Re: [gentoo-user] Blue Fn Key Combinations not Sending Scancodes
Randy Westlund rwest...@gmail.com wrote: Hey guys, I'm trying to make my blue Fn key combinations control by MPD server on the Raspberry Pi sitting on my speakers. This should be really easy with xbindkeys. I'm following this document: http://www.gentoo-wiki.info/HOWTO_Use_Multimedia_Keys The problem I have is that the Fn key combinations on my laptop aren't all sending scancodes. I understand that the Fn key itself doesn't send a scancode. I'm using Fn + Down Arrow (a blue play/pause symbol), but xev doesn't register it. Even when running showkey -s, I can't get a scancode. When I do Fn + F8 (a blue monitor symbol) I get the scancode 0xe0 0x56 0xe0 0xd6 so the key itself is working. And I can use Fn + F1 (Zz) to hibernate. So I'm thinking the kernel isn't recognizing the scancode that the keyboard is sending? Does that sound right? Is there something in the kernel that I should change? I didn't see anything that looked relevant under keyboard drivers. Randy On an old laptop of mine I had to use ACPI to get the events from some of those.

Usually I don't start xfce at all, but for the times when I do, I'd be nice to do this without editing a file. Can I simplify this process? Is there anyone else who uses multiple WMs? How do you manage them? If you use xinit instead of startx, you can use the environmental variable ~ $ XINITRC=.xinitrc-xmonad xinit -- :1 should do what you want.

The problem is caused by stacking tcp packets (tcp within tcp) each of which is using its own timeout for failed fragments. The problem is explained here (tcp meltdown): http://sites.inka.de/~W1011/devel/tcp-tcp.html and here (useful relevant references to other works are also made): http://publications.lib.chalmers.se/records/fulltext/123799.pdf There are some suggested solutions like increasing buffer size, but I don't know this might work in a real world use case. You can experiment with different buffer sizes as suggested here and see if it makes a difference: http://www.cyberciti.biz/faq/linux-tcp-tuning/ If the interruptions are not acceptable to you, you could consider using a different tunnel method. A network layer VPN, like IPSec (you can use StrongSwan which also offers IKEv2 and MOBIKE for your laptop, or ipsec-tools with racoon for IKEv1 only) should work without such problems. You will be tunnelling tcp in udp packets. If you tunnel to your home router you will need to configure an IPSec tunnel mode connection, otherwise you would use an IPSec transport mode connection directly to your server after you allow IP protocol 50 packets through your router.

[gentoo-user] Makeing /dev/rtc1 accessible as soon as possible - how?
Hi, There are two RTCs in my system: /dev/rtc0 and /dev/rtc1 rtc0 is not powered by a battery and forgets time/date with system shutdown and rtc1 is a I2C-rtc (DS3231) which is powered by a battery. It is extremly accurate in comparison with rtc0. rtc0 is accessible with system boot - rtc1 is not (current state). To make rtc1 completly know to the system, I have to do a echo ds3231 0x68 ! /sys/bus/i2c/devices/i2c-1/new_device hwclock -f /dev/rtc1 -s in beforehand. I wrote a script for /etc/init.d, which does exactly this, and the system login screen shows the correct tome/date information even without ntp-client (the system should become independantly from lan/internet). The script was added to the boot service and executed after dev and modules. The kernel is configured to use /dev/rtc1 and the driver for the ds1307, which also handles the ds3231, is included into the kernel (no module). But it seems, that setting the system time this way is too late, since there are still (for example) log files under /var/log with a timestamp of the 1.1.1970. Are there any other way to make rtc1 known and accessible earlier to the system as the hack via a script in /etc/init.d ? Thank you very much in advance for any help! Best regards, mcc
