd does not support Arch's traditional crypttab syntax, so you might need to adjust your crypttab file. The format is described in man crypttab. I have a similar setup to what you describe and my crypttab line is: # cat /etc/crypttab swap/dev/sda2 /dev/urandomswap 2.

I initially thought that creating fsck.btrfs as a symlink to btrfsck might do the job, but that doesn't work either. There is no fsck.btrfs binary yet, and btrfsck does not support the expected interface. Until a proper fsck.btrfs exists you should mark your partition as not wanting to be fsck'ed in fstab (i.e. set passno, the last argument, to 0). Does anybody have any experience successfully mounting (encrypted or not) btrfs partitions using systemd? I would have thought you'd get a similar failure also with initscripts? Though in that case boot would not pause. -t
Re: [arch-general] Systemd with encrypted Btrfs
Hi, Thanks for the clarification. Also I was wondering if there was any reason why Arch doesn't have the rc-local.service in systemd by default. There was some stuff I ran in rc.local (reducing brightness, proxy authentication) but it seems there is no rc-local service in systemd. I am working on copying content from fedoras rc-local.service and trying to get it to work on my laptop. -aurko On Tue, Jul 24, 2012 at 3:46 PM, Tom Gundersen t...@jklm.no wrote: On Tue, Jul 24, 2012 at 12:10 PM, Aurko Roy roy.au...@gmail.com wrote: You're right, on digging deeper (logs) I found that the fsck had failed earlier as well but I never noticed it as the boot process wasn't interrupted.

I have been using btrfs as my rootfs on all my machines for a couple of years and never seen a corruption that required fsck, so I don't know how well (or not) btrfsck actually works. I would assume it would not be too bad, as it is shipped by at least Oracle. The problem though is that it does not implement the correct API for integration with regular fsck, so it can only be called manually and not automatically on boot. -t
Re: [arch-general] Systemd with encrypted Btrfs
Hi, Yeah it works fine with the initscripts-systemd package but I had replaced that with the systemd-sysvcompat package for a pure systemd setupd. I was wondering if there is a reason why they've discontinued support for rc.local in that. AFAIK Fedora has a pure systemd setup (I may be wrong there) but still support rc.local. Perhaps I'm missing/misunderstanding something.

Have a look at the initscripts-systemd package, it contains rc-local and rc-local-shutdown service files.
Re: [arch-general] Systemd with encrypted Btrfs
Hi,
Thanks for your answer. In the end I decided to stick with
systemd-sysvcompat with my own rc-local.service (since I didn't need
the other stuff in the initscripts-systemd package). I must say I'm
starting to like systemd despite the minor hiccups due to changes in
conventions.

Fedora still have quite a bit of legacy stuff (probably even more than
what we do). I'd argue that rc.local{,.shutdown} is legacy, and that
people would be better off by either writing .service files, or fixing
whatever bugs are being worked around (which is mostly the use-case)
properly.
Even if you use systemd-sysvcompat support, you are of course free to
copy the rc-local serivce files from the initscripts-systemd pacakge
and put them in /etc/systemd/system/
