I read: https://wiki.archlinux.org/index.php/Display_Power_Management_Signaling#DPMS_interaction_in_a_Linux_console_with_setterm http://webpages.charter.net/dperr/dpms.htm and so far I have not found a way to repeat the poweroff that worked on first boot. I did install the nvidia package for future use, which pulled in xorg-server as a dependency, but X is not started. I don't see why that would influence console behavior. Well, that certainly is a difference. The nvidia package includes the file `/usr/lib/modprobe.d/nvidia.conf` that contains the line `blacklist nouveau`. That's necessary because if the nouveau driver is loaded first, then the nvidia one cannot work properly. But you are not loading X, so I'm guessing that your nvidia driver is not being loaded either (the kernel driver is probed by the X driver IIRC), so you are running with the default vesa console. You can try running `modprobe nvidia` and see if it makes a difference. If that's not the case, reboot and run `modprobe nouveau`. Or maybe I'm wrong and the nvidia driver is being loaded automatically. If that's true, you can try blacklisting it and modprobing nouveau. Best regards -- Rodrigo.

[arch-general] New users not automatically added to 'users' group if -g default group specified?
All, In the past with arch installs, new users have always been added to the 'users' group. Now that is not being done. If I recall correctly, I have always specified that users are members of a group with the same name as the user by manually creating the group and using the useradd -g group option. This was done to keep UID and GID numbers the same across multiple boxes. On older installs all users were made part of the users group: (July 2011 install) [08:31 nirvana:/etc/httpd/conf] # grep users /etc/group users:x:100:david,anna,blah,blah,blah (New install) [08:45 phoinix:/etc] # grep users /etc/group users:x:100: Is this expected behavior, or has something gone wrong with the install? I ask because https://wiki.archlinux.org/index.php/Cron#Users_and_autostart suggest that all users should already be members of the 'users' group. I don't mind manually adding the users, but if this is a bug, I'll report it. -- David C. Rankin, J.D.,P.E.

[arch-general] Fwd: Problem with kvm + virt-manager
Hi, I'm spanish. I love archlinux. I used debian, opensuse, ubuntu,
fedora, linux mint, fuduntu, gentoo and I like arch above all. I will
install kvm in arch. I follow this guide:

I have installed vmware workstation and virtualbox and works very well.
But in kvm, when I create de VM I receveid this error:

Can I help me please?? Is a bug of the virt-manager??

This is done to save space in /etc/group on systems with large number of users. My speculation would be that in 2011, you ran useradd -m -g users -G users,audio,... david.

Well, the proprietary nvidia is known for focusing on X, the console has been neglected, no KMS, basic DPMS, it seems... The OS nouveau driver, however is doing things properly, if you have the luck that your hw is supported. Nouveau - more features, less performance. Nvidia - less features, more performance. Pick one. Now, if you want to switch between them without rebooting, you can try to remove one driver and modprobe the other. I wouldn't bet on the stability of your kernel, though. A safer solution would be to create two entries in the boot menu (grub or whatever): one will blacklist nouveau, the other will blacklist nvidia. With a bit of work you can even switch the mesa/libgl links to point to the proper versions! Best regards. -- Rodrigo

[arch-general] Patch for update-mime-info slowness
I am kind of annoyed by the time it takes to update the MIME database (something like two minutes on a recent i7 quad-core laptop). Until pacman has hooks/triggers, I have removed the calls to fdatasync (which are supposed to ensure that the files are truly written to disk). I prefer letting the system take care of it anyway, and I don't care much for consistency in desktop links and file associations. Y'know, it might bear the name database, but it's not a database in the sense of a +1M row postgresql database). Anyone have an opinion on this? Am I a complete idiot in removing these calls to fdatasync? With this patch, updating takes around 5 seconds, haven't run it with a stopwatch yet. -- Sébastien Leblanc
