Re: [arch-general] How big really is the MBR?

One of the NEW things im going to be trying is grub2. Now, the Grub2 wiki says to run dd if=/dev/zero of=/dev/sda bs=440 count=1 to wipe out grub-legacy from the MBR. And since the Arch-devs removed No Bootloader as an option in the AIF, you can't follow the during installation instructions for Grub2. Here's my problem, just by sheer luck was I roaming the web today, and noticed a few other threads (in various forums for various distros / blogs) and they all had a similar command to run if youre grub-legacy was screwed and you needed to write over it. The only issue, and the reason for this email? They had different commands. Not completly different, but different enough that raised an eyebrow. In dd if=/dev/zero of=/dev/sda bs=440 count=1 They had various numbers for bs=, some 440, some 446, some 506, and some 512. Normally I would've just shrugged and followed the wiki, but notice on one said that if you zero out too far, you wipe out hte partition table...which I wouldn't enjoy haha. So can anyone confirm that the command above, from the wiki, is correct? And that it IS 440, and not something different. I'd hate to pick the wrong one and zero out my partition table, or not completly zero out grub-legacy and run into a whole different set of problems. Thanks! grub gets installed in the first 440 (446) bytes, then some disk-specific data (optional), the rest takes up the partition table up to the 512th byte. look also at https://secure.wikimedia.org/wikipedia/en/wiki/Master_boot_record signature.asc Description: PGP signature

Re: [arch-general] Gnome 3, a bug?
This is such a basic issue that I refuse to believe I'm the first to bump into this behaviour. Hence I ask here first for some help. I recently upgraded to Gnome3 and switching between windows with alt+tab is rather broken for me. Here's why I say that: 1. I make sure I have two non-overlapping windows on the screen at the same time. 2. I position the mouse pointer in one of the window. 3. At this point I can't switch focus to the other window with alt+tab. Basically I have two options: 1. Move the mouse pointer so that it's not in any window, then I can use alt+tab. 2. Move the mouse to switch focus. Neither of these is very convenient. Does anyone recognise this? /M It's a design pattern of the GNOME Shell. Switching between windows work application based, not window based. Which means, if a Webbrowser is opened and two Shells, you won't switch between the shells but between Firefox and the last focused shell. You can get back the old behavior, though. Just install gnome-shell-extensions-git from AUR.
[arch-general] what about a gtk3-docs package?
Hi, I recently installed the dev tools for GNOME development and wondered why devhelp displayed no documentation for GTK3. Apparently there is no gtk3-docs package. Is it intented to not have that package (which makes no sense as there is the gtk2-docs package)? Now that GNOME 3 moved to [extra] it would be great to have the docs at hand. Thanks.

Re: [arch-general] Odd message on boot
It means, D-BUS (or any message bus) is missing a group specified in its configuration file. A solution might be to just create the group.
Re: [arch-general] [OT]Disk showing too many bad sectors - is it going to fail ?
The hard disk makes some funny noises (clicking, dangling, ...) and you wonder why some files are missing, though the disk is still useable. Linux should throw a bunch of errors at boot time, but Windows (98) continues with its work until something crashes. Partha Chowdhury schrieb am So 17.

I do not appear to have the tools installed on my Arch system that allow me to format as fat32 and can't find the command to format and set the label? Can this be done in one command step? You need to install the package dosfstools from [extra]. Then you can format your drive with mkfs.
