Re: [gentoo-user] USB Flash Drives automatic mounting breakage (Gnome)
2010/1/5 Alan E. Davis lngn...@gmail.com: It seems to me that it is possible to unmount the drives manually, many times, if not always, if it is impossible to unmount them via nautilus. Other File Managers work differently, I think Thunar may be more straightforward, not sure, though. Maybe this will all pass soon enough, but for now, on one of my machines, especially, I have to reboot frequently. If it's hal that is at work, then perhaps I can restart that? But when I did something similar, the window manager, at least, restarted. I'm at my machine now and can report as follows: Mounting a USB stick manually by running: $ pmount /dev/sda1 gives me this mounted device: /dev/sda1 on /media/sda1 type vfat (rw,noexec,nosuid,nodev,quiet,shortname=mixed,uid=1000,gid=441,umask=077,fmask=0177,dmask=0077,iocharset=iso8859-1) which I *cannot* unmount using Konqueror. Selecting 'safely remove' does not do anything (and I can't see any messages in the logs on this version of Konqueror). Mounting the device using Konqueror allows me to unmount it both using the Konqueror GUI and manually by issuing pumount /dev/sda1. PS. I have not set up any fancy USB rules for this drive. -- Regards, Mick

[gentoo-user] {OT} Laptop wifi find more than external antenna
I travel with a USB wifi dongle and one of these directional antennas: http://www.newegg.com/Product/Product.aspx?Item=N82E16833164110 Lately I've noticed there are some APs that my laptop's internal wifi connects to perfectly, but the external antenna can't find whatsoever, even after a lot of directional experimentation. I've tried 2 different USB dongles with the same result. Has anyone had a similar experience? I'm baffled because the external antenna is able to make strong connections to some APs, but it can't even find others that the laptop's internal card finds and connects to no problem. - Grant
